Plastic sealed midget universal relay is during organization of production, traditional structure is that four fairleads are set on base plate, being used for the pin of pedestal and the leading foot of dynamic and static spring terminal installs, due to pin and leading foot all thinner, intensity is not high, in installation process, it is bad a little that the assembly precision of base plate and pedestal is controlled, just easily cause pin and (or) the leading foot dress do not enter or fracture, bending and the phenomenon of corrupted.
In addition, base plate and shell are all to adopt the injection molding moulding, and its overall dimension tolerance is larger, and rectangular base plate is when packing shell into, the dimensional fits of base plate and shell is had relatively high expectations, and this just causes, and assembly difficulty is large, assembling speed is slow, production efficiency is low and easily produce product rejection.
Summary of the invention
For the deficiency that prior art exists, the utility model provides a kind of midget universal relay, can realize quick assembling, production efficiency is high, assembly qualified rate of product is high, better meets need of production.
For achieving the above object, the utility model provides following technical scheme:
Described a kind of midget universal relay, adopt plastic package structure, comprise pedestal, quiet spring terminal, moving spring terminal, coil pin, shell and base plate, two coil pins, a moving spring terminal and a quiet spring terminal are arranged on pedestal, wherein moving spring terminal, quiet spring terminal respectively have a leading foot.
Described base plate is rectangle, base plate respectively arranges an installation gap at two angles corresponding to the leading foot with the dynamic and static spring terminal, be used for the installation of leading foot, in order to prevent that the installation gap position is at a glue hourglass glue, at the bottom of shell correspondence position, two glue sealing benchs are set, just can effectively avoid the leakage glue phenomenon of installation gap position; Base plate and coil pin correspondence position respectively arrange a fairlead, be used for pin is installed, such structure setting greatly reduces the assembling quality of fit requirement of pedestal and base plate, and assembling speed and quality all are improved significantly, the setting of installation gap, also be convenient to the assembling of base plate and shell simultaneously.
Described shell is rectangular structure, and is simple in structure, and the assembling of base plate and shell is to adopt damascene structures, namely base plate embedded in shell, then realizes the plastic packaging of product by gluing process.
The two ends on each long limit of described base plate respectively arrange a location notch; shell base and location notch correspondence position are respectively established a guide pad; when base plate and shell assembling; just can complete easily the assembling and positioning of base plate and shell by location notch and guide pad; certain gap is arranged between described pedestal and shell; particularly the product underclearance is larger; in order to improve the external force resistance impact property of product; a protection piece respectively is set in the centre position on two long limits of base plate, can effectively increases the external force resistance impact property of product integral body.
Adopt the technical scheme that the utility model provides to produce following useful effect:
Carry out special setting by the assembly structure to base plate, shell, can reduce the quality of fit of pedestal, base plate and shell assembling, realize that coil pin, dynamic and static spring terminal lead pin assemble fast; The accurate location of base plate and shell, effectively improved efficiency of assembling and quality; Simultaneously,, by the setting of shell glue sealing bench, effectively avoid the contingent leakage glue of some glue process, guaranteed product assembly quality; By the protection piece is set at base plate, improved the external force resistance impact property of product, be not easy to carry with transportation in damage, below in conjunction with accompanying drawing, the utility model is further described.
