After the first connector 401 is inserted into the housing 1, the conductive wire 7 extending out of the first connector 401 enters the wire clamping opening 303 of the wire clamping assembly 3 through the first wire through hole 2017; after the second connector 401 is inserted into the housing 1, the conductive wire 7 extending out of the second connector 401 enters the wire clamping opening 303 of the wire clamping assembly 3 through the second wire through hole 2026. The conductive wires 7 of the first connector 401 and the second connector 401 are respectively inserted at both ends of the housing 1 and connected to the same wire clamping assembly 3 to achieve circuit connection. The first receiving space 2014 and the second receiving space 2024 together accommodate the wire clamping assembly 3.

[0026] In this embodiment, as Figure 1 , Figure 6 , Figure 8 and Figure 10 As shown, the first locking member 201 has two first wire-passing holes 2017 and two first receiving spaces 2014. One first wire-passing hole 2017 communicates with one first receiving space 2014, and the other first wire-passing hole 2017 communicates with the other first receiving space 2014. The two first wire-passing holes 2017 and the two first receiving spaces 2014 are not connected. The second locking member 202 has two first wire-passing holes 2017 and two second receiving spaces 2024.

The first locking member 201 and the second locking member 202 together accommodate two wire clamping assemblies 3, allowing two conductive wires 7 to enter from both ends of the housing 1.

[0027] In one embodiment, such as Figure 1 , Figure 5 , Figure 11 , Figure 12 and Figure 13 As shown, the wire clamping assembly 3 includes a wire clamping plate 301. The wire clamping plate 301 includes a first wire clamping side plate portion 3011, a second wire clamping side plate portion 3012, a first wire clamping bottom plate portion 3013, and a second wire clamping bottom plate portion 3014. The first wire clamping side plate portion 3011 and the second wire clamping side plate portion 3012 are correspondingly arranged. The first wire clamping bottom plate portion 3013 is fixedly connected to the first wire clamping side plate portion 3011 and the second wire clamping side plate portion 3012 respectively. The second wire clamping bottom plate portion 3014 is fixedly connected to the first wire clamping side plate portion 3011 and the second wire clamping side plate portion 3012 respectively. The first wire clamping bottom plate portion 3013 and the second wire clamping bottom plate portion 3014 are spaced apart.

The ends of the first wire clamping side plate portion 3011 and the second wire clamping side plate portion 3012 form wire clamping openings 303, so that the conductive wire 7 enters through the wire clamping openings 303 into the corresponding spaces of the first wire clamping side plate portion 3011 and the second wire clamping side plate portion 3012.

[0028] In one embodiment, such as Figure 1 , Figure 5 , Figure 11 , Figure 12 and Figure 13As shown, the outer wall 3018 of the first wire clamping side plate portion 3011 and the outer wall 3018 of the second wire clamping side plate portion 3012 are respectively provided with protruding positioning portions 3016. The wire clamping end 3017 of each end of the first wire clamping side plate portion 3011 is bent toward the second wire clamping side plate portion 3012, and the wire clamping end 3017 of each end of the second wire clamping side plate portion 3012 is bent toward the first wire clamping side plate portion 3011. The width of the wire clamping opening 303 is smaller than the width between the first intermediate connecting section of the first wire clamping side plate portion 3011 and the second intermediate connecting section of the second wire clamping side plate portion 3012. Through the bending arrangement, the width of the wire clamping opening 303 in the Y-axis direction is smaller than the width between the first intermediate connecting section and the second intermediate connecting section of the second wire clamping side plate portion 3012, so as to generate a clamping force on the conductive wire 7 entering the wire clamping opening 303.

The elastic bottom plate portion 3023 is connected to the first elastic side plate portion 3021 and the second elastic side plate portion 3022 respectively. The inner sidewall of the first elastic side plate portion 3021 is connected to the first wire clamping side plate portion 3011. The outer side wall 3018 is fitted together, and the inner side wall of the second elastic side plate portion 3022 is fitted together with the outer side wall 3018 of the second clamping wire side plate portion 3012. The first elastic side plate portion 3021 and the second elastic side plate portion 3022 are respectively provided with positioning holes 3024, and the positioning holes 3024 are correspondingly provided with the protruding positioning portion 3016.

Simultaneously, through the engagement of the positioning hole 3024 and the positioning protrusion, the inner side wall of the elastic side plate portion is fitted to the outer side wall 3018 of the wire clamping side plate portion, and the elastic clamping plate 302 exerts an elastic force on the wire clamping plate 301. It should be noted that the two ends of the first elastic side plate portion 3021 and the second elastic side plate portion 3022 are bent and adapted to the bent portions of the wire clamping plate 301.

[0031] In one embodiment, such as Figure 1 , Figure 3 , Figure 16 As shown, it also includes a first sealing ring 5. The outer peripheral surface of the first sealing ring 5 is fitted to the inner peripheral wall of the housing 1. One side wall of the first sealing ring 5 abuts against the third abutting end face 104 or the fourth abutting end face 105 of the connecting channel. One first sealing ring 5 corresponds to one plug-in component 4. Figure 1 As shown, there are two first sealing rings 5. The side wall of one first sealing ring 5 abuts against the third abutting end face 104, and the side wall of the other sealing ring abuts against the fourth abutting end face 105. The outer peripheral surface of the first sealing ring 5 is slightly larger than the inner peripheral wall of the housing 1 to achieve a sealing effect.

The outer circumferential surface of the second sealing ring 402 is slightly larger than the inner circumferential wall of the housing 1. On the one hand, the second sealing ring 402 and the first sealing ring 5 play a double sealing role. On the other hand, the second sealing ring 402 can also prevent the connectors 401 from being driven outward when they are subjected to an outward driving force, so as to ensure the stability of clamping the conductive wire 7.

[0033] In one embodiment, such as Figure 1 , Figure 4 , Figure 14 and Figure 15 As shown, the outer peripheral wall of the connector 401 is provided with a connector protrusion 4012, and the housing 1 is provided with a connector hole 106. The connector protrusion 4012 and the connector hole 106 are correspondingly arranged. The arrangement of the connector protrusion 4012 and the connector hole 106 realizes the connector 401 and the housing 1 for plugging connection, so as to stabilize the connector 401.

[0034] In this embodiment, the component 6 to be inserted is also included. The component to be inserted has an exposed conductive wire 7. The component to be inserted 6 and the connector 401 are fixedly connected. This embodiment does not limit the fixed connection method, and it can be one of the following methods: welding, bonding, insertion, etc.

[0035] A method of using an electrical connector includes the following steps: (1) The wire clamping assembly 3, the locking assembly 2, the two first sealing rings 5, and the housing 1 are assembled in the factory respectively; (2) During the on-site construction process, in the connected state, the on-site personnel fix the second sealing ring 402, the workpiece 6 to be inserted and the plug 401, so that the conductive wire 7 extends out of the plug 401, and the housing 1 is connected to the plug 401 at both ends, so that the conductive wire 7 enters the wire clamping opening 303 through the first wire hole 2017 or the second wire hole 2026 to realize the connection of the circuit.

[0036] It should be noted that the electrical connector of this application will be designed in a series of different specifications and sizes to accommodate conductive wires 7 of different diameters in actual use, thereby ensuring that the conductive wires 7 can be smoothly connected to the wire clamping opening 303 of the electrical connector.

[0037] The electrical connector provided by this utility model has the following advantages: (1) In a vibrating environment (e.g., at the side of a train track), by snapping the plug 401 to the housing 1 and connecting the locking component 2 to the housing 1, and clamping the conductive wire 7 with the wire clamping opening 303, a triple vibration-resistant connection is achieved, ensuring the stability of the connection between the plug component 4 and the housing 1, improving the vibration resistance performance, and preventing the problem of power failure due to the separation of the conductive wire 7 from the wire clamping opening 303; (2) By setting the first sealing ring 5 and the second sealing ring 402 at one end of the housing 1, external moisture is prevented from entering the housing 1 in cold and humid environments; (3) The locking component 2 and the housing 1, the plug component 4 and the housing 1, the plug component 4 and the locking component, and the locking component 2 and the wire clamping component 3 are all detachable connections, requiring no special tools, reducing maintenance costs, and the high versatility of the parts allows for replacement between parts, resulting in high reliability and suitability for harsh environments.
