Background technology

Probe is a kind of connecting electronic component being commonly applied in Electronic Testing, most small volume and required precision is high, Production difficulty is larger；In practical application, generally require probe carries out path testing with connecting line cooperation, and the way for using at present is big All it is, through fixed plate, then connecting line projection to be milled to many connecting lines and is flushed with fixed plate, elastic probe passes through Tested with connecting line ends contact conducting in fixed plate after multiple jig plates, but the tool of high precision and fine pitch The elastic probe manufacture difficulty for being used is larger, and production cost is high, and after multilayer board architecture be connected thread end contraposition and is stranded Difficulty, tool manufacture difficulty is larger.

Utility model content

The technical problems to be solved in the utility model is, for the drawbacks described above of prior art, there is provided a kind of making side Just, low production cost and the easy line needle tubing of contraposition.

The utility model solves the technical scheme that its technical problem adopted：

Construct a kind of line needle tubing, including outer tube；Wherein, the syringe needle and spring being connected is provided with the outer tube；Also Including the connecting tube being connected with the outer tube, described connecting tube one end is connected with the outer tube, and the other end is connected with connecting line；Institute State syringe needle and be connected one end with the spring and be provided with connection boss；The outer tube is provided with first coordinated with the connection boss Spacing ring；The outer tube is additionally provided with the second spacing ring for the spring retainer with the connecting tube junction.

Line needle tubing described in the utility model, wherein, the outer tube is integrally formed with the connecting tube and is processed into.

Line needle tubing described in the utility model, wherein, the connecting tube is identical with the second spacing ring external diameter.

Line needle tubing described in the utility model, wherein, the syringe needle is concave away from the spring one end end face.

Line needle tubing described in the utility model, wherein, the connecting line wire body and connection inside pipe wall soldering connect.

The beneficial effects of the utility model are：During test, external probe is pushed with needle contact and is connected conducting, bullet Spring can be compressed, by the way that the first spacing ring is spacing to syringe needle, the second spacing ring is to spring retainer.External probe need not have bullet Property and have elasticity, greatly, external probe can also be arranged and oblique connect with syringe needle for external probe and needle contact range Touch, reduce high precision, the tool manufacture difficulty of fine pitch and cost, test convenient；Overall structure is simple, cost It is low.

Description of the drawings

In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below in conjunction with accompanying drawing and reality The utility model is described in further detail to apply example, and drawings in the following description are only the section Example of the present invention, for this For the those of ordinary skill of field, on the premise of not paying creative work, can be attached to obtain other according to these accompanying drawings Figure：

Fig. 1 is the line needle tubing structural representation of the utility model preferred embodiment；

Fig. 2 is the line needle tubing structural representation of another preferred embodiment of the utility model.

Specific embodiment

In order that the purpose of the utility model embodiment, technical scheme and advantage are clearer, below in conjunction with this practicality Technical scheme in new embodiment carries out clear, complete description, it is clear that described embodiment is portion of the present utility model Divide embodiment, rather than whole embodiments.Based on embodiments of the invention, those of ordinary skill in the art are not paying creation Property work on the premise of the every other embodiment that obtained, belong to protection domain of the present utility model.

The line needle tubing of the utility model preferred embodiment including being provided with outer tube 1, outer tube 1 as shown in figure 1, be connected Syringe needle 10 and spring 11；Also include the connecting tube 2 being connected with outer tube 1, the one end of connecting tube 2 is connected with outer tube 1, other end connection There is connecting line 3；Syringe needle 10 is connected one end with spring 11 and is provided with connection boss 100；Outer tube 1 is provided with and is connected boss 100 and matches somebody with somebody The first spacing ring 12 for closing；Outer tube 1 is additionally provided with as the second spacing spacing ring 13 of spring 11 with the junction of connecting tube 2；Test When, external probe is pushed with the ends contact of syringe needle 10 and is connected conducting, and spring 11 can be compressed, by the first spacing ring 12 to pin 10 spacing, the second spacing ring 12 is spacing to spring 11, and external probe need not have elasticity and elasticity of having, external probe It is big with the ends contact scope of syringe needle 10, external probe can also arrange it is oblique contact with syringe needle 10, reduce high precision, small The tool manufacture difficulty of spacing and cost, test convenient；Overall structure is simple, low cost.
