Abstract

A connector includes a connector body having an insertion space for receiving its counterpart connector. The connector body includes a synthetic-resin housing for retaining contacts, and a metallic shell. A part of the insertion space is defined by an upper plate of the shell. The upper plate of the shell has extensions extended therefrom along corresponding side walls of the housing. The extensions include legs soldered to a conductive portion on a printed wiring board surface. The legs are outwardly extended and confined in an outline of the connector body as viewed in plan.

Claims

1. A connector for printed wiring board having an insertion space for receiving its counterpart connector comprising:

a connector body mounted on a printed wiring board, including,

1) a synthetic-resin housing for retaining a plurality of contacts, the housing including a pair of side walls; and

2) a metallic shell as an electromagnetic shield covering the housing, the shell being integrally formed from a metal sheet, including

a) an upper plate defining a part of the insertion space,

b) a first pair of extensions, each extension individually extended directly from said upper plate along one of the side walls of the housing, the pair of extensions correspondingly including a pair of legs extending outwardly on a surface of the printed wiring board and soldered to a conductive portion on the printed wiring board surface,

c) a lower plate extending on the printed wiring board, and having first and second side edges,

d) a second pair of extensions, each extension individually directly extending from either the first or second side edges of said lower plate along one of the side walls of the housing, and

e) a front plate defining an insertion opening to the insertion space,

wherein the upper and lower plates are connected via the front plate, and

each of the first and second extensions includes engagement parts, each of which engages one of the side walls of the housing, the engagement preventing rotation of the upper and lower plates about the front plate.

2. A connector for printed wiring board according to claim 1, wherein the pair of side walls are each formed with a recess at a lower part of an outside surface thereof, and

wherein the pair of extensions correspondingly include a pair of bent portions inwardly projected and accommodated in the corresponding recesses of the side walls.

3. A connector for printed wiring board according to claim 2, wherein the pair of bent portions correspondingly include the pair of legs.

4. A connector for printed wiring board according to claim 2, wherein the pair of bent portions correspondingly include a pair of grooved portions laterally opened.

5. A connector for printed wiring board according to claim 1, wherein the first pair of extensions is a pair of resilient tongues individually extended upward from said lower plate along the corresponding side walls of the housing.

6. A connector for printed wiring board according to claim 5, wherein the pair of resilient tongues correspondingly have a pair of pressure pieces extended from top ends thereof along corresponding upper surfaces of the side walls of the housing, and

wherein the side walls of the housing are correspondingly clamped between the pair of pressure pieces and the lower plate.

7. A connector for printed wiring board according to claim 5, wherein the pair of resilient tongues are formed with engagement holes for engagement with corresponding projections formed on the side walls of the housing, thereby preventing the shell from slipping away from the housing.

8. A connector for printed wiring board according to claim 1, wherein the shell includes a pair of resilient tongues individually extended along the corresponding side walls of the housing, and

wherein the pair of resilient tongues are formed with engagement holes for engagement with corresponding projections formed on the side walls of the housing, thereby preventing the shell from slipping away from the housing.

9. A connector for printed wiring board according to claim 1, wherein the upper plate of the shell is provided with a rib.

10. A connector for printed wiring board according to claim 9, wherein the rib projects into the insertion space and extends along a direction of insertion of the counterpart connector.

11. A connector for printed wiring board according to claim 10, wherein the rib slides in a groove of the counterpart connector in being inserted in the insertion space, thereby guiding the counterpart connector in insertion.

15. A connector according to claim 1, wherein the engagement parts of the first extensions further engage a lower surface of the housing, in addition to the side walls of the housing.

16. A connector according to claim 1, wherein the engagement parts of the second extensions further engage an upper surface of the housing, in addition to the side wails of the housing.

12. An electrical connector, comprising:

a connector body, including,

1) a housing for retaining a contact, said housing including a pair of side walls; and

2) a shell covering the housing, including

a) an upper plate defining a part of an insertion for receiving a complementary connector,

b) a first pair of extensions, each extension individually extended directly from said upper plate along one of said side walls of said housing,

c) a lower plate,

d) a second pair of extensions, each extension individually directly extending from said lower plate along one of said side walls of said housing, and

e) a front plate, defining an insertion opening in communication with the insertion space, that connects said upper plate and said lower plate,

wherein each of said first and second extensions engages one of said side walls of said housing in opposite directions, the engagement preventing rotation of said upper and lower plates about said front plate.

13. A connector for printed wiring board according to claim 12, wherein the engagement parts of the first extensions further engage a lower surface of the housing, in addition to the side walls of the housing.

14. A connector for printed wiring board according to claim 12, wherein the engagement parts of the second extensions further engage an upper surface of the housing, in addition to the side walls of the housing.

17. A shell for a connector, comprising:

a) an upper plate defining a part of an insertion for receiving a complementary connector,

b) a first pair of extensions, each extension individually extendable directly from said upper late along a side wall of a housing to be held in said shell,

c) a lower plate,

d) a second pair of extensions, each extension individually directly extendable from said lower plate along one of the side walls of the housing, and

e) a front plate defining an insertion opening in communication with the insertion space that connects said upper plate and said lower plate,

wherein each of the first and second extensions includes engagement parts, each of which is engageable with one of the side walls of the housing in opposite directions, the engagement preventing rotation of the upper and lower plates about the front plate.

18. A connector according to claim 17, wherein the

engagement parts of the first extensions are further engageable with a lower surface of the housing, in addition to the side walls of the housing.

19. A connector according to claim 17, wherein the engagement parts of the second extensions are further engageable with an upper surface of the housing, in addition to the side walls of the housing.
