DETAILED DESCRIPTION

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1:

[0023] See also Figure 1-8 The utility model provides a technical solution: a cable joint connector with a waterproof function, comprising a first connecting tube 100, a second connecting tube 101 is provided on the upper side of the first connecting tube 100, the first connecting tube 100 is fixedly connected to two front-to-back symmetrical orifice plates 102, the second connecting tube 101 is fixedly connected to two front-to-back symmetrical slot plates 103, the slot plates 103 and the orifice plates 102 are aligned up and down, and two front-to-back symmetrical rubber strips 113 are fixedly connected to the upper end surface of the first connecting tube 100, and two front-to-back symmetrical sealing grooves 116 are provided in the second connecting tube 101, the rubber strips 113 are stuck in the sealing grooves 116, so that after the first connecting tube 100 and the second connecting tube 101 are fixedly connected through the orifice plates 102 and the slot plates 103, the sealing grooves 116 can ensure the sealing of the joint between the first connecting tube 100 and the second connecting tube 101.

[0024] Example 2:

[0025] See also Figure 1-8 In order to ensure the sealing of the seam between the cable and the connector, a wiring tube 104, a second rubber ring 114 and a first rubber ring 107 are provided;

[0026] The left and right end surfaces of the first connecting tube 100 and the second connecting tube 101 are both sealed and fixedly connected to the wiring tube 104. A first rubber ring 107 is fixedly connected to the wiring tube 104 of the first connecting tube 100. The first rubber ring 107 has a protruding piece. A second rubber ring 114 is fixedly connected to the wiring tube 104 of the second connecting tube 101. The second rubber ring 114 is located in the wiring tube 104 and has a slot 117. The first rubber ring 107 can be snapped into the slot 117. Furthermore, the inner diameters of the first rubber ring 107 and the second rubber ring 114 are slightly smaller than the inner diameter of the wiring tube 104 . Thus, by inserting the first rubber ring 107 into the slot 117 and then fixing the first connecting tube 100 and the second connecting tube 101 together, the second rubber ring 114 and the first rubber ring 107 can be tightly attached to the cable passing through the wiring tube 104 , thereby ensuring the sealing of the joints between the cable and the wiring tube 104 and between the two wiring tubes 104 and preventing water seepage.

[0027] Example 3:

[0028] See also Figure 1-8 , in order to facilitate the installation and removal of the entire connector, a hole plate 102, a slot plate 103 and a connecting plate 105 are provided;

[0029] Each of the orifice plates 102 is provided with a plurality of equally spaced through holes 112, and each of the slot plates 103 is provided with a threaded groove 115 coaxially aligned with each of the through holes 112. A bolt 118 passes through the through holes 112 and is screwed into the threaded groove 115, thereby fixedly connecting the orifice plate 102 and the slot plate 103, and further fixedly connecting the first connecting pipe 100 and the second connecting pipe 101.

[0030] The two second connecting tubes 101 on the same side of the first connecting tube 100 and the second connecting tube 101 are symmetrical in vertical direction, and the wiring tubes 104 are fixedly connected to two symmetrical connecting plates 105 in front and back. The two connecting plates 105 can be tightly attached to each other, and screws 119 are passed through the connecting plates 105 and then threadedly connected with nuts 120 to further fix the two wiring tubes 104 and ensure the sealing of the connector.

[0031] The cable 106 can be inserted between the first connecting tube 100 and the second connecting tube 101 from the left and right sides to connect the cables.

[0032] Working principle:

[0033] First, after connecting the two cables 106, place the first connecting tube 100 on the lower side, with the connection point of the cables 106 located at the center of the first connecting tube 100. Then align the second connecting tube 101 vertically with the first connecting tube 100 and place it on the upper side of the cables 106. Pass the bolt 118 through the through hole 112 and screw it into the thread groove 115 to securely connect the first connecting tube 100 and the second connecting tube 101. At the same time, the rubber strip 113 will be stuck in the sealing groove 116. The rubber strip 113 ensures the sealing of the joint between the first connecting tube 100 and the second connecting tube 101, thereby preventing water leakage at the joint between the first connecting tube 100 and the second connecting tube 101.

[0034] When the first connecting tube 100 and the second connecting tube 101 are connected, the protruding portion of the first rubber ring 107 is inserted into the card slot 117, and the screw 119 is threadedly connected to the nut 120 after passing through the connecting plate 105, thereby fixing the two wiring tubes 104. The second rubber ring 114, which has an inner diameter slightly smaller than that of the wiring tube 104, and the first rubber ring 107 are in close contact with the outer surface of the cable 106, ensuring the sealing of the connection between the cable 106 and the wiring tube 104 and the seam of the wiring tube 104, thereby facilitating assembly and disassembly while ensuring good waterproof performance of the entire connector.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
