Abstract
Abstract An electrical connector consisting of a housing, a cover and a retainer is provided. The housing is provided with terminal-accommodating chambers. The cover is attached to the housing so as to slide between a "closed" position and a "opened" position. Moving from its temporary engagement position to its formal engagement position, the retainer engages with the terminal metals to prevent them from slipping out of the terminal-accommodating chambers. When the terminal metals are not inserted into the terminal-accommodating chambers perfectly, the retainer restricts the movement of the cover from the closed position to the opened position, interfering with the terminal metals, so that it allows an operator to detect that the terminal metals are in semi-inserting condition. In order to secure this detection, the cover is provided with a rib and the housing is provided with a dovetail groove which engages with the rib.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
277 words
An electrical connector for connecting a terminal metal having a contact portion to be connected with a terminal section of a board, said connector comprising: a housing having a plurality of terminal-accommodating chamber formed therein for accommodating and engaging the terminal metal in condition of exposing the contact portion, a cover attached to said housing so as to slide between a closed position where said cover closes the contact portion and an opened position where said cover opens the contact portion when said terminal metal is connected to the terminal section of the board, said cover having a dovetail groove formed so as to extend in the sliding direction of the cover, and a retainer having a pair of sidewalls, a flexible detection plate between said sidewalls and a detection projection formed on said detection plate, said retainer being capable of engaging with the terminal metal in the terminal-accommodating chamber by its movement from its temporary engagement position to its formal engagement position thereby to prevent said terminal metal from slipping out of the terminal-accommodating chamber, said retainer also abutting on the terminal metal when it is not inserted into the terminal-accommodating chamber perfectly thereby to obstruct the movement of said cover from the closed position to the opened position, whereby it allows an operator to detect that the terminal metal is not accommodated in the terminal-accommodating chamber perfectly, wherein said housing is provided with a first rib which slidably engages with said dovetail groove, while said retainer is provided with a second rib which is formed on said flexible detection plate to slidably engage with said dovetail groove when said cover moves to the opened position.

An electrical connector for connecting a terminal metal having a contact portion to be connected with a terminal section of a board, said connector comprising: a housing having a plurality of terminal-accommodating chamber formed therein for accommodating and engaging the terminal metal in condition of exposing the contact portion, a cover attached to said housing so as to slide between a closed position where said cover closes the contact portion and an opened position where said cover opens the contact portion when said terminal metal is connected to the terminal section of the board, said cover having a dovetail groove formed so as to extend in the sliding direction of the cover, and a retainer having a pair of sidewalls, a flexible detection plate between said sidewalls and a detection projection formed on said detection plate, said retainer being capable of engaging with the terminal metal in the terminal-accommodating chamber by its movement from its temporary engagement position to its formal engagement position thereby to prevent said terminal metal from slipping out of the terminal-accommodating chamber, said retainer also abutting on the terminal metal when it is not inserted into the terminal-accommodating chamber perfectly thereby to obstruct the movement of said cover from the closed position to the opened position, whereby it allows an operator to detect that the terminal metal is not accommodated in the terminal-accommodating chamber perfectly, wherein said housing is provided with a first rib which slidably engages with said dovetail groove, while said retainer is provided with a second rib which is formed on said flexible detection plate to slidably engage with said dovetail groove when said cover moves to the opened position.
Claim 3
Dependent Claim
121 words
An electrical connector as claimed in claim 1, wherein said housing has a connection part for exposing the contact portion of the terminal metal, said connection part being provided with said first rib, and support walls for supporting said retainer in both the temporary engagement position and the formal engagement position; said contact portion of the terminal metal is closed by said cover closing said connecting part of said housing; when said retainer is in the temporary engagement position, said cover is prevented from moving to the opened position; and wherein when said retainer is in the formal engagement position, said cover is slid and moved to the opened position, overlapping with said retainer, whereby said connection part can be opened.
Claim 4
Dependent Claim
36 words
An electrical connector as claimed in claim 2, wherein said cover is moved from the closed position to the opened position by a connection operation between the terminal section of the board and the terminal metal.
