And the second side surfaces 434a and 43b are punched out and cut to the other side, so that the waste materials 80 do not stay in the hollow portion 75, and as shown in FIG. work when the connecting plate portion 74 _{2-74 3} of the connecting plate portion 73 _{2-73 4} or the conductive plate material 72 was set to punching by one side for discharging the waste material 80 which remains in the cavity 75 in a small space Although it becomes necessary, the troublesome waste material discharging work can be omitted, so that the number of processing steps can be further reduced.

Between the lower mold 83 and the upper mold 84, the conductor plate assembly 40 and the conductor plates 45 to 5 of the conductor plate assembly 40 are provided.
When the electric component connection assembly unit 41 is manufactured by forming the mold portion 34 by press-filling the cavity 65 with a synthetic resin in a state where the coil assemblies 27 connected to the Terminal support 4 in assembly 40
4, the molding pressure will act from its surroundings,
The terminal support 44 must withstand the molding pressure. For this reason, if the terminal support portion 44 is formed as a solid thick flat plate so as to withstand the molding pressure, the molding compression of the synthetic resin at each portion of the terminal support portion 44 due to the thick wall is performed. With the change in the ratio, the arrangement of the connector terminals 45b to 53b provided at one end of each of the conductor plates 45 to 53 penetrating the terminal support portion 44 changes, and the connector terminals 45b to 53b after the completion of molding. Placement accuracy may be reduced. On the other hand, the terminal supporting portion 44 has
Thin supporting portions 62, 63, 64 for supporting 53
And four sets of lightening recesses 67 each of which is lightened while leaving the guide portion 60 and the thin connecting wall portions 65 and 66.
, 68 ..., 69 ..., 70 ... are provided to prevent the placement accuracy of the connector terminals 45b to 53b from being lowered due to a change in the molding compression ratio of the synthetic resin due to the thickness. be able to. Moreover, each lightening recess 67

With the conductor plate assembly 40 housed between the lower mold 83 and the upper mold 84, a gate provided on the upper mold 84 is provided above the conductor plate array 43 on the support base 42. 86, 86 are opposed to each other, and a downward bending load acts on the conductor plate arrangement portion 43 by the injection pressure of the synthetic resin from the gates 86, 86. If the conductor plate arrangement portion 43 is deformed by the bending load, a part of the individual conductor plate 46 or 50 is exposed from the mold portion 34, and it becomes difficult to maintain insulation. However, the conductor plate arrangement part 4
3 includes a pair of long leg pins 90, 9 that contact the lower mold 83.
0 and a plurality of, for example, three short leg pins 91 contacting the lower mold 83 are provided at intervals in the longitudinal direction of the conductor plate array portion 43, and the bending load due to a necessary and sufficient injection pressure is provided. The conductor plate array portion 43 can be given strength enough to withstand the above-mentioned conditions, and occurrence of insulation failure due to a portion of the individual conductor plate 46 or 50 being exposed from the mold portion 34 can be reliably prevented.

Further, the long leg pins 90, 90 are
Of the conductive plate assembly 40
The positioning recesses 92 are fitted with the long leg pins 90 to regulate the width direction position of the conductor plate arrangement portion 43, but along the longitudinal direction of the conductor plate arrangement portion 43. Are formed in a long hole shape that allows the long leg pins 90 to move in the directions.
The position of the support base 42 in the longitudinal direction in the lower mold 83
, 98, 99, 100,... Are fitted to the terminal support 44 at one end in the longitudinal direction of the support base 42 and are regulated. Therefore, it is not necessary to strictly determine the position of the long leg pins 90 provided on the rod-shaped conductor plate arrangement portion 43 along the longitudinal direction of the conductor plate arrangement portion 43.
The dimensional accuracy of the mold used for forming the conductor plate array portion 43, that is, the conductor plate assembly 40, can be set relatively coarsely.

Further, the first side surface 43a of the conductor plate arrangement portion 43
The one side end of the individual conductor plate 46 disposed on the second side and the one side end of the individual conductor plate 50 disposed on the second side surface 43b of the conductor plate arrangement portion 43 are connected to each other when forming the conductor plate assembly 40. Since it has a function of positioning and supporting by contacting the mold, the conductor plate
3 and is flush with the fourth side surface 43d of the conductor plate array portion 4 of the individual conductor plates 46 and 50 when the electric component connection assembly unit 41 is formed between the two dies 83 and 84 as it is.
There is a possibility that the supporting strength to the support plate 3 becomes relatively weak and the conductor plates 46 and 50 are peeled or deformed. However, the first and second side surfaces 43a, 43b protrude from the fourth side surface 43d.
The retaining portions 94a, 94b which engage with one end of the individual conductor plates 46, 50 at both ends of the pair of raised portions 93, 93 extending therebetween.
Are formed, and the individual conductor plates 46 and 50 are formed.
The retaining plate portions 96a and 96b which are respectively engaged with the notches 95a and 95b provided at one side end and are flush with the first and second side surfaces 43a and 43b are provided in the conductor plate array portion 43. . Therefore, the supporting strength of the individual conductor plates 46 and 50 to the conductor plate arrangement portion 43 is relatively increased, and the conductor plates 46 and 50 are relatively strong.
It is possible to prevent peeling and deformation of the 50 as much as possible.
