Abstract
The invention relates to a pin contact and an electric connector using the pin contact. The pin contact comprises a tubular contact matrix and a tail segment that is connected on the contact matrix integratedly. The contact matrix includes a guiding segment and a contact segment, wherein the guiding segment and the contact segment are successively arranged coaxially from front to back; and the contact segment includes over two elastic contact zones; moreover, one end of each of the elastic contact zone is connected to the guiding segment and the other end of each of the elastic contact zone is connected to the tail segment; and two ends of all the elastic contact zones are compressed to form arcs that are bulged outwardly along a radial direction of the contact matrix. According to the invention, a tubular contact matrix is employed by the pin contact and all the elastic contact zones are in arc shapes that are bulged outwardly along a radial direction of the contact matrix; therefore, when the corresponded pin contact is inserted, all the elastic contact zones are pushed from the top at an internal face of a jack contact so as to form a face-to-face contact; and thus, reliability of contact between the pin contact and the jack contact is enhanced and a problem that contact between a pin contact and a jack contact is not reliable in the prior art is solved.
Description
Technical field
The present invention relates to electric connecting element, especially a kind of contact pin contacting piece and use the electric connector of this contact pin contacting piece.
Background technology
Contact pin contacting piece and jack contact are parts commonly used on the connector, and existing contact pin contacting piece mostly comprises a wiring part and a grafting part, and the part of wherein pegging graft adopts the aciculiform post, and jack contact comprises a jack, is provided with elastic tongue piece in the jack; When jack contact and contact pin contacting piece are pegged graft, compress described contact pin contacting piece, thereby realize being electrically connected through the elastic tongue piece in the jack of said jack contact; Contact pin contacting piece and jack contact with said structure have obtained using widely in connector; But also there are some problems; At first; Because the restriction of jack contact structure, the elastic tongue piece that is arranged in its jack contacts with contact pin contacting piece multidigit point or the line contact, and this reliability that then makes contact pin contacting piece contact with jack contact is difficult to guarantee; Secondly; Because the Plug Division of said contact pin contacting piece is divided into the aciculiform post; Therefore must in the jack of jack contact, contact tongue be set, and contact tongue is made often in the jack that is assemblied in jack contact after the moulding, so complicate fabrication process; Increase the manufacturing process of contact, thereby increased the manufacturing cost of contact and connector; In addition, especially when connector need satisfy miniaturization, it is particularly difficult that the assembling between elastic tongue piece and the jack contact then seems.
Summary of the invention
The object of the present invention is to provide a kind of contact pin contacting piece, with solve existing contact pin contacting piece and jack contact when pegging graft owing to be some contact perhaps that line contacts the insecure problem of contact that causes.
In order to address the above problem; Said contact pin contacting piece adopts following technical scheme: contact pin contacting piece; The contact matrix and the one that comprise tubulose are connected in the rear on the said contact matrix; Said contact matrix comprises in the past backward the boot segment of coaxial setting and contact-segment successively, and said contact-segment comprises two above Elastic Contact bands, and an end of said each Elastic Contact band is connected on the described boot segment; The other end is connected on the described rear, and each Elastic Contact band forms the arc of radially outward heaving along the contact matrix through the two ends pressurized.
Said contact-segment is provided with two above slotted holes, and two narrow sides of each slotted hole extend to respectively on said boot segment and the rear, forms described Elastic Contact band between adjacent two slotted holes.
Said each slotted hole is distributed on the described contact-segment around the axis of contact matrix.
The coaxial binding post that is fixed with on the said rear.
The front end face of said boot segment is provided with the breach that caves in backward along the axis of contact matrix, and the front end of boot segment is to the inner bending of contact matrix and form cambered surface.
Said electric connector adopts following technical scheme: electric connector; Comprise insulator and fixedly be assemblied in the contact pin contacting piece in the said insulator; Said contact pin contacting piece comprises that the contact matrix of tubulose and one are connected in the rear on the said contact matrix; Said contact matrix comprises in the past backward the boot segment of coaxial setting and contact-segment successively, and said contact-segment comprises two above Elastic Contact bands, and an end of said each Elastic Contact band is connected on the described boot segment; The other end is connected on the described rear, and each Elastic Contact band forms the arc of radially outward heaving along the contact matrix through the two ends pressurized.
Said contact-segment is provided with two above slotted holes, and two narrow sides of each slotted hole extend to respectively on said boot segment and the rear, forms described Elastic Contact band between adjacent two slotted holes.
Said each slotted hole is distributed on the described contact-segment around the axis of contact matrix.
The coaxial binding post that is fixed with on the said rear.
The front end face of said boot segment is provided with the breach that caves in backward along the axis of contact matrix, and the front end of boot segment is to the inner bending of contact matrix and form cambered surface.
Because said contact pin contacting piece adopts the contact matrix of said tubulose and said contact matrix to be provided with described boot segment and contact-segment; Have two above-described Elastic Contact bands on the said contact-segment; Said each contact zones all are the arc of radially outward heaving along the contact matrix; Therefore when inserting corresponding jack contact; Said each Elastic Contact band generation elastic deformation and firmly roof pressure on the internal face of jack contact, thereby the contact of formation face-face has increased the reliability that contact pin contacting piece contacts with jack contact; Because the two ends of said Elastic Contact band are connected on described boot segment and the rear; The length of increase Elastic Contact band that therefore can be suitable and can not increase the radial dimension of contact, this has then increased the contact area between contact pin contacting piece and the jack contact, further increases the reliability of contact; Existing contact pin contacting piece and jack contact have been solved owing to being to contact or the insecure problem of contact that the line contact causes.
