Problems solved by technology
[0010] However, in the existing connector, because the lower end of the arm member 828 formed with the rear locking protrusion 828a is not fixed and is in a free state, for example, when the terminal locking member 821 is moved in the up and down direction to remove the cover 831 or terminal 851, the free lower end may be abutted or stuck with other components, which can damage the arm element 828
[0011] In addition, when the lower end of the arm member 828 is connected to the body of the terminal locking member 821 to prevent damage to the arm member 828, because the flexibility of the arm member 828 is lost, the locking protrusion 828a and the locking portion 818 of the housing 811 are engaged. Engagement and disengagement cannot be performed smoothly

The present invention provides a highly reliable connector in which the terminal locking element is strong and highly flexible, can be easily locked and released from the housing, and can reliably maintain the locked state. The housing includes a terminal accommodating hole capable of accommodating a terminal inside and a locking element accommodating recess capable of accommodating a terminal locking element inside. The terminal locking element includes: a first locking protrusion, which engages with the first locking portion of the housing when the terminal locking element is in a temporary locking position where the terminal is accommodated in the locking element accommodating recess and the terminal can be inserted into or disengaged from the terminal accommodating hole. and the second locking protrusion, when the terminal locking element is in the final locking position where the terminal locking element is accommodated in the locking element receiving recess and the terminal cannot be inserted into or disengaged from the terminal receiving hole, it engages with the second locking part of the housing; Two locking protrusions are formed on the wide part of the leaf spring element. The leaf spring element is a double-beam-shaped leaf spring element with both ends fixed and the middle free. One end side of the leaf spring element is a narrow part, and the other end side is a narrower part than the other Wide wide part.
Description
[0001] related application [0002] This application claims priority from Japanese application JP2017-042982 filed March 7, 2017, which is hereby incorporated by reference in its entirety. technical field [0003] The invention relates to a connector. Background technique [0004] Generally, in order to securely hold a terminal connected to an end of an electric wire such as a cable within a housing, a connector provided with a holding element, ie, a terminal locking element, has been proposed (for example, see Patent Document 1). [0005] Figure 9 It is a partially enlarged view showing a locking mechanism of a conventional terminal locking element. [0006] exist Figure 9 Among them, 811 is a housing of a connector, and has a terminal accommodating hole 816 for accommodating a terminal 851 , and the terminal 851 is connected to an end of a wire 891 . The terminal receiving hole 816 penetrates the housing 811 in the front-rear direction, and a mating terminal protruding...
