Abstract
The prevent invention relates to a sectional tubular elastic contact for an electric coupler socket, which comprises an upper frame and a lower frame (1 and 4) and a lattice tube wall between the upper and the lower frame. Wherein, a concave arch is positioned at center of the lattice tube wall. The lattice tube wall is composed of oblique and parallel elastic contact strips (2). The elastic contact strip (2) is provided with an inwards convex arch. A cross section of the concave arch at center of the tube wall is hyperbolic. Based on the present invention, as a plug adapts to a socket, at least two to three points of a vertical line on a cylinder of a plug post or a contact pin of the plug contact the contact strip. Moreover, each elastic contact strip is provided with two points contacting the cylinder of the plug post or the contact pin at least, thus increasing contact quantity, ensuring stable and reliable electric connection performance and prolonging mechanical life.
Description
Technical field
The present invention relates to electric connector. the especially improvement of the elastic contact head in the electric connector socket.
Background technology
The prior art electric connector is made up of plug, socket two parts, and the contact head in the socket is provided with at least two upright elastic contact chips to contact with the inserting column of plug or contact pin and realize the transmission of the electric power or the signal of telecommunication.Common practices is radian to be arranged with elastic contact chip is curved, makes distance between relative two contact chip arcs top be slightly less than the diameter of inserting column or contact pin, to make every effort to every contact chip and inserting column or contact pin maintenance excellent contact.Yet because processing or assembly precision restriction, the layout of each elastic contact chip is not and is one to justify accurately, can cause certain sheet or a few contact chips not to keep excellent contact with inserting column or contact pin, and have only a point to contact on the straight line of every contact chip and the cylinder of inserting column or contact pin, above-mentioned factor all might cause contacting instability and lossing signal, or monolithic contact chip current-carrying is excessive and produce sparking, burns to connect the contact and product is scrapped too early.
Summary of the invention
The purpose of this invention is to provide the Elastic Contact contact head in a kind of electric connector socket that has stable, reliable electrical connection properties and grow mechanical endurance.
For achieving the above object, the present invention adopts following technical scheme: the elastic contact head in a kind of electric connector socket, be the pipeline section shape, have edge up and down and grid shape tube wall, it is characterized in that the grid shape tube wall that the middle part is cancave cambered surface is made up of oblique and the elastic contact chip that makes that is parallel to each other.
The cross section of above-mentioned elastic contact chip is inside convex globoidal.
The longitudinal section of the cancave cambered surface at above-mentioned tube wall middle part is a hyperbola.
Because being the grid shape tube wall of cancave cambered surface in the technique scheme in the middle part of the tube wall is made up of oblique and the elastic contact chip that makes that is parallel to each other, when plug, when socket engages, have at least 2-3 point to contact on the vertical curve of the inserting column of plug or contact pin cylinder with elastic contact chip, every elastic contact chip has at least 2 points to contact with inserting column or contact pin cylinder simultaneously, contact point quantity increases, guaranteed stable, reliable electrical connection properties, the prolonged mechanical life-span.

Embodiment
Describe embodiments of the invention in detail below in conjunction with accompanying drawing.
As shown in drawings, elastic contact head in this electric connector socket, become have edge 1,4 and the tiltedly shape of grizzly bar up and down shown in Figure 1 by the elastic copper sheet punching out, both one punch formings are wound into the pipeline section shape again, oblique grizzly bar tube wall middle part therebetween is cancave cambered surface, the longitudinal section of this cancave cambered surface is a hyperbola, as shown in Figure 2, and certainly, also can be other curve, as circular arc line, parabola etc.Tiltedly grid shape tube wall is made up of oblique and the elastic contact chip 2 that makes that is parallel to each other, and has interval 3 between per two elastic contact chips 2.Elastic contact chip 2 punching out become inside convex globoidal, and its cross section passes in and out in order to contact pin 5 as shown in Figure 3.As can be seen from Figure 5, because elastic contact chip 2 arranged askew, the present invention is after contact pin 5 inserts contact head, contact head be positioned at hyperbolic bank top near have 3 elastic contact chips 2 to contact with a vertical line of contact pin 5 cylinders, same elastic contact chip 2 another one contact point at least in addition contacts with another vertical line of contact pin 5 cylinders; The inclination angle of elastic contact chip 2 is big more, and contact point is many more, generally is advisable with 30 °-75 ° in the inclination angle.
Claims (2)
1, the elastic contact head in a kind of electric connector socket, be the pipeline section shape, has edge (1 up and down, 4) grid shape tube wall and therebetween, the middle part is the grid shape tube wall of cancave cambered surface and is made up of oblique and the elastic contact chip (2) that makes that is parallel to each other, and it is characterized in that the cross section of elastic contact chip (2) is inside convex globoidal.
2, the elastic contact head in the electric connector socket according to claim 1 is characterized in that the longitudinal section of the cancave cambered surface at tube wall middle part is a hyperbola.
