[0025] Please refer to Figure 1-5 As shown, the utility model provides a power cord fastening device 100 , comprising a mounting seat 1 and a wire pressing plate 2 engaged with the mounting seat 1 .
[0026] The mounting base 1 includes a mounting plate 11, two protective walls 12 protruding and extending from the upper surface of the mounting plate 11 and arranged opposite to each other, two force-bearing walls 13 and a clamping wall 14 arranged opposite to each other, a horizontal bar 15 extending from the two force-bearing walls 13 in directions approaching each other, a wire groove 16 formed by the top sides of the two protective walls 12 being recessed downward, and a first wire pressing tooth 17 protruding and extending from the upper surface of the mounting plate 11.
[0027] The protective wall 12 and the stress-bearing wall 13 together enclose a rectangular receiving space, and the clamping wall 14 divides the receiving space into a first wire-accommodating space 101 and a second wire-accommodating space 102 for accommodating the power cord 10. In this embodiment, only the first wire-accommodating space 101 is actually used to accommodate the power cord 10, and the second wire-accommodating space 102 is a structural setting. Both wire grooves 16 are connected to the first wire-accommodating space 101, and the first wire-pressing tooth 17 is located in the first wire-accommodating space 101 and is separated from the clamping wall 14 to form a limiting groove 18.
[0028] The wire pressing plate 2 includes a wire pressing plate body 21 arranged opposite to the mounting plate 11, two side positioning plates 22 bent downwardly and extended from opposite sides of the wire pressing plate 21, two buckle walls 23 bent and extended in directions away from each other from one end of the two side positioning plates 22 away from the wire pressing plate body 21, and a limiting wall 24 formed by extending downward from the wire pressing plate body 21.
[0029] The outer side of the connection between the wire pressing plate body 21 and the side positioning plate 22 forms a side positioning plate deformation angle R. The larger the side positioning plate deformation angle R is, the smaller the deformation degree of the side positioning plate 22 is allowed to be. This is to adjust the deformation degree of the side positioning plate 22 when the wire pressing plate 2 is pressed into the mounting seat 1. The size of the R angle is set according to specific needs. In this embodiment, the side positioning plate deformation angle R is 2 degrees.
[0030] When the wire pressing plate 2 is pressed vertically parallel to the mounting groove, the buckle wall 23 is squeezed and deformed inward by the horizontal bar 15 until the buckle wall 23 completely passes through the horizontal bar 15 and recovers its deformation, so that the outer sides of the two side positioning plates 22 are respectively abutted against the inner sides of the two horizontal bars 15, and the sides of the two buckle walls 23 away from the mounting plate 11 are respectively abutted against the sides of the two horizontal bars 15 close to the mounting plate 11, so that the wire pressing plate 2 is clamped and fixed to the mounting seat 1, and the limiting wall 24 is inserted into the limiting groove 18 and abuts against the mounting plate 11, so that the buckle wall 23 is buckled and fastened by the upward reverse thrust of the limiting wall 24 after abutting against the horizontal bar 15, and the reliability is better. At the same time, because the buckle wall 23 is surrounded by the protective wall 12 and the force-bearing wall 13 to form protection, it is difficult to remove the wire pressing plate 2 from the mounting seat 1 without the help of tools, thereby improving reliability and safety, and the fixing reliability of the power cord 10 is high.
[0031] In this embodiment, the first wire pressing teeth 17 are used to limit and fix the power cord 10 in the horizontal and vertical directions, and include a plurality of first wire pressing plates 171 extending in a direction parallel to the protective wall 12 and a plurality of first wire pressing cones 172 extending from the mounting plate 11. The plurality of first wire pressing plates 171 are arranged at intervals in a direction parallel to the force-bearing wall 13, and the first wire pressing cones 172 are disposed between two adjacent first wire pressing plates 171. The first wire pressing plates 171 are used to limit the horizontal direction of the power cord 10, and the first wire pressing cones 172 are used to limit the longitudinal direction of the power cord 10.
[0032] More preferably, in order to further limit and tighten the power cord 10, the wire crimping plate 2 also includes two groups of second wire crimping teeth 25 respectively extending downward from the wire crimping plate body 21, and the two groups of second wire crimping teeth 25 are respectively located between the limiting wall 24 and the two side positioning plates 22.
[0033] Each of the second wire pressing teeth 25 includes a plurality of second wire pressing plates 251 extending in a direction parallel to the protective wall 12 and a plurality of second wire pressing cones 252 protruding and extending from the wire pressing plate body 21. The plurality of second wire pressing plates 251 are arranged at intervals in a direction parallel to the force-bearing wall 13, and a second wire pressing cone 252 is provided between two adjacent second wire pressing plates 251.
[0034] The wire pressing plate 2 further includes four vertical pressing plates 26 which are formed by extending downward from the wire pressing plate body 21 and respectively abutting against the side of the two side positioning plates 22 close to the limiting wall 24 and the side of the limiting wall 24 close to the two side positioning plates 22. The cross-sectional area of each vertical pressing plate 26 gradually decreases from one end close to the wire pressing plate body 21 to one end close to the mounting plate 11. The arrangement of the vertical pressing plates 26 can limit and squeeze the peripheral side of the power cord 10 to form a further tightening effect.
[0035] In this embodiment, the bottom of the buckle wall 23 is chamfered to form a sliding gap, which allows the wire pressing plate 2 to be pressed into the mounting seat 1 more smoothly, thereby improving installation efficiency and making installation more convenient.
[0036] In order to improve the structural strength of the mounting seat 1 and the wire pressing plate 2, the mounting seat 1 is an integrally formed structure, and the wire pressing plate 2 is an integrally formed structure.
[0037] Compared with the prior art, the power cord fastening device of the utility model forms a receiving space by the protective wall and the load-bearing wall formed on the mounting seat, and divides the receiving space into a first wire-accommodating space and a second wire-accommodating space by the limiting wall, and at the same time forms a horizontal strip on the inner side of the two load-bearing walls, forms a wire groove on the two protective walls, forms a first wire-pressing tooth in the first wire-accommodating space and forms a limiting groove with the limiting wall; correspondingly, the wire-pressing plate is designed to include a wire-pressing plate body arranged opposite to the mounting plate, two side positioning plates respectively bent downward and extended from the opposite sides of the wire-pressing plate, two buckle walls bent and extended from the side positioning plates, and a limiting wall formed by the wire-pressing plate body extending downward; thus, during installation, after the power cord is passed through the mounting groove, it is only necessary to press the wire-pressing plate vertically toward the mounting seat. The two buckle walls are respectively abutted against one side of the two horizontal bars close to the mounting plate to form a buckle, and the outer sides of the two side positioning plates are respectively abutted against the inner sides of the two horizontal bars, and the limiting wall is inserted into the limiting groove and abuts against the mounting plate, thereby realizing that the wire pressing plate clamps the power cord in the mounting seat without the aid of any installation tools, and the installation is more convenient; the structural design of the wire pressing plate makes it symmetrical about the limiting wall, and it can be directly installed on the mounting seat without distinguishing the left and right directions, which effectively improves the installation efficiency; when disassembling, the part where the buckle wall and the horizontal bar are clamped is surrounded by the protective wall and the force-bearing wall, and it cannot be disassembled without the aid of tools, avoiding safety hazards and having higher safety and reliability; the cooperation between the buckle wall and the horizontal bar makes the wire pressing plate stressed all around, and the fastening is better.
