Technical Field

The present invention relates to a connector.

Background

Patent document 1 discloses a direct-insertion connector that is fitted to a connector fitting portion of a printed circuit board. This direct plug connector includes: a terminal which is in contact with an electrode provided on a surface of the connector fitting portion; and a locking member that is locked with locking portions provided on both sides of the electrode of the connector fitting portion.

Disclosure of Invention

Problems to be solved by the invention

The direct plug connector described in patent document 1 does not have a structure for suppressing the rattling between the connector fitting portion and the connector fitting portion in a state where the direct plug connector is fitted to the connector fitting portion. Therefore, if the object to which the direct-insertion connector is attached vibrates, the direct-insertion connector may shake with respect to the printed circuit board. Further, the rattling causes a problem that a slight sliding wear occurs between the electrode of the connector fitting portion and the terminal of the direct insertion connector, and the electrical performance is degraded.

The present invention has been made under the above circumstances, and an object thereof is to provide a connector capable of suppressing a decrease in electrical performance.

Means for solving the problems

In order to achieve the above object, a connector according to claim 1 of the present invention is mounted on a board on which a 1 st engaged portion is formed,

the connector includes:

a housing fitted to the substrate;

a 1 st locking part which is provided on or above a 1 st surface of the housing and is locked to the 1 st locked part;

a 1 st operation unit that is pressed by a user to release the engagement; and

a 1 st protruding portion protruding from the 1 st surface of the case toward the substrate for suppressing wobbling of the case with respect to the substrate,

the 1 st protruding portion is provided closer to the 1 st operating portion than the 1 st locking portion in a 1 st direction in which the housing moves to be fitted to the substrate.

The housing may have a housing main body formed with a terminal receiving chamber for receiving the terminal,

the 1 st projection projects from the case main body.

The housing may have:

a housing main body formed with a terminal receiving chamber for receiving a terminal; and

a fixing member mounted to the housing main body for fixing the terminal received in the terminal receiving chamber to the housing main body,

the 1 st projection projects from the fixing member.

Alternatively, the fixing member may be connected to the case main body by a hinge.

The fixing member may be formed separately from the case main body.

The fixing member may be attached to the case main body from a direction orthogonal to the 1 st direction.

The fixing member may be attached to the case main body from the same direction as the 1 st direction.

The connector may include:

a 2 nd locking part arranged on the 2 nd surface of the shell or the surface;

a 2 nd operation portion for being pressed; and

a 2 nd projecting portion that projects from the 2 nd face of the housing toward the substrate and serves to suppress wobbling of the housing with respect to the substrate,

a 2 nd engaged portion to which the 2 nd engaging portion is engaged is formed on the substrate,

the 2 nd protrusion is provided closer to the 2 nd operating portion than the 2 nd locking portion in the 1 st direction.

The connector may further include a 2 nd lock arm, the 2 nd lock arm having the 2 nd locking portion and the 2 nd operating portion, the 2 nd lock arm extending from the 2 nd surface of the housing and configured to be flexible in accordance with a pressing operation of the 2 nd operating portion.
