Description

Technical Field

[0001] The utility model relates to the technical field of data cables, and particularly to a waterproof data cable connector. Background Art

[0002] During the use of data cables, in order to improve the safety of data cable use, a waterproof mechanism is usually provided at the joints at both ends thereof to prevent the joints from coming into contact with moisture. Most of the existing waterproof mechanisms for joints still adopt a relatively traditional cover structure. Such a cover structure mainly includes a cover body fixedly connected to the joint and a cover piece connected to the cover body. By the mutual insertion of the cover piece and the cover body, the effect of sealing and waterproofing the joint is achieved. However, during the use of such a cover structure, it needs to be independently provided at the two joints, so that when sealing the two joints, independent operations are required, which is obviously inconvenient. For this reason, we propose a waterproof data cable connector. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a waterproof data cable connector to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A waterproof data cable connector includes a data cable harness and a sealing sleeve. The sealing sleeve is movably sleeved outside the data cable harness. First connectors and second connectors are fixedly installed at the two outer ends of the data cable harness. The first connector includes a first connection seat fixedly connected between it and the data cable harness. The second connector includes a second connection seat fixedly connected between it and the data cable harness. One side of the outer wall surface of the second connection seat is mutually inserted with the inner wall of the sealing sleeve. The outer peripheral radius of the first connection seat is equal to the outer peripheral radius of the sealing sleeve, and the mutually contacting end surfaces of the first connection seat and the sealing sleeve are mutually inserted. A threaded ring is provided outside the first connection seat and is threadedly connected to the outer peripheries of the first connection seat and the sealing sleeve.

[0005] Preferably, a plurality of positioning jacks are opened at the periphery of one side end surface of the first connection seat close to the first connector. A positioning plug rod is fixedly installed on one side of the outer wall surface of the sealing sleeve. The positioning plug rod is mutually inserted with the positioning jacks.

[0006] Preferably, a first positioning slot and a second positioning block are respectively opened and fixedly installed on the inner and outer wall surfaces on one side of the sealing sleeve away from the positioning plug rod. A first positioning block is fixedly installed on one side of the second connection seat close to the data cable harness. The first positioning block is mutually inserted with the first positioning slot. A second positioning slot is fixedly installed on one side of the first connection seat close to the data cable harness. The second positioning block is mutually inserted with the second positioning slot.

[0007] Preferably, the second connection seat is arranged inside the sealing sleeve, and a through hole is formed in the second positioning plug, and the data line harness is inserted and installed in the through hole.

[0008] Preferably, a fixing seat is fixedly installed in the middle of the outer periphery of the sealing sleeve, and positioning snap rings are sleeved on both sides of the outer periphery of the sealing sleeve, and the two positioning snap rings are symmetrically distributed on both sides of the fixing seat.

[0009] Preferably, a plurality of springs respectively fixedly connected to both sides of the fixing seat are fixedly installed on the opposite end faces of the two positioning snap rings on both sides, and telescopic sleeves inserted into each other are fixedly installed between the fixing seat and the two positioning snap rings, and the springs are arranged inside the telescopic sleeves.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] For this waterproof data line connector, a first connection seat and a second connection head are respectively arranged on the outer sides of the two connection heads, and a sealing sleeve is arranged between the two connection seats. When the two connection heads are aligned with each other, through the threaded connection between the threaded ring, the first connection seat and the sealing sleeve, the two first connection heads and the second connection head can be connected and sealed, achieving the waterproof effect, and there is no need for independent operation at the two connection heads, making it more convenient to use.

[0012] For this waterproof data line connector, through the plug-in connection between the first positioning plug and the first positioning slot, when the first connection head and the second connection head are aligned with each other, the two can be connected. Through the plug-in connection between the second positioning plug and the second positioning slot, when the first connection head and the second connection head are disassembled, and through the through hole, the sealing sleeve can be separated from the second connection seat and connected to the first connection seat. Thus, when the second connection head is connected to handheld devices such as mobile phones and palm computers, it can prevent the sealing sleeve from coming into contact with the user's hand and reduce the discomfort during use.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 , the present invention provides a technical solution: a waterproof data cable connector, including a data cable harness 1 and a sealing sleeve 2. The sealing sleeve 2 is movably sleeved outside the data cable harness 1. First connectors 11 and second connectors 12 are fixedly installed at both outer ends of the data cable harness 1. The first connector 11 includes a first connection seat 21 fixedly connected between it and the data cable harness 1. The second connector 12 includes a second connection seat 22 fixedly connected between it and the data cable harness 1. One side of the outer wall surface of the second connection seat 22 is inserted into the inner wall of the sealing sleeve 2. The outer radius of the first connection seat 21 is equal to the outer radius of the sealing sleeve 2, and the mutually contacting end faces of the first connection seat 21 and the sealing sleeve 2 are inserted into each other. A threaded ring 23 is provided on the outer periphery of the first connection seat 21 and is threadedly connected to the outer peripheries of the first connection seat 21 and the sealing sleeve 2.

[0023] Specifically, when the first connector 11 and the second connector 12 are aligned with each other, the sealing sleeve 2 and the first connection seat 21 are mutually attached, and the sealing sleeve 2 and the second connection seat 22 are inserted into each other. Also, since the outer radius of the first connection seat 21 is equal to the outer radius of the sealing sleeve 2, at this time, by rotating the threaded ring 23, through its threaded fit with the first connection seat 21 and the sealing sleeve 2, the first connection seat 21 and the sealing sleeve 2 can be connected to each other, achieving the effects of positioning and waterproof sealing for the first connector 11 and the second connector 12.

[0024] As a further description of the above technical solution: A plurality of positioning jacks 24 are provided on the periphery of the end face of the first connection seat 21 close to the first connection head 11. A positioning plug 241 is fixedly installed on one side of the outer wall surface of the sealing sleeve 2. The positioning plug 241 is inserted into the positioning jack 24. On the inner and outer wall surfaces of the side of the sealing sleeve 2 away from the positioning plug 241, a first positioning slot 251 and a second positioning block 261 are respectively provided and fixedly installed. A first positioning block 25 is fixedly installed on the side of the second connection seat 22 close to the data cable harness 1. The first positioning block 25 is inserted into the first positioning slot 251. A second positioning slot 26 is fixedly installed on the side of the first connection seat 21 close to the data cable harness 1. The second positioning block 261 is inserted into the second positioning slot 26. The second connection seat 22 is arranged in the sealing sleeve 2, and a through hole 27 is provided in the second positioning block 261. The data cable harness 1 is inserted and installed in the through hole 27.

[0025] Specifically, through the insertion fit between the positioning plug 241 and the positioning jack 24 and between the first positioning block 25 and the first positioning slot 251, when the first connection head 11 and the second connection head 12 are aligned with each other and the threaded ring 23 is rotated, relative offset between the first connection head 11 and the second connection head 12 and between the first connection seat 21 and the sealing sleeve 2 can be avoided, ensuring the stability between the structures; through the insertion fit between the second positioning slot 26 and the second positioning block 261, when the sealing sleeve 2 is separated from the second connection seat 22 and connected to the first connection seat 21 and the threaded ring 23 is rotated, relative offset between the first connection seat 21 and the sealing sleeve 2 can be avoided.

[0026] As a further description of the above technical solution: A fixing seat 3 is fixedly installed in the middle of the periphery of the sealing sleeve 2. Positioning snap rings 31 are sleeved on both sides of the periphery of the sealing sleeve 2. The two positioning snap rings 31 are symmetrically distributed on both sides of the fixing seat 3. A plurality of springs 32 respectively fixedly connected to both sides of the fixing seat 3 are fixedly installed on the facing end faces of the two positioning snap rings 31. An insertion telescopic sleeve 33 is fixedly installed between the fixing seat 3 and the two positioning snap rings 31. The spring 32 is arranged in the telescopic sleeve 33.

[0027] Specifically, the positioning snap ring 31 is provided, and the spring 32 is arranged between it and the fixing seat 3, so that after the threaded ring 23 is rotated to position the first connection seat 21 and the sealing sleeve 2, through the fitting effect between the positioning snap ring 31 and the threaded ring 23, the movement of the threaded ring 23 can be restricted, avoiding the threaded ring 23 from moving along the threaded direction at the connection between it and the first connection seat 21 and the sealing sleeve 2, and ensuring the connection effect between the structures.

[0028] Working principle: When splicing the first connector 11 and the second connector 12, align the first connector 11 and the second connector 12 with each other, and then slide the sealing sleeve 2 around the data cable harness 1 so that the first positioning plug 25 is inserted into the first positioning slot 251, and the positioning plug rod 241 is inserted into the positioning hole 24, so that the sealing sleeve 2 can be connected to the first connector seat 21 and the second connector seat 22. Then, rotate the threaded ring 23 around the first connector seat 21. Through the threaded connection between the threaded ring 23, the first connector seat 21 and the sealing sleeve 2, the first connector seat 21 and the sealing sleeve 2 can be connected to each other, achieving the effect of fixing, sealing and waterproofing the first connector 11 and the second connector 12;

[0029] Conversely, rotating the threaded ring 23 in the reverse direction can separate the first connector 11 and the second connector 12 from each other. Then, slide the sealing sleeve 2 to the other side of the data cable harness 1 around the data cable harness 1. By inserting the second positioning plug 261 into the second positioning slot 26, the other side of the sealing sleeve 2 can be inserted into the other side of the first connector seat 21. At this time, the sealing sleeve 2 is separated from the second connector seat 22. Adjust the threaded ring 23 to the other side of the first connector seat 21 through the thread at the connection between the threaded ring 23 and the first connector seat 21, and then, through the threaded connection between the threaded ring 23, the first connector seat 21 and the sealing sleeve 2 again, the first connector seat 21 and the sealing sleeve 2 can be fixed;

[0030] Moreover, during the manual rotation of the threaded ring 23, the threaded ring 23 fits with the positioning snap ring 31 and pushes the positioning snap ring 31 to move towards the fixed seat 3. After loosening the threaded ring 23, under the action of the spring 32 restoring deformation, the threaded ring 23 can be pushed to move outward along the axis of the sealing sleeve 2, which makes the threaded connection between the threaded ring 23, the first connector seat 21 and the sealing sleeve 2 tighter and can prevent the threaded ring 23 from loosening.

[0031] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
