Abstract
The invention provides a connector for a substrate. A connector (1) for a substrate has a connector body (1p) and a detachment prevention mechanism (7). The detachment prevention mechanism is engaged with an engagement portion (3e) of the substrate in a state where an end portion (3p) of the substrate (3) is inserted into an insertion portion (1s) of the connector body, thereby preventing the substrate from being detached from the insertion portion.
Description
The application takes Japanese patent application 2019-015610 (application date: 2019, 1 and 31) as a basis and enjoys the priority of the basic application. The present application incorporates the entire contents of the base application by reference thereto.
Technical Field
Embodiments of the present invention relate to a connector for a substrate.
Background
Conventionally, for example, a board connector that is provided on a main board and into which an end portion of an extension board can be inserted is known. The substrate connector includes: a connector body having an insertion portion; a pair of holding arms extending in parallel with each other from both sides of the connector main body; and a projection provided at a projecting end (tip) of each holding arm. On the other hand, concave portions into which the convex portions of the holding arms can be engaged are provided on both sides of the extension board.
Here, the end portion of the extension board is inserted into the insertion portion of the connector body. Then, the convex portion engages with the concave portion. At this time, the engagement state of the convex portion and the concave portion is maintained by the elastic force of the holding arm itself. In this way, the extended substrate is held by the pair of holding arms so as to sandwich both sides thereof, and thereby the extended substrate is electrically connected to the substrate connector.

However, in the conventional board connector described above, both sides of the flat extended board are held between the pair of holding arms. In this state, for example, depending on the magnitude of external pressure or external vibration applied to the substrate connector and the expansion substrate, the engagement state between the convex portion and the concave portion may be released, and as a result, the expansion substrate may be separated or further dropped from the substrate connector.
Disclosure of Invention
The invention provides a connector for a substrate, which can prevent an extension substrate clamped by a pair of holding arms at two sides from separating (falling off).
According to an embodiment, a connector for a substrate includes a connector body and a detachment prevention mechanism. The separation preventing mechanism is configured to be capable of preventing the substrate from separating from the insertion portion by fitting the substrate into the fitting portion of the substrate in a state where the end portion of the substrate is inserted into the insertion portion of the connector body.

Detailed Description
[ constitution of one embodiment ]
Fig. 1 is a configuration diagram of an arrangement of a substrate connector 1 (hereinafter, referred to as a connector) according to an embodiment. In fig. 1, the connector 1 is provided on a main board 2 (circuit board) as an example. The main board 2 is built in a desktop computer, a notebook computer, or a tablet terminal, and is configured to be capable of mounting electronic components such as a power supply, a CPU, and a memory. The connector 1 is configured to be able to electrically connect the main board 2 and another board 3 (hereinafter, referred to as an extension board).
The extended substrate 3 is a flat rectangular plate and has a front surface 3a and a back surface 3 b. The extension board 3 has an end portion 3p that can be inserted into the connector 1, and side surfaces 3s provided on both sides of the extension board 3 with the end portion 3p interposed therebetween. On both side surfaces 3s of the extension board 3, concave portions 4 into which convex portions 6 described later can be engaged are provided in advance. For example, the recess 4 is formed by recessing a portion of the side surface 3s in a rectangular shape.
As shown in fig. 1, the connector 1 includes a connector body 1p, a holding arm 5, and a projection 6. The connector body 1p is electrically connected to the main board 2, and has an insertion portion 1s into which an end portion 3p of the extension board 3 can be inserted. The holding arms 5 project from both sides of the connector body 1p in parallel with each other. The protruding portions 6 are provided at the protruding ends of the holding arms 5, and when the end portion 3p of the extension board 3 is inserted into the insertion portion 1s of the connector body 1p, the protruding portions 6 engage with the recessed portions 4. In the example of fig. 1, a pair of holding arms 5 project parallel to the main plate 2. In this case, the extension board 3 is inserted obliquely with respect to the connector body 1p (insertion portion 1 s).
Fig. 2 is a holding state diagram of the extension substrate 3. In fig. 2, the extension board 3 is held by the connector 1 in a positional relationship parallel to the main board 2, for example. Here, according to the holding step of the extension board 3, first, the extension board 3 is tilted with respect to the main board 2, and the end portion 3p of the extension board 3 is inserted into the connector main body 1p (insertion portion 1s) (see fig. 1).
Subsequently, the extension substrate 3 is displaced so as to be parallel to the main board 2. At the same time, the pair of holding arms 5 are elastically deformed, and the protruding ends (projections 6) of the holding arms 5 are separated from each other. Then, when the extension board 3 is in a positional relationship parallel to the main board 2, the elastic deformation of the holding arm 5 is released.
Then, as shown in fig. 2, the holding arm 5 is elastically deformed into the original shape by its own restoring force. At this time, the convex portion 6 of the holding arm 5 engages with the concave portion 4 of the extension substrate 3. In the example of fig. 2, in the engaged state of the convex portion 6 and the concave portion 4, a part (for example, the tip portion 6p) of the convex portion 6 engaged with the concave portion 4 is pressed against the surface 3a of the extension substrate 3.
In this state, the extension substrate 3 is held by the pair of holding arms 5 so as to sandwich both sides thereof. This suppresses the displacement operation of the extension board 3 in the direction of rising (tilting) from the main board 2 (see fig. 1). As a result, the extension board 3 is held by the connector 1 in a positional relationship parallel to the main board 2.
However, the engagement state between the convex portion 6 and the concave portion 4 may be released depending on the degree of external pressure or external vibration acting on the connector 1 or the extension board 3. For example, the extension board 3 may be detached or dropped from the connector 1 in a direction parallel to the main board 2. Therefore, the connector 1 is provided with a detachment prevention mechanism 7 (see fig. 3), and the detachment prevention mechanism 7 can prevent detachment (falling-off) of the extension board 3 sandwiched between the pair of holding arms 5 on both sides.
Fig. 3 is a structural diagram of the detachment prevention mechanism 7. The detachment prevention mechanism 7 uses a fitting portion 3e (see fig. 1, 2, and 4) provided in advance on the extension board 3. The fitting portion 3e is formed to extend from the front surface 3a to the rear surface 3b of the extension board 3. In fig. 1, 2, and 4, the fitting portion 3e is configured as a through hole 3e that penetrates from the front surface 3a to the back surface 3b of the extended substrate 3, as an example. The shape and size of the fitting portion (through hole) 3e are set according to the type and size of the extended substrate 3, for example, and therefore are not particularly limited herein. The shape of the fitting portion (through hole) 3e can be assumed to be various shapes such as a circle, a triangle, and a rectangle.
As shown in fig. 3, the separation prevention mechanism 7 includes a separation prevention body 7p and an insertion structure 8. As a material of the retaining body 7p, for example, any of a metal material and a resin material can be applied. The retaining body 7p and the fitting structure 8 may be integrally molded with each other, or may be separately molded, and the fitting structure 8 is mounted on the retaining body 7 p.
The retaining body 7p is formed in a cantilever shape having elasticity. The retaining body 7p has a base end supported by the connector 1 and a distal end serving as a free end. In the example of fig. 3, the retaining body 7p is disposed between the pair of holding arms 5. In this case, the retaining body 7p has a base end supported by the facing surface 5s of the holding arm 5 and extends parallel to the holding arm 5 (facing surface 5s) from the base end to the tip end. The facing surface 5s is an inner surface 5s of the pair of holding arms 5 extending in parallel and in a mutually facing positional relationship.
The fitting structure 8 is provided at the tip (free end) of the retaining body 7 p. The fitting structure 8 has a contour that can be fitted into the fitting portion (through hole) 3e of the extension substrate 3. The fitting structure 8 continuously rises from the front end (free end) of the retaining body 7p in a direction away from the main plate 2 (see fig. 1). Here, when the fitting portion (through hole) 3e has a circular shape, the fitting structure 8 has a contour (for example, a cylindrical shape or a columnar shape) that can be fitted into the circular fitting portion (through hole) 3 e. In this case, the diameter of the cylindrical (columnar) fitting structure 8 is preferably set to be the same as or slightly smaller than the inner diameter of the circular fitting portion (through hole) 3 e.
Fig. 4 is a schematic diagram showing an engagement step of the detachment prevention mechanism 7 (the detachment prevention body 7p, the fitting structure 8) and the fitting portion (the through hole) 3 e. As shown in fig. 4, the extension board 3 is inclined with respect to the main board 2 (see fig. 1), and the end portion 3p of the extension board 3 is inserted into the connector body 1p (insertion portion 1 s). The fitting structure 8 is positioned at a position where the fitting portion (through hole) 3e can be fitted during the insertion.
Next, the extension board 3 is displaced so as to be parallel to the main board 2, and the convex portions 6 of the holding arms 5 are engaged with the concave portions 4 of the extension board 3. At this time, both sides of the extension board 3 are held by the pair of holding arms 5. At the same time, the fitting structure 8 is fitted into the fitting portion (through hole) 3e (see fig. 5).
Fig. 5 is a schematic view showing a state in which the fitting structure 8 of the detachment prevention mechanism 7 is fitted to the fitting portion (through hole) 3e of the extension substrate 3. As shown in fig. 5, in the fitted state, the cylindrical (columnar) fitting structure 8 is in contact with the circular fitting portion (through hole) 3e without a gap. This can prevent the extension board 3 from coming off the connector body 1p (insertion portion 1 s). As a result, the connection state between the end portion 3p of the extension board 3 and the metal terminal 9 of the connector body 1p (insertion portion 1s) is maintained fixed. In the example of fig. 5, the biasing spring 10 incorporated in the connector body 1p (the insertion portion 1s) is inserted into the end portion 3p of the extension board 3 of the connector body 1p (the insertion portion 1s) and is constantly pressed toward the metal terminal 9.
[ Effect of one embodiment ]
As described above, according to the present embodiment, the detachment prevention mechanism 7 is provided, thereby preventing the extension substrate 3, which is sandwiched between the holding arms 5 on both sides, from being detached (dropped). In this case, even when external pressure or external vibration acts on the connector 1 or the expansion board 3, the engagement state between the convex portion 6p of the holding arm 5 and the concave portion 4 of the expansion board 3 is maintained fixed. Thereby, the connection state between the end portion 3p of the extension substrate 3 and the metal terminal 9 of the connector main body 1p (insertion portion 1s) is maintained fixed. As a result, the electrical connection state between the connector 1 and the extension board 3 can be maintained constant for a long period of time.
According to the present embodiment, the upper contour of the fitting structure 8 is formed in an arc shape (see fig. 5). In this case, the arc-shaped curved surface can be used as the guide portion 8 g. Thus, when the insertion structure 8 is inserted into the insertion portion (through hole) 3e of the extension board 3, the insertion structure 8 can be smoothly guided toward the insertion portion (through hole) 3e by the arc-shaped guide portion 8 g.
According to the present embodiment, by providing the separation prevention mechanism 7, it is possible to eliminate the play (clearance, margin) between the end portion 3p of the extended board 3 and the connector main body 1p (insertion portion 1 s). In this case, when external pressure or external vibration is applied to the connector 1 or the extension board 3, the end portion 3p of the extension board 3 and the metal terminal 9 of the connector body 1p (the insertion portion 1s) do not rub against each other. This can reduce or suppress wear of the end portion 3p of the extension board 3 and the metal terminal 9 of the connector body 1p (insertion portion 1 s).

Fig. 6 is a sectional view of an embedded structure 8 of modification 1. As shown in fig. 6, the fitting structure 8 of the present modification has a contour that can be fitted into the fitting portion (through hole) 3e of the extension substrate 3. The fitting structure 8 continuously rises from the front end (free end) of the retaining body 7p in a curved shape in a direction separating from the main plate 2 (see fig. 1).

This can prevent the extension board 3 from coming off the connector body 1p (insertion portion 1 s). As a result, the connection state between the end portion 3p of the extension board 3 and the metal terminal 9 of the connector body 1p (insertion portion 1s) is maintained fixed. Other configurations and operational effects are the same as those of the above embodiment, and therefore, the description thereof is omitted.

The guide portion 8g has the same function as the guide portion 8g of the above embodiment.
As described above, according to the modification 2, the pressing portion 8f presses the extended substrate 3 toward the insertion portion 1s of the connector 1 (connector main body 1p) in a state where the fitting structure 8 of the detachment prevention mechanism 7 is fitted to the fitting portion (through hole) 3e of the extended substrate 3. This can prevent the extension board 3 from coming off the connector body 1p (insertion portion 1 s). As a result, the connection state between the end portion 3p of the extension board 3 and the metal terminal 9 of the connector body 1p (insertion portion 1s) is maintained fixed. Other configurations and operational effects are the same as those of the above embodiment, and therefore, the description thereof is omitted.

Fig. 8 is a sectional view of an embedded structure 8 of modification 3. As shown in fig. 8, the fitting structure 8 of the present modification has a contour that can be fitted into the fitting portion (through hole) 3e of the extension substrate 3.
