Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a cable connector. Background Technology

[0002] In the fields of electrical connections, cable connectors, as key connection components, are widely used in communication equipment, servers, consumer electronics, and industrial equipment. The main function of cable connectors is to achieve stable and reliable electrical connection and signal transmission between cables and ports. In related technologies, current cable connectors typically use claws to clamp the cable to prevent it from falling off due to external pulling, thus ensuring the durability of the connection. For example, in patent document CN117317687A, multiple elastic claws are set on the cable clamp, the cable clamp and the housing are separable structures, and during assembly, the cable is passed through the end cap and the cable clamp, so that the cable clamp holds the cable, and the cable assembly is snapped onto the housing through the end cap.

[0003] Therefore, the separate design of the claws requires the claws to be aligned with the cable and fixed to the housing during the assembly process. The assembly operation is complicated and affects the assembly efficiency. In addition, there is a certain tolerance between the claws and the housing, which leads to insufficient reliability of the connector and cable connection. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this utility model is to provide a cable connector, comprising: The outer casing has an integrally formed wire locking claw at one end. The wire locking claws are spaced apart around the central axis of the outer casing, and when the outer peripheral surface of the wire locking claws is squeezed by force, the wire locking claws close together relative to the central axis. A plug-in assembly is located at the other end of the housing and is detachably connected to the housing; A fastener is fitted onto the wire locking claw and threadedly connected to the housing. When the fastener is threadedly fixed to the housing, the fastener applies force to press the wire locking claw so that the wire locking claws close together.

[0005] Preferably, the locking claw includes a plurality of claw plates, which are deformable along the radial or circumferential direction of the outer casing.

[0006] Preferably, each of the claws has two sides formed as inclined surfaces, which gradually slope from the outer side to the inner side of the claw.

[0007] Preferably, the inner circumferential surface of the fastener includes a threaded section and a pressing section connected to each other, the threaded section being adjacent to the locking claw and the pressing section being away from the locking claw.

[0008] Preferably, the extrusion section is configured as a tapered structure and gradually increases in size toward the locking claw.

[0009] Preferably, the housing further includes: A receiving body, the receiving body being configured to gradually increase in size from a first end to a second end; An external thread portion is provided at the first end of the receiving body and is located between the locking claw and the receiving body.

[0010] Preferably, the receiving body has an internal thread, and the internal thread is located at the second end of the receiving body.

[0011] Preferably, the plug-in assembly includes: A connector, the first end of which is connected to the housing; An operating component is sleeved on the second end of the connecting component and is rotatably connected to the connecting component. A contact metal element is disposed within the connector and extends from one end of the connector to the other end.

[0012] Preferably, a first sealing ring is fitted at the first end of the connector, and a second sealing ring is fitted at the second end of the connector. The first sealing ring is used to seal the gap between the connector and the housing, and the second sealing ring is used to seal the gap between the connector and the operating component.

[0013] Preferably, the outer shell is a nylon shell.

[0014] The above-described solution of this utility model has at least the following beneficial effects: The cable connector provided by this utility model uses an integrally formed locking claw on the housing. When assembling the cable, the cable can pass through the fastener and extend into the locking claw. The fastener is then threaded to the housing, allowing the fastener to apply force to compress the locking claw, causing the locking claw to close together and thus securing the cable. This simplifies the assembly operation between the cable and the connector, increases assembly efficiency, avoids tolerances between the claw and the housing, and improves the reliability of the connector and cable connection.

[0024] The cable connector of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0025] Reference Figures 1 to 3As shown, the cable connector provided in this embodiment of the present invention includes: a housing 10, a plug-in assembly 20, and a fastener 30. One end of the housing 10 has an integrally formed locking claw 11, which is spaced around the central axis of the housing 10. When the outer circumferential surface of the locking claw 11 is pressed by force, the locking claw 11 closes with each other relative to the central axis. The plug-in assembly 20 is disposed at the other end of the housing 10 and is detachably connected to the housing 10. The fastener 30 is sleeved on the locking claw 11 and threadedly connected to the housing 10. When the fastener 30 is threadedly fixed to the housing 10, the fastener 30 applies force to press the locking claw 11 so that the locking claw 11 closes with each other.

[0026] Among them, the outer shell 10 is a nylon outer shell 10. Using nylon material for the outer shell 10 can make the rigidity and toughness of the locking claw 11 more balanced, and can ensure better overall wear resistance.

[0027] Reference Figure 3 and Figure 4 As shown, when assembling the cable and connector, the cable can pass through the fastener 30 and extend into the housing 10, connecting with the plug-in assembly 20. This allows the cable to be located within the locking claw 11 while extending into the housing 10. When the fastener 30 is tightened, the locking claw 11 has several claws 111 that can deform along the radial or circumferential direction of the housing 10. When the outer side of each claw 111 is squeezed by the fastener 30, each claw 111 deforms and contracts inward, thus allowing each claw 111 to clamp and fix the cable together, ensuring a tighter assembly of the cable within the housing 10 and simplifying the assembly operation.

[0028] It is understood that the outer casing 10 also includes: a receiving body 12 and an external threaded portion 13. The external threaded portion 13 is located at the first end of the receiving body 12 and between the locking claw 11 and the receiving body 12. The inner circumferential surface of the fastener 30 includes a threaded section 31 and a pressing section 32 connected to each other. The threaded section 31 is adjacent to the locking claw 11. When the fastener 30 is threadedly fixed to the outer casing 10, the threaded section 31 is threadedly fixed to the external threaded portion 13, so that the fastener 30 can move axially toward the receiving body 12 when the thread rotates, and drive the pressing section 32 to gradually abut against the locking claw 11. Since the pressing section 32 is configured as a conical structure and gradually increases toward the locking claw 11, after the pressing section 32 gets closer to the locking claw 11, the smaller diameter of the pressing section 32 further presses the locking claw 11, causing the locking claw 11 to be deformed and locked onto the outer circumferential surface of the cable, thereby ensuring that the cable is locked more tightly and reliably.

[0029] As a preferred method, each claw 111 has two sides formed as inclined surfaces 112, which gradually slope from the outside to the inside of the claw 111, so that when the claws 111 close together, the two adjacent inclined surfaces 112 are pressed together, which can make the gap of the locking claws 11 retract smaller and the locking effect of the cable better.

[0030] Reference Figure 3 and Figure 5 As shown, the receiving body 12 is configured to gradually increase in size from the first end to the second end, and the receiving body 12 has an internal thread 121 located at the second end of the receiving body 12. Further, the insertion assembly 20 includes a connector 21, an operating member 22, and a contact metal member 23. The first end of the connector 21 is connected to the housing 10, and the connector 21 can be threadedly fixed to the internal thread 121 of the receiving body 12, ensuring a tighter connection between the connector 21 and the housing 10. The connector 21 can be inserted into a device port, and the operating member 22 is sleeved on the second end of the connector 21, and... The connectors 21 are rotatably connected, and the operating member 22 can also be threaded so that when the connector 21 is inserted into the device port, it can be fixed to the device port by the threaded connection of the operating member 22, ensuring a more stable insertion of the connector 21. It can be understood that the contact metal member 23 is located inside the connector 21 and extends from one end of the connector 21 to the other end. The cable extends into the housing 10 and can be tightened and fixed to one end of the contact metal member 23 with a screw, so that when the connector 21 is connected to the device port, the other end of the contact metal member 23 can be electrically connected to the metal plug inside the device port, ensuring a more reliable electrical contact of the connector.

[0031] Preferably, a first sealing ring 24 is fitted on the first end of the connector 21, and a second sealing ring 25 is fitted on the second end of the connector 21. The first sealing ring 24 is used to seal the gap between the connector 21 and the housing 10, and the second sealing ring 25 is used to seal the gap between the connector 21 and the operating member 22. This ensures better overall sealing of the connector and prevents moisture from entering when applied to different scenarios, resulting in better waterproof and dustproof performance.

[0032] The cable connector provided by this utility model uses an integrally formed locking claw 11 on the housing 10. When assembling the cable, the cable can pass through the fastener 30 and extend into the locking claw 11. The fastener 30 is then threadedly fixed to the housing 10. When the fastener 30 is threaded, it can apply force to squeeze the locking claw 11, causing the locking claw 11 to close together and thus clamping and fixing the cable. This makes the assembly operation between the cable and the connector simpler, the assembly efficiency higher, and avoids tolerance between the claw and the housing, thereby improving the reliability of the connection between the connector and the cable.
