Abstract
The invention relates to a terminal block capable of preventing screws from looseness. The terminal block comprises the screws, hexagonal nuts, gaskets, a matrix and conducting pieces, a plurality of hexagonal blind holes are uniformly arranged on a surface layer of the matrix, the hexagonal nuts are exactly embedded in the hexagonal blind holes, the screws are matched with the hexagonal nuts, a crossed groove is arranged at the top of each screw, each screw is sprayed with half-cycle of nylon powder, the gaskets are sleeved on the screws, the conducting pieces are disposed on the hexagonal blind holes in pair, two circular holes are arranged on each conducting piece, the size of the circular holes is identical with the size of inner walls of the hexagonal nuts, and the circular holes on the conducting pieces and through holes arranged in the middle of the hexagonal blind holes are on a same axis. The nylon powder is sprayed on the screws to enable the screws and the nuts to generate strong friction force, so that the problem of looseness of the screws is solved.
Description
Technical field
The present invention relates to a kind of connecting terminal block that prevents that screw from getting loose.
Background technology
In the existing market, most connecting terminal block all is the mode that adopts the screw line ball, and this line ball mode is simply direct, easy operating, but there is a problem: because screw connects distinctive problem, cause that owing to operational environment is in vibrating state screw gets loose gradually after the locking.Will cause that like this contact resistance increases between wire harness and the current－carrying conductor, gradually heating in long-time running, can cause the thawing of terminal board basis material to be caved in after reaching terminal board basis material fusing point when serious, cause the phenomenon on fire that is short-circuited of colliding between the carrying object, cause fire, perhaps heating reaches after the material around ignition point, and material around occurs on fire, causes fire.
Summary of the invention
Technical problem to be solved by this invention provides and a kind ofly in use can prevent the connecting terminal block that screw gets loose.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a connecting terminal block, comprise screw, hex nut, pad, matrix and conducting strip, matrix comprises loam cake and base plate, on the top layer of base plate, opened uniformly some holes hexagon blind hole, the size of each hexagon blind hole is identical, hex nut just in time is embedded in the hexagon blind hole, intermediate open position in the hexagon blind hole is connected with a through hole that screw is stretched into, screw and hex nut match, top at screw has cross recess, be coated with the half cycle nylon powder on the screw, cover has pad on the screw, per two of hexagon blind hole is to be mounted with a conducting strip above one group, has opened two circular holes at conducting strip, and the size of circular hole is greater than the size of hex nut inwall, the through hole of opening in the middle of circular hole on the conducting strip and the hexagon blind hole is on same axle, and conducting strip is put well rear by being fixed on the base plate with loam cake.
Use above-mentioned device, be coated with nylon powder at screw, utilize the bounce-back of engineering resin material, make screw and nut in the locking process, produce powerful frictional force by the extruding engineering resin material, reach the absolute resistance to vibrations and impact, thereby solved the loosening problem of screw.
Description of drawings
Fig. 1 is the structural representation of connecting terminal block of the present invention.
Embodiment
By structural representation shown in Figure 1 as can be known, 1 is base plate, and 2 is conducting strip, and 3 is screw, and 4 is hex nut, and 5 is loam cake, and 6 is pad.
Matrix is comprised of base plate 1 and loam cake 5, eight hexagon blind holes have been opened on the top layer of base plate 1, the size dimension of each hexagon blind hole is identical, the through hole that screw 3 is stretched into is all opened in centre position in each hexagon blind hole, hex nut 4 just in time can be embedded in the hexagon blind hole, hex nut 4 matches with screw 3, one cross groove is arranged at the top of screw 3, at screw 3 covers one square pad 6 is arranged, per two of hexagon blind hole is one group, the upper end of every group of hexagon blind hole all is mounted with a conducting strip 2, two circular holes have been opened in the left and right sides on conducting strip 2, two circular holes of conducting strip 2 are on the same vertical pivot position with the through hole that open the middle part of hexagon blind hole respectively, and the circular hole on the conducting strip 2 is greater than the size of the inwall of hex nut 4, the size of the through hole that open the inwall of hex nut 4 and hexagon blind hole middle part is identical, circular hole and hex nut 4 that screw 3 passes on the conducting strip 2 are fixed, conducting strip 2 is stepped, have two to hold up chip in the middle part of conducting strip 2, loam cake 5 is installed in the upper end of conducting strip 2, and is fixedly connected with between loam cake 5 and the base plate 1.
