The probe of commonly using (as shown in Figure 4), its structure includes the outer sleeve (60) that an inside is hollow, outer sleeve (60) outer rim top and bottom have smaller part (61) and big portion (62) respectively, outer sleeve (60) inside is provided with spring (70), establish an interior thimble (80) with probe (81) on the spring (70), make thimble (80) bottom be arranged at outer sleeve (60) inside with pressing in outer sleeve (60) top, to form a probe, this probe is when desiring with a housing (90) assembling, be fixed as one after must making probe penetrate formed holes, housing (90) both sides (91) respectively, outer sleeve (60) bottom is welded on the circuit board, but above-mentioned traditional type is commonly used the shortcoming of contact probe when reality is used and is:

Assembling long, assembling inconvenience in man-hour: because of probe must each self assembly after, just can be assembled on the housing (90) respectively, on a housing (90), then need to assemble respectively two probes, have assembling inconvenience, assembling long shortcoming in man-hour, necessity of being improved is arranged in fact.

[utility model content]

The purpose of this utility model is to be to provide a kind of contact probe, and it is simple in structure, and have easy to assembly, can save the assembling man-hour advantage.

To achieve the above object, the utility model provides a kind of contact probe, it is characterized in that: comprising: plastic housing, metal interior thimble, spring and metal bonnet,

These housing both sides are respectively equipped with the perforation of a upper and lower perforation, are provided with the ring portion that central authorities have through hole in this housing top, and this through hole is upper and lower corresponding with this perforation,

Should be provided with smaller part and big portion respectively in interior thimble upper and lower part, this smaller part is provided with probe, and this smaller part and this probe are to be protruded out by this through hole,

This spring is located at thimble bottom in this, and this spring is positioned at this perforation,

Extend up in this bonnet place and to be provided with a ring plate, protrude out in the place, top of this ring plate and be provided with the overhead kick that several are arranged in the form of a ring, this ring plate is to be assembled in the perforation of this lower housing portion by this overhead kick to locate.

Described contact probe is characterized in that: the diameter of this through hole is less than the diameter of this perforation.

Described contact probe is characterized in that: the bottom of this bonnet has rounded portions.

Described contact probe is characterized in that: the section of this bonnet takes the shape of the letter U.

Described contact probe is characterized in that: the diameter of this each overhead kick is greater than the perforation diameter of this housing.

Contact probe provided by the utility model, the plastics system housing that is made of one piece and has two perforations, assemble top in each perforation place respectively and have thimble, metallic spring and metallic bonnet in the metallic of probe, this bonnet section takes the shape of the letter U, and has ring plate, form several overhead kicks on the ring plate of this bonnet respectively, can insert each relative perforation, make the certain respectively internal face place that is positioned perforation of overhead kick of each ring plate by ring plate with several overhead kicks;

The utlity model has simple in structure, easy to assembly, can save the assembling man-hour advantage.

Fig. 4 be commonly use structure in conjunction with cutaway view.

[embodiment]

Contact probe of the present utility model sees also shown in Fig. 1 to Fig. 3, mainly is to be formed with housing (10), interior thimble (20), spring (30) and bonnet (40) etc.;

This plastic housing (10), be formed with the perforation (11) of a upper and lower perforation respectively in this housing (10) both sides, be formed with the ring portion (13) that central authorities have through hole (12) in housing (10) top, through hole (12) is upper and lower corresponding with perforation (11), and the diameter of through hole (12) is slightly less than the diameter of perforation (11);

Thimble (20) in this metallic is formed with smaller part (21) and big portion (22) respectively, and is formed with probe (23) on the smaller part (21) in interior thimble (20) upper and lower part, smaller part (21) and probe (23) can be located to protrude out by through hole (12);

This spring (30) is to be located at interior thimble (20) bottom and to be positioned at perforation (11);

Analyse and observe the metallic bonnet (40) that takes the shape of the letter U, its bottom tool rounded portions, on bonnet (40), extend to form a ring plate (41) up, place, top in ring plate (41) protrudes out several overhead kicks of arranging in the form of a ring (42) of formation, the slightly larger in diameter of each overhead kick (42) enters each relative perforation (11) inside by each overhead kick (42) extruding and locatees really in the diameter of perforation (11).

When assembling, it is the interior thimble (20) of locating to assemble respectively from the bottom to top top tool probe (23) in the perforation (11) of housing (10) both sides, smaller part (21) partly and probe (23) can be located to protrude out up by through hole (12), big portion (22) is positioned at perforation (11) to locate, spring (30) is to be located in the perforation (11), again bonnet (40) is entered in the corresponding perforation (11) by each ring plate (41) extruding, and by metallic and have the ring plate (41) of overhead kick (42), effect by overhead kick (42), can locate really in perforation (11) the wall place that plastics system housing (10) forms, reach easy to assembly, can save the assembling advantage in man-hour, the bonnet in the utility model (40) can be fixed as one with circuit board welding at last.

Therefore, in the utility model in when assembling, only need one-body molded plastic housing (10), thimble (20), spring (30), bonnet (40) part of etc.ing and give fixingly in the inner assembling in regular turn respectively of housing (10) can reach purpose easy to assembly, that man-hour is assembled in saving.
