Offer reset force is changed, but not limited to this.
Please refer to Fig. 2, Fig. 4 and Fig. 5, built-in chamber 112 along needle shaft 2 axially backward successively comprising be connected first built in
Chamber 112b built in chamber 112a and second, the radial dimension of chamber 112a built in first greater than chamber 112b built in second radial dimension with
So that the joint of the two is formed shoulder 113, kept out when needle shaft 2 is located at compression position with 113 phase of shoulder, to prevent needle shaft 2 excessive
Return unit 3 is compressed, simultaneously, it is ensured that return unit 3 has biggish elastic potential energy, thus more reliable, Gu Tai when needle shaft 2 being enable to reset
Shoulder 113 plays the role of limit and protection.Return unit 3 is located at chamber 112b built in second.Specifically, chamber 112a built in first and
Chamber 112b is respectively cylindrical cavity built in two.
Fig. 2, Fig. 4 and Fig. 5 are please referred to, needle shaft 2 is along it axially backward successively comprising for contacting with exterior electrical components 200
Needle section 21 and with the integrally formed trunk portion 22 of needle section 21, needle section 21 protrudes into guide-localization chamber when initial position
111, it is more excellent that needle section 21 is had at a distance from one section of guide-localization chamber 111 with accent 12, therefore facilitate exterior electrical components 200
It is not contacted with needle section 21 also and just has been carried out guiding and positioning, so that the guide-localization formula probe 100 of the utility model is led
To and positioning it is quick and accurate.Certainly, according to the needs of actual conditions, needle section 21 stretches to or stretches out guiding when initial position
Positioning chamber 111, it is same that there is the function of being oriented to and position to exterior electrical components 200, therefore be not limited.It is preferably needle
The radial dimension on head 21 is greater than the radial dimension of trunk portion 22, and needle section 21 compresses shoulder 113 when being located at compression position, by
The mutual cooperation of needle section 21 and shoulder 113 so that needle shaft 2 will not excess compression return unit 3 so that the reset of needle shaft 2 away from
From relatively safety, needle tubing 1 will not be skidded off.Trunk portion 22 radially outward protrudes out abutting portion 23, abutting portion 23 and along needle shaft 2
Chamber 112b clearance fit built in two.By abutting portion 23, so that the conflict active force between needle shaft 2 and return unit 3 is more uniform,
So that needle shaft 2 and return unit 3 do not generate shaking when contradicting.Specifically, abutting portion 23 is along the axial by trunk portion 22 of needle shaft 2
It is separated out the first cylinder 221 and the second cylinder 222, the first cylinder 221 is between needle section 21 and abutting portion 23, the second cylinder
222 are located at the rear of abutting portion 23.It is abutted again with abutting portion 23 more specifically, return unit 3 is first sheathed on the second cylinder 222, by
Return unit 3 is placed through by the second cylinder 222, the displacement for the generation of return unit 3 provides guiding role, is more conducive to needle shaft 2
The sliding of opposite needle tubing 1, can't generate offset.For example, the top surface of needle section 21 is plane, certainly, according to practical feelings
The top surface of the needs of condition, needle section 21 is spherical surface, and but not limited to this.
In conjunction with Fig. 4 and Fig. 5, the working principle of the guide-localization formula probe 100 of the utility model is illustrated: when this reality
When just being contacted with the needle shaft 2 of novel guide-localization formula probe 100 and exterior electrical components 200, state is as shown in Figure 4；At this time
Exterior electrical components 200 enter guide-localization chamber 111 from accent 12, and slide certain distance along guide-localization chamber 111
(distance be according to actual needs flexible design) is just contacted with the needle section 21 of needle shaft 2；Then, continue externally electronics member
The side direction pushing tow needle shaft 2 of part 200 slides onto compression position, slides onto compressed-bit in 20 pushing tow needle shaft 2 of exterior electrical components
During setting, exterior electrical components 200 make exterior electrical components 200 and guiding fixed because constantly entering guide-localization chamber 111
Gap between the side chamber wall 111a of position chamber 111 is by gradually becoming smaller greatly, thus exterior electrical components 200 and guide-localization chamber 111
Side chamber wall 111a it is more and more closer, to guide exterior electrical components 200 steady and accurately pushing tow needle shaft 2 slides onto compression
Position realizes that the needle section 21 of exterior electrical components 200 and needle shaft 2 is connected.
Compared with prior art, the guide-localization formula probe 100 of the utility model includes guide-localization by accommodating chamber 11
Chamber 111 and built-in chamber 112, accent 12 is located at the front of guide-localization chamber 111, and the radial dimension of guide-localization chamber 111 is along needle
Axis 2 is in diminishing arrangement axially backward, therefore works as the guide-localization formula probe 100 and exterior electrical components of the utility model
In 200 docking operations, exterior electrical components 200 first enter guide-localization chamber 111 from accent 12, then in guide-localization chamber 111
Guiding under slide into be located at built-in chamber 112 in needle shaft 2 abuts until, and in conjunction with guide-localization chamber 111 radial dimension
It is backward in diminishing arrangement, therefore the gap meeting between exterior electrical components 200 and the side chamber wall 111a of guide-localization chamber 111
Smaller and smaller, exterior electrical components 200 and guide-localization chamber 111 are increasingly closer, to limit exterior electrical components 200
Shake range prevents exterior electrical components 200 from shifting and shadow in docking operation to reach the function of guiding and positioning
The loud conducting with probe 100.
Above disclosed is only the preferred embodiments of the utility model, and the power of the utility model cannot be limited with this
Sharp range, therefore equivalent variations made according to the claim of the utility model belong to the range that the utility model is covered.
