[0030] See also Figure 1-Figure 5, the present application provides a connector installation and disassembly structure, the connector includes a base 14, a fixed base 11 and a C-shaped retaining spring 12, the top of the fixed base 11 is provided with a C-shaped retaining spring 12, the bottom of the fixed base 11 is provided with a base 14, the end of the base 14 away from the fixed base 11 is connected to a wire 15, and the end of the C-shaped retaining spring 12 away from the fixed base 11 is provided with a connector; the outer diameter of the fixed base 11 is less than or equal to the outer diameter of the base 14, and a notch is provided in the C-shaped retaining spring 12. When the C-shaped retaining spring 12 is not compressed, the outer diameter of the C-shaped retaining spring 12 is greater than the outer diameter of the fixed base 11, and when the C-shaped retaining spring 12 is compressed, the outer diameter of the C-shaped retaining spring 12 is less than or equal to the outer diameter of the fixed base 11;

[0031] The installation and disassembly structure includes a handle 31 and an extrusion head 32 , and the inner diameter of the extrusion head 32 is smaller than or equal to the outer diameter of the fixing seat 11 .

[0032] When the connector needs to be disassembled, the extrusion head 32 is nested on the outside of the C-shaped retaining spring 12 from one side of the connector 13, so that the C-shaped retaining spring 12 is compressed. Since a notch is provided in the C-shaped retaining spring 12, the outer diameter of the C-shaped retaining spring 12 becomes smaller after compression, and since the inner diameter of the extrusion head 32 is less than or equal to the outer diameter of the fixing seat 11, when the C-shaped retaining spring 12 is compressed by the extrusion head 32, the side where the C-shaped retaining spring 12 is located can be removed from the mounting through hole by external force, thereby realizing the disassembly of the connector.

[0033] When the connector needs to be installed, the extrusion head 32 is nested on the outside of the C-shaped retaining spring 12 from the side of the wire 15, so that the C-shaped retaining spring 12 is compressed, and the plug 13 and the C-shaped retaining spring 12 are passed through the connecting through hole. The C-shaped retaining spring 12 after passing through the connecting through hole is stretched to achieve the clamping connection with the installation through hole. The extrusion head 32 of the present application cooperates with the retractable C-shaped retaining spring 12 to realize the installation and removal of the connector, improves the installation and removal efficiency of the connector, and does not cause damage to the surface and interior of the connector.

[0034] Example 2

[0035] See also Figure 1-Figure 5, the present application provides a connector installation and disassembly structure, the connector includes a base 14, a fixed base 11 and a C-shaped retaining spring 12, the top of the fixed base 11 is provided with a C-shaped retaining spring 12, the bottom of the fixed base 11 is provided with a base 14, the end of the base 14 away from the fixed base 11 is connected to a wire 15, and the end of the C-shaped retaining spring 12 away from the fixed base 11 is provided with a connector; the outer diameter of the fixed base 11 is less than or equal to the outer diameter of the base 14, and a notch is provided in the C-shaped retaining spring 12. When the C-shaped retaining spring 12 is not compressed, the outer diameter of the C-shaped retaining spring 12 is greater than the outer diameter of the fixed base 11, and when the C-shaped retaining spring 12 is compressed, the outer diameter of the C-shaped retaining spring 12 is less than or equal to the outer diameter of the fixed base 11; the installation and disassembly structure includes a handle 31 and an extrusion head 32, and the inner diameter of the extrusion head 32 is less than or equal to the outer diameter of the fixed base 11.

[0036] Furthermore, a first guide position 22 is provided at the top of the mounting through hole, and the inner diameter of the first guide position 22 gradually increases from the bottom to the top of the mounting through hole. That is to say, the mounting through hole is a through hole structure provided on the mounting plate 21, and a first guide position 22 with an inner diameter gradually increasing from bottom to top is provided at the top of the mounting through hole. The present application defines the top of the mounting through hole as the side where the connector 13 is located after the connector is installed. The bottom of the mounting through hole is defined as the side where the wire 15 is located after the connector is installed. When the connector is installed in the mounting plate 21, the fixing seat 11 is located in the mounting through hole, the base 14 is located below the mounting plate 21, and the connector and the C-shaped retaining ring 12 are located above the mounting plate 21.

[0037] Correspondingly, a first guide arc 121 is disposed at one end of the C-shaped retaining ring 12 close to the fixing seat 11 , and the outer diameter of the first guide arc 121 gradually increases in the direction of the line from the fixing seat 11 to the C-shaped retaining ring 12 .

[0038] The first guide arc 121 corresponds to the first guide position 22. When the connector needs to be disassembled, the extrusion head 32 is nested on the outside of the C-shaped retaining spring 12 from one side of the plug connector 13, so that the C-shaped retaining spring 12 is compressed. Since the C-shaped retaining spring 12 is provided with a notch, the outer diameter of the compressed C-shaped retaining spring 12 becomes smaller, and since the inner diameter of the extrusion head 32 is less than or equal to the outer diameter of the fixing seat 11, after the C-shaped retaining spring 12 is compressed by the extrusion head 32, the first guide arc 121 at the bottom of the C-shaped retaining spring 12 moves downward along the first guide position 22, and the side where the C-shaped retaining spring 12 is located can be disassembled from the mounting through hole by external force, so as to realize the disassembly of the connector. The external force here refers to the downward force applied to the connector under the mounting plate 21, so that the connector is pulled out of the mounting through hole.

[0039] Furthermore, a second guide position is provided at the bottom of the mounting through hole, and the inner diameter of the second guide position gradually decreases from the bottom to the top of the mounting through hole. The second guide position is arranged opposite to the first guide position 22, and is respectively located at the top and bottom of the mounting through hole, and both are structures that expand outward relative to the center of the mounting through hole.

[0040] Correspondingly, a second guide arc 122 is provided at one end of the C-shaped retaining ring 12 away from the fixing seat 11 , and the outer diameter of the second guide arc 122 gradually decreases in the direction of the line from the fixing seat 11 to the C-shaped retaining ring 12 .

[0041] When the connector needs to be installed, the extrusion head 32 is nested on the outside of the C-shaped retaining spring 12 from the side of the wire 15, so that the C-shaped retaining spring 12 is compressed. Since there is a notch in the C-shaped retaining spring 12, the outer diameter of the compressed C-shaped retaining spring 12 becomes smaller, and since the inner diameter of the extrusion head 32 is less than or equal to the outer diameter of the fixing seat 11, after the C-shaped retaining spring 12 is compressed by the extrusion head 32, the second guide arc 122 at the top of the C-shaped retaining spring 12 moves upward along the second guide position, and the side where the C-shaped retaining spring 12 is located can be penetrated through the installation through hole by external force, so as to realize the removal of the connector. The external force here refers to the upward force applied to the connector above the mounting plate 21, so that the connector is pulled out of the mounting through hole.

[0042] The side of the extrusion head 32 described in the present application is provided with a notch, and the height of the notch is greater than the sum of the heights of the plug connector 13 and the C-shaped retaining ring 12. The notch is provided to facilitate observation of the position and condition of the C-shaped retaining ring 12 inside the extrusion head 32. When the extrusion head 32 disassembles the connector, the extrusion head 32 needs to penetrate from the top of the connector, that is, the side of the plug connector 13, until it is clamped to the outside of the C-shaped retaining ring 12. Therefore, the height of the extrusion head 32 is required to be high enough to accommodate the plug connector 13.

[0043] The inner diameter of the bottom end of the extrusion head 32 is less than or equal to the outer diameter of the fixing seat 11, and the inner diameter of the top end of the extrusion head 32 is greater than the inner diameter of the bottom end. When disassembling the connector, the bottom end of the extrusion head 32 is used to clamp the C-shaped retaining spring 12. Since the outer diameter of the C-shaped retaining spring 12 can be changed, the outer diameters of the parts of the connector other than the C-shaped retaining spring 12 are fixed. And in the process of disassembling and installing the connector, it is the bottom of the extrusion head 32, that is, the side of the extrusion head 32 away from the handle 31 that clamps the C-shaped retaining spring 12. Therefore, the bottom of the extrusion head 32 can be set to have an inner diameter less than or equal to the outer diameter of the fixing seat 11 to ensure that it compresses the C-shaped retaining spring 12, so that the C-shaped retaining spring 12 can pass through the installation through hole, and the position at the top of the extrusion head 32 to accommodate other parts can be set to a structure with a larger outer diameter. Figure 4As shown, the outer diameter of the extrusion head 32 can be increased from bottom to top to prevent the extrusion head 32 from interfering with other connector parts except the C-shaped retaining spring 12.

[0044] In order to better accommodate the plug 13 or the wire 15 in the connector, the extrusion head 32 is a hollow chamber, and the handle 31 is arranged perpendicular to the extrusion head 32. In the present application, the extrusion head 32 can be made of a rigid material to ensure that the inner diameter of the extrusion head 32 is always maintained at a size less than or equal to the outer diameter of the fixing seat 11.

[0045] The working principle of the present application is as follows: when the connector needs to be disassembled, the extrusion head 32 is nested on the outside of the C-shaped retaining spring 12 from one side of the plug 13. At this time, the plug and the C-shaped retaining spring 12 are located inside the hollow chamber of the extrusion head 32, and the bottom of the extrusion head 32 is clamped with the C-shaped retaining spring 12, and the top of the extrusion head 32 accommodates the plug 13. Since the outer diameter of the bottom of the extrusion head 32 is less than or equal to the outer diameter of the mounting through hole, the extrusion head 32 nested on the outside of the C-shaped retaining spring 12 causes the C-shaped retaining spring 12 to be compressed. Since the C-shaped retaining spring 12 is provided with a notch, the outer diameter of the compressed C-shaped retaining spring 12 becomes smaller until it is less than or equal to the outer diameter of the fixing seat 11. After the C-shaped retaining spring 12 is compressed by the extrusion head 32, the first guide arc 121 at the bottom of the C-shaped retaining spring 12 moves downward along the first guide position 22, and the side where the C-shaped retaining spring 12 is located can be removed from the mounting through hole by external force, thereby realizing the disassembly of the connector. The external force here refers to a downward force applied to the connector below the mounting plate 21, so that the connector is pulled out from the mounting through hole.

[0046] When the connector needs to be installed, the extrusion head 32 is nested on the outside of the C-shaped retaining spring 12 from the side of the wire 15. At this time, the wire 15 and the C-shaped retaining spring 12 are located inside the hollow chamber of the extrusion head 32, and the bottom of the extrusion head 32 is clamped with the C-shaped retaining spring 12, and the top of the extrusion head 32 accommodates the wire 15, etc. Since the outer diameter of the bottom of the extrusion head 32 is less than or equal to the outer diameter of the installation through hole, the extrusion head 32 nested on the outside of the C-shaped retaining spring 12 compresses the C-shaped retaining spring 12, and since the notch is provided in the C-shaped retaining spring 12, the outer diameter of the compressed C-shaped retaining spring 12 becomes smaller until it is less than or equal to the outer diameter of the fixing seat 11. After the C-shaped retaining spring 12 is compressed by the extrusion head 32, the second guide arc 122 at the top of the C-shaped retaining spring 12 moves upward along the second guide position, and the side where the C-shaped retaining spring 12 is located can be penetrated through the installation through hole by external force to realize the disassembly of the connector. The external force here refers to an upward force applied to the connector above the mounting plate 21, so that the connector is pulled out from the mounting through hole.

[0047] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should belong to the scope covered by the claims of the utility model.
