Abstract

A terminal base includes a plurality of terminals configured to electrically connect a first device and a second device to each other, each of the plurality of terminals being electrically conductive and a housing configured to hold the plurality of terminals, the housing being made of an electrically insulating resin in which each of the plurality of terminals includes a first connection portion exposed to an outside of the housing so as to be connected to the first device, a second connection portion exposed to the outside of the housing so as to be connected to the second device, and an insert portion insert-molded in the housing and in which he insert portion has a solid cylindrical shape or a hollow cylindrical shape.

First claim

What is claimed is:

1. A terminal base comprising:
a plurality of terminals configured to electrically connect a first device and a second device to each other, each of the plurality of terminals being electrically conductive; and
a housing configured to hold the plurality of terminals, the housing being made of an electrically insulating resin,
wherein each of the plurality of terminals comprises a first connection portion exposed to an outside of the housing so as to be connected to the first device, a second connection portion exposed to the outside of the housing so as to be connected to the second device, and an insert portion insert-molded in the housing,
wherein the insert portion has a solid cylindrical shape or a hollow cylindrical shape,
wherein the insert portion comprises a surface processed portion over an entire circumference of an outer surface of the insert portion, and
wherein the surface processed portion is formed by laser processing and is formed in a shape having minute irregularities.

2. The terminal base according to claim 1 ,
wherein, for each of the plurality of terminals, the first connection portion extends in a direction substantially orthogonal to a direction in which the insert portion extends, and
wherein the housing is configured such that, positions at which the insert portions of the plurality of terminals are located in the housing are arranged along a curve.

3. The terminal base according to claim 1 ,
wherein the insert portion has the hollow cylindrical shape including an opening and a bottom wall, and
wherein the bottom wall is the second connection portion.

4. The terminal base according to claim 1 ,
wherein each of the plurality of terminals has a first bent portion located between the first connection portion and the insert portion,
each of the plurality of terminals has a second bent portion located between the insert portion and the second connection portion,
for each of the plurality of terminals, a tip end of the first connection portion extends in a direction orthogonal to a direction in which the insert portion extends, and
the second connection portion extends in a direction that is orthogonal to the insertion portion, and the second connection portion and the first connection portion extend in opposing directions.

5. The terminal base according to claim 1 ,
wherein the first connection portion, the second connection portion and the insert portion are formed integrally with each other as a one-piece structure.

6. An electrical connection structure of devices comprising:
a first device;
a second device; and
a terminal base,
wherein the first device and the second device are electrically connected with each other by the terminal base, and
wherein the terminal base comprises;
a first plurality of terminals configured to electrically connect the first device and the second device to each other, each of the first plurality of terminals being electrically conductive; and
a housing configured to hold the first plurality of terminals, the housing being made of an electrically insulating resin,
wherein each of the first plurality of terminals comprises a first connection portion exposed to an outside of the housing so as to be connected to the first device, a second connection portion exposed to the outside of the housing so as to be connected to the second device, and an insert portion insert-molded in the housing,
wherein the insert portion has a solid cylindrical shape or a hollow cylindrical shape,
wherein the insert portion comprises a surface processed portion over an entire circumference of an outer surface of the insert portion, and
wherein the surface processed portion is formed by laser processing and is formed in a shape having minute irregularities.

7. The electrical connection structure according to claim 6 ,
wherein, for each of the first plurality of terminals, a tip end the first connection portion extends in a direction orthogonal to a direction in which the insert portion extends.

8. The electrical connection structure according to claim 6 ,
wherein the first device has a second plurality of terminals and the second device has a third plurality of terminals,
the first connection portions of the first plurality of terminals of the terminal base are mounted to the second plurality of terminals of the first device, and
the second connection portions of the first plurality of terminals of the terminal base are mounted to the third plurality of terminals of the second device.

9. The electrical connection structure according to claim 6 ,
wherein the first connection portion, the second connection portion and the insert portion are formed integrally with each other as a one-piece structure.
