Abstract

PURPOSE:To firmly hold a cable, in the case of a connector for fixing the cable to a main body case in form of pressure contact thereto. CONSTITUTION:The tip of a flat type cable 10 is brought in pressure-contact with the upper surface of a connection mount 3 by a pressure-contact member 4 to be electrically connected to a terminal inside of a connector 1. The cable 10 brought in pressure contact is rotated to the upper surface of the pressure- contact member 4, and an auxiliary member 5 is fitted from above. The cable 10 is nipped between the auxiliary member 5 and the pressure-contact member 4 by screwing the auxiliary member 5. Consequently, the anxiety about demounting the auxiliary member 5 is eliminated even if the cable 10 is strongly pulled upward, etc.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector connected to a cable for transmitting data, and more particularly to a connector for fixing a cable by pressing it into a body case.

[0002]

2. Description of the Related Art Conventionally, as a connector attached to a cable for transmitting data, there is one in which the cable is pressed against a body case and fixed.

3A and 3B are views showing the structure of such a conventional connector, in which FIG. 3A is a front view and FIG. 3B is a side view seen from the right side of FIG. The connector 31 is generally case 3
Covered by two. The case 32 includes a slot side case 32a and a rear side case 32b. The tip end portion of the cable 33 is pressure-contacted to the rear side surface 32c of the rear case 32b by the pressure-contact member 34, and each copper wire inside is connected to a terminal (not shown). Both ends of the pressure contact member 34 are fixed to the rear side surface 32c with appropriate strength by fixing members (not shown).

The cable 33, which has its tip end pressed into contact, is passed over the upper surface of the press contact member 34, and the auxiliary member 35 and the press contact member 34.
Sandwiched between. The auxiliary member 35 is connected to the pressure contact member 34 by connecting pins 36 and 37 on both sides.

By sandwiching the cable 33 between the auxiliary member 35 and the pressure contact member 34 in this manner, even if the cable 33 is pulled after being attached, it is held at this portion, so that the cable 33 is connected to the rear side surface 32c. The part is not overpowered.

[0006]

However, the auxiliary member 35 is used.
Since it is connected to the press contact member 34 by the connecting pins 36 and 37, it cannot be said that the strength is sufficient, and there is a possibility that the connecting pins 36 and 37 may come off when a force exceeding a certain level is applied to the cable 33.

Further, since the press contact member 34 and the rear side surface 32c are not fixed sufficiently, even if the connecting pins 36 and 37 are used.
Even if it does not come off, the pressure contact member 34 may come off from the rear side surface 32c together with the auxiliary member 35.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a connector capable of holding a cable more firmly.

[0009]

In order to solve the above-mentioned problems, the present invention provides a connector for fixing a data transfer cable to a main body case in such a manner that a cable is pressed against the case. And an auxiliary member attached to the body case so as to sandwich the cable between the pressure contact member and the pressure contact member.

[0010]

The cable is pressed against the main body case of the connector by the pressure contact member, and the auxiliary member is attached to the main body case so that the cable is sandwiched between the cable and the pressure contact member.

Since the auxiliary member is attached to the main body case, the cable can be held more firmly. Therefore, even if the cable is strongly pulled after installation, there is no concern that it will come off.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 2A and 2B are views showing the configuration of the connector of the present embodiment, where FIG. 2A is a front view and FIG. 2B is a side view of FIG. The connector 1 is generally covered by the case 2.
The case 2 is an integrally formed slot side case 2
It is composed of a and a rear case 2b. A flange 2c is formed at the connecting portion between the slot side case 2a and the rear side case 2b. The left and right ends of the flange 2c are formed to be slightly larger and serve as screw fastening portions 2d and 2e.

A connection stand 3 is provided on the rear surface of the rear case 2b. A flat cable is placed on the upper surface of the connection base 3 while being covered with the flat cable, and is pressed by the pressing member 4. The pressure contact member 4 is fixed to the connection base 3 by a connection piece (not shown). A needle directly connected to the terminal inside the case 2 projects from the upper surface of the connection base 3, and by pressing the cable, the needle breaks through the coating and contacts the copper wire in the cable. This enables electrical and physical connection between the cable and the connector 1.

An auxiliary member 5 is mounted on the pressure contact member 4 with a gap. The auxiliary member 5 is formed in a gate shape and a flat shape, and a protrusion 5a protruding toward the pressure contact member 4 side is press-molded on the ceiling portion thereof.
Both ends of the auxiliary member 5 are fixed to the screw fastening portions 2d and 2e by screws 6 and 7, respectively. In addition, the screw-fastening part 2
Locking members 8 and 9 are screwed together with both ends of the auxiliary member 5 to d and 2e.

FIG. 1 shows a connector 1 having such a structure.
It is a perspective view which shows the state which connected the cable to. The tip end of the flat cable 10 is pressed against the upper surface of the connection base 3 by the pressing member 4 and electrically connected to the terminal inside the connector 1 as described above. The pressure-contacted cable 10 is rotated around the upper surface of the pressure-contact member 4, and the auxiliary member 5 is attached thereto. By fixing the auxiliary member 5 with a screw, the cable 10 is sandwiched between the auxiliary member 5 and the pressure contact member 4. Therefore, even if the cable 10 is strongly pulled upward or the like, there is no concern that the auxiliary member 5 will come off.

As described above, in this embodiment, since the auxiliary member 5 is formed in a gate shape and both ends are fixed to the screwed portions 2d and 2e by screwing, the cable 10 can be easily and surely. Can be fixed.

Further, by screwing the auxiliary member 5 to the case 2 side, the pressure contact member 4 can be pressure contacted together with the cable 10, so that even if an excessive force is applied to the cable 10, the pressure contact member 4 is pressed together. There is no concern that the cable 10 will come off the connection base 3.

Further, in this embodiment, since the auxiliary member 5 is formed in a flat shape, the contact area with the cable 10 can be increased and the frictional force can be increased. Also, because this can reduce the size,
The connector 1 can be used even in a narrow space.

Further, since the protruding portion 5a is formed on the auxiliary member 5, the cable 10 can be clamped more strongly.

[0020]

As described above, according to the present invention, the cable is pressure-contacted to the main body case of the connector by the pressure-contact member, and the auxiliary member is attached to the main-body case by sandwiching the cable with the pressure-contact member. Therefore, the cable can be held more firmly. Therefore, even if the cable is strongly pulled after installation, there is no concern that it will come off.
