[Industrial applications]

 The present invention relates to an improvement of a cable connector that can easily and reliably connect two cable connection ends by inserting the two cable connection ends with the connection ends covered.

[0002]

[Prior Art]

 For example, connection of connection cables such as electric wiring drawn out from various electric system parts to electrically connect various electric system parts arranged inside of various equipment and devices such as vehicles. Various cable connection structures have been conventionally proposed for connecting the ends. That is, the easiest way to electrically connect different cable connection ends is to remove the insulation coating from the connection ends of both cables, overlap them and wrap them with insulating tape, or connect them together with screws. Or soldering each to a connecting member. However, such a method requires a troublesome and complicated work for connection, and it is a practical problem especially when it is necessary to sequentially and efficiently connect a large number of cables in a narrow space. It was a big subject.

For this reason, the cable connecting end is inserted into the casing in a covered state, and the cable connecting end is formed on the peripheral edge of the tip of the screw while pressing the cable connecting end with a set screw screwed from the outside. It is conceivable to use a cable connector in which the insulating coating on the cable connection end is cut at the edge so that the cable is cut into the conductive wire side. This will be briefly described with reference to FIG. 6. In the figure, reference numerals 1 and 2 are two cables which are connected to each other, and are shown by 10 in the figure for connecting the cable connection ends 1a and 2a. Such cable connectors are used. This cable connector 10 has cable insertion holes 11 and 11 at both ends and is configured so that the cable connection ends 1a and 2a are inserted in the inside thereof while being covered. With respect to the main body 12, the conductive plate 13 embedded in the main body 12 along the longitudinal direction toward the cable insertion direction, and the screw holes 13a and 13b formed on both end sides of the conductive plate 13. By being screwed in from the outside of the main body 12, it is composed of setscrews 14 and 15 for pressing and locking the cable connection ends 1a and 2a at the tip of the threaded portion. Then, on the end surfaces of the tip ends of the set screws 14 and 15, indentations are formed so that edge portions 16 and 16 are formed in the peripheral edge portions, and these edge portions 16 form the cable connection ends 1a. , 2a are cut to expose the conductive wire portion, and the edge portion 16 bites into the conductive wire to make electrical connection. That is, in this example, the cable connection ends 1a and 2a are electrically connected to each other through the set screw 14 on one side, the conductive plate 13 and the set screw 15 on the other side.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned conventional cable connector 10, in order to electrically connect the two cables 1 and 2, it is necessary to use one having a long connector body 12, which requires a wiring space, a work space, or the like. It was unsuitable when it was necessary to connect the wiring in a short state from the viewpoint of. Furthermore, the above-mentioned conventional structure requires two setscrews 14 and 15 and a conductive plate 13 for connecting two cables, which requires a large number of parts and is troublesome to perform, and has a high contact resistance. There is also a problem in terms of reliability at the connection part, such as a large size, and it is a problem in terms of practical use. Therefore, it is desirable to take some measures to eliminate these problems.

[0005]

[Means for Solving the Problems]

 In order to meet such a demand, the cable connector according to the present invention is inserted in a state in which the cable connection ends are covered when the connection ends of the two cables are mechanically and electrically connected. As a result, the cable connector body is formed internally with holding grooves that hold it from both sides with both cable connection ends held in parallel with each other, and the sharp tip of the screw part can be screwed in from the outside. A single wood screw is provided between the cable connection ends that are held in parallel in the holding groove in a direction substantially orthogonal to each other, and both cable connections are made at the sharp edge of the thread end of the wood screw. By cutting and covering the end coating, both cable connection ends are electrically connected.

[0006]

[Action]

 According to the present invention, the cable connection ends to be connected from the insertion holes provided in the cable connector body are respectively inserted in the state of being covered, and then one from the direction substantially orthogonal to the insertion direction. Screw in the wood screw, and insert the sharp edge of the screw tip between the cable connection ends that are held in parallel from both sides in the main body to cut the coating of the corresponding contact part in order. With this, it is possible to electrically connect and connect both cable connecting ends via this screw part.
