Description
The present invention relates to a housing assembly for a waterproof connector, and more particularly, to a housing assembly for a waterproof connector, which can be easily manufactured because of the simple structure of the waterproof connector, To a housing assembly for a waterproof connector.
BACKGROUND OF THE INVENTION [0002] In recent years, automobiles have been made electronic by a large number of electronic components and sensors, and they are electrically connected to a control device, a driving device, and a power source through a cable and a cable connector connected thereto. In this process, electromagnetic waves are irregularly generated due to electrical signals, which may lead to malfunctions in sensors or electronic devices controlled by fine signals, leading to traffic accidents.
In order to prevent a malfunction due to the electromagnetic wave, a shielding performance is realized by electrically connecting a connector provided on a harness side of an automobile with a connector (hereinafter referred to as " corresponding connector " Structure. That is, a structure is employed in which the metal housing of the connector and the corresponding metal housing of the corresponding connector are brought into contact with each other to conduct electricity. More specifically, the connector is constructed by assembling a metal housing between the integrated can housing and the outer housing. At this time, the metal housing is provided with contact pieces for ensuring reliability of contact with the corresponding metal housing. A waterproof sealing material is provided between the metal housing and the outer housing to prevent water from entering the connector.
However, in the shielding structure using the connector as described above, the structure of the connector is complicated, and there is a problem that the ground connection on the cable side of the connector is very complicated.
To solve this problem, an inner housing and an outer housing are separately manufactured. However, in this case, as the three parts of the inner housing, the outer housing, and the metal housing are assembled, a tolerance necessary for coupling between the inner housing, the outer housing and the metal housing is generated, and the housings are severely shaken due to the vibration conditions of the vehicle. Accordingly, the connection terminal, which is electrically connected to the inside of the inner housing, is subjected to the stress of vibration, and the electrical connection becomes unstable. As a result, the connection terminal is worn or the connection terminal is deteriorated. Further, there is a problem that the inner housing is separated from the metal housing due to vibration.
In addition, water must not be introduced into the connector by the sealing material mounted on the outer circumferential surface of the metal housing. However, since the outer housing made of the insulating plastic material is deformed due to heat or vibration, There is a problem in that water is introduced into the inside of the vessel.
SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to prevent a sealing material mounted on a metal housing from being pulled out, to securely connect connection terminals by vibration of a vehicle, And a housing assembly for a waterproof connector.
Another object of the present invention is to provide a housing assembly for a waterproof connector, which is easy to manufacture due to the simple structure of the inner housing, the outer housing, and the metal housing, and can improve the vibration resistance as the housings are tightly coupled There is.
In order to achieve the above object, a housing assembly for a waterproof connector of the present invention includes: a metal housing, a part of which is inserted into a corresponding metal housing and has a contact piece formed thereon so as to be in contact with and electrically connected to an inner surface of the corresponding metal housing; A sealing member mounted on an outer circumferential surface of the metal housing and inserted into the corresponding metal housing together with the metal housing; And an inner housing coupled to the metal housing and coupled to the metal housing to support the sealing member so as to be prevented from moving, wherein the sealing member is adapted to receive the corresponding metal housing when the metal housing is inserted into the corresponding metal housing. And is closely attached to the inner circumferential surface of the metal housing to provide a closed structure.
Wherein the inner housing comprises: an insertion portion formed with a slot to which a connection pin is coupled; And a cover portion formed on an outer surface of the insertion portion and configured to surround an outer side of the metal housing so that the sealing material fitted to the outer circumferential surface of the metal housing does not come off, .
At this time, the fastening portion has an engaging groove corresponding to the engaging projection formed on the outer surface of the metal housing, and the fastening portion is elastically deformable so that when the inserting portion is completely inserted into the metal housing, And is inserted into the coupling groove.
In addition, the fastening portion may include an engaging projection corresponding to the engaging groove to engage with an engaging groove formed on an outer surface of the metal housing, and the fastening portion may be elastically deformable so that when the inserting portion is inserted into the metal housing, And the engaging projection is inserted into the engaging groove.
Preferably, the insertion portion and the metal housing are each provided with an erroneous engagement preventing structure for preventing the insertion portion from being erroneously inserted into the metal housing.
Preferably, the erroneous engagement preventing structure is provided in a shape corresponding to each other, and is provided with a guide projection or a mis-engaging groove, and when the inserting portion is inserted into the metal housing, the guide projection is inserted into the erroneous- Loses.
In the meantime, it is preferable that a contact groove portion is formed on the cover portion so that the contact piece provided on the metal housing is exposed to the outside.
The housing assembly for a waterproof connector according to the present invention provides a stable waterproof function by preventing the sealing agent mounted on the metal housing from being pulled out so that the connecting terminal can be stably connected by vibration of the vehicle. Therefore, it is possible to prevent wear of the connection terminal due to vibration and also to prevent deterioration occurring in the connection terminal. Also, since the inner housing and the outer housing can be manufactured separately, it is easy to manufacture, and the inner housing, the outer housing, and the metal housing can be tightly coupled to improve the vibration resistance. In addition, it can be applied to a connector requiring a shielding structure.
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary terms, and the inventor should appropriately interpret the concepts of the terms appropriately It should be construed in accordance with the meaning and concept consistent with the technical idea of the present invention based on the principle that it can be defined.
