[0012] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is intended to facilitate understanding of the present invention and does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0013] See Figures 1 to 6 , shown in the figure is a micro switch assembly tool. The micro switch assembly tool is used to assemble the wiring terminal and the lower housing together.

[0014] The micro switch assembly tooling includes: a lower end cover 1, a lower connecting plate 2, an assembly module 3, an upper connecting plate 4 and an upper end cover 5, etc.

[0015] The upper end cover 5 has an upper end cover connecting hole 51 .

[0016] The upper connecting plate 4 is below the upper end cover 5 and the upper connecting plate 4 is in surface contact with the upper end cover 5. The upper connecting plate 4 has an upper connecting plate connection hole 41 corresponding to the upper end cover connection hole 41. A connecting member 6 is provided between the upper connecting plate connection hole 41 and the upper end cover connection hole 51 to achieve a fixed connection between the upper connecting plate 4 and the upper end cover 5.

[0017] The lower end cover 1 has a lower end cover connecting hole 11.

[0018] The lower connecting plate is above the lower end cover 1 and the two are in surface contact. The lower connecting plate 2 has a lower connecting plate connection hole 21 corresponding to the lower end cover connection hole 11. A connecting member 7 is provided between the lower connecting plate connection hole 21 and the lower end cover connection hole 11 to achieve a fixed connection between the lower end cover 1 and the lower connecting plate 2.

[0019] The assembly module is located between the upper connecting plate and the lower connecting plate and includes an upper extension rod 36, a lower extension rod 31, a buffer spring 33, a cutter head 34, a connecting sleeve 32, and the like.

[0020] The upper end of the upper extension rod 36 is inserted into its corresponding positioning slot 42 on the upper connecting plate. The lower end of the upper extension rod has a square stepped hole. The small hole of the square stepped hole is wider than the upper width of the microswitch component 35's terminal block and smaller than the middle width of the microswitch component's terminal block. The large hole of the square stepped hole fits with the lower housing of the microswitch with a small clearance, providing the required installation travel between the lower housing of the microswitch and the terminal block.

[0021] In some embodiments, the upper end cover connection hole is a countersunk hole, the upper connection plate connection hole is a threaded hole, and the connection piece is a countersunk screw.

[0022] The lower end of the lower extension rod 31 is inserted into the corresponding positioning groove 22 of the lower connecting plate.

[0023] The assembly module 3 is a moving component that moves in the vertical direction to enable the upper extension rod 4 and the lower extension rod 2 to perform a mold closing movement.

[0024] The upper extension rod 4 is used for inserting the terminal block, and the terminal block is inserted into the lower housing 352 of the micro switch by pressing the shaft shoulder 351 of the terminal block, and is limited by the upper end surface of the lower housing 352.

[0025] The lower extension rod 2 has an installation hole inside for installing a cutter head 34 and a buffer spring 33. The cutter head 34 is used to split the tail of the terminal after the terminal is inserted into place to form a left-right symmetrical arc-shaped positioning support 353 to prevent position deviation after insertion and ensure insertion accuracy. The buffer spring 33 is used to prevent the terminal from being subjected to excessive force and damaging the lower shell 352 and provide supporting force.

[0026] In some embodiments, the buffer springs 33 are arranged symmetrically on the left and right to ensure that the assembly module moves more smoothly.

[0027] In some embodiments, a bottom surface of the assembly module is formed with a receiving hole for receiving the upper end portion of the buffer spring, and a top surface of the lower connecting plate is formed with a receiving hole for receiving the lower end portion of the buffer spring.

[0028] The motion block has a vertical through-slot. The vertical through-slot comprises an upper section and a lower section. The upper section accommodates the microswitch's terminal block. The lower section engages the axis of the hole in the lower extension rod. The motion block is capable of vertical displacement along the lower extension rod. The top surface of the motion block is formed with beveled surfaces on both sides.

[0029] The intermediate connecting sleeve surrounds the outer portion of the upper extension rod and the lower extension rod. The beveled surface is used to support the intermediate connecting sleeve and plays the role of mold closing guide and limit of the upper and lower extension rods.

[0030] In some embodiments, the intermediate connecting sleeve is made of a transparent material in order to visualize the assembly of the micro switch.

[0031] In some embodiments, the bottom surface of the outrigger has a downwardly extending limiting protrusion, which is used to limit the lowest position of the motion block.

[0032] In some embodiments, the lower end cover connection hole is a countersunk hole, the lower connection plate connection hole is a threaded hole, and the connection piece is a countersunk screw.

[0033] In some embodiments, a square groove is cut out of the bottom surface of the upper extension rod along the width direction, and the groove depth is the same as the large hole depth of its square step hole, which facilitates observation of the installation status of the micro switch.

[0034] In some embodiments, the number of the assembly modules is five, with one in the middle and one each in the front, back, left, and right. The micro switch assembly tool can assemble five micro switches at the same time.

[0035] The beneficial effects of the assembly tool are: (1) The device has a simple structure, convenient operation, high reliability, and is easy to install and disassemble.

[0036] (2) The device can install multiple wiring pieces in the micro switch at the same time, and can understand the installation status of the micro switch in real time, which greatly improves the installation efficiency and ensures the installation accuracy to a certain extent.

[0037] The above merely describes the embodiments of the present invention, and the description is relatively specific and detailed, but it should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art can make a number of variations and improvements without departing from the concept of the present invention, and these are all within the scope of protection of the present invention. Therefore, the scope of protection of the patent of the present invention shall be based on the appended claims.
