Description

Technical Field

[0001] The present application relates to the technical field of connectors, and in particular to a gap compensating connector. Background Art

[0002] In some cases, two side-by-side components (e.g., two plate-like components) need to be connected together, and a certain gap is to be maintained between the two components. In this case, a gap compensation connector is usually used to connect the two components. The gap compensation connector usually includes a fixing member and an adjusting member that are threaded together. An operating channel is constructed in the adjusting member, and an inner sleeve is installed in the operating channel. The inner sleeve needs to rotate synchronously with the adjusting member so that the adjusting member can be driven to rotate using an adjusting bolt.

[0003] In the prior art, the engagement strength between the inner sleeve and the operating channel is relatively weak. Under the condition of large force, the inner sleeve is easy to rotate relative to the adjusting member, resulting in the gap compensation connector being unable to be used normally.

This reduces the number of parts of the gap compensating connector, simplifies the structure of the gap compensating connector, and thus helps to reduce the manufacturing cost of the gap compensating connector.

[0079] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0080] In the present application, the term "axial direction" refers to a direction substantially parallel to the central axis of the tubular member, and the term "lateral direction" refers to a direction substantially perpendicular to the axial direction.

[0081] Figure 1 The gap compensation connector 1 according to one embodiment of the present application is schematically shown. Figure 1 , Figure 2 and Figure 3 As shown, the gap compensation connector 1 includes a fixing member 2 , an adjusting member 3 assembled with the fixing member 2 , and an elastic sleeve 4 installed in the adjusting member 3 .

[0082] like Figure 2 and Figure 3 As shown, the fixing member 2 is configured with a first channel 21 extending along the axial direction A. The first channel 21 includes a first channel section 211 (eg, Fig.11 For simplicity, the following description will be made by taking the first internal thread 210 as a left-handed thread as an example.

[0083] Also like Figure 2 and Figure 3 As shown, the adjusting member 3 includes a cylindrical body 31. Specifically, as Figure 4 and Figure 5 As shown, the cylindrical body 31 has a pressure-bearing end 313 and an assembly end 314, and a support platform 312 extending radially inward is configured at the assembly end 314. After the adjusting member 3 is assembled to the fixing member 2, the pressure-bearing end 313 is away from the fixing member 2 and is outside the first channel section 211, and the assembly end 314 is inside the first channel section 211 of the fixing member 2. Figure 4 and Figure 5As shown, the interior of the cylindrical body 31 forms a second channel 32 that runs through along the axial direction A. Two grooves 320 are configured on the circumferential side wall of the second channel 32, and the two grooves 320 are opposite to each other along the radial direction of the second channel 32. An external thread 310 matching the first internal thread 210 is configured on the circumferential outer wall of the cylindrical body 31 (that is, the external thread 310 is also a left-handed thread), so that the cylindrical body 31 is threadedly connected to the first channel section 211 and can move axially relative to the fixing member 2.

[0084] like Figure 6 , Figure 8 and Fig. 9 As shown, the elastic sleeve 4 includes an axially extending body 41 and two first elastic fins 421 extending radially outward from the body 41. The two first elastic fins 421 are opposite to each other along the radial direction of the body 41. Fig.10 As shown, the elastic sleeve 4 is assembled in the second channel 32 and supported by the supporting platform 312 , and the two first elastic fins 421 are respectively engaged in the corresponding grooves 320 , so that the adjusting member 3 can rotate synchronously with the elastic sleeve 4 .

[0085] The gap compensation connector 1 of the present application is suitable for connecting two first components 11 and second components 12 (such as Fig.18 The first component 11 may be provided with a first assembly opening (not shown in the figure) corresponding to the first channel 21; the second component 12 may be provided with a second assembly opening (not shown in the figure) corresponding to the second channel 32.

[0086] When the clearance compensation connector 1 is used (ie, when the clearance compensation connector 1 is assembled with the first component 11 and the second component 12), as shown in FIG. Fig.18 As shown, the gap compensation connector 1 is in an initial state. In the initial state, the adjusting member 3 is threadedly connected with the fixing member 2, and the pressure-bearing end 313 of the adjusting member 3 is close to the fixing member 2.

[0087] First, the gap compensation connector 1 is set between the first component 11 and the second component 12. The fixing member 2 is fixedly connected to the first component 11, and the second channel 32 is aligned with the second assembly opening. At this time, the pressure-bearing end 313 is spaced apart from the second component 12. The pressure-bearing end 313 of the adjusting member 3 is spaced apart from the second component 12.

[0088] Then, an adjusting bolt 13 is provided, and the thread of the adjusting bolt 13 is opposite to the first internal thread 210, that is, a right-hand thread. The adjusting bolt 13 is inserted into the elastic sleeve 4 through the assembly opening from the side of the second component 12 away from the first component 11. The adjusting bolt 13 presses the elastic sleeve 4 radially outward and is tightly connected with the elastic sleeve 4. At this time, the bolt head 131 of the adjusting bolt 13 can be spaced apart from the second component 12 (such as Fig.18 shown).

[0089] Next, turn the adjusting bolt 13 clockwise. The adjusting bolt 13 drives the elastic sleeve 4 and the adjusting member 3 to rotate clockwise synchronously. Fig.21 As shown, since the first internal thread 210 and the external thread 310 are left-handed threads, the adjusting member 3 will gradually loosen from the fixing member 2 and gradually move axially away from the fixing member 2 (i.e., move toward the second component 12) until the pressure-bearing end 313 is tightly abutted against the second component 12 (as shown in FIG. Fig.19 shown).

[0090] Next, the adjusting bolt 13 is rotated clockwise. The adjusting bolt 13 moves toward the fixing member 2 along the axial direction A and is finally fixedly connected to the fixing member 2. The bolt head 131 also abuts against the second component 12 (eg, Fig. 20 shown).

[0091] Thus, the gap compensating connector 1 connects the first component 11 and the second component 12 together and maintains a desired gap between the first component 11 and the second component 12. It should be noted that when the gap compensating connector 1 is used, the assembly end 314 is always in the first channel section 211.

[0092] In the gap compensating connector 1 of the present application, the first elastic fin 421 of the elastic sleeve 4 is engaged in the groove 320 of the adjusting member 3, and the groove 320 prevents the first elastic fin 421 (or the elastic sleeve 4) from rotating relative to the adjusting member 3; in addition, the support platform 312 can prevent the elastic sleeve 4 from moving toward the fixing member 2 along the axial direction A, which allows the gap compensating connector 1 to be used smoothly. In addition, from a holistic perspective, the mutual constraint between the elastic sleeve 4 and the adjusting member 3 is achieved through the structure of the two themselves (for example, the groove 320, the support platform 312 and the first elastic fin 421), without the need for additional fixings. This reduces the number of parts of the gap compensating connector 1, simplifies the structure of the gap compensating connector 1, and thus helps to reduce the manufacturing cost of the gap compensating connector 1.

[0093] It should be noted that the adjusting bolt 13 is not an indispensable component of the gap compensation connector 1. Those skilled in the art can select any bolt with appropriate length and thread according to actual conditions.

[0094] The adjusting member 3 and the elastic sleeve 4 will be described below.

[0095] In one embodiment, Figure 4 and Figure 5 As shown, the adjusting member 3 further includes a flange 33 extending radially outward from the pressure-bearing end 313 of the cylindrical body 31. After the clearance compensation connector 1 is assembled with the first component 11 and the second component 12, the flange 33 abuts against the second component 12 (as shown in FIG. Fig. 20 As shown in FIG. 1 , the contact area between the adjusting member 3 and the second component 12 is large, which reduces the stress on the second component 12 and helps to protect the second component 12 .

[0096] Optionally, Figure 5 As shown, the groove 320 extends through the support platform 312 along the axial direction A. In addition, the groove 320 has a closed end 322 corresponding to the pressure-bearing end 313 and an open end 321 corresponding to the assembly end 314. Figure 6 As shown, the body 41 of the elastic sleeve 4 has a first end 411 corresponding to the pressure-bearing end 313 and a second end 412 corresponding to the assembly end 314. The first elastic fin 421 extends toward the first end 411 of the body 41 along the axial direction A. In this way, when assembling the elastic sleeve 4, the elastic sleeve 4 is radially compressed inwardly until its outer diameter is smaller than the inner diameter of the support platform 312, and the first elastic fin 421 is aligned with the open end 321 (or the groove 320), and the elastic sleeve 4 can be slid into the second channel 32 along the axial direction A. This facilitates the assembly of the elastic sleeve 4.

[0097] In addition, if Fig.10 As shown, after the elastic sleeve 4 is assembled into the second channel 32, the first elastic fin 421 abuts against the closed end 322 of the groove 320. This helps prevent the elastic sleeve 4 from excessively moving along the axial direction A toward the pressure-bearing end 31, or even from separating from the adjusting member 3.

[0098] In one embodiment, the circumferential dimension of the first elastic fin 421 matches the circumferential dimension of the groove 320 , which can prevent the elastic sleeve 4 from rotating relative to the adjusting member 3 in the circumferential direction.

[0099] Alternatively, if Figure 6 , Figure 8 and Fig. 9 As shown, the elastic sleeve 4 also includes at least one second elastic fin 422 that is bent radially inward from the body 41. After the adjusting bolt 13 is inserted into the elastic sleeve 4, the adjusting bolt 13 presses the second elastic fin 422 radially outward, so that the second elastic fin 422 is in close contact with the adjusting bolt 13 in the radial direction. In this way, the adjusting bolt 13 can drive the elastic sleeve 4 to rotate, and thereby drive the adjusting member 3 to rotate synchronously. In addition, the second elastic fin 422 has a relatively small strength and is easy to deform radially, so that the adjusting bolt 13 can be easily inserted into the elastic sleeve 4.

[0100] It should be noted that after the pressure-bearing end 313 is tightly abutted against the second component 12 , the adjusting bolt 13 can continue to be rotated clockwise, while the elastic sleeve 4 and the adjusting member 3 no longer rotate (this will be described in detail below).

[0101] Alternatively, Figure 6 , Figure 8 and Fig. 9As shown, there are two second elastic fins 422 and they are opposite to each other along the radial direction of the body 41. Both second elastic fins 422 extend along the axial direction A toward the second end 412 of the body 41 and are radially aligned with the groove 320. In this way, when the adjusting bolt 13 is inserted into the elastic sleeve 4, the groove 320 provides a space for the second elastic fins 422 to deform radially outward, so as to facilitate the insertion of the adjusting bolt 13 into the elastic sleeve 4.

[0102] Optionally, Figure 6 As shown, the first elastic fin 421 and the second elastic fin 422 are located in the middle portion 413 of the body 41. The portion of the second end 412 of the body 41 corresponding to the second elastic fin 422 is continuous along the circumferential direction. This helps to improve the overall strength of the elastic sleeve 4 and prevents the elastic sleeve 4 from being deformed and damaged when the gap compensation connector 1 is used.

[0103] It should be understood that although Figure 6 As shown in the figure, the portion of the first end 411 of the main body 41 corresponding to the first elastic fin 421 is discontinuous in the circumferential direction, but the portion of the first end 411 of the main body 41 can also be constructed to be continuous in the circumferential direction according to actual conditions as long as the free deformation of the first elastic fin 421 is not affected.

[0104] In one embodiment, more first elastic fins 421 may be constructed on the body 41, and these first elastic fins 421 are evenly arranged along the circumferential direction; meanwhile, a corresponding number of grooves 320 are also provided on the circumferential sidewall of the second channel 32. The plurality of first elastic fins 421 are respectively engaged in the corresponding grooves 320. The same is true for the second elastic fins 422, which will not be described in detail here.

[0105] Alternatively, if Figure 6 and Figure 8 As shown, the elastic sleeve 4 further includes a barb 423 extending radially outward from the circumferential outer surface of the body 41. After the elastic sleeve 4 is assembled into the second channel 32, the barb 423 abuts against the circumferential side wall of the second channel 32. In this way, the axial movement resistance of the elastic sleeve 4 is further increased, thereby helping to further prevent the elastic sleeve 4 from axially moving relative to the adjusting member 3.

[0106] In one embodiment, Figure 6As shown, the barb 423 includes a connecting end 424 connected to the body 41 and an abutting end 425 separated from the body 41. The connecting end 424 is close to the second end 412 of the body 41, and the abutting end 425 is close to the first end 411 of the body 41. According to this structure, when the elastic sleeve 4 is pushed toward the pressure-bearing end 313 of the adjusting member 3 along the axial direction A, the abutting end 425 of the barb 423 will be blocked by the adjusting member 3 (or the circumferential side wall of the second channel 32), so that the barb 423 is further radially opened outward. This makes the barb 423 abut against the circumferential side wall of the second channel 32 more closely, thereby further preventing the elastic sleeve 4 from generating the above-mentioned axial movement relative to the adjusting member 3.

[0107] Optionally, Figure 6 and Figure 8 As shown, the barb 423 is staggered with the first elastic fin 421 and the second elastic fin 422 in the circumferential direction, which helps to avoid the local strength of the body 41 being too weak.

[0108] Alternatively, if Figure 7 As shown, the body 41 has two axial edges 414, and the two axial edges 414 are separated from each other along the circumferential direction. As a whole, the elastic sleeve 4 is not closed along the circumferential direction. In this way, when the elastic sleeve 4 is installed in the second channel 32, it can be easily compressed radially inward, so that the installation of the elastic sleeve 4 is easier. After being installed in the second channel 32, the elastic sleeve 4 will automatically open radially outward so that the first elastic fin 421 and the second elastic fin 422 are engaged in the corresponding groove 320. In one embodiment, the elastic sleeve 4 can be made of a bent spring steel plate. Of course, according to actual conditions, the elastic sleeve 4 can also be made of other elastic materials, which are not limited here.

[0109] Also like Figure 7 As shown, each axial edge 414 has a curved section 415, and the curved sections 415 of the two axial edges 414 match each other. Overall, the gap between the two axial edges 414 is curved. When multiple elastic sleeves 4 are stored together, the curved gap between the two axial edges 414 can prevent these elastic sleeves 4 from being interlaced and connected together and difficult to separate.

[0110] Next, the fixing member 2 will be described.

[0111] like Fig.11As shown, the fixing member 2 includes a clamp 22. The clamp 22 has two clamping arms 223 (i.e., a first clamping arm 223a and a second clamping arm 223b) extending in the transverse direction T. The first clamping arm 223a and the second clamping arm 223b are arranged side by side and spaced apart, and a clamping space 229 is formed therebetween. In addition, the first ends of the first clamping arm 223a and the second clamping arm 223b are separated from each other to form a clamping opening 224 of the clamp 22, and the second ends opposite to the first ends are connected to each other through two elastic connecting legs 228. The two connecting legs 228 are also arranged side by side and spaced apart.

[0112] A first tube body 221 is provided on the first clamping arm 223a, and a second tube body 222 is provided on the second clamping arm 223b. The first tube body 221 extends away from the second clamping arm 223b, and forms a first channel section 211 of the first channel 21 therein. The second tube body 222 extends away from the first clamping arm 223a, and forms a second channel section 212 of the first channel 21 therein. The first channel section 211 is aligned with the second channel section 212 along the axial direction A. A second internal thread (not shown) is configured in the second channel section 212, and the rotation direction of the second internal thread is opposite to that of the first internal thread 210; that is, the second internal thread is a right-handed internal thread, which matches the external thread of the adjusting bolt 13.

[0113] In one embodiment, the first tube body 221 and the first clamping arm 223a are integrally formed. Of course, the first tube body 221 and the first clamping arm 223a can also be formed separately and then connected together. The same is true for the second clamping arm 223b and the second tube body 222, which will not be repeated here.

[0114] It should be understood that the first tube body 221 and the second tube body 222 (ie, the first channel 21 ) may also be both disposed on the first clamping arm 223 a , or both disposed on the second clamping arm 223 b .

[0115] When using the clearance compensation connector 1, Fig.18 As shown, the first clamping arm 223a and the second clamping arm 223b are clamped on the first component 11 to achieve fixed connection between the fixing member 2 and the first component 11. The first tube 221 faces the second component 12, and the second tube 222 faces away from the second component 12 (ie, away from the adjusting member 3).

[0116] like Fig. 20As shown, after the adjusting member 3 abuts against the second component 12, the driving force continues to be applied to the adjusting bolt 13 in the clockwise direction to break the holding force of the second elastic fin 422 on the adjusting bolt 13. In this way, the adjusting bolt 13 will rotate clockwise relative to the adjusting member 3 and the elastic sleeve 4 (at this time, the adjusting member 3 and the elastic sleeve 4 do not rotate), and finally be threadedly connected with the second channel section 212. As a result, the adjusting bolt 13 will always be stably located in the first channel 21 and maintain close contact with the elastic sleeve 4 (or the second elastic fin 422), which can prevent the adjusting member 3 from loosening from the second component 12.

[0117] Alternatively, if Fig.12 As shown, at least part of the second channel section 212 is configured as a non-circular profile. When the clearance compensation connector 1 is used, the adjusting bolt 13 will still rotate through the second channel section 212 and force the second channel section 212 to deform into a circle, so that the second channel section 212 will clamp the adjusting bolt 13, so that the connection between the adjusting bolt 13 and the second channel section 212 is more stable. In one embodiment, the entirety or the end of the second channel section 212 can be configured as an ellipse, or other non-circular profiles.

[0118] Optionally, Fig.11 and Fig.13 As shown, an anti-slipping block 225 is configured on the first clamping arm 223a. The anti-slipping block 225 extends laterally away from the clamping opening 224 of the clamp 22. After the fixing member 2 is fixed to the first component 11, the anti-slipping block 225 abuts against the corresponding baffle 111 on the first component 11. This can prevent the fixing member 2 from falling off from the first component 11 along the extending direction of the anti-slipping block 225.

[0119] Next, the retaining sleeve 5 will be described.

[0120] like Figure 2 and Fig.13 As shown, the retaining sleeve 5 is assembled on the fixing member 2, for example, the retaining sleeve 5 is sleeved on the first tube body 221. Fig.14 and Fig.17 As shown, the retaining sleeve 5 includes an annular main body 51 , which is sleeved on the first tube body 221 of the first clamping arm 223 a of the fixing member 2 , thereby surrounding the first channel 21 .

[0121] In one embodiment, Fig.14 As shown, two lugs 514 extending radially outward are formed on the radial outer surface of the annular body 51, and the two lugs 514 are radially opposite to each other. Two claws 227 (such as Fig.11As shown in FIG. 2 , after the retaining sleeve 5 is sleeved onto the first tube body 221 , the two claws 227 are respectively connected to the corresponding lugs 514 , so that the retaining sleeve 5 is stably assembled on the fixing member 2 .

[0122] Also like Fig.14 and Fig.16 As shown, the retaining sleeve 5 also includes a limit plate 511 extending from the annular body 51 toward the adjusting member 3 and a limit column 512 extending from the annular body 51 toward the adjusting member 3. As a whole, the limit column 512 is spaced apart from the limit plate 511 along the circumferential direction of the retaining sleeve 5. The flange 33 of the adjusting member 3 matches the retaining sleeve 5. A limit protrusion 331 extending toward the retaining sleeve 5 is constructed on the flange 33. In the initial state of the clearance compensation connector 1, the limit protrusion 331 is between the limit plate 511 and the limit column 512, and as the adjusting member 3 rotates, the limit protrusion 331 can be stopped by the limit plate 511 or the limit column 512.

[0123] For example, in the initial state of the gap compensation connector 1, when the adjustment member 3 is accidentally rotated out of the fixing member 2 in the clockwise direction (for example, when the adjustment member 3 rotates clockwise due to shaking during transportation), the limit plate 511 will block the limit protrusion 331 to prevent the adjustment member 3 from further rotating clockwise, thereby preventing the adjustment member 3 from accidentally rotating out of the fixing member 2. It should be understood that the limit plate 511 is relatively weak (for example, it has appropriate elasticity). When the gap compensation connector 1 is used normally, the operator can easily rotate the limit protrusion 331 clockwise to pass through the limit plate 511 to complete the installation of the gap compensation connector 1.

[0124] For another example, in the initial state of the clearance compensation connector 1, when the adjusting member 3 is screwed into the fixing member 2 in the counterclockwise direction (for example, when the adjusting member 3 and the fixing member 2 are preassembled together; or when the adjusting member 3 rotates counterclockwise due to shaking during transportation), the limiting column 512 will block the limiting protrusion 331 to prevent the adjusting member 3 from further rotating counterclockwise and being too tightly connected to the fixing member 2. It should be understood that when the clearance compensation connector 1 is used normally, after the adjusting member 3 is rotated clockwise to pass through the limiting plate 511, the adjusting member 3 moves away from the retaining sleeve 5 along the axial direction A, so that the limiting protrusion 331 no longer conflicts with the limiting column 512, so that the adjusting member 3 can be rotated continuously clockwise.

[0125] Optionally, Fig.15As shown, the retaining sleeve 5 also includes an anti-fool-proofing protrusion 513. The anti-fool-proofing protrusion 513 protrudes from the annular body 51 toward the fixing member 2 along the axial direction A. A receiving space 226 matching the anti-fool-proofing protrusion 513 is provided on the fixing member 2. After the retaining sleeve 5 is installed on the fixing member 2, the anti-fool-proofing protrusion 513 enters the receiving space 226. In this way, when assembling the clearance compensation connector 1, it can be ensured that the retaining sleeve 5 is correctly installed on the fixing member 2, so that the limiting plate 511 and the limiting column 512 can correctly constrain the adjusting member 3. In one embodiment, as Fig.11 As shown, the claw 227 is located between two connecting legs 228 of the clamp 22 , and the above-mentioned accommodating space 226 is formed between the claw 227 and the corresponding connecting leg 228 .

[0126] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
