DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figures 1 to 4 The utility model provides a technical solution: an inner cone connector that automatically increases interface pressure, comprising an inner cone socket 1, one end of the inner cone socket 1 is provided with a connecting sleeve 3 through a connecting piece, an inner cone cavity 101 is opened inside the inner cone socket 1, and an elastic booster 2 is connected to the inner cone cavity 101 and the connecting sleeve 3 by snapping, the outer wall of the elastic booster 2 facing the inner cone socket 1 is provided with a first cone section 201 that matches the inner wall of the inner cone cavity 101, the outer wall of the elastic booster 2 facing the connecting sleeve 3 is provided with a second cone section 202, the first cone section 201 and the second cone section 202 are in opposite directions and the maximum surface diameter of the first cone section 201 is larger than the maximum surface diameter of the second cone section 202, abutting step 203 is formed at the junction of the first cone section 201 and the second cone section 202, a cone interface 301 that matches the second cone section 202 is provided inside the end of the connecting sleeve 3 facing the elastic booster 2, and the top of the cone interface 301 abuts against the abutting step 203.

[0020] It should be noted that when the inner cone socket 1 and the connecting sleeve 3 are connected in place and the inner diameter of the elastic booster 2 reaches the maximum deformation degree and is still larger than the cable 6, an insulating self-adhesive tape 7 can be wrapped around the corresponding positions of the cable sheathed insulating section 601 and the cable stripped conductive section 602 to increase the diameter of the cable 6, so that the elastic booster 2 can stably boost the cable 6 and reduce limitations in use.

[0021] See also Figure 3 and Figure 4 The elastic booster 2 is made of insulating material and is integrally formed.

[0022] The one-piece molding setting can ensure the overall structural strength while the elastic booster 2 is deformed by the inner cone cavity 101 and the cone interface 301 to apply pressure to the cable 6, thereby avoiding self-fracture that affects the stability of use. The overall insulation can improve safety during use and improve the efficiency of current passage.

[0023] Furthermore, the cone angle of the second cone section 202 is 30°.

[0024] The second conical section 202 is used to increase the pressure on the cable sheath insulation section 601 of the cable 6. When one end of the connecting sleeve 3 abuts against the abutting step 203, the 30° conical surface of the second conical section 202 is completely fitted on the inner wall of the conical interface 301 and is restricted by the conical interface 301 to form a deformation hoop on the outside of the cable sheath insulation section 601 to increase the interface pressure of the cable sheath insulation section 601.

[0025] Furthermore, a connecting plate 302 is provided on the outer wall of the connecting sleeve 3, and the connecting piece includes a positioning hole 303 opened on one side surface of the connecting plate 302, a connecting bolt 5 is inserted in the positioning hole 303, one end of the connecting bolt 5 is threadedly connected to the connecting screw hole 304, and the connecting screw hole 304 is opened on one side surface of the inner cone socket 1 facing the connecting sleeve 3.

[0026] After the cable 6 passes through the connecting sleeve 3 and the elastic booster 2 in sequence and one end of the cable 6 is located in the inner conical cavity 101, the first conical section 201 is located in the inner conical cavity 101, and the second conical section 202 is located in the conical interface 301. The connecting bolt 5 is passed through the positioning hole 303 and threadedly connected to the connecting screw hole 304. By rotating the connecting bolt 5, the inner conical socket 1 and the connecting sleeve 3 are gradually approached. In the process of approaching, the second conical section 202 and the conical interface 301 are gradually fitted. After the top end of the conical interface 301 abuts on the abutting step 203, the first conical section 201 is pushed into the inner conical cavity 101 until the first conical section 2 01 is completely fitted with the inner wall of the inner cone cavity 101. When the inner cone socket 1 and the connecting sleeve 3 are connected in place, the first cone section 201 and the second cone section 202 are respectively restricted by the inner wall of the inner cone cavity 101 and the inner wall of the cone interface 301 to deform to increase the interface pressure of the cable sheathed insulating section 601 and the cable stripped conductive section 602 of the cable 6. When in use, the inner cone socket 1 and the connecting sleeve 3 can also be respectively arranged on both sides of the installation position. When connecting the inner cone socket 1 and the connecting sleeve 3, the connecting bolt 5 can be sequentially passed through the positioning hole 303 and the through hole opened at the installation position and then threadedly connected to the connecting screw hole 304 to reduce limitations in use.

[0027] Furthermore, a protective cover 4 is detachably connected to one end of the connecting sleeve 3 away from the inner cone socket 1 .

[0028] Connecting the protective sleeve 4 at the other end of the connecting sleeve 3 can further protect the connection stability of the cable 6, prevent the cable 6 near the connection from being bent or displaced due to force and affecting the connection effect, and also increase the length of the cable sheath insulation section 601 in the connector, thereby improving safety during use.

[0029] Furthermore, an internal thread 401 is provided on the inner wall of one end of the protective sleeve 4 facing the connecting sleeve 3 , and a thread groove 402 matching with the internal thread 401 is provided on the outer wall of one end of the connecting sleeve 3 facing the protective sleeve 4 .

[0030] The connecting sleeve 3 and the protective sleeve 4 are threadedly connected via the internal thread 401 and the thread groove 402 . The connection is relatively simple and convenient and has high stability, so that the protective sleeve 4 is not easy to fall off and maintains protection for the cable 6 .

[0031] Working principle: Place the elastic booster 2 between the inner cone socket 1 and the connecting sleeve 3, and slightly insert the first cone section 201 into the inner cone cavity 101, and slightly insert the second cone section 202 into the cone interface 301. Pass the cable stripping conductive section 602 of the cable 6 through the connecting sleeve 3 and the elastic booster 2 in sequence and insert it into the inner cone socket 1. At this time, pass the connecting bolt 5 through the positioning hole 303 and thread one end of it into the connecting screw hole 304. By rotating the connecting bolt 5, the inner cone socket 1 and the connecting sleeve 3 can be gradually approached. In the process of approaching, the second cone section 202 and the cone interface 30 1 gradually fits together, and after the top end of the conical interface 301 abuts against the abutting step 203, the first conical section 201 is pushed into the inner conical cavity 101 until the first conical section 201 is completely fitted with the inner wall of the inner conical cavity 101. When the inner conical socket 1 and the connecting sleeve 3 are connected in place, the first conical section 201 and the second conical section 202 are respectively restricted by the inner wall of the inner conical cavity 101 and the conical interface 301 to deform, thereby increasing the interface pressure between the cable sheath insulation section 601 and the cable stripping conductive section 602 of the cable 6, effectively maintaining the interface pressure, eliminating the hidden danger of interface discharge, and improving the stability and reliability of the connector.

[0032] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
