Description

[Technical field]

[0001] The present invention relates to a temporary terminal fixing structure. [Background technology]

[0002] Conventionally, there have been proposed terminal connection structures in which a terminal with an electric wire for power supply, etc. is fastened to a bolt embedded in a resin molded body (e.g., an electrical junction box) so that the terminal with the electric wire is electrically connected to a mating connection member via the bolt (see, for example, Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2010-28919 A [Patent Document 2] JP 2019-87483 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the conventional terminal fixing structure, when the bolt is inserted into the insertion hole of the terminal and before the terminal is fastened by a nut or the like, that is, during the fastening work, an external force is applied (transmitted) to the terminal, which can cause the terminal to come off the resin molded body. More specifically, for example, when an electric wire connected to the terminal is pulled, tension is applied to the terminal, which can cause the terminal to fall off the bolt. As a result, there is a risk that the work will become complicated and parts will be lost.

[0005] The present invention has been made in consideration of the above-mentioned situation, and its purpose is to provide a temporary terminal fixing structure that can prevent a terminal from falling off from a resin molded body even before the terminal with a bolt inserted therethrough is finally fastened by a nut or the like. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the terminal temporary fixing structure according to the present invention has the following features. A terminal temporary fixing structure including a terminal to be connected to a mating terminal and a resin molded body having a terminal accommodating portion in which the terminal is accommodated, The terminal is a connection portion through which a bolt embedded in the terminal accommodating portion is inserted; an extension portion extending from the connection portion in a direction intersecting with an axial direction of the bolt, The resin molded body is a restricting rib disposed on the axial tip side of the extending portion and restricting displacement of the connecting portion toward the axial tip side; The terminal has a temporary fixing structure. Effect of the Invention

[0007] According to the present invention, by arranging the restricting rib provided on the resin molded body closer to the axial tip side than the extension part of the terminal, even if the connection part is displaced toward the axial tip side, that is, the terminal is displaced so as to fall off the bolt, the restricting rib interferes with the extension part, so that the displacement of the connection part toward the axial tip side is restricted. In other words, with the above configuration, the terminal is temporarily fixed to the resin molded body. As a result, according to the present invention, even before the terminal with the bolt inserted therethrough is fully fastened by a nut or the like, it is possible to prevent the terminal from falling off the resin molded body.

[0008] The present invention has been briefly described above. Furthermore, the details of the present invention will be further clarified by reading the following description of the embodiment of the present invention (hereinafter, referred to as "embodiment") with reference to the accompanying drawings. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] <Embodiment> Hereinafter, a terminal temporary fixing structure 1 according to one embodiment of the present invention will be described with reference to the drawings. Note that the "resin molded body" of the present invention is not particularly limited and may be, for example, a housing or a protector, but in the following embodiment, a protector 20 will be described as an example.

[0011] For ease of explanation, "front", "rear", "left", "right", "upper" and "lower" are defined below as shown in FIG. 1 etc. The "front-rear direction", "left-right direction" and "up-down direction" are mutually perpendicular. The "axial direction" of the present invention corresponds to the up-down direction, the "axial tip side" refers to the upper side, and the "axial base end side" refers to the lower side. The "intersecting direction" of the present invention is a direction intersecting the front-rear direction and the left-right direction in a plane perpendicular to the up-down direction.

[0012] 1 and 2, the temporary terminal fixing structure 1 includes a terminal 10 and a protector 20. The temporary terminal fixing structure 1 prevents the terminal 10 from falling off the protector 20 before the terminal 10 is fully fastened (in this example, fastened together with a mating terminal) by, for example, a nut or the like, by temporarily fixing the terminal 10 to the protector 20. The terminal 10 and the protector 20 constituting the temporary terminal fixing structure 1 will be described below in order.

[0013] First, the terminal 10 will be described. As shown in Fig. 3, the terminal 10 is integrally formed with a connecting portion 11 having a substantially rectangular flat plate shape and a crimping portion 12 extending rearward from a rear end portion of the connecting portion 11. The connecting portion 11 functions as a connecting portion with a mating terminal, and the crimping portion 12 functions to connect to and hold an electric wire 30 (see also Figs. 1 and 2).

[0014] A through hole 13 that penetrates in the vertical direction is formed in the approximate center of the connection part 11. A bolt B embedded in a protector 20 (described later) is inserted into the through hole 13 (see Figs. 1, 2 and 7).

[0015] An extension 14 extending toward the front left side is provided at the front left corner of the connection portion 11. An erect portion 15 extending upward is provided at the extending end of the extension 14. The extension 14 and the erect portion 15 have the function of temporarily fixing the terminal 10 to the protector 20.

[0016] Next, the protector 20 will be described. As shown in Figures 3 and 4, the protector 20 has a main body 21 composed of a bottom wall 21a formed in a substantially V-shape when viewed in the up-down direction, and a pair of side walls 21b erected from both ends in the width direction of the bottom wall 21a. The main body 21 is integrally composed of a terminal accommodating portion 22 extending in the front-rear direction, and a mating terminal accommodating portion 23 extending from the front end of the terminal accommodating portion 22 toward the front right side.

[0017] A stay portion 24 is provided integrally with the side wall 21b of the main body portion 21 on the side of an inner corner 25a. The stay portion 24 has a function of assembling the protector 20 to a mounting location of a mounting target member.

[0018] A bolt embedding portion 26 in which a bolt B is embedded is integrally provided in a substantially central portion of the bottom wall 21a of the main body 21 (i.e., a connecting portion between the terminal accommodating portion 22 and the mating terminal accommodating portion 23). The upper surface of the bolt embedding portion 26 is located above the upper surface of the bottom wall 21a.

[0019] A restricting rib 27 extending from the front right side to the rear left side is disposed apart from the bottom wall 21a on the front left side of the bolt-embedded portion 26 of the main body 21. The restricting rib 27 has a function of temporarily fixing the terminal 10 to the protector 20.

[0020] At an outer corner 25b of the main body 21, a space 28 is defined by a restricting rib 27. In the space 28, the standing portion 15 of the terminal 10 is disposed.

[0021] The above describes the terminal 10 and the protector 20 that constitute the temporary terminal fixing structure 1. To obtain the temporary terminal fixing structure 1, it is necessary to accommodate the terminal 10 in the terminal accommodating portion 22 of the protector 20. Hereinafter, a method for accommodating the terminal 10 in the terminal accommodating portion 22 of the protector 20 will be described.

[0022] First, the terminal 10 is placed at a position corresponding to the terminal accommodating portion 22 of the protector 20, and the connection portion 11 of the terminal 10 is tilted with respect to a plane perpendicular to the up-down direction (see FIG. 5). In this state, the erected portion 15 of the terminal 10 is moved from between the bottom wall 21a of the protector 20 and the restricting rib 27 to the space 28 of the protector 20 (see FIG. 6). Finally, the bolt B is inserted through the through hole 13 of the terminal 10 to return the connection portion 11 from the tilted state to its original state substantially parallel to the plane (see FIGS. 1 and 2). This completes the accommodation of the terminal 10 in the terminal accommodating portion 22 of the protector 20. The method of accommodating the terminal 10 in the terminal accommodating portion 22 of the protector 20 has been described above.

[0023] When the terminal 10 is completely accommodated in the terminal accommodating portion 22 of the protector 20, the restricting rib 27 is disposed above the extending portion 14 of the terminal 10 and is disposed in the intersecting direction between the connecting portion 11 and the standing portion 15 disposed in the space 28 (see Figs. 1 and 2). Moreover, when the terminal 10 is completely accommodated in the terminal accommodating portion 22 of the protector 20, the upper end 15a of the standing portion 15 is located above the lower end 27a of the restricting rib 27 (see Fig. 7).

[0024] That is, according to this embodiment, the restricting rib 27 of the protector 20 is disposed above the extending portion 14 of the terminal 10, so that even if the connecting portion 11 is displaced upward, that is, the terminal 10 is displaced so as to fall off the bolt B, the restricting rib 27 interferes with the extending portion 14, thereby restricting the upward displacement of the connecting portion 11. In other words, the terminal 10 is temporarily fixed to the protector 20 by the above configuration. As a result, according to this embodiment, even when the bolt B is inserted through the terminal 10 and before the terminal 10 is fastened by a nut or the like, it is possible to prevent the terminal 10 from falling off the protector 20.

[0025] Furthermore, according to this embodiment, the restricting rib 27 is positioned between the connection portion 11 and the standing portion 15 in the intersecting direction, so that even if the terminal 10 is displaced so as to fall off the bolt B, the restricting rib 27 also interferes with the standing portion 15, thereby properly restricting the upward displacement of the connection portion 11.

[0026] Furthermore, according to this embodiment, the upper end 15a of the standing portion 15 is located higher than the lower end 27a of the restricting rib 27, so that even if the terminal 10 is displaced so as to fall off the bolt B, the restricting rib 27 and the standing portion 15 engage with each other, so that the upward displacement of the connection portion 11 is more appropriately restricted.

[0027] Furthermore, according to this embodiment, the terminal 10 is temporarily fixed to the protector 20 by the extending portion 14 and the erected portion 15 of the terminal 10 and the restricting rib 27 of the protector 20, so there is no need to fix the electric wire 30 connected to the terminal 10 to the protector 20 using a tie band or the like as in the conventional method. As a result, this embodiment is easier to work with than the conventional method.

[0028] <Other forms> The present invention is not limited to the above-described embodiment, and can be appropriately modified, improved, etc. In addition, the material, shape, size, number, arrangement location, etc. of each component in the above-described embodiment are arbitrary as long as the present invention can be achieved, and are not limited.

[0029] Here, the features of the embodiments of the temporary terminal fixing structure according to the present invention described above will be briefly summarized and listed in the following [1] to [3].

[0031] According to the above-mentioned configuration [1], the restricting rib provided on the resin molded body is disposed on the axial tip side of the extension portion of the terminal, so that even if the connection portion is displaced toward the axial tip side, i.e., the terminal is displaced so as to fall off the bolt, the restricting rib interferes with the extension portion, so that the displacement of the connection portion toward the axial tip side is restricted. In other words, the above-mentioned configuration temporarily fixes the terminal to the resin molded body. As a result, with the above-described configuration, even when the bolt is inserted into the terminal and before the terminal is fastened by a nut or the like, it is possible to prevent the terminal from falling off from the resin molded body.

[0032] [2] The terminal temporary fixing structure (1) described in the above [1], The terminal (10) further has a standing portion (15) standing on a tip side in the axial direction from the extension portion (14), The restriction rib (27) is Located between the connection portion (11) and the standing portion (15) in the intersecting direction. Terminal temporary fixing structure (1).

[0033] According to the above configuration [2], the regulating rib is positioned between the connection portion and the standing portion in the intersecting direction, so that even if the terminal is displaced so as to fall off the bolt, the regulating rib also interferes with the standing portion, and thus the displacement of the connection portion toward the axial tip is properly restricted.

[0034] [3] The terminal temporary fixing structure (1) according to the above [2], The axial tip end (upper end 15a) of the standing portion (15) is The restricting rib (27) is located on the axial tip side (upper side) of the axial base end (lower end 27a) of the restricting rib (27). Terminal temporary fixing structure (1).

[0035] According to the above configuration [3], the axial tip end of the erected portion is located axially closer to the tip side than the axial base end of the regulating rib. Therefore, even if the terminal is displaced so as to fall off the bolt, the regulating rib and the erected portion engage with each other, and therefore, displacement of the connection portion toward the axial tip side is more appropriately regulated.
