Description

Technical Field

[0001] This utility model belongs to the field of automotive cable structure installation technology, and in particular relates to an automotive cable connector press-fitting device. Background Technology

[0002] Automotive cables are cables used extensively in automobiles for signal transmission, such as the high-voltage wires used in vehicles. During the manufacturing process of automotive cables, connectors, or cable connector terminals, need to be crimped onto the cable ends. These connectors are cap-shaped, and crimping them onto the cable facilitates subsequent installation.

[0003] Because the connector (made of metal) is relatively small, the pressing process is quite difficult. In existing technology, the connector is pre-sleeved onto the end of the cable, and then the cable with the connector attached is fed into the pressing mold for pressing.

[0004] However, in actual operation, due to the certain length of the cable and the very small diameter of the cable and connector, it is difficult to put the material into the mold. Specifically, the small diameter cable and connector are difficult to align into the mold. Secondly, the pressing operation is difficult, specifically because the connector is too small and difficult to position.

[0005] Therefore, while the existing technology of using handheld crimping pliers can greatly improve the flexibility of operation, it is relatively inefficient. This is because the connector needs to be aligned with the slot inside the pliers and the position needs to be accurate. Otherwise, after crimping, the cable may not make sufficient contact with the connector, resulting in poor contact during use.

[0006] Therefore, for cables and connectors that are small in size and difficult to press, it is crucial to improve pressing efficiency by using a pressing device that is simple to operate and has high pressing efficiency. Utility Model Content

[0007] Based on the above background, the purpose of this utility model is to provide an automotive cable connector pressing device.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A crimping device for automotive cable connectors includes several crimping units for crimping cable connectors; each crimping unit includes a locking sleeve, and a limiting seat for limiting cables is slidably connected inside the locking sleeve.

[0010] The limit seat has limit holes for limit connectors and cables;

[0011] The locking unit also includes a driving structure for driving the limit seat to slide into the locking sleeve. During the process of the limit seat sliding into the locking sleeve, the connector is locked to the end of the cable by the locking structure between the locking sleeve and the limit seat.

[0012] The limit seat is fixedly connected to a lead tube that connects to the limit through hole, and several cable guide structures are installed at the feed inlet of the lead tube.

[0013] Preferably, the locking structure includes a plurality of locking protrusions disposed within the locking sleeve, each locking protrusion including a ramp portion, the ramp portion having an integrally formed locking portion of a locking connector;

[0014] The locking structure also includes several locking through slots formed on the limiting seat, which are connected to the limiting through holes;

[0015] As the limit seat enters the locking sleeve, the depth of the locking protrusion extending into the locking through groove increases.

[0016] Preferably, the locking sleeve is fixedly connected to an inner fixing seat, and the locking protrusion is fixedly connected to one side wall of the inner fixing seat.

[0017] Preferably, the driving structure includes a cylinder fixedly connected to the side wall of the inner fixed stop, the piston rod of the cylinder being fixedly connected to a driving connecting seat, and a plurality of driving rods slidably connected to the inner fixed stop being fixedly connected to the driving connecting seat, the outer ends of the driving rods being fixedly mounted on a limiting seat.

[0018] Preferably, a spring is sleeved on the drive rod, and the two ends of the spring are respectively fixedly connected to the inner fixed stop and the drive connecting seat.

[0019] Preferably, the automotive cable connector pressing device further includes a working platform, and the bottom of the locking sleeve is fixedly connected to a mounting base fixedly installed at the top position of the working platform.

[0020] Preferably, the cable guiding structure includes a plurality of guide wheels, each with a guide groove, through which the cable is guided and threaded.

[0021] Preferably, the guide wheel is equipped with a wheel frame structure, which is fixedly installed on the outer side wall of the lead tube.

[0022] Preferably, the longitudinal interface shape of the locking sleeve and the limiting seat is circular.

[0023] This utility model has the following beneficial effects:

[0024] 1. During operation, as the limiting seat enters the locking sleeve (the connector and cable inside the limiting seat enter the locking sleeve simultaneously), the depth of the locking protrusions into the locking grooves increases. Simultaneously, the four locking protrusions gradually press against the connector, and as the limiting seat enters the locking sleeve deeper, the clamping force of the locking protrusions gradually increases until locking is completed at the locking section. After locking, four pressure grooves are formed on the connector, effectively locking the cable in place.

[0025] The above method not only greatly reduces the difficulty of crimping small connectors, but also cleverly uses a crimping structure to crimp the connector and cable in the limited state, which greatly improves the crimping efficiency and processing efficiency.

[0026] 2. During operation, driven by the cylinder, the drive connecting seat moves rearward, pulling the drive rod into the locking sleeve for locking. After locking, the limit seat quickly disengages from the locking sleeve due to the elastic restoring force of the spring, facilitating material unloading. This method achieves automatic cylinder-driven locking, further improving processing efficiency.

[0027] 3. The cable guiding structure includes four circumferentially arrayed guide wheels, each with a guide groove. The cable is guided through the grooves between the guide wheels. Specifically, a limiting passage gap is formed between the guide grooves of the four guide wheels, through which the cable passes. During cable feeding, the guide wheels rotate, achieving the limiting function while preventing damage to the cable sheath. This method ensures the cable accurately enters the limiting seat during the feeding process. Attached Figure Description

[0040] Example 1

[0041] like Figure 1-7 As shown, an automotive cable connector crimping device includes several crimping units 2 for crimping cable connectors; during operation, each crimping unit 2 processes one cable b.

[0042] Specifically, the automotive cable connector pressing device also includes a working platform 1, and the bottom of the locking sleeve on the pressing unit 2 is fixedly connected to a mounting base 211 fixedly installed at the top of the working platform 1.

[0043] The aforementioned locking unit 2 includes a locking sleeve 21, within which a limiting seat 3 for the limiting cable b is slidably connected; the longitudinal interface shapes of the locking sleeve 21 and the limiting seat 3 are all circular. A cavity is provided on the locking sleeve 21 for slidably connecting the limiting seat 3.

[0044] Furthermore, a limiting through hole 331 for limiting connector a and cable b is provided at the center of the limiting seat 3. During the processing, connector a is pre-inserted into cable b and extends into the limiting through hole 331. Under the limitation of the limiting through hole 331, connector a and cable b remain in the limited state.

[0045] In order to achieve locking, the locking structure between the locking sleeve 21 and the limiting seat 3 locks the connector a to the end of the cable b.

[0046] Specifically, the locking structure includes four circumferentially arrayed locking protrusions 25 disposed within the locking sleeve 21. The locking protrusions 25 include a ramp portion 251 (the longitudinal cross-sectional shape of the ramp portion 251 is triangular, and its bottom is a ramp surface). At the same time, the ramp portion 251 is integrally formed with a locking portion 252 of the locking connector a; the longitudinal cross-sectional shape of the locking portion 252 is rectangular.

[0047] The aforementioned locking structure also includes four locking through slots 33 formed on the limiting seat 3, which connect to the limiting through hole 331. The locking through slots 33 are L-shaped.

[0048] During operation, as the limiting seat 3 enters the locking sleeve 21 (with connector a and cable b simultaneously entering the locking sleeve 21), the depth of the locking protrusions 25 extending into the locking grooves 33 increases. Simultaneously, as the four locking protrusions 25 gradually press against connector a, and as the depth of the limiting seat 3 entering the locking sleeve 21 increases, the clamping force of the locking protrusions 25 gradually increases until locking is completed at the locking section. After locking, four pressure grooves are formed on connector a, thus locking connector a to cable b.

[0049] The above method not only greatly reduces the difficulty of locking the small connector a, but also cleverly uses a locking structure to lock the connector a and cable b in the limited state, which greatly improves the locking efficiency and the processing efficiency.

[0050] Example 2

[0051] like Figure 1-7 As shown, based on the structure of Embodiment 1, the above-mentioned locking unit 2 further includes a driving structure for driving the limiting seat 3 to slide into the locking sleeve 21.

[0052] Specifically, an inner fixing seat is fixedly connected inside the locking sleeve 21, and a locking protrusion 25 is fixedly connected to the front side wall of the inner fixing seat. Meanwhile, the drive structure includes a cylinder 22 fixedly connected to the rear side wall of the inner fixing seat. The piston rod of the cylinder 22 is fixedly connected to a drive connecting seat 23. Two drive rods 24, which are slidably connected to the inner fixing seat, are fixedly connected to the drive connecting seat 23. The outer ends of the drive rods 24 are fixedly mounted on the limiting seat 3.

[0053] Meanwhile, a spring 241 is sleeved on the drive rod 24, and the two ends of the spring 241 are fixedly connected to the inner fixed stop and the drive connecting seat 23 respectively.

[0054] During operation, driven by cylinder 22, drive connecting seat 23 moves rearward and drives drive rod 24 to pull limit seat 3 into locking sleeve 21 for locking. After locking, the limit seat 3 quickly disengages from locking sleeve 21 under the elastic restoring force of spring 241, facilitating unloading. This method achieves automatic driving locking by cylinder 22 structure, further improving processing efficiency.

[0055] Example 3

[0056] like Figure 1-7 As shown, in this embodiment, based on the structure of embodiment 1, a lead tube 31 with a through hole 331 is fixedly connected to the limiting seat 3, and several cable guide structures 32 are installed at the feed inlet of the lead tube 31.

[0057] The cable is easily guided into the limiting seat 3 by the lead tube 31 and the cable guide structure 32, which increases the efficiency of feeding.

[0058] Specifically, the cable guiding structure 32 includes four circumferentially arrayed guide wheels 322, each with a guide groove A. The cable b is threaded through the guide grooves A of the guide wheels 322. That is, a limiting passage gap is formed between the guide grooves A of the four guide wheels 322, and the cable b passes through the limiting passage gap. During the pushing of the cable b, the guide wheels 322 rotate, achieving limiting while avoiding scratching the surface of the cable b (specifically, the rolling friction is low).

[0059] The aforementioned guide wheel 322 is equipped with a wheel frame structure (the wheel frame structure is an L-shaped wheel frame arm 321), and the wheel frame arm 321 is fixedly installed on the outer wall of the lead tube 31 by bolts 3211.

[0060] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
