Abstract

The utility model relates to a contact probe, which is mainly provided with a plastic shell with transverse holes. A plurality of loop parts with central transverse holes are formed around the edge of each transverse hole on the upper part of the shell; a metal inner sleeve is positioned inside each transverse hole; an inner thimble and a spring that sticks to the bottom of the inner thimble are arranged in each inner sleeve. A plurality of metal end caps for sealing up the transverse holes are further arranged so as to compose the contact probe that can enhance electric conduction effect.

Description

Contact probe

Technical field

The utility model is to belong to a kind of contact probe, refers to a kind of contact probe that can improve conductivity especially.

Background technology

Along with the progress of mechanics of communication, technological layer also improves thereupon, and what be most widely used is the improvement of mobile phone.

The mobile phone of commonly using generally is to establish battery or antenna on mobile phone, and provides contact medium between battery or antenna and substrate with contact probe.See also shown in Figure 4, general contact probe is the housing 60 that comprises a plastic material and have perforation 61, other is provided with the thimble 63 that passes each perforation 61 respectively, each thimble 63 bottom connects a spring 64, and housing 60 differs from the metal cap 65 that a side that thimble 63 protrudes is provided with the relative perforation 61 of sealing institute.

But the above-mentioned contact probe of commonly using has following shortcoming when reality is used:

Because of housing 60 be for plastic material made, so when thimble 63 conduction, easily have the bad situation of conduction to take place; When 64 contractions of the spring in the perforation 61 simultaneously or extension start, 60 of the housings that spring 64 and plastics are made can have sizable frictional force, and hindered the flexible start of spring 64, and then make thimble 63 when contact battery or antenna, desire enters housing 60 domestic demands with the compressing of thimble 63 tops and comparatively requires great effort, and easily causes the wearing and tearing of housing 60 simultaneously.Therefore, the contact probe of commonly using still has inconvenience on using, and still needs further to improve.

The utility model content

The inventor is because commonly use contact probe and use and to still have its shortcoming, and improvement design in addition mainly is to provide a kind of bad contact probe of conduction that improves to be its main goal of the invention.

In order to reach aforesaid utility model purpose, the technological means that the utility model used is to be to provide a kind of contact probe, it is the housing with a plastic material, the housing both sides are formed with the sequence hole of perforation, each perforation periphery of housing top is formed with the ring portion with a center through hole, through hole is corresponding with perforation, is provided with the inner sleeve of a metal material in the perforation; Be placed in the interior thimble in each inner sleeve, thimble has the portion of dwindling and an expansion section in this, dwindles and is formed with probe in the portion, and the expansion section is contained in the through hole and replaces the port edge; A spring that is placed in each inner sleeve and touches with interior thimble bottom connection; And metal material is made and differ from respect to each perforation in thimble protrude out the bonnet of side, this bonnet has a cylindrical sidewall that is formed with several overhead kick shape ring plates, overhead kick shape ring plate is to be positioned at the perforation inwall.

By above-mentioned technological means, contact probe of the present utility model can provide one by the made inner sleeve in order to putting spring of conductive material, make contact probe when conduction, its spring contacted is the logical but not housing that make with plastic material of cover in this, and can effectively improve the conductivity and the operating characteristics of contact probe.

Embodiment

See also Fig. 1 to shown in Figure 3, contact probe of the present utility model is by a housing 10, thimble 20 in several, and members such as several springs 30 and several bonnets 40 are formed.

This housing 10 is made by plastic material, both sides are formed with perforation 11 respectively, housing 10 tops are formed with the ring portion 13 with center through hole 12, the through hole 12 of each ring portion 13 is and the 11 corresponding connections of a perforation, and the diameter of through hole 12 is slightly less than the diameter of perforation 11, is provided with one in addition by the made inner sleeve 14 of metal material in each perforation 11.

Interior thimble 20 is made and be contained in respectively in the inner sleeve 14 with metal, and thimble 20 is formed with one and dwindles a portion 21 and an expansion section 22 in each, is formed with a probe 23 in the portion 21 in dwindling.Dwindling portion 21 is to stretch out housing 10 via through hole 12, and expansion section 22 is to be placed in the through hole 12 and to replace inner edge at through hole 12.

In addition spring 30 is thimble 20 bottoms and being placed in the inner sleeve 14 in being separately positioned on.

Bonnet 40 is made with metal material, and has a cross section that slightly takes the shape of the letter U, bonnet 40 bottoms are rounded and be formed with a cylindrical sidewall, shape is the overhead kick shape ring plate 41 that has number to arrange in the form of a ring on sidewall, each overhead kick shape ring plate 41 is to be convexly set on the cylindrical sidewall, can by this bonnet 40 extruding be entered in the perforation 11 of housing 10, in perforation 11, break away to prevent spring 30 and inner sleeve 14.

During assembling, be earlier inner sleeve 14 to be placed in the perforation 11, then in regular turn the through hole 12 of interior thimble 20 from ring portion 13 stretched out, again bonnet 40 extruding are entered in the perforation 11 behind the inserting spring 30.

By above-mentioned contact probe, its inner sleeve 14 because of metal material can be avoided the spring 30 direct housings 10 that wear and tear that contact with the housing 10 of plastic material, inner sleeve 14 is made by the metal material of tool conductivity simultaneously, can effectively help conduction, simultaneously when spring 30 is compressed or upholds, can effectively reduce the generation of frictional force, to reduce the consume of contact probe.
