Description
Technical Field
The invention relates to the technical field of conductive connection, in particular to a contact element for a connector between parallel plates.
Background
In the field of conductive connection, a connector between parallel boards is often used to connect two other connectors, and generally, a connector between parallel boards includes a substrate, a mounting hole is formed in the substrate, and a contact is mounted in the mounting hole and is used for being conductively connected with a corresponding contact on two mating connectors. For example, patent document CN104518318B discloses a bow-shaped elastic contact spring, which is mounted on a substrate to form a connector between parallel plates.
With the above-mentioned parallel board-to-board connector including the spring contact spring having the similar bow shape, when the distance between the two mating connectors is changed, the size of the contact in the corresponding parallel board-to-board connector in the thickness direction of the substrate needs to be adjusted, which makes the parallel board-to-board connector of this structure need to be redesigned and manufactured for the connectors to be connected in different situations, and the cost is high.
Disclosure of Invention
The invention aims to provide a contact for a parallel board-to-board connector, which is used for a low-cost parallel board-to-board connector.
In order to achieve the purpose, the contact piece for the parallel plate-to-plate connector provided by the invention adopts the following technical scheme:
the contact piece for the parallel board-to-board connector comprises a connecting section and an elastic abutting section, wherein the connecting section is used for being fixedly connected with a metalized hole of a substrate and conducting electricity between the connecting section and the metalized hole, and the elastic abutting section at least partially exposes out of the metalized hole and elastically abuts against the adaptive contact piece when in use.
The connector between the parallel plates provided by the invention has the beneficial effects that: the contact piece for the parallel inter-board connector can be used for being installed in a metalized hole of a parallel inter-board connector substrate, two ends of each metalized hole are respectively installed, the two contact pieces are electrically conducted through the metalized holes, and for adaptive connectors with different spacing distances, the thickness of the substrate can be changed to enable the parallel inter-board connector to be connected with the corresponding adaptive connector without redesigning and manufacturing a new contact piece, so that the overall design and manufacturing cost of the parallel inter-board connector is low.
Furthermore, the elastic abutting section is of a sheet structure, and through holes are punched on the elastic abutting section to form an annular structure capable of elastic deformation. The annular structure formed in this way can provide a larger positive pressure to the contact on the adapter connector, thereby weakening the vibration of the adapter connector and the parallel plate-to-plate connector as a whole; in addition, the elastic abutting section is of a sheet structure, so that the space occupied by the elastic abutting section can be reduced, and the density of the contact elements arranged on the parallel inter-board connector using the contact elements can be improved.
Further, the ring-shaped structure is shaped as a heart, the tip of the heart-shaped ring-shaped structure facing away from the connecting section and being in contact with the mating contact member in use. This form of resilient abutment section can provide sufficient positive pressure to the contacts on the mating connector with good structural stability.
Furthermore, the contact piece for the parallel plate-to-plate connector is of a sheet structure. With the arrangement, the space occupied by the contact is smaller, the size of the metalized hole on the connector substrate between the parallel boards can also be smaller, more metalized holes can be arranged on the connector substrate between the parallel boards, and the density of the contact arranged on the connector between the parallel boards can be improved.
Further, the connecting section and the elastic abutting section are integrally arranged. The arrangement can simplify the manufacturing process of the contact and save the connecting process of the connecting section and the elastic abutting section.
Further, linkage segment and the integrative setting of elasticity butt section, the linkage segment is lamellar structure, linkage segment and elasticity butt section coplane. The connecting section and the elastic abutting section are integrally arranged, so that the manufacturing process of the contact element can be simplified, and the connecting process of the connecting section and the elastic abutting section is saved; the connecting section is of a sheet structure and is coplanar with the elastic abutting section, so that the whole occupied space of the contact is smaller, the size of the metalized hole in the connector substrate between the parallel plates can be smaller, more metalized holes can be formed in the connector substrate between the parallel plates, and the density of the contact arranged on the connector between the parallel plates can be improved.
Furthermore, a convex structure is arranged on the connecting section, and the connecting section is in interference fit with the hole wall of the metalized hole through the convex structure when being installed in the metalized hole. The interference fit ensures the full contact between the connecting section and the metallized hole, thereby ensuring the connection reliability of the connector between the parallel plates.
Furthermore, the connecting section is provided with a containing hole for containing soldering paste required when the contact is welded with the metalized hole through reflow soldering. The arrangement is matched with the process requirement, so that the connector is more convenient to manufacture.
Further, the width of the elastic abutting section is larger than that of the connecting section. By the arrangement, the contact piece can be prevented from moving into the metalized hole when being abutted and pressed with the adaptive connector, so that the contact between the connector between the parallel boards and the adaptive connector is insufficient; in addition, the depth of the contact extending into the metalized hole is limited, and the situation that the part of the contact extending into the metalized hole is too long or too short to influence the normal use of the parallel board-to-board connector is prevented.
