Terminal block

Abstract

The present invention provides a terminal block that allows for easy visual confirmation of the position of the gap for inserting the connection terminals, and that facilitates the insertion process. [Solution] This terminal block allows a plate-shaped connection terminal, which is attached to one end of a wire that is held by the user during connection work, to be connected. It has a housing, an energizing member and an opposing member installed in the housing. The energizing member has a surface that is erected facing the side where the user will perform the connection work on the connection terminal. The opposing member is provided in the housing facing this surface, and a gap is formed between it and the surface, which is open on the side where the user will perform the connection work on the connection terminal, into which the connection terminal is inserted. The connection terminal is inserted into the gap along the insertion direction with one plate surface of the connection terminal facing the surface.

Claims

The aforementioned connection terminal is a terminal block that is inserted into the gap along the insertion direction with one of the plate surfaces of the connection terminal facing the aforementioned surface.

2. The terminal block according to claim 1, wherein the connecting terminal is elastically held in the gap.

3. The terminal block according to claim 1, wherein the opposing members protrude toward the surface and have contacts at their tips that contact the connecting terminals inserted into the gap.

4. The opposing member is provided on the elastic member, The elastic member is A base body provided with the aforementioned opposing member, An elastic arm that curves substantially in a C-shape and extends in the direction in which the opposing members of the base body protrude from each other in the direction in which the conductor led out from the connection terminal extends when the connection terminal is inserted into the gap, and toward the side on which the user connects the connection terminal, and has a contact portion on the opposite side of the contact in the direction along the protruding direction that can hold the current-carrying member sandwiched between the contact, and the contact portion is configured to contact the opposing surface of the current-carrying member that is opposite to the surface of the current-carrying member in the direction along the protruding direction, so as to be able to elastically displace the opposing member provided on the base body in the direction opposite to the protruding direction, A terminal block according to claim 3, having the following features.

5. The opposing member is provided on the elastic member, The elastic member is A base body provided with the aforementioned opposing member, It includes an elastic arm that extends in the direction of projection from the base body in which the opposing member protrudes, and that curves in a substantially C-shape toward the side where the user connects the connection terminal, The elastic arm has a contact portion on the opposite side of the contact in the direction along the protruding direction, which can hold the current-carrying member sandwiched between it and the contact, and the contact portion is configured to contact the opposing surface of the current-carrying member that is opposite to the surface of the current-carrying member in the direction along the protruding direction, thereby allowing the opposing member provided on the base to be elastically displaced in the direction opposite to the protruding direction. The terminal block according to claim 3, wherein, among a pair of opposing members of the base that are spaced apart from each other in the direction along the insertion direction, the contact of the opposing member positioned on the front side in the insertion direction is provided in a state that it protrudes in the protruding direction more than the contact of the opposing member positioned on the back side in the insertion direction.

6. The terminal block according to claim 5, wherein the connecting portion of the opposing member, which is positioned on the rear side in the insertion direction, to the base is provided in a protruding state.

7. The terminal block according to claim 4, wherein the contact portion of the contact part that contacts the opposing surface has a predetermined width in a plane perpendicular to the protruding direction and in a direction perpendicular to the insertion direction.

8. The terminal block according to claim 4, wherein the plurality of contacts are arranged substantially point-symmetric with respect to the contact portion of the contact portion that contacts the opposing surface in a plane perpendicular to the protruding direction.

9. The terminal block according to claim 4 or 5, wherein the base body is provided with a corresponding through-hole to a locking member that passes through a through-hole of the connecting terminal inserted into the gap.

10. The terminal block according to claim 4 or 5, wherein the elastic arm is provided with a corresponding through-hole to the locking member that passes through the through-hole of the connecting terminal inserted into the gap.

11. The terminal block according to claim 9, wherein a through hole or a bottomed recess for receiving a part of the locking member is provided on the surface of the current-carrying member, corresponding to the through hole provided in the connection terminal and the corresponding through hole provided in the base, along the protruding direction.

12. The terminal block according to claim 9, wherein the plurality of contacts are arranged substantially symmetrically with respect to the corresponding through holes in a plane perpendicular to the protruding direction.

13. The terminal block according to claim 1, wherein, when the connecting terminal is inserted into the gap, the direction in which the conductor led out from the connecting terminal extends and the direction along which the user connects the connecting terminal are substantially perpendicular to each other.

14. The terminal block according to claim 1, wherein when the connecting terminal is inserted into the gap, the conductor led out from the connecting terminal is configured to move in a direction that aligns with the user's connection work of the connecting terminal.

15. The terminal block according to claim 1, wherein when the connecting terminal is inserted into the gap, the direction in which the user connects the connecting terminal is substantially parallel to the surface.

16. The terminal block according to claim 1, wherein the current-carrying member includes three plate-shaped members connected such that adjacent sides are perpendicular to each other.
