Description

TECHNICAL FIELD

[0001] The present application relates to a connector. BACKGROUND

[0002] The prior art connector for outdoor wiring connection has a structure as shown in Figure 1 and Figure 2 The connector comprises an insulator 101, two wire barrel through holes 102 are formed in the insulator 101, a wire barrel 103 is fixedly and rotatably arranged in the wire barrel through hole 102, a conductor through hole 104 is formed in the wire barrel 103 for the conductor to pass through, and a threaded hole is formed in the wall of the wire barrel 103. A through channel 105 is formed in the insulator 101 at a position corresponding to the threaded hole. During assembly, the wire barrel 103 is fixedly and rotatably arranged in the wire barrel through hole 102, the wire pressing screw 106 is screwed into the wire barrel 103 through the through channel 105, the conductor is passed into the wire barrel 103, and the wire pressing screw 106 presses the conductor against the wire barrel 103.

[0003] Before the prior art connector is shipped, in order to prevent the wire pressing screw 106 from falling off during transportation, the wire pressing screw 106 needs to be screwed into the wire barrel 103, and at this time, the head of the wire pressing screw 106 usually protrudes from the inner wall of the wire barrel 103 and is located in the conductor through hole 104. When wiring (especially large gauge wire), the wire pressing screw 106 needs to be withdrawn first until the head of the wire pressing screw 106 does not protrude from the inner wall of the wire barrel 103, and then the wire can be smoothly passed into the wire barrel 103.

[0004] However, the existing problem is that the connector of the prior art does not have a screw anti-falling structure, and when the wire pressing screw 106 is withdrawn, the wire pressing screw 106 can be directly screwed out of the wire barrel 103 and fall off. The user needs to screw the wire pressing screw 106 into the wire barrel 103 again, and when working at a high altitude, the wire pressing screw 106 may fall from a high place after falling off, which has the risk of being lost, and the use is not convenient. SUMMARY

[0005] The purpose of the present application is to provide a connector to solve the technical problem that the wire pressing screw is easily screwed out and falls off when withdrawn in the prior art.

[0006] To achieve the above purpose, the technical scheme of the connector of the present application is as follows: a connector comprising:

[0007] an insulator,

[0008] a through channel is formed on the insulator, the through channel intersects with the wire barrel through hole, and the through channel is used for the wire pressing screw to pass through and penetrate the wall of the wire barrel to press and assemble the conductor in the wire barrel;

[0009] The insulator is provided with an axial stop portion corresponding to the through passage, and the axial stop portion is used to stop the crimping screw in the axial direction to prevent the crimping screw from being pulled out of the through passage in the axial direction.

[0010] The beneficial effects of the present application are that the axial stop portion can prevent the crimping screw from being completely pulled out of the insulator when the crimping screw is pulled back from the crimping barrel, thereby causing the crimping screw to be lost due to falling off, and that when the force applied to the crimping screw does not exceed the breaking force that the axial stop portion can withstand, the axial stop portion will not be damaged, and the crimping screw will not be pulled out of the connector.

[0011] As a further optimized scheme, the connector comprises the crimping barrel, the barrel wall of the crimping barrel is provided with a through hole through which the crimping screw passes, and the through hole or the through passage of the crimping barrel is provided with an internal thread segment, and the crimping screw is screwed into the internal thread segment; in the axial direction of the crimping screw, the distance between the axial stop portion and the internal thread segment satisfies the following condition: when the axial outer end of the crimping screw is stopped by the axial stop portion, the crimping screw is still screwed with the internal thread segment.

[0012] The effect of this scheme is that the crimping screw is always screwed with the internal thread segment, and the crimping screw is not easy to be skewed in the radial direction, and even if a process hole is formed on the insulator, the crimping screw will not be pulled out.

[0013] As a further optimized scheme, the connector comprises the crimping barrel, the barrel wall of the crimping barrel is provided with a through hole through which the crimping screw passes, and the through hole or the through passage of the crimping barrel is provided with an internal thread segment, and the crimping screw is screwed into the internal thread segment; in the axial direction of the crimping screw, the distance between the axial stop portion and the internal thread segment satisfies the following condition: when the axial outer end of the crimping screw is stopped by the axial stop portion, the crimping screw is still screwed with the internal thread segment.

[0014] The effect of this scheme is that when the crimping screw is stopped by the axial stop portion, the crimping screw is no longer screwed with the internal thread segment, and at this time, no matter how the crimping screw is rotated, the crimping screw will not continue to move towards the direction of the axial stop portion, thereby avoiding damage to the axial stop portion.

[0015] As a further optimized scheme, the insulator is provided with a process hole on one side of the crimping screw, and the process hole communicates the through passage with the outside of the insulator.

[0016] The insulator or the crimping barrel is provided with a radial stop portion, and the radial stop portion is used to stop the crimping screw in the radial direction of the crimping screw after the crimping screw is unscrewed from the internal thread segment to prevent the crimping screw from swinging out of the process hole.

[0017] The effect of the present solution is that the process opening is provided to facilitate the formation of the through passage on the insulator, and the radial stop portion cooperates with the crimping screw to prevent the crimping screw from swinging out of the process opening.

[0018] As a further optimized solution, the through hole of the crimping barrel is a threaded hole, and an internal thread segment is formed on the threaded hole

[0019] The crimping screw comprises a threaded segment and a smooth rod segment located at the end of the threaded segment away from the axial stop portion.

[0020] The radial stop portion comprises a hole wall of the threaded hole, which is used for radial stop cooperation with the smooth rod segment.

[0021] The effect of the present solution is that the smooth rod segment is provided on the crimping screw to prevent the crimping screw from damaging the axial stop portion, and the cooperation between the smooth rod segment and the hole wall of the threaded hole prevents the crimping screw from swinging out.

[0022] As a further optimized solution, the radial stop portion comprises a lateral stop edge provided at the process opening, which is used for stop cooperation with the crimping screw.

[0023] The effect of the present solution is that the lateral stop edge provided at the process opening can prevent the crimping screw from swinging out of the process opening.

[0024] As a further optimized solution, the lateral stop edge is integrally formed on the insulator.

[0025] The effect of the present solution is that the lateral stop edge is integrally formed on the insulator, which facilitates processing.

[0026] As a further optimized solution, the axial stop portion is a stop cantilever integrally formed on the insulator.

[0027] As a further optimized solution, a plurality of crimping screws are provided on the crimping barrel, and the plurality of crimping screws are arranged in sequence along the axial direction of the crimping barrel.

[0028] The plurality of crimping screws share one through passage.

[0029] A stop wall is arranged between any two adjacent crimping screws, the stop wall is provided on the insulator, and the stop wall is used for stop cooperation with the crimping screw to prevent the crimping screw from tilting towards the adjacent crimping screw.

[0030] The effect of the present solution is that after the stop wall is provided, it can prevent one of the crimping screws from leaving a cavity in the insulator after being screwed into the crimping barrel, and the adjacent two crimping screws tilt towards the cavity, so that the crimping screw is always aligned with the corresponding threaded hole on the crimping barrel.

[0031] As a further optimized solution, the axial stop portion is integrally formed on the insulator, and the wire crimping barrel through-hole is used for the wire crimping barrel equipped with a wire crimping screw to penetrate.

[0032] The effect of this solution is that the axial stop portion is integrally formed on the insulator, which is convenient for processing.

[0033] As a further optimized solution, the wire pressing barrel is provided with a plurality of wire pressing screws, and the plurality of wire pressing screws are arranged in sequence along the axial direction of the wire pressing barrel;

[0034] A plurality of the wire-pressing screws share one through passage;

[0035] Two adjacent wire-pressing screws share one axial stop portion.

[0036] The effect of this solution is that the two wire-pressing screws share one axial stop portion, which saves materials and facilitates processing. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] In order to make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus comprising the element.

[0055] The features and performance of the present invention are further described in detail below with reference to the embodiments.

[0056] Specific embodiment 1 of the connector of the present invention:

[0057] like Figures 3 to 5 As shown, the connector includes an insulator 201, in which a wire pressing barrel 203 is installed, and a wire pressing screw 205 is threadedly installed on the barrel wall of the wire pressing barrel 203. There is an axial stopper on the insulator 201 that can limit the retreat limit of the wire pressing screw 205, thereby preventing the wire pressing screw 205 from falling out.

[0058] There are two wire barrel through holes 202 on the insulator 201. The two wire barrel through holes 202 are arranged in an array around the axis of the insulator 201 and have the same structure. In this embodiment, only one of them is used as an example for explanation. There is a conductor through hole 204 in the wire barrel 203 for the conductor to pass through and conduct with the wire barrel 203. A threaded hole 209 is opened on the wall of the wire barrel 203, and a wire screw 205 is threaded through the threaded hole 209. Figure 5 As shown, the wire barrel 203 has a special-shaped outer periphery, and the wire barrel through-hole 202 can be adapted to be inserted into the wire barrel 203, so that the wire barrel 203 is fixedly inserted into the wire barrel through-hole 202. In actual production, in order to ensure the fixed installation of the wire barrel 203 and the insulator 201, methods such as gluing or pressing the two ends can be used, which is not limited in this embodiment.

[0059] like Figure 3 and Figure 4 As shown, the insulator 201 in this embodiment is an integrally cast structure, and a through channel 206 is provided on the insulator 201. The through channel 206 is used for the crimping screw 205 to pass through, and the through channel 206 connects the crimping barrel through hole 202 and the outside of the insulator 201. Figure 3It can be seen that in this embodiment, the two wire pressing screws 205 located on the same side of the wire pressing barrel 203 share a through channel 206, which reduces the number of through channels 206 and facilitates processing. Since the insulator 201 is integrally cast, a demoulding notch 211 is provided on the through channel 206 to facilitate demoulding when the through channel 206 is formed. Figure 4 As shown, the demoulding notch 211 is arranged flush with the end of the wire barrel 203 on one side of the side wall facing the wire barrel 203. The axial stop portion here is a stop cantilever 207 integrally formed on the insulator 201. The stop cantilever 207 can stop the wire barrel 205 when the wire barrel 205 is withdrawn from the threaded hole 209.

[0060] like Figure 4 As shown, in this embodiment, the threaded hole 209 in the wire pressing barrel 203 is threaded throughout, and the wire pressing screw 205 is also threaded throughout. In the axial direction of the wire pressing screw 205, the distance L1 between the stop cantilever 207 and the end face of the wire pressing barrel 203 is less than the axial length L2 of the wire pressing screw 205. The purpose of this arrangement is that when the wire pressing screw 205 retreats to a position where it is stopped by the stop cantilever 207, the wire pressing screw 205 is still threadedly engaged with the wire pressing barrel 203, and the wire pressing screw 205 will not be completely loosened, thereby preventing the wire pressing screw 205 from swinging out of the demoulding notch 211.

[0061] like Figure 4 As shown, in order to facilitate the screwdriver to tighten the wire-pressing screw 205, a screwdriver channel 208 is opened on one side of the blocking cantilever 207. The screwdriver channel 208 can allow the screwdriver to pass through, but is too small to allow the wire-pressing screw 205 to pass through.

[0062] The assembly process of the connector in this embodiment is as follows Figure 5 As shown, here only two wire pressing screws 205 of a side are described as an example, two wire pressing screws 205 are penetrated in the threaded hole 209 of wire pressing barrel 203, screwed forward after penetrating, reduce the length that wire pressing screw 205 is exposed outside wire pressing barrel 203.After wire pressing screw 205 is installed to wire pressing barrel 203, wire pressing barrel assembly 210 is formed, wire pressing barrel assembly 210 is penetrated in the wire pressing barrel perforation 202 of insulator 201, and both are stopped and fixed when penetrating, and through passage 206 is corresponding with two wire pressing screws 205 after penetrating.Then with screwdriver, wire pressing screw 205 is retreated from wire pressing barrel 203, until wire pressing screw outer end face 2051 stops and cooperates with stop cantilever 207, now, wire pressing screw 205 is still threadedly matched with wire pressing barrel 203, and wire pressing screw inner end face 2052 can not protrude in conductor perforation 204.

[0063] When crimping the conductor, the conductor is inserted into the conductor through-hole 204 and the crimping screw 205 is screwed to crimp the conductor. When reworking or replacing the cable, as long as the force applied to the crimping screw 205 does not exceed the destructive force that the stopping cantilever 207 can withstand, the crimping screw 205 will remain in this position and will not be lost.

[0064] In fact, during actual production, there is no limitation on the relative position between the side wall of the demoulding notch 211 facing the wire pressing barrel 203 and the port of the wire pressing barrel 203. The two can be arranged flush or staggered. Since the wire pressing screw 205 is always threaded with the wire pressing barrel 203, the position of the side wall will not affect the wire pressing screw 205.

[0065] In this embodiment, the demoulding notch 211 is an integrally formed process opening, and the process opening corresponds to the wire-pressing screw.

[0066] Depend on Figure 3 and Figure 4 It can be seen that, in this embodiment, the two wire-pressing screws share one axial stop portion.

[0067] It should be noted that this embodiment only introduces the structure of the crimped conductor, and other structures in the connector, such as cable fixing and waterproof structure, are not limited.

[0068] In this embodiment, the threaded hole 209 on the wire barrel 203 is for the wire screw 205 to penetrate, thereby forming a through hole of the wire barrel 203. The threaded hole 209 is entirely an internal thread segment. The installation of the wire screw 205 is achieved by mating with the threaded hole 209. The inner wall of the through channel 206 is smooth and has a threaded mating relationship with the wire screw 205.

[0069] Specific embodiment 2 of the connector of the present invention:

[0070] like Figure 6 and Figure 7 As shown, the difference from Example 1 is that in Example 1, the distance L1 between the stopping cantilever and the wire pressing barrel is smaller than the length L2 of the wire pressing screw, and the wire pressing screw always maintains threaded engagement with the wire pressing barrel. Although it can prevent the wire pressing screw from loosening, there is also a hidden danger: when the wire pressing screw retreats to stop with the stopping cantilever, the wire pressing screw is still threadedly engaged with the wire pressing barrel. After the operator continues to apply force, the wire pressing screw will continue to retreat, and there is a risk of damaging the stopping cantilever.

[0071] In this embodiment, the distance between the stopping cantilever 304 and the wire pressing barrel 302 is greater than the length of the wire pressing screw 303. When the wire pressing screw 303 is engaged with the stopping cantilever 304, the wire pressing screw 303 and the wire pressing barrel 302 are separated. At this time, if force is continued to be applied to the wire pressing screw 303, the wire pressing screw 303 will not continue to retreat, thus preventing the stopping cantilever 304 from being damaged by the force. However, there is also a problem that the wire pressing screw 303 is easy to swing out sideways from the demoulding notch and be lost. In order to prevent this from happening, Figure 7 As shown, a lateral rib 305 is integrally molded on the insulator 301. The lateral rib 305 is located on the side wall of the demolding notch facing the wire barrel 302. When in use, the lateral rib 305 can stop the wire barrel 303 along the radial direction of the wire barrel 303 and cooperate with the blocking cantilever 304 to limit the wire barrel 303, preventing the wire barrel 303 from swinging to one side and out of the through-channel. In this embodiment, after the lateral rib 305 is integrally molded, the demolding notch becomes smaller, but the mold core can still be removed from this location during demolding.

[0072] The lateral ribs 305 in this embodiment are integrally cast on the insulator 301 . In other embodiments, the lateral ribs can also be installed on the insulator in a separate fixed manner, specifically, by bonding or the like.

[0073] In this embodiment, the lateral rib 305 forms a radial stop portion that stops the wire pressing screw 303 in the side direction.

[0074] Specific embodiment 3 of the connector of the present invention:

[0075] like Figure 8 and Figure 9 As shown, the difference from Example 1 is that in Example 1, the distance L1 between the stopping cantilever and the wire pressing barrel is less than the length L2 of the wire pressing screw, and the wire pressing screw always maintains threaded engagement with the wire pressing barrel. Although it can prevent the wire pressing screw from loosening, there is also a hidden danger: when the wire pressing screw retreats to stop with the stopping cantilever, the wire pressing screw is still threadedly engaged with the wire pressing barrel. After the operator continues to apply force, the wire pressing screw will continue to retreat, and there is a risk of damaging the stopping cantilever.

[0076] In the embodiment, the outer periphery of the crimping screw 402 is not provided with threads throughout, and specifically, the crimping screw 402 comprises a threaded segment 4021 and a smooth rod segment 4022, and the smooth rod segment 4022 is located on the side of the threaded segment 4021 facing the crimping cylinder 404. The distance between the stopper cantilever 403 and the crimping cylinder 404 is less than the length of the crimping screw 402 and greater than the length of the threaded segment 4021. When the crimping screw 402 is withdrawn from the crimping cylinder 404, the threaded segment 4021 is separated from the threaded hole in the crimping cylinder 404 when the crimping screw 402 is stopped by the stopper cantilever 403, but the smooth rod segment 4022 is still located in the threaded hole of the crimping cylinder 404, and the stopper cantilever 403 can prevent the crimping screw 402 from swinging to one side by the stopper cooperation between the smooth rod segment 4022 and the hole wall 405 of the threaded hole.

[0077] In the embodiment, the structure of the insulator 401 is the same as that in Embodiment 1, and will not be described here.

[0078] By providing the smooth rod segment 4022 on the crimping screw 402, on the one hand, the crimping screw 402 can be prevented from swinging to one side, and on the other hand, the crimping screw 402 can also be prevented from continuing to thicken and damaging the stopper cantilever 403.

[0079] In the embodiment, the inner wall surface of the threaded hole opening in the crimping cylinder forms a radial stopper part cooperating with the smooth rod segment 4022.

[0080] It should be noted that the concept of the embodiment is that, by cooperating the crimping screw with the threaded hole in the crimping cylinder, the crimping screw can be prevented from damaging the stopper cantilever and from being separated to one side. Based on the concept, the following mode can also be adopted: the threads are arranged throughout the outer side of the crimping screw, the threaded hole in the crimping cylinder comprises two parts, one part is an inner threaded segment close to the center of the crimping cylinder, and the other part is a smooth hole segment close to the stopper cantilever. The distance L1 between the stopper cantilever and the crimping cylinder is less than the length L2 of the crimping screw, and when the crimping screw is withdrawn to the position of stopper cooperation with the stopper cantilever, the crimping screw is separated from the inner threaded segment and corresponds to the smooth hole segment, and can be cooperated with the smooth hole segment to prevent lateral separation.

[0081] Specific embodiment 4 of the connector of the application:

[0082] As shown in Figure 10 and Figure 11 The embodiment is actually the sum of Embodiment 2 and Embodiment 3, the insulator 501 is provided with a lateral stopper 504, the crimping screw 502 comprises a threaded segment 5021 and a smooth rod segment 5022, the stopper cantilever 505 cooperates with the crimping screw 502 by stopper cooperation, and the lateral stopper 504 cooperates with the threaded segment 5021 by stopper cooperation, the smooth rod segment 5022 cooperates with the hole wall 506 of the threaded hole in the crimping cylinder 503 by stopper cooperation to prevent the crimping screw 502 from swinging laterally and separating.

[0083] In this embodiment, the threaded hole wall 506 and the lateral rib 504 of the threaded hole together form a radial stop portion.

[0084] Specific embodiment 5 of the connector of the present invention:

[0085] like Figures 12 to 14 As shown, this embodiment is a further optimized solution of embodiment 3. A retaining wall 604 is provided on the cantilever 605 in the insulator 601. The retaining wall 604 extends between the two wire-pressing screws 603. A guide chamfer 6041 is provided on the side of the retaining wall 604 facing the wire-pressing barrel 602. The purpose of providing the retaining wall 604 in this embodiment is to prevent the presence of a retaining wall when in use. Figure 13 In the usage scenario, one of the crimping screws 603 is screwed into the crimping barrel 602, leaving a cavity in the insulator 601, while the other crimping screw 603 is not screwed into the crimping barrel 601. At this time, the retaining wall 604 can prevent the crimping screw 603 that is not screwed into the crimping barrel 601 from falling into the cavity. The purpose of providing the guide chamfer 6041 is to eliminate the interference between the end face of the crimping screw 603 and the retaining wall 604 when the crimping screw 603 is screwed out due to slight shaking due to the fitting clearance between the crimping screw 603 and the threaded hole in the crimping barrel 602, thereby guiding the screwing out of the crimping screw 603.

[0086] Of course, it should be noted that the provision of the retaining wall 604 in this embodiment is not only applicable to the situation in Example 3, but also applicable to the usage scenarios in Examples 2 and 4.

[0087] In other embodiments, if the purpose is only to prevent two adjacent wire-pressing screws from falling over each other, the guide chamfer can be eliminated, and the extension length of the retaining wall can be changed according to actual conditions.

[0088] Specific embodiment 6 of the connector of the present invention:

[0089] In the above embodiments, two adjacent wire-pressing screws share a common axial stop portion. In this embodiment, each wire-pressing screw may correspond to its own axial stop portion.

[0090] Specific embodiment 7 of the connector of the present invention:

[0091] In Example 5, each crimping screw shares a through passage, and a retaining wall is provided to prevent them from tilting relative to each other. In this embodiment, each crimping screw has a separate through passage, and each through passage is independent of each other. In this case, a retaining wall is not required.

[0092] Specific embodiment 8 of the connector of the present invention:

[0093] In Example 1, the process opening on the insulator is a demoulding notch. In this embodiment, the insulator is a machined part, and the process opening here is for a tool to be inserted.

[0094] Specific embodiment 9 of the connector of the present application:

[0095] In the embodiment 1, the through channel is provided with a process opening on one side of the insulator, so that the axial stop portion on the insulator stops the cantilever. In this embodiment, the through channel is a closed structure without process opening on the insulator, and the axial stop portion is a lintel integrally formed on the insulator, both ends of which are located on the insulator.

[0096] Specific embodiment 10 of the connector of the present application:

[0097] In the above embodiments, two wire pressing screws are arranged on the same side of the wire pressing cylinder. In this embodiment, the number of wire pressing screws on the same side can be increased or decreased according to actual conditions, which can be one, three or more.

[0098] Specific embodiment 11 of the connector of the present application:

[0099] In the above embodiments, the through hole of the wire pressing cylinder is a threaded hole, and the internal thread section is formed on the threaded hole, and the inner wall of the through channel is smooth. In this embodiment, the through hole of the wire pressing cylinder is a smooth hole, and a thread is formed on the inner wall of the through channel, so that the internal thread section is formed on the through channel.
