Abstract

A slanted DIMM connector (10) includes an insulative housing (12) defining a central slot (13) for receiving a module therein and a pair of ejectors (16) rotatably positioned within a pair of corresponding towers (14) adjacent two opposite ends of the housing (12). Three support blocks (18) extend forward from a center portion and two opposite end portions wherein each of the support blocks (18) about the end portion has a cut-off (36) in alignment with the tower (14). When the two slanted DIMM connectors (10) are closely side by side arranged on the PC board (100) in a front-to-end direction, the outermost upper edge (40) of the tower (14) of the front connector (10) is substantially aligned with a vertical plate (38) of the cut-off (36) of the adjacent rear slanted DIMM connector (10), so that the rear connector (10) can be directly upward moved from the PC board (100) without interference with the raised tower (14) or any portion of the front connector (10).

Claims

1. A slanted card edge connector assembly including at least two connectors closely side by side mounted on a PC board,

each of said connectors comprising:

an elongated insulative housing defining a central slot for receiving a card therein;

two raised towers disposed adjacent two opposite ends of the housing;

at least a standoff support positioned about a front bottom portion of each of said towers;

wherein

said support further includes a cut-off generally in alignment with the corresponding tower so as not to interfere with an upper portion of the aligned tower of another adjacent connector which is positioned side by side closely in front of said connector, thereby allowing the connector to be removed from the PC board for repairing without removing said another adjacent connector in front thereof.

2. The assembly as defined in claim 1, wherein plural blocks are formed under front bottom portions and rear bottom portions of the housing.

3. The assembly as defined in claim 1, wherein the cut-off defines a vertical plane which is generally aligned with outermost edge of the upper portion of the aligned tower of said another adjacent connector.

4. A method for mounting at least two slanted type card edge connectors closely side by side on a PC board while allowing of removing anyone connector thereof without interference occurring thereabout, the steps comprising:

providing at least two slanted card connectors mutually closely side by side mounted on the PC board in a front-to-end direction wherein each said connector has an elongated housing including a pair of raised towers at two opposite ends, and a support block is integrally formed under each said tower with a cut-off about a front bottom portion of the tower;

arranging an outermost upper edge of the tower of the front connector not to project over, in a vertical direction, an edge of said cut-off of the rear connector but to project over, in said vertical direction, a front edge of the corresponding support block; and

vertically upward removing the rear connector from the PC board without interference between an upper portion of said raised tower of the front connector and the front bottom portion of the rear connector wherein the support block of the rear connector passes aside the outermost edge of the tower of the front connector during upward movement of the rear connector with regard to the front connector.

5. The method as defined in claim 4, wherein each tower further includes an rotatable ejector therein whereby upward moving of the rear connector from the PC board is implemented when said ejector is in an open unlocked manner.

6. A slanted type connector comprising:

an elongated insulative housing having a base plane angular with a PC board on which the connector is mounted;

at least one raised tower positioned adjacent one end of the housing and extending along a same angular direction with the housing;

at least a support block extending in both forward and rearward directions for providing an enlarged standing area of the housing;

an offset surface, which is substantially recessed from a front edge of said support block, aligned with and formed on a lower portion of the tower whereby two of said slanted connectors are side by side, in a front-to-end direction, closely mounted on a PC board with the an outermost edge of the tower of the front connector projecting not over the offset surface of the rear connector in a vertical direction but over the front edge of said corresponding support block of the rear connector in said vertical direction thus allowing the rear connector to be removed from the PC board for repairing without removing the front connector.

7. The connector as defined in claim 6, wherein said offset surface is formed by a cut-off which is generally removed from the support block.

8. The connector as defined in claim 6, wherein said offset surface is perpendicular to the PC board on which the connector is mounted.

9. The connector as defined in claim 6, wherein the outermost edge of the raised tower of the front connector is generally aligned with the offset surface of the rear connector in the vertical direction.
