Technical Field

[0001] This utility model relates to the field of terminal bending technology, specifically to an adjustable-angle precision terminal bending fixture. Background Technology

[0002] Switch terminal pins are the interface parts used for wires in electrical connection devices. In some cases, the terminal pins need to be bent when installing and connecting switch terminals.

[0003] Existing technologies lack a structure for precise bending of switch terminal pins at multiple angles, resulting in the need for manual bending or pliers during installation. This bending process is prone to misalignment, altering the pin tip spacing and making it difficult to control the bending angle. To address these shortcomings, this invention presents an adjustable-angle precision terminal bending fixture. Utility Model Content

A bending mechanism includes a bending frame, a bending arc groove, a limiting slider, a bending block, a limiting slide rod, and a handle. Two sets of the bending frames are fixedly connected to the upper surface of the base. The bending arc groove is formed on the bending frame. The limiting slider is slidably disposed in the bending arc groove. The bending block is rotatably connected between the two sets of bending frames. The limiting slide rod is fixedly connected to both sides of the bending block. The handle is fixedly connected to one side of the bending block.

[0006] As a preferred embodiment of this utility model, a lower clamping plate is fixedly connected to one side of the lower fixed seat, a telescopic groove is provided on the upper surface of the lower fixed seat, a limit rod is slidably inserted into the telescopic groove, a spring body is provided inside the telescopic groove, an upper fixed seat is fixedly connected to the top of the limit rod, an upper clamping plate is fixedly connected to one side of the upper fixed seat, a spring buckle plate is provided on one side of the lower fixed seat, and a buckle groove is provided on one side of the upper fixed seat.

[0007] As a preferred embodiment of this utility model, the lower surface of the base is fixedly connected with a support leg.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This adjustable-angle terminal bending fixture releases the clamping mechanism by loosening the knob on the limit slider. Then, the limit slider is slid down along the bending groove to adjust the bending angle of the pin until the indicator arrow on the limit slider points to the corresponding angle scale.

Two sets of bending frames 301 are fixedly connected to the upper surface of the base 1. The bending arc groove 302 is formed on the bending frame 301. The limiting slider 303 is slidably disposed in the bending arc groove 302. The bending block 304 is rotatably connected between the two sets of bending frames 301. The limiting slide rod 305 is fixedly connected to the bending block 304. On both sides of 4, the handle 306 is fixedly connected to one side of the bending block 304. The limiting slider 303 is provided with a knob and a pointer. The knob on the limiting slider 303 can adjust the clamping tightness of the limiting slider 303. The limiting slider 303 is clamped and set on the bending frame 301. An angle scale is provided on the bending frame 301 at the edge of the bending arc groove 302. The limiting slide rod 305 is slidably connected in the bending arc groove 302. The maximum rotation angle of the bending block 304 is limited by the limiting slider 303.

[0019] By setting up a bending frame 301, a bending arc groove 302, and a bending block 304, the rotation axis of the bending block 304 during the rotation process is limited, so that the bending block 304 starts to rotate around the edge where the bending block 304 and the lower clamping plate 201 are connected as the rotation axis to bend the terminal pin. By setting a limiting slider 303, the maximum rotation angle of the bending block 304 is limited, thereby fixing the terminal bending angle.

[0020] Please see Figure 3 A lower clamping plate 201 is fixedly connected to one side of the lower fixed base 2. A telescopic groove 202 is provided on the upper surface of the lower fixed base 2. A limit rod 203 is slidably inserted into the telescopic groove 202. A spring body 204 is provided inside the telescopic groove 202. An upper fixed base 205 is fixedly connected to the top of the limit rod 203. An upper clamping plate 206 is fixedly connected to one side of the upper fixed base 205. A spring buckle plate 207 is provided on one side of the lower fixed base 2. A buckle groove 208 is provided on one side of the upper fixed base 205. The spring body 204 is located at the bottom of the limit rod 203. The spring buckle plate 207 is movably engaged in the buckle groove 208. The lower clamping plate 201 is located on the upper surface of the upper clamping plate 206. The lower fixing seat 2, the lower clamping plate 201, the upper fixing seat 205, and the upper clamping plate 206 are provided to clamp and fix the switch terminal pins. The limiting rod 203 and the spring body 204 are provided so that after the terminal processing is completed, the spring body 204 can use the limiting rod 203 to push the upper clamping plate 206 upward to release the clamping and fixing of the terminal pins. The spring buckle plate 207 and the buckle groove 208 are provided so that the lower clamping plate 201 and the upper clamping plate 206 can quickly lock the clamping and fixing of the terminal pins.

[0021] Working principle: When an adjustable-angle terminal precision bending fixture is used, in the initial state, the lower clamping plate 201, telescopic groove 202, upper fixed seat 205 and upper clamping plate 206 are first set above the base 1. The lower fixed seat 2 and the upper fixed seat 205 are connected by the limiting rod 203 and the spring body 204, and the lower clamping plate 201 and the upper clamping plate 206 are separated. The spring buckle plate 207 and buckle groove 208 set on one side of the lower fixed seat 2 and the upper fixed seat 205 can connect the lower clamping plate 201 and the upper clamping plate 206 to clamp the terminal pin. At the same time, the bending mechanism 3 set behind the lower fixed seat 2 can bend the terminal pin at different angles as needed. When bending the terminal pins at different angles is required, first loosen the knob on the limit slider 303 to release its clamping and fixing. Then, adjust the limit slider 303 by sliding it under the limit of the bending arc groove 302 according to the pin bending angle until the indicator arrow on the limit slider 303 points to the corresponding angle scale. Tighten the knob to lock the position of the limit slider 303. At this time, place the pin of the switch terminal flat on the upper surface of the lower clamping plate 201 and the bending block 304, and press down on the upper fixing seat 205 and the upper clamping plate 206. At the same time, the lower clamping plate 201 and the upper clamping plate 206 clamp and fix the terminal pin, and the spring buckle plate 207 engages. The lower clamping plate 201 and the upper clamping plate 206 are locked and fixed in the corresponding slot 208. Finally, the handle 306 is held and pulled upward to pull the bending block 304. Under the limit of the bending arc groove 302 and the limiting slide rod 305, the bending block 304 starts to rotate with the edge of the connection between the bending block 304 and the lower clamping plate 201 as the rotation axis. At the same time, the rotating bending block 304 pushes the pin that is clamped and fixed above to bend until the bending block 304 rotates and moves upward to contact the limiting slider 303 and is then reset after being limited. This completes the bending of the terminal pin at a fixed angle. This device is convenient for bending the terminal pin at different angles.
