Description
【Technical field】
The present invention relates to connector technique field, specifically a kind of single needle self-locking self-unloading connector.
【Background technology】
In some specific places, it is often necessary to which it is a kind of convenient with plug to use, the single needle for the advantages of contacting reliable
Connector, according to the difference of pin hole locking mode, single needle connector common at present has contact engaging and separating force to lock single needle connector and card
Two kinds of pin locked single needle connector, contact engaging and separating force locking single needle connector is locked by the contact engaging and separating force between pin and hole, is used for
It is not subject to mechanical stress (such as vibration, impact, centrifugation, collision iso-stress) or mechanical stress very small place, this kind of product tool
Have the advantages that simple in construction, with low cost, have the disadvantage that mechanical resistant environmental stress ability is poor；Bayonet lock locking single needle connector is relied on
Bayonet lock spring is locked, with plug is convenient, contact is reliable, the place larger available for mechanical stress, and this kind of product, which has, inserts
Pull out conveniently, the advantage that contact is reliable, mechanical resistant stress performance is excellent, have the disadvantage parts machining complex process, such as laser welding,
Turning-milling complex processing etc., cost is higher.
Therefore, to overcome the shortcomings of that it is excellent that above-mentioned technology designs mechanical resistant stress performance, plug is convenient, and connection can
Lean on, while a kind of single needle self-locking self-unloading connector of cost, exactly inventor's problem to be solved can be reduced again.
【The content of the invention】
In view of the shortcomings of the prior art, it is an object of the invention to provide a kind of single needle self-locking self-unloading connector, the letter of its structure
Single, easy to operate, mechanical resistant stress performance is excellent, and plug is convenient, and connection is reliable, while can reduce cost again, there is very good
Practical value.
The technical solution adopted for the present invention to solve the technical problems is：A kind of single needle self-locking self-unloading connector, it includes
Hole is combined and pin combines two parts, and the hole combination is made up of hole body, contact spring, claw and protheca, and contact spring is arranged on hole
In the spring-holding hole of body, claw is arranged in the claw hole of protheca, is linked together between protheca and hole body using interference fit, is formed
Hole is combined, pin combination by needle body, sliding sleeve, slide back-up ring, spring, retaining back-up ring and jump ring and constitute, sliding sleeve, slide back-up ring,
Spring and retaining back-up ring are fitted together, and form a sliding bush combination, and sliding bush combination is enclosed on needle body tail end, and with jump ring by sliding sleeve
Combination is arranged on needle body, forms pin combination, and sliding bush combination can be slided on needle body.
Further, when connection is combined in the hole combination with pin, needle body contacts during the contact spring in the combination of hole is combined with pin
End in contact, realizes the conduction of electricity；The end face of claw Elastic Teeth supports needle body clamping boss side surfaces in pin combination in the combination of hole, from
And realize the connection that pin combination is combined with hole.
Further, the sliding bush combination by sliding sleeve, slide back-up ring, spring and retaining back-up ring and constitute, sliding back-up ring can be
Slide, when sliding back-up ring slip, compression spring is extruded on sliding sleeve.
Further, appearance spring groove and mating surface are designed with the hole body.
Further, indent in the middle of the contact spring, contact spring is flexible.
Further, protheca mating surface is designed with claw hole and protheca mating surface, protheca on the protheca with matching somebody with somebody on hole body
It is interference fit between conjunction face.
Further, Elastic Teeth is designed with the claw, Elastic Teeth indent is simultaneously flexible.
Further, contact jaw, clamping boss, jump-ring slot are designed with the needle body.
Further, it is designed with the sliding sleeve in the middle of solution lock station and retaining back-up ring fixed station, sliding sleeve and is provided with step.
Further, the diameter of bore for sliding back-up ring is more than the diameter of sliding sleeve intermediate step, and sliding back-up ring can be in cunning
Put slip.
The beneficial effects of the invention are as follows：
When the present invention promotes the sliding bush combination in pin combination, sliding sleeve will combine end motion to hole, when the solution lock station on sliding sleeve
When strutting the Elastic Teeth in hole combination claw, the Elastic Teeth on claw no longer supports the clamping boss side surfaces of needle body in pin combination,
Now, outwards light to draw pin combination, pin combination can deviate from from the combination of hole, realize the separation that pin combination is combined with hole, the present invention
Connector has excellent mechanical resistant stress performance, plug convenience, connection reliable, the advantages of with low cost.
