JP 2008-178240 A

  In recent years, with the advancement of electronics in automobiles, the number of electrical components has increased, and the number of wires such as wire harnesses has increased. Naturally, the number of wire harnesses connected to the electrical junction box is also increasing, and the number of terminals to which fuses are connected is also increasing in proportion thereto.

  However, on the upper surface of a conventional electrical junction box, the increase in the number of connector connection portions to which the connector of the wire harness is connected has reduced the room for providing a terminal to which a fuse is connected. Therefore, in order to secure a sufficient connector connection portion and fuse terminals, the area of the upper surface of the electrical connection box must be increased, which contributes to an increase in the size of the electrical connection box.

  The present invention has been made in view of such a situation, and an object thereof is to provide a technology of a connection terminal for a fuse capable of realizing a compact electric connection box.

  In order to solve the above-described problems, a connection terminal according to an aspect of the present invention is a connection terminal to which an upstream wiring and a downstream wiring are attached to an electrical junction box through which a fuse is connected, and the fuse is connected. A connection part to which one terminal of the fuse is connected, a mounting part to be attached to the surface of the wiring board of the electrical connection box from above, and a connection direction of the fuse to the connection part with respect to a mounting direction of the mounting part A bent portion connecting the connecting portion and the attaching portion so as to intersect with each other. The bent portion is folded back from the base portion of the connection portion to the attachment portion side, and is bent toward the attachment portion side at a position closer to the tip of the connection portion than the folded portion.

  According to this aspect, when the fuse is connected to the connection portion with the connection terminal attached to the wiring board, the force applied to the connection portion is applied from the side to the attachment portion. By deforming the bent portion, the force applied to the mounting portion is alleviated.

  Another aspect of the present invention is a connection terminal module. The connection terminal module includes a plurality of connection terminals described above and an insulating fixing member that fixes the plurality of connection terminals in a parallel state so that the connection directions of the fuses are aligned.

  According to this aspect, it becomes easy to attach a plurality of connection terminals to the wiring board in a lump, and workability when manufacturing the electrical connection box is improved. Also, when the fuse is connected to the connection part with the connection terminal module attached to the wiring board, the force applied to the connection part is applied from the side to the attachment part. By deforming the part, the force applied to the attachment part is relaxed. When a fuse is connected to a connection part, the force applied to the connection part is distributed not only to the connection terminal attachment part to which the fuse is connected, but also to other connection terminal attachment parts via a fixing member. Therefore, it is suppressed that an excessive force is applied to one mounting portion.

  Another aspect of the present invention is a connection terminal module. This connection terminal module is a connection terminal module in which the upstream wiring and the downstream wiring are attached to an electrical connection box through which a fuse is connected, and a plurality of connection terminals to which the fuse is connected are fixed by a fixing member. The terminal has a connection part to which one terminal of the fuse is connected, a mounting part that is attached to the surface of the wiring board of the electrical connection box from above, and the connection direction of the fuse to the connection part is the mounting direction of the mounting part. And a bent portion connecting the connecting portion and the mounting portion so as to cross each other. The fixing member fixes the plurality of connection terminals in parallel so that the connection directions of the fuses are aligned.

  According to this aspect, it becomes easy to attach a plurality of connection terminals to the wiring board in a lump, and workability when manufacturing the electrical connection box is improved. In addition, when a fuse is connected to a connection portion with the connection terminal module attached to the wiring board, the force applied to the connection portion is not limited to the attachment portion of the connection terminal to which the fuse is connected, but also the fixing member. Therefore, an excessive force is suppressed from being applied to one mounting portion.

  The fixing member may have a slit formed at a predetermined position on the side surface in the longitudinal direction, and the connection terminal may be press-fitted into the slit. Thereby, it is possible to easily fix the connection terminal.

  The fixing member has a concave portion formed at a predetermined position on the side surface in the longitudinal direction, and the connection terminal has a convex portion protruding from the surface including the connecting portion, and the convex portion is press-fitted into the concave portion. Also good. As a result, the connection terminals can be easily positioned and fixed.

  The fixing member has a convex portion formed at a predetermined position on the side surface in the longitudinal direction, and the connection terminal has a concave portion formed on the surface including the connecting portion, and the convex portion may be press-fitted into the concave portion. . As a result, the connection terminals can be easily positioned and fixed.

  The schematic shape of the connection terminal may be L-shaped, for example. Here, the L-shape does not have to be an L-shape in a strict sense, and may be a shape that is bent so that the connection portion and the attachment portion intersect. In addition, unevenness, bending, or drawing may be partially formed in the middle of the connection portion or the attachment portion.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and repeated descriptions are omitted as appropriate.

(First embodiment)
First, an outline of an electrical connection box that can suitably employ the connection terminal and the connection terminal module according to the present embodiment will be described. FIG. 1 is a diagram schematically showing a power supply system of an automobile electrical junction box. A junction box (electrical connection box) used in an automobile or the like is designed based on a power supply system diagram as schematically shown in FIG. The power supply system of the electrical junction box 10 can be divided into a fuse upstream wiring 14 and a fuse downstream wiring 16 with the fuse 12 as a boundary.

  FIG. 2 is a perspective view of the electrical junction box according to the present embodiment as viewed from above. FIG. 3 is a perspective view showing an example of a wiring board accommodated in the electrical junction box. As shown in FIG. 2, the electrical junction box 10 includes a housing 18 that accommodates a plurality of wiring boards as will be described later. The housing 18 has a rectangular parallelepiped shape in which a plurality of components are assembled, and a plurality of connector connecting portions 20 are provided on the upper surface thereof. Examples of the material constituting the housing 18 include polyamide and polypropylene. The housing 18 can be manufactured by molding the above-described material by an injection molding method or the like.

  The housing 18 is provided with two rows of fuse insertion ports 22 on one side surface. Each fuse insertion port 22 is formed with a rectangular opening so that a plurality of fuses 24 can be mounted in parallel. The fuse 24 includes a fuse body 26 and first and second terminals 28 and 30 extending therefrom. When the first terminal 28 and the second terminal 30 of the fuse 24 are inserted into the housing 18 from the fuse insertion port 22, the first terminal 28 is connected to the connection terminal 32 (see FIG. 4) that is electrically connected to the upstream wiring. Then, the second terminal 30 is connected to the connection terminal 34 (see FIG. 4) that conducts with the downstream wiring.

  FIG. 4 is a perspective view showing a fuse connection structure according to the present embodiment. As shown in FIG. 4, the first terminal 28 and the second terminal 30 of the fuse 24 are pressed in the direction of the arrow, so that the fork-like upstream connection terminal 32 and the fork-like downstream connection terminal 34 are also provided. It will be interrupted toward the root of the bifurcated branch at the tip. As a result, the upstream wiring and the downstream wiring are conducted through the fuse 24.

  The electrical junction box 10 accommodates therein a plurality of wiring boards 36 as shown in FIG. As the wiring board 36, for example, an RPC (Rigid Printed Circuit) board is used. In the following, the uppermost wiring board will be described, and the others will be omitted. In the wiring board 36, connection pins 38 that are connected to external connectors in the connector connection portion 20 are provided at positions corresponding to the connector connection portion 20. Further, one of the four sides of the wiring board 36 is soldered from the back surface in a state where a plurality of upstream connection terminals 32 are arranged in parallel. Note that printed wiring is laid out on the back surface of the wiring board 36 so that some of the connection pins 38 and the corresponding connection terminals 32 are electrically connected.

  Since the above-mentioned electrical connection box 10 has the connector connecting portion 20 on the top surface and the fuse insertion port 22 on the side surface, compared to the case where both the connector connection portion and the fuse insertion port 22 are provided on the top surface. The area of the upper surface can be reduced, and the size is reduced. On the other hand, since the fuse insertion port 22 is provided on the side surface, the connection terminal to which the fuse is connected is L-shaped as represented by the upstream connection terminal 32 attached to the wiring board 36. Yes. In particular, when a plurality of wiring boards 36 are stacked, the upstream connection terminal 32 and the downstream connection terminal 34 must be separated according to the distance between the first terminal 28 and the second terminal 30 of the fuse 24, An L-shaped connection terminal is preferred.

  However, when the L-shaped connection terminal 32 is attached to the surface of the wiring board 36 with solder, when the fuse 24 is pushed in the direction of arrow A shown in FIG. A force in the lateral direction (a direction intersecting the mounting direction of the connection terminal 32) is applied to the mounting portion of the terminal 32 to the wiring board 36. In particular, when the fuses 24 are collectively inserted into a plurality of connection terminals 32 arranged in a row as shown in FIG. 3, the force applied to the connection terminals 32 can be greater.

  Therefore, the present inventor decided to deal with this problem by devising the shape of the connection terminal. FIG. 5A is a perspective view of the connection terminal according to the first embodiment. FIG. 5B is a side view of the connection terminal shown in FIG. Here, the connection terminal 40 shown in FIG. 5 corresponds to the connection terminal 32 shown in FIG.

  The connection terminal 40 is a component obtained by deforming a plate-shaped metal member punched into a predetermined shape into a substantially L shape by bending with a die press. The connection terminal 40 includes a connection portion 42 to which one of the first terminals 28 of the fuse 24 is connected, a mounting portion 44 attached from above to the surface of the wiring board 36 included in the electrical connection box 10, and a connection portion 42. And a bent portion 46 connecting the connecting portion 42 and the mounting portion 44 so that the connecting direction B of the fuse 24 to the crossing with the mounting direction C of the mounting portion 44 is provided.

  The bent portion 46 is folded back from the base portion 42a of the connection portion 42 to the attachment portion 44 side, and is bent again to the attachment portion 44 side at a position closer to the tip end portion 42b of the connection portion 42 than the folded portion. . Here, the width of the base portion 42a is narrower than that of the tip end portion 42b, so that the base portion 42a is easily bent and bent.

  In the connection terminal 40, when the fuse 24 is connected to the connection part 42 in a state where the connection terminal 40 is attached to the wiring board 36, the force applied to the connection part 42 is applied to the attachment part 44 from the side. However, the bending portion 46 is mainly deformed by the force, so that the force applied from the side to the mounting portion 44 is reduced. Therefore, for example, even when the attachment portion 44 is soldered to the wiring board 36, the possibility of cracking in the solder due to the force applied to the solder when the fuse is inserted is reduced, and the connection in the electrical connection box 10 is reduced. Reliability is improved.

  Further, since the connection terminal 40 has a substantially flat upper surface extending from the connection part 42 to the bent part 46, the height when attached to the wiring board 36 can be reduced. For this reason, in particular, by using such connection terminals 40 in the electrical connection box 10 in which a plurality of wiring boards 36 are stacked and accommodated, a compact electrical connection box 10 can be realized while being able to connect many connectors. .

(Second Embodiment)
FIG. 6A is a perspective view of a connection terminal according to the second embodiment. FIG. 6B is a side view of the connection terminal shown in FIG. Here, the connection terminal 140 shown in FIG. 6 corresponds to the connection terminal 32 shown in FIG. Connection terminal 140 in this embodiment has substantially the same configuration except that the shape of the bent portion is different from the shape of bent portion 46 in the first embodiment. Therefore, the same elements as those of the connection terminal 40 according to the first embodiment are denoted by the same reference numerals, and the description thereof is omitted as appropriate.

  The connection terminal 140 is a component obtained by deforming a plate-shaped metal member punched into a predetermined shape into a substantially L shape by bending with a die press. The connection terminal 140 includes a connection portion 42 to which one of the first terminals 28 of the fuse 24 is connected, a mounting portion 44 attached from above to the surface of the wiring board 36 included in the electrical connection box 10, and a connection portion 42. The connecting portion 42 and the mounting portion 44 are connected to each other so that the connecting direction B of the fuse 24 to the crossing with the mounting direction C of the mounting portion 44 has a bent portion 146.

  The bent portion 46 is bent at a substantially right angle from the base portion 42a of the connecting portion 42 to the mounting portion 44 side (first bent portion 146a), and is connected again with the flat surface 146b having a predetermined length sandwiched from the first bent portion 146a. The portion 42 is bent at a substantially right angle (second bent portion 146c). Here, the bent portion 146 is folded back from the base portion 42a of the connecting portion 42 to the mounting portion 44 side by the shape constituted by the first bent portion 146a, the flat surface 146b, and the second bent portion 146c. The bent portion 146 is bent at a substantially right angle toward the mounting portion 44 at a position closer to the distal end portion 42b of the connecting portion 42 than the second bent portion 146c across a flat surface 146d having a predetermined length.

  Therefore, when the fuse 24 is connected to the connection portion 42 in a state where the connection terminal 40 is attached to the wiring board 36, the force applied to the connection portion 42 is applied to the attachment portion 44 from the side. However, the bending portion 146 is mainly deformed by the force, so that the force applied from the side to the mounting portion 44 is reduced. Therefore, for example, even when the attachment portion 44 is soldered to the wiring board 36, the possibility of cracking in the solder due to the force applied to the solder when the fuse is inserted is reduced, and the connection in the electrical connection box 10 is reduced. Reliability is improved.

  In addition, since the connection terminal 40 is configured by a substantially flat surface from the connection part 42 to the bent part 146, the height when attached to the wiring board 36 can be reduced. For this reason, in particular, by using such connection terminals 140 in an electrical connection box that stores and accommodates a plurality of wiring boards, a compact electrical connection box can be realized while being able to connect many connectors.

(Third embodiment)
In the present embodiment, a connection terminal module in which a plurality of the connection terminals 40 and the connection terminals 140 are bundled will be described. FIG. 7 is a perspective view of a connection terminal module according to the third embodiment.

By using this connection terminal module 100, it becomes easy to attach the plurality of connection terminals 40 to the wiring board 36 at once, and the workability when manufacturing the electrical connection box 10 is improved.

  The fixing member 50 is made of an insulating material, and slits 52 are formed as many as the number of connection terminals 40 fixed in parallel in the longitudinal direction of the side surface. The connection terminal 40 is press-fitted into the slit 52 and fixed. With such a configuration, the connection terminal 40 can be easily fixed. The fixing member 50 is attached to the wiring board by an attachment mechanism (not shown) such as a screw or a locking portion. Thereby, when the fuse 24 is connected to the connection portion 42 in a state where the connection terminal module 100 is attached to the wiring board 36, the force applied to the connection portion 42 is applied to the attachment portion from the side. The bending portion 46 is mainly deformed by the force, so that the force applied to the attachment portion 44 is relieved. Further, when the fuse 24 is connected to the connection portion 42, the force applied to the connection portion 42 is not limited to the connection portion 40 to which the fuse 24 is connected, but also to the other connection through the fixing member 50. Since it is also distributed and added to the mounting portion 44 of the terminal 40, it is possible to prevent an excessive force from being applied to one mounting portion 44. Needless to say, the same effect as described above can be obtained even if the connection terminal 140 according to the second embodiment is used instead of the connection terminal 40.

  In the case of such a connection terminal module, the shape of the bent portion of the connection terminal to be fixed does not necessarily have to be folded back like the connection terminal 40 or the connection terminal 140. FIG. 8 is a perspective view showing another example of a connection terminal suitable for the connection terminal module according to the third embodiment. Connection terminal 240 in this embodiment has substantially the same configuration except that the shape of the bent portion is different from the shape of bent portion 46 in the first embodiment. Therefore, the same elements as those of the connection terminal 40 according to the first embodiment are denoted by the same reference numerals, and the description thereof is omitted as appropriate.

  The connection terminal 240 is a component obtained by deforming a plate-shaped metal member punched into a predetermined shape into an L shape by bending with a die press. The connection terminal 240 includes a connection portion 42 to which one of the first terminals 28 of the fuse 24 is connected, a mounting portion 44 attached from above to the surface of the wiring board 36 included in the electrical connection box 10, and a connection portion 42. And a bent portion 246 connecting the connecting portion 42 and the attaching portion 44 so that the connecting direction B of the fuse 24 to the mounting portion C intersects the attaching direction C of the attaching portion 44. The connection terminal 240 according to the present embodiment is bent at the bent portion 246 so that the connection portion 42 and the attachment portion 44 are substantially orthogonal to each other. The above-described effects can be obtained by a connection terminal module in which a plurality of such connection terminals 240 are fixed.

(Fourth embodiment)

The connection terminal module 200 includes a plurality of connection terminals 240 shown in FIG. 8 and a rod-shaped fixing member 150 that fixes the plurality of connection terminals 240 in parallel so that the connection directions of the fuses are aligned. The fixing member 150 has a concave groove 152 formed in the longitudinal direction in a region corresponding to the upper surface of FIG. 9 among the four side surfaces in the longitudinal direction. On the other hand, the connection terminal 240 has a convex portion (not shown) protruding downward from the surface including the connection portion 42, and the convex portion is press-fitted into the concave groove 152. As a result, the connection terminal 240 can be easily positioned and fixed.

  As another embodiment of the connection terminal module, a convex portion is formed at a predetermined position on the side surface in the longitudinal direction of the fixing member, a concave portion is formed on a surface including the connection portion of the connection terminal, and the concave portion of the connection member is formed. The convex part of the fixing member may be press-fitted into. As a result, the connection terminals can be easily positioned and fixed. In addition, the connection terminal used in the connection terminal module according to the present embodiment may be the connection terminal 40 or the connection terminal 140 instead of the connection terminal 240.
