Japanese Patent No. 5964673

  According to the configuration disclosed in Patent Document 1, the connector is installed on the surface of the substrate so that the first female terminal is connected to the first male terminal mounted on the surface of the substrate. And the 2 male terminal which is an external terminal penetrates a board | substrate and is connected to a 2nd female terminal. Thereby, an external terminal and a board | substrate can be connected via a connector.

  However, according to the configuration disclosed in Patent Document 1, since the connector is installed on one surface of the substrate, the connector protrudes greatly from the substrate. Therefore, realization of a connector that can reduce the amount of protrusion from the substrate is desired. Also, it is desired to realize a board with a connector that includes such a connector and can reduce the amount of protrusion from the board.

  An object of this invention is to provide the connector and board | substrate with a connector which can reduce the protrusion amount from a board | substrate in view of the said situation.

(1) A connector according to an aspect of the present invention for achieving the above object is a connector that connects a board and an external terminal, and a connector terminal portion that is connected to the board and the external terminal; A housing portion for holding a connector terminal portion, and the housing portion is installed on the substrate in a state of projecting from the both sides of the substrate through the substrate in the height direction thereof. It is configured.

  According to the connector of this configuration, the housing portion that holds the connector terminal portion connected to the external terminal is installed on the substrate in a state where the housing portion penetrates the substrate in the height direction and protrudes from both sides of the substrate. For this reason, the housing portion is installed on the substrate in a state where one portion in the height direction protrudes from one surface of the substrate and the other portion in the height direction protrudes from the other surface of the substrate. That is, the entire housing portion is not installed on the substrate in a state of protruding from one surface of the substrate, and the portion where the housing portion protrudes from the substrate in the height direction is efficiently disposed in the space on both sides of the substrate. It can be arranged to distribute. Therefore, according to said structure, the protrusion amount from the board | substrate of the housing part of a connector can be reduced.

  Therefore, according to said structure, the connector which can reduce the protrusion amount from a board | substrate can be provided.

(2) The connector terminal portion includes a substrate mounting portion that is mounted on the surface of the substrate and connected to the substrate, and the position of the substrate mounting portion in a direction parallel to the height direction of the housing portion is: The position corresponding to between the both ends of the height direction of the said housing part may be sufficient.

  According to this configuration, the housing part penetrates the board in the height direction and protrudes from both sides of the board, and the board mounting part of the connector terminal part is disposed at a corresponding position between both ends of the housing part in the height direction. In this state, the connector is installed on the board. Therefore, according to said structure, even if it is a case where a connector terminal part is a connector mounted in the surface of a board | substrate, the protrusion amount from a board | substrate can be reduced.

  Also, in general, when the connector terminal is mounted on the board by soldering the connector terminal to the surface of the board, the terminal is used to check whether or not the solder mounting is properly performed. Inspection of the mounting part on the substrate surface is performed. Such inspection is usually performed using a general-purpose image inspection apparatus. In some cases, a plurality of connectors are mounted on the surface of the board in a state of being close to each other due to a request for a circuit configuration or an installation space. That is, a plurality of connectors may be mounted on the surface of the board with a narrow pitch. As described above, even when the connector terminals are mounted on the surface of the substrate in a state where the plurality of connectors are close to each other, it is necessary to inspect the mounting portion of each connector terminal on the substrate surface. However, in this case, if the amount of protrusion of the connector housing from the board is large as in the configuration disclosed in Patent Document 1, the effect of the adjacent connector housing in the mounting portion of the terminal on the board and the surrounding area thereof. Therefore, it becomes difficult to inspect the mounting portion of the terminal on the board.

  However, according to the above configuration, even when a plurality of connectors are installed on the board in a state of being close to each other, the amount of protrusion of each connector from the board can be reduced. For this reason, in the board | substrate mounting part of a connector terminal part and the area | region of the periphery, it can suppress that the shadow by the housing part of an adjacent connector arises, and can test | inspect the board | substrate mounting part of a connector terminal part easily. Conventionally, when a shadow is caused by a housing of an adjacent connector and it is difficult to inspect the mounting portion of the terminal on the board by using a general-purpose image inspection apparatus, an expensive dedicated inspection using X-rays A device is required. However, according to the above configuration, the amount of protrusion of each connector from the board can be reduced, shadowing by the housing part of the adjacent connector can be suppressed, and the board mounting part of the connector terminal part can be easily inspected. Therefore, the necessity of using an expensive dedicated inspection device using X-rays can be greatly reduced.

  Moreover, according to said structure, when a some connector is installed in a board | substrate in the state which adjoined mutually, there can exist an advantageous effect also from the viewpoint of the process in a reflow furnace. In general, when the mounting portion of the connector terminal is mounted on the surface of the substrate by soldering, first, paste-like solder is applied to a predetermined portion of the surface of the substrate, and the applied paste-like solder is placed on the applied paste-like solder. The mounting part is placed. And the board | substrate and connector in the state by which the mounting part was mounted on the solder are heated in a reflow furnace, and a solder once fuse | melts. Thereafter, the substrate and the connector are cooled, and the solder is solidified. As a result, the mounting of the mounting portion of the connector terminal on the substrate surface by soldering is completed, and the installation of the connector on the substrate is completed.

  However, when a plurality of connectors are installed on the board in a state of being close to each other, if the amount of protrusion of the connector housing from the board is large as in the configuration disclosed in Patent Document 1, transmission by convection in the reflow furnace is performed. Heat tends to be insufficient. That is, in the region where the solder on which the terminal mounting portion is placed and the region around it, the adjacent connector housing hinders heat transfer due to convection in the reflow furnace and becomes insufficient. The heating of is likely to be insufficient. For this reason, when a plurality of connectors are installed on the board in a state of being close to each other, heat treatment by increasing the heating capacity of the reflow furnace or convection in the reflow furnace is performed as a measure for heating the solder to the target temperature. Measures to promote this are necessary.

  However, according to the above configuration, even when a plurality of connectors are installed on the board in a state of being close to each other, the amount of protrusion of each connector from the board can be reduced. For this reason, during the processing in the reflow furnace, in the area where the solder on which the board mounting part of the connector terminal part is placed and the area around it are disposed in the reflow furnace by the housing part of the adjacent connector. It can suppress that the heat transfer by a convection becomes inadequate. Thereby, according to said structure, the treatment conventionally required in order to heat a solder to target temperature becomes unnecessary. That is, it is not necessary to increase the heating capacity of the reflow furnace and to promote heat transfer by convection in the reflow furnace. For this reason, according to said structure, even if it is a case where several connectors are installed in a board | substrate in the state which mutually adjoined, a reflow furnace can be used and a solder can be heated to target temperature at low cost.

  Moreover, according to said structure, according to the capability of a reflow furnace, the board | substrate mounting arrange | positioned in the position corresponding to between the both ends of the height direction of a housing part so that the protrusion amount from the board | substrate of a connector may be reduced. The position of the part can also be set. That is, according to the above configuration, even when a plurality of connectors are installed on the substrate in a state of being close to each other, the solder is heated from the connector substrate so as to heat the solder to the target temperature according to the capability of the reflow furnace. The amount of protrusion can be reduced.

  Furthermore, according to the above configuration, even when a plurality of connectors are installed on the board in a state of being close to each other, heat transfer by convection in the reflow furnace is reduced by reducing the protruding amount of the connector from the board. The solder can be efficiently heated to the target temperature. For this reason, the mounting density of the connector in a board | substrate can be increased. That is, according to the above configuration, the connector having the reflow furnace capacity as a factor even if the mounting density of the connector on the board is limited due to the reflow furnace capacity as a limiting factor. The restrictions on the mounting density can be relaxed. As a result, even when a reflow furnace having the same capacity is used, more connectors can be mounted in a narrower space on the board than in the past.

(3) The connector terminal portion includes a first terminal mounted and connected to the substrate including the substrate mounting portion, and a second terminal connected to the first terminal and connected to the external terminal. The second terminal is connected to the first terminal connected to the first terminal at an end of the first terminal opposite to the board mounting portion, and to the external terminal. A second contact portion, and a connecting portion that integrally connects the first contact portion and the contact portion, and the connecting portion is elastically deformed to cause the second contact portion of the first contact portion. You may be comprised as a spring part which accept | permits the relative displacement with respect to a contact part.

  According to this configuration, the connector terminal portion includes the first terminal mounted on the substrate and the second terminal connected to the first terminal and the external terminal, and the second terminal is the first terminal side first terminal. 1 contact part, the 2nd contact part by the side of an external terminal, and the connection part as a spring part between the 1st contact part and the 2nd contact part. For this reason, even if the vibration generated on the external terminal side and the vibration generated on the substrate side are vibrations having different vibration forms, the vibration of the different vibration forms is directly caused by the elastic deformation of the connecting portion. Transmission is suppressed. That is, even if vibrations with different vibration forms occur on the external terminal side and the substrate side, most of the vibrations are absorbed by the elastic deformation of the connecting portion, and the vibrations with different vibration forms are not directly transmitted. Is done. For this reason, the possibility of fatigue failure occurring in the first contact portion and the second contact portion can be reduced, and the vibration resistance of the connector can be improved. And according to the connector of said structure, while providing the connection part as a spring part between a 1st contact part and a 2nd contact part in a 2nd terminal, aiming at an improvement in vibration resistance, and reducing the protrusion amount from a board | substrate You can also That is, according to said structure, while having a vibration absorption structure, the connector which can also reduce the protrusion amount from a board | substrate can be provided.

(4) The connecting portion is configured to be disposed on one side of the substrate in a state where the housing portion penetrates the substrate and protrudes from both sides of the substrate, and the second contact portion is The housing portion may be configured to be disposed on the other side of the substrate in a state of penetrating the substrate and projecting from both sides of the substrate.

  According to this configuration, since the connecting portion is arranged on one side of the substrate and the second contact portion connected to the external terminal is arranged on the other side of the substrate, the second terminals are efficiently distributed to the spaces on both sides of the substrate. Can be arranged. And the part which accommodates the 2nd terminal in a housing part can be arrange | positioned so that it may distribute efficiently to the space of the both sides of a board | substrate. Thereby, the further reduction of the protrusion amount from the board | substrate in the connector which has a vibration absorption structure can be aimed at. Moreover, according to said structure, an external terminal is connected to the 2nd contact part arrange | positioned at the other side of the board | substrate which is the other side of the connection part arrange | positioned at one side of a board | substrate. For this reason, it is not necessary to connect the external terminal to the second terminal while greatly penetrating the substrate, and the length of the external terminal can be shortened. By reducing the length of the external terminal, it is possible to prevent the structure including the substrate, the connector, and the external terminal from increasing in size in the height direction.

(5) The housing portion may include a guide portion that guides a direction in which the external terminal connected to the connector terminal portion is inserted.

  According to this configuration, since the guide portion that guides the direction in which the external terminal connected to the connector terminal portion is inserted is provided in the housing portion, the connection work between the connector and the external terminal can be easily performed. According to the connector configured as described above, it is possible to facilitate the work of connecting the external terminals and reduce the amount of protrusion from the substrate.

Installed. For this reason, the housing portion 10 is installed on the substrate 100 in a state where one portion in the height direction protrudes from one surface of the substrate 100 and the other portion in the height direction protrudes from the other surface of the substrate 100. The That is, the entire housing portion 10 is not installed on the substrate 100 in a state of protruding from one surface of the substrate 100, and the portion of the housing portion 10 that protrudes from the substrate 100 in the height direction is not It can be arranged so that it is efficiently distributed to the space on both sides. Therefore, according to this embodiment, the protrusion amount from the board | substrate 100 of the housing part 10 of the connector 1 can be reduced.

  Therefore, according to this embodiment, the connector 1 and the board | substrate 2 with a connector which can reduce the protrusion amount from the board | substrate 100 can be provided.

  Further, according to the present embodiment, the housing part 10 penetrates the board 100 in the height direction and protrudes from both sides of the board 100, and the board mounting parts 51 of the connector terminal part 15 are both end parts of the housing part 10 in the height direction. The connector 1 is installed with respect to the board | substrate 100 in the state arrange | positioned in the position corresponding between. Therefore, according to the present embodiment, even when the connector terminal portion 15 is the connector 1 mounted on the surface of the substrate 100, the amount of protrusion from the substrate 100 can be reduced.

  Moreover, according to this embodiment, even if it is a case where the some connector 1 is installed in the board | substrate 100 in the state which mutually adjoined, the protrusion amount from the board | substrate 100 of each connector 1 can be reduced. For this reason, in the board | substrate mounting part 51 of the connector terminal part 15, and the area | region of the periphery, it can suppress that the shadow by the housing part 10 of the adjacent connector 1 arises, and the test | inspection of the board | substrate mounting part 51 of the connector terminal part 15 is easy. It can be carried out.

  FIG. 21 is a perspective view showing a state in which a plurality of connectors 1 are installed on the board 100. 21A is a perspective view illustrating the board 100 and the plurality of connectors 1 with the female housing 12 of the connector 1 facing upward. On the other hand, FIG. 21B is a perspective view illustrating the board 100 and the plurality of connectors 1 with the guide housing 14 of the connector 1 facing upward. 22 is a side view of the connector 1 and the board 100 shown in FIG. 21 and 22 exemplify a form in which two connectors 1 are installed on the board 100 as an example of a form in which the plurality of connectors 1 are installed on the board 100.

According to this embodiment, even if it is a case where the some connector 1 is installed in the board | substrate 100 in the state which mutually adjoined, the protrusion amount from the board | substrate 100 of each connector 1 can be reduced. For this reason, at the time of processing in the reflow furnace, reflow is performed by the housing portion 10 of the adjacent connector 1 in the region where the solder on which the board mounting portion 51 of the connector terminal portion 15 is placed and the surrounding region. It can suppress that the heat transfer by the convection in a furnace becomes inadequate. Thereby, according to this embodiment, the treatment conventionally required for heating the solder to the target temperature becomes unnecessary. That is, it is not necessary to increase the heating capacity of the reflow furnace and to promote heat transfer by convection in the reflow furnace. For this reason, according to this embodiment, even if it is a case where the some connector 1 is installed in the board | substrate 100 in the state which mutually adjoined, a reflow furnace can be used and a solder can be heated to target temperature at low cost.

The amount of protrusion from the substrate 100 can be reduced.

  Furthermore, according to the present embodiment, even when the plurality of connectors 1 are installed on the board 100 in a state of being close to each other, the amount of protrusion of the connector 1 from the board 100 is reduced, so that The heat can be efficiently transferred by convection and the solder can be efficiently heated to the target temperature. For this reason, the mounting density of the connector 1 in the board | substrate 100 can be increased. In other words, according to the present embodiment, the connector having the capacity of the reflow furnace as a factor, according to the present embodiment, even if the mounting density of the connector on the board is limited by the capacity of the reflow furnace. 1 can be relaxed. Thereby, even if the reflow furnace of the same capability is used, more connectors 1 can be mounted in a narrower space in the substrate 100 than in the past.

And have. For this reason, even if the vibration generated on the external terminal 101 side and the vibration generated on the substrate 100 side are vibrations having different vibration forms, the connecting portion 56 is elastically deformed to have different vibration forms. It is suppressed that vibration is transmitted directly. That is, even if vibrations with different vibration forms occur on the external terminal 101 side and the substrate 100 side, most of the vibrations are absorbed by the elastic deformation of the connecting portion 56, and vibrations with different vibration forms are directly transmitted. It is suppressed. For this reason, the possibility of fatigue failure occurring in the first contact portion 54 and the second contact portion 55 can be reduced, and the vibration resistance of the connector 1 can be improved. And according to this embodiment, while providing the connection part 56 as a spring part between the 1st contact part 54 and the 2nd contact part 55 in the 2nd terminal 22, it aims at improvement in vibration resistance, and it protrudes from the board | substrate 100. FIG. The amount can also be reduced. That is, according to the present embodiment, it is possible to provide the connector 1 and the connector-equipped substrate 2 that have a vibration absorbing structure and can reduce the amount of protrusion from the substrate 100.

  Further, according to the present embodiment, the connecting portion 56 is disposed on one side of the substrate 100, and the second contact portion 55 connected to the external terminal 101 is disposed on the other side of the substrate 100. It can arrange | position so that it may distribute efficiently to the space of the both sides of the board | substrate 100 (refer FIG. 6). And the part which accommodates the 2nd terminal 22 in the housing part 10 can be arrange | positioned so that it may distribute efficiently to the space of the both sides of the board | substrate 100. FIG. Thereby, the further reduction of the protrusion amount from the board | substrate 100 in the connector 1 which has a vibration absorption structure can be aimed at. In addition, according to the present embodiment, the external terminal 101 is connected to the second contact portion 55 disposed on the other side of the substrate 100 that is opposite to the connecting portion 56 disposed on one side of the substrate 100. For this reason, it is not necessary to connect the external terminal 101 to the second terminal 22 in a state where it penetrates the substrate 100 greatly, and the length of the external terminal 101 can be shortened. Since the length of the external terminal 101 can be shortened, it is possible to suppress an increase in the dimension of the structure including the substrate 100, the connector 1, and the external terminal 101 in the height direction.

  Further, according to the present embodiment, since the housing 10 is provided with the guide housing (guide portion) 14 for guiding the direction in which the external terminal 101 connected to the connector terminal portion 15 is inserted, the connector 1 and the external terminal 101 Can be easily connected.
