保するため、ロック腕と係合突起から成るロック手段を
有し、ロック腕が係合突起に係合する際の操作感触と外
見から嵌合の確認を得るようにしていた。An electrical connector for electrically connecting a pair of built-in terminals by fitting a female and a male connector has a locking means composed of a locking arm and an engaging protrusion in order to secure the connected state, and the locking arm is engaged. It has been attempted to obtain confirmation of the fitting from the operation feeling and the appearance when engaging the mating protrusion.
しかし、操作感触はコネクタ嵌合時の緩急の度合や使用
雰囲気、個人差などにより異なり、目視にも誤認や見落
しのある場合があり、いずれも嵌合の確認手段としては
確実性に欠ける。However, the feeling of operation varies depending on the degree of slackness at the time of fitting the connector, the atmosphere in which the connector is used, individual differences, etc., and may be mistakenly visually overlooked or overlooked.
そこで、特開平１−241778号には第７図a,bに示すよう

接続に大きな嵌合力を要し、作業に難渋する場合があ
る。In electrical connectors such as those shown in Figs. 7a and 7b, male and female connectors are used.
Since the fitting operation of a and d and the operation of locking the lock plate b are independent of each other, there is a possibility that the worker finishes the work while forgetting to lock the lock plate b. Further, due to the multi-pole of the connector (increased number of connector terminals), a large fitting force is required for fitting and connecting the male and female terminals, which may make the work difficult.
本発明は、上記の問題点に着目してなされたものであ

An eccentric cam groove is provided on both sides of the connector, and a cam lever is rotatably provided on both sides of the connector. The eccentric cam groove engages with the pin to engage and disengage both connectors by rotating the cam lever. An electric connector provided with an operation plate for connecting both cam levers, wherein the other connector is provided with an elastic member for urging the operation plate upward to erect the cam lever, and to disengage the eccentric cam groove. The gutter wall is formed as a wide surface that engages with the pin when the cam lever is in the upright position.
