[0002] Under the existing technical conditions, the assembly of the clamp ring of the connector housing is completely dependent on the employee's skill operation. The left hand fixes the product shell, and then installs the spring, retaining ring, and clamp ring in turn.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] like Figure 1 and Figure 2 As shown, a blind-insertion assembly device of a connector shell 54 and a clamping ring 51 includes a pressing component and a shell positioning component; the shell positioning component is mainly used to install the shell 54 so that the position of the clamping ring 51 can remain stable during installation, and the pressing component first squeezes the clamping ring 51 so that the clamping ring 51 shrinks inward, and then pushes the clamping ring 51 downward in the shell 54, and finally makes the clamping ring 51 stuck in the clamping groove 53 of the shell 54. Specifically, it is described in detail in combination with the structure of the pressing component and the shell positioning component.

[0024] In this embodiment, if Figure 3 As shown, the pressing assembly includes a gantry 18, a pressing shaft 1, a pressing cylinder 2 and a claw assembly 3. Figure 6 , Figure 7 and Figure 8As shown, the claw assembly 3 includes a mounting plate 31 and a cover plate 38. A connecting tube 35 is provided at the bottom of the mounting plate 31. Preferably, the mounting plate 31 is a circular plate. A plurality of split grooves arranged at intervals are provided at the bottom of the connecting tube 35 from bottom to top, so that an elastic claw 36 is formed at the bottom of the connecting tube 35. Furthermore, the split grooves are evenly distributed on the same circumference. When the elastic claw 36 is subjected to a radially inward force, the elastic claw 36 will shrink inward, and when the external force disappears, the elastic claw 36 can be reset. In this embodiment, at least two mounting grooves 32 evenly distributed on the same circumference are provided at the top of the mounting plate 31. Preferably, there are four mounting grooves 32, that is, the four mounting grooves 32 are distributed in a cross shape, and a limiting hole is provided on the side wall outside the mounting groove 32. The limiting hole extends radially outward and passes through the outer wall of the mounting plate 31. A ball 34 is installed in the mounting groove 32. The cam 33 is pressed against the top of the mounting plate 31 and the cam 33 is pressed against the top of the mounting plate 31. The cam 33 is pressed against the top of the mounting plate 31 and the cam 33 is pressed against the top of the mounting plate 31.

[0025] In this embodiment, if Figure 1 and 2As shown, the gantry 18 mainly plays a supporting role. A limiting cylinder 4 is installed on the top of the cross beam 12 of the gantry 18. A compression spring 5 is installed in the limiting cylinder 4. Preferably, the limiting cylinder 4 and the cross beam 12 are integrally formed. The bottom of the pressing shaft 1 passes through the pressing cylinder 2, the claw assembly 3, the compression spring 5 and the cross beam 12 in sequence. A convex ridge 14 is provided on the inner side wall of the bottom of the pressing cylinder 2. The circumferential diameter of the inner side wall of the convex ridge 14 matches the outer diameter of the mounting plate 31, and the lower side wall of the convex ridge 14 has a guiding inclined surface 16. The outer diameter of the mounting plate 31 is larger than the inner diameter of the limiting cylinder 4.During installation, the compression spring 5 is first placed in the limiting cylinder 4. When the compression spring 5 is subjected to an axial downward force, the compression spring 5 is compressed, and the limiting cylinder 4 can limit the compression spring 5, thereby ensuring the reliability of the compression of the compression spring 5. Then, the bottom of the pressing shaft 1 is passed through the pressing cylinder 2, the claw assembly 3, the compression spring 5 and the crossbeam 12 in sequence. That is to say, a center hole is provided on the pressing cylinder 2, and a center hole is also provided on the cover plate 38 and the mounting plate 31. A hole is also provided on the crossbeam 12, and these holes are coaxially arranged. In this embodiment, a locking assembly is provided between the pressing shaft 1 and the pressing cylinder 2. When the locking assembly is locked When the locking assembly is unlocked, the pressing shaft 1 drives the pressing cylinder 2 to move downward. When the locking assembly is unlocked, the pressing shaft 1 and the pressing cylinder 2 can move relatively independently. Therefore, when in use, in the initial stage, the pressing shaft 1 and the pressing cylinder 2 are in a locked state, and downward pressure is applied to the pressing shaft 1, and the pressing shaft 1 drives the pressing cylinder 2 to move downward, thereby driving the claw assembly 3 downward. At this time, the radial inward external force on the ball 34 is very small, so the position of the ball 34 is almost unchanged. Therefore, the pressing cylinder 2 moves downward, which can drive the claw assembly 3 downward. When the mounting plate 31 abuts against the bottom of the limiting cylinder 4, the compression spring 5 is at its maximum compression. The compression spring 5 will give the mounting plate 31 an axial force in the The force on the mounting plate 31 is exerted on the bottom of the limiting cylinder 4. As the pressing shaft 1 is continuously pressed downward, the ball 34 is subjected to a radially inward force and is able to overcome the elastic force of the top pressure spring 33, thereby causing the ball 34 to move along the guide inclined surface 16 of the convex ridge 14. When the ball 34 enters the limiting hole, the claw assembly 3 moves upward rapidly under the action of the compression spring 5 and quickly moves to the top of the inner cavity of the pressing cylinder 2. The operator can distinguish by listening to the collision sound between the claw assembly 3 and the pressing cylinder 2. In this embodiment, a shock-absorbing pad is installed on the top of the inner cavity of the pressing cylinder 2. Preferably, the shock-absorbing pad is a rubber pad, which can ensure that the card The claw assembly 3 does not cause damage after colliding with the pressing cylinder 2. When the claw assembly 3 collides with the pressing cylinder 2, the first stage of the downward movement of the lower pressing shaft 1 is completed. At this time, the clamping ring 51 is completely retracted inward, and then the pressing shaft 1 and the pressing cylinder 2 are unlocked, and then the pressing shaft 1 can continue to move downward. As the pressing shaft 1 continues to move downward, the clamping ring 51 is pushed downward. When the clamping ring 51 moves to the position of the card slot 53 of the housing 54, the clamping ring 51 is stuck in the card slot 53 under the action of its elastic force, thereby completing the assembly of the clamping ring 51 and the housing 54. Whether the clamping ring 51 is stuck in the card slot 53 can be judged by the collision sound of the clamping ring 51 and the card slot 53. ;

[0026] In this embodiment, if Figure 1 and Figure 2 As shown, the housing positioning assembly includes a bottom plate 8, a positioning cylinder 7 and a positioning sleeve 6. The positioning cylinder 7 is installed on the bottom plate 8. The bottom of the housing 54 is sleeved in the positioning cylinder 7. The top of the housing 54 is sleeved in the positioning sleeve. The diameter of the central through hole of the positioning sleeve 6 matches the diameter of the central through hole of the housing 54. Fig. 9 As shown, a tapered hole 61 is provided at the top of the positioning sleeve 6, the opening diameter of the tapered hole 61 is larger than the diameter of the retaining ring 51, and the tail diameter of the tapered hole 61 is smaller than the diameter of the retaining ring 51; the gantry 18 is installed on the base plate 8, and the pressure shaft 1 is coaxially arranged with the positioning sleeve 6. During installation, after the shell positioning assembly and the pressing assembly are installed, the spring and the washer 52 are sequentially loaded into the positioning sleeve 6, and then the retaining ring 51 is placed into the tapered hole 61, and then the pressing assembly is moved downward again, thereby clamping the retaining ring 51 in the clamping groove 53.

[0027] In this embodiment, the number of ridges 14 corresponds to the number of mounting grooves 32 of the claw assembly 3, and an avoidance gap 15 through which the ball 34 can pass is formed between two adjacent ridges 14. Preferably, the number of mounting grooves 32 is four, and therefore the number of ridges 14 is also four. When the ball 34 passes through the guide slope 16 and enters the inner cavity of the pressing cylinder 2, the pressing cylinder 2 is rotated so that the ball 34 is aligned with the avoidance gap 15, thereby removing the mounting plate 31 from the pressing cylinder 2.

[0028] In this embodiment, if Figure 1 and Figure 3 As shown, the lock assembly includes a limit block 19 and a retreat groove. A plurality of retreat grooves are provided on the top of the pressing cylinder 2, and the retreat grooves are spaced apart on the circumference. A limit block 19 corresponding to the retreat groove is provided on the pressing shaft 1. When the limit block 19 is located in the corresponding retreat groove, the pressing cylinder 2 and the pressing shaft 1 are unlocked. That is to say, when the limit block 19 is misaligned with the retreat groove, when the pressing shaft 1 moves downward, the limit block 19 abuts against the top of the pressing cylinder 2, thereby driving the pressing cylinder 2 downward. When the limit block 19 is aligned with the retreat groove, the limit block 19 can pass through the retreat groove. At this time, the pressing shaft 1 can continue to move downward, while the pressing cylinder 2 will not move downward with the pressing shaft 1. In this embodiment, in order to facilitate the unlocking of the lock assembly, an anti-slip pattern 17 is provided on the outer wall of the pressing cylinder 2, so that the operator can easily rotate the pressing cylinder 2, thereby aligning the limit block 19 with the retreat groove.

[0029] In this embodiment, if Figure 2 As shown, a raised hemisphere is provided at the bottom of the pressure shaft 1, and the hemisphere and the top of the pressure shaft 1 form a limiting step. Preferably, the diameter of the hemisphere is larger than the diameter of the inner ring of the gasket 52. Therefore, when the pressure shaft 1 is in the downward process, when the hemisphere abuts against the gasket 52, it will drive the gasket 52 downward, thereby compressing the spring. In addition, when the pressure shaft 1 is in the downward process, it will also drive the clamping ring 51 downward, and the clamping ring 51 and the gasket 52 are not in contact during the initial downward process. When the clamping ring 51 enters the clamping groove 53, after the pressure shaft 1 moves upward, the gasket 52 moves upward under the action of the elastic restoring force of the spring and abuts against the clamping ring 51.

[0030] In this embodiment, if Fig. 9As shown, the bottom of the central through hole of the positioning sleeve 6 is a radially outwardly extending mounting hole 62, and the top of the shell 54 is fitted and mounted in the mounting hole 62, thereby facilitating the assembly of the shell 54 and the positioning sleeve 6. Furthermore, through the fitting relationship between the shell 54 and the mounting hole 62, the coaxiality of the shell 54 and the positioning sleeve 6 can be ensured.

[0031] In this embodiment, due to the presence of the gantry 18, the mounting sleeve and the mounting cylinder are located below the crossbeam 12 when the clamp ring 51 is installed, which makes it inconvenient to install the housing 54, the mounting sleeve, the mounting cylinder, the clamp ring 51, the washer 52 and the spring. Therefore, in this embodiment, Fig.10 As shown, a slide groove 10 is provided on the bottom plate 8 in the radial direction, and the bottom of the positioning cylinder 7 is slidably fitted in the slide groove 10. The positioning cylinder 7 can slide in the slide groove 10, so that the positions of the positioning cylinder 7 and the gantry 18 are staggered, thereby facilitating the assembly of various parts. Furthermore, in order to improve the linearity of the movement of the positioning cylinder 7 and to ensure the coaxiality of the positioning cylinder 7 and the pressure shaft 1, a sliding limiter 11 is axially installed at the bottom of the positioning cylinder 7, and a sliding hole 13 matching the sliding limiter 11 is provided at the bottom of the slide groove 10. Through the cooperation between the sliding limiter 11 and the sliding hole 13, the positioning cylinder 7 can only move in a straight line, and when the sliding limiter 11 is located under the cross beam 12 and the side wall of the sliding hole 13 is in contact, the positioning cylinder 7 is just coaxial with the pressure shaft 1, which makes the shell positioning assembly extremely convenient to use.

[0032] In this embodiment, preferably, the sliding limit member 11 is a screw, and a receiving groove is opened at the bottom of the base plate 8. The head of the screw is located in the receiving groove, and the sliding hole 13 matches the rod of the screw. When the screw is installed, the head of the screw is as close to the bottom of the receiving groove as possible, but the head of the screw cannot abut against the bottom of the receiving groove, thereby ensuring that the positioning cylinder 7 can move while ensuring that the positioning cylinder 7 always moves under the restriction of the sliding groove 10.

[0033] In this embodiment, if Figure 1 As shown, a handle 9 extending radially is installed on the side wall of the positioning cylinder 7, and the radial extension direction of the handle 9 is consistent with the radial extension direction of the sliding groove. By pushing and pulling the handle 9, the positioning cylinder 7 is moved in the sliding groove 10, so that the positioning cylinder 7 is easy to move.

[0034] The working process of the present invention is as follows: first assemble the housing positioning assembly and the pressing assembly, then install the spring and the washer 52 into the positioning sleeve 6 in sequence, and then put the clamping ring 51 into the tapered hole 61, apply downward pressure to the pressing shaft 1, and the pressing shaft 1 drives the pressing cylinder 2 to move downward, thereby driving the claw assembly 3 downward. At this time, the radial inward external force on the ball 34 is very small, so the position of the ball 34 is almost unchanged, so the pressing cylinder 2 moves downward, which can drive the claw assembly 3 downward, and the claw assembly 3 moves downward. During the downward movement of the claw assembly 3, the clamping ring 51 is pushed downward, and when the clamping ring 51 moves downward, the clamping ring 51 contracts inwardly under the action of the tapered hole 61, thereby generating an elastic restoring force. When the clamping ring 51 enters the center hole of the mounting sleeve, the mounting plate 31 is at the same time as the mounting plate 31. The bottom of the limiting cylinder 4 is abutted. Furthermore, during the downward movement of the elastic claw 36, due to the existence of the tapered hole 61, the elastic claw 36 will also shrink inwardly. When in use, in order to prevent the elastic claw 36 from hugging the pressure shaft 1, the wall thickness of the elastic claw 36 can be made thin, but its structural strength will be affected. Therefore, preferably, an upward inclined surface is provided on the inner side wall of the elastic claw 36, which can ensure the structural strength of the elastic claw 36 while preventing the elastic claw 36 from hugging the pressure shaft 1. When the mounting plate 31 is in contact with the bottom of the limiting cylinder 4, the compression spring 5 is at its maximum compression amount. The compression spring 5 will give the mounting plate 31 an axial upward force. Moreover, when the mounting plate 31 is in contact with the bottom of the limiting cylinder 4, as the pressure shaft 1 continues to be pressed downward, the ball 34 is radially The inward force can overcome the elastic force of the top pressure spring 33, thereby causing the ball 34 to move along the guide slope 16 of the convex ridge 14. When the ball 34 enters the limiting hole, the claw assembly 3 moves upward quickly under the action of the compression spring 5, and quickly moves to the top of the inner cavity of the pressing cylinder 2. The operator can judge by listening to the collision sound of the claw assembly 3 and the pressing cylinder 2. When the claw assembly 3 collides with the pressing cylinder 2, the first stage of the downward movement of the lower pressing shaft 1 is completed. At this time, the clamping ring 51 is retracted inwardly, and the clamping ring 51 enters the center hole of the installation sleeve, and then the pressing shaft 1 and the pressing cylinder 2 are unlocked, and then the pressing shaft 1 continues to move downward, and the hemisphere contacts the washer 52 first, thereby pushing the washer 52 downward. As the pressing shaft 1 continues to descend, the pressing shaft 1, the limiting step on the collar 51 pushes the collar 51 downward, and when the collar 51 moves to the position of the slot 53 of the shell 54, the collar 51 is stuck in the slot 53 under the action of its elastic force, thereby completing the assembly of the collar 51 and the shell 54, and whether the collar 51 is stuck in the slot 53 can be judged by the collision sound of the collar 51 and the slot 53, and then the shaft 1 is pressed upward, and the washer 52 is pressed against the washer 52 under the action of the spring. In this embodiment, the washer 52 has a conical surface and a tapered surface. When the washer 52 is in contact with the collar 51, the conical surface of the washer 52 is located inside the collar 51, and the collar 51 is sleeved on the tapered surface. That is to say, when the washer 52 is stuck in the slot 53, at this time, the inner diameter of the washer 52 is smaller than the diameter of the center hole of the shell 54.
