A cable connector

Abstract

This utility model relates to a cable connector, comprising an inner shell and an outer shell, the outer shell being fitted onto the inner shell. The inner shell has multiple through holes, each containing a conductive head. A peripheral wall is formed on the side of the inner shell that accommodates the outer shell, and a sealing ring is provided on this peripheral wall. Positioning blocks are also distributed on the peripheral wall to position the sealing ring. A cavity is formed within the outer shell for fitting with the inner shell, and a protrusion is formed on the inner wall of this cavity. The protrusion and the positioning block are located on the same side of the peripheral wall, and the inner side of the protrusion abuts against the sealing ring. This utility model solves the misalignment problem by using the positioning block and the protrusion to double-fix the sealing ring; it features an anti-detachment structure: an inclined guide surface guides the self-locking latch, simplifying the assembly process; and a modular design: a snap-fit ​​cable connector allows for quick assembly and disassembly.

Description

Technical Field

[0001] This utility model relates to the field of electronic connector technology, and in particular to a cable connector with high sealing performance and anti-detachment structure. Background Technology

[0002] Existing cable connectors are prone to water leakage and dust intrusion in complex environments due to insufficient sealing, and the locking structure is susceptible to loosening due to vibration. Traditional solutions suffer from unstable sealing ring positioning and complex anti-loosening mechanisms, affecting assembly efficiency and reliability. Therefore, there is an urgent need for a connector structure that combines efficient sealing with stable locking. Summary of the Invention

[0003] This utility model provides a cable connector that improves sealing performance and connection stability through a nested design of an inner shell and an outer shell, combined with a sealing ring positioning structure and a self-locking anti-detachment mechanism.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A cable connector, characterized in that it includes an inner shell and an outer shell, the outer shell being sleeved on the inner shell, the inner shell having a plurality of through holes, each through hole having a conductive head disposed therein, the inner shell having a peripheral wall on one side for sleeved on the outer shell, a sealing ring being disposed on the peripheral wall, and positioning blocks being distributed on the peripheral wall for positioning the sealing ring, the outer shell having a cavity for sleeved on the inner shell, the inner wall of the cavity having a protrusion, the protrusion and the positioning block being located on the same side of the peripheral wall, and the inner side of the protrusion abutting against the sealing ring.

[0006] The present invention further includes an anti-detachment structure formed on the outer walls of the outer shell and the inner shell. The anti-detachment structure includes a latch on the outer wall of the inner shell and a limiting block on the outer wall of the outer shell. Two limiting blocks are arranged opposite each other, with a first space between them for accommodating the latch. Abutment blocks are formed on both sides of the end of the latch. A guide block is formed on the limiting block. The inner wall of the guide block is an inclined surface, and a second space is formed between the guide block and the outer wall of the outer shell for the latch to pass through. When the latch has completely passed through the second space, the abutment block and the guide block limit each other.

[0007] The present invention further includes an inner housing connected to a cable connector, and an outer housing also connected to a cable connector. The inner wall of the connecting part of the cable connector is provided with a fastening block. The portions of the outer housing and the inner housing used to connect with the connecting part form fastening holes, and the fastening block is fitted to the fastening hole.

[0008] The present invention further provides that the inclination angle of the inclined surface is 15°-45°.

[0009] The beneficial effects of this utility model are as follows: Sealing structure: The positioning block and the protruding block form a double-fixed sealing ring, which solves the problem of misalignment; Anti-detachment structure: The inclined guide surface guides the self-locking of the latch, which simplifies the assembly process; Modular design: The snap-fit ​​cable connector enables quick assembly and disassembly.

[0015] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0016] like Figure 1-3 As shown, this utility model is a cable connector, including an inner shell 10 and an outer shell 20. The outer shell 20 is sleeved on the inner shell 10. The inner shell 10 has a plurality of through holes 30, and a conductive head 40 is disposed in each of the through holes 30. The inner shell 10 has a peripheral wall 50 on one side for sleeved on the outer shell 20. A sealing ring 60 is disposed on the peripheral wall 50. Positioning blocks 70 are also distributed on the peripheral wall 50 for positioning the sealing ring 60. The outer shell 20 has a cavity 80 for sleeved on the inner shell 10. A protrusion 90 is formed on the inner wall of the cavity 80. The protrusion 90 and the positioning block 70 are located on the same side of the peripheral wall 50. The inner side of the protrusion 90 abuts against the sealing ring 60.

[0017] The outer walls of the outer shell 20 and the inner shell 10 are provided with an anti-detachment structure. This anti-detachment structure includes a latch 100 on the outer wall of the inner shell 10 and a limiting block 110 on the outer wall of the outer shell 20. Two limiting blocks 110 are arranged opposite each other, with a first space between them for the latch 100. Abutment blocks 120 are formed on both sides of the end of the latch 100. A guide block 130 is formed on the limiting block 110. The inner wall of the guide block 130 is an inclined surface, forming a second space between it and the outer wall of the outer shell 20 for the latch 100 to pass through. The inclination angle of the inclined surface is 15°-45°. When the latch 100 has completely passed through the second space, the abutment block 120 and the guide block 130 mutually limit each other.

[0018] In a further embodiment of this invention, the inner housing 10 is also connected to a cable connector 140, and the outer housing 20 is also connected to a cable connector 140. The inner wall of the connecting part of the cable connector 140 is provided with a fastening block 150. The parts of the outer housing 20 and the inner housing 10 used for connecting with the connecting part form a fastening hole 160. The fastening block 150 is adapted to the fastening hole 160 for installation.
