Description

Technical Field

[0001] The utility model relates to the technical field of cable connection, in particular to a wiring plug. Background Art

[0029] The purpose of the utility model is to provide a wiring plug to solve the problems existing in the above-mentioned prior art, so as to save installation space and improve the reliability of cable connection.

[0030] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] The utility model provides a wiring plug 100, comprising a copper bar 1, a shell and a fixing part 3, wherein the first end of the copper bar 1 can be conductively connected to an external device, the second end of the copper bar 1 is connected to a cable copper wire 6, the copper bar 1 is a right-angle structure, the first end and the second end of the copper bar 1 are respectively located on two right-angle sides of the copper bar 1; an insulating structural layer is arranged on the outer surface of the cable copper wire 6; the shell wraps the connection between the copper bar 1 and the cable copper wire 6, and the shell is made of insulating material; the fixing part 3 is sleeved on the outside of the first end of the copper bar 1 and connected to the shell, and when the first end of the copper bar 1 is conductively connected to the external device, the fixing part 3 can be connected to the external device.

[0032] The wiring plug 100 of the present invention adopts a copper busbar 1 with a right-angle structure, a right-angle side of the copper busbar 1 is conductively connected to an external device (i.e., a counterpart), and the other right-angle side of the copper busbar 1 is connected to a cable copper wire 6, thereby realizing the connection between the cable copper wire 6 and the external device, and effectively reducing the installation space of the cable when it is installed at an angle; at the same time, the shell is used to protect the connection between the copper busbar 1 and the cable copper wire 6, thereby ensuring the connection reliability between the copper busbar 1 and the cable copper wire 6; in addition, a fixing member 3 is also provided, and when the copper busbar 1 is conductively connected to an external device, the fixing member 3 is connected to the external device, thereby further improving the connection firmness between the wiring plug 100 and the external device, and ensuring the working reliability of the wiring plug 100.

[0033] It should be explained here that it is common knowledge for those skilled in the art that the device uses the wiring plug 100 to connect to the external device to be connected. The external device to be connected or required to be connected is also called a counterpart. Therefore, the descriptions of the external device and the counterpart are not contradictory and will not be repeated here.

[0034] In this specific embodiment, the copper busbar 1 is a variable diameter structure, the cross-sectional area of ​​the first end of the copper busbar 1 is smaller than the cross-sectional area of ​​the second end of the copper busbar 1, and the cross-sectional area of ​​the end of the copper busbar 1 connected to the cable copper wire 6 is larger, so that the copper busbar 1 can be reliably connected to the cable copper wire 6 to ensure the conduction reliability, and the cross-sectional area of ​​the end of the copper busbar 1 that is conductively connected to the external device is smaller, which meets the wiring requirements and is beneficial to saving wiring space.

[0035] The housing includes an inner shell 4 and an outer shell 5. The inner shell 4 is sleeved on the outside of the connection between the copper busbar 1 and the cable copper wire 6. The outer shell 5 is sleeved on the outside of the inner shell 4. Both the inner shell 4 and the outer shell 5 can be made of plastic. Both the inner shell 4 and the outer shell 5 can protect the copper busbar 1 and the cable copper wire 6, and ensure the connection stability and reliability between the copper busbar 1 and the cable copper wire 6.

[0036] In order to save installation space, the inner shell 4 and the outer shell 5 are both bent structures, and transition slopes are provided at the outer corners of the inner shell 4 and the outer shell 5 to further reduce the occupied space of the wiring plug 100 .

[0037] Specifically, the end of the cable copper wire 6 away from the copper bus 1 is covered with a first insulating layer 7, the first insulating layer 7 is covered with a shielding layer 8, and the shielding layer 8 is covered with a second insulating layer 9; a copper foil 10 is arranged between the inner shell 4 and the outer shell 5, one end of the copper foil 10 is connected to the shielding layer 8, and the other end of the copper foil 10 is connected to the fixing member 3, and the fixing member 3 can be made of metal. In the wiring plug 100 of the utility model, the fixing member 3 made of metal is connected to the copper foil 10, and the copper foil 10 is connected to the shielding layer 8 to achieve the shielding effect of the wiring plug 100. In practical applications, it can be connected to the shell of the counterpart.

[0038] More specifically, one end of the fixing member 3 is located between the inner shell 4 and the copper foil 10, and the other end of the fixing member 3 is protruded from the outer shell 5. The portion of the fixing member 3 protruding from the outer shell 5 has a fixing installation hole 11. The fixing installation hole 11 can be used to fix the fixing member 3 to an external device, thereby further ensuring the working stability and reliability of the wiring plug 100.

[0039] The wiring plug 100 of the present invention further includes a sealing member 2, which is sleeved on the outside of the first end of the copper busbar 1. The sealing member 2 is connected to the fixing member 3. When the copper busbar 1 is conductively connected to an external device and the fixing member 3 is fixedly connected to the external device, the sealing member 2 can play a sealing role. Combined with the protection of the plastic shell 5, the protective effect of the wiring plug 100 is enhanced.

[0040] In other specific embodiments that can be realized by the present invention, the outer peripheral surface of the seal 2 has multiple groups of annular protrusions 13, and the annular protrusions 13 are arranged at equal intervals along the axial direction of the seal 2. When the copper bus 1 is inserted into the socket of the external device or connected to the external device in other ways, the seal 2 can block the gap between the wiring plug 100 and the external device. The shell of the external device squeezes the seal 2, and the annular protrusions 13 are deformed to achieve the blocking of the gap at the connection, thereby improving the adaptability of the wiring plug 100 to different external devices, further improving the sealing reliability of the seal 2, and thus facilitating the improvement of the connection safety factor between the wiring plug 100 and the external device.

[0041] Furthermore, the first end of the copper busbar 1 has a conducting connection hole 12, so that the copper busbar 1 can be connected to an external device. The conducting connection hole 12 is provided on the copper busbar 1, which is convenient for connecting and installing the hand piece with the wiring plug 100 using a fixing bolt, thereby improving the flexibility and adaptability of the wiring plug 100. In practical applications, the distance between the conducting connection hole 12 and the fixing piece 3 is reasonably set to ensure that the wiring plug 100 can meet the functions of conduction, watertightness, shielding, etc. when it is installed in place, reduce the difficulty of installing the wiring plug 100, and improve the convenience and reliability of wiring.

[0042] It should also be noted that the copper busbar 1 is crimped to the cable copper wire 6, which is reliable, avoids loosening, cracking, etc., and has high production efficiency. In other specific embodiments of the utility model, the copper busbar 1 and the cable copper wire 6 can also be connected in other ways to meet different working conditions.

[0043] Compared with the cable angle installation method in the prior art, the wiring plug 100 of the present invention adopts a copper bus 1 with a right-angle structure to minimize the installation space. For details, see Figure 4 The utility model utilizes the inner shell 4 and the outer shell 5 to provide effective protection for the connection between the copper busbar 1 and the cable copper wire 6, thereby ensuring the connection reliability between the copper busbar 1 and the cable copper wire 6. The metal fixing part 3 is provided with a fixing installation hole 11 to ensure that the wiring plug 100 is firmly installed, thereby further improving the working stability and reliability of the wiring plug 100.

[0044] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
