Description

Technical Field

[0001] The present application relates to an optical communication connector. Background Art

[0002] With the development of electrical connectors, especially high-speed connectors, stacked electrical connectors are becoming more and more common. Such electrical connectors usually include an upper socket and a lower socket. From a structural point of view, the stacked electrical connector generally includes an insulating body, a plurality of conductive terminals, and a metal shell surrounding the insulating body.

[0003] In some installation methods, after the insulating body and the conductive terminals are assembled, they are first installed on a circuit board, and then the metal shell is installed from top to bottom on the outside of the insulating body and fixed to the circuit board. For details, please refer to Chinese invention patent CN113422243B. In the stacked electrical connector of this installation method, the upper socket can be formed by a stopper 61 formed by bending the top plate of the metal shell 3 to limit the insertion depth of the docking plug and prevent the docking plug from being inserted excessively. However, in order to avoid mutual interference between the metal shell and the insulating body during installation, a stopper for the lower socket cannot be formed on the metal shell.

[0004] Therefore, in the patent CN113422243B, an independent stopper 51 is implanted in the lower socket. However, in this method, since the stopper 51 is made of plastic and is implanted in the lower socket by assembly, it is easy to be misaligned or deformed when colliding with the docking plug, and there is even a risk of falling off. If the material of the stopper 51 is changed to metal, there is a risk of miscontact (electrical contact) or even short circuit. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] Please refer to Figures 1 to 9 As shown, the optical communication connector 100 shown in the present application includes a terminal module 10, a metal housing 3 used in conjunction with the terminal module 10, and a stop member 4 assembled and fixed on the terminal module 10. The optical communication connector 100 can be assembled to a docking circuit board 200, and the docking circuit board 200 can be a substrate member in an electronic device / communication facility.

[0029] The terminal module 10 includes an insulating body 1 and a plurality of conductive terminals 2 fixed in the insulating body 1. The front end of the insulating body 1 is recessed backward to form a first slot 110 and a second slot 120, and the first slot 110 and the second slot 120 are independently arranged at intervals along the thickness direction of the docking circuit board 200. Each of the conductive terminals 2 is made of metal material, including a fixed section (not numbered) fixed in the insulating body 1, a contact section 21 extending from the fixed section into the first slot 110 or the second slot 120, and a docking section 22 extending from the fixed section out of the insulating body 1. The contact section 21 corresponds to electrical contact with the docking connector, and the docking section 22 corresponds to electrical contact with the docking circuit board 200. In the embodiment of the present application, specifically: the docking section 22 extends downward from the lower surface of the insulating body 1 out of the insulating body 1. The plurality of contact sections 21 are arranged in two rows along the width direction and correspond to the upper and lower inner wall surfaces of the first slot 110 respectively. The plurality of contact sections 21 are arranged in two rows along the width direction and correspond to the upper and lower inner wall surfaces of the second slot 120 respectively.

[0030] Please refer to Figures 1 to 4 As shown, the metal shell 3 includes a top wall 31, a bottom wall 32, two side walls 33 connecting the top wall 31 and the bottom wall 32, a rear wall 34 connecting the top wall 31 and one end of the two side walls 33, and a partition side wall 36 arranged between the two side walls 33 along the width direction. The top wall 31, the bottom wall 32, the two side walls 33 and the rear wall 34 are jointly arranged to form a receiving cavity 301. The partition side wall 36 divides the receiving cavity 301 into a left receiving cavity (unnumbered) and a right receiving cavity (numbered). Further, in the illustrated embodiment of the present application, the metal shell 3 also includes a partition 35, which is arranged between the top wall 31 and the bottom wall 32 to divide the receiving cavity 301 into an upper insertion cavity 3011 and a lower insertion cavity 3012. Specifically, the left receiving cavity is divided into a left upper insertion cavity 3011 and a left lower insertion cavity 3012 arranged in the up-down direction; the right receiving cavity is divided into a right upper insertion cavity 3011 and a right lower insertion cavity 3012 arranged in the up-down direction.

[0031] The metal shell 3 is also formed with a terminal module implantation port 30, which is formed between the front edge of the bottom wall 32 and the partition 35 along the insertion direction of the docking connector and the rear wall 34, and connects the front end portion of the receiving cavity 301 along the insertion direction of the docking connector downward to the outside world. Specifically, the terminal module implantation port 30 is divided into two arranged left and right by the partition side wall 36, one of which connects the left upper insertion cavity 3011 and the left lower insertion cavity 3012 downward to the outside world; and the other connects the right upper insertion cavity 3011 and the right lower insertion cavity 3012 downward to the outside world.

[0032] In the illustrated embodiment of the present application, the terminal modules 10 are provided with two, respectively corresponding to the two terminal module implantation ports 30. Of course, in other embodiments, the terminal module 10 may be provided with only one, and correspondingly, the metal shell 3 is also synchronously matched to provide only one left receiving cavity or one right receiving cavity, in which case the partition side wall 36 is also the side wall 33.

[0033] Taking a terminal module 10 as an example, along the plugging and unplugging direction of the docking connector, the upper insertion cavity 3011 of the metal shell 3 is connected to the first slot 110, and the lower insertion cavity 3012 is connected to the second slot 120. The stop member 4 is an independent metal member and is fixed to the insulating body 1 by a detachable assembly. Figures 2 to 9 As shown, the stop member 4 is arranged on a side surface (lower surface) of the insulating body 1 facing the docking circuit board 200 and near the front end (i.e., the insertion end of the docking connector). The stop member 4 is formed with a stop end 401, and the stop end 401 is exposed forward into the receiving cavity 301 and is configured to abut against the docking connector inserted into the receiving cavity 301 to prevent the docking connector from being over-inserted. Specifically, the stop member 4 includes a main body plate 41 and buckle pieces 42 formed by extending upward from both side edges of the main body plate 41. The buckle pieces 42 are fixed to the outer surface positions on both sides of the insulating body 1, and the stop end 401 is formed at the front end of the main body plate 41 along the direction of pulling out the docking connector.

[0034] In a preferred embodiment, the outer surfaces of both sides of the insulating body 1 are recessed to form an embedding groove 102. The buckle piece 42 includes an arm piece 421 and an embedding piece 422 formed by extending from the free end of the arm piece 421. At least a portion of the arm piece 421 corresponds to the outer surface of the insulating body 1 (in the illustrated embodiment, it is shown as: the upper end portion of the arm piece 421 corresponds to the outer surface of the insulating body 1), and the embedding piece 422 corresponds to the embedding groove 102. In a preferred embodiment, the embedding groove 102 extends along the plugging and unplugging direction of the docking connector, and the front end of the embedding groove 102 along the unplugging direction of the docking connector is open forward and forms an embedding opening 1021. The embedding piece 422 of the stop member 4 slides and embeds into the embedding groove 102 through the embedding opening 1021 of the embedding groove 102 along the insertion direction of the docking connector.

[0035] Please refer to Figures 3 to 9 As shown, the outer surface (the two end surfaces in the width direction) of the insulating body 1 is protruded with a protruding portion 5. Along the thickness direction of the docking circuit board, the protruding portion 5 is located between the embedding groove 102 and the docking circuit board 200. A snap-fitting hole 423 is formed through the arm piece 421. When the embedding piece 422 of the stop member 4 slides and embeds to a certain depth of the embedding groove 102 through the embedding opening 1021 of the embedding groove 102 along the insertion direction of the docking connector, the snap-fitting hole 423 is snap-fitted with the protruding portion 5.

[0036] In a preferred embodiment, the insulating body 1 is recessed at the front end position (near the insertion port) of the side surface facing the docking circuit board 200 to form a clearance opening 101, and the clearance opening 101 is open to the receiving cavity 301 along the removal direction of the docking connector, and the two ends of the clearance opening 101 along the width direction are open (that is, the two side positions of the insulating body 1), and the stop member 4 is assembled and fixed to the position of the clearance opening 101. In the up-down direction, the main body plate 41 is arranged opposite to the inner wall surface of the clearance opening 101 at intervals. The front end edge position of the main body plate 41 along the removal direction of the docking connector is protruded along the up-down direction toward the side away from the docking circuit board 200 to form a stop portion 40, and the stop end 401 is defined by the front end edge of the stop portion 40 along the removal direction of the docking connector.

[0037] Furthermore, the insulating body 1 is formed with a stop groove 103 at a position adjacent to the clearance opening 101 on the side facing the docking circuit board 200, and the stop groove 103 is open along the removal direction of the docking connector. The front end edge of the main plate 41 along the insertion direction of the docking connector is correspondingly inserted into the stop groove 103. In one embodiment, the stop groove 103 is open toward the docking circuit board 200, and the lower surface of the main plate 41 is flush with the lower surface of the insulating body 1. In another embodiment, the stop groove 103 is open only toward the removal direction of the docking connector, and the front end edge of the main plate 41 in the insertion direction of the docking connector is inserted into the stop groove 103 along the insertion direction of the docking connector. The stop groove 103 is used to prevent the stop member 4 from being excessively inserted along the insertion direction of the docking connector when it is assembled to the insulating body 1.

[0038] In one embodiment of the optical communication connector of the present application, the terminal module 10 assembled with the stop member 4 is assembled and fixed to the docking circuit board 200 from top to bottom, and then the metal shell 3 is assembled from top to bottom to the periphery of the terminal module 10 and fixed to the docking circuit board 200. The terminal module 10 assembled with the stop member 4 is an independent component, and the metal shell 3 is an independent component, and the two are only used in conjunction with each other. Another embodiment can be: the terminal module 10 assembled with the stop member 4 is inserted from bottom to top through the installation opening (30) and assembled and fixed into the metal shell (3) to form an integral component, and when used, it is installed on the docking circuit board 200 as a whole at one time.

[0039] In the present application, the front edge of the stop member 4 is located behind the front edge of the insulating body 1. By designing the stop member 4 and the metal shell 3 as two independent pieces and fixing the stop member 4 to the insulating body 1 separately, when assembling the metal shell 3, there will be no problem of interference between the metal shell 3 and the insulating body. In addition, the second slot 120 located below the optical communication connector of the present application can also achieve the insertion stop function for the docking connector.

[0040] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
