[0002] The connecting wire is an important carrier for data and power exchange. The connecting wire includes a plug assembly, a terminal and a wire. The terminal is plugged into the plug assembly, and one end of the wire is inserted into the plug assembly and electrically connected to the terminal. In the existing connecting wire, the terminal and the wire are arranged in a straight line. When the wire needs to be bent 90 degrees to be electrically connected to other devices, it needs to be manually bent. The wire can only be used after being bent to 90 degrees. After the wire is bent, the load current will become smaller, affecting the use effect.

DETAILED DESCRIPTION

[0021] The utility model is further described in conjunction with the following embodiments.

[0022] A specific implementation of a table of the utility model is as follows Figure 1 and Figure 2 As shown, it includes a housing 1, in which an upper row of terminals 31, a lower row of terminals 32 and a terminal bracket 4 are arranged. The upper row of terminals 31 and the lower row of terminals 32 are fixedly mounted on the terminal bracket 4. Specifically, the upper row of terminals 31 and the lower row of terminals 32 can be fixedly mounted on the terminal bracket 4 by plugging.

[0023] In this embodiment, the left inner side and the right inner side of the housing 1 are both provided with a second blind hole 12, and the terminal bracket 4 is fixedly installed in the housing 1. Specifically, the left and right sides of the terminal bracket 4 both extend outwardly with a second wedge block 41, and the end of the second wedge block 41 facing the second blind hole 12 is formed with a second inclined surface 42 inclined obliquely inward, and the inclined surface makes it easier for the wedge block to open the rear end of the housing 1. During the assembly process, the terminal bracket 4 is inserted toward the rear end of the housing 1, and after the second wedge block 41 is opened and passes over the rear end of the housing 1, the second wedge block 41 is inserted into the second blind hole 12.

[0024] As an improvement, the rear end of the housing 1 is plugged with a mounting seat 2, and the left and right sides of the mounting seat 2 both extend outwardly with a first wedge block 21, and the left and right inner sides of the housing 1 both have a first blind hole 11 spaced apart from the second blind hole 12, and the end of the first wedge block 21 facing the first blind hole 11 is formed with a first inclined surface 211 inclined obliquely inward, and the inclined surface makes it easier for the wedge block to open the rear end of the housing 1. During the assembly process, the mounting seat 2 is inserted toward the rear end of the housing 1, and after the first wedge block 21 is opened and passes over the rear end of the housing 1, the first wedge block 21 is inserted into the first blind hole 11.

[0025] In this embodiment, the mounting base 2 is provided with a wire perpendicular to the terminal bracket 4, and the wire is fixed in the mounting base 2 by injection molding so that the wire and the terminal bracket 4 are perpendicular to each other, so that the wire of the connecting line is arranged vertically to the plug assembly, which is suitable for use in a 90-degree transfer installation environment.

[0026] In order to improve the smoothness of the installation of the mounting seat 2, the top surface of the mounting seat 2 extends upward with a first clamping protrusion 22, and the inner top surface of the housing 1 is provided with a first slide groove 13. In the assembled state, the first clamping protrusion 22 is inserted into the first slide groove 13. In addition, the left and right sides of the mounting seat 2 both extend outward with a second clamping protrusion 23 located above the first wedge block 21, and the left and right inner sides of the housing 1 both have a second slide groove 14 located above the first blind hole 11. In the assembled state, the second clamping protrusion 23 is inserted into the second slide groove 14.

[0027] A 90-degree connecting line of the present embodiment is provided with a first wedge block 21 on the outer side of the mounting seat 2 and a first blind hole 11 is opened on the inner side of the rear end of the shell 1.
