Abstract

<P>PROBLEM TO BE SOLVED: To provide a connector in which manufacturing cost is reduced without increasing the number of components by using a housing formed by one mold as the housing for male use and the housing for female use. <P>SOLUTION: The connector connects and fixes a male terminal housing 1 on which a male terminal is installed and a female terminal housing 2 on which a female terminal is installed, and the both housings include a recess for insertion engagement which is covered with a cover portion of eaves-shape on the connection end face side and an insertion part 5 which is inserted into this recess. The both housings are formed in identical structure formed by an identical mold, and by placing the recess for insertion engagement on upper side on the connection end face side of one housing, and placing the insertion part on the upper side on the connection end face side of the other housing, the other insertion part is insertion-engaged with the one recess for insertion engagement, and the end faces of the both housings are connected and fixed. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a connector.

  Since the connector needs to be held in a coupled state, a lock part is usually formed on one side of both the male and female connectors, and the lock part has a different shape from the lock part for receiving it on the other side. Is formed. That is, engagement means is provided. In general, the male connector is integrally formed with a hood surface for accommodating the female connector. Therefore, the shape of the housing must be different between the female connector and the male connector. In particular, in the type of connector composed of a plurality of blocks as described above, the shape of the female connector and the male connector is different in each block, and if the female connector side and the male connector side are combined, the blocks of different shapes It is necessary to prepare a plurality of molds, which increases the economic burden and the burden on parts management associated with the production of a plurality of types of molds.

Then, what was described in patent document 1 was developed as what shared the male and female connector housing. This is because both the male and female connector housings that can accommodate both male and female terminal fittings, and the male and female terminal fittings connected to each other with the connector housings facing each other A connecting means (engaging means) for holding both connector housings in a locked state by engaging with the housing is provided. With such a configuration, when the male and female connector housings are opposed to each other and the male and female terminal fittings are connected to each other, if both the connector housings are engaged with the connecting means, both connector housings are locked. Retained. That is, even if the connector housing has the same structure and the male and female are shared, they can be connected to each other by the connecting means interposed therebetween. Therefore, since the male / female connector housing can be made common, it is excellent in terms of economy and management.

  In the prior art, since a separate member for housing the connector is required, it is necessary to start a mold for creating the separate member, and the number of parts increases. Further, since a process of attaching another member to the connector occurs, the manufacturing cost also increases.

  An object of the present invention is to provide a connector that does not require a separate member for housing a connector and prevents an increase in the number of parts and an increase in manufacturing cost.

  In order to achieve the above-mentioned object, the present invention provides a connector in which a male terminal housing to which a male terminal is attached and a female terminal housing to which a female terminal is attached is connected and fixed. It has a fitting recess covered with a cover part and an insertion part that fits into this recess, and both housings are formed in the same structure molded from the same mold, and fit on the connection end face side of one housing The joint recess is on the upper side, and on the connection end surface side of the other housing, the insertion portion is faced up, and the other insertion portion is fitted in one of the mating recesses to connect and fix the end surfaces of both housings. .

  The present invention relates to a connector in which a male terminal housing to which a male terminal is attached and a female terminal housing to which a female terminal is attached is connected and fixed, and both housings are fitted with a cover-like cover portion on the connection end face side. It has a recess and an insertion part that fits into this recess, and both housings are formed in the same structure molded from the same mold, with the fitting recess on the connection end face side of one housing, On the connection end face side of the housing, the insertion part is up and the other insertion part is fitted into one fitting recess to connect and fix the end faces of both housings. It can be created by one-part mold start-up, and an increase in the number of parts and an increase in cost can be suppressed.

  Preferred embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a perspective view before a male terminal housing 1 and a female terminal housing 2 are connected and fixed, and the housings 1 and 2 are connected to form a connector.

  The housings 1 and 2 have the same shape and the same structure formed by the same mold, and one housing 1 is rotated 180 degrees around the axis in the connecting direction with respect to the other housing 2. The connection end faces are facing each other.

  Both housings 1 and 2 are provided with a fitting recess 4 covered with an eaves-like cover portion 3 on the connection end face side and an insertion portion 5 fitted into the recess 4. Formed in the same molded structure, one fitting recess is provided with the fitting recess 4 on the connection end face side of one housing 1 and the insertion portion 5 on the connection end face side of the other housing 2. The other insertion portion 5 is fitted to the place 4 to connect and fix the end surfaces of the housings 1 and 2.

  In FIG. 2, the groove portions 6 (two) formed on the inner surface of the upper portion of the cover portion 3 and the concave stripe portions 7 formed on the inner surfaces on both sides of the cover portion 3 are shown. The groove portion 6 engages with the wedge-shaped protrusions 8 (two) formed on the mating insertion portion 5, and the concave strip portion 7 engages with the ridge portions 9 on both sides formed on the mating insertion portion 5. Slides into engagement. Both housings 1 and 2 are formed with holes 10 for receiving terminals (not shown).

  The engaging means for connecting and fixing the housings 1 and 2 is not limited to the illustrated one, and conventional locking means can also be employed.

  In a large number of holes 10 formed in both housings 1 and 2, male terminal fittings and female terminal fittings are accommodated, respectively. Connected. Moreover, both the housings 1 and 2 are formed, for example, by injection molding a synthetic resin material. Even if the molding means are different or the molding materials are different, the housings 1 and 2 have the same shape and the same structure and are molded from one mold.
