Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a quick-plug cable connector. Background Art

[0002] Cable is a general term for items such as optical cables and electrical cables. Cables have many uses, mainly used for multiple functions such as control installation, connecting equipment, and transmitting power. They are common and indispensable in daily life. Due to the limited length of cables, cable connectors are usually needed to connect two cable segments.

[0003] After searching, the applicant found that a Chinese patent disclosed "a quick-plug cable connector", and its publication (announcement) number is "CN 213425349 U". This patent mainly provides a connector male box, a connector female box, a connecting mechanism, a male connector, a pushing mechanism, a female connector and a connecting needle, so that the device can conveniently install and disassemble two cables, and the connected cables can be reused, which greatly reduces the waste of resources. However, the connector needs to be fixed with bolts. When the bolts age, the efficiency of connector installation and disassembly will be reduced, and its structural stability is low. For this reason, we propose a quick-plug cable connector. Utility Model Content

[0026] Please see the attached Figure 1 -Attached Figure 6The utility model discloses a quick-plug cable connector, including a connector body, which includes a connector bottom box 1, a connector top box 2, and a quick-release assembly 3 for facilitating quick installation and removal of the connector body. A lower fixing box 11 is provided in the middle of the top of the left and right inner walls of the connector bottom box 1. A card slot 12 is provided in the lower fixing box 11. An upper fixing box 21 corresponding to the lower fixing box 11 is provided in the middle of the bottom of the left and right inner walls of the connector top box 2. A rectangular groove 22 is provided at the bottom of the upper fixing box 21. The quick-release assembly 3 is arranged inside the lower fixing box 11 and the upper fixing box 21. The quick-release assembly 3 includes a support column 31, a spring block 1 32, an L-shaped card block 33, and a spring block 2 34.

[0027] The left and right sides of the connector base box 1 are both provided with placement grooves connected to the card slot 12. The inner end of the support column 31 is located in the card slot 12. The top of the inner end of the support column 31 is provided with a wedge-shaped surface 311, and the outer end of the support column 31 is located in the placement groove. The spring block 132 is located outside the outer end of the support column 31, and the inner side of the spring block 132 is fixedly connected to the inner wall of the inner end of the placement groove. The outer side of the spring block 132 is fixedly connected to the outer end of the support column 31. The inner end of the bottom of the card slot 12 is engaged with the bottom end of the L-shaped block 33.

[0028] The top of the L-shaped block 33 slides in contact with the inner wall of the rectangular groove 22, the inner side of the second spring block 34 is fixedly connected to the outer side of the top of the L-shaped block 33, the outer side of the second spring block 34 is fixed to the outer inner wall of the rectangular groove 22, and the elastic force of the second spring block 34 is less than that of the first spring block 32.

[0029] In one embodiment of the present invention, guide holes 13 are provided at the top of each of the four corners of the connector bottom box 1 , and guide posts 23 matching the guide holes 13 are provided at the bottom of each of the four corners of the connector top box 2 .

[0030] In one embodiment of the present invention, two groups of quick-release components 3 are provided, and the two groups of quick-release components 3 are symmetrically arranged on the left and right sides of the connector body.

[0031] In one embodiment of the present invention, a pull block 312 is provided at the outer end of the support column 31 .

[0032] In one embodiment of the present invention, two insulating seats 4 are fixedly connected to the interior of the connector bottom box 1 , and fixing hoops 41 are detachably connected to the tops of the two insulating seats 4 .

[0033] In one embodiment of the present invention, the connector bottom box 1 and the connector top box 2 are symmetrically provided with semicircular openings on the front and rear sides, and a sealing ring is detachably connected to the semicircular openings.

[0034] Example 1, please refer to the attached Figure 1 -Attached Figure 6During the docking process between the connector top box 2 and the connector bottom box 1, after the guide column 23 is inserted into the guide hole 13, the bottom of the L-shaped block 33 is located directly above the wedge-shaped surface 311 of the support column 31. At this time, the crimping top box can be directly pressed downward to facilitate the rapid docking between the connector top box 2 and the connector bottom box 1.

[0035] Example 2, please refer to the attached Figure 1 -Attached Figure 6 The elastic force of spring block 1 32 is greater than the elastic force of spring block 2 34 , which prevents the L-shaped block 33 from being unable to be pushed inward by the pillar 31 when it moves to the bottom of the slot 12 , thereby preventing the L-shaped block 33 from being unable to complete the engagement with the slot 12 .

[0036] Specifically, by setting up the quick-release component 3, when installing the cable and the connector, the connector top box 2 is docked with the connector bottom box 1, and under the squeezing of the anti-pillar 31, the L-shaped card block 33 is clamped inside the card slot 12. When the connector needs to be disassembled, the anti-pillar 31 on both sides of the connector body is pulled outward to disengage the L-shaped card block 33 from the card slot 12. At this time, the connector top box 2 can be directly taken out upwards to complete the disassembly of the connector body, which prevents the aging of the bolts and is conducive to improving the efficiency of installation and disassembly of the connector body.

[0037] Specifically, by providing the guide post 23 and the guide hole 13, during the installation of the connector body, the guide post 23 is inserted into the guide hole 13, which is beneficial to improving the stability of the connector body structure. At the same time, it is convenient for the docking between the quick-release components 3. By providing the insulating seat 4 and the fixing hoop 41, the cable is prevented from being loosened or damaged due to external force, and electrical insulation is maintained between the contact parts of the cable and between the contact parts and the shell.

[0038] Working principle:

[0039] First, connect the two ends of the cable through the contact piece and fix them on the insulating seat 4, then connect the connector top box 2 with the connector bottom box 1, insert the guide column 23 at the bottom of the connector top box 2 into the guide hole 13 at the top of the connector bottom box 1, and then press the connector top box 2 downward. The bottom of the L-shaped block 33 squeezes the column 31 downward, and the column 31 moves outward accordingly. When the guide column 23 is fully inserted into the guide hole 13, the L-shaped block 33 completely enters the card slot 12. At the same time, after the column 31 is no longer squeezed, under the elastic action of the spring block 32, the inner end of the column 31 pushes the L-shaped block 33 inward, so that the L-shaped block 33 is completely engaged in the card slot 12, and the installation of the cable and the connector is completed. When the connector needs to be disassembled, the columns 31 on both sides of the connector body are pulled outward so that the L-shaped card block 33 is not squeezed by the columns 31. At the same time, under the elastic reset action of the spring block 2 34, the L-shaped card block 33 is pulled horizontally, and the L-shaped card block 33 is separated from the card slot 12. At this time, the connector top box 2 can be directly taken out upwards to complete the disassembly of the connector body, which prevents the aging of the bolts in the bolt connection method and is conducive to improving the efficiency of installation and disassembly of the connector body. At this point, the entire work flow is completed.
