Product structure design and process adaptation of terminals blocks

Terminal blocks are a kind of appurtenant product used to realize the electrical connection, which is divided into the order of connectors in the assiduity. With the adding degree of artificial robotization and the stricter and more precise conditions of artificial control, the quantum of terminals blocks is gradationally adding. With the development of electronics assiduity, the use of terminal blocks is adding, and there are more and more types. In addition to PCB board outstations, the most extensively used bones are tackle outstations, nut outstations, spring outstations, and so on. What are the product structure design and process adaptation of terminals blocks? Then are some answers.

Product structure design

The design of the product structure of terminals blocks is also veritably important, which is entirely a matter of experience, and there's no roadway to take. In this regard, each series has its characteristics, similar to screw forestallment, spliced products are twisted in the front and back, long number distortion, etc., loss distortion caused by uneven wall consistence, etc.

The forestallment of terminal blocks screws substantially includes the following types three caricature forestallment, circle forestallment, neck forestallment, and stamping forestallment. The consummation of the below structure is grounded on the premise that the plastic material is PA66. Then we need to explain the forestallment of the neck opening. Take the terminal blocks to screw as M3 as an illustration, the factual external periphery of the M3 screw is φ2.90 mm, so the size of the neck of the shell should be designed to be φ2.5 ～ φ2.6, the consistency of the neck of the shell should be 0.4 to 0.5 mm, and there should be a polished rod under the head of the screw that's lower than the neck of the shell, to ensure that the outstations block screws can be Squinch it into the thread easily.

Process Adaptation

1. The main reason for the distortion problem of long integers in the combination of spliced products is also due to the unreasonable structure, which leads to the unstable force of the two spliced falcons in the front, and back, over, down, left, and right. It's shown that the force of the spliced falcon should be considered in the structural design of the outstation blocks. and distortion direction.

2. The problem of precluding the screws of terminals blocks from falling off. In this regard, it's recommended to use the neck opening as much as possible, because it avoids the troubles caused by the forbearance delicacy of the screw rod and the circle opening compared with the circle opening forestallment, and the structure is dependable.

3. The swab spray test of terminals blocks screws and threaded sword corridor after electroplating is grounded on the standard of thread electroplating (the coating is limited, but the consistency of the thread corresponding to the coating needs to be further determined), to break this problem in terminals blocks When the electroplating process is normal, there are two styles, opting the correct sealing agent and using the plating subcaste to electroplate multiple times. The cost of electroplating in multiple layers is high, so it's recommended to use the first system, and the key to this system is the exploration of the formula of the sealing agent.

4. The problem of the draw-in force of terminals blocks, which involves a lot of content, is related to accouterments, electroplating, structure, and the applied assiduity. It's an important mechanical performance demand in the connector assiduity. This is especially true for type terminals blocks, where the choice of material is limited by electrical conductivity (current) and contact resistance, and temperature rise in terms of insertion force. It'll not be explained in detail then. Electroplating is substantially affected by the type of coating and whether it's-plated.
