Shell rigid protection and contact pin switching printed board networking method for CSB bus cable network

Abstract

The invention relates to a networking method for a cable network, in particular to a shell rigid protection and contact pin switching printed board networking method for a CSB bus cable network, and belongs to the technical field of cable networking. Printed board through hole welding is conducted in the mode that a contact pin is bent by 90 degrees, the contact pin replaces a stranded conductor and is bent and welded, and conductor welding reliability is improved. Rigid protection to an inner welding point is achieved. Two half metal shell bodies are buckled together and then are welded, external force is effectively prevented from being transferred to the inner welding point, and the possibility that the welding point is cracked under the action of the external force is avoided. The shell rigid protection and contact pin switching printed board networking method has the good anti-vibration and anti-impact performance. Due to the facts that rigid shell body buckling and welding are conducted, and the shell bodies are filled with silica gel, the whole anti-vibration and anti-impact performance of products is greatly improved, the spectrum impact can reach 1600g, and the random vibration total root-mean-square acceleration magnitude can reach 35.4g.

Description

technical field [0001] The invention relates to a method for networking a cable network, in particular to a method for rigidly protecting a housing of a CSB bus cable network and connecting pins to a printed board, and belongs to the technical field of cable networking. Background technique [0002] CSB bus is the abbreviation of C-Serial Bus, its structure is as follows figure 1 Shown; its full name is the serial multiplex data bus. CSB bus is a low-speed multi-wire synchronous bus. One bus can provide the access capability of 31 terminal devices. The bus adopts TTL level standard and single-ended transmission. The bus cable network consists of electrical connectors, shielded cables, and distribution modules. It is composed of auxiliary materials and has a redundant design. Bus transmission of data is an inevitable trend in the development of integrated electronic systems. The CSB bus cable network adopts a bus-type connection relationship, which reduces the number of tel...

Problems solved by technology

[0005] The purpose of the present invention is to provide a shell rigid protection and pin transfer printing for CSB bus cable network in order to overcome the deficiencies that the traditional multi-strand wires are easy to break when bent and welded and the flexible shielding net sleeve cannot protect the solder joints from external forces. The method of board making and networking can prevent external force from being transmitted to the internal solder joints, and the bending of pins can replace the bending of multi-strand wires, which can enhance the mechanical environmental performance of the product and improve the reliability of use; this method protects the rigidity of the shell and transfers the pins The printed board method realizes the continuous networking of CSB bus branching modules, connectors and shielded cables, thus solving the problem of multi-strand wires being bent and directly welded and easily broken; the shell is rigidly protected to prevent external forces from being transmitted to the internal solder joints and protect the solder joints No force; improve the product's anti-vibration and shock performance
