Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a power cable connector. Background Art

[0002] Cable is an electrical energy or signal transmission device, usually composed of several or several groups of wires. Cable connection generally refers to the intermediate connection and terminal connection of various cables in the cable line. It is indispensable in the power transmission network. The cable is mainly connected according to the characteristics of the cable structure. It can not only restore the performance of the cable, but also ensure the extension of the cable length and the connection of the terminal. When connecting the cables, power cable connectors are required for connection.

[0003] According to a power cable connector disclosed in a Chinese patent, the patent number CN218828220U4 proposes that when in use, the connector male seat can be inserted into the connector female seat. After the connector male seat is inserted into the connector female seat, the compression spring will push the limit pin to embed into the limit groove, thereby ensuring the strength of the connection. At the same time, the adjustment ring can be rotated during use. After rotating the adjustment ring, the sliding support foot will drive the first slide plate to move forward and backward, thereby adjusting the length of the compression spring, and then adjusting the pressure of the limit pin on the connector male seat, which can not only ensure the strength of the connection, but also prevent the connector from being separated from the cable after being strongly pulled.

[0004] The above-mentioned existing power cable connector needs to be accurately connected during docking, which leads to inaccurate connection and the need for multiple connections, thus causing inconvenience to the connection work of the staff. At the same time, the power cable connector in the above description is only supported by two elastic pins, which leads to the connection strength of the power cable connector being insufficient to support the pulling force of the cable during use. Therefore, the existing power cable connector needs to be improved. Utility Model Content

[0026] At this time, the pressing column 3 is released and the spring 5 is used to make the pressing column 3 rebound upward, so that the upward rebound of the pressing column 3 squeezes and fixes the ball 12;

[0027] The connecting cylinder 10 is slidably connected to the inner wall of the female base 7, and the concave terminal 15 is arranged on the inner wall of the female base 7;

[0028] Then, the connecting tube 10 is inserted into the inner wall of the female seat 7, so that the male seat 4 and the female seat 7 form a snap connection;

[0029] The ball 12 is engaged with the inner wall of the slot 9, and the ball 12 is slidably connected to the outer wall of the V-shaped slot 13. There are several balls 12, and the balls 12 are arranged at equal distances on the outer wall of the pressing column 3.

[0030] The pressing column 3 is pressed downward to shrink the ball 12 into the V-shaped groove 13 . The pressing column 3 is released to squeeze the ball 12 into the spherical hole 11 , so that the ball 12 is engaged in the groove 9 .

[0031] By setting the structures such as the pressing column 3, the spring 5 and the connecting tube 10, the pressing column 3 is pressed downward to press the ball 12 into the inside of the female seat 7. At this time, the pressing column 3 is released and rebounds upward through the spring 5, so that the ball 12 is engaged with the inner wall of the slot 9.

[0032] This enables the staff to quickly and conveniently connect the cables, thereby improving the working efficiency of the power cable connector. Due to the annular arrangement of the ball 12, the connection stability of the power cable connector is enhanced.

[0033] See also Figure 1-5 The utility model provides a technical solution: a power cable connector, including a cable conductor 1, a sealing component 2 is arranged on the outer wall of the cable conductor 1, and a pressing column 3 is fixedly installed on one side of the sealing component 2, a heat dissipation ring 8 is fixedly installed inside the female seat 7, a convex terminal 14 is arranged on the inner wall of the pressing column 3, and a concave terminal 15 is connected to the outer wall of the convex terminal 14, and a sealing component 2 16 is arranged on the outer wall of the cable conductor 1;

[0034] The pressing column 3 is slidably connected to the inner wall of the connecting tube 10, and the male seat 4 is extruded and connected with the female seat 7 through the sealing ring 6;

[0035] When the power cable connector is connected, the male seat 4 squeezes the sealing ring 6, so that the power cable connector is sealed;

[0036] The sealing component 1 2 includes a threaded cover 201, and the inner wall of the threaded cover 201 is threadedly connected with a shrink ring 202, and the inner wall of the shrink ring 202 is fixedly connected with a rubber ring 203. The internal structure of the sealing component 2 16 is consistent with that of the sealing component 1 2;

[0037] At this time, the threaded cover 201 is rotated to drive the shrink ring 202 to shrink, so that the shrink ring 202 shrinks inward to squeeze the rubber ring 203, thereby locking the rubber ring 203 on the outer wall of the cable conductor 1, and at the same time, the sealing component 16 is turned to lock the other section of the cable conductor 1 in the same way;

[0038] The two cable conductors 1 are fixedly installed with the male terminal 14 and the female terminal 15 respectively by bolts, and the cable conductors 1 are installed by the male terminal 14 and the female terminal 15 being engaged with each other;

[0039] At this time, the ends of the two cable conductors 1 are fixedly connected inside the male terminal 14 and the female terminal 15 respectively, and the male terminal 14 is also engaged and connected with the female terminal 15 at the same time.

[0040] By setting the sealing component 1 2, the sealing ring 6 and the heat dissipation ring 8, and by using the sealing component 1 2 and the sealing component 2 16, the outer wall gaps of the two cable conductors 1 are sealed, and the use of the sealing ring 6 will seal the gap between the male socket 4 and the female socket 7;

[0041] The power cable connector is thus fully sealed, and the heat accumulated inside the cable connection is dissipated by the provision of the heat dissipation ring 8, thereby ensuring the stability of the cable connection and increasing the practicality of the power cable connector.

[0042] Working principle: When using the power cable connector, the ends of the two cable conductors 1 are fixedly connected to the inside of the convex terminal 14 and the concave terminal 15 respectively, so that the pressing column 3 is pressed downward to shrink the ball 12 into the V-shaped groove 13, and then the connecting tube 10 is inserted into the inner wall of the female seat 7. At this time, the pressing column 3 is released and the spring 5 is used to make the pressing column 3 rebound upward, so that the upward rebound of the pressing column 3 squeezes and fixes the ball 12, and then the ball 12 is squeezed and fixed in the spherical hole 11, so that the ball 12 is engaged in the slot 9, so that the male seat 4 and the female seat 7 form an engaging connection, and at the same time, the convex terminal 14 will also be engaged and connected with the concave terminal 15, so that the power cable connector can quickly and firmly connect the cable.

[0043] When the power cable connector completes the connection of the cable, the threaded cover 201 is rotated to drive the shrink ring 202 to shrink, so that the inward contraction of the shrink ring 202 will squeeze the rubber ring 203, and then the rubber ring 203 is locked to the outer wall of the cable conductor 1, and the sealing component 2 16 is turned to lock the other section of the cable conductor 1 in the same way, thereby completing the sealing of the two ends of the power cable connector. When the power cable connector is connected, the male seat 4 squeezes the sealing ring 6 to seal the middle section of the power cable connector, and the heat accumulated at the cable connection is dissipated through the use of the heat dissipation ring 8.
