Description

  The present invention relates to a connector for interconnecting with a mating connector and a board-to-board connector pair.

  A board-to-board connector pair is used to interconnect a pair of parallel circuit boards. Such a board-to-board connector is attached by tight fitting to the opposing surfaces of a pair of circuit boards so that the pair of circuit boards are electrically connected to each other.

  Chinese Patent Application Publication No. 1017777710 (Chinese Patent Application No. 2000009110006.4) discloses a board-to-board connector having the following configuration. In other words, the connector includes a plurality of first terminals and a plurality of second terminals, and each first terminal has a first contact portion disposed on one side surface of each concave insertion portion, and each concave insertion portion. The second contact portion is disposed on the side surface, and each second terminal is disposed on one side surface of each convex insertion portion so as to extend in the insertion direction of the convex insertion portion, and the first terminal of each first terminal. A first contact portion configured to contact the contact portion, and disposed on the other side surface of each convex insertion portion so as to extend in the insertion direction of the convex insertion portion, and in contact with the second contact portion of each first terminal When the convex insertion portion is inserted into the concave insertion portion, the second contact between the first contact portion and the second contact portion is pressed by the second terminal when the convex insertion portion is inserted into the concave insertion portion. The gap increases and then decreases. When the two connectors are mated, the bottom surfaces 101, 102 can separate the terminals 103, 104 from the circuit board to protect the circuit board. However, as shown in FIG. 1, since the thickness of the terminal is relatively thick, for example, 0.08 mm, the terminals 103 and 104 of the connector 10 are moved upward when the mating connector (not shown) is separated from the connector 10. Rotate (for example, rotate around the side wall portions 105 and 106 of the connector 10). Therefore, the terminals 103 and 104 may be deformed, and the terminals 103 and 104 may be defective.

  On the other hand, FIG. 2 is a cross-sectional view showing the connector 20 of another typical prior art board-to-board connector pair. As shown in FIG. 2, the terminals 201 and 202 of the connector 20 are inserted from the bottom surface and fixed by the limiting portion 203. For this reason, when the mating connector (not shown) is pulled out from the connector 20, the rotational movement of the terminals 201 and 202 is prevented, so that the deformation of the terminals 201 and 202 is prevented. However, the connector 20 has relatively thin terminals 201 and 202, and the terminals 201 and 202 move downward when the mating connector is fitted to the connector 20. For this reason, the bottom surfaces of the terminals 201 and 202 may come into contact with the circuit board 204 and affect important members on the circuit board 204.

  For this reason, the structure of the connector of the background art has two requirements, namely, preventing the connector terminal from directly contacting the circuit board when the mating connector is fitted to the connector, and the mating connector from the connector. It is not possible to satisfy simultaneously that the terminal of the connector is prevented from rotating and deforming when being pulled out.

  Therefore, in view of the above technical problem, the present invention can not only separate the connector terminal from the circuit board when the mating connector is fitted to the connector, but also the contact terminal when the mating connector is pulled out from the connector. It is an object of the present invention to provide a connector and a corresponding board-to-board connector pair that retains and restricts movement, thereby preventing terminal deformation.

  According to a first aspect of the present invention, a connector for interconnecting with a mating connector is provided. The connector includes a plurality of terminals and a housing. The housing includes a pair of end portions separated from each other, a pair of side wall portions connected to each other by the end portions, a convex portion disposed between the side wall portions and extending along the longitudinal direction of the housing, And a plurality of concave portions formed between the convex portion and the side wall portions so as to at least partially receive the plurality of terminals. Here, the convex portion has a restricting portion, and the restricting portion is used to restrict the movement of the terminal along the drawing direction of the mating connector when the mating connector is pulled out from the connector.

  Here, for example, the connector is a female connector, and the mating connector is a male connector.

  In a preferred embodiment, a bottom plate is disposed under the concave portion, and the bottom plate is used to separate the terminals from the circuit board when the mating connector is fitted into the connector.

  In a preferred embodiment, each terminal includes a holding part fixed to the outside on the side wall part, a tail part connected to the holding part, and a U-shaped contact part connected to the holding part. When the mating connector does not fit into the connector, there is a lateral gap between the head of the U-shaped contact part and the restricting part. When the mating connector is fitted into the connector, the head is positioned under the restricting part. The directional gap is reduced.

  In a preferred embodiment, the restricting portion has a flange extending from the top of the convex portion along the lateral direction of the housing.

  In a preferred embodiment, the bottom plate has a processing hole.

  According to a second aspect of the present invention, a board-to-board connector pair is provided. The board-to-board connector pair includes a connector and a mating connector configured to fit with the connector by fitting. The connector includes a plurality of terminals and a housing. The housing includes a pair of end portions separated from each other, a pair of side wall portions connected to each other by the end portions, a convex portion disposed between the side wall portions and extending along the longitudinal direction of the housing, And a plurality of concave portions formed between the convex portion and the side wall portions so as to at least partially receive the plurality of terminals. The convex portion has a limiting portion, and when the mating connector is pulled out from the connector, the limiting portion is used to limit the movement of the terminal along the pulling direction of the mating connector.

  In a preferred embodiment, a bottom plate is disposed under the concave portion, and the bottom plate is used to separate the terminals from the circuit board when the mating connector is fitted into the connector.

  In a preferred embodiment, each terminal includes a holding part fixed to the outside on the side wall part, a tail part connected to the holding part, and a U-shaped contact part connected to the holding part. When the mating connector does not fit into the connector, there is a lateral gap between the head of the U-shaped contact part and the limiting part, and when the mating connector is fitted into the connector, the head is positioned below the limiting part. The lateral gap is reduced.

  In a preferred embodiment, the restricting portion has a flange extending from the top of the convex portion along the lateral direction of the housing.

  From the embodiments of the present invention, due to the arrangement of the limiting portion and the bottom plate, the present invention can affect other members on the circuit board by preventing direct contact with the circuit board when the board-to-board connector pair is fitted. As well as preventing terminal deformation when the board-to-board connector pair is unmated. Furthermore, considering that the thickness of the terminal is relatively thin, the present invention maintains high reliability of the electrical connection by providing two contacts between the connector terminal and the mating connector terminal.

  On the other hand, in the present invention, it is necessary to change the female connector, but it is not necessary to change the male connector. Therefore, the manufacturing process can be further simplified, and there is no technical problem existing in the prior art without adverse effects. To solve easily.

  FIG. 3 is an exploded perspective view showing the connector 30 of the board-to-board connector pair according to the embodiment of the present invention.

  As shown in FIG. 3, the connector 30 is divided into a terminal portion 301 having a plurality of terminals 3011 and a housing 302 for the purpose of clarification. Here, the terminal portion 301 includes a plurality of terminals 3011. Preferably, the terminal 3011 is integrally formed by punching and bending a conductive metal plate, for example.

  The housing 302 is a main body of the connector 30 and is mainly formed of an insulating material such as a synthetic resin. The housing 302 is a substantially rectangular parallelepiped member having a substantially rectangular shape. The housing 302 includes a pair of end portions 3021 and 3022 separated from each other, and side wall portions 3023 and 3024 connected to each other by the end portions 3021 and 3022.

  The housing 302 has recesses 3025 and 3026 for receiving a mating connector (not shown) therein. Between the concave portions 3025 and 3026, a convex portion 3027 is formed integrally with the housing 302 and extends along the longitudinal direction of the housing 302. Here, although two convex portions 3027 are shown in the drawing, those skilled in the art will understand that the number of the convex portions 3027 is determined by actual requirements.

  A plurality of concave portions 3029 and 3030 are formed between the side wall portions 3023 and 3024 and the convex portion 3027 in order to at least partially receive the terminal 3011. These concave portions 3029 and 3030 may communicate with the concave portions 3025 and 3026 or a part of the concave portions 3025 and 3026.

  The top of each convex portion 3027 has a limiting portion 3031. When a mating connector (not shown) is pulled out from the connector 30, the restricting portion 3031 is used to limit the movement of the terminal 3011 along the pulling direction of the mating connector. Preferably, each restricting portion 3031 includes a flange extending from the top of the convex portion 3037 along the lateral direction of the housing 302.

  The bottom plates 3032 and 3033 are disposed in the concave portions 3029 and 3030, respectively, and are used to limit the downward movement of the terminals when the mating connector is fitted to the connector 30. Thereby, the terminal 3011 is separated from the circuit board. Similar to the convex portion 3028, the bottom plates 3032 and 3033 also extend along the longitudinal direction of the housing 302 and are respectively formed with L-shaped contours with the side wall portions 3023 and 3024. For this reason, when the mating connector is fitted to the connector 30, the movement of the terminal is simultaneously restricted by the side wall portion and the bottom plate. In other words, the terminal 3011 can only move toward the convex portion 3028. Preferably, each bottom plate 3032, 3030 further has a punch hole (not shown) formed in the bottom surface of the housing by the housing mold to form a flange.

  4 is a perspective view showing a mating connector of a board-to-board connector pair according to an embodiment of the present invention, a mating connector that fits to form a board-to-board connector pair, and the connector of FIG. . The upper side of FIG. 4 shows a mating connector 41 that fits with the connector 30 of FIG. The mating connector 41 and the connector 30 are assembled into a board-to-board connector pair 40 shown on the lower side of FIG. Hereinafter, the assembly process will be described in detail.

  FIG. 5 is a cross-sectional view showing a connector 50 of a board-to-board connector pair according to an embodiment of the present invention. The connector 50 is in a non-fitted state, that is, the connector 50 is not fitted with the mating connector.

  Specifically, as shown in the figure, the housing 501 includes bottom plates 5011 and 5012, convex portions 5013 and side wall portions 5014 and 5015. The top of the convex portion 5013 has a limiting portion 5016, and the limiting portion 5016 has a flange that extends from the top of the convex portion 5013 along the lateral direction of the housing 501. The gap formed under the flange is used for the terminals 502 and 503 to deform and move toward the convex portion 5013 when the mating connector is fitted to the connector 50. Preferably, the bottom plates 5011 and 5012 are formed integrally with the side wall portions 5015 and 5014 so as to form the concave portions 5017 and 5018. The recesses 5017 and 5018 also extend along the longitudinal direction of the housing 501 to at least partially receive the terminals 502 and 503.

  Specifically, for example, the terminal 502 includes a holding portion 5021, a tail portion 5022 on the holding portion 5021, and a U-shaped contact portion 5023 connected to the holding portion 5021. The holding portion 5021 is a portion that extends upward in the vertical direction of the housing 501 and is fixed to the side wall portion 5014 by press-fitting. The tail portion 5022 is bent so as to be connected to the holding portion 5021, extends outward along the lateral direction of the housing 501, and is connected to the circuit board by soldering or other similar means. The U-shaped contact portion 5023 is at least partially housed in the recessed portion 5018. Before the mating connector is fitted to the connector, there is a lateral gap between the head portion 5024 and the restriction portion 5016 of the U-shaped contact portion 5023.

  Similar to the terminal 502, the terminal 503 includes a holding portion 5031, a tail portion 5032 on the holding portion 5031, and a U-shaped contact portion 5033 connected to the holding portion 5031. Similarly, the holding portion 5031 is a portion that extends upward in the vertical direction of the housing 501 and is fixed to the side wall portion 5015 by press-fitting. The tail portion 5032 is bent so as to connect to the holding portion 5031, extends outward along the lateral direction of the housing 501, and is connected to the circuit board by soldering or other similar means. The U-shaped contact portion 5033 is at least partially housed in the recessed portion 5017. Before the mating connector is fitted to the connector, there is a lateral gap between the head portion 5034 and the restricting portion 5016 of the U-shaped contact portion 5033.

  6 to 8 are cross-sectional views illustrating a board-to-board fitting process according to an embodiment of the present invention.

  FIG. 6 shows a state in which the mating connector 70 starts to fit into the connector 60. Here, since the structure of the connector 60 is the same as the connector 50 of FIG. 5, the specific structure of the connector 60 will not be described in detail. Similar to the connector 50 of FIG. 5, the connector 60 includes a restriction portion 6016 and head portions 6024 and 6034 of U-shaped contact portions 6023 and 6033.

  The mating connector 70 is configured to be fitted to the connector 60 by fitting. Here, the terminals 701 and 702 of the mating connector 70 are suitable for insertion into the insertion recesses 61 and 62 formed by the substantially U-shaped contact portions 6023 and 6033.

  As illustrated, when the terminals 701 and 702 are inserted into the insertion recesses 61 and 62, the terminals 602 and 603 move downward. Furthermore, the terminals 602 and 603 are deformed and spread toward the two side walls. For this reason, the terminals 602 and 603 come closer to the convex portion 6013. As a result, the lateral gap between the terminals 602 and 603 and the restricting portion 6016 is reduced.

  FIG. 7 shows a state where the mating connector 70 is further inserted into the connector 60. As seen in FIG. 7, in contrast to FIG. 6, the terminals 701 and 702 of the mating connector 70 further enter the insertion recesses 61 and 62, so that the terminals 602 and 603 move further downward.

  Specifically, the U-shaped contact portions 6023 and 6033 of the terminals 602 and 603 are in contact with the bottom plates 6012 and 6011, respectively. For this reason, the bottom plates 6012 and 6011 restrict the downward movement of the terminals 602 and 603, respectively, and at the same time, the terminals 602 and 603 are separated from the circuit board (not shown). On the other hand, the terminals 602 and 603 continue to be deformed at that moment. Specifically, since the bottom plates 6011 and 6012 and the side wall portions 6014 and 6015 of the housing limit the movement of the terminals 602 and 603, the terminals 602 and 603 are deformed and can only move toward the convex portion 6013. Absent. Specifically, the head portions 6024 and 6034 of the U-shaped contact portions 6023 and 6033 are deformed so as to move to the space below the restricting portion 6016, that is, the gap below the restricting portion 6016, respectively. In a preferred embodiment of the present invention, the restriction 6016 comprises a laterally extending flange, and the heads 6024, 6034 enter the space below this flange.

  FIG. 8 shows a state in which the mating connector 70 is completely inserted into the connector 60. That is, the mating connector 70 is completely fitted with the connector 60.

  As shown in FIG. 8, at this moment, the bottom plates 6011 and 6012 of the connector 60 separate the terminals 602 and 603 from the circuit board, respectively, and restrict the downward movement of the terminals 602 and 603. Specifically, in contrast to FIG. 7, the heads 6024 and 6034 of the U-shaped contact portions 6023 and 6033 of the terminals 602 and 603 are spaces below the flange of the restricting portion 6016 at the top of the convex portion 6013. Further deformation to get inside. At that moment, since there are two contacts between the terminals 602 and 701 and between the terminals 603 and 702, a highly reliable electrical connection can be maintained even in the case of a relatively thin terminal.

  FIG. 9 is a diagram illustrating a process of releasing the mating of a board-to-board connector pair according to an embodiment of the present invention. As shown in FIG. 9, the mating connector 70 is pulled out from the connector 60. When the terminals 701 and 702 of the mating connector 70 move upward, the terminals 602 and 603 of the connector 60 are deformed and moved upward as a result. Specifically, since the holding portion 6021 of the terminal 602 and the holding portion 6031 of the terminal 603 are fixed to the side wall portions 6014 and 6015 of the housing, respectively, when the mating connector 70 is pulled out from the connector 60, the terminals 602 and 603 The head portions 6024 and 6034 of the U-shaped contact portions 6023 and 6033 are deformed and rotated so as to move upward. However, the flange of the restricting portion 6016 of the convex portion 6013 stops the upward movement of the head portions 6024 and 6034 and restricts and locks the head portions 6024 and 6034. Therefore, the upward movement of the terminals 602 and 603 is restricted, and the rotation and deformation of the terminals 602 and 603 are effectively prevented.

  FIG. 10 is a cross-sectional view showing a connector 80 of a board-to-board connector pair according to another embodiment of the present invention. FIG. 11 is a cross-sectional view showing a connector 90 of a board-to-board connector pair according to still another embodiment of the present invention. In contrast to the connectors shown so far in the figures, connectors 80 and 90 each have modifications to the convex portions to accommodate different manufacturing processes. Furthermore, the other structures of the connectors 80 and 90 are the same as the structure of the previous embodiment, and will not be described in detail here. Similarly, the connectors 80 and 90 can not only separate the terminal from the circuit board when the mating connector is mated with the connectors 80 and 90, but also the direction in which the mating connector is pulled out when the mating connector is pulled out from the connectors 80 and 90. Also restrict the movement of the terminal to.

  Those skilled in the art will appreciate that the above-described embodiments are not intended to limit the present invention, but are provided for explanation, and different technical structures of different embodiments may be combined to obtain technical effects. Will do. In considering the drawings, detailed description, and utility model registration claims, one of ordinary skill in the art can appreciate and implement other embodiments that have been modified based on the disclosed embodiments. For example, a person skilled in the art has two technical effects, namely, separating the terminal from the circuit board when the mating connector is fitted to the connector, and restricting the movement of the terminal when the mating connector is pulled out of the connector. The connector structure can be further modified to accomplish this. Further, the term “comprising” does not exclude other members.
