Abstract
A spring needle with a ball body comprises a needle tube, a needle shaft inserted in the needle tube and a spring arranged between the needle shaft and the needle tube. The end surface of the end of the needle shaft is an inclined surface. The outer circumferential surface of the lower part of the needle shaft forms an outer edge lug. A ball body is arranged between the end of the needle shaft and the spring. The lower part of the inner wall of the needle tube forms an inner edge lug. With the abovementioned structural design, the ball body is arranged between the needle shaft and the spring, and the strength of the spring is concentrated at one point, so that contact between the needle shaft and the spring is more reliable.
Description
Technical field
The utility model relates to connector technique field, particularly a kind of spring needle with ball bead.
Background technology
Spring needle is a kind of spring probe being formed by needle shaft, spring and three basic elements of character of needle tubing, is widely used in antenna for mobile phone, the connection function between battery of mobile phone etc. and cell phone mainboard.
Spring needle in the past comprises needle shaft, spring and needle tubing, and needle shaft inserts in needle tubing, between needle tubing and needle shaft, spring is installed, and needle shaft top is spherical shape, and the axle head end face that needle shaft end contacts with spring is inclined-plane.Because axle head end face is the side contacts that inclined-plane makes needle shaft and spring top, there is the problem of the dispersion of power in the spring needle of said structure, it is unreliable between needle shaft and spring, to contact between spring and needle shaft.
Therefore, prior art awaits providing and improving.
Summary of the invention
For the deficiencies in the prior art part, the purpose of this utility model is to provide a kind of concentrated spring dynamics, makes spring contact more reliably the spring needle with ball bead with needle shaft.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of spring needle with ball bead, comprise needle tubing, insert the needle shaft in needle tubing, be installed on the spring between needle shaft and needle tubing, the distal end faces of described needle shaft is inclined-plane, the external peripheral surface of described needle shaft bottom is formed with outer rim lug boss, is also provided with a ball bead between pin the tip of the axis and spring.
Preferably, described needle interior wall bottom is formed with inner edge lug boss.
Compared with prior art, the beneficial effects of the utility model are: by above-mentioned structural design, between needle shaft and spring, ball bead is set, the dynamics of spring converges, and make needle shaft and spring contact more reliable.
Accompanying drawing explanation
Accompanying drawing 1 is the profile of a kind of spring needle with ball bead of the utility model.
In figure, each label respectively: (1) needle tubing, (2) needle shaft, (3) spring, (4) outer rim lug boss, (5) ball bead, (6) inner edge lug boss.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Referring to Fig. 1, a kind of spring needle with ball bead of the utility model, comprise needle tubing 1, insert the needle shaft 2 in needle tubing 1, be installed on the spring 3 between needle shaft 2 and needle tubing 1, the distal end faces of described needle shaft 2 is inclined-plane, the external peripheral surface of described needle shaft 2 bottoms is formed with outer rim lug boss 4, between the end of needle shaft 2 and spring 3, be also provided with a ball bead 5, by above-mentioned structural design, the dynamics of spring is concentrated on the point that ball bead 5 contacts with needle shaft 2, make needle shaft 2 contact more reliable with spring 3.
Described needle interior wall bottom is formed with inner edge lug boss 6, and this inner edge lug boss 6 and outer rim lug boss 4 is moving to be contacted, and stop bit when descending to needle shaft 2.
In sum, the utility model, by above-mentioned structural design, solves the problem existing in conventional art, can concentrate spring dynamics, spring is contacted more reliable with needle shaft, can be widely used in the occasion of the large electric current of needs.
Certainly, the utility model also has other distortion.In a word, the apparent change of making according to the prompting of above-described embodiment, and other every changes that do not depart from the utility model essence, within all should being included in the scope described in claim.
Claims (2)
1. the spring needle with ball bead, comprise needle tubing, insert the needle shaft in needle tubing, be installed on the spring between needle shaft and needle tubing, it is characterized in that, the distal end faces of described needle shaft is inclined-plane, the external peripheral surface of described needle shaft bottom is formed with outer rim lug boss, is also provided with a ball bead between pin the tip of the axis and spring.
2. the spring needle with ball bead as claimed in claim 1, is characterized in that, described needle interior wall bottom is formed with inner edge lug boss.
