1. Field of the Invention
The present invention relates to an LC-type optical connector assembly, and particularly to a low profile LC-type optical connector assembly.
2. Description of Related Art
Optical fiber connectors are widely used in optical communication systems to join optical fibers together to form a longer length fiber run, or to connect an optical fiber to a device. An SFF (Small Form Factor) and an SFP (Small Form-factor Pluggable) standard were introduced into the industry to meet a demand for high-density communication ports. An LC-type optical connector is a kind of SFF standard optical connector which can be used to connect with an SFF or an SFP transceiver.

However, the latching arm 12 extends slantways from the connector body 11 at a relatively high angle, which results in a large height of the connector assembly 1. Furthermore, the free end of the trigger arm 132 overlies the distal end 122 of the latching arm 12, which further increases the height of the connector assembly 1. This kind of high profile connector assembly is not suitable to connect with a transceiver in a device having high-density communication ports.
Therefore, an improved optical connector assembly is required to overcome the disadvantage described above.
Accordingly, an object of the present invention is to provide a low profile optical connector assembly.
In order to achieve the object set forth, an optical connector assembly comprises two optical connectors and a combiner. Each optical connector comprises a connector body and an angled latching arm formed on the connector body. The latching arm further comprises a fixed end on the connector body and a free distal end, and a groove is defined on the distal end. The combiner comprises a combiner body holding the optical connectors and a cantilevered trigger arm. The trigger arm comprises a fixed end on the combiner body and a free distal end. A rod is formed on the distal end of the trigger arm, and is received in the grooves of the latching arms.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
The connector body 30 comprises an angled latching arm 4 extending slantways upwardly at a shallow angle from the connector body 30 and adjacent the front end 31. The latching arm 4 comprises a fixed end 41 formed on an upper surface 311 of the connector body 30 and a free distal end (not labeled). The latching arm 4 further comprises a first portion 42 extending slantways at an angle from the fixed end 41 and second portion 43 substantially parallel to the connector body 30. Two tabs 421 extend laterally from two sides of a rear end (not labeled) of the first portion 42, where the first and second portions 42, 43 are joined at an obtuse angle. The tabs 421 are adapted to engage with one of two receptacles (not shown) of a transceiver (not shown) to latch the optical connector 3 therein, and can be detached therefrom by manipulating the combiner 5, which will be described in detail hereinafter. A groove 430 is laterally defined on the distal end of the latching arm 4. The groove 430 further comprises an entrance aperture 431 and a receiving slot 432 in communication with the entrance aperture 431. A protrusion 321 extends from a side surface (not labeled) of the connector body 30 for positioning the combiner 5.

The trigger arm 7 is T-shaped, and comprises a fixed end (not labeled) formed on the combiner body 6 and a free distal end (not labeled) extending slantways at an angle from the fixed end. The trigger arm 7 has a generally same height as the latching arm 4. A cylindrical rod 72 extends laterally on either side of the distal end of the trigger arm 7. The trigger arm 7 further comprises a serrated outer surface 71 to aid manual operation.
As described above, the angled latching arm 4 extends slantways at a shallow angle from the connector body 30, and the trigger arm 7 has a generally same height (or the uppermost surfaces 43A, 7A of each of latching arms 4 and trigger arm 7 extend an equal distance “D” in
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
