Connector with header connector and socket connector that are mechanically and electrically connected with each other

1. An electrical connector assembly comprising:

a header connector having a header housing and at least a header contact;

the housing having a wall along an insert direction;

the header contact being bent so that both faces of the wall are sandwiched between the bent two parts of the header contact, and then fixed on the wall;

a socket connector having at least a resilient socket contact and a socket housing having a connection cavity formed so that the wall fixing the header contact is inserted into the cavity and pulled out thereof along the insert direction; and,

the socket contact including a contact section bent so that the header contact inserted into the cavity is sandwiched between both ends of the contact section and the ends come in contact with the header contact;

wherein the socket contact further includes a fixed section that is formed to extend from the tip of one end of the contact section so that a part of the fixed section is arranged in parallel with the one end, said part of the fixed section existing at the tip side of the fixed section;

the socket housing is formed with a pair of facing retention grooves and a pair of facing guiding grooves along the direction on facing surfaces in the cavity, respectively, said socket housing sandwiching and retaining both sides of the part of the fixed section between the retention grooves, said socket housing also sandwiching and receiving both sides of the one end of the contact section between the guiding grooves so that the one end of the contact section can only move along said facing surfaces in the cavity; and,

each of the guiding grooves has a width wider than the thickness of the one end of the contact section and has a buffer gap at a side of the neighboring retention groove when the wall fixing the header contact is not inserted into the cavity,

all of the one end of contact section being movable to a side of the part of the fixed section through the buffer gap.

2. The connector of claim 1 , wherein

the socket housing further comprises a through slot along the insert direction, said slot having facing surfaces as said facing surfaces in the cavity and is formed at the bottom and another facing surfaces in the cavity;

the socket contact is put in the slot; and

the retention grooves and the guiding grooves are opened toward the insert direction.

3. The connector of claim 1 , wherein:

the both sides of the one end of the contact section are formed with a pair of guide projections that are guided along the guiding grooves and substantially come in contact with the guiding grooves, respectively,

while the both sides of the part of the fixed section are formed with a pair of guide projections guided along the retention grooves and a pair of retention projections pressed into the retention grooves, respectively.

4. The connector of claim 1 , wherein:

the header housing further includes another wall along the insert direction, the end face of the another wall being formed with a rack that sticks out along the insert direction; and

the socket housing further includes a receiving cavity in which said another wall is received, the bottom of the receiving cavity being formed with a pair of rack stoppers that stick out along the insert direction so that the tip of the rack is sandwiched between the stoppers when the wall fixing the header contact is inserted into the connection cavity.
