Shield connector and connector connection structure
A shield connector can easily suppress contact failure between terminal metal fittings due to vibration, and a connector connection structure can include the shield connector. In a large-diameter part in the natural state, a direction dimension passing through a tip of a protrusion is larger than a fastening direction dimension from an abutting part to a first clamping part in the shield case, a fastening member inserted into a fixed part is fastened, and the inner housing is thus hard to vibrate in the shield case. Therefore it is possible to suppress poor contact between a terminal fitting held by the inner housing and a mating terminal fitting. At this time, it is unnecessary to add a new process in order to suppress vibration of the inner housing, easily suppressing a contact failure between the terminal fittings.
1. A shield connector to be connected to a device-side connector attached to a casing of an in-vehicle device, the shield connector comprising:
an inner housing configured to hold a terminal fitting; and
a shield case including a housing part housing the inner housing and a fixed part configured to be placed on an outer surface of the casing, through which a fastening member is inserted so as to be fixed to the casing, wherein
the housing part includes an abutting part configured to abut against the outer surface, and a clamping part configured to be separated from the outer surface in a fastening direction and to sandwich the inner housing between the clamping part and the outer surface, wherein the inner housing includes, at a clamped part to be sandwiched between the outer surface and the clamping part, a protrusion protruding toward the outer surface or the clamping part, wherein a fastening direction dimension passing a distal end of the protrusion at the clamped part in a state before fastening the fastening member is larger than a dimension from the abutting part to the clamping part in the shield case, and wherein
the protrusion is monolithical with the inner housing.
2. The shield connector according to claim 1 , wherein
the fastening direction dimension passing a base end of the protrusion at the clamped part in the state before fastening the fastening member is smaller than the dimension from the abutting part to the clamping part in the shield case.
3. The shield connector according to claim 1 , wherein
a terminal connecting direction in which the terminal fitting and a terminal fitting of the device-side connector are connected is oriented in the fastening direction.
4. The shield connector according to claim 2 , wherein
a terminal connecting direction in which the terminal fitting and a terminal fitting of the device-side connector are connected is oriented in the fastening direction.
5. A connector connection structure, wherein
the shield connector according to claim 1 and the device-side connector are connected.
6. A connector connection structure, wherein
the shield connector according to claim 2 and the device-side connector are connected.
7. A connector connection structure, wherein
the shield connector according to claim 3 and the device-side connector are connected.
8. A connector connection structure, wherein
the shield connector according to claim 4 and the device-side connector are connected.
9. The shield connector according to claim 1 , wherein the clamped part of the inner housing has a cylindrical part.
10. The shield connector according to claim 9 , wherein the clamped part of the inner housing is continuously connected in between the outer surface of the casing and the clamping part of the housing part.
11. The shield connector according to claim 1 , wherein the protrusion and the clamped part are unitary.
12. The shield connector according to claim 1 , wherein a cross-sectional area of the protrusion is a taper shape.
