Description
[technical field]
The utility model relates to a kind of contact probe.
[background technology]
Constantly research and develop under the refinement in mechanics of communication, technological layer also improves thereupon, the most extensive person in its applied field is no more than mobile phone (mobile phone) market, also just because of be devoted to the exploitation of mobile phone (mobile phone) technology at present, make that the price of mobile phone (mobile phone) is not high as in the past for another example, and mobile phone (mobile phone) popularity rate improves year by year, has been used widely in recent years, no matter be young man, a middle-aged person or the elderly, staff one machine of can saying so.
The mobile phone of commonly using (mobile phone), generally be to be provided with battery or antenna in mobile phone (mobile phone), provide contact (as shown in Figure 5) between battery or antenna and the substrate with contact salient point, its structure comprises it being to penetrate an outer sleeve (60) with an interior thimble (50), and stretch out outer sleeve (60) outside with the convex extension part (51) of interior thimble (50), the outside sheathed spring of interior thimble (50) (70) that outer sleeve (60) is inner set, be fixed in outer sleeve (60) outside with tail-hood (80) again, but the shortcoming of said structure when reality is used is to be:
Because contact salient point is when assembling, be that tail-hood (80) is sheathed on outer sleeve (60) outside, again with machined into, make outer sleeve (60), tail-hood (80) rotate in the lump, to interfix between tail-hood (80) and outer sleeve (60) with mould, so the shortcoming that has assembling length in man-hour and assembling to be difficult for has necessity of being improved in fact.
[utility model content]
In view of the aforementioned structure of commonly using still has shortcoming on reality is used, the purpose of this utility model provides a kind of contact probe, have can save assembling man-hour, contact is good and non-damageable advantage.
In order to reach aforesaid purpose, the technological means that the utility model used provides a kind of contact probe, comprise the metallic outer sleeve, thimble in the metallic, spring and tail-hood, this outer sleeve is a hollow form cylinder, this outer sleeve one end is established an opening, end is established a hole in addition, form convergent portion adjacent to the place, hole on the outer sleeve, the thimble opposite end is provided with less convex extension part of diameter and socket part in this, be connected and between convex extension part and socket part, be the big portion of diameter, should be arranged in this outer sleeve by interior thimble, the convex extension part is overhanging by this place, hole, and this spring is on the socket part of thimble in being socketed on; It is characterized in that:
On the surface of this outer sleeve, establish an annular groove;
This tail-hood one end forms an opening, and this tail-hood is placed on the outer sleeve outside, and this tail-hood medial extremity is pressed from both sides flat, and fastens in the annular groove of this outer sleeve with the flat place of the folder of tail-hood medial extremity, and this spring is to be positioned at the tail-hood inboard.
Contact probe of the present utility model, can be arranged at and be used as the contact salient point use in the inner draw-in groove of mobile phone (mobile phone), and can for the battery of mobile phone or antenna and substrate on contact conducting, when the contact conducting, can make interior thimble (20) press down and be contacted with really on the tail-hood (40), have to save and assemble man-hour, good, the non-damageable advantage of contact.

[embodiment]
The utility model is a kind of contact probe, sees also shown in Fig. 1 to Fig. 3, comprising:
Metallic outer sleeve (10), interior thimble (20), spring (30) and tail-hood (40) etc.;
This metallic outer sleeve (10), it is a hollow form cylinder, these outer sleeve (10) one ends form an opening (11), end forms a hole (12) in addition, upward locate to be formed with convergent portion (13) adjacent to hole (12) in outer sleeve (10), an end surfaces of going up away from convergent portion (13) in outer sleeve (10) forms one annular groove (14);
Thimble (20) in this metallic, be provided with less convex extension part of diameter (21) and socket part (22) in interior thimble (20) opposite end, be connected and between convex extension part (21) and socket part (22), be formed with the big portion (23) of diameter, interior thimble (20) is to locate to penetrate outer sleeve (10) inside by opening (11), and convex extension part (21) can be located overhanging by hole (12);
This spring (30) is on the socket part (22) that can be socketed on interior thimble (20);
This tail-hood (40), the one end forms an opening (41), tail-hood (40) is to be placed on outer sleeve (10) outside, and it is flat with the riveting die folder with tail-hood (40) medial extremity, so that it fastens certain location in annular groove (14), spring (30) is to be positioned at tail-hood (40) inboard, has to save the assembling advantage in man-hour.
After the combination of mat said structure when using (as Fig. 1,3, shown in 4), the topmost characteristics of the utility model are: when assembling, be to penetrate in the outer sleeve (10) with interior thimble (20), convex extension part (21) on the interior thimble (20) is to locate overhanging by the hole (12) of outer sleeve (10), and spring (30) is on the socket part (22) that is sheathed on interior thimble (20), outer sleeve (10) is again with tail-hood (40) combination, and can be by tail-hood (40) medial extremity with the flat interior location really of annular groove (14) that is riveting in the formation of outer sleeve (10) surface of riveting die folder, can reach and save the assembling effect in man-hour, so the utility model is a kind of innovation and practical design really.
The effect that the utility model can be reached in addition is: be used as the contact salient point use in the inner draw-in groove of mobile phone (mobile phone) but mat metal-coating tube (10), the interior thimble (20) of metallic, metallic spring (30) and metallic tail-hood (40) are arranged at, and can for the battery of mobile phone or antenna and substrate on contact conducting, when the contact conducting, can make interior thimble (20) press down and be contacted with really tail-hood (40) and go up (as shown in Figure 4), have the good advantage of contact, do and have non-damageable advantage.
