Description

Technical Field

[0001] This utility model relates to the field of electrical connection device technology, and specifically to a novel spring terminal for electrical applications. Background Technology

[0002] Spring terminal type electrical connectors are widely used in the electrical field. For example, patent document CN208571045U discloses an electrical connector in which a screw is installed in the socket mechanism and a screw hole is formed in the plug mechanism to cooperate with the screw. When the socket mechanism and the plug mechanism are connected, the screw is screwed into the screw hole to fix the two. However, there is no other fixing mechanism for the wires and other mechanisms inserted into the socket mechanism, which leads to unstable connection between the wires and the socket mechanism and needs to be improved. Utility Model Content

[0003] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:

[0004] This application discloses a novel spring terminal for electrical applications, comprising a plug mechanism and a socket mechanism for interlocking. In the socket mechanism, protrusions are provided on both sides of a base, and screws are connected to the protrusions. In the plug mechanism, threaded holes are provided on corresponding positions on both sides of a base, engaging with the screw threads. After the plug mechanism and socket mechanism are plugged in, they are fixed by screws threaded into the threaded holes. The device also includes grippers, with a connecting groove at the tail end of each gripper. The grippers are fitted onto the protrusions via the connecting groove and are horizontally rotatably hinged to the protrusions. A latching mechanism is provided between the groove wall and the side of the protrusion. When the grippers on both sides of the base rotate to face each other, the connecting groove and the corresponding side of the protrusion are latched together by the latching mechanism. In this state, the head of the gripper extends beyond the end of the base.

[0005] This solution adds a clamp. After the external wire or other wiring mechanism is connected to the socket mechanism, the clamp can hold the wire or other wiring mechanism connected to the socket mechanism. The snap-fit ​​mechanism can fix the clamp in the required position, which helps to hold the wire and other mechanism connected to the socket mechanism and improves the stability of the connection.

[0006] For snap-fit ​​mechanisms, such as common protrusions and grooves into which the protrusions are inserted, protrusions or grooves are formed on the walls of the connecting groove, and corresponding grooves or protrusions are formed on the sides of the protrusions.

[0007] Furthermore, the buckling mechanism includes a protrusion and a groove, wherein the protrusion is provided on the groove wall of the connecting groove and the side of the protrusion is provided with a groove for the protrusion to be engaged.

[0008] Furthermore, the gripper includes a body with a connecting groove formed at its tail end. A pivot portion is provided on the groove wall, allowing the pivot portion to hinge to the side of the protrusion. A protrusion is provided on one side of the pivot portion. The pivot portion can be a pivot shaft or a pivot hole. The body can be a common strip shape, or other configurations can be adopted, which will not be elaborated further. The configuration of the connecting groove at the tail end of the body facilitates docking with the protrusion and reduces the impact on the subsequent docking of the plug mechanism and socket mechanism.

[0009] Furthermore, the two grippers are provided with slots on the sides of the front end of the main body facing each other. These slots facilitate better fixing of wires that are connected to the socket mechanism, thereby improving stability.

[0010] Furthermore, the grippers are provided with holes for weight reduction, which helps to reduce weight, reduce material usage, and thus reduce costs.

[0011] Furthermore, the plug mechanism has a double row of pins on the second base, and the socket mechanism has a corresponding spring-type conductive mechanism on the first base that cooperates with the pins, which can better meet the wiring requirements.

[0012] Furthermore, the base includes a main body and a cover plate. The tail end of the main body is provided with an installation port that communicates with the cavity. The cover plate is provided at the installation port to close the installation port. The installation port facilitates the installation of the corresponding conductive mechanism into the cavity of the main body. The cover plate closes the installation port to reduce the influence of external factors.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model has clamps installed on both sides of the base in the socket mechanism, which can conveniently clamp and fix the wires and other components that are connected to the socket mechanism, thus helping to improve the stability of the connection. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] like Figure 1 , Figure 2 , Figure 3 As shown, in this example, a novel spring terminal for electrical applications includes a plug mechanism 2 and a socket mechanism 1 for interlocking. The socket mechanism 1 is a common type, with a conductive mechanism installed inside a base body and sockets at both ends corresponding to the conductive mechanism. The plug mechanism 2 is a common type, with a pin 22 installed on a base body 21. When the socket mechanism 1 and the plug mechanism 2 are connected, the end of the pin 22 is inserted into the socket to make an electrical connection with the conductive mechanism. Corresponding wires and other mechanisms can be connected to the conductive mechanism from the corresponding socket. The conductive mechanism is a common type, such as a spring clip.

[0024] In this example, the socket mechanism 1 includes a main body 10 and a cover plate 11. The end of the main body 10 has a mounting opening communicating with the cavity, which is closed by the cover plate 11. In this example, the main body 10 has protrusions 5 formed on opposite sides along its length. Screws 6 are connected to the protrusions 5, either threaded onto the protrusions 5 or with the screw end passing through a hole in the protrusion. Figure 2 As shown, screw 6 is positioned along the width of the main body 10. Screw holes 4 are formed at corresponding positions on both sides of the base 21 in the plug mechanism 2, engaging with the screw 6. After the plug mechanism 2 is inserted into the socket mechanism 1, the screw 6 and the screw holes 4 are threaded together, fixing the plug mechanism and the socket mechanism as one unit.

[0025] In this example, a gripper 3 is added, such as... Figure 1 , Figure 3As shown, the tail end of the gripper 3 is formed with a connecting groove 32. The gripper 3 is fitted onto the protrusion 5 through the connecting groove 32 and is horizontally rotatably hinged to the protrusion. The shape of the protrusion can be selected according to requirements, such as rectangular, trapezoidal, stepped, etc. The protrusion 5 can be integrally formed with the main body 10 of the base or formed independently and then fixed together. For the hinge structure, the gripper 3 includes a body 31. The body can be common, such as a strip shape, L-shaped, etc., or other configurations can be adopted, which will not be elaborated here. The tail end of the body 31 is formed with a connecting groove 32, and the groove wall of the connecting groove 32 is formed with a pivot part 34, such as a pivot or pivot hole. In this example, the pivot hole is used as the pivot part, and the pivot part 34 is hinged to the pivot 7 formed on the side of the protrusion 5.

[0026] In this example, a snap-fit ​​mechanism is added between the groove wall and the side of the protrusion in the connecting groove. When the jaws on both sides of the seat rotate to face each other, the connecting groove and the corresponding side of the protrusion are snapped together by the snap-fit ​​mechanism. In this state, the head of the jaws passes over the end of the seat. The snap-fit ​​mechanism is a common structure consisting of a protrusion and a groove for the protrusion to be engaged. For example, a protrusion or groove is formed on the groove wall of the connecting groove, and a corresponding groove or protrusion is formed on the side of the protrusion. Preferably, the snap-fit ​​mechanism includes a protrusion and a groove. A protrusion is formed outward on the groove wall of the connecting groove, and a groove for the protrusion to be engaged is formed on the side of the protrusion. Specifically, a protrusion 35 is formed outward on one side of the pivot 34, and a groove 8 for the protrusion to be engaged is formed on the side of the protrusion 5. When the jaws 3 on both sides of the seat rotate to face each other, as Figure 1 In the shown state, the tips of the two grippers 3 are facing each other, with the tips of the grippers 3 extending beyond the end of the base. At this time, the protrusion 35 on the gripper 3 engages with the groove 8, and the gripper is fixed. Force must be applied to the gripper to disengage the protrusion from the groove before the gripper can rotate. When a wire or other object is inserted into a socket in the base, the two grippers work together to hold the wire or other object in the middle, which helps improve stability. Regarding the position of the protrusion, as... Figure 3 As shown, a protrusion 35 is formed on the body below the pivot 34. Of course, the protrusion can also be selected according to the requirements.

[0027] To facilitate the clamping of wires and other components, in this example, the two grippers 3 have grooves 33 formed on the side of the front end of the main body facing each other. The grooves are arc-shaped, which allow for better connection of wires and other components to the socket mechanism. Holes 36 for weight reduction can also be formed on the grippers 3, such as one or more, which helps to reduce costs.

[0028] To meet wiring requirements, in this example, double rows of pins 22, such as 28 pins, are installed on the second base of the plug mechanism 2. Correspondingly, a spring-type conductive mechanism that mates with the pins is installed on the first base of the socket mechanism 1.

[0029] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
