Description

The present invention relates to an electronic component mounting section.

Automobiles are equipped with a wide variety of electronic devices. To supply power and transmit signals to these various electronic devices, electrical junction boxes composed of a collection of electronic components such as connectors, relays, and fuses are installed in appropriate locations between the power source and the electronic devices (Patent Document 1).

The electronic component has an electronic component body and terminals protruding from the electronic component body. The electrical junction box is provided with an electronic component mounting section on which the electronic component is mounted. The electronic component mounting section is formed with cavities (terminal accommodating chambers) that accommodate terminals that connect to the terminals of the electronic component. When the electronic component is mounted on the electronic component mounting section, the terminals of the electronic component are connected to the terminals accommodated in the cavities.

Japanese Patent Application Laid-Open No. 2018-7424

The cavity in conventional electrical junction boxes is located at a cavity position opposite the terminal position of the electronic component. As a result, it is not possible to mount electronic components with terminal positions that do not face the cavity position. If you want to change to a different electronic component with a different terminal position, you have to remake the electrical junction box itself, which is a problem.

The present invention was made in consideration of the above-mentioned circumstances, and its purpose is to provide an electronic component mounting section that does not need to be remade even if it is desired to change to another electronic component with a different terminal arrangement.

In order to achieve the above-mentioned object, the electronic component mounting section according to the present invention is characterized by the following [1] to [ 3 ].

(First embodiment)
A specific first embodiment of the present invention will be described below with reference to the drawings. For ease of explanation, the terms "front-rear direction,""left-rightdirection,""up-downdirection,""front,""rear,""left,""right,""up," and "down" are defined in FIGS. 1 to 4. The "front-rear direction,""left-rightdirection," and "up-down direction" are perpendicular to one another.

As shown in Figures 1 to 3, the relay mounting unit (electronic component mounting unit) 1 of this embodiment can exclusively mount both a first relay 21 (first electronic component) and a second relay 22 (second electronic component), which have different terminal arrangement positions. That is, as shown in Figure 2, when the first relay 21 is mounted on the relay mounting unit 1, the second relay 22 cannot be mounted. Also, as shown in Figure 3, when the second relay 22 is mounted on the relay mounting unit 1, the first relay 21 cannot be mounted on the relay mounting unit 1. This relay mounting unit 1 is housed in an electrical junction box mounted on a vehicle.

First, before describing the relay mounting unit 1, the first relay 21 and the second relay 22 will be described with reference to Figures 4 and 5. As shown in Figure 4, the first relay 21 has a relay body 211 and multiple tab terminals T11 to T14 protruding from the relay body 211. The relay body 211 is formed in a cubic shape. In this embodiment, four tab terminals T11 to T14 protrude from a terminal protruding surface S1, which is one surface of the relay body 211. The terminal protruding surface S1 is also formed in a substantially square shape. Note that in Figure 4, the direction along one side of the substantially square-shaped terminal protruding surface S1 is defined as the X direction, and the direction perpendicular to the X direction on the terminal protruding surface S1 is defined as the Y direction.

As shown in FIG. 4 , the tab terminals T11 and T12 of the first relay 21 have the same size and shape and are arranged parallel to the Y direction on the terminal protruding surface S1, and are arranged side by side in the X direction. The tab terminals T13 and T14 have the same size and shape and are wider and thicker than the tab terminals T11 and T12. The tab terminal T13 is arranged parallel to the X direction on the terminal protruding surface S1, and is located to one side in the Y direction (upper side in the drawing) of the portion between the tab terminals T11 and T12. The tab terminal T14 is arranged parallel to the Y direction on the terminal protruding surface S1 and is located to the other side in the Y direction (lower side in the drawing) of the portion between the tab terminals T11 and T12.

Next, the configuration of the second relay 22 described above will be explained. As shown in FIG. 5, the second relay 22 has a relay body 221 and multiple tab terminals T21 to T24 protruding from the relay body 221. The relay body 221 is formed in a cubic shape. In this embodiment, four tab terminals T21 to T24 protrude from a terminal protruding surface S2, which is one surface of the relay body 221. The terminal protruding surface S2 is formed in a rectangular shape that is elongated in the Y direction. In FIG. 5, the short side direction of the terminal protruding surface S2 is the X direction, and the long side direction of the terminal protruding surface S1 is the Y direction.

As shown in FIG. 5, the tab terminals T21 to T24 of the second relay 22 are provided with the same size and shape. Furthermore, the tab terminals T21 to T24 are provided with the same size and shape as the tab terminals T11 and T12 of the first relay 21. The tab terminals T21 and T22 are arranged parallel to the Y direction on the terminal protruding surface S2 and are aligned in the X direction. The terminals T23 and T24 are arranged parallel to the X direction on the terminal protruding surface S2 and are aligned in the Y direction. Furthermore, the terminals T23 and T24 are arranged to one side in the Y direction (below in the drawing) of the tab terminals T21 and T22.

Next, we will explain the relay mounting portion 1. In this embodiment, the relay mounting portion 1 is made of synthetic resin or the like. As shown in Figure 1, the relay mounting portion 1 is formed by integrally molding a first mounting portion 11, a second mounting portion 12, and a third mounting portion 13 from resin.

The first mounting portion 11 is a rectangular parallelepiped that is elongated in the front-to-rear direction and is hollow with an open bottom. The first mounting portion 11 is also provided with first terminal accommodating chambers C11 and C12 that can accommodate tab terminals T13 and T14 (first terminals), which are part of the tab terminals T11 to T14 provided on the first relay 21. The first terminal accommodating chamber C11 is provided on the front side of the first mounting portion 11, and the first terminal accommodating chamber C12 is provided on the rear side of the first mounting portion 11. The top surface of the first mounting portion 11 is provided with an opening 111 that is elongated in the left-to-right direction and communicates with the first terminal accommodating chamber C11. The tab terminal T13 can be inserted into the first terminal accommodating chamber C11 through this opening 111.

In addition, an opening 112 that is elongated in the front-to-rear direction and communicates with the first terminal accommodating chamber C12 is provided on the top surface of the first mounting portion 11. The tab terminal T14 can be accommodated in the first terminal accommodating chamber C12 through this opening 112.

The second mounting portion 12 is hollow and has an open bottom. It is provided with second terminal accommodating chambers C21-C23 that can accommodate tab terminals T21, T22, and T23 (second terminals), which are part of the tab terminals T21-T24 provided on the second relay 22. In this embodiment, a pair of second mounting portions 12 are provided. The pair of second mounting portions 12 are arranged side by side in the left-right direction. The first mounting portion 11 is provided between the pair of second mounting portions 12. The second mounting portion 12 has a cubic first portion 121 that is elongated in the front-rear direction, and a cubic second portion 122 that protrudes from the center of the first portion 121 in the front-rear direction toward the first mounting portion 11. The second terminal accommodating chambers C21 and C22 are arranged side by side in the front-rear direction in the first portion 121, and the second terminal accommodating chamber C23 is provided in the second portion 122.

Openings 123 and 124, which are elongated in the left-right direction and communicate with the second terminal accommodating chambers C21 and C22, respectively, are provided on the top surface of the first portion 121, aligned in the front-to-rear direction. Tab terminals T22 and T21 can be inserted into the second terminal accommodating chambers C21 and C22 through these openings 123 and 124. Opening 125, which is elongated in the front-to-rear direction and communicates with the second terminal accommodating chamber C23, is provided on the top surface of the second portion 122. Tab terminal T23 can be inserted into the second terminal accommodating chamber C23 through this opening 125.

The third mounting portion 13 is cubic and hollow with an open bottom. The third mounting portion 13 is provided with a third terminal accommodating chamber C3 that can exclusively accommodate tab terminals T11 and T12 (third terminals), which are the tab terminals T11 to T14 provided on the first relay 21, excluding the tab terminals T13 and T14, and tab terminal T24 (fourth terminal), which is the tab terminals T21 to T24 provided on the second relay 22, excluding the tab terminals T21 to T23.

In this embodiment, a pair of third mounting portions 13 are provided. The pair of third mounting portions 13, 13 are arranged side by side. The left side (one) of the pair of third mounting portions 13, 13 is provided between the left side (one) of the pair of second mounting portions 12, 12 and the first mounting portion 11. The right side (the other) of the pair of third mounting portions 13, 13 is provided between the right side (the other) of the pair of second mounting portions 12, 12 and the first mounting portion 11. An opening 131 that is elongated in the front-to-rear direction and communicates with the third terminal accommodating chamber C3 is provided on the top surface of the third mounting portion 13. A tab terminal T12, T13, or T22 can be inserted into the third terminal accommodating chamber C3 through this opening 131.

The first to third terminal accommodating chambers C11, C12, C21 to C23, and C3 accommodate female terminal fittings (not shown) that mate with the tab terminals T11 to T14 and T21 to T24, respectively. Therefore, when the tab terminals T11 to T14 and T21 to T24 are accommodated in the first to third terminal accommodating chambers C11, C12, C21 to C23, and C3, the tab terminals T11 to T14 and T21 to T24 mate with the female terminal fittings.

Next, an example of how to use the relay mounting section 1 configured as described above will be described. First, a case in which one first relay 21 is mounted on the relay mounting section 1 will be described. In this case, the X direction of the first relay 21 is aligned parallel to the left-right direction, and the first relay 21 is mounted on the relay mounting section 1 with the tab terminal T13 at the front and the tab terminal T14 at the rear. At this time, the tab terminal T13 is accommodated in the first terminal accommodating chamber C11, the tab terminal T14 is accommodated in the first terminal accommodating chamber C12, and the tab terminals T11 and T12 are accommodated in the left and right third terminal accommodating chambers C3. As shown in FIG. 2, when the first relay 21 is mounted, the second mounting section 12 is not used.

Next, we will explain the case where two second relays 22 are mounted on the relay mounting section 1. One of the two second relays 22 is mounted on the second and third mounting sections 12 and 13 on the right side of the first mounting section 11. In this case, the second relay 22 is mounted on the relay mounting section 1 with the X direction of the second relay 22 parallel to the front-to-rear direction, with tab terminals T21 and T22 on the right side and tab terminals T23 and T24 on the left side. The other of the two second relays 22 is mounted on the second and third mounting sections 12 and 13 on the left side of the first mounting section 11. In this case, the second relay 22 is mounted on the relay mounting section 1 with the X direction of the second relay 22 parallel to the front-to-rear direction, with tab terminals T21 and T22 on the left side and tab terminals T23 and T24 on the right side.

At this time, tab terminals T21 and T23 are accommodated in the second terminal accommodating chambers C21 and C22, tab terminal T23 is accommodated in the second terminal accommodating chamber C23, and tab terminal T24 is accommodated in the third terminal accommodating chamber C3. As shown in Figure 3, when the second relay 22 is installed, the first mounting portion 11 is not used.

In the above-described embodiment, the relay mounting portion 1 can exclusively mount both the first relay 21 and the second relay 22, eliminating the need to redesign the relay even when changing from the first relay 21 to the second relay 22 or from the second relay 22 to the first relay 21. Furthermore, by providing the third mounting portion 13 with the third terminal accommodating chamber C3 that can exclusively accommodate both the tab terminals T11 and T12 provided on the first relay 21 and the tab terminal T24 provided on the second relay 22, miniaturization can be achieved.

In the above-described embodiment, by providing a pair of second and third mounting sections, it is possible to change the mounted component from one first relay 21 to two second relays 22.

In the first embodiment described above, two second relays 22 are attached, but this is not limited to this. Only one second relay 22 may be attached. In this case, the second and third mounting portions 12, 13 on either the left or right side are not used.

In addition, in the first embodiment described above, a pair of second mounting sections 12 and third mounting sections 13 are provided, but this is not limited to this. Only one second mounting section 12 and one third mounting section 13 may be provided.

Second Embodiment
Next, a second embodiment will be described with reference to Figures 6 to 10. Note that in Figures 6 to 10, parts equivalent to those of the relay mounting unit 1 shown in Figures 1 to 3 already described in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. The relay mounting unit 1B of this embodiment can exclusively mount both a first relay 21 and a second relay 22, which have different terminal arrangement positions. Furthermore, when mounting the first relay 21, it is also possible to select whether or not to connect the first relay 21 to the bus bar 16. The first relay 21 and second relay 22 have already been described in the first embodiment, so detailed description thereof will be omitted here.

The relay mounting portion 1B is formed integrally from resin with the first mounting portion 11B, second mounting portion 12, third mounting portion 13, and busbar accommodating portion 14.

As shown in FIG. 6, the first mounting portion 11B is a rectangular parallelepiped that is elongated in the front-to-rear direction and is hollow with an open bottom. The first mounting portion 11B also has a fourth terminal accommodating chamber C4, a fifth terminal accommodating chamber C5, and a sixth terminal accommodating chamber C6 that can accommodate tab terminals T13 and T14, which are part of the tab terminals T11 to T14 provided on the first relay 21. In the second embodiment, the fourth to sixth terminal accommodating chambers C4 to C6 form the first terminal accommodating chamber.

The fourth terminal accommodating chamber C4 can accommodate the tab terminal T13 (part of the first terminal) of the first relay 21 installed in the first position. The first position is a position in which the X direction of the first relay 21 is parallel to the left-right direction, with tab terminal T13 on the front side and tab terminal T14 on the rear side. The fifth terminal accommodating chamber C5 can accommodate the tab terminal T13 of the first relay 21 installed in the second position. The second position is a position rotated 180° from the first position, with the X direction of the first relay 21 parallel to the left-right direction, with tab terminal T13 on the rear side and tab terminal T14 on the front side.

The sixth terminal accommodating chamber C6 can accommodate both the tab terminal T14 (the remainder of the first terminal excluding a portion of the first terminal) of the first relay 21 installed in the first position and the tab terminal T14 of the first relay 21 installed in the second position. As shown in FIG. 9, the fifth terminal accommodating chamber C5 accommodates a female terminal fitting 17 that is connected to the bus bar 16 and mates with the tab terminal T13. The bus bar 16 is provided with a terminal portion T that mates with the terminal of the fuse H.

In this embodiment, as shown in FIG. 6, the fourth terminal accommodating chamber C4 is provided on the front side of the first mounting portion 11B, and the fifth terminal accommodating chamber C5 is provided on the rear side of the first mounting portion 11B. The sixth terminal accommodating chamber C6 is provided between the fourth terminal accommodating chamber C4 and the fifth terminal accommodating chamber C5. In addition, the top surface of the first mounting portion 11B is provided with openings 111B and 112B that are elongated in the left-right direction and communicate with the fourth and fifth terminal accommodating chambers C4 and C5. The tab terminal T13 can be inserted into the fourth and fifth terminal accommodating chambers C4 and C5 through these openings 111B and 112B.

In addition, the top surface of the first mounting portion 11B is provided with an opening 113B that is elongated in the front-to-rear direction and communicates with the sixth terminal accommodating chamber C6. The tab terminal T14 can be inserted into the sixth terminal accommodating chamber C6 through this opening 113B.

The second mounting portion 12 is provided with second terminal accommodating chambers C21-C23 that can accommodate tab terminals T21-T23 provided on the second relay 22. The second mounting portion 12 is similar to the second mounting portion 12 in the first embodiment, and therefore a detailed description thereof will be omitted here. The difference between the first and second embodiments is that, while one pair (i.e., two) of second mounting portions 12 are provided in the first embodiment, two pairs (i.e., four) of second mounting portions 12 are provided in the second embodiment. In this embodiment, the second mounting portion 12 includes a front pair of second mounting portions 12, 12 (first pair of second mounting portions) arranged side by side in the left-right direction on the front side, and a rear pair of second mounting portions 12, 12 (second pair of second mounting portions) arranged side by side in the left-right direction on the rear side. The first mounting portion 11B is provided between the pair of second mounting portions 12, 12 on the front side and between the pair of second mounting portions 12, 12 on the rear side.

The third mounting portion 13 has a third terminal accommodating chamber C3 that can exclusively accommodate both the tab terminals T11 and T12 provided on the first relay 21 and the tab terminal T24 provided on the second relay 22. The third mounting portion 13 is similar to the third mounting portion 13 of the first embodiment, and therefore a detailed description thereof will be omitted here. The difference between the first and second embodiments is that, while one pair (i.e., two) of third mounting portions 13 are provided in the first embodiment, two pairs (i.e., four) of third mounting portions 13 are provided in the second embodiment. In this embodiment, the third mounting portions 13 include a front pair of third mounting portions 13, 13 (first pair of third mounting portions) arranged side by side in the left-right direction on the front side, and a rear pair of third mounting portions 13, 13 (second pair of third mounting portions) arranged side by side in the left-right direction on the rear side.

The left side (one) of the front pair of third mounting portions 13, 13 is provided between the left side (one) of the front pair of second mounting portions 12, 12 and the first mounting portion 11B. The right side (the other) of the front pair of third mounting portions 13, 13 is provided between the right side (the other) of the front pair of second mounting portions 12, 12 and the first mounting portion 11B. The left side (one) of the rear pair of third mounting portions 13, 13 is provided between the left side (one) of the rear pair of second mounting portions 12, 12 and the first mounting portion 11B. The right side (the other) of the rear pair of third mounting portions 13, 13 is provided between the right side (the other) of the rear pair of second mounting portions 12, 12 and the first mounting portion 11B.

Next, we will describe an example of how to use the relay mounting portion 1B configured as described above. First, we will describe the case where one first relay 21 is mounted on the relay mounting portion 1B and not connected to the bus bar 16. In this case, the X direction of the first relay 21 is parallel to the left-right direction, and the first relay 21 is mounted on the relay mounting portion 1 in a first position with the tab terminal T13 on the front side and the tab terminal T14 on the rear side. At this time, the tab terminal T13 is accommodated in the fourth terminal accommodating chamber C4, the tab terminal T14 is accommodated in the sixth terminal accommodating chamber C6, and the tab terminals T11 and T12 are accommodated in the front third terminal accommodating chamber C3. As shown in FIG. 7, when the first relay 21 is mounted in the first position, the second mounting portion 12, the fifth terminal accommodating chamber C5, and the pair of third mounting portions 13 on the lower side are not used.

Next, we will explain the case where one first relay 21 is mounted on the relay mounting section 1B and connected to the bus bar 16. In this case, the X direction of the first relay 21 is parallel to the left-right direction, and the first relay 21 is mounted on the relay mounting section 11 in the second position, with the tab terminal T13 at the rear and the tab terminal T14 at the front. At this time, the tab terminal T13 is accommodated in the fifth terminal accommodating chamber C5, the tab terminal T14 is accommodated in the sixth terminal accommodating chamber C6, and the tab terminals T11 and T12 are accommodated in the rear third terminal accommodating chamber C3. The tab terminal T13 accommodated in the fifth terminal accommodating chamber C5 is mated with the female terminal fitting 17 connected to the bus bar 16 and is electrically connected to the bus bar 16. As shown in FIG. 8, when the first relay 21 is mounted in the second position, the second mounting section 12, the fourth terminal accommodating chamber C4, and the upper pair of third mounting sections 13 are not used.

Next, we will explain the case where four second relays 22 are mounted on the relay mounting section 11B. Two of the four second relays 22 are mounted on the second and third mounting sections 12 and 13 on the right side of the first mounting section 11B. In this case, the second relays 22 are mounted on the relay mounting section 11B with the X direction of the second relays 22 parallel to the front-to-rear direction, with tab terminals T21 and T22 on the right side and tab terminals T23 and T24 on the left side. The remaining two of the four second relays 22 are mounted on the second and third mounting sections 12 and 13 on the left side of the first mounting section 11B. In this case, the second relays 22 are mounted on the relay mounting section 11B with the X direction of the second relays 22 parallel to the front-to-rear direction, with tab terminals T21 and T22 on the left side and tab terminals T23 and T24 on the right side.

At this time, tab terminals T21 and T22 are accommodated in the second terminal accommodating chambers C21 and C22, tab terminal T23 is accommodated in the second terminal accommodating chamber C23, and tab terminal T24 is accommodated in the third terminal accommodating chamber C3. As shown in Figure 10, when four second relays 22 are installed, the first mounting portion 11B is not used.

According to the above-described embodiment, there is no need to redesign the relay even if the specifications are changed from one in which the first relay 21 is not connected to the bus bar 16 to one in which the first relay 21 is connected to the bus bar. Furthermore, by providing the sixth terminal accommodating chamber C6 that can accommodate both the tab terminal T14 of the first relay 21 mounted in the first position and the tab terminal T14 of the first relay 21 mounted in the second position, miniaturization can be achieved.

In the above-described embodiment, the second mounting portions include a pair of second mounting portions 12, 12 on the front side and a pair of second mounting portions 12, 12 on the rear side, and the third mounting portions include a pair of third mounting portions 13, 13 on the front side and a pair of third mounting portions 13, 13 on the rear side. This allows the mounted component to be changed from the first relay 21 to four second relays 22.

In the second embodiment described above, four second relays 22 are installed, but this is not limited to this. Only one second relay 22 may be installed.

In addition, in the second embodiment described above, four second mounting sections 12 and four third mounting sections 13 are provided, but this is not limited to this. Only one, two, or three second mounting sections 12 and three third mounting sections 13 may be provided.

The present invention is not limited to the above-described embodiments, and modifications, improvements, etc. are possible as appropriate. Furthermore, the material, shape, dimensions, number, placement location, etc. of each component in the above-described embodiments are arbitrary and not limited as long as they achieve the present invention.
