Substantially semicircular grooves 15 into which one ends 22a of the male terminals 22 to be described later are fitted are formed in parallel at regular intervals at ends 14a of the connector mounting recesses 14 in the longitudinal direction. On the upper surface 13b side of the printed circuit board 13, a pattern (circuit) 16 extending to around each groove 15 is formed. In addition, substantially triangular engaging projections (engaging portions) 17 are integrally formed on opposite side portions 14b, 14b of each connector mounting concave portion 14 of the printed circuit board 13.

As shown in FIG. 1 and FIG.
Is a box-shaped female connector housing 21 made of synthetic resin.
And a plurality of substantially U-shaped male terminals (terminals) 22 projecting in parallel from inside to outside of the connector housing 21. Above the center of the outer surface of the front wall 21a of the connector housing 21, a rectangular plate-shaped
b is integrally formed. This rectangular plate-shaped flange 21b
Are formed with terminal through holes 21c through which one end 22a of each male terminal 22 penetrates. Further, a pair of upper and lower guides 23, 23 for slidably engaging the opposite side portions 14b, 14b of the connector mounting recess 14 are integrally formed on both side walls 21d, 21d of the connector housing 21, respectively. . This pair of guides 23,
23, both side walls 21d, 21 of the connector housing 21
On the front side of d, a substantially triangular prism-shaped locking claw (locking portion) 24 that is locked to each of the engaging projections 17 of the opposite side portions 14b, 14b of the connector mounting concave portion 14 is integrally formed. .

Each male terminal 22 is formed in a rod shape by a conductive member, and a substantially U-shaped bent portion 22c is formed between both ends 22a and 22b by bending. Each male terminal 22
The lower side of the other end 22b is the bottom wall 2 of the connector housing 21.
1e by insert molding, and the other end 2
The upper side of 2b projects into the fitting opening 21f of the connector housing 21. One end 22a of each male terminal 22 protrudes outward from the connector housing 21. After the one end 22a is fitted into each groove 15 of the connector mounting recess 14 of the printed circuit board 13, the one end 22a turns around the respective groove 15. The pattern 16 is connected and fixed to the pattern 16 by soldering (this portion is indicated by reference numeral H in FIG. 2). further,
The other end 22b of each male terminal 22 protruding into the fitting opening 21f of the connector housing 21 is connected to each female terminal (terminal) 31 of the male mating connector 30 to which the wire harness W is connected.

According to the mounting structure of the connector 20 of the above embodiment, when the connector housing 21 is mounted in the connector mounting recess 14 of the printed circuit board 13, each pair of guides 2 on both side walls 21 d of the connector housing 21.
3 and 23 are slidably engaged with opposite side portions 14b and 14b of the connector mounting concave portion 14, respectively. As a result, the connector housing 21 is smoothly accommodated in the connector mounting recess 14 from the lateral direction of the printed circuit board 13.

With the connector housing 21 completely accommodated in the connector mounting recess 14 of the printed circuit board 13, one end 22 a of each male terminal 22 projecting outward from the connector housing 21 is connected to each pattern 1 of the printed circuit board 13.
6 and fixed by soldering. At this time, if the mounting state of the connector housing 21 with respect to the connector mounting concave portion 14 of the printed circuit board 13 is incomplete, the connector housing 2 is positioned outside the outer edge 13 a of the printed circuit board 13.
Since 1 protrudes, the incomplete mounting of the connector housing 21 to the connector mounting recess 14 of the printed circuit board 13 can be easily confirmed visually.

The two side walls 2 of the connector housing 21
Locking claw 2 between each pair of guides 1 and 21d
4 and opposite side portions 14b of the connector mounting recess 14,
The connector housing 21 is securely fixed in the connector mounting recess 14 by the engagement of the engagement projections 14b with the engagement projections 17,
Soldering between one end 22a of each male terminal 22 and the pattern 16 of the printed circuit board 13 is performed easily and reliably. This eliminates the necessity of a separate component dedicated to fixing, reducing the number of components by that amount, reducing the overall weight and cost, and improving workability and reliability. Each of the male terminals 22 fixed and protruding in the connector housing 21.
The female terminal 31 of the mating connector 30 can be connected to the other end 22b of the connector.

As described above, when the connector 20 is completely mounted in the connector mounting recess 14 of the printed circuit board 13, the connector 20 is moved from the outer edge (outer periphery) 13 a of the printed circuit board 13.
The connector 20 fits in the connector mounting recess 14 of the printed circuit board 13 without protruding. Therefore, when the connector 20 is not completely mounted on the printed circuit board 13, the incompletely mounted state can be easily confirmed visually.

Further, even if the incomplete mounting of the connector 20 is overlooked visually, it is impossible to assemble the meter 10 in a later process, so that the incomplete mounting of the connector 20 can be reliably prevented. That is, as shown in FIG. 3, the printed circuit board 13 on which the pair of connectors 20 and 20 are mounted is housed in the concave portion 11a on the back side of the meter case 11, but when the connector 20 is incompletely mounted. Since the connector 20 protrudes from the outer edge 13 a of the printed circuit board 13, the printed circuit board 13 is
1a. In addition, as shown in FIG. 4, the printed circuit board 13 is closed and covered by the rear cover 12. However, when the connector 20 is incompletely mounted, the rear cover 12 is attached to the meter case 11.
And cannot be locked.

According to the above-described embodiment, the one end 22a of the male terminal 22 is straightened and the one end 22a is connected and fixed to the pattern 16 around the groove 15 of the printed circuit board 13 by soldering. As shown, the male terminals 22
Of the one end 22a 'is bent into a substantially L-shape.
a 'may be connected and fixed to the wide pattern 16' around the groove 15 of the printed circuit board 13 by soldering to further strengthen the fixed state.

As described above, according to the first aspect of the present invention, the circuit of the board and one end of the terminal protruding outward from the connector housing in a state where the connector housing is housed in the connector mounting recess of the board. Since the connector housing is fixed by soldering, the mounting of the connector housing in the connector mounting recess of the board can be ensured, and the incomplete mounting of the connector housing on the board can be easily confirmed visually.

According to the second aspect of the present invention, the pair of guides on both side walls of the connector housing make the opposite sides of the connector mounting recess of the board slidably engageable. When housing the connector housing, the connector housing can be smoothly housed and mounted in the connector mounting recess.

According to the third aspect of the present invention, the engaging portions and the engaging portions provided between the pair of guides on both side walls of the connector housing and on both opposite side portions of the connector mounting concave portion can be freely locked. As a result, the connector housing can be securely fixed in the connector mounting recess, and soldering between one end of the terminal and the circuit on the board can be performed easily and reliably. This eliminates the need for separate fixing-only parts,
As a result, the number of parts can be reduced, the overall weight and cost can be reduced, and workability and reliability can be improved.
