Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector in which a connector body is provided with a terminal shaft for electrically connecting a cable and a cylindrical shaft portion for inserting the cable in the axial direction of the terminal shaft is provided in the terminal shaft. Regarding

[0002]

2. Description of the Related Art Conventionally, in the above connector, as shown in FIG. 9, for example, a terminal shaft 1 is fixed to a first main body member 8A constituting a connector main body 8, and a screw portion S is attached to the first main body member 8A. When the second main body member 8B screwed together is tightened, the second main body member 8B pushes the tightening tool 5 against the cylinder shaft portion 12 of the terminal shaft 1 for screwing, and the tightening tool 5 and the cylinder shaft end. Due to the action of the cam structure provided between the fastener and the action of the slit in the axial direction of the terminal provided on the tubular shaft portion 12, the tightening tool 5 presses the tubular shaft portion 12 so as to reduce the diameter thereof. However, due to the diameter reduction, the cable 9a in which the cylindrical shaft portion 12 is inserted is sandwiched so as to prevent the connection cable from coming off. That is, the removal of the cable is prevented only by the means that is operated by the manual operation of tightening and rotating the second main body member 8B.

[0003]

Conventionally, if there is insufficient operation for tightening during cable connection work, when the cable is subjected to a pull-out operation force due to temperature change, wind pressure, etc., the cable is removed from the terminal shaft. It was relatively easy to pull out and poor conduction or non-conduction was likely to occur. An object of the present invention is to provide a connector in which it is easy to avoid a connection trouble while preventing an increase in connecting work.

[0004]

In order to achieve the object, in the connector according to the present invention, the terminal shaft is attached to the connector body so as to be slidable in the axial direction. A fastening tool for reducing the diameter of the tubular shaft portion while holding the cable between the tubular body portion is manually operably attached to the connector body, and a cam portion acting on the terminal shaft is attached to the connector body and the terminal. Each of the terminal shafts is provided with a contact portion that is pressed against the cam portion as the shaft slides on the cable extraction side with respect to the connector body, and the cylinder is formed by the pressure contact between the cam portion and the contact portion. A cam structure is provided between the cam portion and the abutment portion for reducing the diameter of the cylindrical shaft portion while the shaft portion holds the cable. The action and effect are as follows.

[0005]

[Operation] While inserting the cable into the tubular shaft of the terminal shaft,
When the tightening operation of the tightening tool is performed, the terminal shaft serves as the cylindrical shaft portion and holds the cable, and the cable and the terminal shaft are connected. When the cable is removed and operated, the terminal shaft slides on the cable removal side with respect to the connector body due to friction. Then, the contact portion of the terminal shaft is pressed against the cam portion of the connector body, and due to this pressure contact and the cam structure, the diameter of the cylindrical shaft portion is reduced to automatically clamp the cable, and the action of the tightening tool of the terminal shaft is performed. Even if there is not enough cable holding due to, the cable will not easily come off the terminal shaft regardless of the generation of the cable removal operation force.

[0006]

The cable connection can be maintained by both the holding by the action of the tightening tool and the holding by the action of the cam structure, and the holding by the cam structure is automatically performed. If there is no shortage of operation when tightening the tool, or if there is, and if there is some disconnection operation force such as temperature change or wind on the cable, the connection state Became relatively reliable and reliable. Moreover, with the cam structure's slip-out prevention function, the cable can be configured to work automatically simply by mounting it on the connector body. It has become possible to simplify so that it is only necessary to perform the operation of tightening the tightening tool.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a connector body with a terminal shaft for conducting and connecting a cable, and a cylindrical shaft portion for inserting the cable in the axial direction of the terminal shaft, and The present invention relates to a connector including a connector cover that is fitted onto the connector body.

[0002]

2. Description of the Related Art In this type of connector, if the cable is not sufficiently connected to the terminal shaft, the cable may come out of the terminal shaft when an operation force is applied to the cable due to temperature changes or wind pressure. There is a possibility that it may be pulled out to cause poor continuity or non-conduction. Therefore, conventionally, the connector body is provided with a portion that comes into contact with the end portion of the terminal shaft to prevent its removal, and the removal prevention portion moves the end portion of the terminal shaft in the removal direction. A taper-shaped cam surface was formed so as to press in the diameter reducing direction (see, for example, Japanese Patent Laid-Open No. 61
-See 32976 publication).

[0003]

In the connector having the above-mentioned conventional structure, the terminal shaft is prevented from coming out from the connector body almost completely by the contact with the retaining portion. In addition, the relative movement between the cylindrical shaft portion and the cable inserted into the cylindrical shaft portion is restricted by merely frictional contact, so that it may not be possible to sufficiently prevent the slip-out. In other words, if the terminal shaft tries to move in the direction of pulling out, the cam surface of the retaining portion can be expected to bite the end of the tubular shaft portion of the terminal shaft into the cable. Although it can be regulated, if there is not enough friction between the inner surface of the cylindrical part of the terminal shaft and the outer peripheral surface of the cable inserted into it, only the cable may move and the terminal shaft may not move in the pull-out direction. . Then, unless the connector body and the covering portion of the cable are firmly connected to each other at a place other than the terminal shaft, the terminal shaft and the cable are likely to move relative to each other in the pull-out direction. An object of the present invention is to prevent the terminal shaft from coming out of the connector body and the cable insertion portion from coming out of the terminal shaft with a simple structure, and to prevent the coming-out operation by mounting the connector cover on the connector body. To get a connector that is easy to do in.

[0004]

Means for Solving the Problems The technical means of the present invention taken to achieve the above object is to provide a terminal shaft for conducting and connecting a cable, a connector main body for holding the terminal shaft, and an external fitting to the connector main body. The connector consisting of the connector cover and the following [a] to [d]
It is provided with the configuration described in. [A] The terminal shaft includes a tubular shaft portion into which a cable can be inserted from one end side in a direction along the axis of the terminal shaft. [B] The connector body clamps the outer peripheral surface of the cylinder shaft portion from both outsides at a position on the upper side in the cable pulling-out direction than the end portion on the opening side of the cylinder shaft portion, and reduces the diameter of the cylinder shaft portion. It has a tightening tool that pushes in the direction. [C] The connector body is provided with an annular holder capable of contracting in diameter, which abuts on the end portion of the fastening tool on the radial direction side. [D] The connector cover is formed in a half-split cylinder shape,
A fitting portion is provided for pressing and deforming the annular holder in the diameter reducing direction when the connector holder is externally fitted and mounted.

[0005]

The operation of the above technical means is as follows. a. Connecting the terminal shaft to the connector body and connecting the terminal shaft to the connector body by tightening and fixing the tube shaft portion of the terminal shaft into which the cable is inserted along with the tightening operation of the tightening tool provided on the connector body in the diameter reducing direction. The connection of the cable to the tubular shaft portion of the shaft is performed by operating the tightening tool. b. The tightening tool includes an annular holder capable of reducing the diameter, which is provided in the connector body so as to contact an end portion of the tightening tool on the radial direction side, and a fitting portion for pressing and deforming the annular holder in the diameter reducing direction. With the connector cover equipped with, it can be tightened and moved in the diameter reducing direction, so even if the tightening movement direction of the tightening tool and the external fitting mounting direction of the connector cover do not match, the tightening tool can be reliably reduced in diameter. Can be moved in any direction. That is, when the annular holder is not used, for example, when the connector cover is mounted with the split surface of the connector cover in the shape of a half-split tube being parallel to the moving direction of the tightening tool, the tightening tool will also be attached. Since it is not moved in the diameter reducing direction, the above tightening cannot be performed. On the other hand, according to the present invention, since the annular holder is deformed by reducing the diameter of the annular holder when the connector cover is attached, the tightening tool can be reliably reduced in diameter by the deformation of the annular holder. become. c. Since the connector cover is a half-split cylinder, it has a structure in which a sealing material is attached between the connector cover and the connector body or the outer peripheral surface of the cable in order to enhance the watertightness suitable for outdoor use. Even
External fitting to them can be performed extremely easily as compared with the case of inserting them from the axial direction.

[0006]

The effects of taking the above technical means are as follows. I. The a. From the above effect, it is easy to obtain a reliable retaining structure by restricting both the relative movement of the terminal shaft with respect to the connector body and the cable withdrawal from the terminal shaft. B. The b. Therefore, when mounting the connector cover and performing the tightening operation with the tightening tool, it is necessary to visually check the mounting posture of the connector cover with respect to the tightening tool one by one and perform the tightening operation while maintaining that state. There is an advantage that the tightening operation can be performed easily without being bothered. C. Above a. ~ C. With this function, it is possible to make a reliable connection with the terminal shaft coming out of the connector body and the cable coming out of the tubular shaft portion of the terminal shaft in a controlled state, and the connection work including mounting the connector cover is easy. There is an advantage that various connectors can be obtained.
