Abstract
Abstract In a connector, a terminal lock member has openings in correspondence to terminal accommodating chambers formed in a connector housing. Of the vertical plates forming the terminal lock member, two are suitably selected. Each of the vertical plates thus selected has a first locking protrusion on one end face thereof, and a flexible arm formed by cutting a slit therein in such a manner that the flexible arm has a second locking protrusion on the other end fact. On the other hand, the connector housing has first and second engaging portions and in correspondence to the first and second locking protrusions. When the terminal lock member is inserted into the housing through the cavity to a temporary locking position where the openings align with the terminal accommodating chambers, the first locking protrusions are engaged with the first engaging portions, so that the terminal lock member is temporarily locked there. When the terminal lock member is further inserted into the housing from the temporary locking position to a real locking position where the terminal locking portions are engaged with terminals to prevent the latter from coming off backwardly, the second locking protrusions are engaged with the second engaging portions, whereby the terminal lock member is positively locked there.

Claim 1
Independent Claim
318 words
A connector comprising: a housing having a plurality of terminal accommodating chambers arranged therein, and a cavity formed in one outer wall thereof in such a manner that said cavity is extended vertically across partition walls of said terminal accommodating chambers; a terminal lock member including a plurality of vertical plates which combine to define a plurality of openings in correspondence to said plurality of terminal accommodating chambers and terminal lock portions in said openings which are engageable with terminals, a pair of said vertical plates being side plates respectively disposed at opposite ends of said terminal lock member; and terminal lock means for locking said housing and said terminal lock member by inserting said terminal lock member into said housing through said cavity to position said terminal lock member from a temporary locking position to a real locking position, wherein said terminal lock means includes: at least one of said side plates; a first terminal lock protrusion formed on one end face of said one side plate of said terminal lock member; a flexible arm formed on the other end face of said one side plate of said terminal lock member with a slit being formed between said first terminal lock protrusion and said flexible arm, said flexible arm having a second terminal lock protrusion protruded from said flexible arm; and wherein said housing includes: a first engaging portion, formed on said housing, engageable with said first terminal lock protrusions when said terminal lock member is inserted into said housing to said temporary locking position where said openings thereof are substantially aligned with said terminal accommodating chambers; and a second engaging portion, formed on said housing, engageable with said second terminal lock protrusion when said terminal lock member is moved from said temporary locking position to said real locking position where said terminal locking portions engage with said terminals to prevent said terminals from moving in backwardly.
Claim 2
Dependent Claim
318 words
A connector comprising: a housing having a plurality of terminal accommodating chambers arranged therein, and a cavity formed in one outer wall thereof in such a manner that said cavity is extended vertically across partition walls of said terminal accommodating chambers; a terminal lock member including a plurality of vertical plates which combine to define a plurality of openings in correspondence to said plurality of terminal accommodating chambers and terminal lock portions in said openings which are engageable with terminals, a pair of said vertical plates being side plates respectively disposed at opposite ends of said terminal lock member; and terminal lock means for locking said housing and said terminal lock member by inserting said terminal lock member into said housing through said cavity to position said terminal lock member from a temporary locking position to a real locking position, wherein said terminal lock means includes: at least one of said side plates; a first terminal lock protrusion formed on one end face of said one side plate of said terminal lock member; a flexible arm formed on the other end face of said one side plate of said terminal lock member with a slit being formed between said first terminal lock protrusion and said flexible arm, said flexible arm having a second terminal lock protrusion protruded from said flexible arm; and wherein said housing includes: a first engaging portion, formed on said housing, engageable with said first terminal lock protrusions when said terminal lock member is inserted into said housing to said temporary locking position where said openings thereof are substantially aligned with said terminal accommodating chambers; and a second engaging portion, formed on said housing, engageable with said second terminal lock protrusion when said terminal lock member is moved from said temporary locking position to said real locking position where said terminal locking portions engage with said terminals to prevent said terminals from moving in backwardly.
