Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention
A shield plate that performs electrostatic shielding of the installed contacts
The present invention relates to a connector with a shield plate provided. 2. Description of the Related Art Conventionally, in a connector of a board surface mount type,
Fixing brackets are provided at both ends of the housing.
Soldering or screwing the fixture onto the board
Generally, the entire connector is fixed on the board.
You. In addition, several contacts arranged side by side in the housing
To face (or to surround the contact
2) In the case of providing an electrostatic shield by providing a shield plate,
Part of the shield plate pulled out from both ends of the housing
Serves as a fixture to fix the entire connector on the board
And soldered to the ground pattern on the substrate. [0003] By the way, such a core with a shield plate is used.
Nectar generates static electricity generated between adjacent contacts.
Ground through the shield plate and the ground pattern on the board.
Land), noise caused by static electricity
Has the characteristic that it can effectively prevent
You. In such a configuration, the shield plate is
Also plays the role of a fixture that fixes the whole on the board
Therefore, there is an advantage that the number of parts can be reduced. [0004] However, in this case,
In conventional connectors with shield plates, such as
As the number increases (multiple poles), the width dimension of the housing
As the method increases, the stability on the substrate decreases,
When joining or separating
The fixing part may be deformed by receiving or contact
Is twisted and the lead is separated from the signal pattern on the board.
There is a case that a malfunction such as
Was. Also, when the number of contacts increases, the shield plate
Grounding at two places at both ends is no longer sufficient
Performance (static electricity removal characteristics) cannot be obtained and noise
There is also a risk that the harm will increase. The present invention has been made in view of such a problem.
Even if the number of contacts is large,
Can be performed with sufficient strength,
Seal with extremely good shielding characteristics and little harm from noise
It is an object of the present invention to provide a connector with a metal plate. [0006] To achieve the above object,
Therefore, the connector with the shield plate according to the present invention (for example,
For example, in the female connector 200) of the embodiment, the housing
(E.g., the female connector housing in the embodiment)
220) and a plurality of components arranged side by side inside the housing.
Tact (for example, female connector side contour in the embodiment)
240) and these multiple contacts are arranged
In the direction of

Shield plate (for example, the rear shield in the embodiment)
Plate 212), and the intermediate
A plurality of extensions (e.g.,
Leads 217) are in the ground state on the substrate.
Takes a configuration that is joined to the turn. A connector with a shield plate having such a configuration.
Then, it was formed to extend from the middle part of the shield plate
Multiple extensions are connected to the ground pattern on the board.
Is firmly fixed on the substrate,
"Prying" that occurs when joining and separating
There are many shield plates that are strong against "Aori"
The contact with the ground pattern at
The electrostatic shielding characteristics (removal characteristics of static electricity)
