Description

Technical Field

[0001] This utility model relates to the field of automotive parts switch technology, and in particular to a switch module. Background Technology

[0002] In the automotive parts industry, the switch module is a key component for controlling the on / off state of vehicle circuits. The rationality of its structural design and the maintainability of its function are crucial to the stable operation of the equipment. The outer shell of the switch module is equipped with a connecting sleeve, one end of which is inserted into the lead wire in the circuit board and the other end is plugged into the plug, thereby realizing the current conduction between the lead wire and the plug.

[0003] In existing switch module designs, the connecting sleeve and the housing cover are often made using an integrated injection molding process, which makes it impossible to replace the connecting sleeve separately. During plug-in use, if the connecting sleeve is deformed or damaged due to long-term use or overload, it cannot be replaced separately because it is integrally molded with the cover. Instead, the entire housing cover must be replaced.

[0004] Therefore, how to improve the structural design of the switch module so that it can be disassembled and replaced separately when the connecting sleeve is damaged, avoiding the wasteful operation of replacing the entire outer cover, is an urgent problem to be solved. Utility Model Content

[0005] The purpose of this invention is to provide a switch module to solve the problems mentioned in the background art.

A connecting sleeve for assisting the lead wire of the switch body is inserted through the side of the cover plate.

[0009] A locking assembly is provided for fixing the insertion point of the connecting sleeve and the cover plate. The locking assembly includes a long bolt, the end of which is inserted into the side of the cover plate. The end of the long bolt is provided with a fixing part for locking and fixing the connecting sleeve. The insertion point of the long bolt and the cover plate is provided with an anti-loosening part for preventing the long bolt from rotating.

[0010] Preferably, the fixing part includes a fixing protrusion, which is disposed at the end of the long bolt, and the side of the fixing protrusion is inserted and connected to the side of the connecting sleeve.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] This utility model provides, for example Figure 1-7 As shown:

[0033] Example 1,

[0034] A switch module includes: a switch body 1, a closing component, and a locking component 4;

[0035] It should be noted that the switch body 1 is used in the field of automotive parts switches, and the sealing assembly is used for the sealing connection of the switch body 1. The sealing assembly includes a cover plate 2 disposed on the back of the switch body 1, and a snap-fit ​​part for fixing the cover plate 2 is provided at the connection between the switch body 1 and the cover plate 2. A connecting sleeve 3 for assisting the lead wire of the switch body 1 is inserted through the side of the cover plate 2.

[0036] Specifically, the locking component 4 is used to fix the insertion point of the connecting sleeve 3 and the cover plate 2. The cover plate 2 is made of plastic. The connecting sleeve 3 is used for the insertion connection of the wiring terminal. The side of the cover plate 2 is provided with a through hole for the connecting sleeve 3 to pass through.

[0037] It should be noted that the locking component 4 includes a long bolt 401, the end of which is inserted into the side of the cover plate 2. The end of the long bolt 401 is provided with a fixing part for snapping and fixing the connecting sleeve 3. The insertion point between the long bolt 401 and the cover plate 2 is provided with an anti-loosening part to prevent the long bolt 401 from rotating.

[0038] Specifically, the cover plate 2 has threaded holes on its side for the long bolt 401 to pass through, and the fixing part includes a fixing protrusion 402. The fixing protrusion 402 is disposed at the end of the long bolt 401, and the side of the fixing protrusion 402 is inserted and connected to the side of the connecting sleeve 3.

[0039] It should be noted that a fixing groove 301 is provided on the side of the connecting sleeve 3. The fixing groove 301 is used to fix the rotating insertion of the fixing protrusion 402. The fixing protrusion 402 is set as a semi-circle and is used to fix the rotating engagement of the fixing groove 301.

[0040] Specifically, the fixing protrusion 402 is welded and fixed to the long bolt 401. During the installation of the connecting sleeve 3, the long bolt 401 is rotated first so that the fixing protrusion 402 does not obstruct the insertion of the connecting sleeve 3 into the cover plate 2. The fixing protrusion 402 is rotated and inserted into the fixing groove 301, thereby fixing the position of the connecting sleeve 3.

[0041] Specifically, the snap-fit ​​part includes: a snap-fit ​​slot block 101 and a snap-fit ​​strip block 201;

[0042] It should be noted that multiple slot blocks 101 are symmetrically arranged on the side of the switch body 1, and multiple strip blocks 201 are symmetrically arranged on the side of the cover plate 2.

[0043] Specifically, the clip block 201 is used to clip and fix the slot block 101. The side of the clip block 201 is interlocked with the side of the slot block 101, thereby fixing the cover plate 2 to the switch body 1.

[0044] Example 2,

[0045] An anti-loosening part is applied to the switch module in Embodiment 1;

[0046] Specifically, the anti-loosening part includes: a pressure ring 403 and a compression spring 404;

[0047] It should be noted that the pressure ring 403 is sleeved on the outside of the long bolt 401, and the compression spring 404 is sleeved on the outside of the long bolt 401 and located on the side of the pressure ring 403 closer to the switch body 1.

[0048] Specifically, the pressure ring 403 and the long bolt 401 are fixed by welding. Under the push of the compression spring 404, the outer thread of the long bolt 401 is in close contact with the thread of the threaded hole, which increases the friction at the engagement point and prevents the long bolt 401 from loosening.

[0049] It should be noted that a movable groove is provided at the intersection of the long bolt 401 and the cover plate 2. The compression spring 404 and the pressure ring 403 are set in the inner cavity of the movable groove. A sealing block 405 is provided at the end of the long bolt 401. The sealing block 405 is used to seal and isolate the end of the long bolt 401. The sealing block 405 is made of rubber and is glued to the end of the long bolt 401.

[0050] In actual use, by setting a cover plate 2 with a snap-fit ​​part on the back of the switch body 1, the long bolt 401 in the locking assembly 4 drives the fixing part at its end to fix the connecting sleeve 3 that is inserted into the cover plate 2. Compared with the integral injection molding of the connecting sleeve 3 and the cover plate 2, this design allows for the separate disassembly and replacement of the damaged connecting sleeve 3, avoiding the wasteful operation of replacing the damaged connecting sleeve 3 and the cover plate 2 as a whole.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
