Abstract
The invention discloses a contact element free from being closed up. The contact element comprises an insertion hole and a contact pin; an inner hole is formed in the insertion hole; an arc-shaped inner bevel is arranged at the port of the inner hole; the contact pin is provided with a contact end; a semicircular head is arranged at the head part of the contact end, a small hole is formed in the axle center, a plurality of expansion grooves communicated with the small hole are formed in the radial direction, and a raised contact area is arranged in the radial direction of the semicircular head; the contact end of the contact pin is inserted in an inner hole of the insertion hole; the raised contact area of the semicircular head of the contact pin and the inner hole of the insertion hole allow the contact pin and the insertion hole to be electrically connected. According to the invention, the elastic contact pin provided with the expansion grooves and the semicircular head and the insertion hole provided with the inner hole are adopted to replace the traditional contact pin and insertion hole, so that the steps of closing up, aging, screening and the like of slotting can be eliminated, and the contact element has the advantages of simple structure, reliability in contact, and good conducting effect.

Technical field
The present invention relates to technical field of electric connectors right with contacting of socket for conduction plug, especially a kind of contact of exempting from mouth, the present invention is applicable to the contact of contact pin contact jaw diameter greater than 1mm.
Background technology
At present, follow the development of electronics technology, electric connector is widely used.Contact as the electric connector core parts is used widely equally in electric connector.Prior art fluting jack contact and integral structure, have good anti-vibration, impact resistance, is used widely in the fields such as communication, Aeronautics and Astronautics.The problem that exists is, such jack contact need closing in, timeliness, hang separating force, and complex procedures,, owing to affect jack separating force many factors, finally can only, by detecting, come into operation screening qualified product.
Summary of the invention
A kind of contact of exempting from mouth that provides for the deficiencies in the prior art is provided, the present invention adopts the jack that is provided with the elastic contact pin of telescopic chute, cup head and is provided with endoporus, replace traditional contact pin and jack, saved the steps such as closing in, timeliness, screening of grooved bore, have advantages of simple in structure, contact is reliable, conducting is effective.
The concrete technical scheme that realizes the object of the invention is:
A kind of contact of exempting from mouth, it is characterized in that it comprises jack and contact pin, described jack is that an end is provided with endoporus, the other end and is provided with the column of jack caudal peduncle, the port of its endoporus is provided with the interior chamfering of circular arc, the external diameter of column is provided with the jack step, contact pin is that an end is provided with contact jaw, the other end and is provided with the column of contact pin caudal peduncle, the external diameter of column is provided with the contact pin step, the head of contact jaw is provided with cup head, axle center and is provided with aperture, radially is provided with the telescopic chute that several and aperture connect, and cup head radially is provided with the contact zone of projection; The contact jaw of described contact pin is plugged in the endoporus of jack, and the contact zone of contact pin cup head projection and the endoporus of jack are with contact pin and jack conducting.
The present invention adopts the jack be provided with the elastic contact pin of telescopic chute, cup head and be provided with endoporus, replaces traditional contact pin and jack, has saved the steps such as closing in, timeliness, screening of grooved bore, have advantages of simple in structure, contact reliably, conducting is effective.

Embodiment
consult Fig. 1, Fig. 2, Fig. 3, a kind of contact of exempting from mouth, it is characterized in that it comprises jack 1 and contact pin 2, described jack 1 is that an end is provided with endoporus 12, the other end is provided with the column of jack caudal peduncle 14, the port of its endoporus 12 is provided with the interior chamfering 11 of circular arc, the external diameter of column is provided with jack step 13, contact pin 2 is that an end is provided with contact jaw 25, the other end is provided with the column of contact pin caudal peduncle 27, the external diameter of column is provided with contact pin step 26, the head of contact jaw 25 is provided with cup head 22, axle center is provided with aperture 21, radially be provided with the telescopic chute 24 that several and aperture 21 connects, and cup head 22 radially is provided with the contact zone 23 of projection, the contact jaw 25 of described contact pin 2 is plugged in the endoporus 12 of jack 1, and the contact zone 23 of contact pin 2 cup head 22 projections and the endoporus 12 of jack 1 are with contact pin 2 and jack 1 conducting.
Further illustrate as follows to design and application of the present invention:
Consult Fig. 1, the jack caudal peduncle 14 of several jacks 1 is located in socket, and by jack step 13 and socket location; The contact pin caudal peduncle 27 of several contact pins 2 is located in plug, and by contact pin step 26 and plug location; When plug and socket are pegged graft, namely realize several contact pins 2 respectively with the conducting of several jacks 1.
Consult Fig. 1, the contact jaw 25 of contact pin 2 is plugged in the endoporus 12 of jack 1, and the contact zone 23 of contact pin 2 cup head 22 projections and the endoporus 12 of jack 1 are with contact pin 2 and jack 1 conducting.
Consult Fig. 1, Fig. 2, Fig. 3, due to contact zone 23 external diameters of the cup head 22 projections endoporus 12 greater than jack 1, after docking, the surface of contact pin 2 contact zones 23 is subject to the positive pressure of jack 1 endoporus 12 hole walls, force the cup head 22 of contact pin 2 along telescopic chute 24 distortion, aperture 21 towards axle center closes up, after contact pin 2 inserts 1, under the elastic force effect of contact pin 2 telescopic chutes 24, the contact zone 2 of cup head 22 projections) in the interior generation normal pressure of the endoporus 12 of jack 1, guarantee to have reliable separating force between contact pin 2 and jack 1, realize current lead-through.
The design of contact normal pressure of the present invention and separating force;
The calculating of normal pressure:
E-elasticity modulus of materials;
I
-cantilever bending inertia;
Y-cantilever deflection amount;
L-contact zone is to the distance of fluting root.
The calculating of separating force:
N-fluting number;
μ-friction factor.
Peg graft smoothly for ease of jack 1 and contact pin 2, the present invention is provided with the interior chamfering 11 of circular arc at the port of jack 1 endoporus 12, when the cup head 22 of contact pin 2 inserts the endoporus 12 of jack 1, plays guide effect.
