Description

Technical Field

[0001] This application relates to the technical field of electronic wire harness terminal crimping, and in particular to an electronic wire harness terminal crimping device. 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 wire terminals. They are classified into single-hole, double-hole, plug, and hook types, and in terms of materials, they include silver-plated copper, zinc-plated copper, copper, aluminum, and iron. Their main function is to transmit electrical signals or conduct electricity. In the production of electronic wire harnesses, it is often necessary to crimp terminals onto the electronic wire harness using crimping pliers. Currently, most electronic wire harness crimping pliers are handheld, requiring frequent picking up and putting down of the crimping pliers during the crimping process.

[0003] Patent document CN219610961U discloses a terminal crimping device for electronic wire harness processing, which solves the technical problem that while crimping terminals can be performed using crimping pliers, the crimping process requires holding the pliers, making it inconvenient to quickly organize the electronic wire harness. The device includes a base plate and a solid pressure rod. A shaft is connected to one side of the top of the base plate via two upright plates. A sleeve is fitted onto the surface of the shaft, and a sleeve is fixedly connected to the middle of the sleeve via a connecting rod. The connecting rod is connected to one side of the top of the base plate via a support spring. A support plate and a pressure plate are fixedly mounted on the top of the base plate and the surface of the sleeve, respectively. This invention allows the base plate to be placed on a tabletop, eliminating the need for workers to hold it, thus freeing up both hands for organizing the electronic wire harness. The support spring supports the connecting rod, keeping the pressure plate open, facilitating the placement of the electronic wire harness terminals onto any crimping groove on the support plate.

[0004] However, in practical applications, the arc-shaped crimping method described in the aforementioned patent documents can lead to uneven pressure during wire harness crimping, which in turn affects the crimping quality and hinders its widespread use.

[0005] Therefore, those skilled in the art have provided an electronic wire harness terminal crimping device to solve the problems mentioned in the background art. Utility Model Content

[0006] To address the problem that the arc-shaped crimping method mentioned in the background art leads to uneven pressure during wire harness crimping, which in turn affects the crimping quality and hinders its widespread use, this application provides an electronic wire harness terminal crimping device.

[0007] The electronic wire harness terminal crimping device provided in this application adopts the following technical solution: it includes a base plate, a U-shaped frame is fixedly connected to the top side of the base plate, a transmission bracket is slidably connected to the center of the top side of the U-shaped frame, an upper crimping plate is fixedly connected to the bottom end of the transmission bracket, a transmission sleeve is rotatably connected to the top end of the transmission bracket, a transmission rod is slidably contacted on the inner wall of the transmission sleeve, a vertical plate is fixedly connected to the top side of the base plate, the transmission rod is rotatably connected to the top end of the vertical plate, and a lower crimping plate is fixedly connected to the top side of the base plate.

[0008] Preferably, an extension sleeve is slidably fitted onto the outer side of the transmission rod, and an anti-slip sleeve is wrapped around the outer side of the extension sleeve.

[0009] Preferably, the top side of the U-shaped frame has two guide holes, and the inner walls of the two guide holes are slidably fitted with guide rods, and the two guide rods are fixedly connected to the top side of the upper pressing plate.

[0010] Preferably, two counterweights are fixedly connected to the top side of the base plate, and the two counterweights are symmetrically distributed.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] 1. By setting up an upper and lower crimping plate, the wire harness terminals to be crimped are placed on the top side of the lower crimping plate. At this time, the transmission rod is pressed down. When the transmission rod flips downward, it drives the transmission sleeve to move downward. The transmission sleeve drives the transmission bracket to move downward. The transmission bracket drives the upper crimping plate to move downward. At this time, the upper crimping plate gradually approaches the lower crimping plate, and the two cooperate with each other, so that the crimping work can be performed vertically. Compared with the arc-shaped movement crimping method in the comparison document, it can effectively ensure the uniformity of force on the wire harness during crimping, thereby improving the crimping quality and facilitating its widespread use.

[0013] 2. By setting an extension sleeve, the mobility of the extension sleeve during crimping operations can effectively lengthen the lever arm when the transmission rod rotates, thus achieving the purpose of saving effort during crimping by utilizing the lever principle.

[0018] The following will be combined with the appendix Figure 1-3 The technical solution of this utility model has been clearly and completely described. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] This application discloses an electronic wire harness terminal crimping device, referring to... Figure 1-3 The system includes a base plate 1, a U-shaped frame 2 fixedly connected to the top side of the base plate 1, a transmission bracket 3 slidably connected to the center of the top side of the U-shaped frame 2, an upper pressing plate 4 fixedly connected to the bottom end of the transmission bracket 3, a transmission sleeve 5 rotatably connected to the top end of the transmission bracket 3, a transmission rod 6 slidably contacting the inner wall of the transmission sleeve 5, a vertical plate 7 fixedly connected to the top side of the base plate 1, the transmission rod 6 rotatably connected to the top end of the vertical plate 7, and a lower pressing plate 8 fixedly connected to the top side of the base plate 1. By setting the upper pressing plate 4 and the lower pressing plate 8, the wire harness terminals to be pressed are placed... At the top side of the lower pressing plate 8, the transmission rod 6 is pressed down. When the transmission rod 6 flips downward, it drives the transmission sleeve 5 to move downward. The transmission sleeve 5 drives the transmission bracket 3 to move downward. The transmission bracket 3 drives the upper pressing plate 4 to move downward. At this time, the upper pressing plate 4 gradually approaches the lower pressing plate 8, and the two cooperate with each other, so that the pressing work can be carried out in a vertical manner. Compared with the arc-shaped pressing method in the comparative document, it can effectively ensure the uniformity of the force on the wire harness during pressing, thereby improving the pressing quality and facilitating its widespread use.

[0020] In this application, an extension sleeve 9 is slidably sleeved on the outer side of the transmission rod 6, and an anti-slip sleeve is wrapped around the outer side of the extension sleeve 9. By setting the extension sleeve 9, the mobility of the extension sleeve 9 during the crimping operation can effectively lengthen the lever arm when the transmission rod 6 rotates, and by using the lever principle, the purpose of saving effort during crimping can be achieved.

[0021] In this application, two guide holes are provided on the top side of the U-shaped frame 2, and guide rods 10 are slidably sleeved on the inner walls of the two guide holes. The two guide rods 10 are fixedly connected to the top side of the upper pressing plate 4. By setting the guide rods 10, when the upper pressing plate 4 moves, the guide rods 10 cooperate with the guide holes to keep the upper pressing plate 4 moving in a vertical direction and avoid deviation.

[0022] In this application, two counterweights 11 are fixedly connected to the top side of the base plate 1. The two counterweights 11 are symmetrically distributed. By setting the counterweights 11, the two counterweights 11 cooperate with each other during the pressing operation, and their own weight can improve the stability of the overall pressing process.

[0023] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0024] The implementation principle of the electronic wire harness terminal crimping device in this application embodiment is as follows: In use, the wire harness terminal to be crimped is placed on the top side of the lower crimping plate 8. Then, the transmission rod 6 is pressed down. When the transmission rod 6 flips downward, it drives the transmission sleeve 5 to move downward. The transmission sleeve 5 drives the transmission bracket 3 to move downward, and the transmission bracket 3 drives the upper crimping plate 4 to move downward. At this time, the upper crimping plate 4 gradually approaches the lower crimping plate 8, and the two cooperate with each other, thus performing crimping work in a vertical manner. Compared with the arc-shaped crimping method in the prior art, this method... To effectively ensure the uniformity of force on the wire harness during crimping, thereby improving the crimping quality and facilitating its widespread use, the movable nature of the extended sleeve 9 during crimping effectively lengthens the lever arm of the transmission rod 6 during rotation, utilizing the lever principle to achieve the purpose of saving effort during crimping. When the upper crimping plate 4 moves, the guide rod 10 cooperates with the guide hole to keep the upper crimping plate 4 moving vertically and avoid deviation. During crimping, the two counterweights 11 cooperate with each other, using their own weight to improve the overall stability of the crimping process.
