Insulating structure between conductive members of electric device
View Patent ↗An insulating structure is employed between conductive members of an electric device. The electric device has a housing accommodating electric components therein and a cover member covering the housing, the conductive members being disposed through communication holes of the housing and the cover member. The insulating structure includes contact prevention members for preventing water infiltrated into a gap between the housing and the cover member from contacting water collected in the communication holes for the conductive members, wherein the contact prevention members are interposed between the housing and the cover member. Each contact prevention member has a substantially annular shape, surrounding one of the conductive members.
1. An insulating structure between conductive members of an electric device, the electric device including a housing accommodating electric components therein and a cover member covering the housing, the conductive members being disposed through communication holes of the housing and the cover member, the insulating structure comprising:
contact prevention members for preventing water infiltrated into a gap between the housing and the cover member from contacting water collected in the communication holes for the conductive members, wherein the contact prevention members are interposed between the housing and the cover member, and each contact prevention member has a substantially annular shape, surrounding one of the conductive members.
2. The insulating structure of claim 1 , wherein each contact prevention member includes a first contact prevention part in firm contact with the housing and a second contact prevention member in firm contact with the cover member, and each contact prevention member is formed as one body with a sealing member sealing a gap between the housing and the conductive member.
3. The insulating structure of claim 1 , wherein each contact prevention member includes a first contact prevention part in firm contact with the housing and a second contact prevention part in firm contact with the cover member, and the contact prevention member is formed as one body with the cover member, separately from a sealing member sealing a gap between the housing and the conductive member.
4. The insulating structure of claim 1 , wherein each contact prevention member is a protrusion whose leading end is in firm contact with a sealing member sealing a gap between the housing and the conductive member, the protrusion being formed as one body with the cover member.
5. The insulating structure of claim 1 , wherein each contact prevention member is a protrusion whose leading end is in firm contact with the cover member, the protrusion being formed as one body with the housing, and an elastic member is provided at a portion of the cover member in firm contact with each contact prevention member.
6. The insulating structure of claim 1 , wherein each contact prevention member is an O-ring which is in firm contact with the housing and the cover member.
7. The insulating structure of claim 2 , wherein each contact prevention member formed as one body with the sealing member is formed with the housing by dual injection molding.
8. The insulating structure of claim 3 , wherein each contact prevention member formed as one body with the cover member is formed with the cover member by dual injection molding.
9. The insulating structure of claim 1 , wherein water drain grooves for draining the water infiltrated into the gap between the housing and the cover member are provided at an inner surface of the cover member.
10. The insulating structure of claim 1 , wherein the electric device is an electric shaver, and the electric shaver is charged via the conductive members when the electric shaver is mounted in a charging device.
11. The insulating structure of claim 1 , wherein the cover member serves as a decorative panel.
12. The insulating structure of claim 1 , wherein the conductive members include tips being protruded from a surface of the cover member.
13. The insulating structure of claim 1 , further comprising a sealing member sealing a gap between the housing and the conductive member, wherein the sealing member is inserted into an attachment groove provided at the housing.
