Description

本発明は、樹脂体、及び、電気接続箱に関する。 The present invention relates to a resin body and an electrical connection box.

従来から、車両に搭載され、ヒューズ、リレー、及び電子制御ユニット等の種々の電子部品を収容空間の内部に収容する電気接続箱が提案されている。例えば、従来の電気接続箱の一つは、収容空間を有する筐体と、筐体の内部空間に設けられるとともに電子部品等と導通接続されるスタッドボルトと、スタッドボルトの設置箇所にて筐体に取り付けられるサイドカバーと、を備えている（例えば、特許文献１を参照）。 Electrical junction boxes have been proposed that are mounted on vehicles and house various electronic components such as fuses, relays, and electronic control units inside the housing space. For example, one conventional electrical junction box includes a housing having a housing space, stud bolts that are provided in the internal space of the housing and electrically connected to the electronic components, and a side cover that is attached to the housing at the location where the stud bolts are provided (see, for example, Patent Document 1).

特開２０１３－７４６５５号公報JP 2013-74655 A

ところで、上述したサイドカバーは、電気接続箱の筐体に組み付けられる前に、電線及びＬ字状の端子を有する端子付き電線が組み付けられている。このため、端子のがたつきを抑制すべく、サイドカバーには端子を係止する係止部が設けられている。一方、端子のがたつきを抑制するため、係止部と端子とが密着するように構成されることが好ましいが、端子がＬ字状であるため、サイドカバーへの端子付き電線の組み付け作業の観点から、係止部と端子との間には、クリアランスが設けられている。このため、端子のがたつきを十分に抑制できないおそれがあり、これにより、スタッドボルトへの端子の位置決めが困難になるおそれがある。また、端子のがたつきを十分に抑制できないと、端子付き電線における電線を所望の方向へと引き出そうと電線を引っ張ることで、端子にがたつきが生じるおそれがあり、電線を所望の方向に引き出すことが困難になる。 The side cover described above is assembled with an electric wire and an electric wire with an L-shaped terminal before being assembled to the housing of the electrical connection box. For this reason, the side cover is provided with a locking portion for locking the terminal in order to suppress rattling of the terminal. On the other hand, in order to suppress rattling of the terminal, it is preferable that the locking portion and the terminal are configured to be in close contact with each other, but since the terminal is L-shaped, a clearance is provided between the locking portion and the terminal from the viewpoint of the assembly work of the electric wire with terminal to the side cover. For this reason, rattling of the terminal may not be sufficiently suppressed, which may make it difficult to position the terminal on the stud bolt. Furthermore, if rattling of the terminal cannot be sufficiently suppressed, pulling the electric wire in the electric wire with terminal in order to pull it in the desired direction may cause rattling of the terminal, making it difficult to pull the electric wire in the desired direction.

本発明は、上述した状況を鑑みてなされたものであり、その目的は、端子付き電線における端子のがたつき抑制に優れる樹脂体、及び、電気接続箱を提供することにある。 The present invention was made in consideration of the above-mentioned circumstances, and its purpose is to provide a resin body and an electrical connection box that are excellent at suppressing rattling of terminals in terminal-attached electric wires.

前述した目的を達成するために、本発明に係る樹脂体は、下記を特徴としている。 To achieve the above-mentioned objectives, the resin body according to the present invention has the following characteristics:

Similarly, the mounting portion and the first restricting portion clamp the mating connection portion in the first direction, thereby restricting displacement of the terminal in the first direction. Similarly, the mounting portion and the second restricting portion clamp the mating connection portion in the third direction, thereby restricting displacement of the terminal in the third direction. In this way, the resin body of this configuration restricts displacement of the terminal in all directions, thereby suppressing rattling of the terminal.

＜実施形態＞
以下、図面を参照しながら、図１等に示す本発明の実施形態に係るサイドカバー４０について説明する。サイドカバー４０は、電気接続箱１の側壁部１１に組み付けられる樹脂成形体である。電気接続箱１は、典型的には、車両に搭載され、リレー等の電子部品やその他の部品である電子部品Ｒ（図２～図３参照）を収容する内部空間を有するリレーボックスである。 <Embodiment>
Hereinafter, with reference to the drawings, a side cover 40 according to an embodiment of the present invention shown in Fig. 1 etc. will be described. The side cover 40 is a resin molded body that is attached to the side wall portion 11 of the electrical junction box 1. The electrical junction box 1 is typically a relay box that is mounted on a vehicle and has an internal space for accommodating electronic components such as relays and other electronic components R (see Figs. 2 and 3).

以下、説明の便宜上、図１～図１０に示すように、「前」、「後」、「左」、「右」、「上」及び「下」を定義する。「前後方向」、「左右方向」及び「上下方向」は、互いに直交している。電気接続箱１の車両搭載時において、「前後方向」、「左右方向」及び「上下方向」は、それぞれ、車両の前後方向、左右方向及び上下方向に対応している。また、上下方向は、本発明の「第１方向」に対応している。更に、左右方向は、本発明の「第２方向」に対応している。更に、前後方向は、本発明の「第３方向」に対応している。 For ease of explanation, the following definitions are used for "front," "rear," "left," "right," "upper," and "lower" as shown in Figs. 1 to 10. The "front-rear direction," "left-right direction," and "upper-lower direction" are mutually perpendicular. When the electrical junction box 1 is mounted on a vehicle, the "front-rear direction," "left-right direction," and "upper-lower direction" correspond to the front-rear direction, left-right direction, and upper-lower direction of the vehicle, respectively. The upper-lower direction corresponds to the "first direction" of the present invention. Furthermore, the left-right direction corresponds to the "second direction" of the present invention. Furthermore, the front-rear direction corresponds to the "third direction" of the present invention.

図１に示すように、電気接続箱１は、フレーム１０と、フレーム１０の下端開口を塞ぐようにフレーム１０の下方に組み付けられるロアカバー２０と、フレーム１０の上端開口を塞ぐようにフレーム１０の上方に組み付けられるアッパカバー３０と、フレーム１０の側壁部１１に組み付けられるサイドカバー４０（本発明の「樹脂体」に対応）と、により構成される。電気接続箱１を構成する上記４つの部品は全て、樹脂成形体である。 As shown in FIG. 1, the electrical junction box 1 is composed of a frame 10, a lower cover 20 attached to the bottom of the frame 10 so as to close the bottom opening of the frame 10, an upper cover 30 attached to the top of the frame 10 so as to close the top opening of the frame 10, and a side cover 40 (corresponding to the "resin body" of the present invention) attached to the side wall portion 11 of the frame 10. All four of the above components that make up the electrical junction box 1 are resin molded bodies.

電気接続箱１では、図１に示すように、電気接続箱１の内部に位置する電子部品Ｒの一部に導通接続される電線（図示省略）が、電気接続箱１の後方左部に設けられた電線引出孔（図示省略）を介して、電気接続箱１の外部へと導出される。更に、他の電子部品Ｒの一部に導通接続される電線（図示省略）は、電気接続箱１の前方右部に設けられた電線引出孔（図示省略）を介して電気接続箱１の外部に導出される。 As shown in FIG. 1, in the electrical junction box 1, an electric wire (not shown) that is electrically connected to a part of an electronic component R located inside the electrical junction box 1 is led out to the outside of the electrical junction box 1 through an electric wire outlet hole (not shown) provided in the rear left part of the electrical junction box 1. Furthermore, an electric wire (not shown) that is electrically connected to a part of another electronic component R is led out to the outside of the electrical junction box 1 through an electric wire outlet hole (not shown) provided in the front right part of the electrical junction box 1.

加えて、サイドカバー４０に保持された端子付き電線５０が、電気接続箱１の内部空間に設けられたスタッドボルトＳに接続・締結されて、サイドカバー４０の収容部４２を通り、電気接続箱１の外部へと導出される。 In addition, the terminal-equipped electric wires 50 held by the side cover 40 are connected and fastened to the stud bolts S provided in the internal space of the electrical connection box 1, and are led out to the outside of the electrical connection box 1 through the housing section 42 of the side cover 40.

端子付き電線５０は、電線５１と、電線５１の端末に接続される端子５２と、により構成される（図２～図３参照）。電線５１は、一端が端子５２と接続され、他端が例えばバッテリやオルタネータ等と接続される。端子５２は、図２～図３、図６、及び図８～図９に示すように、上下方向に延びて電線５１と接続される電線側接続部５３と、前方に延びてスタッドボルトＳに接続・締結される相手側接続部５４と、が一体に構成されて、略Ｌ字状に形成されている。なお、相手側接続部５４には、上下方向に貫通し、スタッドボルトＳが挿通される孔部が設けられている。以下、電気接続箱１を構成するフレーム１０、ロアカバー２０、アッパカバー３０、及びサイドカバー４０について順に説明する。 The terminal-attached electric wire 50 is composed of an electric wire 51 and a terminal 52 connected to the end of the electric wire 51 (see Figs. 2 to 3). One end of the electric wire 51 is connected to the terminal 52, and the other end is connected to, for example, a battery or an alternator. As shown in Figs. 2 to 3, 6, and 8 to 9, the terminal 52 is formed in a substantially L-shape by integrally forming an electric wire-side connection part 53 that extends vertically and is connected to the electric wire 51, and a mating connection part 54 that extends forward and is connected and fastened to a stud bolt S. The mating connection part 54 has a hole that penetrates vertically and through which the stud bolt S is inserted. The frame 10, lower cover 20, upper cover 30, and side cover 40 that constitute the electric connection box 1 will be described below in order.

まず、フレーム１０について説明する。図１に示すように、フレーム１０は、上下方向に延びる略矩形筒状の側壁部１１を備える。側壁部１１は、電気接続箱１の側面の外観の大部分を構成する。 First, the frame 10 will be described.

The side wall portion 11 constitutes most of the exterior of the side of the electrical connection box 1.

側壁部１１の下端部における周方向の複数箇所（本例では、８箇所）の外面には、それぞれ、上下方向に延びる貫通孔を含む被係止部１２が一体に設けられている。被係止部１２は、ロアカバー２０をフレーム１０に組み付ける機能を有する。また、側壁部１１の上端部における周方向の複数箇所（本例では、３箇所）の外面には、それぞれ、被係止部１３が一体に設けられている。被係止部１３は、アッパカバー３０をフレーム１０に組み付ける機能を有する。 The outer surface of the lower end of the side wall portion 11 is integrally provided with a plurality of engaging portions 12 including through holes extending in the vertical direction at multiple locations (eight locations in this example) in the circumferential direction. The engaging portions 12 function to assemble the lower cover 20 to the frame 10. The upper end of the side wall portion 11 is integrally provided with a plurality of engaging portions 13 in the circumferential direction at multiple locations (three locations in this example) in the outer surface. The engaging portions 13 function to assemble the upper cover 30 to the frame 10.

側壁部１１における後方左部の電線引出孔に対応する箇所には、下方に開口する半円筒状の樋状部１４が、左下方向に斜めに延びるように設けられている。樋状部１４は、後方左部の電線引出孔を画成する内壁の上側部分を構成する機能を有する。また、側壁部１１における前方右部の電線引出孔に対応する箇所には、下方に開口する半円筒状の樋状部１５が、右方に延びるように設けられている。樋状部１５は、前方右部の電線引出孔を画成する内壁の上側部分を構成する機能を有する。 A semi-cylindrical gutter 14 that opens downward is provided at a location on the side wall 11 that corresponds to the electric wire outlet hole at the rear left, and extends diagonally downward and to the left. The gutter 14 functions to form the upper part of the inner wall that defines the electric wire outlet hole at the rear left. In addition, a semi-cylindrical gutter 15 that opens downward is provided at a location on the side wall 11 that corresponds to the electric wire outlet hole at the front right, and extends to the right. The gutter 15 functions to form the upper part of the inner wall that defines the electric wire outlet hole at the front right.

側壁部１１の下端部における周方向の複数箇所の外面には、それぞれ、下方に延びるステー部１６が一体に設けられている。ステー部１６は、その先端部を車両の搭載箇所に組み付けることで、フレーム１０（即ち、電気接続箱１）を車両の搭載箇所に固定する機能を有する。 Stay portions 16 extending downward are integrally provided on the outer surface of the lower end of the side wall portion 11 at multiple locations in the circumferential direction. The stay portions 16 have the function of fixing the frame 10 (i.e., the electrical connection box 1) to the mounting location of the vehicle by assembling their tips to the mounting location of the vehicle.

スタッドボルトＳ近傍（本例では、後方）の側壁部１１には、サイドカバー４０が組み付けられる被組付部１７が設けられている。被組付部１７には、例えばサイドカバー４０の係止部（図示省略）が係止される被係止部（図示省略）が設けられる。 The side wall portion 11 near the stud bolt S (in this example, the rear) is provided with an attachment portion 17 to which the side cover 40 is attached. The attachment portion 17 is provided with a locking portion (not shown) to which a locking portion (not shown) of the side cover 40 is locked, for example.

次いで、ロアカバー２０について説明する。図１に示すように、ロアカバー２０は、電気接続箱１の下側側面の外観の大部分を構成する環状の側壁部２１と、側壁部２１の環状の下端開口を塞ぐとともに電気接続箱１の底面の外観の大部分を構成する底壁部２２と、を一体に備える。側壁部２１の環状の上端縁部は、フレーム１０の側壁部１１の環状の下端縁部に対応する形状を有し、側壁部１１の環状の下端縁部と嵌合可能となっている。 Next, the lower cover 20 will be described. As shown in FIG. 1, the lower cover 20 is integrally formed with an annular side wall portion 21 that constitutes most of the appearance of the lower side surface of the electrical junction box 1, and a bottom wall portion 22 that closes the annular lower end opening of the side wall portion 21 and constitutes most of the appearance of the bottom surface of the electrical junction box 1. The annular upper edge portion of the side wall portion 21 has a shape that corresponds to the annular lower edge portion of the side wall portion 11 of the frame 10, and is capable of fitting with the annular lower edge portion of the side wall portion 11.

側壁部２１の上端部における周方向の複数箇所（本例では、８箇所）の外面には、それぞれ、フレーム１０の複数の被係止部１２に対応して、上方に延びる係止片２３が一体に設けられている。 The upper end of the side wall 21 has multiple (eight in this example) circumferentially extending locking pieces 23 formed integrally on the outer surface thereof, each of which corresponds to one of the multiple locking portions 12 of the frame 10.

側壁部２１における後方左部の電線引出孔に対応する箇所には、上方に開口する半円筒状の樋状部２４が、左下方向に斜めに延びるように設けられている。樋状部２４は、後方左部の電線引出孔を画成する内壁の下側部分を構成する機能を有する。また、側壁部２１における前方右部の電線引出孔に対応する箇所には、上方に開口する半円筒状の樋状部２５が、右方に延びるように設けられている。樋状部２４は、前方右部の電線引出孔を画成する内壁の下側部分を構成する機能を有する。 A semi-cylindrical gutter 24 that opens upward is provided at a location on the side wall 21 that corresponds to the electric wire outlet hole at the rear left, and extends diagonally downward and to the left. The gutter 24 functions to form the lower part of the inner wall that defines the electric wire outlet hole at the rear left. In addition, a semi-cylindrical gutter 25 that opens upward is provided at a location on the side wall 21 that corresponds to the electric wire outlet hole at the front right, and extends to the right. The gutter 24 functions to form the lower part of the inner wall that defines the electric wire outlet hole at the front right.

次いで、アッパカバー３０について説明する。図１に示すように、アッパカバー３０は、電気接続箱１の上側側面の外観の大部分を構成する環状の側壁部３１と、側壁部３１の環状の上端開口を塞ぐと共に電気接続箱１の上面の外観の大部分を構成する上壁部３２と、を一体に備える。側壁部３１の環状の下端縁部は、フレーム１０の側壁部１１の環状の上端縁部に対応する形状を有し、側壁部１１の環状の上端縁部と嵌合可能となっている。側壁部３１における周方向の複数箇所（本例では、３箇所）の外面には、それぞれ、フレーム１０の複数の被係止部１３に対応して、係止部３３が一体に設けられている。 Next, the upper cover 30 will be described. As shown in FIG. 1, the upper cover 30 is integrally provided with an annular side wall portion 31 that constitutes most of the appearance of the upper side surface of the electrical connection box 1, and an upper wall portion 32 that closes the annular upper end opening of the side wall portion 31 and constitutes most of the appearance of the upper surface of the electrical connection box 1. The annular lower end edge portion of the side wall portion 31 has a shape that corresponds to the annular upper end edge portion of the side wall portion 11 of the frame 10, and is capable of fitting with the annular upper end edge portion of the side wall portion 11. Locking portions 33 are integrally provided on the outer surface of the side wall portion 31 at multiple locations in the circumferential direction (three locations in this example), corresponding to the multiple locked portions 13 of the frame 10.

次いで、サイドカバー４０について説明する。図２～図５に示すように、サイドカバー４０は、上下方向に延びる第１壁部４１と、左右方向において離間して配置される一対の第２壁部４３と、が一体に構成されている。これにより、サイドカバー４０は、前方及び上下方向に開口する端子付き電線５０の収容部４２が画成されている。 Next, the side cover 40 will be described. As shown in Figs. 2 to 5, the side cover 40 is integrally formed with a first wall portion 41 extending in the vertical direction and a pair of second wall portions 43 spaced apart in the left-right direction. This defines a storage portion 42 for the terminal-attached electric wire 50 that opens forward and in the vertical direction.

本実施形態では、第２壁部４３は、第１壁部４１の左右両端及び左右方向略中央領域にそれぞれ設けられている。これにより、一対の収容部４２が左右方向に隣接して配置されている。なお、左右方向略中央領域の第２壁部４３については、上下方向下側領域が一体に構成されている。 In this embodiment, the second wall portion 43 is provided at both the left and right ends of the first wall portion 41 and in an approximately central region in the left-right direction. This allows a pair of storage portions 42 to be arranged adjacent to each other in the left-right direction. Note that the second wall portion 43 in the approximately central region in the left-right direction has a lower region in the up-down direction that is integrally formed.

つまり、第１壁部４１はいわゆる底壁としての機能を有し、左右方向両端の第２壁部４３はいわゆる側壁としての機能を有し、左右方向略中央領域の第２壁部は、いわゆる隣接する収容部４２の仕切壁としての機能を有する。また、第２壁部４３は、端子付き電線５０の保持状態において、端子５２（特に、相手側接続部５４）の左右方向の変位を規制する機能を有する（図７参照）。 In other words, the first wall 41 functions as a bottom wall, the second wall 43 at both left and right ends functions as side walls, and the second wall in the approximately central region in the left and right direction functions as a partition wall between adjacent storage sections 42. The second wall 43 also functions to restrict left and right displacement of the terminal 52 (particularly the mating connection section 54) when the terminal-attached electric wire 50 is held (see FIG. 7).

なお、第１壁部４１は、上下方向下側領域に位置する第１部分４１ａと、上下方向上側領域に位置する第２部分４１ｂと、第１部分４１ａ及び第２部分４１ｂの間に位置する第３部分と、から構成されている。そして、第１部分４１ａは、第２部分４１ｂよりも後方に位置している。これにより、後述するように、端子５２のがたつきを抑制しつつ、サイドカバー４０への端子付き電線５０の組み付け作業に必要なスペースが確保される。 The first wall 41 is composed of a first portion 41a located in the lower region in the vertical direction, a second portion 41b located in the upper region in the vertical direction, and a third portion located between the first portion 41a and the second portion 41b. The first portion 41a is located rearward of the second portion 41b. This ensures the space required for the assembly of the terminal-attached electric wire 50 to the side cover 40 while suppressing rattling of the terminal 52, as described below.

各第２壁部４３には、それぞれ、端子付き電線５０の相手側接続部５４が載置される載置部４４が、対応する収容部４２の内方に向けて突出するように設けられている（図４～図５参照）。また、各第２壁部４３には、それぞれ、載置部４４よりも上方且つ前方に配置される第１規制部４５が、対応する収容部４２の内方に向けて突出するように設けられている。第１規制部４５は、端子付き電線５０の保持状態において、載置部４４とともに相手側接続部５４を上下方向に挟み込むことで、端子５２（特に、相手側接続部５４）の上下方向の変位を規制する機能を有する（図６参照）。 Each second wall portion 43 is provided with a mounting portion 44 on which the mating connection portion 54 of the terminal-fitted wire 50 is placed, protruding toward the inside of the corresponding storage portion 42 (see Figures 4 and 5). Each second wall portion 43 is also provided with a first restricting portion 45 disposed above and forward of the mounting portion 44, protruding toward the inside of the corresponding storage portion 42. When the terminal-fitted wire 50 is held in a held state, the first restricting portion 45 vertically clamps the mating connection portion 54 together with the mounting portion 44, thereby restricting the vertical displacement of the terminal 52 (particularly the mating connection portion 54) (see Figure 6).

第１壁部４１（具体的には、第３部分４１ｃ）における各収容部４２に対応する箇所には、それぞれ、収容部４２の左右方向に離間して配置される一対の第２規制部４６が、前方に向けて突出するように設けられている（図４参照）。第２規制部４６は、端子付き電線５０の保持状態において、載置部４４とともに相手側接続部５４を前後方向に挟み込むことで、端子５２（特に、相手側接続部５４）の前後方向の変位を規制する機能を有する（図６参照）。 A pair of second restricting portions 46 are provided at locations of the first wall portion 41 (specifically, the third portion 41c) corresponding to each of the accommodating portions 42, spaced apart in the left-right direction of the accommodating portion 42, so as to protrude forward (see FIG. 4). When the terminal-attached electric wire 50 is held in a holding state, the second restricting portions 46, together with the mounting portion 44, clamp the mating connection portion 54 in the front-rear direction, thereby restricting the displacement of the terminal 52 (particularly the mating connection portion 54) in the front-rear direction (see FIG. 6).

以上、電気接続箱１を構成するフレーム１０、ロアカバー２０、アッパカバー３０、及びサイドカバー４０について説明した。フレーム１０、ロアカバー２０、アッパカバー３０、及びサイドカバー４０からなる電気接続箱１を組み付けるためには、フレーム１０にロアカバー２０、アッパカバー３０、及びサイドカバー４０をそれぞれ組み付ける必要がある。 The frame 10, lower cover 20, upper cover 30, and side cover 40 that make up the electrical connection box 1 have been described above. In order to assemble the electrical connection box 1 consisting of the frame 10, lower cover 20, upper cover 30, and side cover 40, it is necessary to assemble the lower cover 20, upper cover 30, and side cover 40 to the frame 10.

まず、フレーム１０にロアカバー２０を組み付ける。フレーム１０にロアカバー２０を組み付けるためには、ロアカバー２０の複数の係止片２３（図１参照）を、下方からフレーム１０の被係止部１２（図１参照）の複数の貫通孔にそれぞれ挿入し、この状態から、ロアカバー２０の側壁部２１の環状の上端縁部をフレーム１０の側壁部１１の環状の下端縁部に嵌合させ、且つ、複数の係止片２３を複数の被係止部１２に係止させる。これにより、フレーム１０へのロアカバー２０の組み付けが完了する。 First, the lower cover 20 is attached to the frame 10. To attach the lower cover 20 to the frame 10, the multiple locking pieces 23 (see FIG. 1) of the lower cover 20 are inserted from below into the multiple through holes of the locked portion 12 (see FIG. 1) of the frame 10, and from this state, the annular upper edge of the side wall portion 21 of the lower cover 20 is fitted into the annular lower edge of the side wall portion 11 of the frame 10, and the multiple locking pieces 23 are locked to the multiple locked portions 12. This completes the attachment of the lower cover 20 to the frame 10.

その後、サイドカバー４０に端子付き電線５０を組み付ける（詳細は後述する）。その後、フレーム１０にサイドカバー４０を組み付ける。フレーム１０にサイドカバー４０を組み付けるためには、端子付き電線５０をスタッドボルトＳに接続・締結させ、且つ、フレーム１０の被組付部１７にサイドカバー４０を組み付ける。 Then, the electric wires with terminals 50 are attached to the side cover 40 (details will be described later). Then, the side cover 40 is attached to the frame 10. To attach the side cover 40 to the frame 10, the electric wires with terminals 50 are connected and fastened to the stud bolts S, and the side cover 40 is attached to the attachment portion 17 of the frame 10.

具体的には、端子付き電線５０における端子５２の孔部５５をスタッドボルトＳに挿通させ、そしてナットＮを締めることで、端子付き電線５０がスタッドボルトＳに接続・締結される。その後、サイドカバー４０の係止部（図示省略）をフレーム１０の被係止部（図示省略）に係止させる。これにより、フレーム１０へのサイドカバー４０の組み付けが完了する。 Specifically, the hole 55 of the terminal 52 in the terminal-attached electric wire 50 is inserted into the stud bolt S, and the nut N is tightened, thereby connecting and fastening the terminal-attached electric wire 50 to the stud bolt S. After that, the locking portion (not shown) of the side cover 40 is locked to the locked portion (not shown) of the frame 10. This completes the assembly of the side cover 40 to the frame 10.

その後、フレーム１０にアッパカバー３０を組み付ける。フレーム１０にアッパカバー３０を組み付けるためには、アッパカバー３０の側壁部３１の環状の下端縁部をフレーム１０の側壁部１１の環状の上端縁部に嵌合させ、且つ、アッパカバー３０の複数の係止部３３をフレーム１０の複数の被係止部１２に係止させる。これにより、フレーム１０へのアッパカバー３０の組み付けが完了する。 Then, the upper cover 30 is assembled to the frame 10. To assemble the upper cover 30 to the frame 10, the annular lower edge of the side wall portion 31 of the upper cover 30 is fitted into the annular upper edge of the side wall portion 11 of the frame 10, and the multiple locking portions 33 of the upper cover 30 are locked to the multiple locked portions 12 of the frame 10. This completes the assembly of the upper cover 30 to the frame 10.

これにより、フレーム１０にロアカバー２０、アッパカバー３０、及びサイドカバー４０がそれぞれ組み付けられて、電気接続箱１が完成される。なお、フレーム１０へのロアカバー２０の組み付け工程と、フレーム１０へのサイドカバー４０の組み付け工程と、の順番の前後は問わない。 As a result, the lower cover 20, upper cover 30, and side cover 40 are respectively assembled to the frame 10, and the electrical connection box 1 is completed. Note that the order of the assembly process of the lower cover 20 to the frame 10 and the assembly process of the side cover 40 to the frame 10 does not matter.

電気接続箱１の組付完了状態では、複数の係止片２３と複数の被係止部１２との係止により、ロアカバー２０がフレーム１０から下方へ分離することが防止される。同様に、複数の係止部３３と複数の被係止部１３との係止により、アッパカバー３０がフレーム１０から上方へ分離することが防止される。なお、サイドカバー４０についても同様に、フレーム１０の被係止部（図示省略）とサイドカバー４０の複数の係止部（図示省略）との係止により、サイドカバー４０がフレーム１０から後方へ分離することが防止される。 When the electrical connection box 1 is in a fully assembled state, the lower cover 20 is prevented from separating downward from the frame 10 by the engagement between the multiple locking pieces 23 and the multiple locked portions 12. Similarly, the upper cover 30 is prevented from separating upward from the frame 10 by the engagement between the multiple locking portions 33 and the multiple locked portions 13. Similarly, the side cover 40 is prevented from separating backward from the frame 10 by the engagement between the locked portions (not shown) of the frame 10 and the multiple locking portions (not shown) of the side cover 40.

更に、フレーム１０の被組付部１７の外面とサイドカバー４０の収容部４２の内面とにより端子付き電線５０が挿通される電線挿通路が画成される（図示省略）。同様に、フレーム１０の樋状部１４と、ロアカバー２０の樋状部２４とにより、電線（図示省略）が挿通される後方左部の電線引出孔が画成される。同様に、フレーム１０の樋状部１５と、ロアカバー２０の樋状部２５とにより、電線（図示省略）が挿通される前方右部の電線引出孔が画成される。 Furthermore, the outer surface of the mounting portion 17 of the frame 10 and the inner surface of the accommodating portion 42 of the side cover 40 define an electric wire insertion passage through which the terminal-attached electric wire 50 is inserted (not shown). Similarly, the gutter-shaped portion 14 of the frame 10 and the gutter-shaped portion 24 of the lower cover 20 define an electric wire outlet hole at the rear left through which the electric wire (not shown) is inserted. Similarly, the gutter-shaped portion 15 of the frame 10 and the gutter-shaped portion 25 of the lower cover 20 define an electric wire outlet hole at the front right through which the electric wire (not shown) is inserted.

次いで、サイドカバー４０への端子付き電線５０の組み付け方法について図８～図９を参照して説明する。まず、端子付き電線５０の上端部を後方に倒すように傾けて、相手側接続部５４を、載置部４４と第２規制部４６との間の隙間に挿入する（図８参照）。 Next, a method for assembling the terminal-attached electric wire 50 to the side cover 40 will be described with reference to Figures 8 and 9. First, the upper end of the terminal-attached electric wire 50 is tilted backward, and the mating connection part 54 is inserted into the gap between the mounting part 44 and the second restricting part 46 (see Figure 8).

相手側接続部５４を所定位置まで挿入後、相手側接続部５４と載置部４４とが上下方向に対向（換言すると略平行）となるように後方に倒した端子付き電線５０の上端部を元の位置に戻し、相手側接続部５４と載置部４４とが相対的に近付くように端子付き電線５０を下方へと移動させる（図９の矢印参照）。相手側接続部５４は、下方への移動途中において上方から下方に向けて第１規制部４５を乗り越え、そして、所定位置に到達する。これにより、端子付き電線５０がサイドカバー４０に組み付けられる。換言すると、端子付き電線５０は、サイドカバー４０に保持される（図２及び図６～図７参照）。 After the mating connection part 54 is inserted to a predetermined position, the upper end of the terminal-attached wire 50, which has been tilted backward so that the mating connection part 54 and the mounting part 44 are vertically opposed (in other words, approximately parallel), is returned to its original position, and the terminal-attached wire 50 is moved downward so that the mating connection part 54 and the mounting part 44 become relatively closer to each other (see the arrow in Figure 9). On its way downward, the mating connection part 54 climbs over the first restricting part 45 from above to below, and then reaches a predetermined position. This causes the terminal-attached wire 50 to be assembled to the side cover 40. In other words, the terminal-attached wire 50 is held by the side cover 40 (see Figures 2 and 6-7).

端子付き電線５０は、保持状態において、相手側接続部５４が、一対の第２壁部４３に左右方向に挟み込まれて、端子５２の左右方向の変位が規制される（図７参照）。同様に、端子付き電線５０は、保持状態において、相手側接続部５４が、載置部４４及び第１規に上下方向に挟み込まれて、端子５２の上下方向の変位が規制される（図６参照）。同様に、端子付き電線５０は、保持状態において、相手側接続部５４が、載置部４４及び第２規制部４６に前後方向に挟み込まれて、端子５２の前後方向の変位が規制される（図６参照）。 In the held state, the electric wire with terminal 50 has the mating connection portion 54 sandwiched between the pair of second wall portions 43 in the left-right direction, restricting the left-right displacement of the terminal 52 (see FIG. 7). Similarly, in the held state, the electric wire with terminal 50 has the mating connection portion 54 sandwiched between the placement portion 44 and the first restriction portion 46 in the up-down direction, restricting the up-down displacement of the terminal 52 (see FIG. 6). Similarly, in the held state, the mating connection portion 54 has the mating connection portion 54 sandwiched between the placement portion 44 and the second restriction portion 46 in the front-rear direction, restricting the front-rear displacement of the terminal 52 (see FIG. 6).

また、サイドカバー４０は、前後方向に延びる相手側接続部５４に対して、載置部４４と第１規制部４５とが前後方向に異なる位置に設けられることで、端子５２のがたつき（特に、相手側接続部５４の前端の浮き上がり）をより適正に抑制できる。 In addition, the side cover 40 has the placement portion 44 and the first restriction portion 45 located at different positions in the front-rear direction relative to the mating connection portion 54 that extends in the front-rear direction, so that rattling of the terminal 52 (particularly lifting of the front end of the mating connection portion 54) can be more appropriately suppressed.

このように、サイドカバー４０は、端子５２のあらゆる方向への変位を規制することで、端子５２のがたつきを抑制できる。これにより、端子付き電線５０における端子５２の孔部５５の位置決め精度が向上し、例えば、フレーム１０へのサイドカバー４０の組み付け時において、端子付き電線５０をスタッドボルトＳに容易に接続・締結できる。また、電線５１の引っ張りによる端子５２のがたつきが抑制されるため、電線５１を所望の方向へと引き出すことができる。 In this way, the side cover 40 can restrict the displacement of the terminal 52 in all directions, thereby suppressing rattling of the terminal 52. This improves the positioning accuracy of the hole 55 of the terminal 52 in the terminal-attached electric wire 50, and for example, when assembling the side cover 40 to the frame 10, the terminal-attached electric wire 50 can be easily connected and fastened to the stud bolt S. In addition, rattling of the terminal 52 due to pulling on the electric wire 51 is suppressed, so the electric wire 51 can be pulled out in the desired direction.

なお、サイドカバー４０への端子付き電線５０の組み付け作業は、いわゆるワンアクションで行うことができ、組み付け作業性に優れる。 The assembly of the terminal-attached electric wire 50 to the side cover 40 can be performed in a single action, making the assembly process easy.

また、第１壁部４１の第２部分４１ｂに何も設けられていないことで、載置部４４と第２規制部４６との間の隙間に端子付き電線５０を挿入する際、第２部分４１ｂに突起等が設けられている場合に比べて、端子付き電線５０の上端部を後方に倒さなくてもよいため、第１部分４１ａと第２部分４１ｂとの前後方向の距離を近付けることができる。つまり、本実施形態に係るサイドカバー４０においては、小型化を図ることができる。 In addition, since there is nothing provided on the second portion 41b of the first wall portion 41, when inserting the terminal-attached electric wire 50 into the gap between the mounting portion 44 and the second restricting portion 46, it is not necessary to tilt the upper end of the terminal-attached electric wire 50 backward, compared to when a protrusion or the like is provided on the second portion 41b, and therefore the distance in the front-to-rear direction between the first portion 41a and the second portion 41b can be shortened. In other words, the side cover 40 according to this embodiment can be made smaller.

＜他の形態＞
なお、本発明は、上述した実施形態に限定されるものではなく、適宜、変形、改良、等が可能である。その他、上述した実施形態における各構成要素の材質、形状、寸法、数、配置箇所、等は本発明を達成できるものであれば任意であり、限定されない。 <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.

図１０に示すように、第１規制部４５における相手側接続部５４と対向する面（本例では、下端面）を、突出先端から突出基端に向かうにつれて相手側接続部５４に近付く傾斜状に形成してもよい。一般に、係止部と係止部に係止される被係止部材との間には、クリアランスを設ける必要がある。このため、被係止部材は、クリアランスの大きさだけがたつくおそれがある。しかしながら、上記構成により、第１規制部４５と相手側接続部５４との間に必要なクリアランスを設けつつも、第１規制部４５の突出基端においては、クリアランスを小さくできるため、端子５２のがたつきをより適正に抑制できる。 As shown in FIG. 10, the surface of the first restricting portion 45 facing the mating connection portion 54 (in this example, the lower end surface) may be formed in an inclined shape that approaches the mating connection portion 54 from the protruding tip toward the protruding base end. In general, a clearance must be provided between the locking portion and the locked member that is locked to the locking portion. For this reason, the locked member may wobble only due to the size of the clearance. However, with the above configuration, while providing the necessary clearance between the first restricting portion 45 and the mating connection portion 54, the clearance can be made small at the protruding base end of the first restricting portion 45, so that wobbling of the terminal 52 can be more appropriately suppressed.

電気接続箱（１）。 Here, the features of the embodiments of the resin body and the electrical junction box according to the present invention described above will be briefly summarized and listed in the following [1] to [3].
[1]
A resin body (side cover 40) configured to be capable of holding a terminal-attached electric wire (50) having an L-shaped terminal (52) consisting of an electric wire-side connection portion (53) and a mating connection portion (54), and to be assembled to a housing (frame 10, lower cover 20, upper cover 30) that houses an electronic component (R),
A first wall portion (41) extending in a first direction;
a pair of second walls (43) that are spaced apart from each other in a second direction intersecting the first direction and that are capable of restricting displacement of the terminal (52) in the second direction,
Each of the pair of second walls (43) has
a mounting portion (44) on which the mating connection portion (54) can be mounted;

Resin body (side cover 40).
[2]
In the resin body (side cover 40) described in [1] above,
The placement portion (44) and the first restriction portion (45) are
The mating connection portion (54) is provided at different positions in the third direction, which is the extension direction of the mating connection portion (54).
Resin body (side cover 40).
[3]
An electrical connection box (1) including the resin body (side cover 40) according to the above-mentioned [1] or [2], an electric wire with terminal (50), and a housing (frame 10, lower cover 20, upper cover 30) that houses an electronic component (R),

Electrical junction box (1).

上記［１］の構成の樹脂体によれば、一対の第２壁部が、相手側接続部を第２方向に挟み込むことで、端子の第２方向の変位を規制する。同様に、載置部及び第１規制部が、相手側接続部を第１方向に挟み込むことで、端子の第１方向の変位を規制する。同様に、載置部及び第２規制部が、相手側接続部を第３方向に挟み込むことで、端子の第３方向の変位を規制する。このように、本構成の樹脂体は、端子のあらゆる方向への変位を規制するため、端子のがたつきを抑制できる。 According to the resin body of the configuration [1] above, the pair of second walls sandwich the mating connection part in the second direction, thereby restricting the displacement of the terminal in the second direction. Similarly, the placement part and the first restriction part sandwich the mating connection part in the first direction, thereby restricting the displacement of the terminal in the first direction. Similarly, the placement part and the second restriction part sandwich the mating connection part in the third direction, thereby restricting the displacement of the terminal in the third direction. In this way, the resin body of this configuration restricts the displacement of the terminal in all directions, thereby suppressing rattling of the terminal.

上記［２］の構成の樹脂体によれば、第３方向に延びる相手側接続部に対して、載置部と第１規制部とが第３方向に異なる位置に設けられることで、端子のがたつきをより適正に抑制できる。 According to the resin body having the configuration of [2] above, the placement portion and the first restricting portion are provided at different positions in the third direction relative to the mating connection portion extending in the third direction, so that rattling of the terminal can be more appropriately suppressed.

上記［３］の構成の電気接続箱によれば、一対の第２壁部が、相手側接続部を第２方向に挟み込むことで、端子の第２方向の変位を規制する。同様に、載置部及び第１規制部が、相手側接続部を第１方向に挟み込むことで、端子の第１方向の変位を規制する。同様に、載置部及び第２規制部が、相手側接続部を第３方向に挟み込むことで、端子の第３方向の変位を規制する。このように、本構成の樹脂体は、端子のあらゆる方向への変位を規制するため、端子のがたつきを抑制できる。 According to the electrical connection box of the configuration [3] above, the pair of second walls clamp the mating connection part in the second direction, thereby restricting the displacement of the terminal in the second direction. Similarly, the placement part and the first restricting part clamp the mating connection part in the first direction, thereby restricting the displacement of the terminal in the first direction. Similarly, the placement part and the second restricting part clamp the mating connection part in the third direction, thereby restricting the displacement of the terminal in the third direction. In this way, the resin body of this configuration restricts the displacement of the terminal in all directions, thereby suppressing rattling of the terminal.
