Description

  The present invention relates to a board connecting electrical connector device that is fitted to each other in a state of being mounted on a wiring board.

  In general, in various electrical devices, an electrical connector device for board connection called a stacking connector is widely used. The board connecting electrical connector device is used, for example, by placing the second electrical connector connected to the second wiring board on the first electrical connector connected to the first wiring board so as to face each other. Then, the second electrical connector on the upper side is pushed down from the opposite state toward the first electrical connector on the lower side, so that the two electrical connectors are brought into a fitted state. Thus, the first and second wiring boards are electrically connected to each other.

  Here, the fitting between the electrical connectors described above is performed in a state in which one electrical connector is inverted up and down so as to face each other. However, in one electrical connector that is inverted up and down, Since the wiring board covers the upper part of the electrical connector, it is impossible to confirm the relative position of the upper electrical connector with respect to the electrical connector arranged on the lower side. There is a possibility that the fitting operation may be performed in a state where they are not arranged at the proper fitting position. If a fitting operation between the two electrical connectors in such an inappropriate positional relationship is performed, the fitting between the two electrical connectors is not sufficiently performed, and the fitting operation is performed in a so-called half-fitted state. It is conceivable that the electrical connectors may be completed, and there is a possibility that both electrical connectors may be poorly connected due to an impact or the like generated when the device is used.

  On the other hand, in the electrical connector device for board connection disclosed in the following cited reference 1, a pair of fitting guide portions are provided at both end portions in the connector longitudinal direction of the first and second electrical connectors, for example, The fitting guide portion at that time while bringing the other electrical connector into contact with each other at an arbitrary position of one of the electrical connectors arranged below and moving the two electrical connectors relative to each other By using this guiding action, the electrical connectors are aligned with each other to facilitate the fitting operation.

  However, in the board connecting electrical connector device having such a conventional fitting guide portion, when the two electrical connectors are brought into contact with each other in the vertical direction, it is formed by the fitting guide portion of the lower electrical connector. There is a problem that the corner of one end portion of the upper electrical connector easily falls into the recess. That is, when such a drop occurs, both electrical connectors are fitted in an inclined positional relationship with each other, and the relative movement toward the fitting position becomes difficult and unstable, and the fitting work In addition to a decrease in performance, there is a risk of damage due to collision.

The relative movement is performed while facing each other in parallel, and when the movement to the final fitting position is performed, the guided portion of the second connector comes into contact with the positioning portion of the first connector to perform positioning. Thus, as in the prior art, a situation in which the connectors are in contact with each other in an inclined state before the fitting is performed and one electrical connector is obliquely fitted into the other electrical connector is avoided.

  According to a second aspect of the present invention, the first connector includes a pair of longitudinal side wall portions extending substantially in parallel along a longitudinal direction of the first connector, and a longitudinal direction of the pair of long side wall portions. It is possible to form a short side wall portion that connects the end portions of each of the two, and the fitting guide surface is formed so as to form surfaces of the pair of long side wall portions and short side wall portions.

  Further, as in a third aspect of the invention, the positioning portion can be formed so as to protrude from the fitting guide surface in a stepped shape.

  Furthermore, as in the invention according to claim 4, the positioning portion can extend so as to form a substantially plane L shape in the longitudinal direction of the first connector and the orthogonal direction thereof.

  According to the present invention having such a configuration, as soon as the guided portion of the second connector comes into contact with the positioning portion of the first connector, both the connectors are positioned in the longitudinal direction and the orthogonal direction thereof. Thus, the fitting operation of both connectors is performed efficiently.

  On the other hand, as in the invention according to claim 5, it is possible that the guided portion is formed so as to form a part of a fixing fitting attached to both end portions in the longitudinal direction of the second connector. .

And the guided portion provided on the fixing bracket is formed to be flush with the surfaces of the long side wall portion and the short side wall portion. It is possible.

  As described above, the electrical connector device for board connection according to the present invention is provided with the positioning portion that contacts the guided portion of the second connector at one end side in the extending direction of the fitting guide surface provided on the first connector. At the same time, the other end of the fitting guide surface in the extending direction extends the fitting guide surface into a flat surface so that the positioning portion is not provided so that both electrical connectors can be fitted together. When the two electrical connectors are brought into contact with each other, the two electrical connectors are moved relative to each other while facing each other substantially parallel to the wiring board, and the guided portion of the second connector is moved from the other end portion of the fitting guide surface of the first connector to one end portion. Alignment of the fitting by sliding so as to contact the positioning part toward the direction of the contact, in the state where both connectors are inclined at the stage before the fitting is performed, as in the past One electrical connector Since it is configured so as to avoid a situation where it is obliquely fitted into the other electrical connector, it is possible to stably and easily align both electrical connectors with a simple configuration, The reliability of the electrical connector device for connection can be increased at a low cost.
