Technical Field

[0001] The present invention relates to the technical field of electrical connectors, and in particular to an electrical connection device and a contact arrangement method. Background Art

[0002] The connector is a component that electronic engineering technicians often come into contact with. It builds a bridge of communication between blocked or isolated circuits within a circuit, thereby allowing current to flow and enabling the circuit to achieve its intended function. There are many types of existing connectors, among which the most common connector is the contact connector. Most of the existing contact connectors are plugged together, and the connector is connected by a snap-on connection. When connected, the snap head is deformed and stuck in the snap-on position, which is more convenient. When the connector is separated, two hands are required to pull the connector apart in two directions. During this process, the snap-on is deformed and leaves the snap-on position.

[0003] However, the existing electrical connection devices have the following disadvantages: In actual use, the existing connectors are prone to the problem of difficult to identify connection direction, which increases the difficulty of plugging and unplugging. In addition, they do not have waterproof and dustproof functions, which affects the normal use of the equipment. Summary of the invention

[0004] The purpose of the present invention is to provide an electrical connection device and a contact arrangement method to solve the problem that the existing connector proposed in the above background technology is easy to be difficult to identify the connection direction during actual use, which increases the difficulty of plugging and unplugging, and has no waterproof and dustproof functions, affecting the normal use of the equipment.

[0005] To achieve the above object, the present invention provides the following technical solutions: An electrical connection device includes a first connection part and a second connection part, wherein a plurality of spring contacts are embedded and installed in the middle of one end of the first connection part, a plurality of contact posts are embedded and installed in the middle of one end of the second connection part, a convex limiting protection component is embedded and installed on the outer side of one end of the second connection part, the convex limiting protection component surrounds the spring contact, a concave limiting protection component is embedded and installed on one side of the first connection part, and the inner side of the concave limiting protection component is plugged into the outer side of the convex limiting protection component.

[0006] Preferably, a plurality of the contact posts are arranged in a double layer, and a plurality of the spring contacts are arranged in an "L" shape.

[0009] Preferably, the positions of the spring contact and the contact post are interchangeable.

[0010] Preferably, the convex position-limiting protection component and the concave position-limiting protection component are both detachable components.

[0011] Preferably, the convex limiting protection component and the concave limiting protection component are made of hydrophobic soft material.

[0012] In another aspect, the present invention provides a contact arrangement method for an electrical connection device, comprising the following steps: S1, contact column arrangement, determining the spatial structure of the double-layer arrangement of the contact columns, taking the installation plane in the middle of one end of the first connecting portion as a reference, the upper and lower layers of contact columns are parallel to each other and perpendicular to the installation plane; S2, spring contact arrangement, replicates the double-layer arrangement of the contact posts and is used to arrange the spring contacts to form a double-layer arrangement of the spring contacts. The upper spring contacts are then rotated 90 or 270 degrees around the center to form an "L" shaped arrangement of the spring contacts.
