[0002] In the field of electronic manufacturing and maintenance, the installation of wire harness connector pins is a common and important task. The traditional method of installing pins usually relies on manual single-pin operation, that is, workers need to insert the pins into the corresponding holes of the wire harness connector one by one. This operation method is not only inefficient, but also prone to inaccurate pin installation positions or pin damage due to human factors, thus affecting the quality and performance of the product.

[0003] As electronic products become increasingly complex and sophisticated, the number of pins in wiring harness connectors continues to increase, placing higher demands on the accuracy and efficiency of pin installation. Therefore, developing a tooling device that can efficiently and accurately complete the installation of multiple pins has become an urgent problem to be solved in the current electronic manufacturing and maintenance fields.

[0004] At present, although there are some auxiliary tools for pin installation on the market, most of these tools can only realize the installation of a single pin and cannot meet the needs of installing multiple pins at the same time. In addition, these tools often require manual assistance during operation and cannot be fully automated, so their operating efficiency is still greatly limited. Therefore, the development of a handheld pin installation tool that can replace the original single-pin operation method and realize the simultaneous installation of multiple pins is of great significance for improving production efficiency, reducing labor costs, and improving product quality in the field of electronic manufacturing and maintenance.

[0020] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0021] like Figure 1-4 As shown, the handheld pin installation tool of this embodiment includes a mounting plate 1 and a limiting plate 2. The mounting plate 1 is provided with a pre-installation area 3 for installing pins, and the limiting plate 2 is provided with an ejector pin 4 corresponding to the position of the pre-installation area 3. The distance between the mounting plate 1 and the limiting plate 2 is adjustable. When the distance between the mounting plate 1 and the limiting plate 2 is reduced, the ejector pin 4 can eject the pin installed in the pre-installation area 3, and finally realize the transfer of the pin from the mounting tool to the terminal block. Compared with the traditional single-pin insertion method, it can transfer the pins in batches, effectively improving the working efficiency.

[0022] A plurality of sockets 5 are provided in the pre-installation area 3, one end of the ejector pin 4 is connected to the limiting plate 2, and the other end extends into the socket 5. The ejector pin 4 is located at the bottom of the socket 5 in the initial working state, and can play a limiting role at the bottom when installing the pin, thereby preventing the pin from being positioned too low during installation and affecting the alignment and plugging.

[0023] The number and position of the ejector pins 4 correspond to the socket 5. A positioning block 6 is provided at one end of the ejector pin 4 connected to the limit plate 2. A storage chamber 7 corresponding to the position of the positioning block 6 is provided on the limit plate 2. A through hole 8 for penetrating the ejector pin 4 is provided at the end of the storage chamber 7. The storage chamber 7 is an independent chamber, and the number and position are the same as those of the ejector pin 4, which facilitates the separate disassembly and assembly of the ejector pin and simplifies the maintenance operation.

[0024] There are two pre-installation areas 3 and they are symmetrically distributed with the center line of the mounting plate 1 as the axis. The limiting plate 2 is provided with ejector pins 4 corresponding to each pre-installation area 3. The design of the two pre-installation areas 3 can simultaneously complete the pin packaging operation of the two terminal blocks, thereby improving the operation efficiency.

[0025] A handle 9 for pulling the mounting plate 1 for displacement is provided on the outer side of the limiting plate 2, and guide columns 10 connected to the mounting plate 1 are provided at both ends of the handle 9, and a return spring 11 located between the mounting plate 1 and the limiting plate 2 is provided on the outside of one end of the guide column 10 connected to the mounting plate 1, and a guide hole 12 corresponding to the position of the guide column 10 is provided on the limiting plate 2. Through the design of the guide hole 12, guiding operation can be performed in the process of pulling the mounting plate 1 to move, ensuring that the mounting plate will not deflect during the movement to avoid damage to the pins, and a limiting boss is provided at the joint between the guide column 10 and the outer wall of the limiting plate 2, and the function of the lower limiting boss is to fix the limiting plate 2 to prevent the limiting plate 2 from moving backward.

[0026] A locating pin 13 is provided in the middle of the limit plate 2, one end of the locating pin 13 is fixedly connected to the limit plate 2, and the other end extends to the inner side of the mounting plate 1. A avoiding hole 14 corresponding to the position of the locating pin 13 is provided in the middle of the mounting plate 1. The locating pin 13 extending to one end of the inner side of the mounting plate 1 is provided with a locating sleeve 16 which is clamped with the external mold. After the locating pin 13 abuts against the external mold, the locating sleeve 16 can be clamped with the external mold, so as to fix the limit plate 2.

[0027] The locating pin 13 is connected to the limit plate 2. A tightening plate 15 connected to the locating pin 13 is provided on the outer side of the limit plate 2. Both ends of the tightening plate 15 extend to the outer side of the ejector pin 4 to press the ejector pin 4. When the ejector pin 4 ejects the pin, the outer side of the ejector pin 4 is tightened to prevent the ejector pin 4 from separating from the limit plate 2.

[0028] The working principle / assembly process of this solution: install the pin from the socket 5 in the handheld tooling, and then connect the movable end of the pin with the replaced terminal. Before connecting, the terminal that needs to be replaced with the pin needs to be fixed with the positioning tooling to avoid misalignment during the plug-in process. In the process of transferring the pin, first align the handheld tooling with the installed pin and the positioning tooling with the terminal fixed, and complete the alignment work by plugging the sleeve and the positioning tooling. Then use the handle 9 to pull the mounting plate 1 backwards, and the mounting plate 1 slides along the guide column 10, while compressing the reset spring 11. At this time, the limit plate 2 is fixed, and the ejector pin 4 will push the pin out in the socket 5 as the mounting plate 1 slides, and the ejected pin will enter the terminal, and finally complete the transfer of the pin.
