Connector
A connector includes a back housing, a front shell having a barrel portion and a grounding portion continuous with a rear portion of the barrel portion, and a cover shell. The cover shell has a contacting portion contacting a rear end upper portion of the front shell, a catching portion catching on the grounding portion, and a spring portion elastically deformed by catching of the catching portion. The elastic deformation of the spring portion causes the cover shell to contact the back housing while pressing the back housing frontward, and to contact the front shell while pressing the rear end upper portion of the front shell upward at the contacting portion.
1. A connector, comprising:
a contact composed of a first conductor and having a base portion, a contact portion extending from the base portion in a frontward direction in which the connector mates with a mating connector, for making contact with a mating contact, and a board connecting portion extending from the base portion in a downward direction in which a circuit board is positioned, and connected to the circuit board;
a front housing composed of a first dielectric and supporting the base portion with the contact portion exposed frontward;
a back housing composed of a second dielectric and supporting the base portion with the base portion held between the front housing and the back housing with the board connecting portion exposed downward;
a front shell composed of a second conductor and having a barrel portion enclosing the contact portion at a distance from the contact portion, and a grounding portion continuous with a rear portion of the barrel portion, widening downward, and connected to the circuit board; and
a cover shell composed of a third conductor, having a contacting portion contacting a rear end upper portion of the front shell from below, a catching portion catching on the grounding portion, and a spring portion elastically deformed by catching of the catching portion, the elastic deformation of the spring portion causing the cover shell to contact the back housing while pressing the back housing frontward, and to contact the front shell while pressing the rear end upper portion of the front shell upward at the contacting portion.
2. The connector of claim 1 , wherein the front shell has a tongue projecting rearward at the rear end upper portion of the front shell.
3. The connector of claim 2 , wherein the contacting portion has a recess receiving the tongue.
4. The connector of claim 3 , wherein the elastic deformation of the spring portion causes the cover shell to press the tongue received in the recess upward.
5. The connector of claim 1 , wherein the grounding portion has an extending portion extending laterally.
6. The connector of claim 5 , wherein the catching portion catches on the extending portion, causing the spring portion to deform elastically.
7. The connector of claim 6 , wherein the catching portion has a depression depressed upward.
8. The connector of claim 7 , wherein the catching portion catches on the extending portion at the depression.
9. The connector of claim 1 , wherein the spring portion has a shape projecting more frontward than the catching portion.
10. The connector of claim 9 , wherein the spring portion has a hole.
11. The connector of claim 10 , wherein catching of the catching portion causes the elastic deformation accompanied by deformation of the hole.
12. A connector, comprising:
a back housing formed of an insulative material;
a front shell having a barrel portion and a grounding portion continuous with a rear portion of the barrel portion; and
a cover shell having a contacting portion contacting a rear end upper portion of the front shell, a catching portion catching on the grounding portion, and a spring portion elastically deformed by catching of the catching portion, the elastic deformation of the spring portion causing the cover shell to contact the back housing while pressing the back housing frontward, and to contact the front shell while pressing the rear end upper portion of the front shell upward at the contacting portion.
13. The connector of claim 12 , wherein the front shell and the cover shell are each formed of a conductive material.
14. The connector of claim 12 , further comprising a contact having a base portion, a contact portion extending from the base portion, and a board connecting portion extending from the base portion.
15. The connector of claim 14 , wherein the barrel portion encloses the contact portion of the contact at a distance from the contact portion.
16. The connector of claim 14 , further comprising a front housing supporting the base portion with the contact portion exposed frontward.
17. The connector of claim 14 , wherein the back housing supports the base portion.
18. The connector of claim 17 , wherein the base portion is held between the front housing and the back housing with the board connecting portion exposed downward.
