Description

Technical Field

[0001] This utility model relates to the field of cable crimping technology, and in particular to a cable connector crimping device. Background Technology

[0002] Cable connectors are key components used to connect, secure, or disconnect cables from equipment. When securing a cable connector to a cable, special tools (such as crimping pliers or hydraulic presses) are needed to apply pressure, causing the connector's metal sleeve to undergo plastic deformation with the cable conductor, forming a gapless contact and reducing contact resistance.

[0003] A mechanical crimping pliers disclosed in Chinese Patent Publication No. CN219717479U features a movable jaw, a return spring, a second limiting block, and a crimping protrusion. The return spring drives the crimping protrusion to reduce the crimping force on the wire, thereby reducing damage to the wire during crimping and protecting it, thus increasing the pliers' protective capabilities. However, according to related technologies and existing technologies, most existing crimping pliers can only effectively crimp cables of specific thicknesses. To handle cables of different diameters, different crimping heads need to be replaced, and the process of replacing the crimping head is time-consuming, affecting overall work efficiency. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a cable connector crimping device.

[0006] Preferably, the crimping assembly includes a mounting box, in which a rotating shaft is rotatably mounted, and a turntable is fixedly mounted on the rotating shaft. The outer surface of the turntable is provided with a plurality of different crimping grooves.

[0007] Preferably, the adjusting assembly includes a worm gear fixed to the rotating shaft, a worm is engaged on one side of the worm gear, the worm is vertically arranged and its two ends pass through the mounting box, and the worm is rotatably connected to the mounting box.

[0009] Preferably, a crimping window is provided through the middle of the pliers head, and the crimping window is located between the two crimping components.

[0010] Preferably, the two corresponding pressing grooves are joined into a regular hexagon when they are joined together.

[0011] Preferably, one end of the worm gear, away from the electric clamp body, extends to the outside of the clamp head and is fixedly equipped with a knob.

[0012] Beneficial effects:

[0013] This cable connector crimping device, through the setting of crimping components, adjustment components, and connection components, features multiple crimping slots of different sizes on the turntable, which can accommodate the crimping of connectors of different sizes. When processing cables of different diameters, there is no need to change different crimping heads, thus improving overall work efficiency.

[0023] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0024] like Figures 1 to 6 As shown, a cable connector crimping device includes an electric clamp body 1, with a clamp head 2 fixedly mounted at the output end of the electric clamp body 1. Two crimping components 4, adapted to various cable models, are symmetrically arranged inside the clamp head 2. The crimping component 4 furthest from the electric clamp body 1 is fixedly connected to the clamp head 2, while the crimping component 4 closest to the electric clamp body 1 is slidably connected to the clamp head 2. Each crimping component 4 has an adjusting component 5 inside for controlling the rotation of the crimping component 4 and switching crimping positions. A connecting component 6 is installed between the two adjusting components 5 for linkage between them. The electric clamp body 1 has a component that extends into the clamp head 2 and pushes the lower crimping component 4 to slide. The output push rod 3 is driven by a crimping window 8 that runs through the middle of the clamp head 2. The crimping window 8 is located between two crimping components 4. The upper adjustment component 5 is connected to the lower adjustment component 5 through the connecting component 6, so that the two crimping components 4 can be rotated and switched to different crimping positions synchronously by the two adjustment components 5 to match the size of the connector to be crimped. Then, the connection between the cable and the connector is extended into the crimping window 8 and placed against the upper crimping component 4. Then, the electric clamp body 1 drives the output push rod 3 to push the lower crimping component 4 to move upward along the inside of the clamp head 2 to crimp the cable and the connector.

[0025] like Figures 3 to 5As shown, the crimping assembly 4 includes a mounting box 41, in which a rotating shaft 44 is rotatably mounted. A turntable 42 is fixedly mounted on the rotating shaft 44. The outer surface of the turntable 42 is provided with multiple different crimping grooves 43. When two corresponding crimping grooves 43 are mated, they are assembled into a regular hexagon. The multiple crimping grooves 43 of different sizes provided on the turntable 42 can be switched by adjusting the rotating assembly 5 to control the rotation of the turntable 42 around the rotating shaft 44, thereby adapting to the crimping of connectors of different sizes and improving the applicability of the device.

[0026] like Figures 3 to 5 As shown, the adjustment assembly 5 includes a worm gear 51 fixed on the rotating shaft 44. A worm 52 is engaged on one side of the worm gear 51. The worm 52 is vertically arranged and its two ends pass through the mounting box 41. The worm 52 is rotatably connected to the mounting box 41. One end of the worm 51 away from the electric clamp body 1 extends to the outside of the clamp head 2 and is fixedly provided with a knob 7. By rotating the worm 52 through the knob 7, the worm 52 engages with the two worm gears 51 respectively, driving the corresponding turntable 42 to rotate around the rotating shaft 44, switching the crimping groove 43 on the turntable 42 to match the size of the crimped connector.

[0027] like Figures 3 to 6 As shown, the connecting assembly 6 includes a spline sleeve 61, inside which a spline shaft 62 is slidably mounted. The spline sleeve 61 is fixedly connected to a worm 51 away from the electric clamp body 1, and the spline shaft 62 is fixedly connected to a worm 52 close to the electric clamp body 1. The spline shaft 62 and the spline sleeve 61 connect the two worms 52. During the crimping process, the spline shaft 62 slides into the spline sleeve 61 to ensure that the crimping can proceed normally. During adjustment, the upper worm 52 is rotated by the knob 7, causing it to drive the lower worm 52 to rotate synchronously through the spline sleeve 61 and the spline shaft 62. The two worms 52 then mesh with two worm wheels 51 respectively, driving the corresponding turntables 42 to rotate around the shaft 44, synchronously switching the crimping grooves 43 on the two turntables 42. The switching operation is simple, saves time and effort, and improves work efficiency.

[0028] The work process is as follows:

[0029] S1: As Figure 5 As shown, the multiple crimping grooves 43 of different sizes provided on the turntable 42 can adapt to the crimping of connectors of different sizes, thereby improving the applicability of the device;

[0030] S2: As Figure 6 As shown, during use, the upper worm gear 52 is rotated by knob 7, which causes the lower worm gear 52 to rotate synchronously through spline sleeve 61 and spline shaft 62;

[0031] S3: As Figure 3 and Figure 4As shown, the two worm gears 52 respectively mesh with the two worm wheels 51, driving the corresponding turntables 42 to rotate around the shaft 44, and synchronously switching the crimping grooves 43 on the two turntables 42 to match the size of the connector being crimped.

[0032] S4: As Figure 3 As shown, the connection between the cable and the connector is then extended into the crimping window 8 and placed against the crimping groove 43 above.

[0033] S5: As Figure 4 As shown, the electric clamp body 1 then drives the output push rod 3 to push the mounting box 41 below along the inside of the clamp head 2, causing the turntable 42 to move upward, so that the two crimping grooves 43 are connected to crimp the cable and connector.

[0034] The electric clamp body 1 in this application is a well-known technology in this field, therefore its specific structure and working principle are not described in detail.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
