Description

Improved Bike Cable

technical field

The present invention relates to an improved cable structure for controlling or actuating a bicycle derailleur or brake caliper.

Background technique

In transportation vehicles such as bicycles, cables are used to move parts (assemblies) such as derailleurs and brake calipers.

As shown in FIGS. 1 and 2 , the brake clip 12 and the cable 30 are part of the brake system 10 . The brake system 10 also includes a support member 20 . The brake clip 12 has two pliers arms 14, and each pliers arm 14 fastens a brake shoe 16, and the brake shoe 16 is located on a side of a wheel 18. The supporting member 20 is fixed on a handle 24 , which is pivotally connected with a brake handle 22 that can swing toward the handle 24 . The cable 30 includes a tube 32 and an inner cable 34 . The inner diameter of the tube 32 is larger than that of the inner cable 34 . The inner cable 34 is inserted into the tube 34 . Therefore, the brake handle 22 drives the inner cable 34 to move in the pipe 32, and drives the pincer arm 14 to clamp the side of the wheel 18 to produce a braking effect.

In addition, China Taiwan Patent No. M475407 discloses some cables 12, 14, 16 and 18. The inner cable 30 is covered with a tube 40. The inner cable 30 has a plurality of core wires 31 and a helical core wire 31. Coil 32 on the outside.

However, the tube itself does not conduct electricity, and the protective inner cable (cable) cannot act as a carrier for power supply or signal transmission. Certain electronic products (such as mobile phones, satellite navigation devices, driving recorders, etc.) or power supplies are used in bicycles, and some additional electric wires or transmission lines are added, which will have a negative impact on driving safety.

Therefore, how to improve the structure of the bicycle cable becomes the problem to be solved urgently by the present invention.

Contents of the invention

The main purpose of the present invention is to increase the efficiency of power supply or signal transmission under the condition that the existing functions of the bicycle cable are not affected, and relatively improve the safety of driving.

In order to achieve the above object, the technical scheme adopted in the present invention is:

An improved bicycle cable is characterized in that it comprises:

a non-conductive pipe;

an inner cable through which both ends are exposed outside the tube; and

At least one conductive material is embedded within the wall of the tube to enable transmission of power or signals.

Wherein, two terminal blocks are also included, and each terminal block is electrically connected to the conductive material.

Wherein, each terminal block includes a box installed on the tube, and a panel inserted into the box and electrically connected to the conductive material.

Wherein, each terminal block is located at the end of the tube.

Among other things, the box includes a large hole to allow the passage of the tube, and a small hole for the inner cable to pass through.

Wherein the tube is made of polymeric material.

Wherein, the polymeric material is polyethylene, polystyrene or polytetrafluoroethylene.

The conductive material referred to here refers to metal wires, metal sheets or other conductive elements used for power supply or signal transmission.

In this way, some electronic products (such as mobile phones, satellite navigation devices, driving recorders, etc.) or power supplies are used in bicycles, and there is no need to add additional wires or transmission lines to avoid affecting driving safety.

detailed description

Please refer to FIG. 3 and FIG. 4 to illustrate the specific structure of a preferred embodiment of the cable 30 . Wherein, the cable 30 has a non-conductive tube 32 and an inner cable 34 , and the inner cable 34 is covered with the tube 32 , so that two ends of the inner cable 34 respectively expose the tube 32 .

The tube 32 is made of non-conductive polymer material, such as polymer polymer such as polyethylene, polystyrene, polytetrafluoroethylene, or other insulators. The tube 32 has a certain tube wall thickness for a plurality of conductive materials 36 to pass through the tube wall and expose two ends of the tube 32 .

The conductive material 36 refers to a metal wire, and the head of the metal wire can be seen on the two ends of the pipe 32 . In some embodiments, the conductive material 36 is a narrow and flat metal sheet or other conductive elements, buried or hidden in the pipe wall.

Two terminal blocks 40 (Terminal Blocks) are electrically connected to corresponding ends of the conductive material 36 . In this embodiment, each terminal block 40 is installed with a panel 42 inside a box 41 .

The box 41 has a pair of holes on the outside, these holes have different diameters. Therefore, one end of the cable 30 enters the box 41 through the large hole 47, and the wall around the small hole 48 blocks the tube 32, but allows the inner cable 34 to extend out of the box 41 through the small hole 48.

There are multiple sockets 43 outside the box 41, and each socket 43 is electrically connected to the panel 42 according to the positive and negative poles. The panel 42 lays circuits according to the electronic circuit layout, and connects the conductive material 36 through at least one pair of leads 49 .

One end of a power line 45 is connected to a power supply (such as a battery), and the other end is inserted into the corresponding socket 43 of the box 41, which can supply the required power of some electronic products, such as mobile phones, satellite navigation devices, and driving recorders.

One end of a signal transmission line 46 is inserted into the corresponding socket 43 of the box 41, and the other end is electrically connected to a radio or MP3 player for audio reception.
