[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0038] The embodiments of this utility model will be described below based on its overall structure.
[0039] First embodiment:
[0040] A quick-connect cable connector, as shown in Figures 1-6, includes a first cable 1 and a second cable 2. The first cable 1 and the second cable 2 are provided with a mutually cooperating electrical connection structure. Specifically, a corresponding conductive hole is provided at the plug 201 of the second cable 2 along the conductive metal wire inside the cable, and a conductive post corresponding to the conductive hole is provided in the socket 101 of the first cable.
[0041] It also includes a first retaining ring 102 and a second retaining ring 203. After the first cable 1 and the second cable 2 are inserted into each other, the first retaining ring 102 and the second retaining ring 203 form an annular groove corresponding to each other. The first cable 1 and the second cable 2 are connected in opposite directions along the radial direction of the cable at the annular groove. The diameter of the retaining ring structure between the first cable 1 and the second cable 2 is smaller than the diameter of the first cable 1 and the second cable 2.
[0042] In the above embodiment, please refer to Figures 3-6 for details. The end of the first cable 1 facing the second cable 2 is provided with a recessed socket 101 along the axial direction. The end of the second cable 2 facing the first cable 1 is provided with a plug 201 for inserting into the socket 101. The electrical connection between the two cable segments is achieved by connecting the plug 201 and the socket 101.
[0043] Specifically, the electrical connection between the two cables is achieved by connecting the plug 201 and the socket 101. After the plug plate 202 is inserted into the socket 101 of the first cable, the stability of the connection between the two cables can be further improved.
[0044] In the above embodiment, please refer to Figures 3-6 for details. The first cable 1 and the second cable 2 are provided with a sealing sleeve 3 that fits into the annular groove. The sealing sleeve 3 can ensure the sealing between the two cable segments. Specifically, the sealing sleeve 3 is an elastic sealing rubber ring that fits into the annular groove. When the two cable segments are connected to each other, the sealing sleeve 3 is first put on the outer wall of the second cable 2, and then moved to the position of the annular groove after the first cable 1 and the second cable 2 are inserted into each other.
[0045] Furthermore, the first cable 1 and the second cable 2 are engaged with a first retaining ring 4 and a second retaining ring 5 at the annular groove, thereby securing the first cable 1 and the second cable 2 together.
[0046] Specifically, the first retaining ring 4 and the second retaining ring 5 are connected to each other by screws. The screws can easily and quickly connect the first retaining ring 4 and the second retaining ring 5, and can also quickly disconnect the two sections of cable when needed.
[0047] Second embodiment:
[0048] A quick-connect cable connector, as shown in Figures 1-6, has the centers of the first retaining ring 102 and the second retaining ring 203 recessed towards the axes of the first cable 1 and the second cable 2, respectively. The inwardly recessed annular structure can further improve the stability of the retaining ring connection, and also improve the stability when the two cable segments are connected.
[0049] Specifically, a heat-shrinkable sleeve 6 is fitted at the connection between the first cable 1 and the second cable 2. The heat-shrinkable sleeve 6 can further improve the sealing of the cable connection. When connecting the two cable segments, the heat-shrinkable sleeve 6 is first fitted onto the outer wall of the first cable 1. After the retaining ring structure between the first cable 1 and the second cable 2 is connected, the heat-shrinkable sleeve 6 is moved to the connection between the first cable 1 and the second cable 2. The specific method of heating the heat-shrinkable sleeve 6 is a mature existing technology, which will not be described in detail here.
[0050] Furthermore, two insert plates 202 are spaced apart along the circumference and are set 180 degrees apart on the circumferential surface, so that the two insert plates 202 are inserted separately into the socket 101 of the first cable 1. Two first retaining rings 102 are spaced apart along the circumference and are set 180 degrees apart on the circumferential surface. The two first retaining rings 102 and the two second retaining rings 203 together form a complete ring. The insertion of the insert plates 202 into the socket 101 also serves as a guide to prevent the wires in the plug 201 from deviating from the electrical connection hole.
[0051] In practical operation, the following steps are taken: Align the insert plate 202 with the socket 101 and insert the first cable 1 and the second cable 2 in opposite directions. After the first retaining ring 102 and the second retaining ring 203 form a complete annular groove, the sealing sleeve 3 is fitted on. Then, along the radial direction of the cable, the first retaining ring 4 and the second retaining ring 5 are fitted into the annular groove and screws are used to fix the first retaining ring 4 and the second retaining ring 5 to each other. Finally, the heat shrink sleeve is fitted on the connection between the two cable sections and heated.
