Description

Technical Field

[0001] The utility model relates to the technical field of wire fixing, in particular to a wire fixer for a circuit board. Background Art

[0002] With the rapid development of science and technology, electrical products have more and more functions, and with them come more and more problems with the cables of electrical products. Some of these cables are distributed outside the electrical products (such as power cables, video cables, network cables, and audio cables), and some are distributed inside the electrical products (such as power cables and signal cables inside computers, etc.). If the numerous cables are not sorted and fixed, they are likely to appear messy. The large number of cables distributed inside the electrical products may also cause insufficient space inside the product due to the stacking of cables, affecting the heat dissipation of heating components or the installation of other components.

[0003] In order to solve the above problems, the industry has developed some wire holders for arranging wires. For example, a Chinese patent with a publication number of CN217882641U discloses a wire holder, and a form of the bottom fixing member of the wire holder is: including two C-shaped claws and an elastic claw 2 arranged between the two C-shaped claws. When it is necessary to install, the elastic claw 2 needs to be inserted into the mounting hole of the plate, and then the two C-shaped claws are clamped on the column arranged on the plate. This kind of wire holder requires a column to be provided on the plate. For a printed circuit board without a column thereon, the above wire holder is not suitable for arranging wires on the circuit board. To take a step back, even if a column is provided on the circuit board, when the above wire holder is installed on the circuit board and needs to be disassembled for maintenance, it is difficult to disassemble the wire holder from the circuit board because the elastic claw 2 and the C-shaped claw are densely arranged and the elastic claw 2 and the C-shaped claw are tightly connected to other components. In view of this, those skilled in the art continue to seek wire holders that can be stably connected and conveniently disassembled on the circuit board. Utility Model Content

[0004] In order to overcome the defects in the prior art, an embodiment of the utility model provides a wire holder for a circuit board, which can reduce the number of claws while ensuring the stability of the connection between the wire holder and the circuit board, thereby improving the convenience of disassembly and assembly of the wire holder.

[0005] The embodiment of the present application discloses: a wire fixer for a circuit board, comprising a bottom wall, a first side wall, and a second side wall which together form a receiving cavity for accommodating the wires, the first side wall and the second side wall are respectively connected to the two ends of the bottom wall, a clamping groove is provided at one end of the first side wall away from the bottom wall, a cover plate is connected to one end of the second side wall away from the bottom wall via a bending portion, a hook is provided at one end of the cover plate away from the second side wall for engaging with the clamping groove, two elastic claws and at least one supporting portion are provided on the side of the bottom wall away from the receiving cavity, and the supporting portion is located between the two elastic claws.

[0006] Specifically, a positioning column is provided on the wall surface of the support portion away from the bottom wall.

[0007] Specifically, at least one flesh-reducing hole is provided on the support portion.

[0008] Specifically, the length of the bottom wall is between 40 and 80 mm, and the two elastic claws are arranged at two ends of the bottom wall.

[0009] Specifically, a first reinforcing rib is provided between the first side wall and the bottom wall, and a second reinforcing rib is provided between the second side wall and the bottom wall.

[0010] Specifically, an elastic abutment portion is provided on a side of the elastic claw away from the supporting portion, and the elastic abutment portion is used to abut against the circuit board when the elastic claw penetrates into the positioning hole of the circuit board.

[0011] The utility model has at least the following beneficial effects: the wire holder of the present invention reduces the number of elastic claws while ensuring the stability of the connection between the wire holder and the circuit board by providing a support portion for abutting against the circuit board between the two elastic claws, thereby improving the convenience of disassembly and assembly of the wire holder; in addition, the wire holder of the present invention has very low requirements on the installation structure of the circuit board, and only needs to provide a mounting hole on the circuit board; furthermore, thanks to the structure of the present invention, the length of the bottom wall can be set to be longer to be suitable for storing larger wires, and the longer the length of the bottom wall, the more obvious the advantages of the present structure.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "fixed", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood by specific circumstances.

[0019] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include the first feature being in direct contact with the second feature, or may include the first feature being in contact with the second feature through another feature between them instead of being in direct contact. Moreover, a first feature being "above", "below" and "above" a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes the first feature being below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0020] In the description of this embodiment, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present application.

[0021] In addition, the terms "first", "second", etc. are only used to distinguish in description and have no special meaning.

[0022] like Figure 1 As shown, the wire holder for circuit boards of this embodiment mainly includes a bottom wall 1, a first side wall 2 arranged at one end of the bottom wall 1, and a second side wall 3 arranged at the other end of the bottom wall 1. The bottom wall 1, the first side wall 2, and the second side wall 3 together form a receiving chamber for accommodating (accommodating) wires. A slot 21 is provided at one end of the first side wall 2 away from the bottom wall 1, and a cover plate 5 is connected to one end of the second side wall 3 away from the bottom wall 1 through a bending portion 4. The cover plate 5 can rotate relative to the bottom wall 1 with the bending portion 4 as the origin. A hook 51 is provided at one end of the cover plate 5 away from the second side wall 3. The hook 51 is used to engage with the slot 21 on the first side wall 2. When the hook 51 and the slot 21 are engaged, the wires can be bound in the receiving chamber. The hook 51 and the slot 21 are detachably connected so that the wire holder can be reused. Two elastic claws 6 are provided on the side of the bottom wall 1 away from the accommodating cavity. The two elastic claws 6 are distributed at both ends of the bottom wall 1 and are used to be inserted into the mounting holes on the circuit board to achieve the installation of the wire holder. A support portion 7 is also provided on the side of the bottom wall 1 away from the accommodating cavity. The support portion 7 is located between the two elastic claws 6. When the two elastic claws 6 are inserted into the mounting holes on the circuit board, the support portion 7 is used to abut against the circuit board to support the bottom wall 1, so as to prevent the bottom wall 1 from deforming downward (circuit board) due to the large number and weight of wires in the accommodating cavity (in serious cases, it may also rub against components on the circuit board).

[0023] like Figure 1 As shown, the support portion 7 of this embodiment is provided with a positioning column 8 on its wall surface facing away from the bottom wall 1 (it can also be said to be on the bottom surface of the support portion 7), and the positioning column 8 is used to penetrate into the positioning hole on the circuit board. The solution of the positioning column 8 cooperating with the positioning hole can assist in the installation of the wire fixture and improve the convenience of installation. Furthermore, in order to improve the convenience of the positioning column 8 penetrating into the positioning hole or the positioning column 8 being pulled out of the positioning hole, at least one meat-reducing hole 71 is provided on the support portion 7 to reduce the thickness of part of the support portion 7. Specifically, when installing or disassembling the wire fixture, the corresponding part of the bottom wall 1 and the support portion 7 can be pressed by hand to press the positioning column 8 into the positioning hole or pull it out of the positioning hole. The support portion 7 provided with the meat-reducing hole 71 is more likely to bend and deform under the pressure of the finger, thereby facilitating the insertion and removal of the positioning hole.

[0024] like Figure 1 As shown, each elastic claw 6 may also be provided with an elastic abutment portion 61 on one side away from the support portion 7, and the elastic abutment portion 61 may be used to abut against the circuit board when the elastic claw 6 is inserted into the positioning hole of the circuit board. The solution of the elastic abutment portion 61 abutting against the circuit board can prevent the wire holder from shaking relative to the circuit board.

[0025] Combination Figure 1 and Figure 2 As shown, in this embodiment, a first reinforcing rib 91 is further provided between the first side wall 2 and the bottom wall 1 , and a second reinforcing rib 92 is further provided between the second side wall 3 and the bottom wall 1 , which is beneficial to improving the overall strength of the wire holder.

[0026] The length of the bottom wall 1 of this embodiment is between 40 and 80 mm, so the wire holder of this embodiment is suitable for storing larger wires (such as flat cables). Two elastic claws 6 are disposed at both ends of the bottom wall 1 .

[0027] In summary, the wire holder for a circuit board of this embodiment has the following advantages: the wire holder of this scheme reduces the number of elastic claws 6 while ensuring the stability of the connection between the wire holder and the circuit board by setting a support portion 7 for abutting against the circuit board between the two elastic claws 6, thereby improving the convenience of disassembly and assembly of the wire holder; thanks to the structure of this scheme, the length of the bottom wall 1 can be set to be longer to be suitable for the storage of larger wires. The longer the length of the bottom wall 1 is, the more obvious the advantages of this structure are.

[0028] The present invention uses specific embodiments to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
