摘要

In a lever type connector 21 in which a female connector housing 25 is provided with a fitting operation lever 29 for pulling a fitting pin 27 projected on a male connector housing 23 in a side of an end of a pin guide groove 30 with rotating operation of the fitting operation lever 29, the side of the end of the pin guide groove 30 is provided with a spring part 61 which makes contact with the fitting pin 27 of the inside of the pin guide groove 30 in an elastic deformation state and regulates relative movement of the fitting operation lever 29 and the fitting pin 27 when fitting between the connector housings 23, 25 is completed.

主权项

1. A lever type connector, comprising:
a first connector housing receiving a first connecting terminal; a second connector housing receiving a second connecting terminal connected to the first connecting terminal and fitted into the first connector housing; a fitting pin projected on an outside surface of the first connector housing; and a fitting operation lever rotatably attached to a side surface of the second connector housing and having a pin guide groove which the fitting pin is to be entered; wherein the pin guide groove including a groove starting opening which the fitting pin enters in an early stage of fitting between the first connector housing and the second connector housing, and a pull-in guide surface for pulling the fitting pin in a side of an end of the pin guide groove with rotating of the fitting operation lever, and a push-out guide surface in opposition to the pull-in guide surface; both of the connector housings are fitted by relatively moving the fitting pin from the groove starting opening toward the end of the pin guide groove by rotating and operating the fitting operation lever; the side of the end of the pin guide groove is provided with a spring part which makes contact with the fitting pin of an inside of the pin guide groove in an elastic deformation state and regulates relative movement of the fitting operation lever and the fitting pin when fitting between both of the connector housings is completed; and a width of the pin guide groove is set larger than an outside diameter of the fitting pin over a whole length of the pin guide groove at a separation distance between the pull-in guide surface and the push-out guide surface.
