Description

  The present disclosure relates to electrical connectors.

  For example, as shown in Patent Document 1, an electrical connector that electrically connects boards (board-to-board) is known. In the electrical connector described in Patent Document 1, the connection work for bringing the electrical connectors connected to the respective substrates into a fitted state is facilitated by providing a guide portion.

JP 2008-84795 A

  Here, when the connector in the fitted state is pulled out by a human hand, for example, it is conceivable that only one of the pair of long sides of the connector to be pulled out is pulled upward (tilting is performed). In this case, at the time of removal, the other side is inclined downward by the amount that one side of the connector to be removed is lifted upward, and the other side and the area of the mating connector interfere with each other and exert a force. It will be added. As a result, both connectors may be damaged.

  Thus, the present disclosure describes an electrical connector that prevents damage during removal.

  An electrical connector according to an aspect of the present disclosure includes a first connector that is electrically connected to the first board, and a second connector that is electrically connected to the second board and fitted to the first connector. The first connector has a pair of guide portions that extend in the fitting direction and guide insertion / removal of the second connector with respect to the first connector, and the second connector is fitted with the first connector. The guide portion has a guided portion disposed between the pair of guide portions in the combined state, and the pair of guide portions guides the guide portion to be removed while being inclined toward the guide portion in the fitted state.

  In the electrical connector according to the present disclosure, the guided portion of the second connector is removed from the first connector while being inclined toward the guide portion of the first connector. For example, for a board-to-board connector, it is recommended that the connector be pulled out vertically. When pulled out vertically, both connectors do not interfere (or are difficult to interfere) at the time of removal, and therefore it is possible to suppress an excessive force from being applied to both connectors. However, when pulling out by a human hand, for example, it is conceivable that only one side of a pair of long sides of the connector to be pulled out is pulled upward (tilting is performed). In this case, at the time of removal, the other side is inclined downward by the amount that one side of the connector to be removed is lifted upward, and the other side and the counterpart connector interfere with each other and apply force. It will be. As a result, both connectors may be damaged. In this regard, as described above, in the electrical connector according to the present disclosure, the guide portion of the first connector is removed while the fitted portion to be fitted is inclined toward the guide portion. That is, in the electrical connector according to the present disclosure, the first connector is provided with a pair of guide portions so that the guided portion in a state of being tilted by tilting or the like is smoothly extracted. As a result, it is possible to suppress damage to the connector due to interference between the two connectors, which has been a problem when removing the tilt.

  In the electrical connector described above, a gap is formed between the inner surface of at least one guide portion and the outer surface of the guided portion in the fitted state, and the guided portion is displaced in a direction toward the gap portion. May be inclined toward the guide portion. In this way, the gap between the guides when the guide part is pulled out so as to incline toward the guide part is formed, so that the interference between both connectors when the side part is removed is formed. It can suppress more effectively.

  The first connector has a first fixing bracket that fixes the first connector to the first board and a pair of guide portions, and the second connector fixes the second connector to the second board. You may have the 2nd fixing metal fitting in which the to-be-guided part was formed. By forming the guide part and the guided part on a metal member (fixing bracket), the strength of these parts can be increased, and the connector can be prevented from being damaged even if they interfere with each other during removal. can do.

  The first fixing bracket may have a convex portion protruding in the fitting direction between the pair of guide portions, and the second fixing bracket may have a concave portion that engages with the convex portion. Thereby, the fitting force can be improved at the time of fitting of the first connector and the second connector.

  The guided portion can be inclined toward one guide portion of the pair of guide portions in the fitted state, and the convex portion is formed on the surface facing the concave portion in the fitting direction. The protrusion amount of the region near one guide portion is larger than the protrusion amount of the region near the other guide portion, and a slope is formed from the region near one guide portion toward the region near the other guide portion. Also good. By forming such a slope on the convex portion, in a state where the convex portion and the concave portion are engaged, the region near the other guide portion in the convex portion (that is, in the direction in which the guided portion in the convex portion is inclined). There will be a gap between the area near the guide part on the opposite side of the one guide part and the surface of the concave part facing the convex part. As a result, at the time of removal, a region near the one guide portion (region where the protruding amount is large) of the convex portion is brought into contact with the opposing surface of the concave portion, and the guided portion is directed to one guide portion with the corresponding contact surface as a fulcrum. Therefore, the concave portion of the guided portion can easily be moved over the region of the convex portion near the other guide portion. In other words, when the tilt is removed, the inclined guided portion can be more easily removed.

  In the fitted state, the guided portion can be inclined toward one of the pair of guide portions, and the second fixing bracket further includes a pair of arm portions that define the recess, The arm portion has a first arm portion extending along one guide portion in the fitted state, and a second arm portion extending along the other guide portion of the pair of guide portions in the fitted state, The second arm portion is a restriction that regulates the inclination angle of the guided portion with respect to the guide portion within a certain range by contacting the other guide portion when the guided portion is inclined toward the one guide portion. May have a part. In this way, the restriction portion of the guided portion at the time of removal comes into contact with the guide portion on the opposite side (the other side) of the one guide portion in the inclined direction and the inclination angle is limited. It can suppress effectively that other members etc. are damaged by inclining too much.

  The first arm portion has elasticity and may be configured to be displaceable in a direction facing the one guide portion. Thereby, at the time of extraction, the guided portion can be inclined more easily toward one guide portion.

  According to the present disclosure, it is possible to prevent the connector from being damaged at the time of removal.

By forming the portion 120 and the space 37d, the second fixing bracket 80 can be inclined toward the guide portion 37 (details will be described later). That is, by forming the gap portion 120 and the like, the second fixing bracket 80 can be inclined toward the guide portion 37 of the pair of guide portions 37 and 38.

(State during connector removal operation)
Next, the state of the connector during the connector removal operation will be described with reference to FIG. The connector removal operation described here refers to an operation of removing the plug connector 70 fitted to the receptacle connector 10 from the receptacle connector 10, and more specifically, wiring for mounting the plug connector 70 by a human hand or the like, for example. This refers to an operation of pulling out the plug connector 70 by pulling upward together with the substrate 90. When the plug connector 70 is pulled out in this way, one of the long sides of the plug connector 70 (for example, the side wall portion 74) may be pulled upward (tilting is performed). Below, the state of the connector apparatus 1 of this embodiment is demonstrated about the case where tilt extraction is performed.

  At the time of the connector removal operation, as shown in FIG. 7, the wiring board 90 is pulled up obliquely upward. As a result, the second fixing fitting 80 of the plug connector 70 mounted on the wiring board 90 is inclined in the direction of the guide portion 37 while being displaced in the direction toward the gap portion 120. Specifically, the second fixing metal member 80 is inclined (rotated) toward the guide portion 37 with the third portion 88c of the arm portion 88 engaged with the lower surface of the second portion 39b of the convex portion 39 as a fulcrum. Even when the second fixing bracket 80 is inclined as described above, the gap portion 120 for allowing the arm portion 88 to escape and the space 37d for releasing the base portion 87 are formed. Displacement is not hindered. Further, at least the arm portion 88 has elasticity and can be displaced in a direction facing the guide portion 37. Accordingly, the second fixing fitting 80 can be smoothly inclined with the third portion 88c of the arm portion 88 as a fulcrum. Further, on the upper surface of the convex portion 39, an inclined surface is formed which slopes downward as it goes from a region near one guide portion 37 to a region near the other guide portion 38. The amount of protrusion in the direction is reduced. Thereby, when the 2nd fixing metal fitting 80 rotates using the 3rd part 88c of the arm part 88 as a fulcrum, it can be set as the structure which the arm part 89 which divides the recessed part 100 tends to get over the convex part 39. FIG. In this way, the pair of guide portions 37 and 38 guides the second fixed fitting 80 in the fitted state to be removed while being inclined toward the guide portion 37. The arm portion 89 is formed such that the outer surface thereof abuts against the inner surface of the guide portion 38 when the second fixing metal member 80 is inclined at a predetermined angle or more. That is, the arm portion 89 functions as a restricting portion that restricts the inclination angle of the second fixing bracket 80 within a certain range.

(Function and effect)
Next, the effect of the connector apparatus 1 (electric connector) mentioned above is demonstrated.

  The connector device 1 includes a receptacle connector 10 that is electrically connected to the wiring board 50, and a plug connector 70 that is electrically connected to the wiring board 90 and fitted to the receptacle connector 10. Has a pair of guide portions 37 and 38 that extend in the Z direction (fitting direction) and guide insertion / removal of the plug connector 70 with respect to the receptacle connector 10, and the plug connector 70 is fitted with the receptacle connector 10. The second fixing bracket 80 is disposed between the pair of guide portions 37, 38, and the pair of guide portions 37, 38 is inclined while the second fixing bracket 80 in the fitted state is inclined toward the guide portion 37. Guide you to be removed.

  In the connector device 1, the pair of guide portions 37, 38 are connected to the second fixing bracket so that the second fixing bracket 80 of the plug connector 70 is removed from the receptacle connector 10 while being inclined toward the guide portion 37 of the receptacle connector 10. Guide 80. For example, for a board-to-board connector, it is recommended that the connector be pulled out vertically. When pulled out vertically, both connectors do not interfere (or are difficult to interfere) at the time of removal, and therefore it is possible to suppress an excessive force from being applied to both connectors. However, when pulling out by a human hand, for example, it is conceivable that only one side of a pair of long sides of the connector to be pulled out is pulled upward (tilting is performed). In this case, at the time of removal, the other side is inclined downward by the amount that one side of the connector to be removed is lifted upward, and the other side and the counterpart connector interfere with each other and apply force. It will be. As a result, both connectors may be damaged. In this regard, as described above, in the connector device 1, the guide portions 37 and 38 of the receptacle connector 10 guide the second fixed fitting 80 in the fitted state to be removed while being inclined toward the guide portion 37. In other words, in the connector device 1, the pair of guide portions 37 and 38 are provided in the receptacle connector 10 so that the second fixing metal member 80 that is inclined by the tilting or the like is smoothly removed. As a result, it is possible to suppress damage to the connector due to interference between the two connectors (receptacle connector 10 and plug connector 70), which has been a problem when removing the tilt.

  In the connector device 1, a gap portion 120 that is a gap is formed between the inner surface of the guide portion 37 and the outer surface of the second fixing bracket 80 in the fitted state, and the second fixing bracket 80 is formed in the gap portion 120. It is inclined toward the guide portion 37 by being displaced in the direction of heading. As described above, the gap 120 is formed as a space (gap) through which the second fixing bracket 80 is released when the second fixing bracket 80 is removed so as to be inclined toward the guide portion 37. Interference between both connectors when performing extraction can be more effectively suppressed.

  In the connector device 1, the receptacle connector 10 has a first fixing fitting 30 that fixes the receptacle connector 10 to the wiring board 50 and is formed with a pair of guide portions 37, 38. The plug connector 70 includes the plug connector 70. It has the 2nd fixing metal fitting 80 in which the to-be-guided part was formed while fixing to the wiring board 90. By forming the guide part and the guided part on a metal member (fixing bracket), the strength of these parts can be increased, and the connector can be prevented from being damaged even if they interfere with each other during removal. can do.

  In the connector device 1, the first fixing bracket 30 has a convex portion 39 protruding in the Z direction between the pair of guide portions 37 and 38, and the second fixing bracket 80 has a concave portion 100 that engages with the convex portion 39. Have. Thereby, the fitting force can be improved when the receptacle connector 10 and the plug connector 70 are fitted.

  In the connector device 1, the second fixing fitting 80 can be inclined toward one guide portion 37 of the pair of guide portions 37, 38 in the fitted state, and the convex portion 39 is a concave portion in the Z direction. On the surface facing 100, the protrusion amount of the region near one guide portion 37 of the pair of guide portions 37, 38 is larger than the protrusion amount of the region near the other guide portion 38, and is closer to one guide portion 37. A slope is formed from the region toward the region near the other guide portion 38. By forming such a slope on the convex portion 39, in a state where the convex portion 39 and the concave portion 100 are engaged, a region near the other guide portion 38 in the convex portion 39 (that is, the second portion of the convex portion 39 A gap is formed between the area near the guide portion 38 on the opposite side of the one guide portion 37 in the direction in which the fixing metal member 80 is inclined and the surface of the concave portion 100 facing the convex portion 39. As a result, at the time of removal, the region near the one guide portion 37 (region where the protruding amount is large) of the convex portion 39 is brought into contact with the opposing surface of the concave portion 100, and the second fixing bracket 80 is moved to one side with the corresponding contact surface as a fulcrum. Therefore, the concave portion 100 can easily be moved over the region of the convex portion 39 near the other guide portion 38. In other words, when the tilt is removed, the inclined guided portion can be more easily removed.

  In the connector device 1, the second fixing bracket 80 further includes a pair of arm portions 88 and 89 that define the recessed portion 100, and the pair of arm portions 88 and 89 extends along the one guide portion 37 in the fitted state. The arm portion 88 extends and the arm portion 89 extends along the other guide portion 38 in the fitted state. The arm portion 89 is formed when the second fixing bracket 80 is inclined toward the one guide portion 37. By contacting the other guide portion 38, it functions as a restricting portion that restricts the tilt angle of the second fixing bracket 80 within a certain range. As described above, the arm portion 89 of the second fixing bracket 80 abuts against the guide portion 38 on the opposite side (the other side) of the one guide portion 37 in the inclined direction at the time of removal, and the inclination angle is limited. Further, it is possible to effectively prevent other members and the like from being damaged when the second fixing fitting 80 is excessively inclined.

  In the connector device 1, the arm portion 88 has elasticity and is configured to be displaceable in a direction facing the one guide portion 37. Thereby, at the time of extraction, the second fixing bracket 80 can be smoothly inclined with the third portion 88c of the arm portion 88 as a fulcrum. That is, the second fixture 80 can be more easily inclined toward the one guide portion 37.

  Although the embodiment has been described above, the present invention is not limited to the above embodiment. For example, a gap portion 120 is formed between the inner surface of the guide portion 37 and the outer surface of the second fixing bracket 80 in the fitted state, and the second fixing bracket 80 is displaced in the direction of the gap portion 120 by being displaced. Although it described as inclining toward the part 37, it is not limited to this. That is, at least one of the guide part and the guided part may have a spring property so that the guided part is allowed to tilt toward the guide part. Moreover, although it demonstrated that the 2nd fixing metal fitting 80 can incline toward the one guide part 37 in the combined state, it is not limited to this, A to-be-guided part can incline toward both of a pair of guide parts. It may be a thing.
