In the board A with connector, the connector 7 is sandwiched and fixed between the board 1 and the upper case 3 with the connecting portion 7a exposed from the upper case 3, as shown in FIG.

Each part of the board | substrate A with a connector is demonstrated in detail.
4A to 4C are diagrams showing a part of the board 1, the connector 7, and the mounting component 5 of the connector-attached board A, where (a) is a perspective view, (b) is a cross-sectional view, c) is a top view.
As shown in FIGS. 4A to 4C, the connector 7 is arranged on the substrate 1, and the mounting components 5 are arranged in an integrated state around the connector 7.
The substrate 1 is a known circuit substrate such as a glass epoxy substrate or a metal core substrate having circuit patterns formed on both sides. The board 1 is appropriately formed with a positioning hole 1a (see FIG. 3) for positioning the connector 7 at a planned mounting location 8 of the connector 7 and a through hole (not shown) for inserting and fixing a terminal 6 described later. Yes.
As shown in FIG. 4B, the connector 7 includes a resin connector housing 2 and metal terminals 6 press-fitted and fixed to the connector housing 2.

The connector housing 2 includes a leg 2b that can stand on the board 1, a connection opening 2a disposed on the leg 2b, and a press-fit fixing formed between the connection opening 2a and the leg 2b. Part 2c.
The connection opening 2a is formed in a frame shape that opens upward in the vertical direction with respect to the substrate surface of the substrate 1, and the leg portion 2b is formed in a frame shape that opens in the lower direction in the vertical direction with respect to the substrate surface of the substrate 1. Yes. Two or more positioning projections 2h for positioning the connector 7 on the board 1 are formed at the lower part of the leg 2b.
The press-fit fixing portion 2c serves as a partition wall that partitions the internal space between the connection opening 2a and the leg 2b, and communicates with the internal space of each of the connection opening 2a and the leg 2b so that the terminal 6 can be press-fitted and fixed. The press-fitting hole 2d is provided.
As can be seen from FIGS. 4A to 4C, the peripheral wall 2f of the connection opening 2a has a portion formed to protrude from the peripheral wall 2g of the leg 2b. It is arranged in a state where a part thereof is located in an empty space that is adjacent to the leg portion 2b side by side under the opening 2a. Here, the connector 7 and the mounting component 5 are not in direct contact.
Ribs 2e are formed on the peripheral wall 2f of the connection opening 2a. As shown in FIG. 3, the rib 2 e is formed at a position overlapping the peripheral edge of the opening 3 a of the upper case 3 in the direction perpendicular to the substrate surface of the substrate 1. The rib 2e is formed so as to be substantially in contact with the peripheral edge of the opening 3a of the upper case 3.

The terminal 6 is press-fitted and fixed in a press-fitting hole 2d formed in the press-fitting fixing part 2c so as to communicate with the internal space of the connection opening 2a and the leg 2b. Further, the terminal 6 is inserted into a through hole (not shown) of the substrate 1 and fixed by soldering in the same manner as the mounting component 5 at a portion protruding from the substrate 1 to the back surface.
A connecting portion 7 a of the connector 7 is formed by the tip portion of the terminal 6 extending above the substrate 1 and the opening connecting portion 2 a of the connector housing 2.

The mounting component 5 is various components mounted on the substrate 1. For example, a relay is shown here, but the bus bar, capacitor, resistor, and the like are not particularly limited.
As shown in FIG. 1, the upper case 3 is a cover that covers the entire top surface of the substrate 1, so that the connection portions 7 a of the connector 7 are exposed to the upper surface side of the upper case 3. While having the opening 3a formed independently, it has the latching convex part 3x which carries out lock fixation with respect to the lower case 4. As shown in FIG. As shown in FIG. 1, the protrusion length of the connecting portion 7a of the connector 7 can be adjusted by appropriately changing the height of the upper surface of the upper case 3 and forming the opening 3a at each location. .
The lower case 4 is a cover that covers the entire lower surface of the substrate 1, and has a locking projection 4 x of the upper case 3 and a locking recess 4 x that forms a pair of locking mechanisms.

Next, the manufacturing method of the board | substrate A with a connector is demonstrated.
First, the terminal 6 is press-fitted and fixed in the press-fitting hole 2 d of the press-fitting fixing portion 2 c of the connector housing 2, thereby forming a connector 7.
Next, the mounting component 5 is disposed on the substrate 1, and the connector 7 is disposed on the substrate 1 (the mounting component 5 is disposed first because there is a portion that enters the lower side of the connector 7). At this time, the positioning projection 2h of the connector housing is fitted into the positioning hole 1a on the substrate 1 to prevent displacement. The terminal 6 of the connector 7 is inserted into the through hole.
In this state, the flow soldering process is performed, and the terminals 6 are fixed by soldering to the substrate 1, so that the connectors 7 and the substrate of the mounting component 5 are mounted as shown in FIGS. 4 (a) to 4 (c). 1 is positioned and fixed.
Next, the upper side of the substrate 1 to which the mounting component 5 and the connector 7 are fixed in this way is covered with the upper case 3. At this time, each of the connection portions 7a of the plurality of connectors 7 is exposed from the openings 3a formed independently. The lower side of the substrate 1 is covered with the lower case 4.
And the latching convex part 3x of the upper case 3 and the latching recessed part 4x of the lower case 4 are latched, and it completes as the board | substrate A with a connector.

The first characteristic of the above-described board A with connector is that the plurality of connectors 7 on the board 1 are not screwed to the board 1 but are soldered between the board 1 and the terminals 6 and sandwiched between the board 1 and the upper case 3. It is only fixed.
The connector 7 is positioned by fitting the positioning projection 2h of the leg 2b of the connector housing 2 into the positioning hole 1a of the board 1 and fitting the connecting portion 7a with the opening 3a.
In this structure, when the connection portion 7a of the connector 7 is connected to another connector (not shown), the connection pressure is received by the connection portion between the leg portion 2b of the connector housing 2 and the board 1, and conversely When another connector (not shown) is removed from the connecting portion 7a of the connector 7, the pressure is received by the connecting portion between the rib 2e of the connector housing 2 and the upper case 3, and in either case, the terminal 6 and the board No extra force is applied to the soldering part with 1.
By adopting such a structure, first, the screwing operation of the board 1 and the connector 7 can be abolished. As a result, the manufacturing time can be shortened, and the cost can be reduced by reducing the number of parts.
As can be seen from FIGS. 1 and 2, the connection portion 7 a of the connector 7 is directed vertically upward with respect to the substrate surface of the substrate 1, so that not only the peripheral portion of the substrate 1 but also the central portion or the vicinity thereof. Since the connectors 7 can be arranged, the number of connectors 7 that can be arranged on one substrate 1 and the degree of freedom of arrangement can be secured.
In addition, since several terminals 6 are held for each connector 7 and the plurality of connectors 7 are configured independently of each other, the positioning accuracy of the terminals 6 with respect to the substrate 1 can be easily obtained, and based on environmental temperature changes. It is also preferable that the soldered portion of the terminal 6 is not easily damaged by expansion and contraction.
Further, if the connector 7 is standardized in some predetermined shapes, there is an advantage that the board A with connector can be easily manufactured by arbitrarily laying them out on the board 1.
The various effects as described above are exhibited to the maximum when all the connectors 7 on the substrate 1 are fixed by one upper case 3.

The next characteristic of the above-mentioned board A with connector is that the mounting component 5 is arranged on the board 1 adjacent to the connector 7, and a part of the mounting part 5 is below the connection portion 7 a of the connector 7. It is arrange | positioned in the state located in the side.
Conventionally, since the connecting portion 7a of the connector 7 tends to be larger than the leg portion 2b side, the space below the connecting portion 7a has been wasted. On the other hand, in the present embodiment, by adopting the configuration as described above, the mounting component 5 and the connector 7 can be integrated, and the board A with connector can be reduced in size.

Further, the above-described board A with connector is characterized in that the peripheral wall 2f or 2g of the connector housing 2 overlaps with the peripheral edge of the opening 3a of the upper case 3 in the direction perpendicular to the board surface of the board 1. In addition, the rib 2e is formed.
According to such a structure, as described above, when another connector (not shown) is removed from the connecting portion 7a of the connector 7, the pressure is received by the connecting portion between the rib 2e of the connector housing 2 and the upper case 3. This is preferable because an extra force is not applied to the soldered portion between the terminal 6 and the substrate 1.

Further, the above-described board A with connector is more characteristic in that it has a positioning hole 1a on the board 1, a positioning protrusion 2h is formed on the leg 2b of the connector 7, and the positioning protrusion 2h is formed in the positioning hole 1a. It is inserted.
Such a structure is preferable because the connector 7 is positioned on the substrate 1 and the connector 7 is prevented from being displaced when the connector 7 is soldered to the substrate 1.

In addition, the board | substrate with a connector of this invention is not limited to embodiment mentioned above, It can take a various aspect.
For example, although the upper case 3 is fixed using the lower case 4 in the above-described embodiment, the upper case 3 can be directly fixed to the substrate. It is also possible to use a plurality of upper cases 3.
Although the connector 7 has shown the example which connects another connector here, components, such as a fuse and a relay, may be fixed, for example.
The opening 3a of the upper case 3 is preferably provided independently for each connector 7 in order to ensure that the connector 7 is sandwiched between the substrate 1 and the upper case 3; By doing so, it is also possible to have a structure in which one opening 3a is provided for a plurality of connectors 7.
In addition, the upper case 3 can be bent and pressed against the connector 7 to bring the rib 2e and the peripheral edge of the case opening 3a into close contact with each other. In this case, the connector 7 is stably held. preferable.

  As described above, according to the present invention, it is possible to provide a board with a connector that can shorten the manufacturing time, reduce the component cost, and reduce the number of connectors and the restriction on the arrangement.
