Abstract
The invention relates to a scale type elastic reed insertion hole which comprises an insertion hole casing and a crowned spring contact part arranged in the insertion hole, wherein the contact part comprises two end retaining rings and a middle retaining ring positioned between the two end retaining rings and provided with a ring-shaped protrusion. A ring-shaped groove corresponding to the ring-shaped protrusion is formed along the inner wall of the insertion hole casing, and a crowned spring wire is arranged between the middle retaining ring and each end retaining ring, enables the middle retaining ring to be connected with the end retaining ring, and is provided with two or more elastic adduction portions. By means of the scale type elastic reed insertion hole, scattered transmission of current can be achieved, contact resistance is decreased, current-carrying capability and reliability are improved, and abuse resistance of the insertion hole can be improved.
Description
Technical field
The present invention relates to connector technique field, be specifically related to a kind of flake type elastic spring jack.
Background technology
Contact pin and jack are the vitals for transmission current or signal in connector, in use, the bonding wire end of contact pin and jack is provided with cable, contact pin is plugged in jack and with jack and is electrically connected, realize the switching of the signal on cable, for contact pin and jack can be reliably electrically connected, those skilled in the art can arrange hat spring conventionally in jack, conventional hat spring generally comprises the fixing ring at two ends, between two fixing rings, be provided with hat spring silk, the two ends of hat spring silk are connected with the fixing ring at two ends respectively, in the middle part elasticity of hat spring silk, receive, whole hat spring is hyperboloid type, hat spring is fixedly installed in jack, the fixing ring of hat spring is close in jack and contacts and be electrically connected with the inwall of jack, in the time pegging graft, contact pin contacts and hat spring silk is strutted with the part of receiving in the elasticity of hat spring silk middle part, thereby realize being reliably electrically connected of contact pin and jack.When long the and contact pin of the plug-connection section that mutually plugs together when contact pin and jack and jack need to have multiple contact point, two hat springs will be set in jack, two hat springs are arranged in parallel by intermediate member, as shown in Figure 1, two strings of a hat (2 ') are arranged in parallel in jack housing (1 '), and the jack part of this kind of structure is comparatively complicated, and assembly difficulty is larger, especially that string of a hat (2 ') inside, is likely stuck in the position of that string of a hat (2 ') of outer portion.And because contact pin is subject to the support of two points in the string of a hat (2 '), may be due to unbalance stress, cause contact resistance difference, cause the inhomogeneous of traffic load electric current, finally cause in succession burning of two strings of a hat (2 ').
Summary of the invention
The object of the invention is the deficiency for solving the problems of the technologies described above, a kind of flake type elastic spring jack is provided, can realize electric current and disperse transmission, reduce contact resistance to improve current capacity and reliability, can improve the resistance to abuse ability of jack simultaneously.
The present invention is the deficiency solving the problems of the technologies described above, the technical scheme adopting is: a kind of flake type elastic spring jack, comprise jack housing and be arranged on the hat spring contact in jack housing, described contact comprises two end fixing rings and the middle part fixing ring between two end fixing rings, described middle part fixing ring has an annular projection, jack housing is provided with the annular recess corresponding with this annular projection along inwall, between middle part fixing ring and two end fixing rings, be respectively arranged with one group of hat spring silk that middle part fixing ring and corresponding end fixing ring are linked up, described hat spring silk all has receipts portion at least two elasticity.
Described hat spring contact is C shape hat spring contact.
On described every root cap spring silk, be equipped with receipts portion in two elasticity.
beneficial effect
Flake type elastic spring jack of the present invention, can realize electric current and disperse transmission, reduces contact resistance to improve current capacity and reliability, can improve the resistance to abuse ability of jack simultaneously.
