Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a connector, and particularly to a connector that can reduce costs.

[Prior art]

Generally, in this type of connector, as shown in FIGS. 3 and 4, an electric wire 25 consisting of a vinyl coating 26 and a conductive wire 27 is inserted through a connector packing 21 having a plurality of annular protrusions on the outer circumferential surface, and A male connection terminal 2 is attached to the end of the electric wire 25.
8 or a female connection terminal 29 are disposed, and a portion of each of the connection terminals 28 and 29 located at the end of the conductor 27 of the electric wire 25 and a portion located at the end of the connector gasket 21 are respectively By caulking, the electric wire 25, the connector gasket 21, and each connection terminal 28, 29 are formed integrally, and the integrally formed object is formed into an opening 33 provided in the cases 23 and 24 made of resin or the like. The male connection terminal 28 and the female connection terminal 29 are configured to be connected to each other at the same time that the cases 23 and 24 are connected to each other via a packing 22 made of an elastic body such as rubber. There is.

Further, the connector gasket 21 is provided with a tightening margin on its outer periphery, and has a sealing property by being pressed in a direction to narrow the tightening margin on the inner surface of the opening 33. This and the sealing properties of the gasket 22 prevent water and the like from entering the inside of the cases 23 and 24.

Furthermore, a male connection terminal 28 is provided inside the opening 33.
and the female connection terminal 29 are respectively provided, and a stopper is provided at the end of the opening 33 to prevent the connector gasket 21 from coming off from the opening 33. 34 are provided respectively.

[Problem that the invention attempts to solve]

However, in the conventional device as described above, one electric wire 25 is inserted through one connector gasket 21.
The connector gaskets 21 are required according to the number of electric wires, and a large number of connector gaskets 21 are required. Furthermore, after the electric wires 25 are inserted, the connector gaskets 21 are inserted into the openings 33 provided in the cases 23 and 24. As a result, a stopper 34 is required to prevent the connector gasket 21 from coming off from the opening 33, and the number of parts increases significantly.
Since a tightening margin is provided in order to obtain sealing performance, it is difficult to insert into the opening 33, and the installation work requires a lot of effort, which significantly increases the cost of the product. In addition, there is a problem in that the gasket 22 may be forgotten to be attached.

This invention solves the problems of the conventional connectors as described above, and aims to provide a connector that can reduce the number of parts, facilitate assembly work, and lower product costs. do.

[Means for solving problems]

In order to solve the above problems, this invention uses a holder that is cylindrical and has a large diameter at one end,
First and second connector packings are formed by integrally molding an elastic body that closes the other end of the holder and surrounds the one end; a case into which one end portions of first and second connector gaskets can be press-fitted, at least one electric wire is inserted through both the connector gaskets, and a connecting terminal is provided at the tip of each electric wire, When both the connector gaskets are fitted into the case, the ends of the case are sealed with an elastic body forming the connector gasket, and the connection terminals of the electric wires are connected to each other. This is a connector configured to

[Effect]

With the connector of this invention constructed as described above, the end of the case can be connected by simply pushing and fitting the connector gasket into which the electric wire with the connecting terminal attached to the end is inserted. The connection terminals are connected to each other in a sealed state.

〔Example〕

Embodiments of this invention shown in the drawings will be described below.

Fig. 1 shows a longitudinal section of the connector according to this invention, and Fig. 2 shows a side view of the connector shown in Fig. 1.The connector shown in Figs. 1 and 2 is made of resin or the like. Connector gaskets 1, 1 integrally formed by baking an elastic body 7 such as rubber around the outside of the holder 6, the connector gasket 1 on one end, and the connector gasket 1 on the other end.
A case 2 made of resin or the like is provided, which is joined to each other, and is further formed of a vinyl coating 8 and a conductive wire 9.
A male connecting terminal 4 is provided at the tip of one of the electric wires 3, and a female connecting terminal 5 is provided at the tip of the other electric wire 3. The terminals 4 and 5 are connected to the electric wire 3 by caulking the engaging portions with the electric wire 3.
and the case 2 is integrally connected to the case 2.
Locking protrusions 10 and 11 are provided inside, respectively, and the male connection terminal 4 is connected to the locking protrusion 1.
0, the female connection terminals 5 are respectively locked by the locking protrusions 11 and held inside the case 2.

Further, the connector gaskets 1, 1 have a convex portion 1.
2 are provided respectively, and recesses 13, 13 are provided at both ends of the case 2, and the protrusions 12 of the connector packings 1, 1 fit into the recesses 13, 13 of the case 2, respectively. , connector gaskets 1 at both ends of the case 2,
1 are connected to each other, and at the same time, the male connection terminal 4 and the female connection terminal 5 are connected to each other, and the recesses 13 and 1 of the case 2 are
The convex portions 12 of the connector gaskets 1, 1 are fitted into the connector gaskets 1, 1, respectively, and the end of the case 2 is sealed with the elastic body 7 that constitutes the connector gaskets 1, 1 fitted, so that the sealing performance is improved. is sufficiently maintained to prevent water and the like from entering the inside of the case 2.

Therefore, in the connector of this invention shown in FIGS. 1 and 2, after the electric wire 3 is inserted into the hole of each connector gasket 1, 1,
The male connection terminal 4 and the female connection terminal 5 are respectively caulked and attached to the tips of the case 2, and after being attached in this manner, both connector gaskets 1, 1 are fitted to both ends of the case 2, and as described above, The connector gaskets 1, 1 are holders 6 made of resin or the like.
The recesses 1 provided at both ends of the case 2 are integrally molded by baking an elastic body 7 such as rubber into the case 2.
By fitting the convex portions 12 provided on the connector gaskets 1, 1 to the connector gaskets 1, 13, the connector gaskets 1, 1 are respectively joined to both ends of the case 2, and the connector gaskets 1, 1 are formed. The elastic body 7 that contacts the end of the case 2 maintains sufficient sealing performance, so only one case is needed instead of two in the past, and the connector gasket can be removed easily. There is no need for parts to prevent the product from separating from the case or to prevent water from entering the case, reducing the number of parts and preventing forgetting to install parts. In addition, it eliminates the need to assemble the connector seal into the case, which was extremely time-consuming in the past, making the assembling process easier and significantly reducing product costs. It is something.

In the above embodiment, the connector gaskets 1, 1 and the case 2 are shown in FIGS. 1 and 2, but the connector gaskets 1, 1 may be made of resin or the like without being limited thereto. Holder 6
Any shape can be used as long as it is integrally molded by baking an elastic body 7 such as rubber on the case 2, and the elastic bodies 7 of the connector packings 1, 1 are respectively joined to both ends of the case 2. Of course, it is also possible.

[Effect of idea]

By configuring this idea as described above,
In addition to reducing the number of parts, the assembly work is extremely easy and product costs can be significantly lowered. Moreover, by simply pushing the connector gasket into the end of the case, the elastic body of the connector gasket can be inserted into the case. Since the end portion of the case is fitted and sealed, it has the effect of reliably preventing water etc. from entering the inside of the case.
