Structure for assembling bus bar block

Abstract

In order to readily and securely mount, for example, a fuse block to a cover and readily accommodate increase in the number of circuits, bus bars each having on one side a terminal portion for connection of an electrical component and on the other side a terminal portion for connection of circuit board are provided in an insulating block body parallel to each other to constitute a busbar block. The bus bars are prevented from uplifting by virtue of a rib integral with the block body. Recessed portions for positioning are provided in an insulating cover corresponding to the ribs, and at the same time as the busbar block is attached to the cover, the ribs are brought into engagement with the recessed portions to provide positioning of the busbar block. Terminal block constructed by terminals each having on one end thereof a terminal portion for connection of an electrical component and on the other side thereof a terminal portion for connection of circuit board 14b, and an insulating block body holding the terminals. The terminal block is provided between a higher-tier portion of the busbar block and the circuit board.

Description

Technical field [0001] The invention relates to an assembly structure of a bus bar block for positioning and assembling a bus bar block on a cover of a terminal block. Background technique [0002] Figure 8 It shows the main part of one mode of the conventional junction block (refer to Patent Document 1). [0003] This junction block includes: a circuit board 73 on which various electronic components 72 are mounted, a connector block 75 connected by terminals 74 on the left and right sides of the circuit board 73, and a fuse block connected by terminals 76 on the front side of the circuit board 73 77. The circuit board assembly 71 composed of these circuit boards 73 or the blocks 75 and 77 is covered and protected by upper and lower covers (not shown) in a state where the openings 75a and 77a sides of the blocks 75 and 77 are exposed. [0004] The connector block 75 is composed of a connector housing made of insulating resin (substituting the reference numeral 75), and a substantia...

Problems solved by technology

[0008] However, in the above-mentioned conventional junction block, as the number of power supply circuits etc. increases depending on the vehicle grade, it is necessary to change the form in which the number of layers of the fuse block 77 is different, and there is a problem that the cost increases.

[0009] In addition, especially as the fuse block 77 becomes multilayered, there is a possibility that the assembly workability of the circuit board assembly 71 (especially the fuse block portion) to the cover (not shown) may be reduced.

In addition, when inserting a fuse (particularly when inserting a plurality of fuses at the same time into a plurality of fuse connection terminals of one terminal), a strong pushing force is applied to the terminal in the insertion direction, and there is a possibility that the circuit board 73 may be soldered.
