Abstract
Description
Technical Field
[0001] This utility model relates to the field of power equipment technology, and in particular to a double-sided terminal current guiding device clamp. Background Technology
[0002] Traditional wire clamps are mostly single-sided contact designs, which are prone to loosening or poor contact due to uneven force. For example, Chinese utility model patent application number CN201620409324.5, entitled "An Improved Parallel Groove Wire Clamp with Terminal Blocks," is relevant. (Or see attached...) Figure 7 The conventional equipment clamp shown includes a Y-shaped main body with two branches for mounting multiple clamping blocks. A single plate at the bottom of the main body serves as the contact surface, which is connected to an equipment connector via multiple bolts. Since there is only one contact surface, there is a risk of poor contact.
[0003] Therefore, there is an urgent need for a wire clamp that provides more stable contact and more even force distribution. Utility Model Content
[0004] The purpose of this invention is to provide a double-sided terminal guide device clamp that uses bidirectional contact clamping technology to fix the device connector with two flat plates, so that the device connector can be clamped in two directions at the same time, achieving double the contact area and more uniform force distribution.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A double-sided terminal flow guiding device wire clamp includes two wire clamps with identical structures. Each wire clamp includes a main body, a plurality of pressure blocks, and fasteners.
[0007] Each of the main bodies is L-shaped and includes mutually perpendicular flat plates and clamping plates;
[0008] Multiple pressure blocks are respectively fixed to the clamping plate by fasteners, and grooves are respectively opened on the opposite sides of the pressure blocks and the clamping plate;
[0009] The two main bodies are arranged in a staggered manner to form a U-shape. The equipment joint is clamped between the two opposing plates by bolts. The two clamping plates are arranged at both ends of the length direction of the two plates, and the grooves of the two clamping plates face each other.
[0010] Furthermore, the opposite sides of the two flat plates are thinned relative to the opposite sides of the two clamping plates, so that clamping spaces for accommodating the device connector are opened on the opposite sides of the two flat plates.
[0011] Furthermore, the flat plate and the clamping plate are connected by rounded corners.
[0012] Furthermore, the fasteners are bolts, nuts, spring washers, and flat washers.
[0013] Furthermore, the flat washer is a rubber washer.
[0014] Furthermore, the four sides of the top surface of the pressing block are rounded; each pressing block has mounting holes for connecting the fasteners at both ends of the width direction of the groove.
[0015] Furthermore, the pressure block has a groove hole at one end near the length of the groove, and the height and width of the groove hole are greater than those of the groove.
[0016] In the above technical solution, the double-sided terminal flow guiding device clamp of this utility model has the following beneficial effects:
[0017] This device's wire clamps employ bidirectional contact clamping technology. Through a symmetrical contact surface design, the connectors can be tightened simultaneously in two directions, doubling the contact area. This structure significantly improves current conduction efficiency while enhancing mechanical stability, making it particularly suitable for high-load applications. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0029] It should be noted that the terms "above," "one end," "up," etc. used in this document indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Similar expressions are only for illustrative purposes and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "part," "two parts," etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0030] like Figure 1-3 The double-sided terminal flow guiding device clamp shown includes two clamps with identical structures. Each clamp includes a body 11, a plurality of pressure blocks 13, and fasteners.
[0031] Each main body 11 is L-shaped and includes mutually perpendicular flat plates 111 and clamping plates 112.
[0032] Multiple pressure blocks 13 are fixed to the clamping plate 112 by fasteners. Wire grooves are formed on opposite sides of the pressure blocks 13 and the clamping plate 112. The length direction of the wire grooves is along the length direction of the clamping plate 112, and the multiple pressure blocks are also arranged along the length direction of the clamping plate 112. After the wire is placed into the wire groove of the clamping plate 112, the wire groove of the pressure block 13 snaps onto the wire, and the pressure block 13 and the clamping plate 112 are fixed together by fasteners. The number of pressure blocks 13 is at least two, such as... Figure 1-3 The clamping plate 112 shown has four pressure blocks. Figure 3 To showcase the cable channel, a pressure block was hidden above.
[0033] Two main bodies 11 are arranged in a staggered manner, forming a U-shape with the double-sided terminal guide clamp. One clamp is flipped along its thickness to form the other clamp, and the distance between the two clamps is adjusted. Two flat plates 111 are arranged opposite each other along their thickness direction, with a gap and parallel arrangement between them. The two plates form the root of the U-shape to clamp the two sides of the equipment connector. Two clamping plates are arranged at both ends along the length of the two flat plates, with their grooves facing each other. Two clamping plates 112 are also arranged at both ends along the length of the two flat plates 111, forming two branches of the U-shape. The equipment connector is clamped between the two opposing flat plates 111 by bolts. The two flat plates 111 are then fixed to the equipment connector on-site with bolts. This design is suitable for equipment connectors of various thicknesses, and the bolt length can be adjusted on-site for different applications.
[0034] Preferred, such as Figure 2 The flat plates of the clamping device connector shown are thinned on opposite sides relative to the opposite sides of the two clamping plates 112, so that clamping spaces for accommodating the device connector are opened on opposite sides of the two flat plates 111. This facilitates reducing the volume of the two wire clamps in the thickness direction. More preferably, the thickness of both sides of the flat plate 111 is smaller than the thickness of both sides of the clamping plate 112.
[0035] Preferably, the flat plate 111 and the clamping plate 112 are connected by rounded corners. Each main body 11 is generally L-shaped, but the corners are rounded to achieve a smooth transition.
[0036] Preferably, the fasteners are bolts, nuts, spring washers, and flat washers. After the bolt with a nut passes through the pressure block 13 and the clamping plate 112, the flat washer, spring washer, and nut are put on in sequence to fasten the pressure block 13 and the clamping plate 112.
[0037] More preferably, the flat washer is a rubber washer. The spring washer uses a disc spring made of 50CrV4 material. After being deformed under load, it can store a certain amount of potential energy. When the bolt loosens, the disc spring releases some potential energy to maintain the pressure between the connections, providing strong buffering and vibration absorption capabilities. The rubber washer uses CU rubber, a saturated polymer with excellent aging resistance, weather resistance, electrical insulation properties, chemical corrosion resistance, and impact elasticity. Using rubber washers can effectively compensate for loosening between the wire and the clamp caused by wire creep; the hardness of CU rubber is much lower than the surface hardness of aluminum wire, and as a filler between the wire and the clamp, it can prevent the wire from being worn; as a low-temperature resistant rubber, CU rubber can ensure that the rubber performance does not change within ±40℃, thus not affecting the product performance.
[0038] Preferred, such as Figure 4-6The pressure block 13 shown is a rectangular block with rounded corners on its top surface to prevent corona discharge. Then, mounting holes for fasteners are provided at both ends of the width of each pressure block 13 in the groove.
[0039] More preferably, such as Figure 4-6 The pressure block 13 shown has a recessed hole 131 at one end near the length of the wire groove. A recessed hole is also formed near the end of the pressure block in the wire groove. The height and width of the recessed hole 131 are larger than the wire groove. The recessed hole 131 effectively enlarges part of the wire groove. The opening size of the recessed hole 131 is larger than the wire groove. The function of the recessed hole is to prevent damage to the wire and to prevent the wire groove from squeezing the wire. The above description only illustrates certain exemplary embodiments of this utility model. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of this utility model. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of this utility model.
