When assembling the cable, the end of the cable can be clamped in the third strip groove 32 and contacted with the other end of the Z-shaped conductive rod 24 for electrical connection.

[0019] Among them, both sides of the positioning plate 20 are fixed on the bottom plate 10 through positioning bolts 21. When it is necessary to assemble the Z-shaped conductive rod 24, first align the Z-shaped conductive rod 24 with the second strip groove 23 on the lower surface of the positioning plate 20, and then fix the positioning plate 20 on the bottom plate 10 through the positioning screw 21, while ensuring that one end of the Z-shaped conductive rod 24 is in interference fit with the positioning cavity.

The cable avoidance hole is in interference fit with the cable. When wiring, the cable can pass through the cable avoidance hole and extend to the Z-shaped conductive rod 24 to contact the end of the Z-shaped conductive rod 24 for electrical connection.

[0021] Among them, a locking end cover 41 is provided at the rear end of the pressing plate 40. The locking end cover 41 covers the third strip plate 31. The locking end cover 41 is used to lock the cable in the third strip groove 32. After the cable is connected, the front end of the pressing plate 40 presses the connection between the front cable and the Z-shaped conductive rod 24, and the locking end cover 41 presses the connection between the rear cable and the Z-shaped conductive rod 24, thereby increasing the sealing performance of the connection between the cable and the Z-shaped conductive rod 24, preventing water mist from entering the connector, improving the waterproof effect, avoiding affecting the service life of the connector, and facilitating use.

[0022] Among them, the outer side of the pressing plate 40 is surrounded by a housing 50. The front end of the housing 50 is provided with an end limiting plate 51. The end limiting plate 51 wraps the pressing plate 40. After the pressing plate 40 tightly seals the connection between the cable and the Z-shaped conductive rod 24, the housing 50 is surrounded outside the pressing plate 40 to enclose the pressing plate 40. And a rubber sealing ring is provided at the edge when the housing 50 surrounds the pressing plate 40 to increase the sealing performance and prevent external water mist from entering the connector through the joint between the housing 50 and the pressing plate 40, and the end of the pressing plate 40 is wrapped by the end limiting plate 51.

[0023] Among them, first extension plates 53 are provided on both sides of the end of the housing 50. First positioning holes 11 are opened on the surface of the bottom plate 10 corresponding to the positions of the first extension plates 53. The first extension plates 53 are clamped in the first positioning holes 11. When the housing 50 is surrounded outside the pressing plate 40, the first extension plates 53 at the end of the housing 50 are inserted into the first positioning holes 11, thereby positioning the housing 50 on the bottom plate 10.

[0024] Among them, second protrusions 54 are provided on the surface of the first extension plate 53, and first protrusions 52 are provided on one side of the housing 50 close to the first extension plate 53; a locking cover 60 is surrounded outside the housing 50.

Through the cooperation of the second protrusions 54 and the second card slots 63, and the cooperation of the first card slots 62 and the first protrusions 52, the locking cover 60 is clamped outside the housing 50.

[0025] Among them, second extension plates 61 are provided at positions close to the first card slots 62 on both sides of the locking cover 60. Second positioning holes 12 are opened on the surface of the bottom plate 10 corresponding to the positions of the second extension plates 61. The second extension plates 61 are clamped in the second positioning holes 12. When the locking cover 60 is clamped outside the housing 50, the second extension plates 61 are also clamped in the second positioning holes 12, thereby clamping the locking cover 60 and the bottom plate 10 together.

[0026] Wherein, a lower cover plate is provided below the tail end of the outer shell 50, and the front end of the outer shell 50 is hollowed out at the position corresponding to the pressing plate 40. When the outer shell 50 needs to be assembled outside the pressing plate 40, first insert the first extension plate 53 at the end of the outer shell 50 into the first positioning hole 11, so as to snap the outer shell 50 onto the bottom plate 10 and make the outer shell 50 enclose the pressing plate 40. Then assemble the lower cover plate at the tail end of the outer shell 50 to wrap the support plate 30. Then cover the locking cover 60 on the outer shell 50 and snap the second extension plate 61 into the second positioning hole 12, so as to snap the locking cover 60 onto the bottom plate 10. When the second extension plate 61 is snapped into the second positioning hole 12, the second protrusion 54 is snapped together with the second card slot 63, and the first card slot 62 is snapped together with the first protrusion 52, so as to snap the locking cover 60 outside the outer shell 50, achieving the purpose of locking the outer shell 50.

[0027] Furthermore, to ensure the normal snapping and covering of the locking cover 60 and the outer shell 50, both the locking cover 60 and the outer shell 50 are made of PC plastic. Wherein, the bottom plate 10, the positioning plate 20, the support plate 30, and the pressing plate 40 are also made of PC plastic.

[0028] Wherein, positioning posts are provided at the bottom of the front end of the pressing plate 40, and mounting holes 15 are provided on the surface of the bottom plate 10 at the positions corresponding to the positioning posts. The pressing plate 40 is mounted on the bottom plate 10 through the cooperation of the positioning posts and the mounting holes 15, and the pressing plate 40 is pressed on the positioning plate 20. The pressing plate 40 is mounted on the bottom plate 10 through the cooperation of the positioning posts and the mounting holes 15, and then the pressing plate 40 is locked on the bottom plate 10 through the outer shell 50 and the locking cover 60 without using bolts, which is convenient for later disassembly or assembly.

[0029] Wherein, a support plate 33 is provided at the tail of the positioning plate 20. The support plate 33 is located below the support plate 30, and the support plate 33 is used to support the support plate 30. By supporting the support plate 30 with the support plate 33, it is ensured that the support plate 30 is in a horizontal state on the positioning plate 20.

[0030] Working principle: Through the cooperation of the positioning plate 20 and the bottom plate 10, one end of the Z-shaped conductive rod 24 is locked and positioned in the positioning cavity. When wiring, the cable can extend through the cable avoidance hole to the Z-shaped conductive rod 24 and contact the end of the Z-shaped conductive rod 24 for electrical connection; the end of the cable is clamped in the third strip-shaped groove 32 and contacts the other end of the Z-shaped conductive rod 24 for electrical connection; after the cable is connected, the front end of the pressure plate 40 presses the connection between the front-end cable and the Z-shaped conductive rod 24, and the locking end cover 41 presses the connection between the rear-end cable and the Z-shaped conductive rod 24, thereby increasing the sealing performance of the connection between the cable and the Z-shaped conductive rod 24. Then, the pressure plate 40 is locked on the bottom plate 10 through the outer shell 50 and the locking cover 60, thereby increasing the sealing performance of the connection between the cable and the Z-shaped conductive rod 24, preventing water mist from entering the connector, improving the waterproof effect, avoiding affecting the service life of the connector, and facilitating use; During specific wiring, the locking cover 60 is removed from the outer shell 50, then the outer shell 50 is removed from the pressure plate 40. Then, the pressure plate 40 is no longer restricted and can be removed. Next, the end of one cable can be clamped in the first strip-shaped groove 14 and contact the front end of the Z-shaped conductive rod 24 for electrical connection. The end of the other cable can be clamped in the second strip-shaped groove 32 and contact the tail of the Z-shaped conductive rod 24 for electrical connection. Then, the pressure plate 40 is installed on the bottom plate 10 through the cooperation of the positioning post and the mounting hole 15, and the pressure plate 40 is pressed on the positioning plate 20. The front end of the pressure plate 40 presses the connection between the front-end cable and the Z-shaped conductive rod 24, and the locking end cover 41 presses the connection between the rear-end cable and the Z-shaped conductive rod 24, thereby increasing the sealing performance of the connection between the cable and the Z-shaped conductive rod 24, preventing water mist from entering the connector, improving the waterproof effect, avoiding affecting the service life of the connector, and facilitating use. Then, the first extension plate 53 at the end of the outer shell 50 is inserted into the first positioning hole 11, thereby clamping the outer shell 50 on the bottom plate 10 and surrounding the pressure plate 40 with the outer shell 50. Then, the lower cover plate at the tail end of the outer shell 50 is assembled at the tail end of the outer shell 50, thereby wrapping the support plate 30. Then, the locking cover 60 is covered on the outer shell 50, and the second extension plate 61 is clamped in the second positioning hole 12, thereby clamping the locking cover 60 on the bottom plate 10. When the second extension plate 61 is clamped in the second positioning hole 12, the second protrusion 54 is clamped with the second card slot 63, and the first card slot 62 is clamped with the first protrusion 52, thereby clamping the locking cover 60 outside the outer shell 50 to lock the outer shell 50. The pressure plate 40 is locked on the bottom plate 10 through the outer shell 50 and the locking cover 60, thereby increasing the sealing performance of the connection between the cable and the Z-shaped conductive rod 24.

[0032] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
