Description

Technical field:

[0001] The utility model relates to the technical field of connectors, and more specifically to a connector with multiple wiring schemes. Background technology:

[0002] Connector, used for electrical connection. Figure 1 As shown, it is an existing conventional spring-type connector, which consists of a plastic body 91 and an internal conductive terminal 92 and a spring 93. One end of the conductive terminal is exposed from the plastic body, and the other end forms a clamping structure with the spring for connecting the wire inserted into the connector.

[0003] Figure 2 As shown, it is a screw lock connector, which adopts a combination of a screw 81 and a spring 82. A pressure plate 84 is provided on the screw. By turning the screw, the end of the wire is clamped between the conductive terminal 83 and the pressure plate 84. Utility model content:

[0004] The technical problem solved by the utility model is that the connector in the prior art adopts a single spring-type connection or a locking screw connection.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a connector, including a plastic body, a conductive terminal built into the plastic body, a first socket and a second socket are provided on the plastic body, one end of the conductive terminal is equipped with a spring sheet, the spring sheet is located next to the first socket, and the other end of the conductive terminal is equipped with a locking screw structure, the locking screw structure is located next to the second socket.

[0006] The first wire is inserted into the first jack, and the first wire acts on the spring sheet, causing the spring sheet to accumulate elastic potential energy, and the spring sheet acts on the first wire to press it against the conductive terminal. The second wire is inserted into the second jack and extends into the locking screw structure. The operator fixes the second wire by screwing the screw, so that the second wire is in close contact with the conductive terminal. In this way, the first wire is electrically connected to the second wire through the conductive terminal.

[0007] As an option, the first plug hole and the second plug hole are respectively arranged above and below the plastic body, that is, the first plug hole is an upper plug hole and the second plug hole is a lower plug hole.

[0008] A slot structure shaped like the conductive terminal is arranged in the plastic body, and the conductive terminal is engaged in the slot structure to achieve positioning.

[0009] The upper part of the conductive terminal is bent, and a middle through slot is provided on the bent structure. The wire inserted into the first plug hole passes through the middle through slot, and one end of the spring sheet abuts against one side of the middle through slot, and the other end of the spring sheet can press the wire tightly against the conductive terminal. Before the first wire passes through the middle through slot, the spring sheet acts on the spring sheet, so that the spring sheet accumulates elastic potential energy. After the first wire passes through the middle through slot, the elastic potential energy causes the spring sheet to press the first wire tightly against the conductive terminal.

[0010] As a structural option, the spring piece is U-shaped, and an arc-shaped spring piece positioning structure is provided in the plastic body. The arc-shaped portion of the spring piece fits in the spring piece positioning structure to achieve positioning of the spring piece in the plastic body.

[0011] The screw locking structure includes an adjusting screw and a screw pressing plate matched with the adjusting screw. A screw connection through hole is provided at the lower part of the conductive terminal. The wire inserted into the second jack extends between the screw pressing plate and the conductive terminal. The adjusting screw matched with the screw connection through hole can drive the screw pressing plate to clamp the wire. A bolt adjustment through hole is provided on the plastic body. The operator's screwdriver can extend into the bolt adjustment through hole to turn the adjusting screw. The adjusting screw drives the screw pressing plate to approach the conductive terminal to clamp the second wire.

[0012] The screw pressure plate is provided with a bending rod, the conductive terminal is provided with a guide hole matched with the bending rod, the bending rod is sleeved with a clamping spring, and the clamping spring is located between the screw pressure plate and the conductive terminal. The screw pressure plate clamps the second conductor, and the clamping spring accumulates elastic potential energy, which acts on the screw pressure plate, can prevent the screw pressure plate and the adjusting screw from loosening, and is conducive to the stable connection of the second conductor.

[0013] An extension pointing to the screw pressure plate is formed on the side wall of the inner cavity of the plastic body. When the operator loosens the adjusting screw, the adjusting screw is disengaged from the screw connection through hole, the elastic potential energy of the compression spring is released, and the screw pressure plate is pressed toward the extension, which limits the screw pressure plate. When the operator tightens the adjusting screw, the adjusting screw can accurately match the screw connection through hole under the guidance of the bending rod and the guide hole.

[0014] The outstanding effect of the utility model is that it can not only meet the requirements of spring-type connection but also can be connected by using a connection method of an adjusting screw and a compression spring, thus meeting the needs of users for different connection methods and having a wide range of applications.
