Description

Technical Field

[0001] This invention relates to the field of cable manufacturing technology, and in particular to an apparatus for assembling micro rectangular connectors. Background Technology

[0002] The demands for high performance, miniaturization, and lightweight electronic equipment are driving the development of cable assemblies towards integration, miniaturization, and high reliability. Among various cable assemblies, micro rectangular connector cable assemblies meet the trend of equipment miniaturization and are widely used in military fields such as aviation, aerospace, electronics, weaponry, communications, and shipbuilding.

[0003] The assembly process for micro-rectangular cable assemblies, represented by the J30J series, is demanding and involves numerous operational challenges. After cable crimping, users need to insert the contacts into the connector housing and perform potting operations.

[0004] There are many types of micro rectangular connectors in the existing technology. The contact arrangements of various micro rectangular connectors are different. However, traditional assembly tooling is only designed for a single type of micro rectangular connector and cannot be applied to multiple types of micro rectangular connectors. As a result, each type of connector has a separately designed fixture, which increases production costs. Furthermore, the variety of fixtures is difficult to manage and operators are easily confused, which reduces work quality and makes the assembly process more complicated. Summary of the Invention

[0005] Based on the above analysis, the present invention aims to provide an apparatus for assembling micro rectangular connectors, so as to solve the problems of existing assembly tooling being unsuitable for various types of micro rectangular connectors, high production costs, and complex operation.

[0006] The objective of this invention is mainly achieved through the following technical solutions:

[0007] An apparatus for assembling micro rectangular connectors includes an assembly plate and a positioning sleeve. The assembly plate includes a clamping plate and a base plate stacked sequentially, and the positioning sleeve passes through the clamping plate and is inserted into the base plate.

[0008] Furthermore, the base plate has a groove with an opening at the top, but the groove does not penetrate the base plate.

[0009] Furthermore, the clamp plate has through holes, through which the positioning sleeve can pass.

[0010] Furthermore, the groove on the base plate is opposite to the through hole on the clamping plate.

[0011] Furthermore, the assembly plate also includes a first adjustment component, which is capable of adjusting the distance between the clamping plate and the base plate.

[0012] Furthermore, the first adjustment component includes a first lead screw, and the clamping plate has a threaded hole that passes through the clamping plate; the first lead screw passes through the threaded hole and is rotatably connected to the base plate.

[0013] Furthermore, the first adjustment component also includes a first slide rail, one end of which is connected to a clamping plate.

[0014] Furthermore, the first slide rail includes a first support plate and a second support plate that are vertically connected, with one end of the first support plate connected to a clamping plate and the other end connected to the second support plate.

[0015] Furthermore, the second support plate has square through holes on its body.

[0016] Furthermore, the first adjustment component also includes a locking block, which is disposed between the base plate and the second support plate; one end of the locking block is vertically connected to the base plate, and the other end is movably inserted into the square through hole of the second support plate.

[0017] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0018] (1) The device for assembling micro rectangular connectors of the present invention has a clamp plate that can be divided into multiple regions. Each region has a circular through hole that penetrates the plate for inserting a positioning sleeve. The arrangement of the through holes in different regions is different, so that the arrangement of the positioning sleeve in each region corresponds to the arrangement of a micro rectangular connector contact body. This enables the assembly of different types of micro rectangular connectors and improves the ease of operation.

[0019] (2) The device for assembling micro rectangular connectors of the present invention has a first adjustment component on the assembly plate. The first adjustment component includes a first lead screw and a threaded hole through the plate body on the clamping plate. The first lead screw passes through the threaded hole and is rotatably connected to the base plate. Tightening the first lead screw can drive the clamping plate to move vertically relative to the base plate, thereby changing the length of the contact body extending into the positioning sleeve, thereby realizing the adjustment of the contact body connection length to adapt to micro rectangular connectors with different length requirements and reduce production costs.

[0020] (3) The device for assembling micro rectangular connectors of the present invention further includes a first slide rail and a locking block. The first slide rail includes a first support plate and a second support plate connected vertically. The first support plate is connected to a clamping plate. The plate body of the second support plate is provided with a square through hole as a slide rail for the locking block. One end of the slider is connected to the base plate, and the other end is movably inserted into the through hole of the second support plate, so that the clamping plate can maintain the vertical direction when it moves relative to the base plate, and avoid the clamping plate from shifting during the movement.

[0021] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages may become apparent from the specification or be learned by practicing the invention.

Detailed Implementation

[0032] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and, together with the embodiments of the present invention, serve to illustrate the principles of the present invention.

[0033] Example 1

[0034] This embodiment discloses an apparatus for assembling micro rectangular connectors, such as... Figure 1 As shown, it includes an assembly plate 1 and a positioning sleeve 2. The assembly plate 1 is used to assemble the micro rectangular connector and includes a clamping plate 11 and a base plate 12 stacked vertically from top to bottom. The positioning sleeve 2 passes through the clamping plate 11 and is inserted into the base plate 12.

[0035] The positioning sleeve 2 is a cylindrical body with a through hole. The contact in the micro rectangular connector is a twisted pin. The twisted pin can be inserted into the through hole of the positioning sleeve 2 for positioning. In order to prevent the twisted pin from shaking in the positioning sleeve 2, the twisted pin can be made to fit against the end face of the through hole of the positioning sleeve 2. Multiple positioning sleeves 2 can be set and arranged according to the arrangement of the contact of different types of micro rectangular connectors, so as to realize the assembly and fixation of various types of micro rectangular connectors.

[0036] It should be noted that in the micro rectangular connector, the contact body is glued to the insulator. The insulator has through holes to insert the contact body and arrange it in a certain way, which determines the type of micro rectangular connector to be assembled. When using it, the operator first puts the insulator through the through holes on the outside of the positioning sleeve 2, then inserts the contact body into the through holes of the positioning sleeve 2 and protrudes from the top of the positioning sleeve 2 and the insulator. After crimping the wire to the top of the contact body, the insulator and the contact body are glued from above the insulator by potting glue, thus completing the assembly of the micro rectangular connector.

[0037] The clamping plate 11 is divided into multiple regions, and each region has a circular through hole that penetrates the plate to insert the positioning sleeve 2. Thus, the distribution of the through holes corresponds to the positioning sleeve 2. In order to realize the assembly of different types of micro rectangular connectors, the arrangement of the through holes in different regions is different, so that the arrangement of the positioning sleeve 2 in each region corresponds to the arrangement of the micro rectangular connector contact body. Furthermore, in order to prevent the positioning sleeve 2 from shifting within the clamping plate 11, the positioning sleeve 2 can be made to fit against the end face of the through hole.

[0038] The base plate 12 is a square plate, and a circular groove with an opening at the top is provided on the plate body. The base plate 12 is used to limit the positioning sleeve 2 that passes through the clamping plate 11 in the vertical direction. Therefore, the groove does not penetrate the plate body of the base plate 12. In order to prevent the positioning sleeve 2 from shifting in the groove, the positioning sleeve 2 can be made to fit against the end face of the groove.

[0039] To facilitate the vertical support of the positioning sleeve 2, the grooves on the base plate 12 are distributed in the same way as the positioning sleeve 2 and communicate with the through holes on the clamping plate 11.

[0040] See Figure 2 The clamping plate 11 and the base plate 12 can be moved relative to each other through the first adjusting component 13 to adjust the distance between them. The first adjusting component 13 includes a first lead screw 131, a first slide rail 132 and a locking block 133. Both the clamping plate 11 and the base plate 12 are square plates. The clamping plate 11 is provided with a threaded hole that passes through the plate body to install the first lead screw 131. After the first lead screw 131 passes through the threaded hole, it is rotatably connected to the base plate 12. Tightening the first lead screw 131 can drive the clamping plate 11 to move vertically relative to the base plate 12, so that the length of the contact body extending into the positioning sleeve 2 changes, thereby realizing the adjustment of the contact body connection length to adapt to micro rectangular connectors with different length requirements.

[0041] The first lead screw 131 is located at the first end of the clamping plate 11 and is used to adjust the distance between the clamping plate 11 and the base plate 12; the first slide rail 132 is located at the second end of the clamping plate 11 and is used to prevent the clamping plate 11 from deviating from the vertical direction when moving relative to the base plate 12; specifically, see Figure 3 The first slide rail 132 includes a first support plate 1321 and a second support plate 1322 arranged vertically. The first support plate 1321 is arranged vertically at the second end of the clamping plate 11, so that the second support plate 1322 does not contact the clamping plate 11 or the base plate 12. The plate body of the second support plate 1322 is provided with a square through hole as a slide rail for the locking block 133. The locking block 133 is a square column, one end of which is vertically connected to the base plate 12, and the other end is inserted into the through hole and moves vertically against the end face of the through hole. This ensures that the clamping plate 11 can move in a direction perpendicular to the base plate 12 without deviation, further improving the stability of the device.

[0042] Furthermore, to prevent the contact from shifting within the positioning sleeve 2 and affecting the connector quality, the contact can be made to fit against the inner cavity end face of the positioning sleeve 2.

[0043] To prevent the positioning sleeve 2 from shifting during the potting process, which would cause the contact inside the positioning sleeve 2 to deviate from its predetermined position and affect the quality of the connector, a soft anti-slip layer can be evenly applied inside the positioning sleeve 2 to increase the frictional resistance between the contact and the positioning sleeve 2 and improve the relative stability between the contact and the positioning sleeve 2.

[0044] Example 2

[0045] This embodiment is another design based on embodiment 1. Compared with embodiment 1, embodiment 2 adds an adjustment frame 3 to adjust the assembly plate 1 according to actual needs, which is more flexible and saves operating space.

[0046] See Figure 4 The adjustment frame 3 includes a base 31, a first support plate 32, and a second adjustment component 33. The first support plate 32 and the second adjustment component 33 are both vertically mounted on the base 31, and the second adjustment component 33 is connected to the first support plate 32.

[0047] Furthermore, the base 31 is preferably a square plate, which facilitates the vertical placement of the adjustment frame 3.

[0048] The first support plate 32 is vertically disposed at both ends of the base 31, including a main body 321 and a slot 322. The main body 321 is vertically disposed on the base 31. The end face of the main body 321 facing the operator is provided with a square groove as the second slide rail 3211 of the second adjustment component 33. The slot 322 is used to engage the assembly plate 1 from both ends. It is vertically disposed on the surface of the main body 321 that is perpendicular to the surface where the second slide rail 3211 is located. It includes a third support plate 3221 and a fourth support plate 3222 distributed vertically from top to bottom. The two support plates are spaced apart to form a groove to engage the assembly plate 1, thereby limiting the assembly plate 1 in the vertical direction and allowing the assembly plate 1 to move along the slot 322.

[0049] Furthermore, the clamping plate 11 in the assembly plate 1 protrudes from both ends of the base plate 12, so that both ends of the clamping plate 11 can be inserted into the slot 322 for engagement. In order to enable the clamping plate 11 to move stably in the slot 322, the clamping plate 11 can be made to fit against the end face of the slot 322. The movement of the clamping plate 11 in the slot 322 drives the base plate 12 to move synchronously.

[0050] Furthermore, the third support plate 3221 has a threaded hole that passes through the plate body, so that the threaded hole communicates with the groove formed by the third support plate 3221 and the fourth support plate 3222. The first adjusting screw 323 is installed in the threaded hole. Tightening the first adjusting screw 323 can press and fix the clamping plate 11 in the groove, thereby realizing the extension and fixation of the clamping plate 11 in the slot 322.

[0051] Furthermore, the main body 321 is provided with multiple vertically distributed slots 322 to install multiple assembly plates 1. Multiple areas can be set on the same assembly plate 1, and the arrangement of the positioning sleeves 2 in each area is different to correspond to different micro rectangular connectors. For ease of operation, the positioning sleeves 2 on the same assembly plate 1 can correspond to the same type but different sizes of micro rectangular connectors, and different assembly plates 1 correspond to different types of micro rectangular connectors.

[0052] It should be noted that when using the adjustment frame 3, the operator can pull out the assembly plate 1 containing the positioning sleeve 2 of the micro rectangular connector to be assembled from the first support plate 32 according to actual needs, and then tighten the first adjusting screw 323 on the slot 322 to fix the assembly plate 1 in the slot 322. Other unnecessary assembly plates 1 are retracted into the first support plate 32. After the assembly is completed on the assembly plate 1, the first adjusting screw 323 can be tightened to release the fixation and retract the assembly plate 1 into the first support plate 32. This makes the operation more flexible, and the vertical arrangement of the assembly plates 1 helps to save space and facilitates management.

[0053] See Figure 5 The second adjusting component 33 is used to reinforce and fix the assembly plate 1 extending from the first support plate 32, preventing the assembly plate 1 from detaching from the slot 322 and from shaking during assembly, which would affect the quality of the finished product. The second adjusting component 33 includes a fixed column 331, a spring 332, a moving block 333, and an intermediate rod 334. The fixed column 331 is a circular column, vertically mounted on the base 31, and the spring 332 is sleeved on the fixed column 331. The moving block 333 is a circular column with a through hole, and the moving block 333 is movably sleeved on the fixed column 332 through the through hole. The column 331 is located on the upper end of the spring 332, so that the spring 332 can drive the moving block 333 to move vertically through the elastic force. In order for the moving block 333 to move stably along the fixed column 331, the fixed column 331 can be made to fit the end face of the through hole of the moving block 333. The intermediate rod 334 is a square rod, one end of which is connected to the moving block 333, and the other end is fitted into the second slide rail 3211 to radially limit the moving block 333, so as to prevent the moving block 333 from radially deviating during the vertical movement along the fixed column 331.

[0054] To prevent the spring force of the spring 332 from ejecting the moving block 333 from the top of the fixed post 331, one end of the spring 332 can be fixed to the base 31 or the bottom of the fixed post 331, and the other end can be connected to the moving block 333.

[0055] Further, see Figure 6 The clamping plate 11 has a limiting groove 111 with an opening at the bottom edge of the plate body. The end of the limiting groove 111 facing the fixing post 331 is open to facilitate insertion. The side wall of the moving block 333 has a limiting block 3331. The limiting block 3331 can be pushed into the limiting groove 111 from the bottom to engage, thereby supporting the assembly plate 1 that extends out of the first support plate 32 and enhancing the stability of the assembly plate 1.

[0056] To further enhance the stability of the assembly plate 1, the side wall of the movable block 333 is provided with a threaded hole communicating with the through hole for installing the second adjusting screw 335. Tightening the second adjusting screw 335 can cause it to press against the fixed column 331 inside the movable block 333, thereby fixing the movable block 333 to the fixed column 331.

[0057] It should be noted that when the operator uses the second adjustment component 33, first, the required assembly plate 1 is pulled out and fixed in the slot 322. Then, the second adjustment screw 335 is turned to release the moving block 333 from the fixed post 331. The spring 332, which is in a compressed state, will spring the moving block 333 upward to the extended assembly plate 1. Relying on the elastic force of the spring 332, the limiting block 3331 on the moving block 333 pushes into the limiting groove 111 on the assembly plate 1 to engage. Thus, the assembly plate 1 is supported by the compression elastic force of the spring 332. If it is necessary to further enhance the stability of the assembly plate 1, the moving block 333 can be pressed and fixed to the fixed post 331 by turning the second screw. The setting of the second adjustment component 33 enhances the stability of the assembly plate 1 and makes the operation simpler through the elastic force of the spring 332.

[0058] Example 3

[0059] This embodiment is an alternative design for the base plate 12 in Embodiments 1 and 2.

[0060] The base plate 12 is used to adjust the length of the contact body of the assembly of a single micro rectangular connector. Therefore, multiple base plates 12 can be set at the bottom end of the clamping plate 11, so that the base plate 12 can be adjusted for the vertical position of the positioning sleeve in a single area, which is beneficial to improve the flexibility of the device and expand the application range.

[0061] Specifically, see Figure 7The base plate 12 includes a telescopic rod 121, a movable frame 122, a second support plate 123, and a second lead screw 124. The movable frame 122 is a square frame with an open top, including a third support plate at the bottom and four side walls surrounding the frame. The side walls are vertically connected to the support plate. The third support plate has grooves on its body to receive the positioning sleeve, so the grooves do not penetrate the plate. Furthermore, the arrangement of the grooves on the third support plate corresponds to the arrangement of the contacts in a single micro-rectangular connector.

[0062] Furthermore, the second support plate 123 is vertically mounted on the side wall of the movable frame 122 facing the operator. The plate body of the second support plate 123 is provided with a threaded hole that passes through the plate body to install the second lead screw 124. After the second lead screw 124 passes through the threaded hole, it is rotatably connected to the clamping plate 11. Tightening the second lead screw 124 can drive the movable frame 122 to move relative to the clamping plate 11.

[0063] To ensure that the movable frame 122 moves stably and vertically relative to the clamping plate 11, telescopic rods 121 are provided on the side walls at both ends of the movable frame 122. The side wall where the telescopic rod 121 is located is perpendicular to the side wall where the second support plate 123 is located. One end is vertically connected to the clamping plate 11, and the other end is connected to the movable frame 122. The telescopic rod 121 is a sleeve structure, including an outer tube and an inner rod. The outer tube is a column with a square through hole, and the inner rod is also a square rod, so that the inner rod can fit against the end face of the through hole of the outer tube for stable movement.

[0064] Furthermore, the upper end of the inner rod is connected to the clamping plate 11, and the lower end of the outer tube is connected to the moving frame 122, thereby preventing the moving frame 122 from shifting during the movement of the moving frame 122 driven by the second lead screw 124.

[0065] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
