Description

  The present invention relates to a connector, and more particularly to a connector incorporated as an interface in a portable information terminal (PDA) or the like.

As shown in Patent Document 1, a conventional connector includes an insulator, a plurality of terminals held in alignment with the insulator, and a shell covering the outside of the insulator, and the insulator includes: It has a base portion in the longitudinal direction and a fitting portion formed so as to extend forward from the base portion. The fitting portion has a recess formed in a receiving space, and has a contact formed so that the terminal protrudes into the receiving space, and a tail formed so as to protrude the insulator.
Japanese Patent Publication No. 2004-158288

  However, when the terminal is aligned with the insulator so as to protrude into the receiving space and the length of the connector in the longitudinal direction is predetermined, the pitch between adjacent terminals must be narrow, and the terminal signal is transmitted. Could be disturbed. In addition, since the housing space is composed of the fitting portion of the insulator and the shell covers the outside of the insulator, the fitting portion of the insulator needs to maintain a predetermined thickness, and thus the connector It is disadvantageous for low profile. In view of the above-mentioned drawbacks, it is necessary to develop a new electrical connector.

  An object of the present invention is to provide a connector that is advantageous in reducing the height.

In order to achieve the above object, in the present invention, an insulator provided with an extending portion having opposed upper and lower walls and a tip wall connecting the upper and lower walls;
A plurality of terminals attached to the insulator;
In a connector including shells respectively covering the upper and lower walls of the insulator,
A recess is formed in at least one of the upper and lower walls of the extension, and the tip of the recess penetrates the tip wall of the extension and is accommodated between the bottom wall of the recess and the shell. There is obtained a connector comprising a space, a housing groove communicating with the housing space is formed in the bottom wall of the recess, and the terminal has a contact portion extending to the housing groove.

  Compared with the prior art, the present invention has the following advantages. The connector is formed with recesses in the upper and lower walls of the extension part, and the housing space is formed between the bottom wall of the recess and the shell. It is advantageous for turning the back.

  Based on FIGS. 1-7, the connector of this invention is demonstrated. The connector 100 of the present invention includes an insulator 10, a plurality of terminals 20 held by the insulator 10, and a shell 30 that covers the outside of the insulator 10.

  Referring to FIG. 2, the insulator 10 includes a base portion 110 in the longitudinal direction and an extension portion 120 formed so as to extend forward from the base portion 110. Each of the upper and lower walls is provided with a recess 121 formed so as to pass through the distal end wall. Is formed with a fitting portion 122 that fits into the mating connector so as to connect the both concave portions 121 together. Flat portions 123 connected to the fitting portion 122 are formed at both ends of the recess 121. A plurality of terminal grooves 130 for mounting the terminals 20 are formed in the insulator 10, and the plurality of terminal grooves 130 are respectively formed on the upper and lower walls of the fitting part 122 along the longitudinal direction so as to penetrate the base part 110. They are arranged in parallel.

  4 to 6, the terminal 20 is mounted corresponding to the terminal groove 130 of the insulator 10 and is made of an elongated metal plate, and has a contact portion 220 at one end and extends from the contact portion in the length direction. Thus, the holding unit 210 held by the insulator 10 and a tail part 230 extending from the holding unit 210 in the length direction are formed. Since the contact surface of the contact portion 210 of the terminal 20 is on the surface of the metal plate, the contact effect and elastic deformation capability of the terminal 20 can be increased. Since the terminal grooves 130 are alternately arranged on the upper and lower walls of the fitting portion 122, the elastic deformation space of the contact portion 220 of the terminal 20 increases and the fitting portion 122 of the insulator 10 can be thinned. A contact portion 221 is formed at the front end of the contact portion 220, and a convex portion 126 for contacting the contact portion 221 is formed at the front end of the terminal groove 130. The contact portion 221 contacts the convex portion 126. The contact portion 220 can be prevented from being deformed outward by contact.

  Referring to FIGS. 1, 2, and 7, the shell 30 is made of a metal plate, and is connected to connect the first shell 310, the second shell 320, and the first shell 310 and the second shell 320. The first shell 310 and the second shell 320 cover the upper and lower walls of the extending portion 120, respectively, and the connecting portion 330 covers the flat plate portion 123 of the insulator 10. The first shell 30 is provided with a slit 311 formed to be recessed in the flat plate portion 123 in order to guide the fitting to the mating connector 200. The second shell 320 is formed with an engagement arm 321 having a lock portion 322 at the tip, and the engagement between the connector 100 and the mating connector 200 is engaged by the engagement arm 321.

  Since the upper and lower walls of the extending part 120 of the insulator 10 are respectively formed with recesses 121 and the fitting part 122 is formed between the recesses 121 of the upper and lower walls, the first shell 310 and the second shell 320 are formed. Between the upper and lower walls of the fitting portion 122, an accommodation space 300 for accommodating the fitting portion of the mating connector 200 is formed. Since one side of the accommodation space 300 is the insulator 10 and the other side is the shell 30, the fitting portion 122 of the insulator 10 becomes thin, which is advantageous for reducing the height of the connector 100.

  Although the present invention has been described in detail with reference to the preferred embodiments, the embodiments are merely illustrative and are not limited thereto. Further, the above description is intended to be within the scope of the present invention, such as modification or change of details that can be made based on the present invention.
