Abstract

It is aimed to prevent a reduction of contact reliability. A card edge connector (A) includes a first housing ( 10 ) formed with a board accommodation space ( 16 ) open forward, terminal fittings ( 17 ) provided in the first housing ( 10 ) and formed with resilient contact portions ( 18 ) projecting toward the board accommodation space ( 16 ), a second housing ( 20 ) including a circuit board ( 23 ) to be inserted into the board accommodation space ( 16 ) from front of the first housing ( 10 ), and guide slopes ( 36 ) made of synthetic resin, provided to cover a leading edge of the circuit board ( 23 ) in an inserting direction into the board accommodation space ( 16 ) and inclined with respect to the inserting direction into the board accommodation space ( 16 ).

First claim

The invention claimed is:

1. A card edge connector, comprising:
a first housing formed with a board accommodation space open forward,
a terminal fitting provided in the first housing and formed with a resilient contact portion projecting toward the board accommodation space; and
a second housing including a circuit board to be inserted into the board accommodation space from front of the first housing;
the second housing including a board holding member made of a first synthetic resin and configured to surround an area of the circuit board except a leading end part in an inserting direction and a guide member formed from a second synthetic resin that is different than the first synthetic resin and less rigid than the first synthetic resin, the guide member having a pair of left and right side frame portions arranged before a front surface of the board holding member and a front frame portion coupling front ends of the side frame portions; and
the front frame portion including a guide slope provided to cover a leading edge of the circuit board in the inserting direction into the board accommodation space and inclined with respect to the inserting direction into the board accommodation space.

2. A card edge connector, comprising:
a first housing formed with a board accommodation space open forward,
a terminal fitting provided in the first housing and formed with a resilient contact portion projecting toward the board accommodation space; and
a second housing including a circuit board to be inserted into the board accommodation space from front of the first housing;
the second housing including a board holding member made of synthetic resin and configured to surround an area of the circuit board except a leading end part in an inserting direction and a guide member having a pair of left and right side frame portions, the pair of side frame portions extending along both left and right side edges of the circuit board and a front frame portion coupling front ends of the side frame portions, the front frame portion extending along the leading edge of the circuit board, the front frame portion including a guide slope provided to cover a leading edge of the circuit board in the inserting direction into the board accommodation space and inclined with respect to the inserting direction into the board accommodation space; and
the guide member further including a rear frame portion extending along a rear edge of the circuit board.

3. The card edge connector of claim 2 , wherein the guide member is a component separate from the board holding member.

4. The card edge connector of claim 3 , wherein the guide slope is formed of a synthetic resin material containing no glass fiber.

5. The card edge connector of claim 4 , wherein the guide member is formed with a pair of covering portions configured to sandwich a leading edge part in the inserting direction of the circuit board in a plate thickness direction.

6. The card edge connector of claim 5 , wherein the covering portion is formed with a guiding slope inclined with respect to the inserting direction of the circuit board.

7. The card edge connector of claim 6 , wherein a part of the guide member except a leading end part in the inserting direction is embedded in the board holding member.

8. The card edge connector of claim 1 , wherein the guide slope is formed of a synthetic resin material containing no glass fiber.

9. The card edge connector of claim 1 , wherein the guide member is formed with a pair of covering portions configured to sandwich a leading edge part in the inserting direction of the circuit board in a plate thickness direction.

10. The card edge connector of claim 1 , wherein the covering portion is formed with a guiding slope inclined with respect to the inserting direction of the circuit board.

11. The card edge connector of claim 1 , wherein a part of the guide member except a leading end part in the inserting direction is embedded in the board holding member.
