Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, and in particular to a fence-type terminal block. Background Technology

[0002] Terminals are components that connect a battery to an external conductor. In electrical engineering, terminals often refer to wiring terminals, also called wiring terminals. Types include single-hole, double-hole, plug, hook, etc. In terms of materials, they include silver-plated copper, zinc-plated copper, copper, aluminum, iron, etc. Their main function is to transmit electrical signals or conduct electricity.

[0003] Terminal blocks are accessories used to achieve electrical connections. With the increasing level of industrial automation and the increasingly stringent and precise requirements of industrial control, the use of terminal blocks is gradually increasing. Among them, fence-type terminal blocks are widely used due to their simple structure and low cost. Existing fence-type terminal blocks usually have threaded holes machined on the pins for screw mating, which has the disadvantage of insufficient torque. However, patent CN205004485U discloses a fence-type terminal block that has a cavity for setting a hexagonal nut at the bottom of the main plastic part. By mating the hexagonal nut with the screw, the disadvantage of insufficient torque is solved.

[0004] However, existing patents still have the problem of complicated processing. The cavity at the bottom of the main plastic part needs to be processed into a shape that fits the hexagonal nut. Otherwise, when tightening the screw, the hexagonal nut will cause stripping between the cavity and the screw. Processing the cavity that fits the hexagonal nut requires a fairly complicated process. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings and deficiencies of the existing technology and to provide a fence-type terminal block. This utility model not only provides a groove that matches the apex of the hexagonal nut by opening a groove on the inner side wall of the mounting hole, which not only fits and limits the hexagonal nut to prevent stripping, but also makes the groove easy to process and provides a more secure and reliable installation of power cords.

[0006] The technical solution adopted by this utility model is as follows: a fence-type terminal block includes a housing body, fasteners, pins and hexagonal nuts. The fasteners are threadedly connected to the pins and the hexagonal nuts. The bottom of the housing body is provided with a plurality of mounting holes for the pins to pass through. A partition is provided between every two mounting holes. The inner sidewall of each mounting hole is provided with at least one slot that matches the apex of the hexagonal nut. The hexagonal nut is set in the mounting hole by fitting into the slot.

[0007] The cross-section of the slot is an isosceles triangle.

[0008] The slot has a step.

[0009] The depth of the step relative to the end face of the shell body is less than the thickness of the hexagonal nut.

[0010] The two inner side walls of the mounting hole are provided with clamping grooves.

[0011] The edge of the clamping groove is provided with a chamfer.

[0012] The pin side is provided with a protruding block for clamping with the shell body.

[0013] The mounting hole is further provided with a bottom plate connecting the two inner side walls.

[0014] The beneficial effects of the utility model are as follows: the utility model discloses a clamping groove which is adapted to the top angle of the hexagonal nut is arranged on the inner side wall of the mounting hole, which can not only limit the hexagonal nut to prevent wire slipping, but also is very simple to process, and the clamping groove is processed on the basis of the mounting hole for mounting the pin, the clamping groove is communicated with the mounting hole, so that the processing procedure is greatly reduced, and the power line is more firm and reliable when being installed.

[0021] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model will be further described in detail below in combination with the drawings.

[0022] It should be noted that all uses of "first" and "second" in the embodiments of this utility model are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of this utility model. Subsequent embodiments will not explain this in detail.

[0023] The directional and positional terms used in this utility model, such as "up," "down," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side," are merely for reference to the accompanying drawings. Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0024] like Figs. 1 to 4 As shown, this is an embodiment of the present invention, a fence-type terminal block, including a housing body 1, fasteners 2, pins 3 and hexagonal nuts 4. The fasteners 2 pass through the pins 3 and are threadedly connected to the hexagonal nuts 4. The bottom of the housing body 1 is provided with a plurality of mounting holes 5 for the pins 3 to pass through. A partition 6 is provided between every two mounting holes 5. The inner sidewall of each mounting hole 5 is provided with at least one groove 7 that matches the apex of the hexagonal nut 4. The hexagonal nut 4 is set in the mounting hole 5 by fitting into the groove 7.

[0025] The advantages of this design are as follows: By creating a groove on the inner wall of the mounting hole that matches the apex of the hexagonal nut, this invention not only secures the hexagonal nut and prevents stripping, but also simplifies the machining of the groove. The groove is machined on top of the mounting hole used for mounting the pins, and it communicates with the mounting hole, significantly reducing machining steps and providing greater stability and reliability when installing the power cord. The fastener uses screws from existing technology.

[0026] Furthermore, the cross-section of the card slot 7 is an isosceles triangle.

[0027] The advantages of this design are as follows: the cross-section of the slot is an isosceles triangle, which is more compatible with the apex angle of the hexagonal nut; when slots are provided on both inner walls of the mounting hole, they can be symmetrical with each other, making processing more convenient; and the installation of the hexagonal nut is flatter and less labor-intensive.

[0028] Furthermore, the slot 7 is provided with a step 8.

[0029] The beneficial effects of this design are as follows: the step is used to limit and block the bottom surface of the hexagonal nut, so that the hexagonal nut will not fall directly from below the mounting hole when the screw is removed.

[0030] Furthermore, the depth of the step 8 relative to the end face of the outer shell body 1 is less than the thickness of the hexagonal nut 4.

[0031] The beneficial effects of such an arrangement are as follows: the hexagonal nut can be more firmly installed in the clamping groove, otherwise the hexagonal nut installed in the clamping groove will have a certain gap, and the hexagonal nut can reciprocate in the clamping groove along the axial direction of the screw, resulting in unstable wiring.

[0032] Further arrangement, the two inner side walls of the mounting hole 5 are symmetrically provided with clamping grooves 7.

[0033] The beneficial effects of such an arrangement are as follows: the two top corners of the hexagonal nut are formed to fit, so that the hexagonal nut fits more firmly, and the clamping grooves on both sides are symmetrical, which is also convenient for processing.

[0034] Further arrangement, the edge of the clamping groove 7 is provided with a chamfer 9.

[0035] The beneficial effects of such an arrangement are as follows: the chamfer is used to facilitate the disassembly and assembly of the hexagonal nut, and the hexagonal nut can be slid into the clamping groove along the chamfer.

[0036] Further arrangement, the pin 3 is provided with a protrusion 10 on the side surface for clamping with the shell body 1.

[0037] The beneficial effects of such an arrangement are as follows: the pin is clamped with the shell body through the protrusion for blocking the hexagonal nut, preventing the hexagonal nut from being pulled out from the open direction of the clamping groove, and the pin is clamped between the hexagonal nut and the screw.

[0038] Further arrangement, the mounting hole 5 is further provided with a bottom plate 11 connecting the two inner side walls.

[0039] The beneficial effects of such an arrangement are as follows: the bottom plate improves the overall structural strength and can also block dust from entering.

[0040] The above disclosure is only the preferred embodiment of the utility model, and of course cannot limit the scope of the utility model, so equivalent changes made according to the utility model claims still belong to the scope covered by the utility model.
