Claims

[Scope of Claim for Utility Model Registration] (1) A connector housing having a recess into which the card edge of the card board is inserted and an elastic contact piece that contacts the contact point of the card edge, and a card edge insertion guide part of the card board. a card board insertion guide member slidably fitted into the recess of the connector housing;
an elastic means that is interposed between the connector housing and the card board insertion guide member and constantly presses the card board insertion guide member outward; and an elastic means that is formed between the connector housing and the card board insertion guide member; A locking means cooperates with the elastic means to hold the elastic contact piece and the contact point of the card edge in a contact position when the card board is inserted; A card edge connector comprising elastic contact piece connecting means for displacing the contact piece to maintain contact between the contact point of the card edge and the elastic contact piece. (2) The locking means includes a ball guide groove formed in one of the opposed parts of the connector housing and the card board insertion guide member, a ball holding part formed in the other part, and a ball guide groove and a ball holding part formed in the other part. 2. The card edge connector according to claim 1, further comprising a ball movably interposed in the card edge connector. (3) The lock means constantly engages a locking portion provided on the card board insertion guide member, a lock operating portion attached to the connector housing to removably engage with the locking portion, and a lock operating portion. Claim 1 comprising a locking elastic means that presses toward the stop portion.
Card edge connector listed. (4) The locking means is composed of a guide groove formed in one of the opposing parts of the card board insertion guide member of the connector housing, and a lock pin that projects from the other side and guides and moves within the guide groove. The card edge connector according to claim 1. (5) The card edge connector according to any one of claims 1 to 4, wherein the elastic contact piece connecting means is a tapered groove formed in the card board insertion guide member. (6) The elastic contact piece connecting means is pivotably attached to the connector housing, and has engaging claws and elastic contacts at both ends that can engage with engaging portions formed on the card board insertion guide member, respectively. The card edge connector according to any one of claims 1 to 4, which is a lever-like connecting member having a pressing portion that presses into engagement with the piece.
