Description

Technical Field

[0001] The invention relates to the technical field of cable crimping, in particular to a special cable crimping device. Background Art

[0002] Special cables are also called special-purpose cables or special cables. They are cables designed to meet specific industry, environmental conditions or application requirements. In the actual use of special cables, it is usually necessary to crimp them with terminals and connect the terminals to the working position in the distribution box.

[0003] The existing method of crimping special cables is usually to manually crimp the special cable ends and terminals with handheld electric hydraulic pliers, and then install the crimped special cable ends and terminals together at a designated position in the distribution box.

[0004] Although the above method can quickly crimp the special cable end and the terminal, during the crimping process of the special cable, the operator needs to shape the special cable in advance to facilitate the crimping of the terminal and the special cable end, and ensure that the terminal can be stably moved to the working position in the distribution box after crimping. The operator directly manually bends and shapes the special cable, which is not only time-consuming and labor-intensive, but also requires a high level of strength from the operator. In addition, since the above crimping method includes the step of plugging the special cable end and the terminal, and the special cable end may be uneven, it will not only hinder the insertion of the special cable end into the terminal, but also cause the distance between the inner wall of the terminal and various parts of the special cable end after the insertion is completed to be inconsistent, thereby affecting the crimping effect and the stability of the connection between the special cable end and the terminal after the crimping is completed.

DETAILED DESCRIPTION

[0028] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product specifications are used.

[0029] See also Figure 1-Figure 2 A special cable crimping device includes a main support plate 1, and positioning units 2 are symmetrically installed at the left and right ends of the main support plate 1. The positioning unit 2 is used to install the main support plate 1 in a distribution box at a special cable crimping position. A horizontal slide groove 11 is arranged in the middle of the main support plate 1, and a connecting unit 3 is slidably connected in the horizontal slide groove 11 through a horizontal slider. The connecting unit 3 is provided with a clamping unit 4 for positioning and crimping the special cable.

[0030] The present invention uses the clamping unit 4 to quickly clamp the special cable end and the terminal synchronously to ensure that the two are positioned consistently. After the positioning is completed, the terminal and the special cable end are quickly crimped manually using electric hydraulic pliers. After the terminal crimping is completed, the special cable end and the terminal are simultaneously pushed to the installation position through the connecting unit 3, and the end is installed. In addition, the two positioning units 2 can quickly install the present invention in the distribution box where the cable is installed, thereby facilitating the crimping of the special cable and ensuring the accuracy of the installation position after the crimping is completed.

[0031] Continue reading Figure 1-Figure 2 The positioning unit 2 includes an L-shaped front extension plate 21 fixed on the main support plate 1, an adjusting stud 211 is rotatably installed on the vertical section of the L-shaped front extension plate 21, a matching clamp 212 is threadedly connected to the adjusting stud 211, and the matching clamp 212 is slidably connected to the horizontal section of the L-shaped front extension plate 21; a limiting element 22 for further limiting the connection unit 3 is connected to the right positioning unit 2, the limiting element 22 includes a fixing plate 221 fixed to the top of the horizontal section of the L-shaped front extension plate 21 on the right, and a U-shaped baffle 222 is connected to the rear side of the fixing plate 221 through an elastic telescopic rod.

[0032] The positioning unit 2 on the left is used to abut against the position of the distribution box for installing the trap door, and the positioning unit 2 on the right can support the main support plate 1 by clamping the side wall of the distribution box with the longitudinal section of the L-shaped front extension plate 21 through the positioning clamp 212, so as to adapt to the environment where special cables are crimped in the distribution box. At the same time, since a trap door is usually installed on the left side of the distribution box, the main support plate 1 can be accurately positioned according to the side wall of the distribution box by abutting with the positioning unit 2 on the left and clamping with the positioning unit 2 on the right.

[0033] Specifically, first place the device at the position of the distribution box, and then clamp the right-side positioning clamp 212 and the L-shaped front extension plate 21 at the specified position of the distribution box on the right according to the installation position after the special cable is crimped, and then rotate the right-side adjusting stud 211 so that the right-side positioning clamp 212 and the L-shaped front extension plate 21 cooperate to clamp the distribution box on the right. At this time, due to the abutment of the U-shaped baffle 222 and the right side of the distribution box, the main support plate 1 and the clamping unit 4 are both in a vertical state, and then rotate the left-side adjusting stud 211 to move the left-side positioning clamp 212 toward the left side wall of the distribution box, so that the left and right positioning units 2 cooperate and accurately position the main support plate 1 and the clamping unit 4. At this time, the clamping unit 4 is located directly above the special cable crimping installation position.

[0034] See also Figure 1-Figure 3The connecting unit 3 includes a mounting plate 31 fixed on the front side of the horizontal slider, an adjusting locking element 32 for adjusting the position of the mounting plate 31 is connected between the mounting plate 31 and the main supporting plate 1, an L-shaped connecting plate 311 is fixed at the bottom of the mounting plate 31, and the bottom of the vertical section of the L-shaped connecting plate 311 is connected to a hollow column 312 through a position adjustment structure; the position adjustment structure includes a positioning hole opened on the hollow column 312, and the vertical section of the L-shaped connecting plate 311 is opened with two matching holes, and a positioning pin is connected between the positioning hole and the matching hole at the corresponding position.

[0035] The adjusting locking element 32 includes a vertical plate 321 fixed on the top of the main support plate 1, a matching plate 322 is fixed at the front end of the top of the vertical plate 321, and a plurality of tooth-shaped protrusions 323 are evenly arranged on the bottom of the matching plate 322; a vertical movable plate 324 is connected to the top of the mounting plate 31 through a plurality of vertical springs, and the vertical movable plate 324 is slidably connected to the mounting plate 31 through a plurality of vertical rods 325 sliding through the mounting plate 31, a plurality of tooth-shaped protrusions 323 are also evenly arranged on the top of the vertical movable plate 324, and a handle is fixed on the front side of the vertical movable plate 324.

[0036] The connecting unit 3 is not only used to adjust the left and right positions of the clamping unit 4, but also can adjust the height of the clamping unit 4, so that the end of the crimped terminal can be quickly aligned with the terminal installation position after completion, wherein the adjustment locking element 32 can ensure that the left and right positions of the clamping unit 4 can be quickly adjusted, and ensure the stability of the clamping unit 4 after the adjustment is completed.

[0037] Specifically, after the overall position of the main support plate 1, the connecting unit 3 and the clamping unit 4 is determined, the operator presses down the handle to control the vertical movable plate 324 to move downward and compress the vertical spring, thereby separating the toothed protrusion 323 on the vertical movable plate 324 and the toothed protrusion 323 on the matching plate 322, and then quickly adjusts the position of the mounting plate 31, the L-shaped connecting plate 311 and the hollow column 312 to ensure that the position of the clamping unit 4 is aligned with the position after the special cable is crimped. After the position is determined, the operator releases the handle, at this time, the vertical movable plate 324 will quickly move upward under the action of the vertical spring elastic force and drive the toothed protrusion 323 to clamp with the toothed protrusion 323 on the matching plate 322 again, thereby accurately positioning the positions of the mounting plate 31, the L-shaped connecting plate 311 and the hollow column 312, and fixing the position of the clamping unit 4.

[0038] See also Figure 3-Figure 4 and Figure 7The clamping unit 4 includes a horizontal plate 41 symmetrically fixed at the bottom of the hollow column 312, and a synchronous clamping element 42 for positioning and plugging special cable ends and terminals is commonly connected between the two horizontal plates 41; a limiting column 411 is fixed on the front side of the front horizontal plate 41 and on the right side of the synchronous clamping element 42, and a limiting sleeve 412 is provided on the sliding sleeve of the limiting column 411, and an L-shaped mounting plate 413 is fixed to the rear end of the limiting sleeve 412, and a manual shaping element 43 is provided on the top of the horizontal section of the L-shaped mounting plate 413.

[0039] In this embodiment, if Figure 7 As shown, in order to quickly adjust and fix the position of the manual shaping element 43, it is necessary to set an alignment hole on the limit sleeve 412, two clearance holes are opened on the limit column 411, and a fixing pin is connected between the alignment hole and the clearance hole at the corresponding position.

[0040] The synchronous clamping element 42 can simultaneously position and clamp the special cable end and the terminal, so that the two are precisely aligned, thereby ensuring the stability of the special cable end and the terminal when crimping them, thereby ensuring the quality of the terminal crimping and the stability of the connection between the terminal and the special cable end after crimping. At the same time, the manual shaping element 43 reduces the operator's workload and difficulty in shaping the special cable end.

[0041] Specifically, after the position of the clamping unit 4 is fixed, the special cable end and the terminal are positioned and clamped at the same time by the synchronous clamping element 42 to ensure the concentric positioning of the special cable end and the terminal. After the positioning of the special cable end and the terminal is completed, the operator manually operates the manual shaping element 43 to shape the special cable, so as to avoid the special cable having a large restoring force and causing damage to the installation position of the terminal. Then, the special cable end and the terminal are precisely plugged in. After the two are plugged in, the operator uses an electric hydraulic pliers to quickly crimp the terminal and the special cable end. After the two are crimped, the positioning pin is removed, and the hollow column 312 is made to slide downward along the vertical section of the L-shaped connecting plate 311, thereby driving the clamped terminal and the end to move to the specified position, and then the positioning pin is inserted into the positioning hole and the matching hole at the corresponding position again to ensure the stable installation of the terminal.

[0042] See also Figure 4 , Figure 5 , Figure 6 and Figure 8The synchronous clamping element 42 includes a sliding column 421 that slides symmetrically front and back through the horizontal plate 41, and the ends of the two sliding columns 421 that are close to each other are fixed with end clamps 422; a two-way threaded rod 423 is installed on the two horizontal plates 41 to rotate together, and a crank is fixed on the front end of the two-way threaded rod 423. A horizontal moving plate 424 is connected to the front and rear threads on the two-way threaded rod 423. The horizontal moving plate 424 is fixedly connected to the sliding column 421 at the corresponding position, and a vertical column 425 is fixed at the bottom of the horizontal moving plate 424. A flattening structure and a terminal clamping structure are arranged on the vertical column 425 from top to bottom.

[0043] The straightening structure includes a square sleeve 426 slidably mounted on each vertical column 425, and the opposite sides of the two square sleeves 426 are fixed with straightening claws 427 through connecting rods; a median column 428 is fixed between the two horizontal plates 41, and telescopic spring rods are hinged on the left and right sides of the bottom of the median column 428, and a rotating rod 429 is rotatably installed at the telescopic end of each telescopic spring rod, and the rotating rod 429 is fixedly connected to the straightening claws 427 at the corresponding position.

[0044] The terminal clamping structure includes a connecting sleeve 440 slidably mounted on each vertical column 425, the opposite ends of the two connecting sleeves 440 are connected to terminal clamps 441 through round rods, and the opposite sides of the two terminal clamps 441 are provided with friction rubber pads 442. A square plate 443 is fixed to the bottom of each vertical column 425, and a vertical threaded rod 444 is rotatably installed at the front end of the front connecting sleeve 440, and the vertical threaded rod 444 is threadedly connected to the square plate 443.

[0045] The synchronous clamping element 42 is used to simultaneously position and clamp the special cable end and the terminal. At the same time, the special cable end can be quickly straightened downward through the flattening structure, thereby ensuring that the special cable end and the terminal are accurately positioned concentrically, thereby ensuring that the terminal can be accurately inserted into the special cable end when moving upward, and at the same time ensuring the stability of the special cable end and the terminal during crimping using electric hydraulic pliers and the consistent circumferential distance between the special cable end and the terminal after crimping, thereby ensuring the crimping effect.

[0046] Specifically, after the position of the clamping unit 4 is fixed, the rubber sleeve of the special cable end is first stripped off, and the special cable end portion with the rubber sleeve stripped off is placed at the end clamping jaw 422 position, and then the terminal for crimping is placed between the two terminal clamping jaws 441. Then the operator shakes the handle to rotate the bidirectional threaded rod 423, thereby controlling the two horizontal moving plates 424 to move synchronously, and then controlling the end clamping jaws 422 and the terminal clamping jaws 441 to clamp the special cable end and the terminal at the same time, and ensure that the mounting hole of the terminal is in the positive position. During this process, the straightening claw 427 first moves toward the direction of the special cable end and straightens the special cable end. Then the straightening claw 427 moves downward due to the elastic force of the telescopic spring rod, thereby straightening the special cable end.

[0047] After the straightening claw 427 has straightened the special cable end, the terminal clamp 441 and the clamped terminal are moved upward by rotating the vertical threaded rod 444, and the terminal is sleeved on the outside of the special cable end. At this time, the top of the terminal will press the straightening claw 427 upward, thereby further straightening the special cable end. At the same time, the top of the terminal is pressed by the straightening claw 427, thereby cooperating with the terminal clamp 441 to ensure the stability of the top of the terminal, so as to facilitate crimping. After the terminal is completely sleeved on the special cable end, the operator holds the electric hydraulic pliers and inserts them horizontally between the two vertical columns 425 and crimps the top of the terminal. After the terminal is crimped twice, the vertical threaded rod 444 is controlled to move the terminal clamp 441 downward and away from the terminal, and then another crimp is performed on the terminal at another position, thereby ensuring the connection stability of the terminal and the special cable end after crimping.

[0048] See also Figure 4 , Figure 5 and Figure 7 The manual shaping element 43 includes a sleeve block 431 hinged on the top of the horizontal section of the L-shaped mounting plate 413, an embedded rod 432 is slidably connected in the sleeve block 431, a semicircular stop block 433 is fixed to the end of the embedded rod 432 away from the sleeve block 431, and a track structure is connected between the embedded rod 432 and the L-shaped mounting plate 413; the track structure includes an avoidance groove opened on the front side of the sleeve block 431, a track rod 434 is fixed on the front side of the embedded rod 432 and at a position corresponding to the avoidance groove, a track sleeve 435 is fixed on the top of the horizontal section of the L-shaped mounting plate 413, the track sleeve 435 is located on the front side of the sleeve block 431 and slidably cooperates with the track rod 434, the track sleeve 435 is square and tilted, and a handle is fixed to the front end of the track rod 434.

[0049] A mounting frame 313 is fixed to the right end of the horizontal section of the L-shaped connecting plate 311 . The mounting frame 313 is placed obliquely, and a groove wheel 314 is rotatably mounted on the mounting frame 313 for cooperating with the manual shaping element 43 to shape the special cable.

[0050] The manual shaping element 43 is used to reduce the workload and work intensity of manual shaping of special cables, and cooperates with the groove wheel 314 to effectively shape the special cables. At the same time, the track sleeve 435 cooperates with the track rod 434 to limit the moving track of the semicircular block 433 to ensure that the end of the special cable is stably positioned downward, thereby ensuring the stability of the special cable after clamping. At the same time, the manual shaping element 43 can improve the shaping efficiency of the special cables, thereby reducing the time required for crimping all special cables.

[0051] Specifically, after the straightening claw 427 has straightened the end of the special cable, the operator passes the special cable around the groove wheel 314 and the semicircular stop block 433, and then the operator holds the handle and drives the embedded rod 432 and the outer sleeve block 431 to swing back and forth, so that the track rod 434 drives the embedded rod 432 to move under the limiting action of the track sleeve 435, and then continuously presses the special cable through the semicircular stop block 433, so as to cooperate with the end clamping claw 422 and the groove wheel 314 to shape the special cable, thereby ensuring the stability of the special cable end after crimping, and reducing the stress on the terminal after installation through the shaping of the special cable, thereby improving the strength of the terminal after installation.

[0052] It should be noted that since the manual shaping element 43 can significantly improve the shaping efficiency of special cables, and the special cable ends and terminals can be clamped at the same time through the synchronous clamping element 42, the efficiency will not be reduced during the crimping process of special cables. At the same time, the synchronous clamping element 42 can also improve the convenience of the operator when operating with hand-held electric hydraulic pliers.

[0053] The working steps of the present invention are as follows: the first step is to place the device in the distribution box, and then clamp the positioning unit 2 on the right side at the specified position on the right side of the distribution box according to the installation position after the special cable is crimped, and then rotate the adjustment stud 211 on the left side and move the coordination clamp 212 on the left side toward the left side wall of the distribution box, so that the positioning units 2 on the left and right sides cooperate and accurately position the main support plate 1 and the clamping unit 4. At this time, the clamping unit 4 is located directly above the special cable crimping installation position.

[0054] In the second step, after the overall position of the main support plate 1, the connecting unit 3 and the clamping unit 4 is determined, the operator presses down the handle to control the vertical movable plate 324 to move downward and compress the vertical spring, and then ensures that the position of the clamping unit 4 is aligned with the position after the special cable is crimped by adjusting the locking element 32. After the position is determined, the operator releases the handle. At this time, the positions of the mounting plate 31, the L-shaped connecting plate 311 and the hollow column 312 are precisely positioned, and the position of the clamping unit 4 is fixed.

[0055] In the third step, after the position of the clamping unit 4 is fixed, the special cable end and the terminal are positioned and clamped at the same time by the synchronous clamping element 42 to ensure the concentric positioning of the special cable end and the terminal. After the positioning of the special cable end and the terminal is completed, the operator manually operates the manual shaping element 43 to shape the special cable to avoid the special cable having a large restoring force and affecting the stability of the terminal installation position.

[0056] In the fourth step, after the operator operates the manual shaping element 43 to shape the special cable, the special cable end and the terminal are precisely plugged in. After the two are plugged in, the operator uses electric hydraulic pliers to quickly crimp the terminal and the special cable end. After the two are crimped, the positioning pin is removed, and the hollow column 312 is allowed to slide downward along the vertical section of the L-shaped connecting plate 311, thereby driving the clamped terminal and end to move to the specified position, and then the positioning pin is inserted into the positioning hole and the corresponding position of the matching hole again, and then the terminal is connected and installed with the corresponding position in the distribution box by plugging, thereby completing the crimping of a special cable.

[0057] The fifth step is to repeat the above-mentioned operations of positioning, crimping, shaping and terminal installation of the clamping unit 4, so that all the special cable ends in all distribution boxes are crimped and installed in sequence from right to left.
