Abstract

A connector includes: a terminal, and a housing holding the terminal, the connector being mounted on a substrate with a liquid potting agent applied thereto, wherein: the housing includes a mating recess mating with a counterpart connector, along with a bottom plate part in which a terminal press-in hole with the terminal pressed therein is formed, the terminal includes a contact part contacting a counterpart terminal of the counterpart connector in the mating recess, a substrate connection part which is exposed below the bottom plate part so as to be connected to the substrate, and a holding part housed and held in the terminal press-in hole, and this holding part includes a terminal side first seal part and a terminal side second seal part which respectively configure a first seal part and a second seal part by adhering to the side faces of the terminal press-in hole.

Claims

1. A connector, comprising:

a terminal; and

a housing holding the terminal,

the connector being mounted on a substrate with a liquid potting agent applied thereto, wherein the housing includes a mating recess mating with a counterpart connector, along with a bottom plate part in which a terminal press-in hole with the terminal pressed therein is formed, the terminal includes a contact part contacting a counterpart terminal of the counterpart connector in the mating recess, a substrate connection part which is exposed below the bottom plate part so as to be connected to the substrate, and a holding part housed and held in the terminal press-in hole, and this holding part includes a terminal side first seal part and a terminal side second seal part which respectively configure a first seal part and a second seal part by adhering to the side faces of the terminal press-in hole.

2. The connector according to claim 1, wherein the holding part includes an anchor part which includes a protrusion part that bites the side faces of the terminal press-in hole between the first seal part and the second seal part.

3. The connector according to claim 1, wherein the terminal side first seal part and the terminal side second seal part are held in the terminal press-in hole by interference fitting.

4. The connector according to any claim 1, wherein the bottom plate part includes a reservoir of the potting agent formed on the top surface thereof.

5. The connector according to claim 1, wherein the terminal side first seal part has smaller dimensions in the width direction and the thickness direction than those of the terminal side second seal part, with the holding part pressed into the terminal press-in hole from upward to downward.

6. The connector according to claim 5, wherein the first burr housing part is formed so as to be adjacent to the upper end of the first seal part, while the second burr housing part is formed so as to be adjacent to the upper end of the second seal part.

7. The connector according to claim 1, wherein the terminal side first seal part has larger dimensions in the width direction and the thickness direction than those of the terminal side second seal part, with the holding part pressed into the terminal press-in hole from downward to upward.

8. The connector according to claim 7, wherein the first burr housing part is formed so as to be adjacent to the lower end of the first seal part, while the second burr housing part is formed so as to be adjacent to the lower end of the second seal part.

9. A connector assembly, comprising:

the connector according to claim 1; and

a counterpart connector which mates with the connector.
