Description

  The present invention relates to a connector mounted on a connection object such as a board, and more particularly to an angle type connector having a shielding function.

  A conventional angle type connector having a shield function will be described (for example, see Patent Document 1).

  As shown in FIG. 6, the plug connector 20 includes a housing 22 having an opening 21 into which a receptacle connector (not shown) is inserted, and a plurality of pin terminals 23 arranged in a grid with respect to the housing 22. Prepare. The housing 22 is U-shaped when viewed from the side, and includes an upper plate 24, a bottom plate 25, and a back plate 26. The housing 22 has a width W smaller than a height H and a length L. Accordingly, in the illustrated example, the pin terminals 23 are arranged in five rows in the height direction of the housing 22 and three rows in the width direction, for a total of 15 pins. All the pin terminals 23 are formed as square pins.

  The housing 22 is entirely formed of an insulating resin, and all the pin terminals 23 penetrate the back plate 26 of the housing 22 in the plate thickness direction. Thereby, each pin terminal 23 is electrically insulated from each other. On the upper plate 24 and the bottom plate 25 of the housing 22, guide inclined surfaces 24a and 25a for facilitating the insertion of the receptacle connector are formed.

  In the housing 22, a plurality of vertical shield plates 27 constituting a plug-side shield are provided at equal intervals in the width direction of the housing 22. Each vertical shield plate 27 is formed in a rectangular plate shape, and is arranged between pin terminals 23 and 23 adjacent to each other in the width direction of the housing 22. Each vertical shield plate 27 is arranged vertically. Thereby, the pin terminal 23 is a form partitioned by the vertical shield plate 27 for every 5 pins in the column (sandwiched by the vertical shield plate from both sides). Each pin terminal 23 has the same length and is longer than the length dimension of the vertical shield plate 27.

  The chiclets press-fitted into the housing 20 will be described later.

  Next, the chiclet 50 will be described. As shown in FIG. 7, the chiclet 50 includes a plurality of pin terminals 23 which are main components of the plug connector 20, a tail 23 a bent 90 degrees to connect these pin terminals to the board, and a plurality of pin terminals. The unit type includes a connection line (not shown) connecting the tail 23a bent by 23 and 90 degrees, a single vertical shield plate 27, and a mold portion 51. The pin terminal 23, the tail 23a, the connection line, and the vertical shield plate 27 are insert-molded at the same time. Therefore, the plug connector 20 includes a housing 22 and a plurality (three) of chiclets 50.

  The rear plate 26 of the housing 22 is provided with an insertion port 26a for the pin terminal 23 and an insertion port 26b for the vertical shield plate 27, respectively. Therefore, the plug connector 20 is configured by press-fitting each chiclet 200 into the housing 22 as shown in FIG.

JP 2002-334752 (page 5, column 7, line 15 to page 6, column 10, line 23, FIGS. 1 to 10)

  The conventional connector has a vertical shield plate 27 disposed between columns (rows in the front-rear direction) of pin terminals 23 (signal contacts). In this case, since the vertical shield plates 27 are disposed only between the columns, measures against noise exerted from the outside are not sufficient.

The first shield plate and the second shield plate are arranged so as to sandwich each of the arranged contacts, and each of the first shield plate and each of the second shield plates has an engaging portion that is connected and fixed to each other. After the first shield plate and each second shield plate are inserted and held in the base insulator, at least one of the contacts, each first shield plate, and each second shield plate is held by the front insulator. Thus, the connector in which the base insulator and the front insulator are assembled.

  2. The connector according to claim 1, wherein the base insulator and the front insulator are combined by combining the stepped portion formed in the base insulator and the stepped portion formed in the front insulator.

  As is apparent from the description of the specification, the present invention has the following effects.

  1. The plurality of first shield plates are formed in a U-shaped cross section except for one, and are arranged between the contacts in the pitch direction of the plurality of contacts, and the plurality of second shield plates are arranged in a direction orthogonal to the pitch direction. Therefore, the connector excellent in shielding can be provided.

  2. After the plurality of contacts, the plurality of first shield plates, and the plurality of second shield plates are inserted and held in the base insulator, at least one of each contact, each first shield plate, and each second shield plate is held by the front insulator. As a result, the base insulator and the front insulator are assembled. Therefore, assembly and disassembly is simple.
