Introduction and Manufacturing Process of Energy Storage Connector

Release time:2023-03-20 09:04:04| Viewed：

Energy storage battery connectors can be used for wiring energy storage systems, energy storage batteries, lithium power supplies, solar energy storage systems, and various other energy storage devices.

What are the advantages of energy storage connectors

1. Improve production process

Energy storage connectors simplify the assembly process of electronic products. It also simplifies the mass production process;

2. Easy to maintain

If an electronic component fails, the faulty component can be quickly replaced when installing the energy storage connector;

3. Easy to upgrade

As technology advances, components can be updated when installing energy storage connectors, replacing the old with new and better components;

4. Improve design flexibility

The use of energy storage connectors provides engineers with greater flexibility in designing and integrating new products and building systems from components;

Interface mode between circuit boards of energy storage connectors

The interface modes and types of energy storage connector circuit boards are different, and each type has its own characteristics. The following is a brief and detailed introduction to these aspects:

1. Pin row female/pin. Pai bus and Pai pin are relatively cheap, cost-effective, and common interface methods. Application fields: low-end, large-scale intelligent products, development boards, debugging boards, and so on;

Advantages: Cheap, cost-effective, convenient, solid hard connection, strong overcurrent capacity, and conducive to wire bonding and testing;

Defects: Large volume, not easy to bend, large spacing, hundreds of pins cannot be connected (too large).

2. Some board to board connectors.Used for compact products with a higher density than row needles. Application field: It is widely used, and basic intelligent hardware products are basically in use.

Advantages: Small size, large number of stitches, capable of making 40 stitches with a length of 1 cm (within 20 stitches for the same specification).

Defect: The overall design must be fixed and expensive, and cannot be plugged in and out frequently.

3. The thickened board to board connector can be combined, disassembled, and inserted on the row of pins. Application scenarios: detection board, development board, large fixed equipment (such as main chassis cabling). Advantages: It is cheap, cost-effective and common to use with pins, and it is very convenient to connect and accurately measure. Defects: Not easy to repair, large volume, not suitable for mass production scenarios.

4. FPC connector plug/ZIF connector. Many intelligent products and machines must pull data signals out of the computer motherboard, and FPCs are small, flexible, and multi terminal in shape, making them a very good choice. Application scenarios: power circuit bending, connection of computer main board and external equipment, connection of auxiliary board and computer main board, and tight indoor space of the product. Advantage: Small and cheap.

Plug connection form of energy storage connector

1. Screw connection method of energy storage connector plug

This is a commonly used connection form for connector plugs that have larger size contacts and work in strong vibration environments. After completing the connection, a fuse or nut can be installed to prevent loosening. This connection is reliable in use, but the connection and removal speed are slow.

2. Connection method of energy storage connector plug bayonet

This is a reliable and rapid form of connection and separation. Most electrical connectors with card 121 connections have a visual display of correct connection and locking, which can be viewed from the small hole on the side of the electrical connector connecting nut.

3. Plug connection method of energy storage connector

This is a versatile form of connection. When connecting and separating the plug and socket of an electrical connector, the direction of movement is usually a reciprocating linear motion, without twisting and rotating, and only a small working space is required to complete the connection and removal. Common plug and pull connections have two types of structures: ball or pin. This type of connection has no mechanical labor saving mechanism, and once inserted incorrectly, the mechanical resistance increases significantly, which can be detected in a timely manner.

4. Connection mode of energy storage connector plug cabinet

This is an electrical connector used on some equipment that needs blind connection close to the frame, which can make the electrical equipment lighter and smaller, easier to maintain, and more reliable. This type of connection makes it impossible for the operator to feel the connection, and it is necessary to design an accurate positioning device to avoid forcibly connecting the incorrectly inserted connector plugs together, making incorrect insertion impossible. Connector plugs usually use floating or elastic contact design structures to ensure their correct connection.

Characteristics of energy storage connector:

Special connector for energy storage

1. The energy storage battery connector has the characteristics of high temperature resistance, voltage resistance, chemical corrosion resistance, and high cleanliness.

2. Featuring high reliability, accurate positioning, low noise and vibration, strong impact resistance, convenient installation, and high reliability, it is widely used in various power systems with high requirements.

3. Fine workmanship, high strength, stable quality, good protection, good ventilation, high temperature resistance, safety and reliability, voltage resistance, and other characteristics can greatly shorten the replacement and fixation time, and is easy to disassemble.

Brief description of manufacturing process of energy storage connector

Many people believe that there are too many types of energy storage connectors, and the manufacturing process should be different. In fact, the manufacturing process of energy storage connectors is basically the same, which can be divided into four manufacturing processes: stamping, electroplating, injection molding, and assembly.

1. Stamping

Stamping is a process of stamping electronic energy storage connectors (pins) from thin metal strips using a large high-speed stamping machine. One end of a large roll of metal tape is fed into the front end of the press, and the other end is wound through the hydraulic workbench of the press into a winding pulley. The winding pulley pulls out the metal tape and rolls it up to press out the finished terminal.

2. Electroplating

After stamping the energy storage connector pins, they should be sent to the electroplating stage. During the electroplating phase, the electronic contact surface of the energy storage connector will be plated with various metal coatings, including nickel, tin, and semi gold, to prevent oxidation and enhance electrical conductivity. During the process of feeding stamped pins into electroplating equipment, pins can also be twisted, broken, or deformed. These quality defects can easily be detected through the above techniques.

3. Injection molding

Injection molding refers to the rapid cooling and molding of the plastic box seat of an electronic energy storage connector by injecting molten plastic into a metal tire film.

Also pay attention to detecting "Short Shorts" when the molten plastic is not completely filled with the film, which is a typical defect that needs to be detected during the injection molding stage. Other defects include full or partial plugging of the sockets (these sockets must be kept clean and smooth in order to properly connect to the pins during final assembly).

4. Assembly

The final stage of manufacturing electronic energy storage connectors is the assembly of the finished product. There are two ways to connect and assemble electroplating pins and injection box seats: the first is to insert them separately, that is, one pin at a time;

The second type is a combined plug, which refers to connecting multiple pins to the box socket simultaneously. Regardless of the connection method used for assembly, ensure that all pins are not missing and must be positioned correctly.
