Abstract

The invention provides a connector including a case, a body, a contact, and an annular joint. The case includes a through hole and a periphery of the through hole. The body includes a main body, the main body including a front portion received in the through hole of the case and a rear portion continuous with the front portion. The contact includes an intermediate portion held in the main body, a contact portion received in the through hole of the case, and a tail portion located on an opposite side of the intermediate portion from the contact portion. The annular joint is made of an insulating resin and joins the rear portion of the main body and the periphery of the through hole of the case.

Claims

1. A connector comprising:

a case including a through hole and a periphery of the through hole;

a body including a main body, the main body including a front portion received in the through hole of the case and a rear portion continuous with the front portion;

a contact including;

an intermediate portion held in the main body,

a contact portion received in the through hole of the case, and

a tail portion located on an opposite side of the intermediate portion from the contact portion; and

an annular joint of insulating resin to join the rear portion of the main body and the periphery of the through hole of the case.

2. The connector according to claim 1,

wherein the body further includes an abutting portion being provided on the rear portion of the main body and abutting the periphery of the through hole of the case, and

the abutting portion is embedded in the annular joint.

3. The connector according to claim 1, further comprising a shield case of tuboid shape possessing electrical conductivity, the shield case fitting in the through hole of the case, wherein

the front portion of the main body fits in the shield case,

the contact portion of the contact is enclosed by the shield case, and

the annular joint joins the rear portion of the main body, the periphery of the through hole of the case, and the shield case.

4. The connector according to claim 3, wherein the shield case includes:

a tuboid portion fitting in the through hole of the case, and

an engaging portion continuous with the tuboid portion, engaged with the periphery of the through hole of the case, and embedded in the annular joint.

5. The connector according to claim 4,

wherein the engaging portion is folded back toward the tuboid portion side and includes an end abutting the periphery of the through hole of the case.

6. The connector according to claim 3, wherein the shield case includes:

a tuboid portion fitting in the through hole of the case, and

a connecting portion being continuous with the tuboid portion and passing through the annular joint.

7. The connector according to claim 6,

wherein the connecting portion includes a curved portion curved in a generally U-shape or in a serpentine shape and embedded in the annular joint.

8. The connector according to claim 7, wherein

the connecting portion further includes:

a basal portion continuous with the tuboid portion and embedded in the annular joint, and

a distal portion projecting from the annular joint, and

the curved portion bridges the basal portion and the distal portion.

9. The connector according to claim 7, wherein

the curved portion includes:

first and second opposed portions facing each other, and

a protrusion provided on at least one of the first and second opposed portions, abutting the other of the first and second opposed portions, and creating a space between the first and second opposed portions, and

the resin of the annular joint is filled in the space.

10. The connector according claim 3, wherein the shield case includes:

a tuboid portion fitting in the through hole of the case, and

a fixing portion continuous with the tuboid portion and embedded in the annular joint.

11. The connector according to claim 2, wherein

the abutting portion comprises a plurality of abutting portions circumferentially arranged at intervals on and around an outer circumferential surface of the main body.

12. The connector according to claim 2, wherein

the abutting portion comprises a plurality of abutting portions circumferentially arranged at intervals on an around an outer circumferential surface of the main body,

the connector further comprises a shield case of tuboid shape possessing electrical conductivity, the shield case fitting in the through hole of the case and including:

a tuboid portion fitting in the through hole of the case, and

a fixing portion being continuous with the tuboid portion, fitting in between adjacent ones of the abutting portions, and being embedded in the annular joint,

the front portion of the main body fits in the shield case, and

the contact portion of the contact is enclosed by the shield case.

13. The connector according to claim 2,

wherein one of the periphery of the through hole of the case and the abutting portion is provided with a protrusion, and the other thereof is provided with a recess to fit over the protrusion.

14. The connector according to claim 1,

wherein the intermediate portion of the contact is embedded in the main body.

15. The connector according to claim 1, further comprising a shield cover possessing electrical conductivity to partially cover the case and the annular joint.

16. The connector according to claim 1,

wherein at least one of the case, the body, and the annular joint is made of a polyamide resin.

17. The connector according to claim 1, further comprising a ring-shaped gasket fitting around the case.

18. An electronic device comprising the connector according to claim 1.
