## Abstract

A card edge connector includes a connector including a target engagement part, a substrate that can be inserted into and removed from the connector, a fixing part fixed to the substrate, and a lock that secures the substrate to the connector. The lock includes a shaft fixed to the fixing part and configured to slide in the direction of insertion and removal of the substrate and rotate around an axis, an urging part that exerts force on the shaft and biasing the shaft toward the direction of the substrate, and an engagement part provided on the shaft, configured to engage the target engagement part.

## Claims

### Claim 1

A card edge connector comprising:
a connector including a target engagement part;
a substrate that can be inserted into and removed from the connector;
a fixing part fixed to the substrate; and
a lock that secures the substrate to the connector, the lock includes
a shaft fixed to the fixing part and configured to slide in the direction of insertion and removal of the substrate and rotate around an axis;
an urging part that exerts force on the shaft and biasing the shaft toward the direction of the substrate; and
an engagement part provided on the shaft, configured to engage the target engagement part.

### Claim 2 (depends on 1)

The card edge connector as claimed in claim 1, wherein the engagement part includes an axial part extending in an axial direction of the shaft, a radial part extending in a radial direction of the shaft, and a tangential part extending in a tangential direction with respect to a circumference of the shaft.

### Claim 3 (depends on 1)

The card edge connector as claimed in claim 1,
wherein the target engagement part includes a recess that is recessed in the removal direction, and
the engagement part further includes a protruding part protruding from a distal end of the engagement part, that engages with the recess.

### Claim 4 (depends on 2)

The card edge connector as claimed in claim 2,
wherein the axial part is offset in a radial direction with respect to the shaft.

### Claim 5 (depends on 1)

The card edge connector as claimed in claim 1,
wherein a plurality of the locks are provided in a different area of the substrate and a plurality of the target engagement parts are provided in a different area of the card edge connector, respectively,
wherein one of the engagement part and the target engagement part is arranged diagonally from another one of the engagement part and the target engagement part when viewed from the insertion/removal direction.

### Claim 6 (depends on 1)

The card edge connector as claimed in claim 1, further comprising:
an operation part provided on the shaft.

### Claim 7 (depends on 6)

The card edge connector as claimed in claim 6, wherein the urging part is secured between the operation part and the fixing part.

### Claim 8

A card type module for being inserted into and removed from a connector, the card type module comprising:
a substrate;
a fixing part fixed to the substrate;
a shaft rotatably fixed to the fixing part, configured to slide in a direction of insertion and removal of the card type module;
an urging part that exerts force on the shaft in a direction of removal of the card type module; and
an engagement part provided on the shaft;
wherein the engagement part is configured to engage to a portion of the connector by a rotation of the shaft.

### Claim 9

A connector to which a substrate is insertable, the connector comprising:
a target engagement part configured to engage an engagement part of the substrate;
wherein the engagement part is configured to slide a direction in which the substrate is inserted, and rotate around an axis of an insertion/removal direction.
