Abstract
Abstract of the Disclosure An electrical connector terminal for a flexible printed circuit board which has an elongated plate-like bottom section, a plurality of projections rising from both edges of the bottom section and a contact piece coupled at one end thereof to the bottom section so as to extend over the bottom section with the printed cir-cuit board therebetween, the contact piece being fixed to the printed circuit board in a manner such that the projections are bent to press and hold the contact piece against the surface of the circuit board.
Description
~ ~ ~ 6 ~ ~
The present invention relates to an electrical con-nector terminal for a flexible printed circuit board and more particularly to a terminal which provides more reliable mechanical and electrical connection to the circuit board.
Several types of electrical connector terminals have been used for flexible printed circuit boards. Figs. 4a and ~c illustrate one type wherein the terminal has an elongated plate-like strip 41 with integrally formed pro;ections 42 extending upward at the sides. The strip portion of the terminal is located under a conductor 5a of a flexible printed circuit board 5 so that the pro-~ections 42 penetrate the circuit board at both sides of the conductor 5a. The ends of projections 42, which are sticking out of the top surface of the board, are then bent onto the conductor 5a of the flexlble circuit board and fixed directly to the conductor by crimping for electrical connection, as shown in Fig. 4c. Another variation of this type of terminal for a flexible cir-~0 cuit board is shown in Figs. 4b and 4d. In thisvariation, the terminal has a group of projections 42 extending from the flat upper surface of its plate-like strip 41. Thus, when located beneath a conductor 5a of the flexible circuit board, the projections 42 will penetrate the board and conductor sa directly from below. The pro;ections 42 are then bent and crimped directly to the conductor 5a by crimping as shown in - , ' ' ~- .
Fig. 4d. In both the foregoing examples, the clamping force exerted by the ends of the pro]'ections 41 is small since the circuit board onto which the ends are directly fixed by crimping is flexible. The junction between the flexible circuit board and the projections are therefor more likely to be loosened by external factors such as heat, vibration, the bending of the circuit board and the like, thereby making the electrical connection unstable.
Fig. 5 shows another prior art terminal which is somewhat similar to the terminal disclosed in U.S.
Patent No. 3,997,233 issued December 1~, 1976 to Robert F. Evans and assigned to same assignee as the present application. The terminal in Fig. 5 comprises two 1~ contact pieces 51 and 52 which are adapted to hold a flexible printed circuit board between them. Piece 51 has opening 53, while piece 51 is formed with projection 54 ~hich can be fitted into opening 53. The flexible printed circult board is clamped between contact pieces ~0 51 and 52 of the terminal so that projection 54 of piece 52 penetrates the conductor portion of the flexible circuit board and sticks out behind piece 51 through opening 53. The projecting end of projection 5~ is bent and fastened to the reverse side of contact piece 51 by crimping. In this arrangement, contact piece Sl, on which projection 54 is directly fitted by crimping, is a strong metal piece, so that the terminal can~clamp the .
'' , flexible printed circuit board firmly. However, since the flexible circuit board is formed with a cut across its conductor which is adapted to be penetrated-by pro-]'ection 5~, the conductor is fragile and may possibly be broken, depending on its pitch of arrangement.
The ob;ect of the present inv~ntion is to provide an electrical connector terminal for a flexible printed circuit board which can be fastened securely to a metal piece by crimping without piercing or breaklng the con-ductor of the circuit board instead of being crimpeddirectl~ to the flexible circuit board itself.
According to the present invention, there is pro-vided an electrical connector terminal for a flexible printed circuit board which comprises an elongated lS plate-like bottom section or base, a plurality of pro-~ections or tabs rising from both edges of the bottom sectlon and a contact piecè coupled at one end thereof to the bottom sectlon so as to extend over the bottom section with the printed circuit board therebetween, the ~0 contact piece being to be fixed to the printed circuit board in a manner such that the projections are bent to press and hold the contact piece against the conductor on the surface of the circuit board.
In the electrical connector terminal for a printed circuit board constructed in this manner, the pro~ec-tions are crimped to the contact piece which overlies the conductor of the flexible circuit board instead of .
being crimped directly to the flexible printed circuit board. Thus the terminal can clamp the flexible circuit board securely. Arranged along both side edges of the bottom section, moreover, the projections do not penetrate the conductor of the circuit board and therefore cannot break the conductor. Situated in th.is manner, furthermore, the projections cannot be dislocated by the crimping work and can be fixed securely to accurate positions.
This invention can be more fully understood from the following detailed description when taken in con-~unction with the accompanying drawings, in which:
Fig. 1 is a perspective view of a connector ter-minal according to an embodiment of the present inven-tion;
Fig. 2 is a side view of the connector terminalshown ln Fig. l;
Fig. 3 is a perspective view showing several of the connector terminals of Fig. 1 mounted on a flexible ~0 printed circuit board; and Figs. 4a-4d and 5 are perspective views showing different types of prior art connector terminals.
A preferred embodiment of the present invention is shown in Figs. 1 to 3. The electrical connector ~5 terminal includes an elongated plate-like bottom section or base 1 and an elvngated top section or contact piece 2. The base and contact piece are formed integrally so that the contact piece 2 extends from one end of the base 1 through a reverse angle bend and back over and above the top surface of the base 1. The contact piece 2 can easily be pressed downward toward the base. The terminal shown has another extension from the base for mating the terminal with, for example, another connec-tor.
~ ro;ections or crimp tabs 3a and 3b are formed lntegrally at the two opposite side edges of the base 1 and extend upward toward the contact piece 2. In this embodiment of Figs. 1-3, three crimp tabs are shown. A
relatively wide crimp tab 3a is formed along one side edge of the base 1 while two somewhat narrower crimp tabs 3b are ~ormed along the other side edge. The tabs are arranged so that crimp tab 3a on the one side edge of base 1 is opposite the gap or space between the two crimp tabs 3b on the other side edge of base 1. In order to prevent dislocation of the contact piece 2 during crimping, in particular, it is preferable to ~0 provide at least three crimp tabs.
Fig. 3 shows several of the above-described termi-nals mounted on an flexible circuit board 5. The circuit board has a number of conductors 5a and each terminal is mounted so that its contact piece 2 is in electrical contact with one of the conductors 5a. This is accom-plished by inserting the flexible circuit board 5 between the base 1 and contact piece 2 of the terminal and aligning the conductor 5a so that it extends lengthwise between the base 1 and contact piece 2 and faces the latter. The crimp tabs 3a and 3b penetrate the flexible circuit board from the bottom through the top surface on opposite sides of the conductor Sa but do not piece the conductor~ The contact piece 2 is then pressed against the conductor 5a on the upper surface of the flexible printed circuit board 5 so that good electrical contact is achieved between the two. Thereafter, crimp tabs 3a and 3b are bent down over the top of the contact piece 2 and then fastened thereto by crimping. Each comlector termlnal can thereby be fixed to this flexible printed circuit board so that its contact piece 2 is in electri-cal contact with a conductor 5a of the flexible printed lS circuit board. Since crimp tabs 3a and 3b are secured to the metallic contact piece by crimping, the terminal and ~lexible printed circuit board are reliably interconnect-ed both mechanically and electrically without penetration or tearin~ of the fragile conductors on the circuit ~0 board.
For an even more reliable connection, the lower surface of contact piece 2 can be provided with a protrusion 4. Likewise, the upper surface of the base 1 may be provided with a protrusion 4' aligned with the protrusion 4 in the contact piece 2. When the contact piece 2 is crimped to the conductor 5a on the flexible circuit board, the protrusions ensure good electrical ~: ' ' , ' . `
