On the other hand, even if the mold is improved, the opening width of the lightening portion may not be within a predetermined value, and it is difficult to secure the moldability of the housing.

Therefore, it is an object of the present invention to provide a connector capable of ensuring the moldability of the housing.

The connector of the present disclosure includes a housing having a plurality of accommodating portions and terminal fittings accommodating in the accommodating portions, and the housing has a space portion inside a partition wall provided between the adjacent accommodating portions. It has and can be divided into a plurality of divided bodies via a divided surface passing through the space portion.

According to the present disclosure, it is possible to provide a connector capable of ensuring the moldability of the housing.

As described above, the recess 17 is arranged above the front end portion of the dividing surface 14 and below the rear end portion of the dividing surface 14. The protrusions 18 are arranged below the front end of the split surface 14 and above the rear end of the split surface 14. As shown in FIG. 5, the recess 17 and the protrusion 18 are arranged point-symmetrically with respect to the central portion of the dividing surface 14. The protruding dimension of the protrusion 18 from the divided surface 14 is set to be the same as the recessed dimension of the recess 17 from the divided surface 14.

When each of the divided bodies 11 approaches from the left-right direction and hits a portion (front and rear regions) of the divided surface 14 of each divided body 11 excluding the divided space portion 16, as shown in FIG. 4, a concave portion of one of the divided bodies 11 17 fits into the protrusion 18 of the other split body 11, and the recess 17 of the other split body 11 fits into the protrusion 18 of the other split body 11. As a result, each of the divided bodies 11 is restricted from being displaced in the vertical direction and the front-rear direction along the divided surface 14. That is, the recess 17 and the protrusion 18 function as a misalignment regulating portion. As shown in FIG. 2, in a state where the divided bodies 11 are united, the divided partition walls 15 are arranged side by side to form the partition wall 19 of the housing 10, and the divided space portions 16 are also arranged side by side to form the space portion 20 of the housing 10.

Specifically, the space portion 20 has an elongated slit shape in the front-rear direction, penetrates the partition wall 19 in the vertical direction, and the upper and lower ends are opened on the surface of the housing 10 (upper and lower surfaces of the partition wall 19).

The front and rear surfaces of the divided body 11 are arranged flatly orthogonal to the divided surface 14. As shown in FIG. 1, a slit groove-shaped mounting groove 21 extending in the vertical direction is recessed on the front and rear surfaces of the divided body 11 at a position closer to the side surface on the opposite side from the divided surface 14.

<Terminal bracket 50>
The terminal fitting 50 is integrally formed by bending a conductive metal plate or the like. As shown in FIG. 1, the terminal fitting 50 includes a base 51, a pair of elastic pieces 52 protruding upward from the base 51, and a locking portion 53 protruding upward from the base 51 along with each elastic piece 52. It has a lead portion 54 that projects laterally from the lower end of the base portion 51. The elastic pieces 52 are arranged so as to face each other. The plate surface of the locking portion 53 is orthogonal to the plate surface of each elastic piece 52, and is inserted into a locking groove (not shown) of the divided body 11 to be locked. A mating terminal 40 is inserted between the elastic pieces 52 and electrically connected. As shown in FIG. 3, the lower surface (the plate surface facing downward) of the lead portion 54 is arranged along the surface of the circuit board 90, and is connected by soldering to the conductive portion formed on the circuit board 90.

<Connecting member 60>
The connecting member 60 is a metal plate material, which is mounted on the housing 10 and holds each divided body 11 in a connected state. As shown in FIG. 1, the connecting members 60 are attached to the housing 10 in pairs so as to cover the front and rear surfaces of the housing 10. The pair of connecting members 60 have the same shape as each other.

The connecting member 60 includes a rectangular flat plate-shaped main body 61 along the vertical and horizontal directions, a mounting portion 62 that bends at a right angle from the left and right ends of the main body 61 and projects, and a mounting portion 62 from the lower end of the main body 61. It has a substrate connecting portion 63 that bends at a right angle to the opposite side and projects. The mounting portion 62 has a rectangular plate shape when viewed from the side, and is connected in the vertical direction to a portion of the main body portion 61 other than the lower end portion at the left and right ends. The board connecting portion 63 has a rectangular plate shape in a plan view, and is connected to the lower end of the main body portion 61 in the left-right direction. The lower surface (the plate surface facing downward) of the board connection portion 63 is arranged along the surface of the circuit board 90, and is soldered and fixed to the circuit board 90.

In the case of the connecting member 60 that covers the front surface of the housing 10, the mounting portion 62 projects rearward, is press-fitted into the mounting groove 21 provided on the front surface of each divided body 11, and the substrate connecting portion 63 projects forward and is arranged. In the case of the connecting member 60 that covers the rear surface of the housing 10, the mounting portion 62 projects forward, is press-fitted into the mounting groove 21 provided on the rear surface of each of the divided bodies 11, and the substrate connecting portion 63 projects rearward.

<Adjusting member 80>
The adjusting member 80 is a plate material made of resin, and is arbitrarily inserted into the space 20 in order to adjust the impedance. In the case of the present embodiment, the adjusting member 80 is press-fitted into the space 20 of the partition wall 19. By inserting the adjusting member 80 into the space portion 20, the dielectric constant of the partition wall 19 can be increased as compared with the case where the adjusting member 80 is not inserted into the space portion 20. The adjusting member 80 has a rectangular cross section elongated in the front-rear direction so as to be compatible with the space portion 20, and has a rectangular flat plate shape. For example, good transmission characteristics can be realized by preparing a plurality of types of adjusting members 80 having different dielectric constants.

<Assembly process and action>
By combining the divided bodies 11 from the left and right, the divided surfaces 14 face each other, and the protrusions 18 and recesses 17 of one split body 11 are the recesses 17 and protrusions 18 of the other split body 11, respectively. Fits and fits. As a result, the housing 10 is integrally formed. Then, the divided partition walls 15 of each divided body 11 are arranged in the width direction to form the partition wall 19, and the divided space portions 16 of each divided body 11 are arranged in the width direction to form the space portion 20. As shown in FIG. 1, the space portion 20 is arranged inside the partition wall 19 at an intermediate position between adjacent accommodating portions 12. The housing 10 has a point-symmetrical shape centered on the central portion of the partition wall 19 in a plan view.

Next, the connecting member 60 is mounted from the front and the rear so as to straddle each of the divided bodies 11. The left and right mounting portions 62 of the connecting member 60 are press-fitted into the mounting grooves 21 of each split body 11, so that the connecting member 60 is mounted on each split body 11 (housing 10). Further, by mounting the connecting member 60 across the divided bodies 11, it is possible to prevent the divided bodies 11 from being separated from each other with the divided surface 14 as a boundary.

As shown in FIG. 3, the terminal fitting 50 is housed in each housing part 12 of the housing 10. After that, the connector is installed on the surface of the circuit board 90, and the lead portion 54 of the terminal fitting 50 is soldered and connected to the conductive portion of the circuit board 90 by the reflow process. Further, the board connecting portion 63 of the connecting member 60 is also soldered to the surface of the circuit board 90 and connected. The housing 10 is fixed to the circuit board 90 via the connecting member 60.

The connector manufactured as described above can obtain good transmission characteristics due to the impedance matching action of the space 20 of the partition wall 19. Further, by inserting the adjusting member 80 into the space portion 20, the impedance can be appropriately adjusted. In this case, since the space portion 20 opens on the upper and lower surfaces of the housing 10, the adjusting member 80 can be inserted into the space portion 20 from either the upper or lower side.

Here, the space portion 20 formed inside the partition wall 19 is formed by the divided space portion 16 recessed in the divided surface 14 of each divided body 11. The divided space portion 16 has a concave shape that opens into the divided surface 14 of the divided body 11. Therefore, at the time of molding, the split space portion 16 can be easily and accurately formed by the mold for molding the split surface 14.

In the conventional case, when the connector becomes smaller and the width dimension of the partition wall 19 becomes smaller, the opening width of the space portion 20 also becomes smaller, and it becomes difficult to prepare a mold having a width dimension corresponding to the opening width of the space portion 20. There was a problem. In that respect, according to the present embodiment, even if the connector is miniaturized, the space portion 20 is formed from the divided space portion 16 formed with high accuracy as described above, so that the space portion 20 has a small opening width. However, it can be molded without any problem.

Further, since the housing 10 has a recess 17 and a protrusion 18 that regulate the misalignment of each of the split bodies 11 in the direction along the split surface 14, the misalignment of each split body 11 is referred to as the housing 10. It is not necessary to regulate by another member, and it is possible to prevent the number of parts from increasing. Further, in each of the divided bodies 11, the recesses 17 and the protrusions 18 are arranged point-symmetrically with respect to the central portion of the divided surface 14 and have the same shape, so that the troublesome assembly and component management are eliminated.

Further, since each of the divided bodies 11 is provided with a connecting member 60 that regulates the separation of the divided bodies 11 at the boundary, it is possible to prevent the divided bodies 11 from being inadvertently separated from each other. Moreover, the connecting member 60 has a board connecting portion 63 fixed to the circuit board 90, and the housing 10 is fixed to the circuit board 90 via the connecting member 60. Therefore, it is not necessary to provide a member for fixing the housing 10 to the circuit board 90 separately from the connecting member 60, and the structure of the connector can be simplified.

The housing may be composed of three or more divided bodies. In this case, the divided bodies do not have to have the same shape. For example, in the middle portion in the width direction of the housing, the divided bodies in which the divided space portions 16 are formed on both side surfaces are arranged, and the ends in the width direction of the housing. Similar to the above embodiment, it is preferable that a divided body having a divided space portion 16 formed on one side surface is arranged in the portion.
