Abstract

A fuse socket is provided with a pair of identical inserting spring sheets. Each inserting spring sheet includes a tail, a base and a clamping portion which are sequentially connected from bottom to top; each clamping portion is forked into a pair of elastic arms, namely a left elastic arm and a right elastic arm; an upper projecting contact surface and a lower projecting contact surface are manufactured on the inner surface of the left elastic arm; and a middle projecting contact surface manufactured on the inner surface of the right elastic arm is correspondingly arranged between the upper projecting contact surface and the lower projecting contact surface. The fuse socket with simple structure is applicable to a PCB.

Description

Fuse receptacle

Technical field

The utility model relates to a kind of appliance socket, refers in particular to a kind of fuse receptacle.

Background technology

Chinese patent once disclosed a kind of " pull-out fuse socket " (China, notification number CN2184253Y, November 30 1994 day for announcing), be one-body molded, the outer T font that forms, there is vertically vertical cave arranged side by side inside, can hold terminal, there is the bullet piece and the retaining edge of protrusion the two side in the cave, is used for fixing terminal, and vertical cave front end has bead to locate the terminal insertion depth, the socket rear end has lateral trench to communicate with vertical cave, the socket front end has semicircle breach to communicate with vertical cave, can insert fuse, but fuse is decided in the edge clipping clamping embedding of socket front end both sides.

Chinese patent once disclosed a kind of " dual fail-safe silk socket structure-improved " (China, notification number CN201207363Y, March 11 2009 day for announcing), include: pedestal, be provided with block set, inner both sides of block set and bottom position are respectively equipped with arculae electrode and cover ring electrode, and this arculae electrode and cover ring electrode combine with two fuses and constitute electric connection, and this cover ring electrode periphery ring is provided with lamellar body; The lock seat is socketed in the block set of this pedestal, and this lock seat is provided with two trepannings that can insert fuse, and the rear end is provided with at least one prominent point; Cover plate is provided with the embedding hole corresponding to this prominent point, and cover plate combines by described embedding hole and prominent point with the lock seat; Wherein: the lamellar body stage casing of this cover ring electrode is provided with the sincere curved face part of aduncate folder, and when fuse inserted, formation face contacted between cover ring electrode and the fuse.

Chinese patent once disclosed a kind of " automobile fuse box and fuse plugboard thereof " (China, notification number CN201323172Y, October 7 2009 day for announcing), the box body that this fuse box comprises the fuse plugboard, is plugged in fuse and the relay on the fuse plugboard and is used to accommodate the fuse plugboard.Described fuse plugboard comprises circuit board and is plugged in conducting terminal on the circuit board, and each conducting terminal comprises base portion, and from the elastic arm that base portion extends, the elastic arm end protrudes out the formation clamping part relatively.

Above-mentioned first and second fuse receptacle complex structure that patent is described, the cost height is not suitable for pcb board yet.The conducting terminal (being fuse receptacle) that above-mentioned the 3rd patent described can be applicable to pcb board, but its elastic arm design is unreasonable, and the phenomenon of loose contact often appears in clamping fuse pin, and is difficult to reach the requirement to contact engaging and separating force.

Summary of the invention

The purpose of this utility model is to provide a kind of fuse receptacle, and it is simple in structure, is applicable to pcb board.

For achieving the above object, solution of the present utility model is: a kind of fuse receptacle, it has a pair of identical plug in reed, each plug in reed is connected to afterbody, base portion and clamping part from bottom to up successively, the clamping part bifurcated is that a pair of elastic arm is left elastic arm and right elastic arm, left side elastic arm inner surface is shaped on epirelief contact-making surface and following protruding contact-making surface, and right elastic arm inner surface is shaped on the convexity contact-making surface, and the convexity contact-making surface is corresponding to the epirelief contact-making surface with down between the protruding contact-making surface.

Afterbody is fixed on the pcb board, the pin of a pair of elastic arm clamping fuse (electronic component).This fuse receptacle is a pair of identical plug in reed, and simple in structure, cost is low, and it is little to occupy the space on pcb board.Because, each plug in reed left side elastic arm inner surface is shaped on epirelief contact-making surface and following protruding contact-making surface, right elastic arm inner surface is shaped on the convexity contact-making surface, the convexity contact-making surface is corresponding to the epirelief contact-making surface with down between the protruding contact-making surface, with fuse (electronic component) pin contact-making surface three places are arranged, guaranteed the reliability of contact, its contact engaging and separating force has also satisfied designing requirement.
