DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector and a terminal connected to the connector, and more particularly, to a connector provided with a connector terminal that protrudes from the inside of a connector body to the outside and is connected to a terminal of an electric wire, and a connector connected to the connector. Related terminals.

[0002]

2. Description of the Related Art A wire harness composed of a plurality of electric wires is designed to be attached to an electrical component via a connector, and a terminal of an electric wire constituting the wire harness is mounted as this type of connector. Some connector terminals are exposed outside the connector body.

[0003] As a connector of this type, there is a connector mounted on a printed circuit board. In this connector, a large number of connector terminals are soldered to the printed circuit board.

[0004] Since this type of connector has a large number of connector terminals, a wire harness is connected to the connector terminals to measure the evaluation characteristics of the engine and electronic equipment in order to perform an evaluation test of the engine and electronic equipment of the vehicle. Suitable to do.

As a conventional connector of this type, for example, there is one shown in FIG. In FIG. 3, reference numeral 1 denotes a connector of a type usually mounted on a printed circuit board. The connector 1 includes a connector body 2 and a plurality of upper and lower two-stage L-shaped connectors projecting from the inside of the connector body 2. The connector terminal 3 is connected to a terminal 4a of an electric wire 4 constituting a wire harness. The reason why the connector terminal 3 is formed in an L-shape is that it is usually soldered to a printed board (not shown).

In order to attach the electric wire 4 to the connector 1 having such a configuration, the connector terminal 3 is straightened as shown in FIG. 4 (a), and then the connector terminal 3 is made uniform in order to make the length of the connector terminal 3 uniform. 3 is cut to a length of about 10 mm from the surface of the connector main body 2 (see FIG. 4B).

Next, as shown in FIG. 5A, after connecting the terminal 4a of the electric wire 4 to which the heat-shrinkable tube 5 is attached to the connector terminal 3, the terminal 4a is soldered as shown in FIG. 5B. Connector terminal 3
Fixed to.

Next, as shown in FIG. 5C, a heat-shrinkable tube 5 is placed over the terminal 4a and heat-shrinked to prevent the terminals 4a from contacting each other by soldering.
As shown in FIG. 5D, the end of the electric wire 4 and the connector body 2
Hot melt treatment is applied to the outer peripheral portion (range indicated by a).

As a result, a large number of electric wires 4 can be attached to the connector 1, and a large number of electric signals can be exchanged between the engine or the electronic device and the evaluation device using this wire harness.

[0010]

However, in such a conventional connector 1, after the wires 1 are connected one by one to the connector terminals 3, a soldering operation and heat shrinkage for preventing conduction of the terminals 4a are performed. Since the coating and heating operations of the tube were required, a large amount of time and man-hours were required for the operation of attaching the electric wires 4, and there was a problem that the workability of attaching the electric wires to the connector was extremely low.

Accordingly, the present invention provides a connector and a terminal connected to the connector, which enable the electric wire to be attached easily and in a short time, thereby improving the workability of the electric wire attaching operation. It is intended to be.

[0012]

According to the first aspect of the present invention,
In order to solve the above-mentioned problem, in a connector including a connector body and a plurality of connector terminals that protrude from the inside of the connector body and are connected to terminals of electric wires, a protrusion is formed at a predetermined position of the connector terminal. It is characterized by doing.

In this case, by engaging the wire terminal having the groove formed in the projection provided on the connector terminal, the wire terminal can be easily fixed to the connector terminal. Therefore, it is not necessary to solder the terminals of the electric wires to the connector terminals. Further, since the soldering work is not required, the work of attaching the heat-shrinkable tube for preventing conduction to the terminal of the electric wire can be omitted.

As a result, since the terminal of the electric wire can be fixed to the connector terminal only by connecting the terminal of the electric wire to the connector terminal, the installation of the electric wire can be performed easily and in a short time. Workability can be improved.

According to a second aspect of the present invention, in order to solve the above problems, in the first aspect of the present invention, there is provided a terminal of an electric wire connected to the connector according to the first aspect, wherein the terminal is engaged with the projection. It is characterized by having a groove portion.

In this case, the terminal of the electric wire can be easily and reliably fixed to the connector terminal by engaging the groove formed in the terminal of the electric wire with the projection provided on the connector terminal.

First, the configuration will be described. 1 and 2, reference numeral 11 denotes a connector. The connector 11 includes a connector body 12 and a number of connector terminals 13 projecting from the inside of the connector body 12 to the outside. The terminal 14a of the electric wire 14 is connected.

An opening is formed in the connector body 12, and a connector terminal 13 located inside the connector body 12 is connected to a terminal of another connector fitted in the opening. Has become.

A bent projection 13a is formed substantially at the center of the connector terminal 13 exposed to the outside in the extending direction, and a groove 15 is formed in the terminal 14a.
When the terminal 14a is connected to the connector main body 13, the groove 15 engages with the projection 13a.

In this embodiment having such a configuration,
When the terminal 14a is connected to the connector terminal 13, the terminal 14a can be easily fixed to the connector terminal 13 by engaging the groove 15 formed on the terminal 14a with the projection 13a provided on the connector terminal 13. Can be. Therefore, terminal 14
Need not be soldered to the connector terminal 13.
Further, since the soldering work can be omitted, the work of attaching a heat-shrinkable tube for preventing conduction to the terminal 14a can be omitted.

As a result, since the terminal 14a can be fixed to the connector terminal 13 only by connecting the terminal 14a to the connector terminal 13, the installation of the electric wire 14 can be performed easily and in a short time. Workability of the mounting operation can be improved.

The multi-pole connector 11 of the present embodiment is used for a device requiring a large number of wires as in the case of evaluation characteristics of a vehicle engine or an electronic device, or a device requiring a large number of wires. Electronic device (CPU (Central Processing
Unit)).
