[Detailed Description of the Invention] [Industrial Application Field] 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 products as mentioned above.It reduces the number of parts, makes assembly easier, lowers product costs, and improves internal sealing performance. The purpose is to provide a connector that can be significantly improved.

[Means for solving problems]

In order to solve the above problem, the outer circumferential surface of the end of the second cylindrical case comes into contact with the inner circumferential surface of the end of the first cylindrical case, so that they can be joined to each other in a sealed state. and a connector gasket made of an elastic body is provided in the first and second cases, a portion of which is located in a hole provided in both the cases, and the ends of the two cases are closed. A sealed space can be formed, electric wires are provided to be inserted through both the connector gaskets, and connection terminals are provided at the tip ends thereof, and further, in the first case,
It has a cylindrical shape, holds a connecting terminal provided on the electric wire in a predetermined position, and has an outer peripheral surface that is similar to the second
A separator is disposed to abut and support the inner peripheral surface of the end of the second case, and a locking protrusion is integrally formed inside the second case to hold the connecting terminal provided on the electric wire in a predetermined position. However, the connector is characterized in that the connection terminals of both electric wires are connected to each other when both cases are joined.

[Effect]

With the connector constructed as described above, the number of parts can be reduced, assembly work can be facilitated, and product costs can be reduced.

〔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. A connector packing 1 made of a body and a case 3 made of resin or the like are integrally molded, and a connector packing 2 made of an elastic material such as rubber and a case 4 made of resin or the like are integrally molded. In this case, for the cases 3 and 4, the connector gaskets 1 and 2 are partially 1a,
2a are located in the holes 3a, 4a provided in the cases 3, 4, so there is no risk of the cases 3, 4 and the connector gaskets 1, 2 coming off. Furthermore, electric wires 5 formed of a vinyl coating 6 and a conductive wire 7 and inserted through the connector gaskets 1 and 2 are provided, and a male connecting terminal 8 is provided at the tip of one of the electric wires 5, and a male connecting terminal 8 is provided at the tip of one of the electric wires 5. A female connection terminal 9 is provided at the tip of each of the connectors 5 . Both connecting terminals 8 and 9 are fixed to the electric wire 5 by caulking the contact portions with the electric wire 5. Further, the male connecting terminal 8 at the tip of the electric wire 5 is elastically held at a predetermined position with respect to the case 3 by a cylindrical separator 10 having a locking protrusion 11 provided inside the case 3. The female connecting terminal 9 at the tip of the electric wire 5 is elastically positioned at a predetermined position with respect to the case 4 by a locking protrusion 12 provided inside the case 4. There is.

A connector packing 1 is configured such that the male connecting terminal 8 and the female connecting terminal 9 are connected to each other at the same time that the cases 3 and 4 are joined to each other, and further, the connector packing 1 is integrally molded with the case 3. A seal portion 13 is formed in the housing, and the sealing properties of the seal portion 13 prevent water or the like from entering the inside of the cases 3 and 4 which are joined to each other.

Therefore, in the connector of this invention shown in FIGS. 1 and 2, as described above, the connector packing 1 and the case 3, and the connector packing 2 and the case 4 are each integrally molded, and The connector gasket 1 is also provided with a seal portion 13 that prevents water etc. from entering the interior when the cases 3 and 4 are joined together, so conventionally, the connector gasket was prevented from separating from the case. Previously, there were parts to prevent water from entering the case, but since these are no longer needed, the number of parts can be reduced and it also prevents forgetting to install parts. In addition, it was previously very time-consuming.
Since the work of assembling the connector gasket into the case is also unnecessary, the work of assembling can be facilitated and the product cost can be significantly reduced. Further, the other case 4 is assembled with the outer circumferential surface of one case 3 in contact with the inner circumferential surface of the separator 1 in a sealed state.
Since the case 3 and the case 4 are in contact with the outer circumferential surface of the case 0 to form a seal, the interior of the cases 3 and 4 is reliably sealed. Furthermore, connection between the connection terminals is also ensured. That is,
Even if both connection terminals are displaced during connection, since both connection terminals are elastically supported by the locking protrusions 11 and 12, the displacement is absorbed, and therefore,
This is to ensure a secure connection. Connector packing 1
and 2, case 3 and case 4, the first
2 and 2, the connector packing 1 made of an elastic material such as rubber, the case 3 made of resin or the like, and the connector packing 2 made of an elastic material such as rubber are shown in FIG. Of course, any shape may be used as long as the case 4 and the case 4 made of resin or the like are integrally molded.

[Effect of idea]

By configuring this idea as described above,
The number of parts can be reduced, assembly work can be made very easy, and product costs can be significantly lowered. In addition, since a part of the connector gasket is located in the hole in the case, there is no fear that the case and connector gasket will separate, and both connection terminals can be reliably connected by simply joining both cases. In this case, it is possible to assemble the two cases even if they are joined closely with their axes slightly deviated, and the outer circumferential surface of the second case is in contact with the inner circumferential surface of the first case. Furthermore, since the inner peripheral surface is in contact with the outer peripheral surface of the separator provided in the first case, the inside of the case where both connection terminals are provided is double sealed, thereby preventing water etc. from entering the inside of the case. This has the effect that the risk of intrusion is reliably prevented and both electric wires can be electrically connected for a long period of time.
