Description

Shrapnel to limit indentation depth

technical field

The utility model relates to a shrapnel, in particular to a shrapnel used in an electronic device to support and slow down the vibration of a circuit substrate and capable of limiting the depression depth. It is protected by the upper and lower height stop plates against each other so that the shrapnel will not be excessively depressed and damaged; the upper and lower gaps of the shrapnel are covered by the height stop plate to prevent foreign objects or external forces from being caught and damaged by the shrapnel Shrapnel, and it can avoid the loose shrapnel hooking each other and tangling together when feeding.

Background technique

Vehicle electronic devices or portable electronic devices often face the test of vibration. In order to slow down the vibration of the electronic components, shrapnel is generally used to assist in solving the problem.

Taking a Personal Digital Assistant (PDA) as an example, a plurality of electronic components are disposed on a circuit substrate. In the past, copper pillars were used to support and fix the circuit substrate on the fixed substrate below the circuit substrate. In order to slow down the vibration, the later development trend is to replace part of the copper pillars with several shrapnel.

There are many M-type shrapnel patents in the prior art, which are characterized in that the shrapnel is a transverse M-shape in side view and has three elastic bent plates. For example, China Taiwan Patent No. M309838, M257526, and No. 00568512 patents, the arcs of the three elastic curved plates are about the same. When the shrapnel vibrates, although the three elastic curved plates absorb the energy of the vibration evenly, they are also equivalent to each other. Containment, resulting in uncoordinated shaking when shaking.

For example, China Taiwan Patent No. M253973 and Patent No. 00508135, the middle elastic curved plate of these patented technologies is relatively large. There are three elastic bending plates to bear the pressure. When the pressure is too large or the depression is excessive, the bending angle of the shrapnel will be damaged due to material fatigue, causing the shrapnel to lose its original elasticity.

For example, China Taiwan Patent No. 00592432, it has a structural design for the second section to withstand depression, so as to further improve the above-mentioned problems. When the elastic sheet in this technology is depressed, its extended end will touch the elastic curved plate, thereby limiting excessive depression. However, the ends extending up and down are only used to elastically touch the elastic bending plate to resist excessive depression. When a stronger pressure is applied, the ends will still explode laterally and damage the shrapnel, so its protection is still intact. is limited.

In addition, when designing the conventional shrapnel, less attention is paid to the covering of the end of the elastic body. Therefore, when assembling on the production line, it is easy to be caught by a foreign object or force to the end of the elastic body and damage the shrapnel. Or when feeding materials in processes such as electroplating, the loose shrapnel are hooked to each other and tangled together.
