Abstract
The utility model describes a kind of novel shell fragment for network-termination device, and comprise base, spring and contact terminal, described contact terminal is connected with base by spring; Contact terminal comprises 1 bottom surface and 2 sides, and these 2 sides are connected with two sides non-conterminous on bottom surface respectively, and are provided with sidewall opening on 2 sides, 2 sides is provided with bottom opening near one end of bottom simultaneously.Owing to have employed above-mentioned technology, the utility model carries out stretching motion by utilizing the elasticity of spring in the direction perpendicular to printed circuit board (PCB), thus eliminates elastic arm longer in conventional elastic piece, and then reduces the usable floor area taking printed circuit board (PCB); Simultaneously all cover the Gold plated Layer with high conductivity at the head of contact terminal, spring and base, thus impedance is reduced while ensureing good weldability, finally reach the designing requirement of ultra-thin, extra small, the high integration meeting network-termination device.
Description
Technical field
The utility model relates to network equipment field, particularly relates to a kind of novel shell fragment for network-termination device.
Background technology
Along with the development of information technology, network-termination device has been widely used in daily life, and such as people's everyday life is requisite especially for the equipment such as mobile phone, panel computer.
At present, the shell fragment in existing network terminal equipment is all the form adopting elastic arm, namely by by outer force compresses, elastic arm leading portion is out of shape thus forms reliable contacts.But, this kind of shell fragment is in order to ensure good elasticity, often need the longer arm of force to do elastic arm, so the size of whole shell fragment just can be caused larger, thus the area taking printed circuit board (PCB) also can along with increasing, and then have impact on the layout of other electronic devices and components, be unfavorable for the designing requirement of ultra-thin, extra small, the high integration of present network-termination device.
Utility model content
In order to solve the problem, the utility model provides a kind of novel shell fragment for network-termination device, possesses structure simple, and the advantage such as take up room little.
Above-mentioned a kind of novel shell fragment for network-termination device, comprise base, spring and contact terminal, described contact terminal is connected with base by spring;
Described contact terminal comprises 1 bottom surface and 2 sides, and described 2 sides are connected with two sides non-conterminous on bottom surface respectively, and described 2 sides are provided with sidewall opening, and the one end near bottom on described 2 sides is provided with bottom opening;
Described spring is less than the external diameter near base one end on spring near the external diameter of contact terminal one end; Described contact terminal is the bullet-shaped structure of hollow.
In said apparatus, described spring is high connductivity spring.
In said apparatus, the surface of the top of described contact terminal, base and spring is all coated with Gold plated Layer.
Advantage of the present utility model and beneficial effect are: the utility model provides a kind of novel shell fragment for network-termination device, stretching motion is carried out in the direction perpendicular to printed circuit board (PCB) by utilizing the elasticity of spring, thus eliminate elastic arm longer in conventional elastic piece, and then reduce the usable floor area taking printed circuit board (PCB); Simultaneously all cover the Gold plated Layer with high conductivity at the head of contact terminal, spring and base, thus impedance is reduced while ensureing good weldability, finally reach the designing requirement of ultra-thin, extra small, the high integration meeting network-termination device.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the explosive view of novel shell fragment in the utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection range of the present utility model with this.
As shown in Figure 1, the utility model describes a kind of novel shell fragment for network-termination device, comprise base 1, spring 2 and contact terminal 3, wherein contact terminal 3 is connected with base 1 by spring 2, this base 1 plays fixation, and contact terminal 3 then can do rectilinear motion by the elastic reaction of spring 2 receiving under External Force Acting; Simultaneously in order to better contact fixing spring 2, so contact terminal 3 have employed the bullet-shaped structure of hollow.
Wherein, above-mentioned contact terminal 3 includes 3 faces, is respectively 1 bottom surface and 2 sides; Shrapnel device can be fixed on outside printed circuit board (PCB) by bottom surface 1, and spacing fixing effect then can be played to spring 2 in 2 sides.
Further, 2 sides of above-mentioned contact terminal 3 are connected with two sides non-conterminous on bottom surface respectively, namely constitute vertical layout, so can play better fixed effect to spring 2.
Simultaneously, 2 sides of contact terminal 3 are all provided with sidewall opening 11, and also bottom opening 12 is all provided with near one end of bottom on these 2 sides, this sidewall opening 11 and bottom opening 12 are all for the ease of installing and fixing spring and stable base and arrange;
In addition, owing to also will meet the stability of shell fragment meeting in prior art better, while thinner requirement, so the size of contact terminal 3 is less than the size of base 1; In order to adaptive this kind of structure, so spring 2 have employed one large one small asymmetric formula structure, be specially on spring 2 and be less than its external diameter near base 1 one end near the external diameter of contact terminal 3 one end;
Preferably, in order to reduce the conducting impedance of device, the spring 2 in the utility model have employed high connductivity spring, and at the top of contact terminal, the surface of base and spring all covers Gold plated Layer.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
