Description

Technical Field

[0001] This invention relates to the field of cable manufacturing technology, and in particular to an assembly method for a micro rectangular connector. 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 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] In view of the above analysis, the present invention aims to provide an assembly method for a micro rectangular connector, so as to solve the problems of complex operation, difficulty in adjustment and high production cost in the assembly of micro rectangular connectors in the prior art.

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

[0007] An assembly method for a micro rectangular connector, comprising assembling the connector using a device for assembling micro rectangular connectors;

[0008] The assembly method includes the following steps:

[0009] Step S1: Adjust the assembly plate; pull the assembly plate out of the slot of the first support plate and fix it in place;

[0010] Step S2: Assemble the micro rectangular connector; first, movably mount the insulator of the micro rectangular connector onto the positioning sleeve, and then insert the contact of the micro rectangular connector into the positioning sleeve;

[0011] Step S3: Unload the micro rectangular connector; detach the contacts and insulators of the micro rectangular connector, which are glued together, from the positioning sleeve.

[0012] Furthermore, step S1 includes the following steps:

[0013] Step S11: Select assembly board; Select the assembly board according to the type of micro rectangular connector to be assembled;

[0014] Step S12: Fix the assembly plate; fix the assembly plate in the slot;

[0015] Step S13: Support the assembly plate; support the assembly plate by moving blocks.

[0016] Furthermore, in step S12, the assembly plate is pressed and fixed using the first adjusting screw in the threaded hole of the third support plate.

[0017] Furthermore, in step S13, the second adjusting screw inside the threaded hole of the moving block is turned to release the relative fixation between the moving block and the fixed column.

[0018] Furthermore, in step S13, after the movable block is released from the fixed column, the spring compressed between the movable block and the base will spring the movable block upward and make the movable block press against the assembly plate for support.

[0019] Furthermore, in step S13, when the moving block presses against the assembly plate, the limiting block on the moving block presses into the limiting groove on the assembly plate to engage.

[0020] Furthermore, step S2 includes:

[0021] Step S21: Insert the micro rectangular connector contact body; insert the micro rectangular connector into the positioning sleeve;

[0022] Step S22: Adjust the micro rectangular connector contact body; adjust the distance between the clamping plate and the base plate.

[0023] Furthermore, in step S21, the insulator of the micro rectangular connector is first fitted onto the positioning sleeve, and then the contact of the micro rectangular connector is inserted into the positioning sleeve.

[0024] Furthermore, in step S22, during the process of moving the clamping plate relative to the base plate by turning the first lead screw, the locking block connected to the clamping plate moves synchronously along the first slide rail under the action of the clamping plate.

[0025] Furthermore, the device for assembling the micro rectangular connector includes an assembly plate and a positioning sleeve, the positioning sleeve being vertically disposed on the assembly plate.

[0026] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0027] (1) The assembly method of the micro rectangular connector of the present invention selects a suitable assembly plate according to the type of micro rectangular connector to be assembled. Because the contact arrangement of different types of micro rectangular connectors is different, the arrangement of the through holes of the clamping plate and the groove of the base plate in different assembly plates is different, which can realize the assembly of different types of micro rectangular connectors and improve the convenience of operation.

[0028] (2) The assembly method of the micro rectangular connector of the present invention is that turning the first 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.

[0029] (3) In the assembly method of the micro rectangular connector of the present invention, during the process of turning the first screw to move the clamping plate relative to the base plate, the clamping block connected to the clamping plate moves synchronously along the first slide rail under the drive of the clamping plate, thereby ensuring that the clamping plate can move in the vertical direction of the base plate and improving the stability of the device.

[0030] 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. The objectives and other advantages of this invention can be realized and obtained from the content specifically pointed out in the text and accompanying drawings. Attached Figure Description

Detailed Implementation

[0041] 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.

[0042] Example 1

[0043] This embodiment discloses an assembly method for a micro rectangular connector, which uses a device for assembling micro rectangular connectors to achieve the assembly and fixation of contact bodies of different types of micro rectangular connectors.

[0044] See Figure 1 The device for assembling micro rectangular connectors includes an assembly plate 1 and a positioning sleeve 2. The assembly plate 1 is used to assemble micro rectangular connectors and includes a clamping plate 11 and a base plate 12 that are stacked vertically from top to bottom. The positioning sleeve 2 passes through the clamping plate 11 and is inserted into the base plate 12.

[0045] The positioning sleeve 2 is a cylindrical body with a through hole. The contact in the micro rectangular connector is a twisted pin, which 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. In order to prevent the contact from shifting in the positioning sleeve 2 and affecting the quality of the connector, the contact can be made to fit against the end face of the inner cavity of the positioning sleeve 2. In addition, a soft anti-slip layer can be evenly coated 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.

[0046] In one specific embodiment of the present invention, see [reference needed]. Figure 7 Assembly using a device for assembling micro rectangular connectors includes the following steps:

[0047] Step S1: Adjust assembly plate 1;

[0048] Step S2: Assemble the micro rectangular connector;

[0049] Step S3: Unload the micro rectangular connector;

[0050] Step S4: Replace assembly plate 1;

[0051] Furthermore, the adjustment of the assembly plate in step S1 mainly includes the following steps:

[0052] Step S11: Select assembly plate 1; Select the appropriate assembly plate 1 according to the type of micro rectangular connector to be assembled, because the contact arrangement of different types of micro rectangular connectors is different, thus the arrangement of the through holes of the clamping plate 11 and the grooves of the base plate 12 in different assembly plates 1 is different.

[0053] In one specific embodiment of the present invention, in step S11, the plate body of the clamping plate 11 is divided into multiple regions, and each region is provided with a through hole penetrating the plate body to insert the contact body and arrange it in a certain way, thereby determining the type of micro rectangular connector to be assembled; the main plate body 321 is provided with multiple vertically distributed slots 322 to install multiple assembly plates 1, and multiple regions are provided on the same assembly plate 1. The arrangement of the positioning sleeves 2 in each region is different to correspond to different micro rectangular connectors. In order to facilitate 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.

[0054] Step S12: Fix assembly plate 1;

[0055] Step S121: Pull out the assembly plate 1; Pull out the selected assembly plate 1 from the slot 322 of the first support plate 32, so that the area on the assembly plate 1 corresponding to the arrangement of the micro rectangular connector contact body to be assembled protrudes from the main body 321 to facilitate the assembly operation.

[0056] Step S122: Initially fix the assembly plate 1; Tighten the first adjusting screw 323 in the threaded hole of the third support plate 3221 on the slot 322, so that the first adjusting screw 323 presses and fixes the assembly plate 1 in the slot 322, thereby initially fixing the assembly plate 1 in the slot 322.

[0057] In one specific embodiment of the present invention, in steps S121 and S122, see... Figure 4 The adjustment frame 3 includes a base 31, a first support plate 32, and a second adjustment component 33. Both the first support plate 32 and the second adjustment component 33 are vertically mounted on the base 31, and the second adjustment component 33 is connected to the first support plate 32. The first support plate 32 is vertically mounted at both ends of the base 31 and includes a main plate 321 and a slot 322. The main plate 321 is vertically mounted on the base 31, and a square groove is provided on the end face of the main plate 321 facing the operator, serving as the second slide rail 3211 of the second adjustment component 33. The slot 322 is used to engage the mounting plate 1 from both ends and is vertically mounted on the main plate 321 and the second slide rail 3211. The vertical surface 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 grooves 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 groove 322. 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 groove 322 for engagement. In order to enable the clamping plate 11 to move stably in the groove 322, the clamping plate 11 can be made to fit against the end face of the groove 322. The movement of the clamping plate 11 in the groove 322 drives the base plate 12 to move synchronously.

[0058] 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.

[0059] Step S13: Support the assembly plate 1; Tighten the second adjusting screw 335 in the threaded hole on the side wall of the moving block 333 to disengage the second adjusting screw 335 from the fixing post 331 in the moving block 333, thereby releasing the relative fixation between the moving block 333 and the fixing post 331. Under the elastic force of the spring 332, the moving block 333 is lifted vertically upward by the spring 332 in a compressed state, so that the limiting block 3331 on the moving block 333 is pushed into the limiting groove 111 on the assembly plate 1 for engagement, thereby supporting the assembly plate 1 through the compression elastic force of the spring 332; During the upward movement of the moving block 333, the intermediate rod 334 connected to the moving block 333 moves along the second slide rail 3211 under the drive of the moving block 333, thereby achieving radial limiting of the moving block 333.

[0060] Step S14: Further fix the assembly plate 1; turn the second adjusting screw 335 in the threaded hole on the side wall of the moving block 333 so that the second adjusting screw 335 approaches and presses against the fixing post in the moving block 333 so that the moving block 333 and the fixing post 331 are fixed relative to each other again, thereby locking and limiting the assembly plate 1 that is engaged with the limiting block 3331 in the vertical direction, and improving the stability of the assembly plate 1 on the adjusting frame 3.

[0061] In one specific embodiment of the present invention, in steps S13 and S14, see... Figure 5 The second adjusting component 33 includes a fixed column 331, a spring 332, a movable block 333, and an intermediate rod 334. The fixed column 331 is a circular cylinder, vertically mounted on the base 31, and the spring 332 is sleeved on the fixed column 331. The movable block 333 is a circular cylinder with a through hole, which is movably sleeved on the fixed column 331 and located above the spring 332, so that the spring 332 can drive the movable block 333 to move vertically through its elastic force. Furthermore, to ensure that the movable block 333 can move stably along the fixed column 331... The fixed movement allows the end face of the fixed post 331 to fit with the through hole of the movable block 333; the intermediate rod 334 is a square rod, with one end connected to the movable block 333 and the other end fitted into the slide rail to radially limit the movable block 333, preventing the movable block 333 from radially deviating during vertical movement along the fixed post 331; to prevent the spring force of the spring 332 from ejecting the movable block 333 from the fixed post 331 from the top, one end of the spring 332 can be fixed to the base 31 or the bottom end of the fixed post 331, and the other end can be connected to the movable block 333.

[0062] See Figure 6The clamping plate 11 has a limiting groove 111 with an open bottom edge 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. In order to further enhance the stability of the assembly plate 1, the side wall of the moving block 333 has a threaded hole communicating with the through hole to install the second adjusting screw 335. Tightening the second adjusting screw 335 can make it press against the fixing post 331 in the moving block 333, thereby fixing the moving block 333 to the fixing post 331.

[0063] Step S2: Assemble the micro rectangular connector

[0064] Step S21: Insert the micro rectangular connector contact body; movably fit the insulator sleeved on the micro rectangular connector contact body to the outer surface of the positioning sleeve 2 through the through hole, so that the insulator is attached to the upper surface of the assembly plate 1, and then insert the contact body into the through hole of the positioning sleeve 2, with the upper end of the contact body inserted into the positioning sleeve 2 protruding from the positioning sleeve 2 and the insulator.

[0065] In one specific embodiment of the present invention, in step S21, see... Figure 2 The base plate 12 is a square plate with a circular groove with an opening at the top. 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. In addition, in order to facilitate the vertical support of the positioning sleeve 2, the distribution of the grooves on the base plate 12 is the same as that of the positioning sleeve 2 and they are connected to the through holes on the clamping plate 11.

[0066] Step S22: Adjust the contact body of the micro rectangular connector; turn the first lead screw 131 in the threaded hole of the clamping plate 11, so that the first lead screw 131 drives the clamping plate 11 to move relative to the base plate 12, thereby adjusting the distance between the clamping plate 11 and the base plate 12, so that the length of the contact body extending into the positioning sleeve 2 changes, realizing the adjustment of the contact body connection length to adapt to micro rectangular connectors with different length requirements; during the movement of the clamping plate 11 relative to the base plate 12, the locking block 133 connected to the clamping plate 11 moves synchronously along the first slide rail 132 under the drive of the clamping plate 11, thereby ensuring that the clamping plate 11 can move in the vertical direction of the base plate 12 and improving the stability of the device.

[0067] In one specific embodiment of the present invention, in step S22, see... Figure 2The 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. The first lead screw 131 drives the clamping plate 11 to move 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.

[0068] 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.

[0069] Step S23: Determine the insertion length of the micro rectangular connector contact body; observe the scale on the plate surface corresponding to the upper or lower edge of the card block 133 located in the square through hole of the second support plate 1322. The scale on the second support plate 1322 represents the length of the contact body inserted into the positioning sleeve 2, thereby determining the insertion length of the micro rectangular connector contact body according to actual needs.

[0070] In one specific embodiment of the present invention, in step S23, the surface of the second support plate 1322 facing the operator is provided with a scale. The scale is arranged along the moving direction of the locking block 133 to indicate the length of the contact body extending into the positioning sleeve 2, so that the operator can accurately grasp the connection size of the contact body.

[0071] Step S24: Assemble the contact body; After crimping the wire to the upper end of the contact body using crimping pliers, apply glue to the insulator and the contact body above the insulator to complete the assembly of the contact body.

[0072] Step S3: Unload the micro rectangular connector;

[0073] Step 31: Disassemble the insulator; Pull the assembled micro rectangular connector insulator upwards to detach it from the positioning sleeve 2. At this time, the insulator and the contact body have been glued together, so that the insulator drives the contact body to detach from the positioning sleeve 2, thus completing the disassembly of the micro rectangular connector.

[0074] Step S32: Remove assembly plate 1;

[0075] Step S321: Unlock the moving block 333; Turn the second adjusting screw 335 and disengage it from the fixed post 331, thereby releasing the lock on the fixed post 331 and allowing the moving block 333 to move vertically along the fixed post 331.

[0076] Step S322: Re-fix the moving block 333; Move the moving block 333 to the bottom of the fixing post 331 and place it under the assembly plate 1. At this time, the limiting block 3331 on the moving block 333 disengages from the limiting groove 111 on the clamping plate 11, and the spring 332 is further compressed. Tighten the second adjusting screw 335 to press and fix it against the fixing post 331, so as to re-fix the moving block 333 on the fixing post 331.

[0077] Step S323: Unlock assembly plate 1; Tighten the first adjusting screw 323 and disengage it from assembly plate 1, thereby releasing the first adjusting screw 323 from locking assembly plate 1, so that assembly plate 1 can move within slot 322.

[0078] Step S324: Re-fix the assembly plate 1; after moving the unlocked assembly plate 1 back into the first support plate 32, turn the first adjusting screw 323 and make it pass through the threaded hole on the third support plate 3221 to re-press and fix the assembly plate 1.

[0079] Step S4: Replace assembly plate 1; When assembling other types of micro rectangular connectors, it is necessary to replace assembly plate 1. Select the corresponding assembly plate 1 according to the micro rectangular connector to be assembled, and then repeat steps S1-S3.

[0080] 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.
