DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric connector, and more particularly, to a plurality of contacts each having a contact portion at one end, a lead portion at the other end, and an intermediate fixing portion, and aligning the contacts. And a body fixedly supported in a mutually insulated state. Furthermore, the present invention relates to a method for manufacturing such a connector.

[0002]

2. Description of the Related Art In recent years, in the field of portable electronic devices such as notebook personal computers and mobile phones, various electronic components to be built therein have been reduced in size and height as devices have become smaller and thinner. Has been requested. According to such requirements,
For example, even in a board connector used for electrically connecting a pair of circuit boards arranged substantially in parallel with each other, a contact row for the purpose of reducing the occupied area on the board and increasing the number of connection lines are also used. At the same time as the pitch has been reduced, the height of the connector body has been reduced in order to reduce the distance between the two substrates during connection.

Conventionally, in order to reduce the height of this type of connector, a plurality of contacts are respectively provided in a plurality of holes formed in an electrically insulating connector body in both male and female structures, as in the case of a connector of normal size. A configuration is adopted in which the connector is press-fitted and fixed, and the dimensions of the connector body and the contacts are reduced as much as possible. In addition, a connector body is formed by injection molding of a resin material in a state in which a plurality of contacts are arranged and arranged at predetermined positions in a mold, and an insert molding structure having the contacts densely embedded in the connector body is provided. Back connectors are also well known.

In these low-profile connectors, each contact has, at one end, a contact portion that contacts a corresponding contact of a mating connector, the other end has a lead portion that is connected to a circuit on a circuit board, and a contact portion. A fixing portion for fixing to the connector body is provided adjacent to the portion and the lead portion. And in the connector having the above-described press-fit fixed contact, by pressing the fixing portions of the plurality of contacts into each of the plurality of holes of the connector body,
The contact portions and the lead portions of the contacts are arranged at predetermined positions. Further, in the connector having the above-mentioned buried (insert molding) type contact, the fixed portions of the plurality of contacts are integrally buried in the connector main body at the time of molding the connector main body, so that the contact portions and the lead portions of the contacts are formed. It is arranged at a predetermined position.

By the way, in the above-mentioned type of connector, there is a case where a contact portion of each contact is elastically deformed and comes into contact with a corresponding contact of the mating connector when connected to the mating connector. Such a configuration is widely employed, particularly in female or jack connectors.
In this case, each time the connectors are connected and disconnected, the contact portion of each contact of the female connector swings with respect to the connector body with the fixed portion as a fulcrum, so that an accidental short circuit between the adjacent contacts can be prevented. In order to prevent this, a partition wall which is integrally extended from the connector body is usually provided between adjacent contacts.

[0006]

In a conventional connector having a press-fit fixed contact, as the miniaturization and height reduction are promoted, the mutual engagement area between each contact and the connector body is reduced, and the contact is reduced. There is a risk that the fixing force will be significantly reduced. Also,
The presence of a plurality of holes for fixing the contacts lowers the mechanical strength of the connector body, and cracks tend to easily occur around the holes due to press-fitting of the contacts. Furthermore, the shortening of the contacts makes it easier for the flux applied to the surface of the substrate to transfer from the leads of the contacts to the contacts via the fixing portion when the connector is mounted, which may adversely affect the contact function.

On the other hand, in a conventional connector having a buried (insert molding) type contact, the fixing portion of the contact is tightly surrounded by the connector main body. The contact fixing force and the mechanical strength of the connector main body can be maintained, and the transfer of the flux to the contact points of the contact can be prevented. However, in order to form a partition between the above-mentioned contacts in this type of connector, it is necessary that a mold for insert molding has a shape in which a part thereof is arranged in a wall shape adjacent to each contact. As a result, as the pitch of the contact rows becomes narrower, there is a tendency that it is extremely difficult to accurately produce such a mold and form the partition walls.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a connector which can be reduced in size and height, and has a reduced contact fixing force, a reduced mechanical strength of the connector main body, and a reduced mounting time. An object of the present invention is to provide a connector that can effectively eliminate the problem of flux transfer. Another object of the present invention is to
In a connector having a buried (insert molding) type contact, it is easy to make a mold for insert molding even when a partition for preventing short circuit is provided between the contacts in response to the narrow pitch of the contact row. It is to provide a certain connector. Yet another object of the present invention is to provide a method for manufacturing such a connector.

In each base portion 40 of the primary molded body 42, a plurality of recesses 44 on which the fixing portions 34 of the plurality of contacts 16 can be mounted while being positioned are formed in a plurality of groove portions defined between the partition walls 22. 2
6 are provided adjacent to each other. Further, a molten resin material of a secondary molded body 46 to be described later is rolled under each base portion 40 of the primary molded body 42 along an outer edge of a molding surface serving as a mounting surface 18b of the bottom portion 18 of the main body 14. Recess 4
8 are formed.

On the other hand, through a punching, compressing and bending process from a conductive sheet metal material, a large number of contacts 16 are integrally connected in a comb-tooth shape at the end portions 32b of their lead portions 32 via connecting portions 50. The contact blank 52 having the above configuration is formed. Such a contact blank 52 can be formed by a continuous pressing process using a press machine. One contact blank 52 has a number of contacts 16 corresponding to one row mounted on one base 40 of the primary molded body 42. Therefore, two contact blanks 52 are prepared, and the contact portions 30 of the plurality of contacts 16 of each contact blank 52 are prepared.
Are inserted into the plurality of grooves 26 adjacent to each base 40 of the primary molded body 42, and the fixing portions 3 of the contacts 16 are
4 are respectively inserted into the plurality of recesses 44 of each base 40 and placed on the base 40.

Next, as shown in FIG. 7A, an accommodating space 54 for accommodating the primary molded body 42 and the two contact blanks 52, and the secondary molded body 4 combined with the primary molded body 42
6 having a molding space 56 (upper die 58 and lower die 6).

As a result, the fixing portions 34 of the plurality of contacts 16 are tightly surrounded in an embedded manner between each base portion 40 of the primary molded body 42 and the secondary molded body 46, whereby the plurality of contact
Are formed, and a pair of buried support portions 20 are fixedly supported. Since the buried support portion 20 formed in this manner is required to fixedly hold the fixing portion 34 of each contact as described above during insert molding, the step portion 36 is formed on the first wall surface 20a. become. After molding the secondary molded body 46, the connector 1 supporting the pair of contact blanks 52
0 (connector blank) is removed from the mold, and the connecting portion 50 of each contact blank 52 is cut off. Thereby, the lead portions 32 of the plurality of contacts 16 are separated from each other, and the connector 10 shown in FIG. 1 is completed.

The connector 10 having the above-described structure is used for the main body 1.
The fixing portions 34 of the plurality of contacts 16 are arranged in the horizontal direction, that is, the direction along the bottom portion 18, and the lead portions 32 of the contacts 16 have the embedded support portions 20 substantially orthogonal to the bottom portion 18 of the main body 14. First wall surface 20a and second wall surface 20b
, So that the height can be easily reduced. In addition, since the fixing portions 34 of the plurality of contacts 16 are closely surrounded by the respective buried support portions 20 of the main body 14, even if the connector 10 is reduced in size and height, the contact 1 can be reduced.
6 and the mechanical strength of the main body 14 can be maintained. Further, even if the contacts 16 are shortened, it is ensured that the flux applied to the substrate surface 12a moves from the lead portions 32 of the contacts 16 to the contact portions 30 via the fixing portions 34 when the connector 10 is mounted on the surface. Is prevented.

Further, according to the above-described method of manufacturing the connector 10, the partition wall 22 for preventing short-circuiting of the adjacent contacts 16 is provided on the first molded body 42 which is molded in a separate step prior to insert molding. Therefore, even when the pitch of the contact row is narrowed, it can be formed relatively easily. Such a mold of the first molded body 42 may be any one that can form the plurality of partition walls 22 ignoring the presence of the contact 16 and can be manufactured relatively easily and accurately. Thereafter, the second molded body 46 is formed by an insert molding process, and the buried support portion 20 in which the plurality of contacts 16 are buried is formed, so that the contact portions 30 of the contacts 16 are accurately placed in the grooves 26 between the partition walls 22. And a short circuit is prevented.

[0035]

As is apparent from the above description, according to the present invention, in a connector which can be reduced in size and height, by adopting a structure in which contacts are embedded (insert molding), the height is reduced. Thus, it is possible to effectively eliminate the problems of a decrease in the contact fixing force, a decrease in the mechanical strength of the connector body, and a transition of the flux at the time of mounting. Further, even in the case where a partition for preventing short circuit is provided between the contacts, forming the partition on the primary molded body which is molded prior to the insert molding facilitates the production of a mold for insert molding. It is possible to reliably prevent a short circuit between the contacts corresponding to the narrow pitch of the rows.
