Abstract

In a connector with substrate, a compression connector pressed against and connected to a connection target object and a substrate are attached.

Description

CROSS-REFERENCE TO RELATED APPLICATION The present application is based on and claims priority from Japanese Patent Application No. 2022-118182 filed on Jul. 25, 2022, the disclosure of which is hereby incorporated by reference herein in its entirety. BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a connector with substrate. Description of the Related Art 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 FIG. 31. In the electric connector (1), a plurality of contacts (20) are disposed in an arrayed state. 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 the case of the related art, since a provisional holding mechanism for provisionally holding the connector on the substrate is absent, an operator needs to press the connector and the nuts by hand or the like while tightening the screws and, therefore, there is a problem that it is hard to perform 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. In the related art, since the compression connector and the substrate are not provisionally held when the screwing is performed, positions of the compression connector and the substrate are not determined because of repulsion with the substrate by the contact. It is necessary to press the compression connector to the substrate side with a hand or a jig when the screwing is performed. In other words, 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, by proposing a configuration that, when fixing a compression connector and a substrate, can realize a state in which the compression connector is provisionally held on the substrate and, thereafter, perform regular connection such as screwing, realize a configuration for performing secure attachment while improving workability of attachment (fixing) of the compression connector to the substrate. SUMMARY OF THE INVENTION A connector with substrate according to the present invention is a connector with substrate in which a compression connector pressed against and connected to a connection target object and a substrate are attached, the 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, the connector with substrate including: a provisional holding mechanism that provisionally holds the compression connector on the substrate; and a regular connection mechanism that, after the compression connector is provisionally held on the substrate by the provisional holding mechanism, regularly connects the compression connector to the substrate. That is, the connector with substrate according to the present invention includes the regular connection mechanism that attaches the compression connector and the substrate using screws and further includes the provisional holding me
