[Detailed description of the device]

[0001]

[Industrial applications]

 The electrical connecting device of the present invention is used for electrical connection between two or more devices and for taking out the power source of the electrical devices in electric wiring for industrial use, household use, etc.

[0002]

[Prior Art]

 Conventionally, there are various types of electrical connectors. As one of them, as shown in FIG. 3, when a rod-shaped pin A is inserted into two leaf spring-shaped receptacles B, the electric wires C and D electrically connected to each other are electrically connected. There are some that are designed to be done. In this electrical connector, dust or oxide film may be attached to the pin A and the receptacle B to deteriorate the conduction. However, rubbing between the two at the time of connection may remove the dust and oxide film to improve the reliability of conduction. Secured. There is also a conventional electrical connector shown in FIG. This is often seen in home electric appliances and the like. When the power plug E attached to the tip of the power cord F is brought close to the receptacle electrode J attached to the appliance body P such as an electric pot, The iron plate provided on the attracted portion L of the plug E is attracted by the magnet K so that the plug electrode G comes into contact with the receptacle electrode J and becomes conductive.

[0003]

[Problems to be solved by the device]

 However, in the plug-in type electrical connector shown in FIG. 3, the pin A and the receptacle B may be damaged unless the pin A is directly inserted into and removed from the receptacle B. Further, since the pin A is sandwiched between the receptacles B, a considerably strong force is required to remove the pin A from the receptacle B, and it is difficult to remove it.

In the electrical connector shown in FIG. 4, unlike the electrical connector shown in FIG. 3, there is no risk of the electrodes being damaged, and a particularly strong force may be required when removing the electrode plug E from the instrument body P. However, since the plug electrode G and the receptacle electrode J are not rubbed at the time of connection, dust and oxide film attached to both electrodes may not be removed, and there is a possibility that contact failure may occur. Further, there is a problem that contact failure is particularly likely to occur when used outdoors where dust is likely to adhere.

[0005]

[The purpose of the device]

 An object of the present invention is to provide an electrical connection device that does not have a possibility of damaging the electrode at the time of attachment / detachment, is easily attached / detached, and is unlikely to cause contact failure due to dust attached to the electrode or an oxide film.

[0006]

[Means for Solving the Problems]

 The electrical connection device of the present invention is an electrical connection device for electrically connecting conductors 8 and 9 connected to respective electrodes 1 and 2 by contact of two electrodes 1 and 2 as shown in FIG. , One electrode 1 is attached to an arbitrary member 3, and the other electrode 2 is slidably attached to another member 4, and the electrode 2 is normally pushed out to the electrode 2 so that the electrode 2 A pushing groove 5 is attached that contracts when pushed by the other electrode 1 and allows the same electrode 2 to retract, and a guide groove that gradually becomes slanted outward from the distal end side of the outer peripheral surface of the same electrode 2 toward the inner side. 6 is formed, and a guide pin 7 is provided in the member 4 so as to be fitted in the guide groove 6 so as to rotate the electrode 2 when the electrode 2 is retracted.

[0007]

[Action]

 In the electrical connection device of the present invention, when the member 4 is pressed against the member 3, the electrode 1 of the member 3 and the electrode 2 of the member 4 come into contact with each other to establish electrical conduction. At this time, when the electrode 2 is pushed by the electrode 1, the guide groove 6 on the outer peripheral surface of the electrode 2 is retracted while being fitted into the guide pin 7 attached to the member 4, so that the electrode 2 is guided by the guide pin 7. The contact surface 2a of the electrode 2 pressed against the electrode 1 is rubbed, and the contact surface 2a and dust and oxide film attached to the electrode 1 are removed. It

【Example】

 In FIG. 1 showing an embodiment of the electrical connecting device of the present invention, reference numeral 1 is an electrode attached to an arbitrary member 3, and a conductor 8 such as an electric wire is connected to the electrode 1. Reference numeral 2 denotes a round rod-shaped electrode, which is slidably arranged in the through hole 4a of the member 4 to the left and right, and is pushed outward (on the left side in the figure) by a pressing spring 5 arranged in the through hole 4a. It projects from the same material 4. In addition, a guide groove 6 is formed on the outer peripheral surface of the electrode 2 so as to be gradually inclined outward from the tip side toward the back side. A guide pin 7 attached to the member 4 is fitted in the guide groove 6. As a result, when the two members 3 and 4 are pressed and the electrodes 1 and 2 are pressed, the electrode 2 rotates while retracting along the guide pin 7. A conductor 9 such as an electric wire is connected to the back surface 2b of the electrode 2. There are various conceivable means for maintaining the connection between the members 3 and 4, but for example, magnets attracting each other may be attached to the members 3 and 4, or mechanically connected.

FIG. 2 shows an example in which the electrical connecting device of the present invention is applied to an interposing manipulator system for new electric wire installation. In FIG. 2, 10 is a gripper body of a slave arm of a master-slave type manipulator, and 11 is two claws provided at the tip of the gripper body. The part 13 is grasped to hold the tool 12. The tool 12 is driven by an electric motor to perform work such as stripping of electric wires. In FIG. 2, the electrical connection device of the present invention is applied to the power supply unit for driving this electric motor.

Reference numeral 2 in FIG. 2 denotes an electrode, which has the same structure as the electrode 2 shown in FIG. An electrode (not shown) having the same structure as the electrode 1 shown in FIG. 1 is attached to the claw 11 facing the electrode 2 shown in FIG. Reference numeral 14 in FIG. 2 denotes a positioning pin, which is provided so that the electrode 2 and the other electrode 1 (not shown) are brought into accurate contact with each other, and are formed at positions facing the positioning pin 14. The two positioning holes 15 are provided so as to be fitted into the positioning holes 15.

[Effect of the device]

 The electrical connecting device of the present invention has the following effects. ． Since the connection between the electrodes 1 and 2 is not a plug-in type, no extraordinarily strong force is required for insertion and removal, and there is little risk that the electrodes 1 and 2 will be damaged during insertion and removal. ． When both electrodes 1 and 2 are connected, one electrode 2 rotates while keeping contact with the other electrode 1 and both electrodes 1 and 2 rub against each other, so that dust and oxide film attached to both electrodes 1 and 2 are removed. Poor contact is less likely to occur.
