Abstract

A connector according to the present invention comprises a housing and a plurality of contacts. The housing includes a mating portion having a plate shape. The mating portion projects forward and has an upper surface and a bottom surface. The plurality of contacts is held by the housing. Each of the contacts comprises a contact portion, an end portion and a flat portion. The contact portion extends in a connection direction and is exposed at the upper surface of the mating portion. The end portion is embedded in the mating portion. The flat portion forms a boundary between the contact portion and the end portion and does not projects from the upper surface. The flat portion is able to be viewed from above the upper surface of the mating portion.

Claims

1. A connector comprising a housing and a plurality of contacts, the housing including a mating portion having a plate shape, the mating portion projecting forward and having an upper surface and a bottom surface, the plurality of contacts being held by the housing, each of the contacts comprising a contact portion, an end portion, and a flat portion, the contact portion extending in a front-back direction and being exposed at the upper surface of the mating portion, the end portion being embedded in the mating portion, the flat portion forming a boundary between the contact portion and the end portion and not projecting from the upper surface, and the flat portion being viewable from above the upper surface of the mating portion;

wherein;

the connector further comprises a shell formed integrally with the housing by insert-molding;

at least a part of the shell is (i) held by the mating portion, (ii) exposed at the bottom surface of the mating portion and, (iii) connected with a mating shell of a mating connector when the connector is connected with the mating connector;

a hole is formed in the bottom surface of the mating portion, the hole reaching the contact portion; and

the end portion of the contact is viewable neither from above the upper surface nor below the bottom surface.

2. The connector according to claim 1, wherein the flat portion is flush with the upper surface of the mating portion.

3. The connector according to claim 1, wherein the flat portion is in parallel with the upper surface of the mating portion.

5. The connector according to claim 1, wherein the end portion of the contact extends obliquely forward and downward into the mating portion.

6. The connector according to claim 1, wherein a front end of the mating portion has a half-circular shape in a surface perpendicular to the upper surface and the bottom surface and in parallel with the front-back direction.

7. The connector according to claim 1, wherein:

each of the contacts has a connected portion to be connected with a core wire of an electrical cable;

the housing has a plurality of ribs formed at a back of the connected portions in the front-back direction;

the ribs project upward and arrange the core wires on the respective connected portions; and

each of the ribs is positioned between neighboring ones of the connected portions in a pitch direction perpendicular to the front-back direction and an up-down direction, each of the ribs having an oblique surface, and the oblique surface being formed on a front part of the rib so as to be oblique to a surface in parallel with the upper surface of the mating portion.

8. The connector according to claim 1, wherein the contact is formed integrally with the housing by an insert-molding process.

4. A connector comprising a housing and a plurality of contacts, the housing including a mating portion having a plate shape, the mating portion projecting forward and having an upper surface and a bottom surface, the plurality of contacts being held by the housing, each of the contacts comprising a contact portion, an end portion, and a flat portion, the contact portion extending in a front-back direction and being exposed at the upper surface of the mating portion, the end portion being embedded in the mating portion, the flat portion forming a boundary between the contact portion and the end portion and not projecting from the upper surface, and the flat portion being viewable from above the upper surface of the mating portion;

wherein;

each of the contacts has a connected portion to be connected with a core wire of an electrical cable;

the housing has a plurality of ribs formed at a back of the connected portions in the front-back direction;

the ribs project upward and arrange the core wires on the respective connected portions; and

each of the ribs is positioned between neighboring ones of the connected portions in a pitch direction perpendicular to the front-back direction and an up-down direction, each of the ribs having an oblique surface, and the oblique surface being formed on a front part of the rib so as to be oblique to a surface in parallel with the upper surface of the mating portion.

9. The connector according to claim 4, wherein the contact is formed integrally with the housing by an insert-molding process.

10. The connector according to claim 4, wherein the flat portion is flush with the upper surface of the mating portion.

11. The connector according to claim 4, wherein the flat portion is in parallel with the upper surface of the mating portion.

12. The connector according to claim 4, wherein the end portion of the contact extends obliquely forward and downward into the mating portion.

13. The connector according to claim 4, wherein a front end of the mating portion has a half-circular shape in a surface perpendicular to the upper surface and the bottom surface and in parallel with the front-back direction.
