Abstract
The invention relates to the field of electrical connectors, in particular to a jack contact for electrical connectors and contact units thereof. The jack contact comprises a conducting sleeve; the front of the conducting sleeve is provided with a plug hole; at least one contact unit is arranged inside the plug hole; each contact unit comprises a fixing sleeve coaxial with the plug hole and a cantilever spring claw which is arranged at the front end of the fixing sleeve. The fixing sleeve is in interference fit with the conducting sleeve. A clearance is arranged between the back of the spring claw and the wall of the plug hole. Therefore, signals can be transmitted through contact between the contact units and fitting pins; when the spring claw damages, only the corresponding contact units need to be removed and replaced; the problem of waste on jack contacts can be solved; maintenance efficiency of electrical connectors is improved.
Description
Technical field
The present invention relates to electric connector field, particularly relate to a kind of for the jack contact in electric connector and contact monomer thereof.
Background technology
Along with the continuous expansion in function and model of electric connector, the kind being applied to the contact of electric connector is also day by day extensive.Jack contact is the general name of all kinds of female mouth contact, and it is mainly used for contact pin contacting piece grafting to realize the conducting to related circuit.
At present, common in electric connector field jack contact mainly contains wire spring type jack contact and split thimble composite type jack contact etc.Wherein the box-like jack contact of split thimble is low with its cost, volume is little and advantages of simple structure and simple is widely used.The box-like jack contact of split thimble comprises a caudal peduncle and a guide pin bushing, the front end of caudal peduncle has bullet pawl that extend forward, that define cantilever structure, the front end playing pawl adopts closing-in structure, guide pin bushing be enclosed within caudal peduncle front portion and by described bullet pawl casing wherein, play in the closing-in structure that surrounds of pawl to adaptive contact pin be introduced smoothly, turn edge in the front end place of guide pin bushing is also provided with structure.When contact pin adaptive with it inserts from front end, contact pin guides to and plays in closing-in structure that pawl surrounds by guide pin bushing, plays pawl and then press tactile by closing in place of its front end with contact pin, thus complete the conducting to related circuit.
Known by analyzing above, because bullet pawl is directly arranged on caudal peduncle, after use after a while, the meeting generation fatigue deformation playing pawl unavoidable is even ruptured, and this kind of situation is once occur, just can directly cause the whole of whole jack contact to scrap, causing a large amount of wastes does not say, also can waste the more time to the replacing of the jack contact broken down, affect the production efficiency of relevant device.In addition, the contact of above-mentioned split thimble composite type jack contact operationally and between adaptive contact pin is actually individual pen line contact, therebetween contact area is extremely limited, and therefore, split thimble composite type jack contact can not be applied to powerful occasion.
Summary of the invention
The object of the present invention is to provide a kind of jack contact, to solve the waste problem of jack contact, improve the maintenance efficiency to electric connector.
Meanwhile, the present invention also aims to the contact monomer that this jack contact is provided.
In order to solve the problem, jack contact is by the following technical solutions: jack contact, comprise conductive casings, the front portion of conductive casings has the spliced eye inserted for adaptive contact pin, at least one contact monomer is provided with in spliced eye, contact monomer comprises a fixed cover be coaxially set with spliced eye and is located at fixed cover front end place, cantilevered spring pawl, interference fit between fixed cover and conductive casings, has and dodge gap between the back side of spring pawl and the hole wall of spliced eye.
The front portion of described spring pawl is provided with the contact structures protruded to the inside.
Be formed with the step surface of face forward between the contact spring pawl back side of monomer and the outer peripheral face of fixed cover, described in dodge gap and formed by the difference in height contacted between the spring pawl back side of monomer and the outer peripheral face of fixed cover.
Described contact monomer has two or more, and the spring pawl being arranged in of rear in adjacent two contact monomers stretches to the fixed cover of that is positioned at front, has and dodge gap between the back side of spring pawl and corresponding fixed cover.
Contact monomer by the following technical solutions: contact monomer, comprise fixed cover and be located at fixed cover front end place, cantilevered spring pawl, the periphery of fixed cover has for the mating surface with corresponding conductive casings interference fit.
The front portion of described spring pawl is provided with the contact structures protruded to the inside.
The step surface of face forward is formed between the spring pawl back side of contact monomer and the outer peripheral face of fixed cover.
Interference fit owing to contacting between the fixed cover of monomer and conductive casings, have between the back side of spring pawl and the hole wall of spliced eye and dodge gap, therefore, contact with adaptive contact pin the transmission carrying out signal when in use by contact monomer, when spring pawl damages, only need to change contacting monomer taking-up accordingly, thus the waste problem of jack contact can be solved, improve the maintenance efficiency to electric connector.
Further, inner convexed contact structures on spring pawl can ensure the contact reliability with adaptive contact pin further, simultaneously, only contact structures are convex type structure, also contact structures part formation unexpectedly relative thin weak part can be made, be easy to flexural deformation, thus forming surface between contact structures with adaptive contact pin is contacted; Plural contact monomer is that (jack is generally radial dimension and is subject to strict restriction for axial space in order to make full use of jack contact, axially generally there are the actual conditions in larger leeway), increase the contact area with adaptive contact pin to greatest extent, improve the through-put power of jack contact.
