Detailed Description of the Embodiment

[0032] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0033] First Embodiment:

[0034] Please refer to Figures 1 to 4 , in which Figure 1 is the three-dimensional view of the first embodiment of the present invention, Figure 2 is the schematic internal structure view of the lower cover in the first embodiment of the present invention, Figure 3 is the schematic internal structure view of the fixing sleeve in the first embodiment of the present invention, Figure 4 is the connection schematic view of the cable core in the first embodiment of the present invention.

[0035] The present invention provides a cable quick connector assembly device, including two fixing sleeves 101, an upper cover 102 and a lower cover 103. The inner side of the fixing sleeve 101 has an internal thread 104. The inner bottom of the lower cover 103 is provided with two lifting seats 105 and two connecting seats 106. The lifting seat 105 has a plurality of cable grooves 107 inside, and the connecting seat 106 has a plurality of connecting grooves 108 inside. A conductive connecting piece 109 is arranged between the two connecting grooves 108 corresponding to the two connecting seats 106. Both the upper cover 102 and the lower cover 103 have two inlet holes 110 inside. Both ends of the upper cover 102 and the lower cover 103 have external threads 111. The upper cover 102 and the lower cover 103 are in contact with each other and cover the upper part of the lower cover 103. The two fixing sleeves 101 are respectively threadedly sleeved on both ends of the upper cover 102 and the lower cover 103, and the internal thread 104 is located at the external thread 111. By matching the internal thread 104 on the inner side of the fixing sleeve 101 with the external threads 111 at both ends of the upper cover 102 and the lower cover 103, the stable assembly of the device is realized. The upper cover 102 and the lower cover 103 are in contact with each other and cover each other to form a shell for protecting the internal cable core 113 and the connection structure. This design not only improves the assembly efficiency of the connector, but also ensures the stability and durability of the connector, facilitating quick and reliable cable connection in complex environments. The connecting grooves 108 in the connecting seat 106 and the arranged conductive connecting piece 109 ensure reliable electrical connection between multiple cable cores 113.

[0036] Among them, the two lifting seats 105 are symmetrically arranged on the inner bottom of the lower cover 103 respectively, the two connecting seats 106 are symmetrically arranged on the inner bottom of the lower cover 103 respectively, and the two connecting seats 106 are also located between the two lifting seats 105. Through this symmetrical layout, not only the structural symmetry of the connector is enhanced, the overall stability is improved, but also the cable core 113 can be evenly stressed during the connection process, avoiding connection looseness or damage caused by uneven stress. At the same time, the symmetrical design also facilitates the insertion and fixation of the cable core 113, improving the usability of the connector.

[0037] Secondly, an insulating plate 112 is also arranged on the inner bottom of the lower cover 103, and a plurality of conductive connecting pieces 109 are fixedly connected to the insulating plate 112 and located above the insulating plate 112. The insulating plate 112 effectively isolates the direct contact between the conductive connecting piece 109 and the external environment, preventing safety accidents caused by electrical short circuit or electric leakage. In addition, the insulating plate 112 also plays a role in supporting and fixing the conductive connecting piece 109, enhancing the stability and reliability of the connector.

[0038] When using a cable quick connector assembly device according to this embodiment, the insulation layers of two cables are stripped off by using a wire stripper to expose the stranded cable cores 113, and the stranded cable cores 113 are arranged into a bundle; one of the cables with the insulation layer stripped off is inserted through the inlet hole 110 at one end of the lower cover 103, so that the cable cores 113 can correctly fall into the cable slot 107 of the lifting seat 105, and at the same time, the part of the cable cores 113 that needs to be connected abuts against the connection slot 108 of the connection seat 106; then, according to the above operation, the other cable is placed into the inlet hole 110 at the other end of the lower cover 103. At this time, the conductive connection piece 109 will connect the cable cores 113 of the two cables; then the upper cover 102 is covered on the lower cover 103, and finally the two fixing sleeves 101 are respectively threadedly sleeved on the two ends of the upper cover 102 and the lower cover 103 and rotated to a tightened state.

[0039] Second Embodiment:

[0040] Based on the first embodiment, please refer to Figures 5 to 10 , wherein Figure 5 is the front view of the second embodiment of the present invention, Figure 6 is of the present invention Figure 5 the sectional view taken along line A-A in Figure 7 is of the present invention Figure 5 the sectional view taken along line B-B in Figure 8 is the structural schematic diagram of the upper cover in the second embodiment of the present invention, Figure 9 is the structural schematic diagram of the lower cover in the second embodiment of the present invention, Figure 10 is the structural schematic diagram of the fixing sleeve in the second embodiment of the present invention.

[0041] The present invention provides a cable quick connector assembly device. Two C-shaped sealing strips 201 are arranged at the outer edge of the upper cover 102, and two C-shaped grooves 202 are formed at the outer edge of the lower cover 103, and the C-shaped sealing strips 201 abut against the C-shaped grooves 202. Semi-circular grooves 203 are formed at both ends of the upper cover 102 and the lower cover 103. Circular sealing strips 204 are arranged on the inner sides of the two fixing sleeves 101, and the circular sealing strips 204 abut against the semi-circular grooves 203. Through the cooperation of the C-shaped sealing strips 201 and the C-shaped grooves 202, and the cooperation of the semi-circular grooves 203 and the circular sealing strips 204, a multi-directional sealing structure is formed. This design not only improves the waterproof and dustproof performance of the connector, but also enhances the sealing performance and durability of the connector. When used in a harsh environment, it can effectively prevent moisture, dust and other sundries from entering the connector, ensuring the stability and safety of cable connection.

[0042] Among them, a plurality of positioning posts 205 are provided at the inner edge of the upper cover 102, a plurality of positioning grooves 206 are provided at the inner edge of the lower cover 103, and the positioning posts 205 are located in the positioning grooves 206. Through the cooperation of the positioning posts 205 and the positioning grooves 206, precise positioning of the upper cover 102 and the lower cover 103 during the assembly process is achieved. This design not only simplifies the assembly process of the joint, improves the assembly efficiency, but also ensures the tightness and stability of the upper cover 102 and the lower cover 103 after being closed.
