Abstract

The utility model discloses a connector terminal, which comprises a welding plate. One end of the welding plate is bent up in arc shape to form a bending part. The tail end of the bending part is bent up and extended relative to the welding plate in an oblique manner to form an elastic arm. The elastic arm is in arc shape raised down. The tail end of the elastic arm is bent and extended to form a contact part. When the connector terminal operates, the elastic arm and the welding plate gradually transit from point contact to surface contact so that the applied force is distributed on the arc-shaped bending part and the elastic arm. With strong compression resistance strength, the connector terminal is suitable for occasion with low operating altitude and large strength.

Description

Bonder terminal

Technical field

The utility model relates to a kind of connector, relates in particular to a kind of bonder terminal.

Background technology

Fig. 1 has disclosed a kind of existing bonder terminal 100 ', and this bonder terminal 100 ' has the welded plate 10 ' of a strip, and welded plate 10 ' the one end arc that makes progress is bent to form kink 20 ', and kink 20 ' is horizontal " U " shape.Kink 20 ' terminal welded plate 10 ' relatively extends to form an elastic arm 30 ' obliquely, elastic arm 30 ' end continues to extend to form a junction 40 ', and connecting portion 40 ' end bends upwards behind the hemicycle again that the direction bending to elastic arm 30 ' extends to form a contact site 50 '.

But, the design of above-mentioned existing bonder terminal 100 ', when active force acts on contact site 50 ' repeatedly, as shown in Figure 2, bonder terminal 100 ' deforms near " U " shape kink 20 ' easily, can not or be difficult to satisfy the workplace that working depth is lower and requirement of strength is bigger.

The utility model content

The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and the bonder terminal of the lower and workplace that intensity is bigger of a kind of suitable working depth is provided.

For achieving the above object, bonder terminal provided by the utility model, comprise a welded plate, the welded plate one end arc that makes progress is bent to form a kink, the terminal welded plate relatively of kink bends obliquely and extends to form an elastic arm, elastic arm is the arcuation to lower convexity, and the terminal bending of elastic arm extends to form a contact site.

As mentioned above, the utility model bonder terminal in the course of the work, elastic arm and welded plate can make distribution of forces on arc kink and elastic arm by contacting gradually to face contact transition, thereby the anti-intensity that compresses is bigger, is fit to the occasion that working depth is low and requirement of strength is bigger.

Embodiment

By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.

See also Fig. 3, the utility model bonder terminal 100 has a bar shaped welded plate 10, welded plate 10 1 ends make progress and are bent to form a kink 20 to arc lower again after arc bends, kink 20 terminal welded plate 10 relatively arc bendings obliquely extend to form an elastic arm 30, elastic arm 30 is the arcuation to welded plate 10 direction projectioies, and elastic arm 30 terminal bendings extend to form a contact site 40.

Described welded plate 10 is offered a perforate 11 near other end center, and welded plate 10 approximate mid-section both sides offer a grooving 12 respectively, and perforate 11 and grooving 12 can reach when welded plate 10 welding and gather tin liquor, prevent to produce on terminal 100 purpose of climbing tin; Contact site 40 is provided with bar shaped convex closure 41, can with connected components is reliably contacted.

See also Fig. 4, the welded plate 10 of the utility model bonder terminal 100 is welded on the circuit board, other assembly that convex closure 41 is docked downwardly against active force the time, elastic arm 30 produces elastic deformations, makes the elastic arm 30 and the contact-making surface of welded plate 10 increase.

In sum, the utility model bonder terminal 100 in the course of the work, elastic arm 30 and welded plate 10 are by contacting gradually to face contact transition, can make distribution of forces on arc kink 20 and elastic arm 30, thereby the anti-intensity that compresses is bigger, is fit to the occasion that working depth is low and requirement of strength is bigger.
