SUMMERY OF THE UTILITY MODEL

Aiming at overcoming the defects, the utility model provides a terminal.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a terminal, contains terminal main part and cover, terminal main part contains integrated into one piece's cable crimping portion and connecting portion, cable crimping portion is the opening form, and its inner wall sets up at least two sets of crimping convex closure, the connecting portion outer wall is fixed with the cover, the connecting portion inner wall sets up arc contact shell fragment, set up at least two sets of cockscomb structure contacts on the arc contact shell fragment.

According to the utility model discloses a further embodiment, further include, the connecting portion outer wall still is provided with integrated into one piece's moving back prevention shell fragment, the cover sets up corresponding opening, moving back prevention shell fragment stretches out from the opening part, plays the effect that prevents the terminal and give way or become flexible, stability when further improving the connection.

According to the utility model discloses a further embodiment, further include, the moving back prevention shell fragment has two sets ofly, sets up respectively at the last outer wall of connecting portion and outer wall down, and the moving back prevention shell fragment of two sets of symmetric distributions can further improve the stability ability when connecting.

According to the utility model discloses a further embodiment, further include, arc contact shell fragment has two sets ofly, sets up respectively at the last inner wall of connecting portion and lower inner wall, and the arc contact shell fragment of two sets of relative settings forms inseparable narrow passage, guarantees the stability of connecting between the terminal.

According to another embodiment of the present invention, further comprising, the material of the sleeve is stainless steel.

According to another embodiment of the present invention, the terminal body is made of copper alloy.

The beneficial effects of the utility model are that, the cover provides support and fixed action for the terminal main part, stability when guaranteeing the terminal connection, through setting up the crimping convex closure at cable crimping portion inner wall, guarantee the terminal when with the cable crimping, the power of pulling off of increase cable, through setting up arc contact shell fragment at the connecting portion inner wall, and press the more than two zigzag contact on arc contact shell fragment, the advantage that has is, become a plurality of contact contacts contact by a point contact before, overcurrent capacity can strengthen, increase the shock resistance simultaneously, prevent the instantaneous failure.

Drawings

The present invention will be further explained with reference to the drawings and examples.

FIG. 1 is a schematic view of a prior art terminal structure;

FIG. 2 is a perspective view of the present invention;

FIG. 3 is a first cross-sectional view of FIG. 2;

fig. 4 is a second sectional view of fig. 2.

In the figure, the terminal comprises a terminal main body 1-1, a cable crimping part 1-2, a connecting part 2, a sleeve 2-1, an opening 3, a crimping convex hull 4, an arc contact elastic sheet 5, a sawtooth contact 6 and an anti-return elastic sheet.

Detailed Description

Fig. 2 to 4 are schematic structural diagrams of the present invention, a terminal, which comprises a terminal main body 1 and a sleeve 2, wherein the terminal main body 1 comprises an integrally formed cable crimping part 1-1 and a connecting part 1-2, the cable crimping part 1-1 is in an open shape, the inner wall of the cable crimping part is provided with at least two sets of crimping convex hulls 3, the outer wall of the connecting part 1-2 is fixed with the sleeve 2, the inner wall of the connecting part 1-2 is provided with an arc contact elastic sheet 4, and the arc contact elastic sheet 4 is provided with at least two sets of zigzag contacts 5.

In this application, cover 2 cup joints at connecting portion 1-2 outer wall, for terminal main part 1 provides support and fixed action, stability when guaranteeing the terminal connection, through set up crimping convex closure 3 at cable crimping portion 1-1 inner wall, guarantee the terminal when with the cable crimping, increase the pull-off force of cable, through set up arc contact shell fragment 4 at connecting portion 1-2 inner wall, and stamp more than two zigzag contact 5 on arc contact shell fragment 4, the advantage that has is, when the terminal in this application is inserted to slice male terminal, become a plurality of contact contacts contact by a point contact before, overcurrent ability can strengthen, increase the shock resistance simultaneously, prevent the instantaneous failure.
