Description

Technical Field

[0001] This utility model relates to the field of high-voltage connector technology, and specifically to a connector socket for electric vehicles. Background Technology

[0002] The high-voltage connector socket in an electric vehicle is a key interface component for realizing power transmission and signal interaction in its high-voltage system. Since electric vehicles will vibrate during driving, the installation stability of the connector socket is very important.

[0003] With the evolving design of electric vehicles and the growing demand for cost savings, some mounting panels are extremely thin. This makes connector socket installation difficult, as they are prone to loosening or even breaking due to vibration. Furthermore, the thinness of the mounting panel makes it susceptible to deformation, compromising the sealing of the connector socket and increasing the risk of leakage. Ensuring the installation stability and reliability of connector sockets is a pressing issue that needs to be addressed. Utility Model Content

[0027] like Figures 1 to 5As shown, this utility model discloses a connector socket for electric vehicles, which is disposed on a thin plate 1 and includes a socket housing 2 and a socket core 3 adapted thereto. The socket housing 2 includes a first flange 201 and a receiving groove. The socket core 3 includes a second flange 301 and a core. The first flange 201 is tightly fitted to the first plate surface 101 of the thin plate 1, and the second flange 301 is tightly fitted to the second plate surface 102 of the thin plate 1. The core passes through the thin plate 1 and is inserted into the receiving groove. A set of bolts 4 are respectively provided along the edges of the first flange 201, the thin plate 1, and the second flange 301 to fix the three together. A sealing layer 304 is provided on the end face of the second flange 301 to seal the gap between the three.

[0028] In this design, the socket housing 2 and the socket inner core 3 are made into a split structure to clamp the thin plate 1 from the first plate surface 101 and the second plate surface 102, respectively. The first flange 201 and the second flange 301 are respectively provided so that the socket housing 2, the socket inner core 3 and the thin plate 1 form a surface contact, thereby increasing the contact area between the three and improving the tightness and stability of the connection between the three. This avoids the problem of weak connection due to the thin plate 1 being too thin. At the same time, a sealing layer 304 is provided to seal the gap between the three and ensure the sealing and reliability of the connection between the three.

[0029] Specific examples Figures 1-5 As shown, the core includes a first terminal group 302 and a second terminal group 303. The receiving groove includes a first receiving groove 202 and a second receiving groove 203. The thin plate 1 is provided with a first through hole 103 and a second through hole 104. The first receiving groove 202 and the first through hole 103 both match the outer contour of the first terminal group 302, and the second receiving groove 203 and the second through hole 104 both match the outer contour of the second terminal group 303. The first terminal group 302 passes through the first through hole 103 and is inserted into the first receiving groove 202, and the second terminal group 303 passes through the second through hole 104 and is inserted into the second receiving groove 203.

[0030] To facilitate the assembly and disassembly of the socket housing 2 and the socket core 3, a set of locking blocks 307 are symmetrically arranged on the outer peripheral wall of the first terminal group 302, and a first latch 205 matching the locking blocks 307 is provided on the inner wall of the first receiving groove 202. The locking blocks 307 engage with the first latch 205 to confine the first terminal group 302 within the first receiving groove 202.

[0031] Similarly, a pair of hooks 308 are symmetrically arranged on the outer wall of the second terminal group 303, and a second latch 206 matching the hooks 308 is provided on the inner wall of the second receiving groove 203. The hooks 308 engage with the second latch 206 to confine the second terminal group 303 within the second receiving groove 203.

[0032] To ensure the sealing performance of the sealing layer 304, a first sealing ring 3041 is provided on the sealing layer 304 along the outer peripheral wall of the first terminal group 302 and a second sealing ring 3042 is provided along the outer peripheral wall of the second terminal group 303. The sealing layer 304 seals the gap between the second flange 301 and the second plate surface 102.

[0033] Furthermore, a third sealing ring 305 is provided around the outer periphery of the first sealing ring 3041 on the sealing layer 304, and a fourth sealing ring 306 is provided around the outer periphery of the second sealing ring 3042. The third sealing ring 305 protrudes outward from the first through hole 103 and abuts against the end face of the first flange 201. The fourth sealing ring 306 protrudes outward from the second through hole 104 and abuts against the end face of the first flange 201. The third sealing ring 305 and the fourth sealing ring 306 seal the gap between the first flange 201, the thin plate 1, and the second flange 301.

[0034] The surfaces of the first sealing ring 3041, the second sealing ring 3042, the third sealing ring 305, and the fourth sealing ring 306 all have multi-level waterproof layers to form a multi-level waterproof structure and ensure sealing performance. The first sealing ring 3041 and the second sealing ring 3042 are disposed on the sealing layer 304 to form a first layer of sealing for the first terminal group 302 and the second terminal group 303. The third sealing ring 305 and the fourth sealing ring 306 are disposed on the sealing layer 304 to form a second layer of sealing for the first terminal group 302 and the second terminal group 303. Simultaneously, the protruding structures of the third sealing ring 305 and the fourth sealing ring 306 seal the connection between the inner core 3 of the socket, the thin plate 1, and the socket outer shell 2, ensuring that the first terminal group 302 and the second terminal group 303 are not affected by the external environment.

[0035] The first terminal group 302 includes two first power terminals 3021 and a pair of first signal terminals 3022. The pair of first signal terminals 3022 are located between the two first power terminals 3021, and the outer ends of the first signal terminals 3022 are lower than the outer ends of the first power terminals 3021. This structure ensures that during the insertion or removal of the connector socket and the mating plug assembly, the connection and removal of the two first power terminals 3021 and the first signal terminals 3022 create a travel difference, ensuring that the two first power terminals 3021 are connected before the first signal terminals 3022 and disconnected after the first signal terminals 3022 are disconnected. This prevents live insertion and removal between the connector socket and the plug assembly, ensuring safe use.

[0036] Furthermore, a safety cap 3023 is provided on the outer end of the first power terminal 3021, and the top of the safety cap 3023 protrudes outward from the top of the first power terminal 3021. The safety cap 3023 is made of a material with good insulation properties to provide a safety function against finger contact.

[0037] Each of the first power terminals 3021 is also equipped with a temperature sensor 3024 that is connected to the inner core to detect the temperature inside the two first power terminals 3021 in real time and ensure safe use.

[0038] The second terminal group 303 includes a mounting base 3033, a set of second power terminals 3031 passing through the mounting base 3033, and a pair of second signal terminals 3032. The outer ends of the second power terminals 3031 are built into the mounting base 3033. The mounting base 3033 within the second terminal group 303 has multiple accommodating cavities to accommodate the second power terminals 3033. In the preferred embodiment illustrated, the mounting base 3033 has four accommodating cavities to accommodate four second power terminals 3033 one by one. In other feasible embodiments, the specific number of accommodating cavities within the mounting base 3033 depends on actual needs and is not limited here.
