Description

[Detailed description of the invention] This invention relates to a connector.

Conventionally, connectors that use round pins or square pins as male terminals (male connectors) have been widely adopted because of their stability in contact with female connectors, 1J assembly method, and low material cost. Therefore, when the terminal of the round bottle or square bottle is directly attached to the circuit board of an electronic device, it is very inconvenient.

However, it was extremely difficult to connect round bottle or square bottle terminals to electric wires. That is, as shown in FIG. 1, the conventional wire connection method consists of a separate connector 1 in which a connection pin (male terminal) 2 is embedded in an insulating housing 3, and an insulating housing 5.
．． Two female connectors 4.4' housing female terminals 6.6' as shown in FIG.
The electric wires 7 and 7' were connected to '. However,
This connection method requires the use of two wire connectors 4, 4', resulting in high costs and poor economic efficiency.

On the other hand, as another connection method, the male connector 8 similar to the above
One end of the connecting pin 9 (the conductor part 11 of the electric wire 10 is connected by soldering 12. has the advantage that only one piece is needed, but the electric wire 10 can be connected by soldering 12 to the connecting pin 9.
1. Poor solder stain, sheet @
There was a risk of causing many quality problems such as burnt wires, and it also took a lot of time to solder.

Therefore, the purpose of this QT is to provide a connector that can connect electric wires in a capacity of 4-4, has high product reliability, and is also highly economical.

An embodiment of the present invention will be described with reference to FIGS. 4 to 7. That is, as shown in FIGS. 4 to 7, this connector number has an insulating fitting 15 with a through hole 14 drilled therein, and a through hole 141 with a through hole 141 fixed at the tip thereof. More protruding connection pin 16
and the rear end of this connecting pin 16 (sleeve 1 to be fitted)
The relay contact 19 has a wire connection f@918 at the rear end thereof, and a projection 20 for preventing removal provided on the rear end of the connection pin 6 and the snub 17 of the relay contact 19, respectively. It is provided with an engaging groove 21.

As shown in FIG. 7, the through hole 14 of the insulating housing 15 is provided with a small-diameter connection pin insertion portion 14a and a large-diameter relay contact storage portion 1.4b, and the connection pin 16 is inserted into the IL. The relay contact 19 is press-fitted into the insertion part 14a, and the relay contact 19 is stored in the storage part 14b. This relay contact storage portion 14b is located in the adjacent relay contact 1
It prevents short circuits between the two, protects the contact portion from gas, water vapor, etc., and also has sufficient protection functions against vibrations, shocks, etc.

The 111th connection pin 16 is provided with a protrusion 22 at a portion where it is press-fitted into the insulating housing 15, and is configured to prevent the press-fitted connection pin 16 from easily coming off. Also,
A protrusion 20 is provided at the rear end of the connection pin 16, and this protrusion 20 engages with a retaining groove 21 formed in the sleeve 17 of the relay contact 19 to prevent the relay contact 19 from being pulled out. There is. The relay contact 19 has a sleeve 17 fitted into the connection pin 16 and the electric wire 2 as described in GTJ.
．． 3 Wire connection part 18 that connects the conductor part 23a of the workpiece
The sleeve 17 has a longitudinal groove 1.
7a is provided to allow easy insertion of the connecting pin 16, and a contact portion 24 formed slightly narrower than the diameter of the connecting pin 16 is provided to ensure contact with the connecting pin 16. Moreover, the electric wire connection part 18 in this embodiment
Although the electric wire 23 is crimped and fixed, the electric wire 23 may be connected using solder 1-1 No. J or the like.

With this structure, the connecting pin 16 and the electric wire 23 can be easily connected by simply fitting the sleeve 17 of the relay contact 19 connected to the tip of the electric wire 23 into the connecting pin 16, unlike the conventional method. It is highly economical because it does not require the use of two connectors, and it also eliminates quality issues such as poor solder compatibility and short circuits that occur when connecting wires directly to the connection bin with half B1 as in the past. It can even be eliminated.

It should be noted that the projection 20 and the engagement groove 21 for preventing removal may be provided on either the connecting pin 16 or the relay contact 19, and any other arbitrary engagement means may be adopted instead. [It is Noh.

As described above, the connector of the present invention includes an insulating housing, a connecting bin fixed through the insulating housing, and a sleeve bottomed at the rear end of the connecting bin. 5: Holes provided in the relay contact, the rear end of the contact 1N pin, and the sleeve of the mountain joint contact, respectively. can be easily connected,
It has the effect of obtaining the IW1 Hakurei order and is also highly economical.
