Description

Technical Field

[0001] This utility model relates to the field of electrical connections, specifically a manual tool for assembling terminals. Background Technology

[0002] Terminal blocks are accessories used to achieve electrical connections. Industrially, they fall under the category of connectors. With increasing industrial automation and more stringent and precise industrial control requirements, the use of terminal blocks is gradually rising. However, the current conventional practice is to manually connect the wires to the metal contacts. Manually positioning the wires and metal contacts is difficult, and it's impossible to control the insertion force when inserting the metal contact into the wire's connection hole. Excessive force can damage the product, while insufficient force can result in improper insertion. In summary, the entire assembly process is time-consuming, labor-intensive, inefficient, costly, and leads to inconsistent product quality.

[0003] To improve efficiency, some fully automated equipment is now available, such as those disclosed in Chinese patent applications 201821559723.5 and 202011344730.5. However, these devices are often complex in structure, expensive, and require a large area, making them unsuitable for situations where efficiency is not a primary concern but cost is a critical factor.

[0004] Therefore, further improvements are needed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a manual tool for terminal assembly that addresses the shortcomings of the existing technology, thereby improving efficiency and saving costs.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problem is: a terminal assembly manual tool, characterized in that: the manual tool includes:

[0007] support;

[0008] A wire positioning component is fixed to a bracket. The wire positioning component includes a body and a first positioning part for positioning the wire of the terminal to be assembled. The first positioning part is located at the end of the body away from the bracket.

[0009] A metal sheet positioning component, comprising a second positioning part for positioning a metal sheet to be assembled with a wire, the second positioning part being fixed relative to the body and not higher than the top surface of the body, the metal sheet maintaining a tendency to move upward out of the second positioning part;

[0010] A push block includes a push block body disposed on a wire positioning member and a metal sheet positioning member. The bottom surface of the push block body is recessed upwards to form a receiving groove. The thickness of the receiving groove is equal to the thickness of the metal sheet, ensuring that only one metal sheet can enter the receiving groove upwards from the second positioning part at any given time.

[0011] The manual operating part is movably connected to the bracket and can be pressed to push the push block to move along the first direction toward the first positioning part, thereby connecting the metal plate inside the push block body with the wire end of the first positioning part.

[0012] By setting up wire positioning components and metal sheet positioning components, the wires and metal sheets to be assembled can be positioned conveniently, and the metal sheets can be automatically moved up into the push block. This allows for easy pushing out of one metal sheet at a time to connect with the wire when operating the manual operation unit. The structure is simple and the manual operation is easy, which can improve efficiency and save costs.

[0013] To facilitate fixing the wire in the first direction so that it can be connected to the movable metal piece in a fixed position during assembly, the first positioning part includes a first positioning block and a first positioning groove. The first positioning groove is formed by the top surface of the first positioning block being recessed downwards. The first positioning groove passes through the first positioning block along the first direction. The first positioning groove is at least partially flared, and the larger diameter of the flared opening is closer to the body than the smaller diameter of the flared opening.

[0014] The conductor includes a lead wire and a connecting portion located at the end of the lead wire. The metal sheet is inserted into the connecting portion, the lead wire passes through the first positioning groove, and the connecting portion abuts against the small diameter part of the flared mouth.

[0015] To prevent the wire from moving vertically, the first positioning part also includes a first stop block, which is at least disposed above the flared opening of the first positioning groove.

[0016] Preferably, the second positioning part is configured such that a through hole is provided on the main body, and the through hole penetrates the main body in the vertical direction;

[0017] The second positioning part includes a columnar second positioning block, which passes through the perforation of the main body of the wire positioning member from top to bottom and is fixed relative to the main body.

[0018] To facilitate the relative fixation of the second positioning part of the wire positioning part and the metal sheet positioning part, a support groove is also formed on the outer periphery of the through hole of the body. The support groove is formed by the downward indentation of the top of the body. A buckle is formed on the top of the second positioning block. The buckle is supported on the bottom surface of the support groove, thereby fixing the position of the second positioning block relative to the body.

[0019] To facilitate the positioning of the metal sheet and ensure that the metal sheet maintains an upward trend, the second positioning part further includes a second positioning groove formed on the second positioning block. The second positioning groove penetrates the top surface of the second positioning block, and the metal sheet is placed in the second positioning groove. A first elastic element is provided in the second positioning groove to ensure that the metal sheet maintains an upward trend.

[0020] To prevent the metal sheet from being affected by the first elastic element when it is inserted, the second positioning groove passes through one side of the second positioning block. The metal sheet positioning component also includes a stop, which includes a second stop block and a handle. The second stop block is placed in the second positioning groove and can rotate relative to the second positioning block. The metal sheet is supported on the second stop block. The handle is located on the side of the second stop block and extends from the through position of the second positioning groove out of the side of the second positioning block. The first elastic element abuts against the bottom of the second positioning groove and between the second stop block, so that the stop maintains the tendency to push the metal sheet upward out of the second positioning groove.

[0021] Preferably, the side wall of the second positioning block also has a notch, which communicates with the second positioning groove, and the handle of the stop can be inserted into the notch, so that the metal sheet can be inserted without manually pressing the stop.

[0022] To facilitate the movement of the push block, the wire positioning component further includes a first guide portion, which has two parts and is disposed on opposite sides of the body, and the first guide portion extends along a first direction;

[0023] The pusher block also includes a second guide portion that slides in conjunction with the first guide portion.

[0024] To facilitate driving the push block, the manual operation unit includes a pressing part and a transmission part. The pressing part and the bracket are arranged at intervals along a first direction, and the pressing part tends to move away from the bracket.

[0025] The transmission part extends from the pressing part toward the side of the bracket in a first direction, and passes through the bracket and into the push block body, and is detachably connected to the push block body, so that the manual operation part can push the push block to move in the first direction.

[0026] Compared with the prior art, the advantages of this utility model are: by setting the wire positioning component and the metal sheet positioning component, the wire and metal sheet to be assembled can be conveniently positioned, and the metal sheet can be automatically moved into the push block, so that when operating the manual operation part, one metal sheet can be conveniently pushed out and connected to the wire at a time. The structure is simple and the manual operation is simple, which can improve efficiency and save costs. Attached Figure Description

[0034] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions.

[0035] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They 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. Since the embodiments disclosed in this utility model can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0036] See Figures 1 to 7A manual tool for assembling terminals, wherein the terminal to be assembled includes a wire 100 and a metal sheet 200, the wire 100 includes a lead 101 and a connecting portion 102 disposed at the end of the lead 101, and the metal sheet 200 is inserted into the connecting portion 102 to complete the assembly of the terminal.

[0037] The terminal assembly manual tool includes a bracket 1, a wire positioning component 2, a metal plate positioning component 3, a push block 4, and a manual operating part 5. The wire positioning component 2 is fixed to the bracket 1, the metal plate positioning component 3 is fixed to the wire positioning component 2, and the push block 4 is movably disposed on the wire positioning component 2 and the metal plate positioning component 3. The manual operating part 5 is movably connected to the bracket 1 and can move linearly relative to the bracket 1 in a first direction X when pressed, and can reset in the opposite direction to the first direction X. Normally, the first direction X is horizontal.

[0038] The support 1 includes a first frame 11 and a second frame 12, which can be integrally formed. The first frame 11 extends along the second direction Y, and the second frame 12 is located on the side of the first frame 11 away from the manual operation part 5. The aforementioned wire positioning member 2 is connected and fixed to the second frame 12. The first frame 11 can be used by the user to hold during operation.

[0039] The wire positioning component 2 includes an integrally formed body 21, a first positioning part 22, and a first guide part 23. Two first guide parts 23 are provided on opposite sides of the body 21, extending along a first direction X and connected and fixed to the second frame 12 of the bracket 1. A guide groove 231 extending along the first direction X is provided on the first guide part 23. A through hole 211 is provided on the body 21, penetrating the body 21 along a second direction Y. The second direction Y is perpendicular to the first direction X, and normally, the second direction Y is vertically upward. The length of the first guide part 23 along the first direction X can be greater than that of the body 21, meaning the body 21 may not contact or approach the second frame 12. A clearance groove 212 is formed on the wall surface of the body 21 where the through hole 211 is located. The wall surface with the clearance groove 212 is the wall surface of the body 21 closest to the bracket 1. The clearance groove 212 is adapted to the end of the metal sheet 200. Similarly, the clearance groove 212 penetrates the body 21 along the second direction Y. The clearance groove 212 communicates with the through hole 211.

[0040] Along the first direction X, a first positioning part 22 is disposed at the end of the main body 21 away from the second frame 12. The first positioning part 22 includes a first positioning block 221, a first positioning groove 222 formed on the top of the first positioning block 221, and a first stop block 223. The first positioning groove 222 is formed by a downward indentation from the top surface of the first positioning block 221, and extends through the first positioning block 221 along the first direction X. The first positioning groove 222 is at least partially flared 2221, and the larger diameter portion of the flared 2221 is closer to the main body 21 than the smaller diameter portion of the flared 2221. The flared opening 2221 can mate with the connecting portion 102 of the wire 100. During installation, the lead wire 101 of the wire 100 first passes through the opening of the first positioning groove 222 towards the body 21. Pulling the wire 100 along the first direction X allows the lead wire 101 to exit the first positioning groove 222 from the opening away from the body 21. Meanwhile, the connecting portion 102 gradually enters the first positioning groove 222 until it is pulled to abut against the small diameter of the flared opening 2221 and can no longer be pulled. Thus, the first positioning portion 22 defines the position of the wire 100 in the first direction X and in the direction perpendicular to the first direction X (and also perpendicular to the second direction Y). The first stop block 223 is provided on the first positioning groove 222, especially on the flared opening 2221, and can press the connecting portion 102 into the first positioning groove 222 in a direction opposite to the second direction Y. Thus, the wire 100 is stably restrained on the wire positioning member 2.

[0041] The metal sheet positioning member 3 includes a second positioning part 31, a stop member 32, and a first elastic member 33. The second positioning part 31 includes a columnar second positioning block 311, the size and shape of which are adapted to the through hole 211 of the body 21 of the wire positioning member 2. The second positioning block 311 can pass through the through hole 211 of the body 21 of the wire positioning member 2 in a direction opposite to the second direction Y (normally from top to bottom during operation). The body 21 also forms a support groove 213 on the outer periphery of the through hole 211. Preferably, there are two support grooves 213, which are arranged opposite to each other, and each support groove 213 is adjacent to a first guide part 23. The support groove 213 is formed by the downward indentation of the top of the body 21. A buckle 313 is formed on the top of the second positioning block 311, which can be supported on the bottom surface of the support groove 213, thereby defining the position of the second positioning block 311 and preventing it from passing completely downward through the through hole 211. When the installation is complete, the top surface of the second positioning block 311 should not extend upward beyond the top surface of the main body 21; preferably, the two should be flush.

[0042] The second positioning part 31 also includes a second positioning groove 312 formed on the second positioning block 311. The second positioning groove 312 penetrates the top surface of the second positioning block 311 and also penetrates the side of the second positioning block 311 adjacent to the clearance groove 212 of the body 21. The end of the metal sheet 200 can protrude out of the second positioning groove 312. When the height position of the metal sheet 200 in the second direction Y corresponds to that of the body 21, the end of the metal sheet 200 is inserted into the clearance groove 212 of the body 21. The metal sheet 200 is placed in the second positioning groove 312, and is thus restricted by the second positioning groove 312, having only a degree of freedom in the second direction Y.

[0043] The stop member 32 includes a second stop block 321 and a handle 322. The second stop block 321 is placed in the second positioning groove 312 and can rotate relative to the second positioning block 311. The metal sheet 200 is supported on the second stop block 321. The handle 322 is disposed on the side of the second stop block 321 and extends from the through position of the second positioning groove 312 out of the side of the second positioning block 311. The handle 322 is inverted L-shaped. The first elastic member 33 is preferably a spring, disposed in the second positioning groove 312, and abuts against the bottom of the second positioning groove 312 and the second stop block 321, thereby causing the stop member 32 to maintain a tendency to move along the second direction Y (i.e., vertically upward), and thus the stop member 32 maintains a tendency to push the metal sheet 200 out of the second positioning groove 312 along the second direction Y.

[0044] The sidewall of the second positioning block 311 also has a notch 314, which communicates with the second positioning groove 312. When it is necessary to add a metal sheet 200 (stacked from the top of the second positioning groove 312), the stop 32 can be moved to correspond to the notch 314. At this time, by rotating the handle 322, the part of the handle 322 extending perpendicularly to the second direction Y (the part extending laterally in an L shape) is inserted into the notch 314, thereby restricting the position of the stop 32 and preventing it from pushing the metal sheet 200. After the metal sheet 200 has been added, the handle 322 is rotated again to release it from the restriction of the notch 314.

[0045] The push block 4 includes a push block body 41, a second guide portion 42, and an insert 43. The push block body 41 is mounted on the wire positioning member 2 and the metal sheet positioning member 3. Its bottom surface is recessed upward to form a receiving groove 411. The metal sheet 200 corresponds to the position of the receiving groove 411, and the thickness of the metal sheet 200 along the second direction Y of the receiving groove 411 is equal, so that only one metal sheet 200 can enter the receiving groove 411 at any given time. The second guide portion 42 is in the shape of a guide rail and can slide and cooperate with the first guide portion 23 of the wire positioning member 2, thereby guiding the movement of the push block 4 along the first direction X.

[0046] The insert 43 can pass through the push block body 41 so that the push block body 41 and the manual operation unit 5 can be connected, as will be described in detail below.

[0047] The manual operation unit 5 includes a pressing part 51, a second elastic member 52, and a transmission part 53. The shape and extension direction of the pressing part 51 can be adapted to the first frame 11 of the bracket 1 so that the operator can press it during use. The pressing part 51 and the first frame 11 are arranged at intervals along the first direction X. The second elastic member 52 is preferably a spring and abuts between the pressing part 51 and the first frame 11, so that the pressing part 51 tends to stay away from the first frame 11. The transmission part 53 extends from the side of the pressing part 51 toward the first frame 11 along the first direction X and passes through the first frame 11 into the push block body 41. The insert 43 is inserted into the transmission part 53 from top to bottom from the top of the push block body 41, and can then be fixed by fasteners such as screws, thereby completing the detachable connection between the manual operation unit 5 and the push block 4, so that the two can move synchronously in a straight line (feeding along the first direction X and resetting in the opposite direction to the first direction X).

[0048] When assembling the terminals, firstly, a wire 100 is positioned on the wire positioning member 2, and multiple metal pieces 200 are stacked sequentially into the second positioning groove 312 (the push block 4 is removed when placing the metal pieces 200, and the stop member 32 is restricted by the notch 314); the push block 4 is installed so that the receiving groove 411 is aligned with the metal piece 200, and then the restriction of the stop member 32 is released. Under the action of the first elastic member 33, the metal piece 200 is pushed along the second direction Y so that the metal piece 200 at the highest position enters the receiving groove 411 and is higher than the top surface of the body 21 of the wire positioning member 2; then, the manual operation part 5 and the bracket 1 are held, and force (such as by the thumb) is applied to the pressing part 51 of the manual operation part 5 to move it along the first direction X, thereby pushing the push block 4 to move, driving the metal piece 200 located in the receiving groove 411 to be pushed into the connecting part 102 of the wire 100 until it is inserted into the connecting part 102. The assembly is completed when the second elastic member 52 is compressed to its maximum. During the pushing process, since the receiving groove 411 is no longer aligned with the metal piece 200 in the second positioning groove 312, the metal piece 200 is restricted by the bottom surface of the push block body 41 and can no longer be pushed. After that, the pressing part 51 is released, and under the action of the second elastic member 52, the manual operation part 5 drives the push block 4 to reset. At this time, the metal piece 200 in the highest position enters the receiving groove 411, and the subsequent operation is carried out in the same way.
