Abstract
The invention discloses a contact pair with high separating force. The contact pair comprises an insertion pin and an insertion hole, wherein a conical lead angle and a ring groove are formed on the insertion pin; a flange and an opening are formed on the insertion hole; the insertion pin is inserted into the insertion hole through the conical lead angle; and the flange of the insertion hole is clamped in the ring groove of the insertion pin. By changing a connection structure of the insertion pin or the insertion hole, the pull-out force of the contact pair is obviously greater than insertion force, and the contact pair has the advantages of simple structure, convenience for operation and high connection reliability.
Description
Technical field
The present invention relates to technical field of electric connectors, especially a kind of contact of high separating force is right.
Background technology
The Elastic Contact of being made up of contact pin and jack is to being the vitals in the electric connector, and it bears the task of circuit turn-on in the connector.For improving the right connection reliability of contact; Through the syndeton that changes contact pin or jack improve contact between contact engaging and separating force; The open flume type elastic hole is a kind of common form that contact is made jack, example: No. eight of using of prior art connector contact to the minimum withdrawal force that provides as 1.5N about.In today of communications industry high speed development, be in loaded state or activity occasion for link, just needing to provide the contact of higher withdrawal force right.The problem that exists is, changes the syndeton of contact pin or jack, often cause contacting between contact engaging and separating force increase simultaneously; Cause contact that mating force is increased; Be unfavorable for on-the-spot fitting operation, how can not increase contact right mating force and only improve withdrawal force, neither influence is on-the-spot installs behaviour; Can improve the right connection reliability of contact again, be order of the present invention place.
Summary of the invention
The contact of a kind of high separating force that the objective of the invention is to be directed against the deficiency of prior art and provide is right.The present invention is through changing the syndeton of contact pin or jack, makes the right withdrawal force of contact obviously greater than mating force, have simple in structure, easy to operate, the advantage that connection reliability is high.
The concrete technical scheme that realizes the object of the invention is:
A kind of contact of high separating force is right; Its characteristics comprise contact pin and jack, and said contact pin is provided with socket cap, and the termination of socket cap is provided with the taper lead angle that angle is α; Said α angle is 30 ° ± 5 °; Radially be provided with annular groove on the socket cap, annular groove is provided with the chamfering that angle is β near a side of taper chamfering, and said β angle is 45 °～75 °; Jack is provided with cylindrical drum, and what radially be provided with flange, barrel in the cylindrical drum axially has several gap; Said contact pin is plugged in the jack through the taper lead angle, and the flange of jack is connected in the annular groove of contact pin.
The present invention is through changing the syndeton of contact pin or jack, makes the right withdrawal force of contact obviously greater than mating force, have simple in structure, easy to operate, the advantage that connection reliability is high.

Embodiment
Consult Fig. 1, Fig. 2, Fig. 3; The present invention includes contact pin 1 and jack 2, said contact pin 1 is provided with socket cap, and the termination of socket cap is provided with the taper lead angle 11 that angle is α; Said α angle is 30 ° ± 5 °; Radially be provided with annular groove 12 on the socket cap, annular groove 12 is provided with the chamfering that angle is β near a side of taper chamfering 11, and said β angle is 45 °～75 °; Jack 2 is provided with cylindrical drum, and what radially be provided with flange 21, barrel in the cylindrical drum axially has several gap 22; Said contact pin 1 is in taper lead angle 11 is plugged on jack 2, and the flange 21 of jack 2 is connected in the annular groove 12 of contact pin 1.
The present invention uses like this:
The grafting that Elastic Contact is right
Consult Fig. 1, Fig. 5; Elastic Contact is to being made up of contact pin 1 and jack 2, with several Elastic Contact on the plug and socket that is installed on connector respectively, when the plug of connector and socket plug together; Contact pin 1 is in taper lead angle 11 is plugged on jack 2; And the flange 21 of jack 2 is connected in the annular groove 12 of contact pin 1, realizes the right grafting of Elastic Contact, accomplishes the connection of connector simultaneously.
Elastic Contact is to grafting process and force analysis
Consult Fig. 5; Because the gap 22 on the cylindrical drum is separated to form several reeds with barrel, when contact pin 1 of the present invention inserts jack 2, apply an external force F
for contact pin 1; Make the conical surface of contact pin 1 upper conical lead angle 11 touch the flange 21 in the cylindrical drum; Under function of friction, force reed to open, with going deep into of contact pin 1; The annular groove 12 of contact pin 1 arrives at flange 21 positions of jack 2; Reed shrinks, and flange 21 is connected in the annular groove 12 of contact pin 1, and contact pin 1 inserts in the jack 2; Since the α angle of contact pin 1 taper lead angle 11 be 30 ° ± 5 ° when contact pin 1 insertion jack 2, the angle of friction between taper lead angle 11 and the flange 21 is little, the frictional resistance when causing inserting is little.
Elastic Contact is process and force analysis when extracting
Consult Fig. 4, when contact pin 1 of the present invention when jack 2 is extracted, apply an external force F
for contact pin 1; Make annular groove 12 sides on the contact pin 1 touch the flange 21 in the cylindrical drum; Under function of friction, force reed to open, with withdrawing from of contact pin 1; The annular groove 12 of contact pin 1 breaks away from flange 21 positions of jack 2; Reed shrinks gradually, breaks away from jack 2 until contact pin 1, and contact pin 1 is extracted from jack 2; Because the β angle of annular groove 12 sides is 45 °～75 °, when contact pin 1 when jack 2 is extracted, the angle of friction between annular groove 12 sides and the flange 21 is big, the frictional resistance when causing extracting is big; Thereby make the right withdrawal force of contact obviously greater than mating force, have simple in structure, easy to operate, the advantage that connection reliability is high.
