[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0022] Example

[0023] like Figure 1 As shown, Figure 1 Shown is a three-dimensional schematic diagram of a connector in an embodiment.

[0024] The device includes a shell 10 and a terminal 20. The shell 10 is arranged outside the terminal 20. A conductive wire with the external insulating colloid stripped off is inserted into the terminal 20. The terminal 20 is made of conductive material (such as metal). The shell 10 insulates and protects the internal structure.

[0025] like Figure 1, Figure 2 , Figure 3 As shown, Figure 1 FIG. 1 is a three-dimensional schematic diagram of a connector in an embodiment. Figure 2 The three-dimensional schematic diagram of the wiring terminal in the embodiment is shown. Figure 1 , Figure 3 The three-dimensional schematic diagram of the wiring terminal in the embodiment is shown. Figure 2 .

[0026] The housing 10 includes a first protection end 11 and a second protection end 12;

[0027] The connection terminal 20 includes a wire pressing portion 21 and a connecting portion 22. The wire pressing portion 21 includes a first plug hole 211 formed by an arc-shaped plate body, and the connecting portion 22 includes a second plug hole 221.

[0028] The first protection end 11 and the second protection end 12 are respectively arranged outside the wire pressing part 21 and the connecting part 22 , and the second protection end 12 is also provided with an insertion port 13 connected to the opening end of the second insertion hole 221 .

[0029] After the conductive wire is inserted into the plug hole 211 inside the wire pressing part 21, the part is riveted by a jig to make the conductive wire fit with the terminal 20. The plug hole 211 formed by the arc-shaped plate body can increase the contact area between the inserted conductive wire and the terminal. At the same time, the arc-shaped plate body structure facilitates the riveting operation of the jig. After riveting, the conductive wire and the terminal fit more tightly and firmly.

[0030] like Figure 2 , Figure 3 As shown, Figure 2 The three-dimensional schematic diagram of the wiring terminal in the embodiment is shown. Figure 1 , Figure 3 The three-dimensional schematic diagram of the wiring terminal in the embodiment is shown. Figure 2 .

[0031] The first plug hole 211 is a plurality of incompletely enclosed O-shapes. The plurality of incompletely enclosed O-shapes are provided so that the wire pressing portion 21 and the conductive wire are in multi-point contact, and the O-shapes cooperate to further increase the fit between the conductive wire and the terminal 20.

[0032] The inner cavity of the plug interface 13 is horn-shaped, and the diameter of one end close to the second plug hole 221 is smaller than the diameter of the other end. The plug interface 13 is used for plugging with external components, so as to achieve the connection between the device and the outside world. The horn-shaped plug interface 13 makes the connection with the external components stable and has a certain degree of adjustability. For example, when the external component connected to the plug interface 13 rotates, the connection can still be stable and reliable.

[0033] The insertion direction of the inner cavity of the second plug hole 221 is perpendicular to that of the first plug hole 211. The vertical connection mode is set so that the connector is mainly used between mutually perpendicular components to be connected.

[0034] A convex rib 222 is arranged on the outside of the connecting portion 22, and a snap-in groove 23 is also arranged on the bottom plate of the wire pressing portion 21. The convex rib 222 and the snap-in groove 23 play a role in positioning and snapping the shell 10, so that the cooperation between the shell 10 and the connecting terminal 20 is more stable.

[0035] Working principle: The utility model sets a wire pressing part 21, inserts a conductive wire into the plug hole 211 inside the wire pressing part 21, and then rivets the part through a jig to make the conductive wire fit with the terminal 20. The plug hole 211 formed by the arc-shaped plate body can increase the contact area between the inserted conductive wire and the terminal. At the same time, the arc-shaped plate body structure facilitates the riveting operation of the jig. After riveting, the conductive wire and the terminal fit more tightly and firmly. A plurality of incompletely closed O-shapes are set, so that the wire pressing part 21 and the conductive wire are in multi-point contact, and the O-shapes are matched to further increase the fit between the conductive wire and the terminal 20.

[0036] The utility model provides a trumpet-shaped plug-in port 13 so that the connection with the external component is both stable and has a certain degree of adjustability. For example, when the external component connected to the plug-in port 13 rotates, the connection can still be stable and reliable.

[0037] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
