Description

Technical Field

[0001] This utility model relates to a connector and a connector assembly including the connector. Background Technology

[0002] In existing technology, Type-C connectors typically include a connector for connecting to a cable and a mating connector for connecting to a circuit board. The connector mates with the mating connector to achieve a quick electrical connection between the cable and the circuit board. In existing technology, connectors typically include a housing and an electrical connection module inserted into the housing. The electrical connection module includes mating ends for mating with the mating connector, which extend from the front end of the housing and are inserted into the mating housing of the mating connector. The connector's electrical connection module typically includes an insulator located at its mating ends, two rows of terminals disposed within the insulator, and a shielding shell fitted onto the insulator. In existing technology, because the mating ends of the connector's electrical connection module extend from the housing, these mating ends are susceptible to impact during packaging and transportation, which can lead to damage and failure of the mating ends. Furthermore, because the mating ends of the connector's electrical connection module extend from the housing, the connector's vibration resistance is poor, and unstable electrical contact is prone to occur in vibrating environments.

[0039] like Figures 1 to 8 As shown, in an exemplary embodiment of the present invention, a connector 1 is disclosed. 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 opposite each other in its longitudinal direction Y. The electrical connection module 10 is inserted into the housing 18 from the rear port.

[0040] like Figures 1 to 8 As shown in the illustrated embodiment, the front end of the housing 18 extends beyond the mating end 10a of the electrical connection module 10, so that the mating end 10a of the electrical connection module 10 is completely hidden in the front port 181 of the housing 18. Therefore, the mating end 10a of the electrical connection module 10 can be effectively prevented from being impacted during packaging and transportation, and the vibration resistance of the connector 1 can be improved.

The resilient cantilever 121 is located in the mating end 10a of the electrical connection module 10 and is used for electrical contact with the mating terminal 22 on the mating plug 21 inserted into the insertion cavity 110.

[0042] like Figures 1 to 8As shown in the illustrated embodiment, a support wall 111b is formed in the front end of the terminal slot 111, spaced apart from the bottom surface 111a of the terminal slot 111. The support wall 111b is used to apply a certain pre-pressure to the free end 12b of the elastic cantilever 121 before the connector 1 mates with the mating connector 2, thereby increasing the contact pressure between the elastic cantilever 121 and the mating terminal 22. In the illustrated embodiment, the contact pressure between the elastic cantilever 121 and the mating terminal 22 can be increased by at least the aforementioned pre-pressure.

[0043] like Figures 1 to 8 As shown in the illustrated embodiment, the resilient cantilever 121 includes a V-shaped arm 120 and a contact portion 12c.

[0044] like Figures 1 to 8 As shown in the illustrated embodiment, before connector 1 mates with mating connector 2, the free end 12b of the elastic cantilever 121 is supported on the support wall 111b. After connector 1 mates with mating connector 2, the free end 12b of the elastic cantilever 121 separates from the support wall 111b and is supported on the bottom surface 111a of the terminal slot 111. This further increases the contact pressure between the elastic cantilever 121 and the mating terminal 22.

[0045] like Figures 1 to 8 As shown, in the illustrated embodiment, the contact portion 12c of the elastic cantilever 121 is arc-shaped and protrudes into the insertion cavity 110 to make electrical contact with the mating terminal 22 on the mating plug 21 inserted into the insertion cavity 110. The front end of the V-arm 120 is connected to the contact portion 12c, and the rear end of the V-arm 120 is fixed to the insulator 11.

[0046] like Figures 1 to 8 As shown in the illustrated embodiment, the electrical connection module 10 includes two rows of terminals 12 spaced apart and opposite to each other in the height direction Z of the housing 18. The upper row of terminals 12 is used to make electrical contact with a row of mating terminals 22 on the top surface of the inserted mating plug 21, and the lower row of terminals 12 is used to make electrical contact with a row of mating terminals 22 on the bottom surface of the inserted mating plug 21.

[0047] like Figures 1 to 8As shown, in the illustrated embodiment, the electrical connection module 10 further includes a circuit board 13. A row of first solder pads (not shown) is formed on the front and back sides of the front end of the circuit board 13. The rear ends of the upper row of terminals 12 extend from the rear ends of the insulator 11 and are soldered to a row of first solder pads on the front side of the circuit board 13. The rear ends of the lower row of terminals 12 extend from the rear ends of the insulator 11 and are soldered to a row of first solder pads on the back side of the circuit board 13.

[0048] like Figures 1 to 8 As shown in the illustrated embodiment, a plurality of second solder pads (not shown) are formed on the front side of the rear end of the circuit board 13. Each second solder pad is electrically connected to a corresponding first solder pad via a conductive trace (not shown) on the circuit board 13. The electrical connection module 10 also includes a flat cable 14 having a plurality of core wires (not shown). The front ends of the plurality of core wires of the flat cable 14 are respectively soldered to the plurality of second solder pads of the circuit board 13.

In the illustrated embodiment, the rear shielding shell 16 includes two upper and lower half-shielding shells assembled together.

[0051] like Figures 1 to 8 As shown, in the illustrated embodiment, the rear shield 16 has a crimp portion 161 located at its rear end, which is crimped onto the shielding layer 141 of the flat cable 14.

[0052] like Figures 1 to 8 As shown in the illustrated embodiment, a first recess 16a is formed on the top wall of the rear shield 16, and the first recess 16a is soldered to the shielding 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 on the bottom wall of the rear shield 16, and the second recess 16b is soldered to the circuit board 13. This improves the grounding shielding effect of the connector.

[0053] like Figures 1 to 8As shown, in the illustrated embodiment, an outwardly protruding protrusion 16c is formed on the top and / or bottom wall of the rear shield 16, the protrusion 16c being adapted to engage with the housing 18 to lock the electrical connection module 10 in the housing 18.

[0054] like Figures 1 to 8 As shown, in the illustrated embodiment, the connector also includes a heat-shrink tail sleeve 19, which is fitted and heat-shrinked onto the front end of the flat cable 14 and the rear end of the housing 18 for securing the electrical connection module 10 to the housing 18 and the rear port of the sealed housing 18.

[0055] like Figures 1 to 8 As shown in the illustrated embodiment, the aforementioned connector 1 and mating connector 2 are Type-C connectors.

[0056] like Figures 1 to 8 As shown, in another exemplary embodiment of this utility model, a connector assembly is also disclosed. The connector assembly includes a connector 1 and a mating connector 2. The mating connector 2 mates with the connector 1.

The mating terminals 22 are disposed on the mating plug 21 and are used to make electrical contact with the terminals 12 of the connector.

[0058] like Figures 1 to 8 As shown in the illustrated embodiment, the mating housing 28 extends beyond the mating plug 21, so that the mating plug 21 and the mating terminal 22 are completely concealed within the mating housing 28. This prevents the mating plug 21 and the mating terminal 22 from being subjected to impacts during packaging and transportation, and also improves the vibration resistance of the mating connector.

[0059] like Figures 1 to 8 As shown in the illustrated embodiment, the width of the mating terminal 22 of the mating connector 2 is at least 0.1 mm larger than the width of the terminal 12 of the connector 1, and the center line of the terminal 12 coincides with the center line of the mating terminal 22.
