Description

connector

The present disclosure relates to a connector including a plurality of terminals arranged in parallel with each other.

A connector having a plurality of terminals disposed on a housing is used for, for example, electrically connecting a circuit board on which an electronic circuit is provided, a control device, and various electronic control components (control target devices). For example, as disclosed in Patent Document 1, when a connector is mounted on a transmission (transmission) or the like that uses oil, a device for preventing oil from leaking from the connector to the outside of the transmission or the like is devised. Has been done. Specifically, when manufacturing a connector, a plurality of terminals are arranged in a molding die, insert molding of a resin housing is performed, and then a resin potting material is cast into a recess formed in the housing. Is going. And, by adhering the potting material to the plurality of terminals, oil is prevented from leaking to the outside of the connector along the terminals.

JP-A-2015-125973

非 In a non-waterproof type connector in which a sealing material is not attached to a plurality of terminals, a potting material is generally used to prevent leakage of oil, water, and the like. However, since the potting material is formed by casting, it cannot be formed in a required shape. Then, the surface after casting the potting material becomes flat. Therefore, for example, an insulating rib (insulating wall) for insulating between terminals cannot be formed on the surface of the potting material.

In addition, in the non-waterproof type connector, in order to secure molding flexibility, the housing may be constituted by a first housing portion and a second housing portion which are separately molded from each other. Specifically, a part of the housing is separately formed as a first housing portion as a core, each terminal is pressed into the first housing portion, and the first housing portion and each terminal are arranged in a molding die. Then, it is conceivable to perform insert molding for injecting a resin into the molding die to form the second housing portion.

However, it was discovered during the research and development of the inventor that there was still another problem when performing insert molding of the second housing portion using the first housing portion. That is, when insert molding the second housing portion, the resin for molding the second housing portion protrudes from the back side of the first housing portion through the gap between the first housing portion and each terminal, and burrs ( (Projections).

As a result, if a potting material for sealing the boundary between each terminal and the housing is to be provided in the formed housing composed of the first housing portion and the second housing portion, the following problem occurs. . That is, when the burr of the second housing portion is formed so as to protrude into the space for injecting the potting material, the burr inhibits adhesion between each terminal and the potting material and ensures sufficient sealing of the connector. I found that I could not do it. Therefore, further measures are required to ensure sufficient sealing of the connector and increase the degree of freedom for forming the housing into a required shape.

The present disclosure has been made in view of such a problem, and has been made in an effort to provide a connector that can ensure the hermeticity at the time of manufacture and use and can increase the degree of freedom for forming a housing into a required shape. It was done.

One embodiment of the present disclosure includes a plurality of terminals arranged in parallel with each other,
An inner housing made of a thermoplastic resin, through which the plurality of terminals are inserted,
A gasket provided on the inner housing and closely attached to the plurality of terminals,
A main body portion in which the inner housing and the gasket are embedded, and a pair of mounting portions protruding from the main body portion and respectively surrounding both ends of the plurality of terminals, and an outer housing made of a thermoplastic resin. is there.

The connector according to the one aspect, when forming a non-waterproof type connector in which a sealing material is not attached to a plurality of terminals, forms a housing from two parts of an inner housing and an outer housing, and includes a gasket provided in the inner housing. The surface is covered by the outer housing. Specifically, when the plurality of terminals are inserted through the inner housing, the inner housing is provided with a gasket which is in close contact with the plurality of terminals. In addition, the connector functions as a relay connector in which each female connector is mounted on each mounting portion of the housing and an end of each terminal surrounded by each mounting portion, and the electrical connection of each female connector is relayed by a plurality of terminals. I do. When the connector is used, the provision of the gasket prevents liquid such as oil and water from leaking to the outside of the connector through the plurality of terminals.

The inner housing and the gasket are embedded in the main body of the outer housing. The surface of the gasket is covered by the main body of the outer housing. Therefore, the shape required for the connector does not need to be formed on the surface of the gasket, and can be formed on the main body of the outer housing. Thus, for example, an insulating wall that insulates between the terminals can be formed on the main body of the outer housing located in the mounting portion.

Also, when molding the outer housing, a gasket may be provided on the inner housing integrated with the plurality of terminals to form an insert part, and this insert part may be arranged in a molding die to insert-mold the outer housing. it can. At this time, the gasket is in close contact with the plurality of terminals, and there is almost no gap between the plurality of terminals and the gasket. Therefore, the thermoplastic resin serving as the outer housing cannot penetrate into the gap between the plurality of terminals and the gasket. Thereby, the connector can be manufactured while ensuring the sealing property between the plurality of terminals and the gasket.

Therefore, according to the connector of the above aspect, the sealing property of the connector is ensured during manufacture and use of the connector, and the degree of freedom for forming the housing into a required shape can be increased.

The valve body in an oily environment is filled with transmission oil (hydraulic oil), and the second mounting portion 52 and the second end 22 of the terminal 2 in the connector 1 are in a state where the oil easily contacts the oil. It is in. The oil adhering to the second end 22 of the terminal 2 arranged in the oil environment tends to permeate to the first end 21 of the terminal 2. At this time, since the gasket 6 is in close contact with the terminal 2, the gasket 6 prevents oil from penetrating into the first end 21 of the terminal 2.

コネクタ As shown in FIGS. 1 to 3, the connector 1 is held in the oil-side holding hole 722 provided in the case 721 of the transmission.

Intermediate portions 23 of the plurality of terminals 2 except for the first end 21 and the second end 22 are embedded in the inner housing 4, the gasket 6, and the outer housing 5.

テーパ As shown in FIG. 1, a tapered portion 231 for press-fitting into the inner housing 4 is formed in the intermediate portion 23 of the plurality of terminals 2. The tapered portion 231 serves as a guide portion when each terminal 2 is pressed into the press-fit hole 43 of the inner housing 4. Further, in the intermediate portion 23 of the plurality of terminals 2, there is formed a separation mark 232 of the carrier (connection portion) when the plurality of terminals 2 are formed in a state of being connected to each other. The division mark 232 serves as a stopper for preventing each terminal 2 from coming out of the inner housing 4 after each terminal 2 is pressed into the inner housing 4.

The division mark 232 is a portion of the terminal 2 where the cross-sectional shape orthogonal to the direction in which the terminal 2 is formed is the largest. The plurality of terminals 2 are each press-fitted into a plurality of press-fit holes 43 provided in the inner housing 4. The configuration in which the plurality of terminals 2 are press-fitted facilitates the molding of the inner housing 4. Instead of press-fitting the plurality of terminals 2, the plurality of terminals 2 are arranged in a molding die, and insert molding of the inner housing 4 is performed in this molding die, so that the inner housing 4 in which the plurality of terminals 2 are inserted is removed. Molding is also possible.

The inner housing 4 can also be formed.

Next, as a casting step, as shown in FIG. 7, a liquid gasket is injected (potted) into the first recess 41 of the inner housing 4 to fill it. At this time, the liquid gasket contacts a part of each terminal 2 arranged in the first recess 41. Then, when heat is applied to the gasket in the liquid state, the gasket in the liquid state hardens, and the gasket 6 is formed in the first recess 41. Thus, the gasket 6 can be easily formed in the first recess 41 of the inner housing 4.

Thus, the gasket 6 is disposed inside the outer housing 5. Specifically, when the plurality of terminals 2 are inserted into the inner housing 4, the inner housing 4 is provided with a gasket 6 which is in close contact with the plurality of terminals 2. In the connector 1, the

female connectors

81 and 82 are mounted on the mounting

portions

insertion portions

501 and 502 of the main body 50 of the outer housing 5. Therefore, the shape required for the connector 1 does not need to be formed on the surface of the gasket 6, and can be formed on the

insertion portions

501 and 502 of the main body 50 of the outer housing 5. In particular, in the present embodiment, an insulating rib 503 for insulating between the terminals 2 can be formed in the second insertion portion 502 of the main body 50.

Thus, the outer housing 5 can be insert-molded. At this time, the gasket 6 is in close contact with the plurality of terminals 2, and there is almost no gap between the plurality of terminals 2 and the gasket 6. Therefore, the thermoplastic resin serving as the outer housing 5 cannot penetrate into the gap between the plurality of terminals 2 and the gasket 6. As a result, burrs of the thermoplastic resin (resin penetrating into the gaps) are not formed around the plurality of terminals 2, and the sealing property between the plurality of terminals 2 and the gasket 6 is ensured to manufacture the connector 1. Can be.

Therefore, according to the connector 1 of the present embodiment, the sealing property of the connector 1 is ensured during the manufacture and use of the connector 1, and the degree of freedom for forming the housing 3 into a required shape can be increased.

以外 The first recess 41 may be formed separately for each of the terminals 2 or for each of several terminals 2, in addition to being formed collectively for the plurality of terminals 2. Also in this case, the gasket 6 arranged in the first concave portion 41 has an effect of preventing permeation of a liquid such as oil from the second end 22 of each terminal 2 to the first end 21. This case is particularly effective when the number of terminals 2 is small.
