The present application is based on and claims priority from Japanese Patent Application No. 2022-118180 filed on Jul. 25, 2022, the disclosure of which is hereby incorporated by reference herein in its entirety.
The present invention relates to a connector with substrate.
A connector of a compression type pressed against and connected to a connection target object such as a substrate has been publicly known. The structure of the connector of this type is disclosed in, for example, Japanese Patent Application Laid-Open No. 2000-12123 (Patent Literature 1). The connector of the compression type of the related art disclosed in Patent Literature 1 described below is configured as an electric connector (1) including a contact (20) including an elastic spring section (23) as shown in
The contact (20) includes a substrate connecting section (22) solder-connected to a first circuit board (30) and a contact section (24) that is in contact with a second circuit board (40). The elastic spring section (23) having a spring property is provided between the substrate connecting section (22) and the contact section (24). The second circuit board (40) is pressed from the upward side of the contact (20) attached on the first circuit board (30) by solder-connection, whereby the elastic spring section (23) of the contact (20) exerts the spring property to generate a contact pressure between the second circuit board (40) and the contact (20). Note that reference numerals and signs concerning explanation of the related art document are distinguished from those in embodiments of the present invention by being parenthesized.
In the compression connector of the related art, screwing has been used for attachment (fixing) to the substrate.
However, when the compression connector is fixed to the substrate by the screwing, in general, a method of attaching nuts from a substrate surface on the opposite side of a connector mounting surface side on which the connector is mounted and tightening screws from the connector mounting surface side is adopted. In such a case of the related art, an operator needs to press the connector and the nuts with a hand or the like while tightening the screws. Thus, there is a problem that it is hard to do connector attaching (fixing) work. That is, since the nuts, which are separate components, are necessary besides the screws in a fixing structure for the compression connector and the substrate by the screwing of the related art, problems exist such as that the nuts are likely to be lost or work manhours increase.
That is, in the compression connector of the related art, it has been demanded to realize a configuration for performing secure attachment while improving workability of attachment in the attachment (fixing) to the substrate.
Accordingly, an object of the present invention is to realize a configuration with which, when a compression connector and a substrate are fixed, connector attaching (fixing) work is simple and the compression connector can be fixed to the substrate with a small motion.
A connector with substrate according to the present invention is a connector with substrate in which a connector of a compression type pressed against and connected to a connection target object and a substrate are attached, the connector with substrate including a compression connector including contacts that are in contact with the substrate, a housing to which the contacts are fixed, and a cover shell that covers an upper surface portion of the housing, wherein the cover shell includes a vertical surface vertically bent in a direction of the substrate from a top surface of the cover shell disposed in parallel to the substrate, and at least one or more fixing parts piercing through a hole formed in the substrate and functioning as slip-off prevention for the compression corrector with respect to the substrate are formed on the substrate side of the vertical surface.
That is, the connector with substrate according to the present invention includes a mechanism for attaching the connector of the compression type and the substrate. A simple and secure fixed state can be obtained by inserting the fixing part into the hole formed in the substrate.
In the connector with substrate according to the present invention, the fixing part can be formed to include: a flat base section formed to be connected to the substrate side of the vertical surface; an opening section connected to the substrate side of the base section and including an opening hole; and a flat distal end portion formed to be connected to the substrate side of the opening section.
Further, in the connector with substrate according to the present invention, the opening section can be formed to have a width dimension larger than the base section and the distal end portion to form the fixing part as a press-fit pin.
That is, when the fixing part is formed as the press-fit pin, the fixing part is compressed in the hole of the substrate, and the compression connector is held not to slip off in the vertical direction with respect to the substrate by a frictional force of the substrate and the hole.
Further, the connector with substrate according to the present invention can include a slip-stop pin inserted into the opening hole included in the opening section, and the slip-stop pin can include: a distal end portion bent when being inserted into the opening hole; an insertion section functioning as slip-off prevention for the compression connector with respect to the substrate by being inserted into the opening hole; and a flange section having a width dimension larger than a hole diameter of the opening hole.
That is, since the slip-stop pin is prevented from slipping off, after being inserted into the opening hole included in the opening section of the fixing part, by the distal end thereof being bent, the slip-stop pin is not dropped or lost unlike the screws and the nuts of the related art. Since the connector with substrate contains a mechanism for fixing the compression connector with a pin shape of the slip-stop pin, unlike with the related art, work manhours involving attachment are reduced and torque management for the screws is unnecessary.
Further, in the connector with substrate according to the present invention, the compression connector can include a bottom shell that covers a lower surface portion of the housing.
According to the present invention, it is possible to realize a structure in which, when the compression connector and the substrate are fixed, connector attaching (fixing) work is easy and the compression connector can be fixed to the substrate with a small motion. Therefore, according to the present invention, it is possible to perform secure attachment while improving workability of attachment (fixing) of the compression connector to the substrate.

On the other hand, a rear end portion 32b of the contact 32 has a linear shape extending straight. As shown in
Note that, concerning the members configuring the compression connector 31 in the first embodiment, the plurality of contacts 32 are made of a conductive metal material and the housing 33 that fixes the plurality of contacts 32 is made of a nonconductive resin material or the like. The cover shell 34 that covers the upper surface portion of the housing 33 and the bottom shell 35 that covers the lower surface portion of the housing 33 are combined, in a state in which the housing 33 is included between the cover shell 34 and the bottom shell 35, in the up-down direction to form an outline shape of the compression connector 31. The cover shell 34 and the bottom shell 35 protect the housing 33, in which the plurality of contacts 32 that receive energization from the electric cable 36 are embedded, by being disposed to enclose the outer circumference of the housing 33 in which the plurality of contacts 32 are embedded.

For example, the number of the press-fit pins 37 only has to be one or more. The disposition positions of the press-fit pins 37 can be arranged in any positions considering the shapes and the like of the compression connector 31 and the substrate 11.
