Abstract A pair of connector housing may be temporarily engaged so as to facilitate efficient connection operation thereof. A lever 15 is pivotably attached to a side wall of the male connector housing 11. When a female connector housing 12 is inserted into the male connector housing 11, a cam receiving protrusion 17 of a cover 13 resiliently deforms lugs 15a of a lever 15 to be opened, so that the cam receiving portion may be advanced through a portion 23 into a cam groove 16. After such advancement, lugs 15a are returned to their original position by means of resilient deformation, so that the portion 23 is engaged with the cam receiving protrusion 17, so as to prevent dislodgement of the cam receiving protrusion. The thickness of the portion 23 of the cam groove is selected so as to prevent dislodgement of the cam receiving protrusion. A restricting protrusion 24 is protruded laterally from the cam receiving protrusion 17. The restricting protrusion serves to urge the lugs 15 downwardly, so as to maintain constant amount of engagement between the cam receiving protrusion 17 and the portion 23 of the cam groove. Another restricting protrusion 25 extending in a vertical direction may be provided in the side wall 1 of the male connector housing 11.
A lever type connector comprising a pair of mating connector housings, one of the connector housings including a lever pivotably mounted thereon, the other of the connector housings including a cam receiving protrusion for engaging with a cam groove formed in the lever, whereby the pair of connector housings may be connected together or disconnected from one another by pivoting the lever so as to displace the cam receiving protrusion, characterized by: that said cam groove is formed into a closed configuration at the position thereof into which said cam receiving protrusion is advanced; and that the thickness of said portion of said cam groove is selected so that it permits advancement of said cam receiving protrusion thereinto by means of resilient deformation of said lever, while preventing dislodgement of said cam receiving protrusion, once advanced, by means of engagement between said cam groove and said can receiving protrusion.
Claim 2
Dependent Claim
53 words
A lever type connector in accordance with Claim 1 further comprising a restricting protrusion disposed between the vicinity to said cam receiving protrusion and said lever for maintaining a constant amount of engagement between said can receiving protrusion and said portion of said cam groove into which said cam receiving protrusion is advanced.
Claim 3
Dependent Claim
52 words
A lever type connector in accordance with Claim 1 wherein said connector housing provided with said lever includes in the side wall thereof a restricting protrusion for maintaining a constant amount of engagement between said cam receiving protrusion and said portion of said cam groove into which said caving protrusion is advanced.
