Conventional technology Conventionally, printed wiring board connectors connect multiple electric wires to a printed wiring board, and relay connectors used to relay connections between various electronic devices via multiple electric wires.
Each was designed as a different type, which was inconvenient in terms of implementation.

Purpose of the Invention The present invention has been made in view of the above points, and an object thereof is to provide an electrical connector that can be used both for connecting electric wires to printed wiring boards and for connecting relay electric wires between various electronic devices. .

Structure of the Invention The electrical connector of the present invention includes a relay connector 2 in which a contact 5 having a contact pin 6 at the front part and a wire connection part 7 at the rear part is housed in an insulating housing 8 separately from each other. , a pin receiving part 12 in which the contact pin 6 fits in the front part;
A contact 11 having a wire connection portion 13 at the rear thereof.
are separately housed in an insulating housing 14 and spaced apart from each other, and both connectors 2
．． and a cylindrical cover body 4 which is fitted and inserted in a state in which the connectors 3 and 3 are connected to each other to cover the entire body. It is characterized in that locking means 27 to 29 are provided.

Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings. The connector 1 of the present invention includes a relay connector 2 for individually connecting a plurality of electric wires 35, a printed wiring board connector 3 for individually connecting a plurality of electric wires 36, and both connectors 2.3.
It consists of a cylindrical cover body 4 which is fitted and inserted in a state of being fitted and connected to cover the entire body.

As shown in FIGS. 4 and 5, the relay connector 2 has a contact pin 6 in the front part and a contact 5 having a wire connection part 7 in the rear part. They are housed separately and separately. Since the wire connection part 7 is of the pressure contact type, there is a wire receiving opening 10 on the wall surface of the housing 8 on the side where the pressure contact piece 7a is located, which extends to the rear end opening.
is provided. Note that the wire connection portion 7 may be of a crimp type.

The printed wiring board connector 3 has a pin receiving part 12 on the front part into which the contact pin 6 of the connector 3 is fitted and connected, and a contact 11 having a wire connecting part 13 on the rear part is located in a hollow part provided in an insulating housing 14. 15 and are housed separately and separately. The wire connecting portion 13 of the contact 11 is also of a pressure contact type, and a wire receiving opening 16 is provided on the wall surface of the housing 14 on the side where the pressure contact piece 13a is located, and extends to the rear end opening. This wire connection portion 13 may also be of a crimp type.

The contacts 5.11 of both connectors 2.3 are formed by punching and bending a conductive metal material such as phosphor bronze,
The housing 8.14 is molded from an insulating plastic material such as nylon.

The upper wall surface of the housing 8 is provided with a protrusion 17 that engages with a locking arm 23 of a cylindrical cover body 4, which will be described later.Furthermore, on both rear sides of the housing 14, engagement recesses that engage with the cylindrical cover body 4 are provided. 18 are provided.

Both connectors 2.3 having the above configuration are electrically connected by fitting the contact pins 6 of the contacts 5 into the pin receiving portions 12 of the contacts 11, as shown in FIGS. 4 and 5. As best shown in FIG. 2, both housings 8.
Engagement protrusions 19 and 20 protruding from both side walls of 14 are engaged and locked together.

The cylindrical cover body 4, as shown in FIGS. 1 to 3,
It is formed into a cylindrical body with a rectangular cross section from an insulating plastic material such as nylon, and is configured to cover the entire body when both connectors 2.3 are fitted and connected as described above. ing. A lock release lever 21 is provided in one opening of the cylindrical cover body 4 so as to be elastically rotatable via a supporting leg 22, and a locking arm 23 is connected to the front end of the lever 21. The locking arm 23 projects inward through an opening 24 provided in the upper wall of the cylindrical cover body 4. On both sides of the cylindrical cover body 4 near the other opening, arms 25 are formed to be elastically movable.
A locking pawl 26.26 is provided at the tip of 25. Further, on both sides of the cylindrical cover body 4, elastic locking wings '27, 27 are provided.
is provided, and a stopper step 2 is provided in the middle of both the upper and lower wall surfaces.
8.28 is provided protrudingly. The elastic locking wing piece 27 is elongated to facilitate elastic deformation and has a shape that protrudes diagonally outward, and a plurality of engagement steps 29 are provided at the tip thereof.

1 and 2, both connectors 2.3 are connected to the cylindrical cover body 4.
An example is shown in which it is used for relay connection between a group of electric wires 35 and a group of electric wires 36 by being inserted into the wire. In use, first, the connector 3 is inserted into the cylindrical cover body 4, and the locking claws 26 are engaged with the engagement recesses 18 on both sides of the housing 14, so that the connector 3 is fixedly held on the cylindrical cover body 4.

In this state, the cylindrical cover body 4 is inserted into the opening 31 provided in the panel 30 of the equipment, and the elastic locking wings 27 and 27 on both sides are elastically deformed to move the engagement step 29 at an appropriate position into the opening 31. By engaging the side edges 32, the cylindrical cover body 4 is fixed to the panel 30.

Thereafter, when the connector 2 is fitted into the cylindrical cover body 4 and connected to the connector 3 as described above, the locking arm 23 of the cylindrical cover body 4 engages with the protrusion 17, and the connector 2 It is fixedly held on the cylindrical cover body 4. At this time, both connectors 2.3 are entirely covered by the cylindrical cover body 4, which can effectively prevent foreign matter from entering from the outside, and
Since the housing 8.14 is locked and held by the cylindrical cover body 4, the fitting connection between the two connectors 2.3 becomes stronger and more reliable, and a highly reliable electrical connection is obtained.

FIG. 6 shows an example in which the connector 3 is used alone to connect the group of electric wires 36 to the printed wiring board 49. In this case, the pin receiving portion 12 of the connector 3 is connected by fitting into a post 41 with a base provided upright on the printed wiring board 40.

Effects of the Invention As described above, according to the present invention, the printed wiring board connector 3 including the contacts 11 having the pin receiving part 12 in the front part and the wire connecting part 13 in the rear part can be connected to a plurality of electrical terminals by itself.
The i36 can be used to connect to a printed wiring board, and if it is combined with the relay connector 2 and inserted into the cylindrical cover body 4, it can be used for relay connections between various electronic devices, so the mounting design is rational. And it becomes easier. Especially when used as a relay, both connectors 2.
Since the entire body 3 is covered with the cylindrical cover body 4, it is possible to reliably prevent foreign matter from entering from the outside.

This is effective when the wire connecting portions 7.13 of both connectors 2.3 are of pressure contact type as in the embodiment. In the pressure welding type, a wire receiving opening 10.16 is provided on the wall of the insulating housing 8.14, and this is because such an opening can be covered, and it is possible to prevent foreign matter from entering from the outside and ensure a reliable wire receiving opening 10.16. Electrical insulation can be maintained. Furthermore, both the connectors 2.3 are held in the cylindrical cover body 4 in a fitted and connected state.

Therefore, the fitting connection between both connectors 2.3 is strong and reliable, and a highly reliable electrical connection can be obtained.
