Description

Technical Field

[0001] The utility model relates to the technology in the field of fixtures, especially to a terminal block assembly fixture. Background Art

[0002] A terminal block is an electronic component used for circuit connection, also called a terminal strip, an electrical connector, etc. The terminal block consists of a socket and a plug. The socket is fixed on the electrical component through its square plate or circular plate, and in some cases, it is fixed by welding. The plug is generally connected to a cable, and the connection between the plug and the socket is achieved through a connecting nut. Since the terminal block is small in size and has high requirements, in order to ensure the accurate assembly of the terminal block, an assembly fixture is mostly used for assembly.

[0003] During the assembly process using the assembly fixture, most of the time, multiple customized tools are used to fix multiple parts of the plug. The fixing process is relatively complicated and numerous, consuming a large amount of human resources and reducing production efficiency. Moreover, due to the large number of operation steps in the fixing process and the complexity, when a problem occurs at a certain time node, the fixing of the plug will deviate, resulting in a high defective rate of the terminal block assembly. Content of the Utility Model

[0004] In view of this, aiming at the deficiencies existing in the prior art, the main purpose of the utility model is to provide a terminal block assembly fixture, which can effectively solve the problems that the existing terminal block assembly fixture needs to use multiple customized tools to fix multiple parts of the plug, the fixing process is relatively complicated and numerous, consuming a large amount of human resources and reducing production efficiency, and the defective rate of the terminal block assembly is relatively high.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A terminal block assembly fixture includes a base plate and a positioning seat; the positioning seat is arranged on the base plate, a positioning cavity adapted to the terminal block is formed on the positioning seat, and a positioning portion for positioning and cooperating with the positioning structure of the terminal block is arranged at the bottom of the positioning cavity; an openable and closable clamping mechanism is arranged on the positioning seat, the clamping mechanism has two clamping ends, and the two clamping ends are respectively located on both sides of the opening of the positioning cavity.

[0007] As a preferred solution, the clamping mechanism includes two fixing members and two clamping members. The two fixing members are arranged on the positioning seat and are respectively located on both sides of the opening of the positioning cavity. The two clamping members are respectively installed on the corresponding fixing members in a manner that they can approach or move away from the positioning cavity. Both of the two clamping members have the aforementioned clamping ends, and the two clamping members cooperate with each other to open or close the clamping mechanism.

[0008] As a preferred solution, the two fixing members are both fixedly arranged on the positioning seat through M3 screws.

[0009] As a preferred solution, an exhaust cavity extends outward from the inner wall surface of the positioning cavity. When the terminal block is inserted into the positioning cavity, the air in the positioning cavity can be smoothly discharged from the exhaust cavity.

[0010] As a preferred solution, protection cavities extend from the corners of the positioning cavity. The strength of the corners of the outer shell of the terminal block is relatively low, and it is prone to deformation or damage when stressed. The protection cavities can provide a space for the corners of the outer shell of the terminal block to prevent it from being stressed.

[0011] As a preferred solution, the substrate is made of bakelite. The bakelite substrate has high mechanical strength, good insulation, heat resistance and corrosion resistance, making the fixture more durable and having a longer service life.

[0012] Compared with the prior art, the present utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solutions:

[0013] By providing a positioning portion at the bottom of the positioning cavity that is in positioning cooperation with the positioning structure of the terminal block, and then cooperating with a clamp mechanism that can be opened and closed on the positioning seat, after the plug of the terminal block is inserted into the positioning cavity and is in positioning cooperation with the positioning portion, the clamp mechanism closes to clamp the terminal block, realizing the fixation of the terminal block in the fixture. There is no need to use multiple customized tools to fix multiple parts of the plug. The fixing process is simple, does not consume human resources, can improve production efficiency, and moreover, the simple fixing process is not prone to errors, and there will be no deviation in the fixing of the plug, effectively improving the assembly yield rate of the terminal block.

[0028] The positioning seat 20 is arranged on the substrate 10. A positioning cavity 21 adapted to the terminal block 30 is provided on the positioning seat 20. A positioning portion 22 for positioning and cooperating with the positioning structure of the terminal block 30 is arranged at the bottom of the positioning cavity 21; A separable clamping mechanism 40 is arranged on the positioning seat 20.

The two fixed parts 41 are arranged on the positioning seat 20 and on both sides of the opening of the positioning cavity 21 respectively. The two clamping pieces 42 are respectively installed on the corresponding fixed parts 41 so as to be close to or far away from the positioning cavity 21. The two clamping pieces 42 both have the aforementioned clamping ends 401, and the two clamping pieces 42 cooperate with each other to open or close the clamping mechanism 40; And the two fixed parts 41 are both fixedly arranged on the positioning seat 20 through M3 screws 43; In addition, an exhaust cavity 23 extends outward from the inner wall surface of the positioning cavity 21. When the terminal block 30 is inserted into the positioning cavity, the air in the positioning cavity 21 can be smoothly discharged from the exhaust cavity 23; And, protection cavities 24 extend from the corners of the positioning cavity 21. The strength of the corners of the shell of the terminal block 30 is relatively low, and it is easy to deform or break when stressed. The protection cavities 24 can provide a space for the corners of the shell of the terminal block 30 to prevent it from being stressed.

[0030] First, insert the plug of the terminal block 30 into the positioning cavity 21. The air in the positioning cavity 21 is discharged from the exhaust cavity 23. Then, move the two clamping members 42 closer to the positioning cavity 21 so that the clamping mechanism 40 closes to clamp the plug of the terminal block 30 for assembly. After the assembly is completed, move the two clamping members 42 away from the positioning cavity 21 so that the clamping mechanism 40 opens, and take out the assembled terminal block.

[0031] The design focus of the present utility model lies in: by providing a positioning portion at the bottom of the positioning cavity that is in positioning cooperation with the positioning structure of the terminal block, and further cooperating with a clamping mechanism that can be opened and closed on the positioning seat. After the plug of the terminal block is inserted into the positioning cavity and is in positioning cooperation with the positioning portion, the clamping mechanism closes to clamp the terminal block, realizing the fixation of the terminal block in the fixture. There is no need to use multiple customized tools to fix multiple parts of the plug. The fixing process is simple, does not consume human resources, can improve production efficiency, and moreover, the simple fixing process is not prone to errors, and there will be no deviation in the fixing of the plug, effectively improving the qualified rate of the assembly of the terminal block.
