Description

Technical Field

[0001] The utility model relates to the field of household appliances, and particularly relates to a wire clamp and an electrical appliance using the same. Background Art

[0002] The existing wire clamp includes a base and a cover. The top surface of the base and the bottom surface of the cover are both flat. During use, the cover is covered on the base and fixedly locked through fasteners. The wire is clamped in the channel between the top surface of the base and the bottom surface of the cover. Since the channel can only be adjusted in height, the wire lacks horizontal limitation, which not only fails to effectively limit the wire, but also easily loosens due to deviation, has poor tensile strength, affects the clamping reliability, and also causes local stress on the wire due to the mismatch between the cross-sectional profile of the channel and the cross-sectional profile of the wire, resulting in local damage to the wire and affecting the use experience. Summary of the Utility Model

[0003] In order to solve the deficiencies of the prior art, the utility model provides a wire clamp and an electrical appliance using the same. A clamping opening with a large opening and a small cavity is arranged at the notch of the cover groove of the cover. The clamping opening and the top surface of the base are used to form a channel for clamping the wire. The width and height of the channel can be adjusted synchronously, which not only effectively improves the clamping force, but also can match the cross-sectional profile of the wire, enhancing the use experience.

[0004] The utility model is realized in the following way: A wire clamp includes a base and a cover covered on the base. A cover groove opening downward is arranged in the cover. A clamping opening is arranged at the notch of the cover groove. The clamping opening is in the shape of a large opening and a small cavity. The clamping opening and the top surface of the base enclose to form a channel for clamping the wire. When the base is inserted into the cover, the width of the channel decreases synchronously with the height of the channel, so that the cross-sectional size of the channel decreases and clamps the wire. By arranging a clamping opening with a large opening and a small cavity at the notch of the cover groove of the cover, and using the clamping opening and the top surface of the base to form a channel for clamping the wire, the width and height of the channel can be adjusted synchronously, so that the channel can apply horizontal and vertical clamping forces to the wire, which not only effectively improves the clamping force and the tensile strength, but also can match the cross-sectional profile of the wire, enhancing the use experience.

[0005] Preferably, there are two clamping openings, which are respectively arranged in the middle sections of the front and rear edges of the notch of the cover groove, so that the wire passes through the channel and is clamped and fixed by the clamping openings and the top surface of the base. The wire passes through the front and rear edges of the notch of the cover groove through the notch, which not only facilitates the clamping of the wire by the cover and the base, but also ensures that the wire can smoothly pass through the channel.

[0006] Preferably, inclined guiding and pushing surfaces are provided on both sides of the inner cavity of the clamping opening. The guiding and pushing surfaces drive the wires to converge towards the middle through vertical movement, so that the channel clamps the wires. The guiding and pushing surfaces are inclined, which can not only move downward synchronously with the cover and apply a vertical force to the wires, but also convert the vertical force into a horizontal force that drives the guides to gather towards the middle horizontally, so that the height and width of the cross-sectional profile of the channel can be adjusted synchronously, playing a role in clamping, shaping and regularizing the multi-strand wires.

[0007] Preferably, the vertical cross-section of the clamping opening is an isosceles triangle, and the guiding and pushing surface is a plane, which applies a uniform horizontal force to the wires synchronously with the downward pressing of the cover to ensure effective clamping of the wires.

[0008] Preferably, the vertical cross-section of the clamping opening is an arc shape, and the guiding and pushing surface is an arc surface, which applies a gradually decreasing horizontal force to the wires with the downward pressing of the cover to ensure effective regularization of the wires.

[0009] Preferably, both sides of the cavity of the cover groove are sleeved on both sides of the base, and the horizontal cross-sectional profile of the cover groove matches the top surface profile of the base, so that the inner wall of the cover groove is attached to the side wall of the base and guides the cover to be vertically covered on the base. The middle of the notch of the cover groove forms a channel by opening a clamping opening to enclose with the top surface of the base. Both sides of the cover groove can be vertically sleeved on both sides of the base, playing a role in guiding the lifting of the cover to ensure that the wires are vertically clamped and obtain a horizontal force through the guiding and pushing surfaces.

[0010] Preferably, vertical screw holes are provided on both sides of the top surface of the base, and through holes vertically penetrating are provided on both sides of the cover. When the cover is properly closed, it is screwed to the corresponding screw holes through fasteners passing through the through holes, so that the cover is fixedly connected to the base in a preset posture and clamps the wires by reducing the cross-sectional size of the channel. The screw holes and the through holes are vertically aligned, which is convenient for the vertical insertion and screwing of the fasteners to ensure that the cover and the base vertically clamp the wires.

[0011] Preferably, a clamping groove is formed by recessing in the middle of the top surface of the base, and a clamping plate is provided in the middle of the cover groove. During installation, the clamping plate drives the corresponding section of the wire to bend downward and embed into the clamping groove. The bottom surface of the base drives the wire to embed upward into the cover groove, and the clamping plate drives the wire to embed downward into the clamping groove, and the tensile strength is improved by setting a bent channel.

[0012] Preferably, the base includes two vertically arranged stud bolts and a connecting plate bridging between the corresponding sides of the stud bolts. The screw holes are provided in the stud bolts, and the clamping groove is formed by enclosing between the connecting plates. The base includes stud bolts with screw holes and a connecting plate, which effectively simplifies the structure and is convenient for processing and production.

[0013] An electrical appliance using the said wire clamp includes a housing and functional components arranged inside the housing. The base is arranged on the housing so that the wire is clamped by the channel and laid along the surface of the housing. The wire is fixed to the housing by the wire clamp so that the wire can be laid along the surface of the housing, preventing the wire from being suspended, increasing the difficulty of assembly and maintenance, ensuring the safety of the wire, and enhancing the user experience.

[0014] Preferably, the base and the housing are of an integral structure, which not only ensures the connection reliability between the base and the housing but also improves the processing efficiency without the need for independent processing and assembly.

[0015] The beneficial effects of the present utility model: A clamping opening with a large opening and a small cavity is provided at the notch of the cover groove of the cover. The clamping opening and the top surface of the base are used in cooperation to form a channel for clamping the wire. The width and height of the channel can be adjusted synchronously, so that the channel can apply a horizontal clamping force and a vertical clamping force to the wire, effectively improving the clamping strength, enhancing the anti-pulling strength, and matching the cross-sectional profile of the wire, thus enhancing the user experience.

[0021] The following further illustrates the substantial features of the present utility model in conjunction with the drawings of the specification and the detailed description of the embodiments.

[0022] Embodiment 1:

[0023] This embodiment provides a wire clamp.

[0024] As Figure 1 and 2A wire clamp as shown is composed of a base 1 and a cover 2 covering the base 1. A downwardly exposed cover groove 3 is provided inside the cover 2. A clamping opening 4 is provided at the notch of the cover groove 3. The clamping opening 4 is large at the opening and small at the cavity. The clamping opening 4 and the top surface of the base 1 enclose a channel for clamping a wire 5. When the base 1 is inserted into the cover 2, the width of the channel decreases synchronously with the height of the channel, so that the cross-sectional dimension of the channel decreases and the wire 5 is clamped. By providing a clamping opening 4 with a large opening and a small cavity at the notch of the cover groove 3 of the cover 2, a channel for clamping the wire 5 is formed by the cooperation of the clamping opening 4 and the top surface of the base 1. The width and height of the channel can be adjusted synchronously, so that the channel can apply a horizontal clamping force and a vertical clamping force to the wire 5, effectively improving the clamping strength and the tensile strength, and can also match the cross-sectional contour of the wire 5 to improve the use experience.

[0025] In this embodiment, there are two clamping openings 4, which are respectively arranged in the middle of the front and rear edges of the notch of the cover groove 3, so that the wire 5 passes through the channel and is clamped and fixed by the clamping openings 4 and the top surface of the base 1. Both sides of the cavity of the cover groove 3 are sleeved on both sides of the base 1. The horizontal cross-sectional contour of the cover groove matches the top surface contour of the base 1, so that the inner wall of the cover groove is attached to the side wall of the base 1 and guides the cover 2 to be vertically covered on the base 1. During installation, first, place the wire 5 in the middle of the top surface of the base 1; then, cover the cover 2 on the base 1 from top to bottom, and insert both sides of the base 1 into both sides of the cover groove 3, so that the wire 5 is clamped between the clamping opening 4 and the middle of the base 1; finally, a fastener 9 passes through a through hole 8 provided on the side of the cover 2 and is screwed and locked with a corresponding screw hole 7 provided on the base 1. The base 1 is inserted into the cover groove 3 and cooperates with the clamping opening 4 to clamp the wire 5, ensuring that the wire 5 is firmly clamped.

[0026] In this embodiment, inclined guiding and pushing surfaces 6 are provided on both sides of the inner cavity of the clamping opening 4. The guiding and pushing surfaces 6 drive the wire 5 to converge towards the middle through vertical movement, so that the channel clamps the wire 5. The clamping opening 4 is large at the opening and small at the cavity. The two side cavity walls of the inner cavity of the clamping opening 4 form the guiding and pushing surfaces 6, so that the upper edges of the guiding and pushing surfaces 6 approach each other. During use, the base 1 will be gradually inserted into the cover groove 3 under the screwing action of the fastener 9. During this process, the cross-sectional area of the channel formed between the middle of the base 1 and the clamping opening 4 will gradually decrease, specifically reflected in the decrease of the height and width of the channel, so that the wire 5 will be squeezed towards the middle by the channel with a decreasing cross-sectional area, not only vertically clamping the wire 5 by applying a vertical force, but also horizontally clamping the wire 5 by the horizontal force formed by the conversion of the guiding and pushing surfaces 6, effectively eliminating the gap between the wires 5, ensuring that the wires 5 are concentrated and regular, and ensuring that the tensile strength meets the use requirements by improving the clamping strength.

[0027] In this embodiment, the vertical cross-section of the clamping opening 4 is an isosceles triangle, and the guiding and pushing surface 6 is a plane. The inclination angles of all regions of the guiding and pushing surface 6 are the same, ensuring that the force conversion efficiency of all regions of the guiding and pushing surface 6 is consistent, and ensuring that the wire 5 can be effectively regularized towards the middle. In addition, the vertical cross-section of the clamping opening 4 can also be arc-shaped, and the guiding and pushing surface 6 is an arc surface, so that the force conversion efficiency of all regions of the guiding and pushing surface 6 is different, and it has a good vertical clamping effect on the wire 5, which should also be regarded as a specific implementation manner of this embodiment.

[0028] In this embodiment, vertical screw holes 7 are provided on both sides of the top surface of the base 1, and vertical through holes 8 are provided on both sides of the cover 2. When the cover 2 is properly closed and screwed to the corresponding screw holes 7 through fasteners 9 passing through the through holes 8, the cover 2 is fixedly connected to the base 1 in a preset posture and clamps the wire 5 by reducing the cross-sectional size of the channel. The diameter of the through hole 8 is between the diameters of the middle section and the tail end of the fastener 9, which not only ensures that the periphery of the through hole 8 can contact the periphery of the tail end of the fastener 9, but also ensures that the middle section of the fastener 9 can pass through the through hole 8 and be screwed to the screw hole 7, ensuring that the wire 5 is clamped towards each other between the base 1 and the cover 2 through the fastener 9. Screw holes 7 are provided on both sides of the base 1, and through holes 8 are provided on both sides of the cover 2, ensuring that both sides of the cover 2 are evenly stressed and move towards the base 1 synchronously.

[0029] In this embodiment, a card slot 10 is formed by a depression in the middle of the top surface of the base 1, and a clamping plate 11 (as Figure 3 shown) is provided in the middle of the cover slot 3. During installation, the clamping plate 11 drives the corresponding section of the wire 5 to bend downward and embed into the card slot 10. After installation, the vertical projection of the clamping plate 11 falls into the card slot 10, and the vertical projection of the base 1 falls into the cover slot 3, ensuring that the clamping plate 11 and the card slot 10, and the cover slot 3 and the base 1 can be vertically inserted synchronously, thereby ensuring that the height and width of the cross-sectional profile of the channel can be increased and decreased synchronously.

[0030] In this embodiment, the base 1 includes two vertically arranged stud bolts 12 and a connecting plate 13 (as Figure 4 shown) bridging between the corresponding sides of the stud bolts 12. The screw holes 7 are provided in the stud bolts 12, and the connecting plates 13 enclose to form the card slot 10. The horizontal cross-sectional profiles of the base 1 are the same, which is convenient for injection molding, effectively simplifies the structure and improves the processing efficiency, and thus reduces the processing cost.

[0031] Embodiment Two:

[0032] Compared with Embodiment One, this embodiment provides an electrical appliance.

[0033] An electrical appliance using the wire clamp comprises a housing and functional components arranged inside the housing. The base 1 is arranged on the housing so that the wire 5 is clamped by the channel and laid along the surface of the housing. The functional components are used to realize the functions of the electrical appliance, and the wire 5 provides electrical energy and control signals for the functional components to ensure the normal operation of the functional components. The base 1 is arranged on the housing so that the wire 5 can be fixedly connected to the housing through the cover 2, preventing the wire 5 from being disengaged from the functional components when being pulled due to being clamped in a suspended manner, effectively improving the anti-pulling performance.

[0034] In this embodiment, the base 1 and the housing are of an integral structure, which is convenient for the base 1 and the housing to be integrally formed by injection molding, improving both the connection reliability and the convenience of processing and assembly.

[0035] Other structures and effects of the wire clamp described in this embodiment are the same as those in Embodiment 1 and will not be elaborated herein.
