Abstract

The utility model discloses a kind of insertion spring, adopt the following technical scheme that include: ontology, its front end is equipped with interface, rear end is equipped with envelope curve portion, the interface is formed by its front end two sides by the gap between the intubation being bent to form and bottom surface, lock tongue is equipped among the bottom surface, the lock tongue is formed by opening up "u"-shaped groove on bottom surface, and the lock tongue is equipped with the lock point of protrusion.Advantage: being designed by lock bolt structure, elasticity more preferably, so that grafting is more smooth, and can grafting repeatedly.

Description

A kind of insertion spring

Technical field

The utility model relates to a kind of electronic component, specially a kind of slotting spring.

Background technique

Traditional slotting spring structure is by Patent No. " 201320606107.1 ", a kind of entitled " slotting spring end for preventing from swinging Shown in the Chinese utility model patent of son ", comprising: ontology, the front end is equipped with interface, rear end is equipped with envelope curve portion, described to insert Interface is formed by front end two sides by the gap between the intubation being bent to form and bottom surface.It is connected after male plug and slotting spring grafting to allow It is stronger, salient point or self-locking spring slice are set in slotting spring bottom surface, the self-locking spring slice is parallel by opening up two on bottom surface Fluting formed.Above-mentioned two kinds of self-locking structures have the drawback that: since salient point is nonelastic, self-locking spring slice is elastic poor, male plug When for the first time with slotting spring grafting, interface can be very tight, and male plug is difficult to be inserted into.But when repeating grafting, salient point or self-locking spring slice meeting It wears quickly, interface can fluff, and cause self-locking failure.

Utility model content

It is more smooth the technical problem to be solved by the present invention is to provide a kind of grafting and grafting is self-locking repeatedly to lose The insertion spring of effect.

To achieve the above object, the utility model adopts the following technical solution, comprising:

Insertion spring characterized by comprising

Ontology, front end is equipped with interface, rear end is equipped with envelope curve portion, and the interface passes through bent by its front end two sides At intubation and bottom surface between gap formed, lock tongue is equipped among the bottom surface, the lock tongue on bottom surface by opening up " U " Shape slot is formed, and the lock tongue is equipped with the lock point of protrusion.

The insertion spring, it is characterised in that: the lock point is low early and high after, and front end and bottom surface seamlessly transit.

The insertion spring, it is characterised in that: boss is formed on the bottom surface, the lock tongue is arranged on boss, The free end of the intubation is placed in above boss.

The insertion spring, it is characterised in that: the ontology corresponds to envelope curve portion front end and is equipped with gear line portion.

The insertion spring, it is characterised in that: the envelope curve portion is equipped with plastic sheath.

The insertion spring, it is characterised in that: the lock tongue is beloid, trapezoidal.

The insertion spring, it is characterised in that: the envelope curve portion is equipped with rib.

The insertion spring, which is characterized in that further include: male plug, front end are mating with the interface Plug division, the plug division are equipped with the lockhole with lock point cooperation.

The insertion spring advantage of the utility model: being designed by lock bolt structure, elasticity more preferably, so that grafting is more suitable It freely, and can grafting repeatedly.

The utility model is described in detail with reference to the accompanying drawing.

Specific embodiment

As shown in Figs 1-4, the insertion spring of the utility model, comprising: by the whole stamping forming ontology 1 of copper sheet, before End is equipped with interface 2, rear end is equipped with envelope curve portion 3, and the interface 2 passes through the intubation 4 being bent to form and bottom by its front end two sides Gap between face 5 is formed, and lock tongue 6 is equipped among the bottom surface 5, the lock tongue 6 is by opening up 7 shape of "u"-shaped groove in bottom surface 5 At the lock tongue 6 is equipped with the lock point 8 of protrusion, and the lock point 8 is integrally formed by punching press and lock tongue 6.

Further, the lock point 8 is low early and high after, and front end and bottom surface 5 seamlessly transit, and enables the smooth insertion of male plug, Play the role of retaining again simultaneously.

Further, be formed with boss 9 on the bottom surface 5, the lock tongue 6 is arranged on boss 9, the intubation 4 from 9 top of boss is placed in by end 10, the upper surface of the boss forms the contact surface with male plug, so that contacting with male plug more stable Reliably.

Further, corresponding 3 front end of envelope curve portion of the ontology 1 is equipped with gear line portion 11, and conducting wire is inserted into behind envelope curve portion 3, It is positioned by keeping off line portion 11, connects money to facilitate.

Further, the envelope curve portion 3 is equipped with plastic sheath 12, to play the use of protection and insulation.

Further, the lock tongue 6 is beloid, trapezoidal, to reach optimal elastic effect.

Further, further includes: male plug 13 matched with slotting spring, 13 front end of male plug are and 2 grafting of interface The plug division 14 of cooperation, the plug division 14 are equipped with the lockhole 15 with 8 cooperation of lock point.After the male plug is inserted into spring, insert The lock point of spring enters in the lockhole of male plug, locks to it.

Further, the front end of the plug division 14 is equipped with chamfering 16, can more smoothly be inserted into.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this Made any modifications, equivalent replacements, and improvements etc., is all contained in the protection of the utility model within novel spirit and principle Within the scope of.
