Description

Power connector and its support base

This case relates to a power connector, especially a power connector with a support seat to support, hold and fix a plurality of cables with different wire diameters.

Power connectors have been widely used in power networks, power transmission systems, power distribution systems, power supply systems, and electronic equipment as an interface for power transmission and connection. For example, a combination of two power connectors, that is, a combination of a power plug and a power socket, is usually used between a power supply and a power transmission line to achieve electrical connection and power transmission.

In order to support multiple cables with different wire diameters. In other embodiments, the first support parts 83, 93 and the second support parts 84, 94 of the support bases 8, 9 can also be but not limited to arc structures, and through the different heights of the arc structures Correspondingly supports multiple cables with different wire diameters. Therefore, the shape, quantity and arrangement of the first support parts 83 and 93 and the second support parts 84 and 94 of the cable support bases 8 and 9 can be arbitrarily changed according to the actual operation situation, and the first support The shapes of the parts 83 and 93 are not limited to be the same as the second support parts 84 and 94 , and they may also be of different shapes. For example, the first support parts 83 and 93 are two-step stepped structures; , 94 is a three-step ladder structure, or the first support parts 83, 93 are ladder structures, and the second support parts 84, 94 are V-shaped structures, etc., which can be arbitrarily changed according to the actual operation situation, and The implementation form shown in this case is not limited.

In this embodiment, the support bases 8 and 9 can be made of elastic and flexible materials, for example, they can be made of one of plastic material, rubber material, and metal material, but not limited thereto. In addition, it is possible to manufacture the integrally formed support bases 8 and 9 through the injection molding process, but it is not limited to this.

Please refer to Figure 6A ~ Figure 7B at the same time, Figure 6A is a partial schematic view of the cable support seat of the power connector shown in Figure 3 with the front side disposed in the main body. FIG. 6B is a partial schematic view of the cable support base of the power connector shown in FIG. 3 with the reverse side disposed in the main body. FIG. 7A is a schematic diagram of the cable of the power connector shown in FIG. 3 being arranged on the cable support base. FIG. 7B is a schematic diagram of the cross-sectional structure of FIG. 7A. As shown in FIG. 6A, the front of the support base 8 is disposed in the accommodating portion 60 of the main body 6 of the power connector 5, and it is disposed between the second opening 62 and the connector assembly 64, and is adjacent to the In the second opening 62 , in this way, as shown in FIGS. 7A and 7B , after a plurality of cables 4 pass through the second opening 62 , they can correspond to the first support portion 83 disposed across the support base 8 . and the first protruding portion 83a of the first supporting portion 83 can be used to support the first cable 40 with a smaller wire diameter due to its high height, and the second protruding portion 83b with a lower height can be used to support the larger wire diameter Through this auxiliary support, the first cable 40 and the second cable 41 with different wire diameters can obtain sufficient supporting force, and the first cable 40 and the second cable 41 They can be close to each other without slipping. Therefore, when the power cord outer cover 7 is correspondingly disposed on the first opening 61 of the main body 6 as shown in FIG. 4 to close the accommodating portion 60 , and the power cord outer cover 7 is locked to the main body through the locking element 70 6 , the first cable 40 and the second cable 41 can be firmly clamped by the power cable cover 7 and the cable support base 8 to be tightly fitted together.

In addition, if the wire diameter of the first cable 40 is smaller, as shown in FIG. 6B , the cable support base 8 can be disposed in the accommodating portion 60 of the main body 6 of the power connector 5 from the front. , in this way, the second support portion 83 on the reverse side of the cable support base 8 can be used to support the first cable 40 with a smaller wire diameter, that is, the third convex portion 84a with a higher height is used to support the wire. The first cable 40 with a smaller diameter is used to support the second cable 41 with a larger diameter at the same time by the fourth protrusion 84b with a lower height. Of course, as mentioned above, the shape and arrangement of the support base 8 are not limited to this, and the height and width of each convex portion 83a, 83b, 84a, 84b can be based on the actual corresponding cable 4. The size of the wire diameter can be adjusted appropriately. Similarly, the second support portion 83 of the support base 8 can also assist in supporting the cables 4 with different wire diameters. Therefore, when the power cord outer cover 7 is correspondingly closed and disposed on the first opening 61 of the main body 6 to close the container When the portion 60 is placed, the support of the second support portion 83 of the support base 8 is used to clamp and fix a plurality of cables 4 with different wire diameters.

To sum up, the present application provides a power connector and its supporting base, wherein the supporting base is arranged between the second opening of the body and the connector assembly to assist in supporting the different wire diameters passing through the second opening. The multiple cables of the power cable will not slip and roll due to the different diameters of the wires, and can support and fix the setting position stably. When the power cable cover corresponds to the first opening and the accommodating part of the closed body, the The outer cover of the wire and the support base are clamped and tightly fitted together, so that a plurality of cables with different wire diameters are further clamped and fixed. In this way, multiple cables with different wire diameters are not easy to loosen and roll, so as not to cause damage and fall off. In addition, the support base in this case can be a double-sided support structure, so that the support structure can be used on both sides, so that it can be used in a wider range of applications, and can be used to clamp and fix a variety of wires with different wire diameters. cable, which is more convenient to use.
