Description

Improved terminal structure

technical field

The utility model relates to electromechanical products, in particular to an improved terminal structure.

Background technique

As shown in Figure 1, there is a shrapnel A2 extending from the upper side of the housing A1 of the common terminal A, through which the shrapnel A2 of the housing A1 can contact and conduct with external electrical components, because one end of the shrapnel A2 is only in contact with the housing A1 is connected, so that terminal A is easy to cause elastic fatigue of terminal A under long-term use, and leads to poor contact of terminal A, which needs to be improved.

Utility model content

The purpose of the utility model is to provide an improved terminal structure, which solves the problems of terminal elastic fatigue and poor contact caused by common terminals after long-term use.

The technical scheme of the utility model is as follows: it includes a terminal body; two piece-shaped parts, which are formed by extending upward from both sides of the terminal body, and are symmetrical to each other; The bottom extends upwards and is located between the two pieces. The tab structure has an extension, a bending part and a touch part. The extension is connected to the bottom of the terminal body, and the bending part is connected to the external electrical The contact of the permanent element; through the design of the extension part, the bending part and the touch part, the terminal structure can be used for a long time, so that the elastic fatigue of the tab structure will not cause poor contact; wherein, the extension part is roughly perpendicular to The bottom surface of the terminal body; the terminal body can be an elongated shell; the terminal body also has a fixing part, which is located at the end of the terminal body, and can be used for a wire to be introduced and connected; the terminal body can be inserted into a terminal seat.

The utility model has the advantages that: the design of the extension part and the bending part can make the terminal body use for a long time, and the lug structure will not cause elastic fatigue to cause poor contact, and has strong practicability.

Detailed ways:

As shown in accompanying drawings 2 and 3, the terminal B of the present invention includes a terminal body C, a two-piece part C8 and a tab structure C1, wherein the terminal body C is the main body constituting the terminal B, which can be a long Shaped shell;

The two pieces C8 are formed by extending upward from both sides of the terminal body C, and are symmetrical to each other;

The tab structure C1 extends upward from the bottom of the terminal body C and is located between the two pieces C8. The tab structure C1 has an extension part C2, a bending part C3 and a contact part C4:

The tab structure C1 is connected to the bottom of the terminal body C through the extension part C2, and can be in contact with external electrical components through the bending part C3;

The extended portion C2 is substantially perpendicular to the bottom surface of the terminal body C. As shown in FIG.

As shown in Figure 4, the fixing part C6 is located at the end of the terminal body C, and a wire E can be inserted and connected; when the terminal B is connecting the wire E, the wire E can be placed in the accommodating groove C7 of the terminal body C Inside, the wire E can be fixed by pressing down the fixing part C6 of the terminal body C.

As shown in Figure 5 and Figure 6, when the user puts the terminal B into the terminal base D, the user aligns the two-piece part C8 of the terminal body C with the guide groove D3 of the terminal base D, and borrows The terminal body C can be continuously extended and placed in the terminal base D by the rib D1 of the terminal base D, wherein when the terminal body C is placed in the terminal base D, the terminal body C is convenient to enter the groove D2 of the terminal base D, At this time, the bent portion C3 of the protruding sheet structure C1 extends to one side of the groove D2;

One part of the terminal body C of the terminal B is provided with a protruding sheet structure C1. The extension part C2 of the protruding sheet structure C1 is connected to the bottom of the terminal body C, and the contact part C4 of the protruding sheet structure C1 is in contact with the contact surface C5 of the terminal body C. Correspondingly, when the counterpart is engaged with the terminal base D, the tab structure C1 of the terminal body C is pressed down and contacts the contact surface C5 of the terminal body C, so as to achieve the purpose of fixing the tab structure C1;

Through the design of the extension part C2, the bending part C3 and the contact part C4 of the protruding piece structure C1, the terminal body C can be used for a long time without causing the elastic fatigue of the protruding piece structure C1 of the terminal body C to cause contact bad.
