Abstract
A novel spring needle is disclosed, comprising a needle tube, a needle shaft and a spring, wherein the needle shaft is inserted into the needle tube, the spring is mounted between the needle shaft and the needle tube, the needle shaft is shaped as a ball body, an elastic contact part of the spring and the needle shaft is provided with an arc groove which is matched with the ball body, and the outer circumferential surface of the needle shaft is wrapped and covered with a smooth layer. Through the above structural design which is characterized by adoption of the ball body-shaped needle shaft, when side force is applied on the upper part of the needle shaft, the needle shaft can roll and press downwards, and the phenomenon that the needle shaft is abutted against the needle tube and therefore the needle shaft cannot slide downward can be prevented.
Description
Technical field
The utility model relates to precision connector technical field, and specifically, it is a kind of novel spring needle.
Background technology
Spring needle is a kind of spring probe, is widely used in antenna for mobile phone, the connection function between battery of mobile phone etc. and cell phone mainboard.
Traditional spring needle is made up of needle shaft, spring and needle tubing, and needle shaft inserts in needle tubing, between needle tubing and needle shaft, spring is installed.In the time that the top of needle shaft is subject to side force, needle shaft props up a side inwall of needle tubing, causes needle shaft not glide, and affects the normal work of probe.
Therefore, prior art needs to be improved and improves.
Summary of the invention
For overcoming the deficiencies in the prior art part, the purpose of this utility model is to provide a kind of novel spring needle that guarantees that needle shaft still can normally be worked in the time bearing side force.
The utility model is realized above-mentioned purpose by following technological means:
A novel spring needle, comprises needle tubing, needle shaft and spring, and needle shaft inserts in needle tubing, between needle shaft and needle tubing, spring is installed; Described needle shaft is ball bead.
Preferably, described spring and needle shaft elastic connecting synapsis are provided with arc groove, and this arc groove and ball bead are suitable.
Preferably, the external peripheral surface of described needle shaft is coated with a smooth layer.
Compared with prior art, the beneficial effects of the utility model are: by above-mentioned structural design, adopt the needle shaft of ball bead shape, while making the top of needle shaft be subject to side force, can realize rolls presses down, and there will not be needle shaft to prop up the phenomenon that needle tubing causes needle shaft not glide.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
In figure, each label respectively: (1) needle tubing, (2) needle shaft, (3) spring, (4) arc groove, (5) smooth layer.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Referring to Fig. 1, a kind of novel spring needle of the utility model, comprises needle tubing 1, needle shaft 2 and spring 3, and needle shaft 2 inserts in needle tubing 1, between needle shaft 2 and needle tubing 1, spring 3 is installed; Described needle shaft 2 is ball bead, because needle shaft 2 is ball bead, in the time that the top of needle shaft 2 is subject to side force, between needle shaft 2 and spring 3, realizes rolling Elastic Contact, and the situation that there will not be needle shaft 2 not glide guarantees that it normally works.
Described spring 3 is provided with arc groove 4 with needle shaft 2 elastic connecting synapsis, and this arc groove 4 is suitable with ball bead; And the external peripheral surface of described needle shaft 2 is coated with a smooth layer 5, all can improve moving cooperation the between needle shaft 2 and spring 3 and needle tubing 1, the life-span of improving product.
In sum, the utility model, by above-mentioned structural design, solves the problem existing in conventional art, can be widely used in spring needle in the occasion that need to bear side force, has extensively positive practicality.
Certainly, the utility model also has other distortion.In a word, the apparent variation 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.
