[0008]

[Problems to be solved by the device]

 In order to fix the terminal 10, first, the terminal 10 is inserted into the pin holder 20 and then the cap 30 is put on the pin holder 20, so that the pin holder 20 and the cap 30 must be separate parts. However, the process of inserting the terminal 10 and the process of covering the cap 30 had to be separate processes. To reduce the cost, it is required to reduce the number of parts and the assembly process.

[0009]

[Means for Solving the Problems]

 As illustrated in FIGS. 1 to 4, (1) As the terminal 50, one having a pair of opposed cut and raised portions 56 and a stopper 58 is used (FIG. 2). (2) The above-mentioned cap and pin holder are integrated from the beginning to form one part called the cap / pin holder assembly 60 (Fig. 3). (3) A terminal insertion square hole 72 having a width a narrower than the space a ′ of the cut and raised piece 56 is provided in the cap / pin holder combination 60, and the cut and raised piece for catching the cut and raised piece 56 is provided on the front surface of the square hole 72. A catch receiving portion 74 is formed, and a stopper receiving portion 76 for catching the stopper 58 is formed on the rear surface of the square hole 72 (FIG. 3).

[0010]

[Action]

 A cut-raised portion 56 and a stopper 58 are formed in the terminal 50, and a terminal insertion square hole 72 having a width narrower than that of the cut-raised portion 56 is provided in the pin holder portion 70 of the cap / pin holder combination 60. If a cut-and-raised receiving portion 74 for catching the cut-and-raised portion 56 is formed on the front surface of the square hole 72, and a stopper receiving portion 76 for catching the stopper 58 on the rear surface of the square hole 72 is formed, respectively. When the terminal 50 is pushed into the square hole 72 of the pin holder assembly 60 from the front end, the cut-and-raised portion 56 of the terminal 50 is pushed by the inner surface when passing through the square hole 72 so that the cut-and-raised angle becomes small. It deforms (so that the distance b ′ becomes smaller), but when it passes through the square hole 72, it returns to its original shape. Then, the cut-and-raised part 56 is caught by the receiving part 74 (FIG. 4), and the terminal 50 cannot be retracted. At the same time, the stopper 58 of the terminal 50 is caught by the receiving portion 76 of the cap / pin holder combination 60, and the terminal 50 cannot be advanced any further, and eventually the terminal 50 is fixed in the cap / pin holder combination 60.
