Description

  The present invention relates to a board mounting connector fixing structure for fixing a board mounting connector to a circuit board.

  Conventionally, as a board mounting connector fixing structure for fixing a board mounting connector to a circuit board, one end side of a terminal is accommodated in a connector housing of the board mounting connector so that it can be connected to a connection partner connector, Some connector housings are fixed to a circuit board by a fixing member so that the end side is arranged at a position to be mounted on the circuit board.

  For example, Patent Document 1 describes a board mounting connector fixing structure in which a fixing metal fitting (fixing member) is fixed to a printed circuit board (circuit board) by soldering.

  The connector mounting structure for mounting on a board described in Patent Document 1 is such that a fixing member can be easily attached by press-fitting into mounting grooves provided on both sides of the connector housing. When the mating connector is fitted to the connector, the backlash of the connector housing can be suppressed even when an external force is applied to the board mounting connector in the pushing direction of the mating connector.

Japanese Patent No. 4470968

  However, the board mounting connector fixing structure described in Patent Document 1 is formed so that the fixing parts of the fixing members provided on both sides of the connector housing to the circuit board protrude to the side of the connector housing. There is a problem that the arrangement space on the circuit board becomes large.

  By the way, the board mounting connector fixing structure includes a specification in which the connector housing is covered with a cover. In such a specification, the fitting hole of the connector housing is adjusted to be higher in order to secure a cover mounting portion in the connector housing. As a result, a space is created between the circuit board and the mating side end of the connector housing of the mating connector mated with the board mounting connector.

  However, such a space is a space hidden under the connector housing of the connector to be connected, which is difficult to use and is a wasteful space, so that the connector housing is fixed on the circuit board by the fixing member in a space efficient manner. I couldn't say that.

  The present invention has been made in view of the above, and can fix the connector housing on the circuit board with space efficiency by the fixing member, and can be easily attached by press-fitting the fixing member into the connector housing. It is also possible to provide a board mounting connector fixing structure that can suppress rattling of the connector housing even when an external force is applied to the board mounting connector in the pushing direction of the mating connector. To do.

  In order to solve the above-described problems and achieve the object, the board mounting connector fixing structure according to claim 1 of the present invention can connect one end side of the terminal to the connection partner connector in the connector housing of the board mounting connector. In the board mounting connector fixing structure in which the connector housing is fixed to the circuit board by a fixing member so that the other end side of the terminal is disposed at a position to be mounted on the circuit board, the fixing member is Provided on one end side is a housing-side fixing portion that becomes a portion to be fixed to the board-opposing surface that faces the circuit board of the connector housing, and on the other end side, the connection from the fitting-side end portion of the connector housing Providing a board-side fixing portion that protrudes so as to enter between the mating connector and the circuit board and serves as a portion to be fixed to the circuit board, and the connector housing A press-fit portion for press-fitting the housing-side fixing portion in the fitting direction from the inner side of the connector housing toward the fitting port side, and a portion of the housing-side fixing portion being press-fitted into the press-fit portion. A press-fit fixing portion that fixes the housing-side fixing portion on the board-facing surface, and includes a pressed surface that is a surface that abuts at a direction end position, and the housing-side fixing portion is press-fitted into the press-fit portion. A press-fit portion to be a portion to be connected, and a butting surface formed to abut against the abutted surface on the front end edge surface in the press-fit direction of the press-fit portion, and the connection partner connector to the board mounting connector When an external force is applied to the board mounting connector in the pushing direction of the connection counterpart connector, the abutting surface and the abutted surface are in contact with each other.

  In the board mounting connector fixing structure according to claim 1 of the present invention, the fixing member fixes the housing side fixing portion to the board facing surface of the connector housing, and between the connection partner connector and the circuit board. Since the board side fixing portion protruding so as to enter is fixed to the circuit board, the fixing is performed using a space between the connection partner connector fitted to the board mounting connector and the circuit board. Since the connector housing can be fixed to the circuit board without the member projecting to the side of the connector housing, the fixing member can fix the connector housing on the circuit board in a space-efficient manner. The connector can be easily installed by simply press-fitting the press-fit portion into the press-fit portion of the connector housing. Further, the abutting surface of the fixing member can be positioned to the connector housing, and further, the connector housing can be fitted with the mating connector when the connection counterpart connector is fitted to the board mounting connector. A function of preventing the connector housing from moving in the push-in direction of the connection partner connector by contacting the abutted surface of the connector housing even when a force in the push-in direction of the connection counterpart connector is applied. As a result, the connector housing can be efficiently fixed on the circuit board by the fixing member, and the fixing member can be easily attached by press-fitting into the connector housing. In addition to the board mounting connector Even when an external force in the pushing direction of the counterpart connector has been loaded can be suppressed rattling of the connector housing.

The connector housing 20 is fixed to the circuit board PB by the fixing member 10 so that the side 40b is disposed at a position where the side 40b is mounted on the circuit board PB.

First, the circuit board PB will be described.
The circuit board PB is realized by, for example, a printed wiring board. The circuit board PB forms a through hole TH for electrical connection with the terminal 40 by inserting a part of the terminal 40.
The circuit board PB has a plurality of through holes TH corresponding to the number of terminals 40.
On the circuit board PB, solder for soldering is pasted at a position for fixing a board-side fixing portion 12 (to be described later) of the fixing member 10.

Next, the fixing member 10 will be described.
The fixing member 10 is formed by subjecting a metal plate to punching or bending. The fixing member 10 is provided with a housing side fixing portion 11 which is a portion to be fixed to the board facing surface 22a which is a surface facing the circuit board PB of the connector housing 20 on one end side, and the connector housing 20 has the other end side. A board-side fixing portion 12 is provided that protrudes from the fitting-side end portion so as to enter between the connection partner connector 200 and the circuit board PB and serves as a portion to be fixed to the circuit board PB.

The board-side fixing part 12 is a hole penetrating the board-side fixing main body part 12a, and a solder filling through-hole 12b capable of filling the solder P in the hole is formed.
The solder P is used when the board-side fixing portion 12 is fixed to the circuit board PB by soldering, and is pasted on the circuit board PB as shown in FIGS.

This board side fixing | fixed part 12 is provided in a pair by connecting with each of the connection parts 13 and 13 extended in two steps from the housing side fixed main-body part 11a.
For this reason, even if one board | substrate side fixing | fixed part 12 of a pair of board | substrate side fixing | fixed parts 12 and 12 remove | deviates from the circuit board PB, the remaining board | substrate side fixing | fixed part 12 maintains a fixed state with the circuit board PB. Can be done.

Next, the connector housing 20 will be described.
The connector housing 20 has a substantially rectangular parallelepiped block shape made of insulative synthetic resin, and has a fitting port 20a formed on the surface on the mating side with the connection partner connector 200, and is directed inward from the fitting port 20a. While accommodating the one end side 40a of the some terminal 40, the accommodation space 20b for inserting the connection other party connector 200 is formed.

Of the walls forming the housing space 20 b of the connector housing 20, the wall facing the fitting port 20 a is a terminal holding wall 21 for holding a plurality of terminals 40.
The terminal holding wall 21 has a plurality of terminal press-fitting holes 21 a for press-fitting and holding the plurality of terminals 40.
Each terminal press-fitting hole 21 a is configured to hold one end side 40 a of the terminal 40 so as to protrude from the inner surface of the terminal holding wall 21 so as to connect each terminal 40 to a terminal (not shown) of the connection partner connector 200. .

  As shown in FIG. 2, the terminal 40 has a shape in which a pin-shaped conductive member is bent into an L shape. Such a terminal 40 is held by the connector housing 20 with one end side 40a facing the fitting port 20a and the other end side facing the insertion direction of the circuit board PB into the through hole TH.

Further, the connector housing 20 is provided with a fixing portion 30 for fixing the fixing member 10 to the board facing surface 22a.
The fixing portion 30 has a bottom wall 22 that forms the bottom surface of the accommodation space 20b and is spaced from the circuit board PB.
For this reason, the fixing part 30 is provided with a pair of legs 31 and 31 that support both ends of the bottom wall 22 so as to form a space between the board facing surface 22a and the circuit board PB.
In addition, the fixing portion 30 is provided with a press-fit fixing portion 32 that is fixed by press-fitting the housing-side fixing portion 11 of the fixing member 10 on the substrate facing surface 22a.

  The pair of leg portions 31, 31 are, for example, legs so as to adjust the height of the bottom wall 22 so that a cover (not shown) including a portion below the fitting port 20 a can be attached to the connector housing 20. The length is adjusted.

  The press-fit fixing part 32 includes a press-fit part 32a for press-fitting the housing-side fixed part 11 in the fitting direction from the inner side of the connector housing 20 toward the fitting port 20a, and a part of the housing-side fixed part 11 is press-fitted. The housing side fixing portion 11 is fixed including the abutting surface 34 that is a surface that abuts on the end position in the press-fitting direction to the portion 32a.

The press-fit portion 32a has press-fit grooves 33, 33 provided in pairs so as to press-fit the press-fit piece portions 11bb of the pair of press-fit piece portions 11bb, 11bb.
Each press-fit groove 33 has a groove size adjusted so that each press-fit piece portion 11bb can be press-fitted with an appropriate force and a predetermined holding force can be obtained with respect to each press-fit piece portion 11bb. ing.
More specifically, as shown in FIG. 5B, the press-fit groove 33 includes a groove bottom surface 33a and a pair of groove facing surfaces 33b facing each other, and the pair of groove facing surfaces 33b and 33b. Is adjusted to be slightly smaller than the plate thickness of the press-fitting piece portion 11bb.

The abutted surface 34 is a surface that is provided at the end of the press-fit direction of the press-fit portion 32a so as to be orthogonal to the press-fit direction.
More specifically, it is a surface provided at the end portion in the press-fitting direction of the pair of press-fit grooves 33, 33 so as to be orthogonal to the press-fitting direction.

Such a press-fit fixing portion 32 is fitted into the pair of press-fit grooves 33, 33 until the abutting surfaces 11c abut against the abutted surfaces 34 while press-fitting the pair of press-fit piece portions 11bb, 11bb. The fixing member 10 can be fixed at a predetermined position of the connector housing 20.
For this reason, the fixing member 10 can be easily fixed to the connector housing 20 simply by press-fitting the press-fit portion 11b into the press-fit portion 32a.

The abutting surface 11 c of the fixing member 10 not only has a positioning function for the fixing member 10.
The abutting surface 11c is provided to the connector housing 20 even when an external force is applied to the connector housing 20 in the pushing direction of the connector mating connector 200 when the connector mating connector 200 is fitted to the board mounting connector 100. When the contact surface 34 abuts, the connector housing 20 has a function of preventing the connector mating connector 200 from moving in the pushing direction.
That is, the abutting surface 11 c also has a function of preventing the connector housing 20 from rattling.

  In such a board mounting connector fixing structure 1, the fixing member 10 fixes the housing side fixing portion 11 to the board facing surface 22 a of the connector housing 20 and protrudes so as to enter between the connection partner connector 200 and the circuit board PB. Since the board-side fixing portion 12 is fixed to the circuit board PB, the connector housing 20 is fixed to the circuit board PB without the fixing member 10 projecting to the side of the connector housing 20 as shown in FIG. Can be done.

Next, an assembly procedure of the board mounting connector fixing structure 1 will be described with reference to FIGS.
FIG. 7 is a view showing how the fixing member 10 is attached to the connector housing 20. FIG. 8 is a diagram illustrating a state in which the plurality of terminals 40 are attached to the connector housing 20. FIG. 9 is a diagram illustrating a state in which the connector housing 20 assembled with the fixing member 10 and the plurality of terminals 40 is fixed to the circuit board PB. FIG. 10 is a view showing a state in which the connection partner connector 200 is fitted to the board mounting connector 100.
In FIG. 7B, the fixing member 10 that has been attached to the connector housing 20 is indicated by a virtual line.

First, the operator attaches the fixing member 10 to the connector housing 20 (see FIG. 7). Here, the operator abuts each abutting surface 11c against each abutting surface 34 while press-fitting the pair of press-fitting pieces 11bb and 11bb of the fixing member 10 into the pair of press-fitting grooves 33 and 33 of the connector housing 20. Until the fixing member 10 is fixed at a predetermined position.
The operator can easily fix the connector member 20 to the connector housing 20 simply by press-fitting the fixing member 10 in this manner.
Moreover, since the direction in which the fixing member 10 is press-fitted is the fitting direction and is the direction from the inner side of the connector housing 20 toward the fitting port side, the terminal 40 mounting operation and the connector housing 20 direction, which are the next work steps, are performed. It is possible to work with equality. Thereby, since it can move to the next work process, without changing direction of connector housing 20, work efficiency is improving.

  Thereafter, the worker attaches the plurality of terminals 40 to the connector housing 20 (see FIG. 8). Here, the operator fixes each terminal 40 to the connector housing 20 by press-fitting each terminal 40 into the corresponding terminal press-fitting hole 21a.

  Thereafter, the operator fixes the connector housing 20 to which the fixing member 10 and the plurality of terminals 40 are attached to the circuit board PB (see FIG. 9). Here, the operator inserts the end portions of the plurality of terminals 40 into the corresponding through holes TH, and on the solder P pasted on the circuit board PB by the board-side fixing section 12 of the fixing member 10. The connector housing 20 is positioned on the circuit board PB while being positioned so as to be placed.

Thereafter, the solder P is melted by applying heat to the solder P at a temperature at which the solder P melts, and the melted solder P is cooled and solidified to solder the board-side fixing portion 12 to the circuit board PB.
As a result, the solder P is filled not only between the circuit board side surface of the board side fixing part 12 and the circuit board PB but also in the solder filling through holes 12b penetrating the board side fixing main body part 12a. Since it is solidified, the fixing member 10 and the circuit board PB are more strongly coupled.

  The assembly work of the board mounting connector fixing structure 1 is completed through the above steps, and the connector mating connector 200 can be fitted into the board mounting connector 100 by fitting into the accommodating space 20b (FIG. 10). reference).

  In the board mounting connector fixing structure 1 according to the embodiment of the present invention, the fixing member 10 fixes the housing side fixing portion 11 to the board facing surface 22a of the connector housing 20, and between the connection partner connector 200 and the circuit board PB. Since the board-side fixing portion 12 protruding so as to enter is fixed to the circuit board PB, a fixing member is used by utilizing the space between the connection partner connector 200 fitted to the board mounting connector 100 and the circuit board PB. Since the connector housing 20 can be fixed to the circuit board PB without projecting to the side of the connector housing 20, the connector housing 20 is fixed on the circuit board PB by the fixing member 10 in a space efficient manner. The fixing member 10 press-fits the press-fit portion 11b into the press-fit portion 32a of the connector housing 20. Can be easily attached to the connector housing 20, and the abutting surface 11 c of the fixing member 10 has a positioning function to the connector housing 20, and further, when the mating connector 200 is fitted to the board mounting connector 100. Even if an external force in the pushing direction of the connection partner connector 200 is applied to the connector housing 20, the abutting surface 34 of the connector housing 20 abuts, so that the connector housing 20 moves in the pushing direction of the connection counterpart connector 200. As a result, the connector housing 20 can be space-efficiently fixed on the circuit board PB by the fixing member 10 and the fixing member 10 is press-fitted into the connector housing 20. Can be installed easily by Duck, it is possible to suppress rattling of even the connector housing 20 even when an external force in the pushing direction of the counterpart connector 200 to the substrate mounting connector 100 is loaded.

  Moreover, since the board mounting connector fixing structure 1 according to the embodiment of the present invention fixes the connector housing 20 to the circuit board PB by one fixing member 10, the number of components can be reduced.

  In the board mounting connector fixing structure 1 according to the embodiment of the present invention, the solder P is not only provided between the circuit board PB side surface of the board side fixing main body 12a and the circuit board PB, but also the board side fixing main body. Since the solder filling through hole 12b penetrating the portion 12a can be solidified, the fixing member 10 and the circuit board PB can be strongly coupled by soldering.

(Modification 1)
Next, Modification 1 of the board mounting connector fixing structure 1 according to the embodiment of the present invention will be described with reference to FIGS.
FIG. 11 is a view showing the board mounting connector fixing structure 2 of Modification 1 so as to correspond to FIG. FIG. 12 is a cross-sectional view of the periphery of the pair of press-fitting protrusions 15 and 15 of the board mounting connector fixing structure 2 of the first modification. FIG. 13 is a perspective view of the fixing member 14 shown in FIG.
In the board mounting connector fixing structure 2 according to the first modified example, the fixing member 14 is not only sandwiched between the pair of groove facing surfaces 33b and 33b of each pressed insertion groove 33 of the connector housing 20, but the pair of pressed insertion grooves 33, It differs from the board mounting connector fixing structure 1 of the embodiment in that it is held by the connector housing 20 by being sandwiched between the groove bottom surfaces 33a of 33.
Other configurations are the same as those in the embodiment, and the same components as those in the embodiment are denoted by the same reference numerals.

In the board mounting connector fixing structure 2 of Modification 1, a pair of press-fitting protrusions 15 and 15 are provided on the fixing member 14.
The press-fitting projections 15 of the pair of press-fitting projections 15, 15 are grooves of each press-fitting groove 33 from each press-fitting piece portion 11 bb in a state where the pair of press-fitting piece portions 11 bb, 11 bb are press-fitted into the pair of press-fitting grooves 33, 33. It is formed so as to protrude toward the bottom surface 33a.

As shown in FIG. 11A, the fixing member 14 has a width W1 connecting the apexes of the pair of press-fitting protrusions 15 and 15 to an interval W2 between the groove bottom surfaces 33a of the pair of press-fit grooves 33 and 33 of the connector housing 20. The dimensions are adjusted so as to be slightly larger.
Therefore, when the fixing member 14 press-fits the pair of press-fit piece portions 11bb and 11bb into the pair of press-fit grooves 33 and 33, the press-fit piece portions 11bb are not only sandwiched by the press-fit groove 33 in the plate thickness direction. The pair of press-fit protrusions 15 and 15 are sandwiched by the groove bottom surfaces 33a of the pair of press-fit grooves 33 and 33 in the width direction connecting the apexes of the pair of press-fit protrusions 15 and 15.

  The board mounting connector fixing structure 2 of Modification 1 has the same effects as the board mounting connector fixing structure 1 of the embodiment, and the fixing member 14 is opposed to a pair of grooves of the respective press-fit grooves 33 of the connector housing 20. In addition to being sandwiched by the surfaces 33b and 33b, the pair of press-fit grooves 33 and 33 are also sandwiched by the groove bottom surfaces 33a, so that the holding force of the pair of press-fit grooves 33 and 33 to the fixing member 14 can be further increased. As a result, the rattling prevention effect of the connector housing 20 can be enhanced.

(Modification 2)
Next, modification 2 of the board mounting connector fixing structure 1 according to the embodiment of the present invention will be described with reference to FIGS.
FIG. 14 is a view showing the board mounting connector fixing structure 3 of Modification 2 so as to correspond to FIG. FIG. 15 is a cross-sectional view of the periphery of the pair of locking projections 17 and 17 of the board mounting connector fixing structure 3 according to the second modification.
In the board mounting connector fixing structure 3 according to the second modification, when the connection partner connector 200 is pulled out from the connector housing 23 in order to release the connector fitting, the connector housing 23 moves in the pull-out direction of the connection partner connector 200. Is different from the board mounting connector fixing structure 1 of the embodiment in that it is blocked by the fixing member 16.
Other configurations are the same as those in the embodiment, and the same components as those in the embodiment are denoted by the same reference numerals.

  In the board mounting connector fixing structure 3 according to the second modified example, a pair of locking projections 17 and 17 are provided on the fixing member 16, and a pair of elastic projections that are locked to the connector housing 23 by the pair of locking projections 17 and 17, respectively. Locking projections 35 are provided.

Each locking protrusion 17 of the pair of locking protrusions 17, 17 is a state where the pair of press-fitting piece portions 11 bb, 11 bb are press-fitted into the pair of press-fitting grooves 33, 33, and each press-fitting groove 33 from each press-fitting piece portion 11 bb. It is formed so as to protrude toward the groove bottom surface 33a.
Each locking projection 17 is orthogonal to the press-fitting direction of the fixing member 16 and comes into contact with the corresponding elastic locking projection 35 of the connector housing 23, so that the connector housing 23 moves in the pulling-out direction of the mating connector 200. A movement restricting wall surface 17a to be blocked is formed.

Each elastic locking projection 35 of the pair of elastic locking projections 35, 35 is locked to the corresponding locking projection 17 using elastic deformation. The pair of elastic locking projections 35 and 35 are provided at the pressure inlet side end portions of the respective press-fit grooves 33.
Such a pair of elastic locking projections 35 is elastic so that when the pair of press-fitting pieces 11bb and 11bb are press-fitted into the pair of press-fit grooves 33 and 33, the pair of locking projections 17 and 17 are passed over. The pair of locking projections 17 and 17 are locked by being deformed and elastically restored after the pair of locking projections 17 have passed over.

  The board mounting connector fixing structure 2 of this modification 2 has the same effect as the board mounting connector fixing structure 1 of the embodiment, and an external force that moves the connector housing 23 in the pulling direction of the mating connector 200 is applied. In this case, the movement restricting wall surfaces 17a of the pair of locking projections 17 and 17 are in contact with the pair of elastic locking projections 35 and 35, thereby preventing the connector housing 23 from moving in the direction in which the mating connector 200 is pulled out. As a result, the effect of preventing the connector housing 23 from rattling can be enhanced.

  The board mounting connector fixing structures 1, 2, and 3 according to the embodiment and the first and second modifications of the present invention are such that the fixing members 10, 14, and 16 are filled with solder P in the solder filling through holes 12b. Although what fixed to the board | substrate PB was illustrated, you may fix by not only this but another fixing method. For example, the fixing members 10, 14, and 16 may be fixed to the circuit board PB by soldering without forming the solder filling through-holes 12b. The fixing members 10, 14, and 16 may be fixed by screws instead of soldering. You may fix to the circuit board PB.

  In addition, the board mounting connector fixing structures 1, 2, and 3 according to the embodiment and the first and second modifications of the present invention are such that the fixing members 10, 14, and 16 are attached to the circuit board PB by the pair of board-side fixing portions 12 and 12. Although what was fixed was illustrated, it is not restricted to this. For example, like the fixing member 18 shown in FIG. 16, it may be fixed to the circuit board PB by one board side fixing portion 19.

  The invention made by the present inventor has been specifically described based on the above-described embodiments of the invention. However, the present invention is not limited to the above-described embodiments of the invention and does not depart from the gist thereof. Various changes can be made.
