no. 1 Embodiment approach

[0032] refer to Figure 1 to Figure 10 , the insulating cover 100 of the first embodiment will be described. First, an example of the electrical connection structure 10 using the insulating cover 100 will be described. This electrical connection structure 10 is also the same in, for example, the second to sixth embodiments described later. However, the insulating cover 100 of each embodiment is not limited to the examples shown below, and can be widely applied to various electrical connection structures.

[0033] figure 1 It is a partially exploded perspective view showing an example of the electrical connection structure 10 . The electrical connection structure 10 includes, for example, a plurality of electric wires 200 , a plurality of crimp terminals 300 , a terminal block 400 and a plurality of fixing members 500 . In addition, in this specification, the crimp terminal 300 and the electric wire 200 which are mutually connected are collectively called "electric wire uni...

no. 2 Embodiment approach

[0096] Next, a second embodiment will be described. The second embodiment differs from the first embodiment in that the insulating cover 100 has a cover 140 . In addition, the configuration other than the configuration described below is the same as that of the first embodiment.

[0097] Figure 11 It is a perspective view which shows the insulation cover 100 of 2nd Embodiment. In the present embodiment, the first support portion 130A has a first constricted portion 131A bent in a direction approaching the second support portion 130B. For example, the first constricted portion 131A is provided over the entire length of the second cover portion 112 in the Z direction. The first constricted portion 131A includes a first portion 131Aa bent from the end of the second cover portion 112 on the +X direction side in a direction approaching the second support portion 130B, and a first portion 131Aa bent from the +X direction side of the first portion 131Aa. The second part 131Ab is...

no. 3 Embodiment approach

[0107] Next, a third embodiment will be described. The third embodiment differs from the first embodiment in that the insulating cover 100 can be attached to the electric wire unit U from multiple directions. In addition, the configuration other than the configuration described below is the same as that of the first embodiment.

[0108] Figure 13 It is a perspective view which shows the electric wire unit U and the insulating cover 100. In the present embodiment, as the installation direction of the insulating cover 100 with respect to the electric wire unit U, the same installation direction as that of the first embodiment is referred to as the "first installation direction", and the second installation direction relative to the above-mentioned first installation direction is referred to as "first installation direction". When the direction that differs by 90 degrees in the circumferential direction θ2 is referred to as the "second mounting direction", and the direction th...

Abstract

The insulating cover (100) includes a cover body (110) and a pair of support parts (130A, 130B). The cover body (110) is open in one direction in the radial direction of the cylindrical portion (310) of the crimp terminal, and is arranged outside the terminal block, at least not connecting the plate portion (320) of the crimp terminal with the terminal. The area facing the electrical connection part of the stage covers and covers the above-mentioned cylindrical part (310). The pair of support parts (130A, 130B) face at least one of the electric wire and the cylindrical part from the side opposite to the cover main body (110).

Description

technical field [0001] The present invention relates to insulating covers. Background technique [0002] A crimp terminal with an insulating sheath and a cylindrical insulating cap are known as insulating components for securing the insulation of the cylindrical portion of the crimp terminal. [0003] However, crimp terminals with insulating sheaths are classified for each size of crimp terminal threads in addition to the size of the electric wire. Therefore, in the case of using crimp terminals with insulating sheaths, it is necessary to have many kinds of stock. In addition, in both cases of crimp terminals with insulating sheaths and insulating caps, retrofitting and replacement are often difficult.
