Abstract

The utility model provides a cross type elastic plate, which comprises fixed surfaces, elastic sections, supporting surfaces, cross sections, abutting surfaces, supporting sections, bending parts, etc. Each surface and each section are connected by one bending part. The surfaces and the sections are integrated into one, which forms the cross type elastic plate with the fixed surfaces and the supporting surfaces. The cross overlapping position of the cross type elastic plate does not need to be riveted. The elastic sections and the cross sections of the cross type elastic plate connect the entire elastic plate in a streamline mold. Thus, a hooking and clamping problem caused by a concave space is relieved.

Description

The chiasma type shell fragment

Technical field

The utility model system provides a kind of staggered form shell fragment, refers to a kind of accessory part as printed circuit board (PCB) especially, and the staggered form shell fragment of ground connection and electromagnetic protection effect and tool flexible adjustment effect is provided.

Background technology

Electronic industry is used always and provided the shell fragment of flexible adjustment as the assembling accessory part generally is to be bent into metal material, be set on the printed circuit board (PCB) by the surface mount mode then, has elasticity after the shell fragment bending of making by metal material, when being connected, provide path and the buffering and the flexible adjustment effect of ground connection or electromagnetic protection at assembling or other assembly with circuit board.

Shown in Fig. 1, a kind of existing S configuration shell fragment, its shell fragment bending place common property is given birth to two dented space 11,12, dented space causes this type of shell fragment many and when depositing in the space simultaneously in quantity easily, often cause to each other and collude card and be entangled with the situation that is difficult to resolve, in the disassembly process of the packing of product, also very easily collude and tangle the flexible packaging material, packaging material are damaged to cause shell fragment to pull distortion even cause, and how to make its automatic separation in the common mechanical automated production process with vibration mode, under the location and the situation of conveying assembly, this kind assembly colludes card and is entangled with situation and also can't gets rid of completely.

Be illustrated in figure 2 as the seal type shell fragment that is disclosed in the TaiWan, China M250512 patent case, though utilized structural design, reduce elastic sheet body is colluded card in the mechanical automation production process problem, but the curved molded overlapped part of shell fragment is positioned at the stationary plane of bottom, need to handle the integrality that just can reach shell fragment integral body through the lap over riveted, thisly the seal type elastic sheet body is carried out the stationary plane riveted handle production to shell fragment, not only many one procedure have also increased production cost.

In view of this, the utility model promptly is to provide a kind of elastic sheet body of can improving to design the upward caused improper required riveted processing problems on card and the minimizing shell fragment processing procedure of colluding.

Summary of the invention

The purpose of the utility model is to provide a kind of chiasma type shell fragment, the chiasma type shell fragment is that a metal material is cut out molded sheet metal, sheet metal is made the chiasma type shell fragment through the curved configuration of pressing, and its two end is done overlapping at transposition section, handles admittedly can make stationary plane need not to do overlapping riveted.

Another purpose of the utility model is to provide a kind of improper situation of colluding card of avoiding producing between shell fragment and shell fragment in the process of carrying or depositing, prevent that shell fragment from pulling distortion because of colluding OK a karaoke club, and reduce the chiasma type shell fragment of being entangled with the possibility of colluding card and being convenient to mechanical automation vibrations separation processing.

The chiasma type shell fragment, it comprises stationary plane, kink, stretch section, breasting face, abutment face, the section of leaning and transposition section etc. that one links to each other, its stationary plane system is in order to be fixedly attached to circuit board, stretch section system extends upward via kink from one of stationary plane end, the breasting face of the providing one main elasticity arm of force, and transposition section to be the other end by stationary plane extend upward via kink, transposition section is the curved two molded ends of the warp of chiasma type shell fragment, and is intersected with each other overlapping; The also stressed situation of the transposition section application of force to pressing that present of two transposition sections produces elasticity arm of force function during to pressure when breasting face is stressed, brings into play the elasticity arm of force simultaneously with stretch section and supports the suffered pressure of breasting face.

Therefore the utility model system provides a kind of chiasma type shell fragment that improves shell fragment manufacturing and appearance structure, stretch section and transposition section join via kink and breasting face and stationary plane, it forms between breasting face and stationary plane and intersects the two elasticity arm of forces of horizontal mistake, because stretch section and transposition section are all via the curved breasting face and the stationary plane of being connected to of kink streamline, make the outer surface of the chiasma type shell fragment level and smooth streamline that becomes, for shell fragment depositing to each other, be difficult for causing the situation of colluding card mutually to take place.Moreover, also reduce and collude extension because of producing as touching of flexible packaging materials such as polybag, cause packaging material breakage or shell fragment to be colluded extension and pull and the situation generation of gross distortion.

Embodiment

As shown in Figure 3, be the preferred embodiment of one of the utility model, chiasma type shell fragment 30 comprises the stationary plane 301 that one links to each other, kink 302, stretch section 303, kink 304, breasting face 305, kink 306, transposition section 307,308, kink 309 and fixing hole 310, the stationary plane 301 of chiasma type shell fragment 30 can be fixed for surface mount, stationary plane 301 has a location hole 310 that chiasma type shell fragment scolding tin when carrying out surface mount can be adsorbed on the inwall in hole and accomplishes positioning and fixing preferably, stationary plane 301 is connected to stretch section 303 via a kink 302, stretch section 303 is connected to breasting face 305 via a kink 304 again, and the breasting face other end links transposition section 307 through kink 306 and is superimposed with the transposition section 308 that is linked to stationary plane 301 via kink 309.
