Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a quick connector for preventing loosening of cables. Background Technology

[0002] Automotive cables are steel wire ropes composed of an outer protective cable, primarily used to stabilize steel structural components or tensioned membrane structures. As crucial components of the automotive transmission system, they include core components such as steel strands, cable anchors, and cable ends, and are used in braking, accelerator, gear shifting, clutch operation, and seat adjustment. Functionally, they are categorized into accelerator cables, clutch cables, brake cables, seat cables, and parking cables, adapting to different vehicle models through length variations and ball-end fasteners. Their development is trending towards lightweight, high precision, and long lifespan. Brake cable connectors, often called balancers, adjusters, or connecting forks, are a critical yet often overlooked small component in mechanical brake cable systems.

[0003] The most important function of the connector is to distribute the tension of the self-operated cable fairly and synchronously to the two output cables, ensuring that the brakes on both sides (usually the rear wheel brakes) can work simultaneously and with equal force, preventing the vehicle from veering off course when the handbrake is engaged. It can also fine-tune the effective length of the cable and change the traction direction, thereby eliminating excessive free travel caused by slack and ensuring the effectiveness of the handbrake or foot brake. When the brake cable lacks preload, the cable end can easily detach from the connector's mounting slot. Since the connector is usually located under the vehicle body, this detachment is not easily detected, increasing safety hazards. Therefore, a quick-connect cable connector with anti-loosening feature is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fast cable connector that prevents loosening.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A quick-connect cable with anti-loosening features a U-shaped cover. A parking cable is inserted into the middle of one end of the U-shaped cover, and a fixing wire head is fixedly installed at the end of the parking cable. Notches are provided on both sides of the outer wall of one end of the U-shaped cover. Through holes are provided in the middle of the top and bottom of the U-shaped cover, and positioning rods are inserted between the middle of the fixing wire head and the two through holes. Right-angle openings are provided in the middle of the upper and lower ends of the outer walls on both sides of the U-shaped cover, and a cable head is slidably provided inside each right-angle opening. An M-shaped piece is placed on the top of the U-shaped cover. A U-shaped seat is fixedly installed in the middle of the opening end of the U-shaped cover. A drive shaft is rotatably installed in the middle of the U-shaped seat, and a transmission gear is fixedly installed inside the drive shaft. A U-shaped support is fixedly installed inside the U-shaped seat, and a first L-shaped rack and a second L-shaped rack are slidably sleeved on the top and bottom of the U-shaped support, respectively. The circumference of the transmission gear meshes with the horizontal sections of the first and second L-shaped racks, and compression sleeves are fixedly installed on the vertical sections of the first and second L-shaped racks.

[0006] Preferably, the positioning rod has a first thread in the middle of its circumference, a second thread at the bottom of its circumference, and a positioning nut is rotatably sleeved at the bottom of its circumference.

[0007] Preferably, the top and bottom ends of the cable head are fixedly connected to limit caps, and the limit caps are located on the outer side of the outer wall of the U-shaped cap. The cable body is fixedly installed in the middle of the circumference of the cable head.

[0008] Preferably, the M-shaped piece has a through hole in the middle, and the width of the M-shaped piece is greater than the width of the right-angle opening.

[0009] Preferably, a rotating sleeve is fixedly sleeved on the outer circumference of the drive shaft, and the outer circumference of the rotating sleeve is provided with anti-slip ridges. The outer end of the drive shaft is provided with a third thread, and a locking nut is sleeved on the outer circumference of the drive shaft.

[0010] Preferably, the extrusion sleeve includes a base plate, and a card holder is fixedly connected to the outer side of the base plate, with the card holder having an arc shape in the middle.

[0011] The beneficial effects of this utility model are as follows: This utility model proposes a quick-connect connector for a parking cable that prevents loosening. First, the parking cable is slidably inserted into the U-shaped cover. The cable head is slidably sleeved onto the ends of two right-angle openings on the same side. Next, an M-shaped piece is placed on the top of the U-shaped cover, with the through hole and the perforation aligned. The two ends of the M-shaped piece press against the limiting caps at the top of the two cable heads. Then, a positioning rod is inserted sequentially into the through hole of the M-shaped piece, the perforation at the top of the U-shaped cover, and the upper end of the fixed cable head. The positioning rod is rotated until its second thread is located on the outside of the U-shaped cover. Then, the positioning nut is rotated and sleeved onto the bottom circumference of the positioning rod to quickly connect and install the brake cable. Next, the rotating sleeve is rotated to make the drive shaft rotate, causing the transmission gear to drive the first L-shaped rack and the second L-shaped rack to move. The two compression sleeves move away from each other until they are engaged with the circumference of the cable head. Then, the locking nut is rotated to fix the rotating sleeve between the outer wall of the U-shaped seat and the locking nut. The drive shaft and the transmission gear are locked, thereby achieving the effect of keeping the compression sleeves pressing against the cable head, effectively preventing the cable head from detaching from the inside of the right-angle opening.

Detailed Implementation

[0014] Reference Figure 1-5A quick-connector for preventing loosening of a cable includes a U-shaped cover 1. A parking cable 2 is inserted into the middle of one end of the U-shaped cover 1, and a fixing wire head 3 is fixedly installed at the end of the parking cable 2. Notches 4 are provided on both sides of the outer wall of one end of the U-shaped cover 1. Through holes 5 are provided in the middle of the top and bottom ends of the U-shaped cover 1, and positioning rods 6 are inserted between the middle of the fixing wire head 3 and the two through holes 5. Right-angle openings 7 are provided in the middle of the top and bottom ends of the outer walls on both sides of the U-shaped cover 1, and a cable head 8 is slidably provided inside each right-angle opening 7. An M-shaped piece 11 is placed on the top of the U-shaped cover 1. A U-shaped seat 13 is fixedly installed in the middle of the opening end of the cover 1. A drive shaft 14 is rotatably installed in the middle of the U-shaped seat 13. A transmission gear 17 is fixedly installed inside the drive shaft 14. A U-shaped support 18 is fixedly installed inside the U-shaped seat 13. A first L-shaped rack 19 and a second L-shaped rack 20 are slidably sleeved at the top and bottom of the U-shaped support 18, respectively. The circumference of the transmission gear 17 meshes with the horizontal section of the first L-shaped rack 19 and the second L-shaped rack 20. A compression sleeve 21 is fixedly installed on the vertical section of both the first L-shaped rack 19 and the second L-shaped rack 20.

[0015] In this utility model, the positioning rod 6 has a first thread 22 in the middle of its circumference and a second thread 23 at the bottom of its circumference. The bottom of the positioning rod 6 is rotatably sleeved with a positioning nut. The positioning rod 6 is inserted into the through hole 12 of the M-shaped piece 11, the through hole 5 at the top of the U-shaped cover 1, and the upper end of the fixing wire head 3 in sequence. Then, the positioning rod 6 is rotated until its second thread 23 is located on the outside of the U-shaped cover 1. The positioning nut is then rotated and sleeved on the bottom of the positioning rod 6 to achieve the effect of fixing the parking cable 2 inside the U-shaped cover 1. The top and bottom ends of the cable head 8 are fixedly connected to the limiting caps 10, and the limiting caps 10 are located on the outer side of the outer wall of the U-shaped cap 1, so that the cable head 8 of the cable body 9 can be quickly put on along the right-angle opening 7. The cable body 9 is fixedly installed in the middle of the circumference of the cable head 8. The M-shaped piece 11 has a through hole 12 in the middle. The width of the M-shaped piece 11 is greater than the width of the right-angle opening 7. When the M-shaped piece 11 is positioned by the positioning rod 6, the two ends of the M-shaped piece 11 press against the limiting caps 10 at the top of the two cable heads 8, further restricting the cable heads 8 from sliding inside the right-angle opening 7. A rotating sleeve 15 is fixedly sleeved on the outer circumference of the drive shaft 14, and the outer circumference of the rotating sleeve 15 is provided with anti-slip ridges. The outer end of the drive shaft 14 is provided with a third thread, and a locking nut 16 is sleeved on the outer circumference of the drive shaft 14. By rotating the rotating sleeve 15, the drive shaft 14 can be rotated, which in turn causes the transmission gear 17 to drive the first L-shaped rack 19 and the second L-shaped rack 20 to move. The two pressing sleeves 21 move away from each other until they engage with the circumference of the cable head 8. Then, the locking nut 16 is rotated to fix the rotating sleeve 15 between the outer wall of the U-shaped seat 13 and the locking nut 16. The drive shaft 14 and the transmission gear 17 are both locked, thereby achieving the effect of keeping the pressing sleeve 21 pressing the cable head 8 at all times. The extrusion sleeve 21 includes a base plate, and a card holder is fixedly connected to the outside of the base plate. The card holder is arc-shaped in the middle, so that the extrusion sleeve 21 fits the circumference of the cable head 8 with a larger area.

[0016] Working principle: First, slide the parking cable 2 into the U-shaped cover 1. The cable head 8 of the cable body 9 slides onto the ends of the two right-angle openings 7 on the same side. Then, lay the M-shaped piece 11 on the top of the U-shaped cover 1, aligning the through hole 12 with the through hole 5. The two ends of the M-shaped piece 11 press against the limiting caps 10 at the top of the two cable heads 8. Next, insert the positioning rod 6 into the through hole 12 of the M-shaped piece 11, the through hole 5 at the top of the U-shaped cover 1, and the upper end of the fixing cable head 3 in sequence. Rotate the positioning rod 6 until its second thread 23 is located on the outside of the U-shaped cover 1. Then, rotate the positioning nut onto the fixing cable head 3. At the bottom of the circumference of the insertion rod 6, the brake cable is quickly connected and installed. Then, the rotating sleeve 15 is rotated to make the drive shaft 14 rotate, which causes the transmission gear 17 to drive the first L-shaped rack 19 and the second L-shaped rack 20 to move. The two compression sleeves 21 move away from each other until they are engaged with the circumference of the cable head 8. Then, the locking nut 16 is rotated to fix the rotating sleeve 15 between the outer wall of the U-shaped seat 13 and the locking nut 16. The drive shaft 14 and the transmission gear 17 are locked, thereby achieving the effect of keeping the compression sleeve 21 pressing the cable head 8 at all times, effectively preventing the cable head 8 from coming out of the right-angle opening 7.
