Problems solved by technology

[0012] However, in Figure 2A , Figure 2B In the configuration shown, the corner wall 63 formed between the pair of side walls 61 and the connection wall 62 of the case 60 is curved so that the corner of the nut comes into contact with the corner wall 63 of the case 60 . , the corner of the nut interferes with the curved surface of the corner wall 63 of the casing 60, and the nut cannot be arranged at a specified position in the casing 60.
[0013] Therefore, in order to accommodate the nuts in the housing 60, the housing 60 must be made larger, resulting in an increase in the size of the housing 60.

Embodiment Construction

[0035] Hereinafter, embodiments of the present invention will be described in detail using the drawings.

[0036] refer to Figure 3-7B , the nut press-fit holding structure 1 of the terminal block 10 according to the embodiment of the present invention will be described.

[0037] like Figure 3-5 As shown, the terminal block 10 using the nut press-fit holding structure 1 includes: a plurality of shells 2 protruding from one side of the terminal block 10; a gasket 3 for waterproof and dustproof; a nut 4 fixed to the shell 2; The thermistor connector 5 formed to protrude from the housing 2; the bolt 6 engaged with the nut 4; the external wire terminal 7 connected to the bus bar 11 described later by the nut 4 and the bolt 6; and the terminal block 10 formed as Integrated plate 9 and bus bar 11 .

[0038] A plurality of bus bars 11 are formed to protrude from the terminal block 10 . The bus bar 11 has a bolt insertion hole 19 through which the bolt 6 is inserted.

Abstract

PROBLEM TO BE SOLVED: To provide a nut press-fitting holding structure capable of preventing concentration of stress to a fastening torque without enlarging a housing into which a nut is press-fitted.SOLUTION: There is provided a nut press-fitting holding structure 1 of the terminal board 10 including: a housing 2; and a nut 4 which is press-fitted into a nut press-fitting part 21 of the housing 2. The nut press-fitting part 21 is provided with curvilinear stress releasing parts 33 so as to prevent corner parts 39 of the nut 4 from contacting therewith.

Description

technical field [0001] The present invention relates to a terminal fixing structure, in particular to a nut press-fit holding structure for press-fitting a nut into a terminal block of a housing. Background technique [0002] As shown in Patent Document 1, when a conductor is attached to a terminal block, an external terminal connection hole for connecting an external terminal is provided on the conductor. [0003] On the conductor mounting surface of the conductor, a terminal mounting recess is provided at a position corresponding to the external line terminal connection hole opened on each mounted conductor. [0004] Nuts having approximately the same shape as the terminal mounting recesses are fitted into the terminal mounting recesses, and the conductors are connected to the external wire terminals by screwing the nuts and bolts together. [0005] In addition, in Figure 1A , Figure 1B In the case 50 of the terminal block as shown, a nut 52 is press-fitted into a nut ...
