Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a plug for a connector that is attached to the terminal portion of a cord.

[Conventional technology]

It has been common practice in the past to connect cords to each other using connectors.

As the above-mentioned connector, a connector is known in which a plug is inserted into a plug insertion hole formed in a housing, and a terminal provided in the plug is connected to a terminal provided in the housing.

[The problem that the idea aims to solve]

By the way, in conventional connectors, when connecting a plug terminal and a cord, it is necessary to remove the covering of the cord to expose a part of the conductor to the outside. Further, it is necessary to connect the conductor and the terminal through means such as soldering. Therefore, there is an inconvenience that it takes a lot of effort to connect the plug to the cord.

Accordingly, the technical object of this invention is to provide a plug for a connector which eliminates the above-mentioned disadvantages and which can be attached to a cord extremely easily.

[Means to solve the problem]

In order to solve the above problems, this invention has a plug body with a terminal holder section at the tip of the cord holder section, a contact piece by bending one end of the board with the pin hole, and a contact piece with the other end diagonally bent. A pair of electrically conductive terminals are formed by bending the plug body to form an inclined piece, and a cord connecting piece is provided by bending the end of the inclined piece downward. A pair of split plugs are formed by dividing the plug along a plane including the split plugs, and the tips of the split terminal holder portions of the pair of split plugs are connected with a hinge so as to be freely openable and closable.
A connecting pin is provided protrudingly on one side of the dividing surface of the pair of split plugs, and a pin hole into which the connecting pin is press-fitted is provided on the other side, and a pair of terminals are provided on the dividing surface of the split terminal holder portion of the pair of split plugs. A fitting groove is formed, a cord fitting recess is provided on the dividing surface of the split cord holder part, and the
One split plug has a support pin that is inserted into the pin hole of the terminal protruding above the fitting groove, and a housing hole that can accommodate the cord connection piece of the terminal is formed in the split surface of the other split plug. is provided with a pressing surface that presses down the inclined piece of the terminal when assembling the plug body, and the cord connecting piece of the terminal has a circular cord insertion hole, which communicates with the upper side of the cord insertion hole, and the inclined piece presses down. Therefore, a configuration was adopted in which a conductor fitting hole was provided facing on the axis of the cord fitting recess, and the width dimension of the conductor fitting hole was made slightly smaller than the conductor diameter of the cord.

[Effect]

With the above configuration, the pin hole of the terminal is inserted into the support pin, the end portion of the cord is inserted into the cord insertion hole provided in the cord connection piece of the terminal, and the end portion is inserted into the cord fitting recess. When the two split plugs are mated and the other split plug is rotated in a direction that overlaps the one split plug, the other split plug pushes down the inclined piece of the terminal, so that the conductor fitting hole that communicates with the cord insertion hole fits on the outside of the cord. match. At this time, since the width dimension of the conductor fitting hole is almost equal to the conductor diameter of the cord, the cord coating is cut by both side edges of the conductor fitting hole, and the conductor comes into contact with both side edges of the conductor fitting hole. conduction. Therefore, the plug can be easily attached to the cord.

A connecting pin 18 is protruded from one side of the opposing faces of the pair of split plugs 11a and 11b, and a pin hole 19 into which the pin 18 is press-fitted is provided on the other side. By press-fitting the connecting pin 18 into the pin hole 19, the pair of split plugs 11a and 11b are held in an assembled state in which they overlap each other.

In addition, the pair of split plugs 11a and 11b include

It is located on the extension line of

The terminal 30 is accommodated within the terminal fitting groove 20. Here, the terminal 30 is made of a press-molded metal thin plate having conductivity. This terminal 30 is formed by bending one end of a mounting board 32 having a pin hole 31 to form a contact piece 33, and by bending the other end of the mounting board 32 diagonally to provide an inclined piece part 34.
Fold the end of the cord further downward and attach the cord connecting piece 35.
It is said that the configuration includes the following.

Of the pair of split plugs 11a and 11b,
On the other hand, a support pin 22 is provided protruding from the bottom of the terminal fitting groove 20 in the split plug 11a, and the support pin 22 can be press-fitted into the pin hole 31 of the terminal 30. Furthermore, an accommodation hole 23 is provided in the splitting surface of the splitting plug 11a to accommodate the cord connecting piece 35 of the terminal 30.

On the other hand, the split surface of the split plug 11b has a pin receiving hole 24 into which the support pin 22 can be inserted, and a pressing surface 25 that presses down the inclined piece 34 of the terminal 30 supported by the support pin 22 when the plug body 11 is assembled.

In addition, the cord A is fitted into the cord fitting recess 21 of the split plug 11a, and its terminal portion is connected to each terminal 30.
The cord is inserted into the cord insertion hole 36 of the cord. In this state, the other split plug 11b is rotated to overlap the one split plug 11a, and the connecting pin 18 is press-fitted into the pin hole 19 to make the pair of split plugs 11a, 11b
to keep it assembled.

In installing the plug, when the other split plug 11b is rotated toward the one split plug 11a, the pressing surface 25 presses the inclined piece 34 of the terminal 30 downward, so the cord connecting piece 35 moves downward. As the cord connecting piece 35 moves downward, the covering of the cord A is cut by both edges of the conductor fitting hole 37, and the both edges of the conductor fitting hole 37 are connected to the conductor a. The cord A and the terminal 30 are brought into conduction.
