る。 Generally, for printed circuit boards, a terminal with a lead wire crimped is mounted inside a housing, and the housing is fitted to a wafer assembly attached to the printed circuit board to connect the printed circuit board and the lead wire. Connectors often use tin-plated connecting pins and terminals. However, when the board or lead wire to which the connector is attached vibrates due to an external shock, the vibration is transmitted to the terminal, and slight sliding tends to occur between the terminal and the pins.
Due to this slight sliding, the contact area between the terminal and the pin generates heat, which oxidizes the tin and causes a connection failure. This is the deterioration of connector characteristics due to slight sliding wear.

うまでもない。 To explain the present invention based on the drawings, as shown in FIG. After fixing by soldering or crimping, the terminal 3 is housed in the housing 1. On the other hand, a connecting pin 4 embedded in a flexible synthetic resin wafer assembly 2
is soldered and fixed 11 to a metal conductive foil 10 of a printed circuit board 9. and contact connection 4a of pin 4
is inserted into the inner circumferential wall of the connecting portion 3a of the terminal 3 and is connected in contact therewith. Figure 1 is a top view of the terminal 3 and pin 4 in a contact-connected state, and the second
The figure is a side sectional view thereof. As shown in these figures, when the housing 1 with the terminal 3 attached is fitted to the wafer assembly 2, the housing 1 and the wafer assembly 2 are connected to the housing 1 by the extension locking part 5 of the wafer assembly.
is engaged with the engaging portion 6 of the housing to prevent it from coming off in the direction of arrow A, thereby preventing the housing from coming off from the wafer assembly. The difference in this invention from conventional connectors is that the locking part 5 of the wafer assembly has the function of locking the wafer assembly and the housing, and also the function of fixing the terminal 3 and the housing 1. be. When the housing 1 is fitted into the wafer assembly 2 as shown in the figure, the locking part 5 of the wafer assembly penetrates into the housing and is locked with the upper engaging part 6 of the housing. At the same time, the tip 5a of the locking part 5 of the wafer assembly presses the wire covering crimping part 7 of the terminal against the housing, fixing the terminal and the housing. In addition, in the above,
Locking part 5 and terminal 3 to prevent housing from coming off
Although an example has been described in which the pressing tip 5a is also used, it goes without saying that the two may be separated and provided separately.

極めて少ないという効果を有している。 The printed circuit board connector according to the present invention has a fixed housing and terminal, so vibrations from the printed circuit board and wires are not easily transmitted to the terminal, and compared to conventional connectors, it has excellent reliability against slight sliding wear. This has the effect that the rate at which characteristic deterioration occurs is extremely low.
