## Abstract

A printed circuit board connector is equipped with a housing and plurality of contacts. The housing has an insertion chamber 11 inserted by the mating-side connector, and a plurality of contact-insertion holes inserted by the contacts. The contact has a base portion, a contact-connecting portion that connects with a mating-side contact, and a lead portion that is solder-bonded to the printed circuit board. The base portion and the housing have a contact lance and level that engage with each other so that the contact does not move in an insertion direction to the contact insertion hole or a reverse direction, and the contact lance and level swingably hold the base portion inside the contact-insertion hole so that the lead portion approaches and separates from the printed circuit board surface.

## Claims

### Claim 1

A printed circuit board connector equipped with a housing, and a plurality of plate-shaped connectors arranged in parallel in the housing, wherein
the housing includes
an insertion chamber one surface thereof open to enable insertion of a mating-side connector;
a contact-insertion hole open in a direction opposite to the insertion chamber opening, penetrating the insertion chamber, and can be inserted therein by the connectors,
the connectors
include a base portion held inside the connector-insertion hole;
contact-connecting portion a width thereof being narrower than the base portion, disposed to project into the insertion chamber, extending to one end side from the base portion;
a lead portion, one end side of the base portion bent and extending toward a bottom surface side of the housing, further bent to extend in parallel to the contact-connecting portion in a direction opposite to the contact-connecting portion, solder-bonded to a surface of the printed circuit board; and
locking means that mutually engage the contact base portion and the housing so that the contact does not move in an insertion direction to the contact insertion hole or a reverse direction; and
the locking means swingably holds the contact base portion inside the contact insertion hole so that lead portions approach and separate from the printed circuit board surface.

### Claim 2 (depends on 1)

The printed circuit board connector according to claim 1, wherein
the locking means includes
a first engaging member that is equipped with a contact lance extending substantially parallel to the base portion from one end side of the base portion to another end side, equipped at a leading end portion with a hook-shaped latching piece; and
a second engaging member that communicates with the contact-insertion hole, and is equipped in the housing with a level that is engaged by the latching piece, formed with an elongated hole that is inserted by the contact lance, formed at a back of the elongated hole.

### Claim 3 (depends on 1)

The printed circuit board connector according to claim 1, wherein
the locking means includes
a third locking means that projects from another face of the housing, and disposes on the a housing lance that turns over to oppose an inner wall of the contact insertion holes, and
a fourth locking means partially formed in the base portion, that disposes on the contact a rectangular notch portion that can be engaged by a leading end portion of the housing lance.

### Claim 4 (depends on 1)

The printed circuit board connector according to claim 1, wherein
a plurality of contacts-insertion holes is disposed, and includes
a first contact insertion hole group arranged with a plurality of the contact-insertion holes in a line at a top level of another surface of the housing; and
a second contact insertion hole group arranged with a plurality of the contact-insertion holes in a line at a bottom level of another surface of the housing;
the contacts are disposed in plurality,
a first contact inserted into each contact-insertion hole of the first contact insertion hole group, and whose leg portion from the base portion to the lead portion is long; and
a second contact inserted into each contact-insertion hole of the second contact insertion hole group, and whose leg portion from the base portion to the lead portion is short;
an end portion of the base portion including the leg portion and the lead portion on the first contact and the second contact are alternately arranged.
