Insulation structure for splice portion, harness mounting plate, and wiring unit
An insulation structure for a splice portion, a harness mounting plate, and a wiring unit that are capable of reducing labor-hours that are required when insulating a splice portion where a plurality of electrical wires are connected by a splice terminal. A plurality of electrical wires are connected by a splice terminal, wherein an opening portion that allows the splice portion to be inserted thereinto and removed therefrom is formed in a splice housing portion that surrounds and insulates the splice portion, and the insulation structure is provided with a separation restricting portion that restricts the splice portion that is housed in the splice housing portion from becoming separated from the opening portion.
1. An insulation structure for a splice portion where a plurality of electrical wires are connected by a splice terminal, comprising:
a splice housing portion having a pair of side wall portions and an opening portion that allows the splice portion to be inserted thereinto and removed therefrom, the pair of side wall portions are separated by a width of the splice housing portion, the splice housing portion surrounds and insulates the splice portion;
a separation restricting portion that restricts the splice portion that is housed in the splice housing portion from becoming separated from the opening portion; and
an electrical wire housing portion having a pair of side wall portions, the pair of side wall portions are separated by a width of the electrical wire housing portion, the electrical wire housing portion houses the electrical wires, wherein the width of the electrical wire housing portion is narrower than the width of the splice housing portion.
2. The insulation structure for the splice portion according to claim 1 ,
wherein the electrical wire housing portion is provided with a coating pressing portion that presses coatings of the electrical wires.
3. A harness mounting plate that is formed using an insulative material, comprising:
a splice holding portion that includes:
a splice housing portion that includes a pair of side wall portions and an opening portion that allows a splice portion where a plurality of electrical wires are connected by a splice terminal to be inserted thereinto and removed therefrom, the pair of side wall portions are separated by a width of the splice housing portion, and the splice housing portion surrounds and insulates the splice portion;
a separation restricting portion that restricts the splice portion that is housed in the splice housing portion from becoming separated from the opening portion; and
an electrical wire housing portion that includes a pair of side wall portions, the pair of side wall portions are separated by a width of the electrical wire housing portion, and the electrical wire housing portion houses the electrical wires, wherein the width of the electrical wire housing portion is narrower than the width of the splice housing portion; and
a harness mounting portion on which a wire harness that includes the electrical wires is to be mounted, wherein the splice portion is provided as a portion of the harness mounting plate.
4. The harness mounting plate according to claim 3 , to be attached to an automatic transmission.
5. A wiring unit comprising:
a wire harness that includes the electrical wires; and
the harness mounting plate according to claim 3 .
