Description

Technical Field

[0001] This utility model relates to the technical field of terminal blocks, and in particular to a high-current terminal block that can be unlocked with one hand. Background Technology

[0002] With market demand, more and more high-current terminals are being used in various electrical connection products. Existing high-current terminals installed in electrical boxes or equipment generally consist of a terminal body and a housing. A conductive plate is connected to the terminal body, and the body is fixed to the housing of the electrical box or equipment by multiple screws. The housing and the terminal body are mostly fixed by multiple screws. Due to the limited space inside the electrical box or equipment, it is troublesome to disassemble the housing later, which is not conducive to maintenance. Therefore, how to design a high-current terminal that can unlock and disassemble the housing with one hand has become an urgent technical problem to be solved. Utility Model Content

[0003] In order to overcome the existing technical defects, the purpose of this utility model is to provide a high-current terminal block that can be unlocked with one hand to solve the above-mentioned technical problems.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] According to one aspect of this utility model, a high-current terminal block that can be unlocked with one hand is designed, comprising: a terminal body, a housing, an elastic snap-fit ​​component, and an unlocking component. The terminal body is provided with a snap-fit ​​plate, and the snap-fit ​​plate is provided with a snap-fit ​​portion. The housing is provided with a mounting groove and an unlocking rod that is laterally movable. The elastic snap-fit ​​component is disposed in the mounting groove, with its left end connected to the housing and its right end having an elastic inclined portion that can be driven to move by the unlocking rod. The elastic snap-fit ​​component is provided with a snap-fit ​​protrusion protruding to the outside of the housing. When the right end of the terminal body is inserted into the housing, the snap-fit ​​protrusion can snap into the snap-fit ​​portion to make the terminal body snap into the housing. When the unlocking component is placed on the housing and moved to the left, it can abut against the unlocking rod and move to the left to drive the elastic inclined portion to move, thereby disengaging the snap-fit ​​protrusion from the snap-fit ​​portion to achieve unlocking.

[0006] Using the above technical solution, when the high-current terminal needs to be disassembled and repaired, one hand holds the unlocking piece and places it on the housing and moves it to the left. The unlocking piece moves to the left and abuts against the unlocking rod, which in turn moves to the left and abuts against the elastic inclined part, causing the elastic inclined part to move away from the locking protrusion. This causes the locking protrusion to separate from the locking part, thus unlocking the housing. This can be done with one hand, making the disassembly of the housing simpler and more convenient, which is beneficial for the repair of high-current terminals.

[0007] To better address the aforementioned technical deficiencies, this utility model also offers a superior technical solution:

[0008] In some embodiments, the terminal body is provided with snap-fit ​​plates at its front and rear ends, the housing is provided with mounting grooves and unlocking rods that are laterally movable on its front and rear sides, and the two elastic snap-fit ​​members are correspondingly provided in the two mounting grooves.

[0009] In some embodiments, the unlocking component is detachably mounted across the right end of the housing, and when the unlocking component is mounted across the right end of the housing, the unlocking post on it corresponds left and right to the unlocking rod.

[0010] In some embodiments, the housing is provided with a sliding groove, and the unlocking member is provided with a slider. When the unlocking member straddles the housing, the slider is placed in the sliding groove and can slide laterally with the sliding groove.

[0011] In some embodiments, the unlocking rod is slidably fitted into a mounting hole on the housing, and a spring is sleeved on the left end of the unlocking rod. The left end of the spring abuts against the first stepped surface in the mounting hole, and the right end abuts against the second stepped surface on the unlocking rod.

[0012] The right end of the unlocking rod is provided with a limiting piece, and the housing is provided with an L-shaped limiting member. The limiting piece abuts against the limiting surface on the limiting member.

[0013] In some embodiments, the unlocking rod is provided with an anti-rotation guide plate, which slides laterally with a guide groove provided on the side wall of the mounting hole.

[0014] In some embodiments, the elastic snap-fit ​​member has an arc-shaped portion and a connecting portion at its left end, and a V-shaped portion and an overlapping portion that overlaps with the housing at its right end. A limiting mounting portion is provided in the mounting groove of the housing, and the arc-shaped portion and the connecting portion are limited and installed in the gap between the limiting mounting portion and the housing.

[0015] In some embodiments, the housing is provided with a limiting groove, and the unlocking member is provided with a limiting block that cooperates with the limiting groove to limit the leftward movement distance of the unlocking member.

[0016] In some embodiments, a first sealing ring that makes sealing contact with the housing is fitted in the first annular groove at the right end of the terminal body, and a second sealing ring is fitted in the second annular groove at the left end.

[0017] In some embodiments, the right end of the housing is threaded with a tail cap and has a cable sealing ring inside. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0029] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, 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.

[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as setting, installing, connecting, and fixing should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0031] refer to Figures 1 to 8 As shown, the present invention provides a high-current terminal block that can be unlocked with one hand, comprising: a terminal body 1, a housing 2, an elastic snap-fit ​​component 3, and an unlocking component 4.

[0032] The terminal body 1 is provided with a snap-fit ​​plate 10 and a conductive plate 5. One or two snap-fit ​​plates 10 are provided; in this embodiment, two snap-fit ​​plates 10 are preferably provided, with the two snap-fit ​​plates 10 correspondingly disposed on the front and rear sides of the terminal body 1. Each snap-fit ​​plate 10 is provided with a snap-fit ​​part 101, which is a groove or a through hole; in this embodiment, the snap-fit ​​part 101 is preferably a through hole. The housing 2 is provided with one or two mounting grooves 20 and one or two unlocking rods 6 that are laterally movable. In this embodiment, one mounting groove 20 is preferably provided on the front and rear sides of the housing 2, and the two unlocking rods 6 on the front and rear sides of the housing 2 are respectively provided with a mounting groove 20. An unlocking rod 6 is laterally movable within the mounting hole 21. A spring 61 is fitted on the left end of the unlocking rod 6, and the left end of the spring 61 abuts against the first stepped surface inside the mounting hole 21, while the right end abuts against the second stepped surface on the unlocking rod 6. A limiting piece 62 is provided on the right end of the unlocking rod 6, and an L-shaped limiting member 22 is provided on one side of the mounting hole 21 at the right end of the housing 2. The limiting piece 62 abuts against the limiting surface 221 on the limiting member 22, thereby restricting the unlocking rod 6 within the mounting hole 21. The abutment between the limiting piece 62 and the limiting surface 221 is formed by the elastic driving force of the spring 61 on the unlocking rod 6 to the right. The unlocking rod 6 is provided with one or two anti-rotation guide plates 63. The anti-rotation guide plates 63 are laterally slidably engaged with the guide grooves 23 provided on the side wall of the mounting hole 21. The anti-rotation guide plates 63 can play a guiding role on the one hand, and prevent the unlocking rod 6 from rotating on the other hand. If the unlocking rod 6 rotates, it will cause the limiting plate 62 and the limiting surface 221 on the limiting member 22 to misalign, resulting in the unlocking rod 6 separating from the mounting hole 21.

[0033] The number of elastic snap-fit ​​pieces 3 is the same as the number of mounting slots 20. Two elastic snap-fit ​​pieces 3 are correspondingly set in two mounting slots 20. The elastic snap-fit ​​pieces 3 are provided with snap-fit ​​protrusions 31 protruding to the outside of the housing 2. The middle part of the elastic snap-fit ​​pieces 3 is horizontal. The left end of the elastic snap-fit ​​pieces 3 is connected to the housing 2. Specifically, the left end of the elastic snap-fit ​​pieces 3 has an arc-shaped part 32 and a connecting part 33. A limiting mounting part 24 is provided in the mounting slot 20 of the housing 2. The arc-shaped part 32 and the connecting part 33 are limited and installed in the gap between the limiting mounting part 24 and the housing 2. In actual production, the lower opening of the mounting slot 20 is open to the outside. When the elastic snap-fit ​​pieces 3 are placed in the mounting slot 20 and the arc-shaped part 32 and the connecting part 33 are placed in the gap, a stop block is welded below the mounting slot 20 to seal the opening of the mounting slot 20.

[0034] The right end of the elastic latching member 3 has a V-shaped portion 34, an elastic inclined portion 35, and an overlapping portion 36. The elastic inclined portion 35 corresponds to the unlocking rod 6. When the unlocking rod 6 moves to the left, it abuts against the elastic inclined portion 35 and moves away from the latching protrusion 31 (i.e., towards the inside of the housing 2). The movement of the elastic inclined portion 35 can move the V-shaped portion 34 and the latching protrusion 31 together. The overlapping portion 36 overlaps and contacts a plane inside the housing 2. The elastic latching member 3, the arc-shaped portion 32, the connecting portion 33, the V-shaped portion 34, the elastic inclined portion 35, and the overlapping portion 36 are an integral structure, which is a carbon steel spring, an alloy steel spring, a stainless steel spring, a copper alloy spring, or a nickel alloy spring.

[0035] The unlocking component 4 has an unlocking post 41 on the lower left side, a slider 42 and a limiting block 43 on the upper part. The housing 2 is provided with a sliding groove 25 and a limiting groove 26. The unlocking component 4 is detachably mounted across the right end of the housing 2. When the unlocking component 4 is mounted across the housing 2, the two sliders 42 are placed in the two sliding grooves 25, and the limiting block 43 is placed in the limiting groove 26. The two unlocking posts 41 correspond to the two unlocking rods 6 on the left and right. When the unlocking component 4 is moved to the left, the sliders 42 and the sliding grooves 25 slide laterally to guide the movement. The unlocking posts 41 can abut against the unlocking rods 6 and move to the left. The limiting block 43 moves to the left and contacts the left side of the limiting groove 26 to limit the leftward movement distance of the unlocking component 4.

[0036] A first sealing ring 71 fits into the first annular groove on the right end of the terminal body 1, and a second sealing ring 72 fits into the second annular groove on the left end. A tail cap 8 is threaded onto the right end of the housing 2, and a cable sealing ring 9 is provided inside.

[0037] When the right end of the terminal body 1 is inserted into the housing 2, the two snap-fit ​​protrusions 31 are snapped into the two snap-fit ​​parts 101 respectively, so that the terminal body 1 and the housing 2 are snapped together. The first sealing ring 71 is in sealing contact with the inner side wall of the housing 2, which plays a sealing connection role. When the housing 2 needs to be removed, hold the unlocking piece 4 with one hand, straddle the housing 2 and move it to the left. The unlocking post 41 moves to the left and abuts against the unlocking rod 6. The unlocking rod 6 moves to the left and abuts against the elastic tilting part 35 and drives the elastic tilting part 35 to move away from the snap-fit ​​protrusion 31. The snap-fit ​​protrusion 31 is separated from the snap-fit ​​part 101 in conjunction, thereby unlocking the housing 2. Then the housing 2 can be removed by moving it to the right.

[0038] In some embodiments, the left end of the unlocking lever 6 is provided with an inclined surface parallel to the elastic inclined portion 35, which can provide a better driving movement effect on the elastic inclined portion 35.

[0039] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
