Description

  The present invention relates to a wiring unit in which a conductive member as electric wiring is resin-molded.

  Conventionally, a wiring unit obtained by resin molding a conductive member is well known. For example, an electronic control unit of an automatic transmission and other electric devices (for example, a hydraulic sensor or an electromagnetic solenoid mounted in the automatic transmission). Valve).

  By the way, in the manufacture of a conventional wiring unit, a method of dividing resin molding into two stages of primary molding and secondary molding is adopted. When a plurality of conducting members are separated and stacked, in primary molding, a primary insert molded product is provided by inserting a conducting member into a mold and resin molding, and in secondary molding, a plurality of primary moldings are provided. The insert molded product is inserted into a mold and resin molded to obtain a final product as a secondary insert molded product (see, for example, Patent Document 1).

However, according to this conventional manufacturing method, the following drawbacks have been pointed out due to the fact that primary molding is insert molding.
First of all, in both the primary and secondary molding, it is necessary to arrange the inserts in the mold as prescribed, so the work is complicated.
Secondly, in both the primary and secondary molds, the die-cutting direction must be taken into account for the terminal portion of the conductive member (hereinafter referred to as the terminal), which increases the mold cost. .

  Thirdly, in the primary molding, when insert molding is performed in a state where a plurality of conductive members are separated and laminated, in order to ensure the fluidity of the resin between the conductive members in the mold, the interval between the conductive members is a predetermined limit. It is necessary to set more than the thickness. For this reason, the final product becomes thick in the stacking direction of the conductive members.

Furthermore, according to the conventional manufacturing method, the following drawbacks have been pointed out due to the resin molding by inserting the primary insert molded product in the secondary molding.
In other words, when the terminal is provided so as to protrude from the primary insert molding product and resin is molded around the protruding terminal in the secondary molding, the terminals are deformed by the flow pressure of the resin and the terminals come into contact with each other, causing a short circuit. There is a risk of doing.

  Therefore, the wiring unit is required to have a structure capable of obtaining a final product without providing a primary insert molded product.

[Effects of Examples]
The wiring unit 1 of the embodiment is provided by performing secondary molding by inserting a primary laminated body 24 in which a primary assembly 22B is laminated on the upper side of the primary assembly 22A into a mold. Here, protrusions 26a to 26h extending downward are provided on the lower surface of the base 21b constituting the primary assembly 22B, and the protrusions 26a to 26h are provided in the primary laminated body 24. The upward lifting of the conductive members 2a and 2b constituting 22A is restricted.

  As a result, the floating of the conductive members 2a and 2b is regulated by the protrusions 26a to 26h in the secondary molding die, and the conductive members 2a and 2b are prevented from coming into contact with the conductive members 2c and 2d and short-circuiting. be able to. Therefore, the primary assembly 22A in which the conductive members 2a to 2d are held on the pedestal 21a is secondarily molded without inserting only the conductive members 2a to 2d into the mold and providing a primary insert molded product. Thus, the wiring unit 1 can be obtained.

  In the primary assembly 22A, the conductive members 2a to 2d are fitted in the upper and lower layers in the fitting groove 23, and the notches 27 are provided in the upper conductive members 2c and 2d. The protrusions 26a to 26c pass through the notch 27 provided in the conductive member 2c and contact the lower conductive member 2b, and the protrusions 26d to 26h pass through the notch 27 provided in the conductive member 2d. Then, it contacts the lower conductive member 2a.

  Thereby, the floating of the conductive members 2a and 2b on the lower layer side can be restricted by the protrusions 26a to 26h. For this reason, the conductive member 2a, 2b on the lower layer side is lifted by the fluid pressure of the resin for secondary molding in the mold during the secondary molding, and is prevented from contacting and short-circuiting with the conductive member 2c, 2d on the upper layer side. be able to.

  Furthermore, the conduction members 2a and 2b have a widened portion 28 that extends in the horizontal direction. Then, the protrusions 26a to 26c abut on the widened portion 28 provided on the conductive member 2b to restrict the floating of the conductive member 2b, and the protrusions 26d to 26h contact the widened portion 28 provided on the conductive member 2a. The contact member regulates the floating of the conductive member 2a.

  Thus, even if the notch 27 is not so large, the protrusions 26a to 26h are thinned, so that the protrusions 26a to 26h are allowed to pass through the upper conductive members 2c and 2d so that the protrusions 26a to 26h are connected to the lower conductive member. 2a and 2b can be brought into contact with each other. For this reason, the floating of the lower conductive members 2a and 2b can be restricted by the contact of the protrusions 26a to 26h with the widened portion 28 while securing the current capacity of the upper conductive members 2c and 2d.

For example, if there is no problem in the current capacity of the conducting members 2c and 2d, the conducting members 2c and 2d can be cut off without providing the widened portion 28. The notch 27 may be provided large, and the protrusion 26 may be brought into direct contact with the conducting members 2a and 2b to restrict the floating of the conducting members 2a and 2b.
