Another purpose of the present utility model is, proposes a kind of probe unit, and this probe unit has the structure of easy assembling probe, so that the correct assembling probe of operator.

A purpose more of the present utility model is, proposes a kind of probe unit, and it can change the probe of damage individually.

The technological means that the utility model is reached above-mentioned purpose is, a kind of probe unit in the number probes probe slot that is fixed on the probe base under the base interior one by one, makes several probes be arranged in parallel with little spacing that can not change.

Wherein, several probe slots of this probe base predetermined little spacing of being separated by parallel to each other, each probe slot connects the front end and the rear end of this probe base; The end of probe of number probe is extended the front end of this probe base, and its link extends the rear end of this probe base.

Wherein, this probe base is established a clamping slot that traverses portion about it, and each probe has a fastening part and is embedded in this clamping slot.

Wherein, the clamping slot of this probe base is arranged on the position near this probe base front end.

Wherein, comprise that more one combines and locate the location lid of described probe in described probe slot with this probe base.

Wherein, each side space of portion about this probe base is in order to receive the joint portion that this location lid left and right sides protrudes downwards.

Wherein, the bottom land of the assembling grove that is locked to this pedestal was respectively worn by portion about this location was covered by a vertical retaining element.

Wherein, this probe base is fixed in this assembling grove, and the end of probe of this probe is extended the front end of this pedestal; This pedestal is established a circuit board, has several contacts on it, is connected with the link of this probe.

Wherein, this location lid is made for insulation materials such as plastic cement or potteries.

The utility model beneficial effect: it is fixing that the utility model probe unit obtains each probe, remains on both allocations when detecting, and avoids deflection, shrinks back, moves or pin is pressed unequal problem.Moreover also have the structure of easy assembling probe, can change the probe of damage individually.

For ease of explanation the utility model represented central idea in above-mentioned novel content one hurdle, express with specific embodiment now.Various different objects and deflection thereof or displacement system but not is drawn in the ratio of actual components in the ratio that is suitable for exemplifying explanation among the embodiment, close chat earlier bright.

Embodiment

As Fig. 2, the utility model probe unit is mainly counted probe 31 in a pedestal 20 inside with little spacing arrangement.Protruding out this pedestal 20 front end persons is the end of probe 311 of this probe 31, in order to contact a measured panel.

As Fig. 3, Fig. 4, Fig. 5, show the structure of this this probe 31 of pedestal 20 internal fixation with three-dimensional exploded view.Comprise a probe base 40, number probe 31, and a location covers 60.

This probe base 40 is established several probe slots 41, the number probe slot 41 predetermined little spacings of being separated by parallel to each other, and each probe slot 41 connects the front end 42 and the rear end 43 of this probe base 40.This pedestal 20 is horizontally set with a clamping slot 44 near the position of its front end 42.Each probe 31 has a link 312 and an end of probe 311, and its probe bodies near this end of probe 311 is established a fastening part 313.Each probe 31 is embedded in this probe slot 41, and its end of probe 311 is extended the front end 42 of this probe base 40, and its link 312 extends the rear end 43 of this probe base 40, and the fastening part 313 of this probe 31 is embedded in this clamping slot 44.This location lid 60 combine with this probe base 40 and described probe 31 compactings is not had the anxiety of disengaging, and the joint portion 61 of the downward protrusion of 60 left and right sides is covered in order to receive this location in each side space 45 of about this probe base 40.This location lid 60 is made for insulation materials such as plastic cement or potteries.

As Fig. 3, Fig. 6, above-mentioned probe base 40 is located in the default assembling grove 21 of this pedestal 20, and the location cover about 60 one and respectively worn the bottom land that is locked to this assembling grove 21 by a vertical retaining element 62, and then this probe base 40 is fixed in this assembling grove 21.

As Fig. 3, Fig. 7, this probe 31 is embedded at this probe slot 41, and its end of probe 311 is extended the front end of this probe base 40, and its link 312 extends the rear end of this probe base 40.This pedestal 20 is provided with a circuit board 22, and this circuit board 22 is provided with several contacts 221 and is connected with the link 312 of this probe 31.

Above-mentioned each probe 31 gets by this probe slot 41 and permanently is arranged in parallel with changeless little spacing, each probe 31 is embedded in the clamping slot 44 of this probe base 40 with its fastening part 313 again, and each probe 31 is moved before and after not understanding, cooperate this location to cover 60 and each probe 31 can not moved up and down.Therefore, each probe 31 obtains omnibearing fixing, remains on both allocations when detecting, and can avoid deflection, shrink back, moves or the uneven problem of pin pressure.Moreover, these probe slot 41 convenient assembling and position probe 31 one by one, whether contact 221 convenient affirmation probe 31 assemblings on this circuit board 22 are correct, that is, when probe 31 embeds the clamping slot 44 of this probe base 40 with fastening part 313, the link 312 of this probe 31 promptly should with the 221 relative contacts of a contact, if when the not corresponding situation of probe 31 and contact 221 takes place, it is incorrect promptly to represent probe 31 to assemble.The utility model said structure also helps changing any impaired probe.
