Connecting device applying various standard interfaces on sensor and manufacturing method of connecting device

Abstract

The invention provides a connecting device applying various standard interfaces on a sensor and a manufacturing method of the connecting device. The connecting device comprises a metal shell, a metalsubstrate, connecting square pins and an insulating plastic seat, wherein the metal shell is a protective metal shell of the sensor; the metal substrate is welded to the bottom surface of the metal shell; the metal substrate is provided with a plurality of connecting square pin mounting holes; each connecting square pin is of a folded structure; the upper end of each connecting square pin penetrates through the corresponding connecting square pin mounting hole and is inserted into the metal shell to be connected with the sensor through electronic signals; the insulating plastic seat is formedby injection molding and wraps the metal substrate and the bottom end of the metal shell; the lower ends of the connecting square pins are inserted into various standard interfaces; the metal shell, the metal substrate and the connecting square pins are independently manufactured; and the whole connecting device is combined and formed by one-time injection molding. The connecting device has the beneficial effects that the various components are independently manufactured, the total manufacturing cost is reduced, batch production is realized, one-time injection molding is realized, the production process is simplified, the overall structure is miniaturized, and the sealing performance and the protection level are improved.

Description

【Technical field】 [0001] The invention relates to the technical field of connectors, in particular to a connection device for applying various standard interfaces on a sensor and a manufacturing method thereof. 【Background technique】 [0002] At present, there are two main methods of connecting and manufacturing connectors and sensors: one is to use O-rings or glue to connect the connectors with various standard interfaces to the protective shell of the sensor; The connectors of various standard interfaces and the protective metal shell of the sensor are injection molded together. [0003] But the products manufactured by these two methods all have their limitations and product defects. The invention is a brand-new design and manufacture, which manufactures the sensor protective shell and standard connectors of various standard interfaces at one time, greatly reduces the complexity of the production process and the manufacturing cost, and improves the product protection lev...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to solve the following problems in the interface connection device currently used on the sensor: the product size is large, and the installation takes up a lot of space; the product uses O-shaped sealing ring or glue technology, which cannot meet the protection requirements above IP65, and is easy to age and Air leakage leads to sensor failure; if the product is manufactured by injection molding process, the manufacturing process of the production shell is complicated, the manufacturing cost is very high, the manufacturing efficiency is low, and the product sealing has certain limitations; and a sensor is provided. Connecting device with similar standard interface and manufacturing method thereof
