[0002] The present invention relates to a connector and a connector assembly including the connector.

Background Art

[0003] In the prior art, a Type - C connector typically includes a connector connected to a cable and a mating connector connected to a circuit board. The connector mates with the mating connector to achieve a rapid electrical connection between the cable and the circuit board. In the prior art, the connector typically includes a housing and an electrical connection module inserted into the housing. The electrical connection module includes a mating end for mating with the mating connector, and the mating end extends from the front end of the housing and is inserted into the mating housing of the mating connector. The electrical connection module of the connector usually includes an insulator located at the mating end of the electrical connection module, an upper row of terminals and a lower row of terminals arranged on the insulator, and a shield shell attached to the insulator. In the prior art, since the mating end of the electrical connection module of the connector extends from the housing, the mating end of the electrical connection module is likely to collide during packing or transportation, which may lead to damage and failure of the mating end of the electrical connection module. Also, since the mating end of the electrical connection module of the connector extends from the housing, the anti - vibration performance of the connector may be insufficient, and the electrical contact is likely to become unstable in a vibration environment.

[0033] As shown in Figures 1 to 8, an exemplary embodiment of the present invention discloses a connector 1. The connector 1 includes a housing 18 and an electrical connection module 10. The housing 18 has a front port 181 and a rear port on both sides in the longitudinal direction Y of the housing 18. The electrical connection module 10 is inserted into the housing 18 from the rear port of the housing 18. The electrical connection module 10 has a mating end 10a located in the front port 181 of the housing 18, and the mating end 10a is used to mate with a mating plug 21 of a mating connector 2 inserted into the front port 181 of the housing 18.

[0034] As shown in Figures 1 to 8, in the illustrated embodiment, the front end of the housing 18 extends beyond the mating end 10a of the electrical connection module 10, thereby completely concealing the mating end 10a of the electrical connection module 10 within the front port 181 of the housing 18.

In the illustrated embodiment, the rear shield shell 16 comprises an upper shield shell half and a lower shield shell half assembled together.

[0045] As shown in Figures 1 to 8, in the illustrated embodiment, the rear shield shell 16 has a crimping portion 161 located at the rear end of the rear shield shell 16, and the crimping portion 161 of the rear shield shell 16 is crimped to the shield layer 141 of the flat cable 14.

[0046] As shown in Figures 1 to 8, in the illustrated embodiment, a first recess 16a is formed in the upper wall of the rear shield shell 16 and is welded to the shield layer 141 of the flat cable 14. The rear end of the circuit board 13 is located outside the injection molded body 17, and a second recess 16b is formed in the bottom wall of the rear shield shell 16 and is welded to the circuit board 13.
