Connection structure
View Patent ↗A connection structure includes a first terminal housing with first connecting terminals, a second terminal housing with second connecting terminals, isolating plates in the first terminal housing, a connecting member to collectively fix the first connecting terminals and the second connecting terminals at the contacts therebetween for electrical connections between the first connecting terminals and the second connecting terminals. The connection structure is adapted to heat generated at the contacts through the connecting member, the first terminal housing and/or the second terminal housing to an outside of the first terminal housing.
1. A connection structure, comprising:
a first terminal housing with a plurality of first connecting terminals aligned and accommodated therein;
a second terminal housing with a plurality of second connecting terminals aligned and accommodated therein;
a plurality of isolating plates aligned and accommodated in the first terminal housing, wherein when the first terminal housing and the second terminal housing are fitted to each other, the plurality of first connecting terminals and the plurality of second connecting terminals face each other to form pairs, respectively, and a stacked state is exhibited such that pairs of the first connecting terminals and the second connecting terminals are alternately interleaved with the plurality of isolating plates; and
a connecting member comprising a heat-conducting material and a main body including a head and a shaft connected to the head, the shaft being adapted to penetrate contacts between the plurality of first connecting terminals and the plurality of second connecting terminals and the plurality of isolating plates, the head being adapted to press an adjacent one of the plurality of isolating plates for collectively fixing the plurality of first connecting terminals and the plurality of second connecting terminals at the contacts for electrical connections between the plurality of first connecting terminals and the plurality of second connecting terminals, respectively, the connecting member further comprising at least a portion comprising a nonconductive material for penetrating the contacts,
wherein the connection structure is adapted to dissipate heat generated at the contacts through the connecting member, the first terminal housing and/or the second terminal housing to an outside of the first terminal housing.
2. The connection structure according to claim 1 , wherein the head of the main body is in thermally close contact with the first terminal housing and/or the second terminal housing so as to dissipate heat generated at the contacts through the head of the main body, the first terminal housing and/or the second terminal housing to the outside of the first terminal housing.
3. The connection structure according to claim 1 , wherein the connecting member further comprises a nonconductive portion formed of a nonconductive material and covering an outer circumference of a part except a tip section of the shaft of the main body,
the head and the shaft of the main body comprise a metal, and
the tip section of the shaft of the main body is in thermally close contact with the first terminal housing and/or the second terminal housing.
4. The connection structure according to claim 3 , wherein the tip section of the shaft of the main body comprises a male screw formed thereon, and
the connecting member is fixed in thermally close contact with the first terminal housing and/or the second terminal housing by screwing the tip section of the shaft into a female screw formed on the first terminal housing and/or the second terminal housing.
5. The connection structure according to claim 1 , wherein the head of the main body comprises a heat-insulating cap for preventing a human body part from touching the heated connecting member.
6. The connection structure according to claim 1 , wherein the first terminal housing and/or the second terminal housing comprise a flange formed integrally on an outer circumference thereof for fixing the first terminal housing and/or the second terminal housing to a housing of an external device so as to allow the first terminal housing and/or the second terminal housing to have a thermally close contact with the housing of the external device, and
the connection structure is adapted to dissipate heat generated at the contacts through the connecting member, the first terminal housing and/or the second terminal housing, and the flange to the external device.
7. The connection structure according to claim 1 , wherein the plurality of isolating plates comprise a nonconductive and heat-conducting material, and
at least one of the plurality of isolating plates is in thermally close contact with the first terminal housing and/or the second terminal housing so as to further dissipate heat generated at the contacts through the plurality of isolating plates, first terminal housing and/or the second terminal housing to the outside of the first terminal housing.
8. A connection structure, comprising:
a first terminal housing with a plurality of first connecting terminals aligned and accommodated therein;
a second terminal housing with a plurality of second connecting terminals aligned and accommodated therein;
a plurality of isolating plates aligned and accommodated in the first terminal housing, wherein when the first terminal housing and the second terminal housing are fitted to each other, the plurality of first connecting terminals and the plurality of second connecting terminals face each other to form pairs, respectively, and a stacked state is exhibited such that pairs of the first connecting terminals and the second connecting terminals are alternately interleaved with the plurality of isolating plates; and
a connecting member comprising a heat-conducting material and a head, the head being adapted to press an adjacent one of the plurality of isolating plates for collectively fixing the plurality of first connecting terminals and the plurality of second connecting terminals at the contacts for electrical connections between the plurality of first connecting terminals and the plurality of second connecting terminals, respectively,
wherein the plurality of isolating plates comprise a nonconductive and heat-conducting material, and
at least one of the plurality of isolating plates is in thermally close contact with the first terminal housing and/or the second terminal housing so as to dissipate heat generated at the contacts through the plurality of isolating plates, first terminal housing and/or the second terminal housing to an outside of the first terminal housing.
9. The connection structure according to claim 1 , wherein the first terminal housing and/or the second terminal housing comprise a metallic material.
10. The connection structure according to claim 8 , wherein the first terminal housing and/or the second terminal housing comprise a metallic material.
11. The connection structure according to claim 1 , wherein the first terminal housing and/or the second terminal housing comprise a heat-conducting resin.
12. The connection structure according to claim 8 , wherein the first terminal housing and/or the second terminal housing comprise a heat-conducting resin.
