Technical field

The utility model is related to probe adapter technical field, relates more specifically to a kind of syringe needle plus insulated plastic formula probe Connector.

Background technology

With the progress and the development of technology of science and technology, such as digital camera, DV, laptop computer, mobile phone and PAD Swift and violent development has been obtained Deng portable digital product and has been widely applied.The power supply one that such portable digital product is used As be all rechargeable battery, and typically connected between battery and electrical equipment by probe adapter.

Fig. 1 and Fig. 2 are referred to, conventional probe adapter generally comprises needle shaft 10, inner tube 20 and spring 30, and spring 30 is filled Fit in the cavity 21 of inner tube 20, needle shaft 10 is riveted on inner tube 20 and contacted with spring 30.In use, needle shaft 10 is directly and power supply Contact, is used as electric power conduction；General mobile phone probe adapter requires that the resistance of probe adapter is relatively low, probe adapter Resistance has outside the Pass except the material with using, and also the contact area with needle shaft 10 and inner tube 20 has direct relation, the size of resistance It is inversely proportional with needle shaft 10 and the contact area of inner tube 20, i.e. the bigger resistance of contact area is smaller.Therefore, in order to increase needle shaft 10 with The contact area of inner tube 20, the end face beveling that needle shaft 10 is contacted with spring 30, the meeting in the presence of spring 30 of needle shaft 10 Generation eccentric motion, increase needle shaft 10 and the contact area of inner tube 20, that is, reduce the resistance between needle shaft 10 and inner tube 20 so that Probe adapter has more preferable electric connection.

But when in use, Multi-contact is formed between the meeting of needle shaft 10 moved into inner tube 20 and inner tube 20, so that shape Into a plurality of current conduction path so that easily signal interference occur when applying to the apparatus fields such as RF high frequencies, 5G, cause signal What is transmitted is unstable.Thus, to meet application of the probe adapter in apparatus fields such as RF high frequencies, 5G, in addition it is also necessary in existing skill Further technology extension is done in art and is expanded.

Utility model content

The purpose of this utility model is to provide a kind of syringe needle plus insulated plastic formula probe adapter, connected with probe is reduced The advantage of the current conduction path of device is connect, the application for making it be satisfied with the apparatus fields such as RF high frequencies, 5G.

Above-mentioned purpose of the present utility model technical scheme is that：A kind of syringe needle adds insulated plastic formula Probe adapter, including inner tube and the needle shaft for being riveted on said inner tube, the needle shaft include needle shaft body and are shaped in The end of the needle shaft body and external diameter, which are more than on the end seat of the external diameter of the needle shaft body, the needle shaft, is arranged with bottom abutting In the end seat and the insulation sleeve that is riveted with said inner tube, the needle shaft extends the insulation sleeve.

By using such scheme, in use, insulation sleeve is contacted with the inwall of inner tube will not form current conduction path, from And the conducting path conduction that electric current is formed from the contact by end seat with inner tube as much as possible, with reduction electric current conducting pathway The advantage in footpath, makes probe adapter meet the application of the apparatus fields such as RF high frequencies, 5G.

Preferably, the needle shaft body fits in the inwall of the insulation sleeve.

By using such scheme, needle shaft body fit in insulation sleeve inwall can effectively prevent other debris fall into by In the space that needle shaft body is formed with insulation sleeve.

Preferably, the insulation sleeve is plastic cement insulation sleeve.

By using such scheme, plastic cement has good electrical insulating property, and also has excellent acoustic attenuation performance.

Preferably, the end seat is flexible and end face of from the end seat caves inward wearing of forming that opening extends out Groove, the end face of the end seat, which is abutted, circular cone, and the end face of the circular cone is supported with the spring being placed in the cavity of said inner tube Connect.

By using such scheme, in use, needle shaft is moved into the cavity of inner tube so that circular cone is transported into wears groove It is dynamic, expand outwardly end seat so as to extrude end seat, and contacted with the inwall of inner tube, constitute current conduction path, and end seat with The larger face contact of contact surface is formed between inner tube, thus makes probe adapter that there is preferable electric connection.

Preferably, the wears groove is opened in the center of the end seat.

By using such scheme so that end seat is extended out uniformly when being extruded by circular cone, integrally.

Preferably, the end seat is beryllium copper end seat.

By using such scheme, beryllium copper has higher elasticity and electric conductivity.

In summary, the utility model has the advantages that：

First, being sheathed on the insulation sleeve outside needle shaft so that probe adapter when in use, the inwall of insulation sleeve and inner tube Contact will not form current conduction path, so that the conduction that electric current is formed from the contact by end seat with inner tube as much as possible Path, has the advantages that to reduce current conduction path, probe adapter is met answering for the apparatus fields such as RF high frequencies, 5G With；

Second, needle shaft body fits in insulation sleeve, fallen into other debris are effectively prevented by needle shaft body and insulation sleeve Effect in the space of formation；

Third, passing through the mutual cooperation of circular cone and end seat that is flexible and offering wears groove so that probe adapter When in use, end seat is expanded outwardly, and is contacted with the inwall of inner tube, so that current conduction path is constituted, and end seat and inner tube Between form the larger face contact of contact surface, it is ensured that probe adapter has preferable electric connection.
