Description

Technical Field

[0001] This utility model relates to the field of wire storage technology, and specifically provides a wire reel device for wire storage. Background Technology

[0002] Secondary wiring harness connection is a core process in electrical control cabinet assembly, used to connect secondary circuits. This mainly refers to the termination and connection of low-voltage control signal return wiring harnesses (such as PLC I / O lines, sensor lines, relay control lines, communication lines, etc.). This process requires processing the wires to be connected. Guiding treatment includes fitting number tubes and crimping terminals. The number tube is fitted onto one end of the wire and fixed to the wire using a heat-shrink process. Then, the terminal is connected to the end of the wire, and the terminal is used to connect to the terminal block inside the electrical control cabinet.

[0003] The connection of secondary wiring harnesses in electrical cabinets requires a large number of wires to be connected, and each wire needs to be connected to the correct position on the terminal block, resulting in low connection efficiency. Utility Model Content

[0004] This invention provides a wire reel device for storing wires, which solves the problem of low wire insertion efficiency in secondary wire harness splicing.

[0005] The technical solution of this utility model is as follows:

[0006] A wire reel device for storing wires includes a reel body with a plurality of slots. Both ends of each slot penetrate the reel body, and the width of the slot is adapted to the diameter of the wire to be stored. The reel body also has a positioning hole, one end of which penetrates the reel body. The axis of the positioning hole is located within the slot, and the diameter of the positioning hole is greater than the width of the slot. A number tube is provided at the end of the wire, and the diameter of the positioning hole is adapted to the diameter of the number tube. The axial dimension of the positioning hole is less than the thickness of the reel body. The positioning hole forms a step on the sidewall of the slot, and the end of the number tube abuts against the step.

[0007] In this design, the wires can pass through slots, and the number tubes can be inserted into positioning holes. The end of the number tube abuts against a step, allowing for wire positioning. Furthermore, because the number tube is inserted into the positioning hole, it is constrained circumferentially by the hole, preventing it from tilting relative to the end face of the panel and ensuring its verticality. The positioning hole positions the number tube, fixing its orientation because it is located at the end of the wire. During use, the number tubes of each wire can be pre-inserted into the positioning holes, and then the panel can be moved to connect all wires to the terminal block, completing the connection of all wires corresponding to that terminal block in one operation, thus improving the efficiency of terminal block-wire connection.

[0008] To prevent the number tube from becoming misaligned due to an imbalance in the radial forces exerted on it by the positioning hole and the slot, the axis of the positioning hole is spaced at the same distance from the two side walls of the slot.

[0009] In this design, because the axis of the positioning hole is centered within the slot, when the number tube is located in the positioning hole, the axis of the number tube and the axis of the wire are also centered. The outer walls of the number tube and the wire will not squeeze the side walls of the slot or the positioning hole due to axis offset, thus keeping the radial force on the number tube balanced, avoiding tilting due to unbalanced radial force on the number tube, and ensuring smooth movement of the number tube and the wire.

[0010] Preferably, the positioning hole is located at the bottom of the slot.

[0011] In this design, the positioning hole is located at the bottom of the slot, making it easier to insert the number tube. When insertion is needed, the wire is moved into the slot from the opening, then directly moved to the bottom of the slot, and then pulled to move the number tube from the axis of the positioning hole into the slot. Because the positioning hole is located at the bottom, there is no need for the number tube to be aligned with the axis of the positioning hole, facilitating insertion.

[0012] Preferably, each slot has a different number of positioning holes.

[0013] In this solution, depending on the terminal block, the position of each positioning hole corresponds to the position of the terminal block and the terminal connection part. Therefore, the position of the positioning hole can be set according to the specific terminal block, so that the position of the number tube and wire positioned through the positioning hole corresponds to the terminal block.

[0014] Preferably, the distance between each positioning hole and the bottom of the slot is different.

[0015] In this solution, the position of the positioning hole in the slot can be flexibly set according to the different terminal blocks to correspond to different terminal blocks.

[0016] Preferably, the positioning hole forms steps on the two side walls of the slot.

[0017] In this design, both side walls of the slot have steps. After the number tube is inserted into the positioning hole, both sides of the end face of the number tube can abut against the steps. The steps can play a role in axial positioning of the number tube and prevent displacement relative to the disk body during the insertion of the wire.

[0018] The width of the slot is adapted to the diameter of the wire. However, the wire needs to be aligned with the slot position when inserted, which can be inconvenient. Therefore, the width of the slot increases outward along the opening direction of the slot.

[0019] In this design, the wider slot opening eliminates the need for precise alignment when inserting wires, reducing the difficulty of insertion and making wire insertion easier.

[0020] Different terminal blocks are connected to wires at different positions, which requires different wire block devices, resulting in high costs. Therefore, at least two positioning holes are provided in the slot.

[0021] In this solution, at least two positioning holes can be provided in the slot. Positioning holes in different positions can correspond to different terminal blocks, thereby reducing costs by improving versatility.

[0022] Different terminal blocks connect to wires of different thicknesses, requiring different wire reel devices, which results in high costs. Therefore, the diameter of each positioning hole increases outward from the opening direction of the slot.

[0023] In this design, the diameter of each positioning hole increases progressively, which can be used to position number tubes of different diameters to suit different terminal blocks and improve versatility.

[0024] The number tube or wire is scratched when it comes into contact with the opening of the positioning hole or the opening of the slot. To address this, the end of the positioning hole is chamfered, and / or the opening of the slot is rounded.

[0025] In this design, the chamfer prevents the number tube or wire from being cut by the opening of the positioning hole, thus protecting the number tube and wire. Similarly, the rounded corners of the slot opening serve the same purpose.

[0026] The beneficial effects of this utility model are:

[0027] This invention positions the wires and number tubes by setting slots and positioning holes, keeping the number tubes perpendicular to the panel. When the panel is moved, all wires connected to the panel can be accurately connected to the terminal blocks, improving the connection efficiency between the wires and the terminal blocks.

[0028] To more clearly illustrate the technical solution of this utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0030] Figure 2 This is a partial structural diagram of the slot section.

[0033] The technical solution of this utility model will be clearly and completely described in conjunction with the accompanying drawings and through specific embodiments.

[0034] Example 1:

[0035] like Figure 1 As shown in the figure, this embodiment provides a wire reel device for storing wires, including a reel body 1. The reel body 1 has several slots 2, the openings of which extend outwards radially from the reel body 1. The two ends of the slots penetrate the two end faces of the reel body 1, and the slots 2 are used to insert wires. The reel body 1 also has several positioning holes 3. The axis of the positioning holes 3 is located within the slots 2. The diameter of the positioning holes 3 is greater than the width of the slots 2, and the axial length of the positioning holes 3 is less than the thickness of the reel body 1, meaning the length of the positioning holes 3 is less than the length of the slots 2. Because the diameter of the positioning holes 3 is greater than the width of the slots 2, the positioning holes 3 form a step 4 on the side wall of the slots 2. The width of the slots 2 is less than the diameter of the number tube, while the diameter of the positioning holes 3 matches the diameter of the number tube, meaning the number tube can be inserted into the positioning holes 3. However, after the number tube is inserted into the positioning holes 3, the inserted end of the number tube will abut against the step 4. The wall of the positioning holes 3 constrains the number tube, keeping its axis perpendicular to the reel body 1 and preventing the number tube from tilting relative to the reel body 1. After positioning the number tube relative to the panel 1, all wires connected to the panel 1 can be moved by moving the panel 1, ensuring that the ends of the wires are aligned with the terminal blocks to be connected.

[0036] Slot 2 forms a U-shaped opening on the disk body 1, allowing the wire to enter the slot 2 through this opening. Because the diameter of the number tube is larger than the width of the slot 2, when the wire enters the slot 2, the position of the number tube and the slot 2 is offset along the axis of the number tube, allowing the wire to enter the slot 2 through the opening. The number tube is fitted onto the surface of the wire. When the number tube moves with the wire to a position coaxial with the positioning hole 3, it is moved along the axis, allowing the number tube to enter the positioning hole 3.

[0037] like Figure 2As shown, a chamfer 5 is provided at the opening of the positioning hole 3. The chamfer 5 has two functions. The first function is to prevent the opening of the positioning hole 3 from being too sharp and scratching the wire or number tube. The diameter of the positioning hole 3 is matched with the diameter of the number tube. It is mainly used to avoid the number tube being scratched when it is inserted into the positioning hole 3. However, the wire may also come into contact with the opening of the positioning hole, so it may also be scratched by the opening of the positioning hole 3 to a certain extent. The other function of the chamfer 5 is to make it easier for the number tube to enter the positioning hole 3 when it moves along the axial direction.

[0038] The opening of slot 2 can be rounded to a radius of 6. This radius prevents the wires or number tubes from coming into contact with the slot opening and being scratched. Similarly, the radius of 6 at the opening of slot 2 can be replaced with a chamfer.

[0039] The number tube needs to be moved to a position coaxial with the positioning hole 3, and then moved along the axial direction into the positioning hole 3. To facilitate determining the position of the number tube coaxial with the positioning hole 3, the positioning hole 3 can be located at the bottom of the slot 2. If the positioning hole 3 is located at the bottom of the slot, it is only necessary to move the wire to the bottom of the slot to move the number tube axially, making it simpler to align the number tube with the positioning hole 3, reducing the difficulty of operation and improving the efficiency of operation. That is to say, the positioning hole 3 is preferably set at the bottom of the slot 2, as this design makes it easier to insert the number tube into the positioning hole 3. Therefore, setting the positioning hole 3 in other positions of the slot 2, although it may cause inconvenience in operation, can still serve the purpose of positioning the number tube. Therefore, the positional relationship between the positioning hole 3 and the slot 2 at each slot 2 of the disk body 1 may be different. For example, the positioning hole 3 corresponding to one slot 2 may be located at the bottom of the slot 2; while the distance between the positioning hole 3 corresponding to another slot 2 and the bottom of the slot 2 may be greater than the radius of the positioning hole 3, that is, after the number tube is inserted into the positioning hole 3, there is a gap between the number tube and the bottom of the slot 2.

[0040] Slot 2 is a U-shaped slot. Preferably, slot 2 has a symmetrical cross-section, such as a rectangular or trapezoidal cross-section, meaning slot 2 is a rectangular or trapezoidal slot. In this case, the axis of the positioning hole 3 is equidistant from the two side walls of slot 2. The positioning hole 3 simultaneously forms steps 4 on both sides of slot 2, and the steps 4 on both sides of slot 2 have the same shape. When the number tube is inserted into the positioning hole 3, the axes of the wire in slot 2 and the number tube in positioning hole 3 remain coaxial. The force exerted by positioning hole 3 on the number tube maintains balance, preventing misalignment between the wire in slot 2 and the number tube in positioning hole 3, thus ensuring the number tube remains perpendicular to disk 1.

[0041] The shape of the disc body 1 is adapted to the corresponding terminal block. The position of the positioning hole 3 needs to be aligned with the connection position on the terminal block in order to move the disc body 1 so that the ends of all wires can be inserted into the corresponding positions on the terminal block. Depending on the shape of the terminal block, the shape of the disc body 1 can be circular, elliptical, regular polygonal, etc.

[0042] Slot 2 is arranged along the circumference of disk body 1, and each wire enters slot 2 from the opening of slot 2 on the circumference of disk body 1. After the number tube enters the positioning hole 3, it can prevent the wire from continuing to move in slot 2.

[0043] Example 2:

[0044] like Figure 2 As shown, this embodiment 2 provides a wire reel device for storing wires. Unlike embodiment 1, the slot 2 in this embodiment 2 can be provided with two or more positioning holes 3.

[0045] Terminal blocks in electrical cabinets may come in different specifications. With different specifications of terminal blocks, the connection positions of each wire may also be different, and the diameter of the wires corresponding to the terminal blocks may also be different. In this case, designing a separate wire reel device for the terminal blocks would require additional costs, resulting in high costs.

[0046] To address this issue, at least two positioning holes 3 can be provided within the slot 2 of this embodiment. In practical use, depending on the specifications of the terminal block, the wire number tube can be inserted into different positioning holes 3 to achieve the effect of the wire position corresponding to the terminal block. Under this implementation, a single wire reel device can be applied to different terminal blocks, improving versatility and reducing costs.

[0047] When a slot 2 is provided with at least two positioning holes 3, the diameter of each positioning hole 3 can be the same, which is suitable for situations where the wire positions are different; or, the diameter of each positioning hole 3 can also be different, which is suitable for situations where the wire positions and diameters are different.

[0048] With different diameters for the positioning holes 3, the diameters of the positioning holes 3 increase outwards along the opening direction of the slot 2. Furthermore, since the diameter of the wire corresponds to the diameter of the number tube, the larger the diameter of the wire, the larger the diameter of the number tube. Therefore, when the diameters of the positioning holes 3 are different, the corresponding diameters of the number tubes are also different; the larger the diameter of the positioning hole 3, the larger the diameter of the corresponding number tube. The larger the diameter of the number tube, the larger the diameter of the corresponding wire, and the larger the diameter of the wire, the larger the width of the corresponding slot 2 should be. Therefore, with different diameters for the positioning holes 3, the width of the slot 2 increases outwards along the opening direction of the slot 2, meaning the cross-sectional shape of the slot 2 is trapezoidal, used to accommodate wires of different diameters.
