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.
SUMMARY OF THE INVENTIONAccordingly, 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.
