Protective case for electric wires
View Patent ↗A protective case includes a case body allowing a corrugated tube with an inserted electric wire to be housed in its inside, and a slider configured to move together with one end portion of the corrugated tube and to allow its movement along the case body. The slider retains the electric wire withdrawn from the one end portion to extend from inside to outside through one opening portion of the case body. The case body has a cavity portion allowing the corrugated tube to change its form inside the case body in accordance with the movement of the slider, a guide passage guiding the electric wire withdrawn from the other end portion of the corrugated tube toward another opening portion of the case body, and a corrugated tube retention portion including a pair of wall surfaces to retain the other end portion of the corrugated tube.
1. A protective case for electric wires, the protective case comprising:
a case body allowing a corrugated tube with an inserted electric wire to be housed in its inside; and
a slider configured to move together with one end portion of the corrugated tube and to allow its movement along the case body, the slider retaining the electric wire withdrawn from the one end portion to extend from inside to outside through one opening portion of the case body,
the case body having:
a cavity portion allowing the corrugated tube to change a form of the corrugated tube inside the case body in accordance with the movement of the slider;
a guide passage guiding the electric wire withdrawn from the other end portion of the corrugated tube toward another opening portion of the case body to allow the electric wire to be extended to outside the case body through the another opening portion, the other end portion of the corrugated tube being located inside the case body; and
a corrugated tube retention portion including a pair of wall surfaces, the corrugated tube retention portion is configured to retain the other end portion of the corrugated tube between the cavity portion and the guide passage.
2. The protective case according to claim 1 , wherein
the case body has an opening area of the guide passage, at a place where the guide passage and the corrugated tube retention portion are connected, to eliminate the other end portion of the corrugated tube to pass through the place.
3. A protective case for electric wires, the protective case comprising:
a case body allowing a corrugated tube with an inserted electric wire to be housed in its inside; and
a slider configured to move together with one end portion of the corrugated tube and to allow its movement along the case body, the slider retaining the electric wire withdrawn from the one end portion to extend from inside to outside through one opening portion of the case body,
the case body having:
a cavity portion allowing the corrugated tube to change a form of the corrugated tube inside the case body in accordance with the movement of the slider;
a guide passage guiding the electric wire withdrawn from the other end portion of the corrugated tube toward another opening portion of the case body; and
a corrugated tube retention portion including a pair of wall surfaces to retain the other end portion of the corrugated tube between the cavity portion and the guide passage, wherein
the case body has an opening area of the guide passage, at a place where the guide passage and the corrugated tube retention portion are connected, to eliminate the other end portion of the corrugated tube to pass through the place, and
the case body is configured to locate an opening position of the guide passage, at the place where the guide passage and the corrugated tube retention portion are connected, to offset from an opening position of the other end portion of the corrugated tube retained by the corrugated tube retention portion.
