Description

Technical Field

[0001] The present application relates to the technical field of connection structures, and in particular to a wire connector. Background Art

[0002] Guided connections are often used between electrical components and controllers in electrical appliances. This type of connection is relatively flexible. Welding is a commonly used connection method, but hot welding will shorten the length of the metal core of the wire. For line structures with tight wiring, if the wire solder joints fall off, secondary hot welding will be required and the length of the wire may be very limited. Therefore, under normal circumstances, there will be relatively long redundant wires in electrical appliances, and it is difficult to achieve both tight wiring and fault tolerance. Summary of the invention

[0003] The object of the present application is to provide a connector that can tighten a wire without damaging the metal core of the wire.

[0004] To achieve the above objectives, the present application provides a wire connector: comprising a rotating sleeve and a fixed sleeve that are rotatably connected, the rotating sleeve comprising a wire barrel, the inner wall of the wire barrel having a guide strip parallel to the axis, the rotating sleeve being slidably connected to a follower handle through the guide strip, the follower handle being provided with twisted wire holes passing through both end surfaces, the twisted wire holes being at least two, the fixed sleeve comprising a wire insertion barrel, the wire insertion barrel being provided with wire threading holes passing through both end surfaces, the number of the wire threading holes corresponding to the number of the twisted wire holes, for the metal core of the wire to pass through.

[0005] Preferably, the outer surface of one end of the wire bundle barrel facing the fixed sleeve has a coaxial outer rotating ring, and the end of the wire insertion barrel facing the rotating sleeve has a coaxial fixed plate, and the inner wall of the fixed plate is provided with a coaxial inner ring groove, which is suitable for cooperating with the rotating sleeve to form a rotating pair, thereby limiting the freedom of movement of the rotating sleeve relative to the fixed sleeve.

[0006] As a preference, the movably connected limiting block on the fixed plate is suitable for limiting the rotation of the rotating sleeve relative to the fixed sleeve, so as to facilitate the alignment of the follower handle with the through hole structure inside the fixed sleeve.

[0007] Preferably, a sliding groove is provided on the end surface of the fixed plate facing the rotating sleeve, a slot is provided on the outer surface of the cable tie barrel, the limit block includes a slider and a slide plate, the slide plate is suitable for cooperating with the sliding groove to form a sliding pair, and the slider is suitable for plugging and cooperating with the slot, so as to limit the rotation of the rotating sleeve relative to the fixed sleeve.

[0008] As a preference, the upper surface of the sliding block extends outside the fixed plate and is fixedly connected with a push handle to facilitate adjustment of the position and state of the limit block.

[0009] As a preference, the outer side surface of one end of the cable tie reel away from the fixed sleeve has a moving disk, and the outer sides of the moving disk and the fixed disk are provided with friction grooves for increasing the friction force in contact with the hand.

[0010] Preferably, there are two guide bars on the inner wall of the cable spool, and the two guide bars are symmetrical about the axis of the cable spool. The follower handle is provided with guide grooves corresponding to the guide bars, suitable for cooperating with the guide bars to form a sliding pair to limit the movement freedom of the follower handle.

[0011] As a preference, the end surface of the follower handle facing away from the fixed sleeve is fixedly connected with a push rod, and the end of the push rod away from the follower handle is fixedly connected with a plug handle, thereby increasing the contact area with the thumb and reducing the downward pressure.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] (1) By providing a rotating sleeve and a fixed sleeve structure that can rotate relative to each other, and providing a slidable follower handle structure in the rotating sleeve, the guides to be connected can be twisted. During the twisting process, the wires will be gradually tightened, making the arrangement of the wires more compact. During the twisting process, the metal core of the guide will not be damaged and shortened. Therefore, even after multiple connections and disassemblies, the wires will not be shortened. The wires do not need to be reserved too long and have a high fault tolerance rate.

[0014] (2) Since the diameter of the moving disk and the fixed disk is much larger than the diameter of the conductor, it is much more labor-saving than directly twisting the metal core of the guide, especially for the metal core with harder material, the labor-saving effect will be more obvious.

For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0028] like Figure 1-8The wire connector shown in the figure includes a rotating sleeve 1 and a fixed sleeve 2 which are rotatably connected, and the two are matched through opposite ends. Specifically, the rotating sleeve 1 includes a cable barrel 101 with two ends connected, and the outer surface of the cable barrel 101 facing the fixed sleeve 2 has a coaxial outer rotating ring 105, and the outer diameter of the outer rotating ring 105 is slightly larger than the outer diameter of the cable barrel 101. The end of the plug-in barrel 201 facing the rotating sleeve 1 has a coaxial fixed plate 203, and the outer side surface of the fixed plate 203 is provided with a friction groove for increasing the contact between the fixed plate 203 and the hand. The friction force of the wire reel 201 cannot be rotated after holding the fixed plate 203. The inner wall of the fixed plate 203 is provided with a coaxial inner ring groove 205, which is used to cooperate with the rotating sleeve 1 to form a rotating pair, and limit the movement of the rotating sleeve 1 relative to the fixed sleeve 2 along the axis. The outer side surface of the wire reel 101 away from the fixed sleeve 2 has a moving plate 103, and the outer side surface of the moving plate 103 is also provided with a friction groove, which is also used to increase the friction force in contact with the hand. The wire reel 101 can be rotated by holding the moving plate 103, so that the rotating sleeve 1 can rotate relative to the fixed sleeve 2.

[0029] The fixed plate 203 is movably connected to the limiting block 4, which is used to limit the rotation of the rotating sleeve 1 relative to the fixed sleeve 2. Specifically, the fixed plate 203 is provided with a slide groove 204 on the end surface facing the rotating sleeve 1, and the slide groove 204 extends along the radial direction of the fixed plate 203. The outer surface of the cable barrel 101 is provided with a slot 104, and the slot 104 extends along the radial direction of the cable barrel 101. When the slot 104 is aligned with the slide groove 204, the stranding hole 301 is aligned with the threading hole 202. The limiting block 4 includes a slider 401 and a slide plate 402, both of which are The integrated structure has a T-shaped cross-section. Since the slide plate 402 is wider than the slider 401, it is more suitable for cooperating with the slide groove 204 to form a sliding pair, which can effectively prevent the limit block 4 from falling off the fixed plate 203. The slider 401 can be plugged into the slot 104. Due to the blocking effect of the slider 401, the rotating sleeve 1 cannot rotate relative to the fixed sleeve 2. The upper surface of the slider 401 extends to the outside of the fixed plate 203 and is fixedly connected to a push handle 403, which is convenient for moving the entire limit block 4, thereby adjusting the position and state of the limit block 4.

[0030] The inner wall of the cable drum 101 has a guide strip 102 parallel to the axis. There are two guide strips 102 on the inner wall of the cable drum 101, and the two guide strips 102 are symmetrical about the axis of the cable drum 101. The rotating sleeve 1 is slidably connected to the follower handle 3 through the guide strip 102. The follower handle 3 is provided with a guide groove 302 corresponding to the guide strip 102, which is used to cooperate with the guide strip 102 to form a sliding pair. The follower handle 3 cannot rotate relative to the cable drum 101. The end surface of the follower handle 3 facing away from the fixed sleeve 2 is fixedly connected to a push rod 303, which can push the follower handle 3 to change its height in the cable drum 101. The end of the push rod 303 away from the follower handle 3 is fixedly connected to a plug handle 304, which increases the end area of ​​the push rod 303, thereby reducing the pressure of contact with the thumb. The outer wall shape of the plug handle 304 can be set to be the same as the inner wall of the cable drum 101, so that it is in close contact with the inner wall of the cable drum 101, which plays a good shielding role.

[0031] The fixed sleeve 2 includes a wire insertion barrel 201, which is provided with wire threading holes 202 passing through both end surfaces, and the follower handle 3 is provided with twisted wire holes 301 passing through both end surfaces. The metal core of the wire to be connected will pass through the twisted wire holes 301, and the insulating sleeve of the wire will remain in the wire threading holes 202. There are at least two twisted wire holes 301, because connection is required only when there are at least two wires. When there are three twisted wire holes 301, the three wires can be twisted together. The number of wire threading holes 202 corresponds to the number of twisted wire holes 301. When the wire threading holes 202 are aligned with the twisted wire holes 301, the wires can smoothly pass through the wire insertion barrel 201 and enter the wire bundle barrel 101.

[0032] Working principle: In the initial state, the limit block 4 is inserted into the slot 104, the follower handle 3 is against the end face of the fixed sleeve 2, the stranded wire hole 301 is aligned with the threading hole 202, and the exposed end of the metal core of the wire to be connected is inserted into the threading hole 202 until the guiding insulating sleeve is against the end face of the follower handle 3. At this time, the guiding metal core also passes through the stranded wire hole 301. The other wires are installed in the above steps and inserted into place. The limit block 4 can be pushed open to release the locking state of the rotating sleeve 1 relative to the fixed sleeve 2. Hold the fixed disk 203 with one hand and rotate the rotating disk 103 with the other hand. The rotating follower handle 3 will pass through the stranded wire hole 301. The guide metal cores are twisted together. At the same time, the follower handle 3 is pushed by the twisted metal core and gradually slides away from the fixed sleeve 2 until the metal cores of all the wires are out of the twisted wire holes 301. Finally, the plug handle 304 is pressed to allow the follower handle 3 to apply pressure to the twisted metal core, so that it bends and fits the end surface of the fixed sleeve 2 located in the rotating sleeve 1, and the slide groove 204 is aligned with the slot 104 and the limit block 4 is re-locked to complete the connection of the wires. After the wires are connected, they have good conductive contact characteristics, and the twisted structure is not easy to loosen under pressure, and the stability of the connection is also relatively high.
