Abstract

The utility model relates to a spring sheet. The other end of a welding part corresponding to an extending part is bent upward to form a reverse part. Welding materials and the area of the welding part are increased by the reverse part. With the capillary action of the reverse part and an electric circuit, the welding materials infiltrate a joint area of the welding part and the electric circuit to improve the connection strength of the spring sheet and the electric circuit. Particularly, the reverse part of the welding part is arranged at the tail end corresponding to the outer area of the extending part, so the stitching action of the spring sheet can not be influenced.

Description

The laminated type shell fragment

Technical field

The utility model relates in the electric device to improve with the contacting shell fragment structure that electric circuit connects mutually in order to constitute casing, aims to provide a laminated type elastic piece structure that can obtain preferable strength of connection with electric circuit.

Background technology

As shown in Figure 1, be for as in the electric devices such as notebook computer, the laminated type elastic piece structure schematic diagram that connects mutually in order to the casing that constitutes related electric equipment (as connector etc.) and electric circuit, wherein, shell fragment 10 is to be bent to form contact site 11 and the weld part 12 that is parallel to each other by metal sheet (copper sheet) one, other has an extension 13 to be connected in the two diagonal angle ends of contact site 11 with weld part 12, make whole shell fragment 10 become the structure kenel that contact site 11 is provided in top, weld part 12 zone, and make contact site 11 have the elastic reaction that normality makes progress.

Whole 10 on shell fragment is to utilize the bottom surface of weld part 12 and electric circuit 20 to fit, and utilizes in addition solid welding of welding material 30 again, with being connected of formation shell fragment 10 and electric circuit 20; Again; the laminated type shell fragment in use; it is the pressing position that on average is laid in casing; to guarantee the stressed unanimity in each position of casing; each the relative shell fragment and the binding of electric circuit must be quite firm; influence the pressing of casing effect because of improper coming off to keep away to exert oneself, can cause the phenomenon of short circuit even because of the shell fragment that comes off.

So that, in shell fragment shown in Figure 1 10 structures, be further to dash respectively to be provided with vertically upward an invayination 14 at 12 liang of avris of weld part, and form one in the reflexed zone can be for the breach 15 of inserting welding material 30, so as to increasing the bonding strength of shell fragment 10 and electric circuit 20; Yet so therefore structural design with making invayination 14 enter the zone of extension 12, can hinder the flexible pressing action of shell fragment 10.

The utility model content

Shell fragment of the present utility model is to be bent to form contact site and the weld part that is parallel to each other by the metal sheet one, other has an extension to be connected two diagonal angle ends in contact site and weld part, become the structure kenel that contact site is provided in top, weld part zone, and make contact site have the elastic reaction that normality makes progress; Wherein, weld part is upwards to be bent with an invayination at the end in addition that corresponds to extension.

Obtain an area by invayination increase welding material and weld part, and utilize the capillarity of invayination and electric circuit, make welding material infiltrate the fit area of weld part and electric circuit, and then promote the elastic piece structure of shell fragment and electric circuit strength of connection.

Especially, the invayination of weld part is provided in a side of the tail end place that corresponds to beyond the extension zone, and stretches towards the outer skew back of shell fragment, moves and be unlikely the pressing that influence shell fragment.

Embodiment

For the clear structure of the present utility model of your auditor is formed, and the overall operation mode, cooperate graphic being described as follows now:

The utility model laminated type shell fragment, the basic structure of its whole altar shell fragment is formed as shown in Figure 2, be to be bent to form contact site 11 and the weld part 12 that is parallel to each other equally by metal sheet (copper sheet) one, other has an extension 13 to be connected in the two diagonal angle ends of contact site 11 with weld part 12, make whole shell fragment 10 become the structure kenel that contact site 11 is provided in top, weld part 12 zone, and make contact site 11 have the elastic reaction that normality makes progress; Wherein, shell fragment 10 is to correspond to holding in addition of extension 13 at weld part 12 upwards to be bent with an invayination 14, and two avris of weld part 12 are provided with the breach 15 that can supply welding material to insert.

When reality is used, be as shown in Figure 3, be the pressing position that each shell fragment 10 on average is laid in casing 40, to guarantee the stressed unanimity in casing 40 each position; Especially, shown in Fig. 4 and 5 figure, the invayination 14 of being located at weld part 12 can increase the area of welding material 30 and weld part 12, and utilize the capillarity of invayination 14 and electric circuit 20, make welding material 30 infiltrate the fit area of weld part 12 and electric circuit 20, and insert a large amount of welding materials 30 at the breach 15 of 12 liang of avris of weld part, so as to promoting the strength of connection of shell fragment 10 and electric circuit 20.

Moreover, shell fragment 10 of the present utility model is that further the contact site 11 in addition end that corresponds to extension 13 is to be bent with another invayination 14 downwards, by the sharp-pointed configuration of the set invayination 14 elimination shell fragments 10 of contact site 11 tail ends, to keep away rabbit scratch operating personnel or other peripheral article; In the specific implementation, the invayination 14 of weld part 12, and the invayination 14 of contact site 11 all is to be provided in the tail end places that correspond to beyond extension 13 zone, and stretch towards the outer skew back of shell fragment 20, move and be unlikely the pressing that influence shell fragment 10.

As mentioned above, the utility model provides the laminated type shell fragment another preferable feasible structure, so, offer the application of novel patent in accordance with the law; Yet, above implementation and graphic shown in, be one of the utility model preferred embodiment, be not to limit to the utility model with this, be with, approximate with structure of the present utility model, device, feature etc. such as, identical, all should belong to creation purpose of the present utility model and claim in.
