Abstract

A housing of a linear conductor connection terminal is provided with a first contact point portion having a recessed portion composed of a metal plate and opening inwardly of the housing. The recessed portion allows insertion of a linear conductor inserted into the housing from an insertion port. The housing is further provided with a second contact point portion that supports contact between the linear conductor and the first contact point portion. This allows the linear conductor to reliably conductively contact the first contact point portion and the second contact point portion.

First claim

What is claimed is:

1. A linear conductor connection terminal comprising a housing having an insertion port for a linear conductor and fixed to a substrate,
wherein the housing has
a top surface and a bottom surface extending in parallel with a substrate,
a first contact point portion having a recessed portion composed of a metal plate and opening inwardly of the housing, the first contact point portion allowing insertion, and
a second contact point portion that contacts the linear conductor inserted from the insertion port configured to support contact between the linear conductor and the first contact point portion,

wherein the recessed portion has
a first wall continuously and inwardly extending from the top surface of the housing toward an inside of the housing, and
a second wall extending perpendicularly and inwardly of the housing from both side ends of the first wall,
the first wall and each second wall configured to guide the linear conductor inserted from the insertion port to a back side inside the housing so as to secure the contact between the linear conductor and the first contact point portion.

2. The linear conductor connection terminal according to claim 1 ,
wherein the first contact point portion is formed by bending a part of the metal plate forming the housing into a recessed shape.

3. The linear conductor connection terminal according to claim 1 , wherein the first contact point portion and the second contact point portion are formed as a part of the metal plate forming the top surface of the housing and a part of the metal plate forming the bottom surface of the housing.

4. The linear conductor connection terminal according to claim 1 ,
wherein the first contact point portion has a coupling portion that has spring elasticity and that connects between the recessed portion and the housing in a cantilever manner along the insertion direction, and the coupling portion is formed as a part of the metal plate that is integral with the housing and the recessed portion.

5. The linear conductor connection terminal according to claim 1 ,
wherein the first contact point portion is formed on one surface of the housing, and formed to be inclined toward an inside of the housing from one end side, from which the linear conductor is inserted, to the other end.

6. The linear conductor connection terminal according to claim 1 ,
wherein the first contact point portion and the second contact point portion are provided opposite to each other across a center axis of the linear conductor inserted into the housing, and formed to be inclined closer to the center axis from a side from which the linear conductor is inserted.

7. The linear conductor connection terminal according to claim 1 ,
wherein the first contact point portion and the second contact point portion are each formed as an elastic piece that abuts with the linear conductor inserted into the housing to be elastically displaced.

8. The linear conductor connection terminal according to claim 1 ,
wherein the linear conductor has an electrically insulating sheath, and
the insertion port is formed with such a size that allows insertion of the linear conductor but that does not allow insertion of the sheath.

9. The linear conductor connection terminal according to claim 1 ,
the top surface is at the same height as or proximate in height to an upper end of the sheath of the linear conductor, and
the bottom surface is at the same height as or proximate in height to a lower end of the sheath.

10. A linear conductor connection terminal according to claim 1 , the first wall, each second wall, and the second contact point portion guides the linear conductor inside the housing from the insertion port towards a back side of the housing by four directions configured to secure the contact between the linear conductor and the first and second contact point portions.

11. A linear conductor connection terminal according to claim 1 , the first wall further having a contact point edge located at a terminal end edge closest inwardly configured to contact the linear conductor.

12. The linear conductor connection terminal according to claim 1 , wherein the first contact point portion has a contact point edge formed by a corner portion of the metal plate that contacts the linear conductor,
the second contact point portion has a contact point edge formed by a corner portion of a metal plate that contacts the linear conductor, and
the contact point edge of the first contact point portion and the contact point edge of the second contact point portion are engaged with the linear conductor to contact the linear conductor.

13. The linear conductor connection terminal according to claim 12 , wherein the contact point edge of the first contact point portion and the contact point edge of the second contact point portion are disposed opposite to each other to hold the linear conductor therebetween.

14. The linear conductor connection terminal according to claim 1 ,
wherein the housing includes a lever that displaces at least one of the first contact point portion and the second contact point portion in a direction away from the linear conductor.

15. The linear conductor connection terminal according to claim 14 ,
wherein the lever is formed by bending a part of the metal plate forming the housing.

16. The linear conductor connection terminal according to claim 14 ,
wherein the lever has an operation portion with a width that is larger than an outside diameter of the linear conductor inserted into the housing.

17. The linear conductor connection terminal according to claim 14 ,
wherein at least one of the first contact point portion and the second contact point portion is formed as an elastic piece by cutting and raising a part of the metal plate forming the lever.

18. The linear conductor connection terminal according to claim 14 ,
wherein the linear conductor has an electrically insulating sheath, and
the insertion port is formed with such a size that allows insertion of the linear conductor but that does not allow insertion of the sheath.

19. The linear conductor connection terminal according to claim 14 ,
the top surface is at the same height as or proximate in height to an upper end of the sheath of the linear conductor, and
the bottom surface is at the same height as or proximate in height to a lower end of the sheath.
