Description

Technical Field

[0001] This utility model relates to the field of wire connectors, and in particular to a waterproof cable connector. Background Technology

[0002] Waterproof cable joints, as key connection components in power, communication, and industrial equipment, are widely used in outdoor facilities, underwater equipment, and complex working environments. Their core function is to protect cable connections from external factors such as moisture and dust, ensuring the stability and safety of electrical connections. Traditional waterproof cable joints mostly use threaded tightening and sealing ring compression to achieve sealing and fixation. While this design can meet basic waterproofing requirements, there is still room for improvement in terms of installation efficiency, locking reliability, and ease of maintenance.

[0003] Currently, traditional cable waterproof connectors rely on manual tightening of threads or pressing of sealing rings. Installation is time-consuming and labor-intensive, and disassembly requires loosening the threads in the opposite direction or using special tools. The operation is cumbersome and can easily damage the sealing structure. Especially in emergency maintenance scenarios, the traditional structure significantly prolongs equipment downtime and increases maintenance costs. Utility Model Content

[0024] This utility model proposes a waterproof cable connector.

[0025] like Figure 1As shown in one embodiment of this utility model, a waterproof cable connector includes a first connector 1 and a second connector 2 fixedly connected to the first connector 1. The first connector 1 is fitted with a fixing cap 3, the shape of which is not limited. The fixing cap 3 is movably connected to the first connector 1. An elastic fixing member 11 for fixing the cable is provided inside the first connector 1. When the cable is inserted into the first connector 1, the elastic fixing member 11 automatically fixes the cable. The fixing cap 3 is provided with a release part 31 for releasing the cable. The release part 31 is inserted into the first connector 1 and abuts against the elastic fixing member 11. When it is necessary to disassemble the cable... Pushing the release part 31 causes the elastic fixing member 11 to release the cable, and then the circuit is pulled out to achieve quick disassembly. A guide groove 32 is provided on the inner side of the fixing cap 3, and a protrusion 12 is provided on the outer side of the first connector 1. When the fixing cap 3 is fitted onto the first connector 1, the protrusion 12 is embedded in the guide groove 32. The fixing cap 3 is provided with a snap-fit ​​groove 33, and the first connector 1 is also provided with an elastic snap-fit ​​member 13. When the fixing cap 3 is pushed to the preset position along the guide groove 32, the snap-fit ​​member 13 and the snap-fit ​​groove 33 engage with each other to fix the fixing cap 3, so as to prevent the elastic fixing member 11 from releasing the cable during the operation, which would cause the cable to loosen or fall off.

[0026] The elastic fastener 11 can be an elastic rubber ring, or the cable can be fixed by the cooperation of the spring 132 and the fixing block. The shape of the release part 31 is preferably consistent with the inside of the first connector 1, and they are fitted together and slidably connected.

[0027] This embodiment uses an elastic fixing member 11 inside the first connector 1 to quickly fix the cable, and releases the cable by the release part 31 acting on the elastic fixing member 11, thus achieving rapid cable removal. When a circuit is inserted into the first connector 1, the elastic fixing member 11 locks the cable, and at the same time pushes the fixing cap 3 to move along the guide groove 32 to a preset position, so that the elastic snap-fit ​​member 13 quickly snaps into the snap-fit ​​groove 33 to complete the fixation. When it is necessary to remove the cable, the elastic snap-fit ​​member 13 is controlled to release the snap-fit, and the fixing cap 3 is pushed to the preset position so that the release part 31 acts on the elastic fixing member 11 to release the cable for pulling out, thereby achieving rapid installation and removal of the cable and improving efficiency.

[0028] Furthermore, the outer side of the first connector 1 is provided with an annular protrusion 12, and the inner side of the fixing cap 3 is provided with an L-shaped groove. During installation, the protrusion 12 is inserted along the vertical section of the groove, and the fixing cap 3 is rotated to slide along the horizontal section to complete the mechanical locking. The front end of the fixing cap 3 is provided with a snap-fit ​​groove 33, and the side wall of the first connector 1 has an opening for the built-in elastic snap-fit ​​element 13, which includes a spring 132 and a snap-fit ​​block 131. When the fixing cap 3 is rotated into place, the snap-fit ​​block 131 is embedded into the snap-fit ​​groove 33 under the action of the spring 132, forming a double lock. The tubular release part 31 inside the fixing cap 3 is inserted into the first connector 1, pushing the elastic piece 14 of the elastic fixing element 11 to open, realizing the rapid release of the cable.

[0029] Preferably, such as Figure 2 As shown, the elastic fastener 11 includes multiple elastic pieces 14. The elastic pieces 14 are evenly distributed on the inner periphery of the first connector 1 and are obliquely inserted towards the second connector 2. The release part 31 abuts against each elastic piece 14 to form a funnel-like structure, which gives it a one-way valve function. After the cable is inserted into the first connector 1, it can pass smoothly through the elastic piece 14. When the cable is pulled out backward, the elastic piece 14 will hold the cable in place, preventing it from being pulled out, thereby achieving the one-way fixing function.

[0030] Furthermore, the elastic fastener 11 consists of eight stainless steel elastic plates 14, inclined at a 25° angle toward the second connector 2. The ends of the elastic plates 14 are provided with anti-slip teeth. When the cable is inserted, the elastic plates 14 generate radial clamping force due to the inclined angle. When the cable is pulled out, the elastic plates 14 insert into the relatively protruding or soft parts of the cable to prevent it from being pulled out. The tubular front end of the release part 31 pushes the root of the elastic plates 14, causing them to open outward by 3mm, releasing the clamping of the cable and facilitating cable removal.

[0031] Preferably, the release part 31 is a tubular cylinder inserted into the first connector 1. One end of the tubular cylinder abuts against the elastic sheet 14, and the other end is fixedly connected to the fixing cap 3. The tubular cylinder has a similar internal shape to the first connector 1 and can fit together with it, which facilitates cable insertion.

[0032] Furthermore, the release part 31 is a stainless steel tube with a 30° chamfer at the front end. When the fixing cap 3 is rotated into place, the chamfer contacts the root of the elastic sheet 14, pushing the elastic sheet 14 to open. The end of the tube is fixed to the inner wall of the fixing cap 3 by laser welding.

[0033] Preferably, such as Figure 3 As shown, the elastic snap-fit ​​component 13 includes a snap-fit ​​block 131 and a spring 132. The first connector 1 is provided with an installation groove. One end of the spring 132 is fixedly connected to the bottom of the installation groove, and the other end of the spring 132 is fixedly connected to the snap-fit ​​block 131. When the fixing cap 3 is pushed to the preset position, the fixing block is quickly ejected by the spring 132 and inserted into the snap-fit ​​groove 33 to fix the fixing cap 3.

[0034] Preferably, the snap-fit ​​groove 33 connects the inner and outer sides of the fixing cap 3, making it convenient to use a tool to press the fixing block to release the locking of the fixing cap 3.

[0035] Furthermore, the snap-fit ​​groove 33 is a rectangular groove that runs through the inside and outside of the fixing cap 3, and an EPDM rubber sealing ring 34 is provided at the edge of the groove. When the snap-fit ​​block 131 is inserted, the sealing ring 34 is deformed under pressure to fill the gap.

[0036] Furthermore, the fixing cap 3 is provided with an elastic push switch at the snap-fit ​​groove 33. The elastic push switch abuts against the snap-fit ​​block 131 to facilitate the release of the snap-fit ​​state of the snap-fit ​​block 131, so that the fixing cap 3 can move.

[0037] Preferably, the end of the snap-fit ​​block 131 away from the spring 132 is provided with an arc-shaped guide portion 133. The arc-shaped guide portion 133 is smoothly arranged. When the snap-fit ​​state of the snap-fit ​​block 131 is released, the arc-shaped guide portion 133 causes the snap-fit ​​block 131 to retract when the fixing cap 3 is moved, which facilitates the movement of the fixing cap 3.

[0038] Furthermore, the front end of the snap-fit ​​block 131 is machined into an arc-shaped guide surface, which is coated with polytetrafluoroethylene. When the fixing cap 3 rotates, the guide surface contacts the edge of the snap-fit ​​groove 33, and the coefficient of friction is ≤0.1.

[0039] Preferably, the guide groove 32 is an L-shaped groove, and the snap-fit ​​groove 33 is provided at one end of the L-shaped groove. When the fixing cap 3 is pushed to the preset position along the L-shaped groove, the snap-fit ​​member 13 and the snap-fit ​​groove 33 are engaged with each other.

[0040] Preferably, such as Figure 4 As shown, a sealing ring is fitted on the inner wall of the release part 31. The sealing ring is funnel-shaped, with the smaller end of the sealing ring opening facing the second connector 2. When the cable is inserted, the smaller end of the sealing ring opening is squeezed to form a seal.

[0041] Furthermore, a double-lip silicone sealing ring is provided on the inner wall of the release part 31. The lips are flared out in a trumpet shape, with the inner diameter gradually changing from Φ8mm to Φ15mm. When a Φ10mm cable passes through, the lips create a bidirectional seal; the outer lip prevents external liquid from entering, while the inner lip prevents internal pressure leakage. The sealing ring is fixed inside the release part 31 by an interference fit.

[0042] Specifically, the working principle and usage process of this utility model are as follows: The cable is quickly fixed by setting an elastic fixing member 11 inside the first connector 1, and the cable is released by the release part 31 acting on the elastic fixing member 11, thus achieving rapid cable removal. When a circuit is inserted into the first connector 1, the elastic fixing member 11 locks the cable, and simultaneously pushes the fixing cap 3 along the guide groove 32 to a preset position, so that the elastic snap-fit ​​member 13 quickly snaps into the snap-fit ​​groove 33, completing the fixation. When the cable needs to be removed, the elastic snap-fit ​​member 13 is controlled to release the snap-fit, and the fixing cap 3 is pushed to a preset position so that the release part 31 acts on the elastic fixing member 11 to release the cable for pull-out, thereby achieving rapid cable installation and removal and improving efficiency.

[0043] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
