Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to an intermediate connector. Background Art

[0002] In power, communications and many industrial fields, the application of connectors is crucial. They not only carry the task of transmitting current or signals, but are also directly related to the stability and safety of the system. Traditional connector designs often focus on meeting a single type of connection requirements, that is, either a load-bearing connection, which is mainly used in scenarios that need to withstand greater mechanical stress; or a non-load-bearing connection, which mainly focuses on electrical performance and signal transmission quality. However, with the continuous advancement of technology and the diversification of engineering applications, the market has put forward an urgent demand for a connector that can meet both load-bearing and non-load-bearing connection requirements. Summary of the invention

[0003] The object of the present invention is to provide a non-load-bearing intermediate connector, which can meet the requirements of both load-bearing and non-load-bearing connection.

[0004] To achieve the above object, the present invention provides an intermediate connector, comprising:

[0005] An eccentric anti-drop wheel (1) is connected to the central support (2) and is used to provide a guiding and anti-drop function when the wire is inserted;

[0006] A central support (2), used as a supporting structure for the intermediate connector;

[0007] A secondary anti-drop locking bolt (3) passes through the central bracket (2) and cooperates with the eccentric anti-drop wheel (1) to lock the wire after the wire is inserted;

[0008] A first connecting wire (4) and a second connecting wire (10) are respectively connected to the conductive interface (11) and are used to connect electrical equipment;

[0009] Insulating housing (5);

[0010] Conductive interface mounting frames (6), fixed at both ends of the central support (2), and used for mounting the conductive interface (11);

[0011] A conductive interface tensioning spring (7), mounted on the conductive interface mounting frame (6), and used to maintain the contact pressure between the conductive interface (11) and the conductor;

[0012] The eccentric wheel spring mounting screw (8) is mounted on the center bracket (2);

[0013] An eccentric wheel tensioning spring (9) is sleeved on the eccentric wheel spring mounting screw (8), and one end of the eccentric wheel tensioning spring is connected to the eccentric wheel anti-dropping wheel (1), and is used to provide a clamping force when the wire is inserted;

[0014] The conductive interface (11) with the same curvature arc surface is mounted on the conductive interface mounting frame (6) to form good contact with the conductive wire.

[0015] Preferably, the conductive interface mounting frame (6) is connected to both ends of the central support (2) by means of screws, and four conductive interface mounting frames (6) are installed at each end.

[0016] Preferably, the eccentric anti-slip wheel (1) is connected to the inside of the central support (2) through a fixing device, and two are provided at one end and are installed symmetrically on the left and right.

[0017] Preferably, the secondary anti-drop locking bolt (3) cooperates with the interior of the central bracket (2) through threads, and is used to further lock the wire after the first connecting wire (4) or the second connecting wire (10) is installed to a predetermined position.

[0018] Preferably, the conductive interface (11) with the same curvature arc surface is connected to the conductive interface mounting frame (6) via a conductive interface tensioning spring (7) to accommodate wires of different specifications.

[0019] Preferably, the insulating shell (5) is connected to the central support (2) by means of snap-fitting or bonding.

[0020] The present invention has the following beneficial effects:

[0021] (1) Innovative conical eccentric shape design:

[0022] This unique design not only ensures that the line can be quickly and unimpededly inserted into the connector, but also cleverly uses the tapered guide port to guide and assist in the positioning of the line. With the coordinated action of the eccentric wheel and the spring, the wire is tightly and firmly clamped, effectively preventing the wire from accidentally falling off. This design not only simplifies the installation process, but also greatly improves the efficiency and stability of the installation, truly achieving the goal of fast and reliable installation.

[0023] (2) Double insurance locking structure:

[0024] Based on the eccentric release mechanism, the present invention further introduces a bolt-driven locking mechanism to form a double-safety locking structure. Through the tightening action of the threaded bolt, the wire obtains additional clamping force, thereby achieving double protection. Even in high-intensity or harsh environments, the wire can be effectively prevented from loosening. This design not only enhances the safety of the connector, but also improves its durability and reliability.

[0025] (3) Highly adaptable conductive interface with the same curvature:

[0026] The conductive interface in the present invention adopts a unique arc surface design with the same curvature, which enables it to be widely adapted to wires within the specification range of 35 to 240 square millimeters. This means that the same set of connector devices can meet the use requirements of wires with a variety of different wire diameters without the need to replace connectors of different specifications. This feature not only improves the versatility and flexibility of the connector, but also reduces the user's maintenance costs and inventory pressure, bringing great convenience and economic benefits to the user.

It should be understood that the same or equivalent functions can be accomplished by different embodiments intended to be included in the spirit and scope of the present application.

[0032] See also Figure 1-2 , an embodiment of the present invention provides an intermediate connector, comprising:

[0033] The eccentric anti-drop wheel 1 is connected to the central bracket 2 and is used to provide a guiding and anti-drop function when the wire is inserted;

[0034] A central support 2, used as a supporting structure for the intermediate connector;

[0035] The secondary anti-dropping locking bolt 3 passes through the central bracket 2 and cooperates with the eccentric anti-dropping wheel 1 to lock the wire after the wire is inserted;

[0036] The first connecting wire 4 and the second connecting wire 10 are respectively connected to the conductive interface 11 for connecting the electrical device;

[0037] Insulating housing 5;

[0038] Conductive interface mounting brackets 6 are fixed at both ends of the central bracket 2 and are used to mount the conductive interface 11;

[0039] A conductive interface tensioning spring 7, mounted on the conductive interface mounting frame 6, for maintaining the contact pressure between the conductive interface 11 and the wire;

[0040] The eccentric wheel spring mounting screw 8 is mounted on the center bracket 2;

[0041] The eccentric wheel tensioning spring 9 is sleeved on the eccentric wheel spring mounting screw 8, and one end is connected to the eccentric wheel anti-dropping wheel 1, and is used to provide clamping force when the wire is inserted;

[0042] The conductive interface 11 with the same curvature arc surface is installed on the conductive interface mounting frame 6 to form a good contact with the wire.

[0043] Furthermore, the conductive interface mounting brackets 6 are connected to both ends of the central bracket 2 by screws, and four conductive interface mounting brackets 6 are installed at each end.

[0044] Furthermore, the eccentric anti-slip wheel 1 is connected to the inside of the central bracket 2 through a fixing device, and two are provided at one end and are installed symmetrically on the left and right.

[0045] Furthermore, the secondary anti-drop locking bolt 3 cooperates with the interior of the central bracket 2 through threads, and is used to further lock the wire after the first connecting wire 4 or the second connecting wire 10 is installed to a predetermined position.

[0046] Furthermore, the conductive interface 11 with the same curvature arc surface is connected to the conductive interface mounting frame 6 through the conductive interface tensioning spring 7 to adapt to wires of different specifications.

[0047] Furthermore, the insulating shell 5 is connected to the central bracket 2 by snapping or bonding.

[0048] Specifically, see Figure 1-2, eight conductive interface mounting frames 6 (four at one end) are respectively installed at both ends of the center bracket 2, and four eccentric anti-slip wheels 1 (two at one end, symmetrically installed on the left and right) are installed inside the center bracket 2. Anti-slip teeth are processed on the eccentric anti-slip wheels 1, and four eccentric wheel spring mounting screws 8 are installed on the center bracket 2. The eccentric wheel spring mounting screws 8 are used to fix the eccentric wheel tensioning spring 9, and one end of the eccentric wheel tensioning spring 9 is connected to the eccentric anti-slip wheel 1; a conductive interface mounting frame 6 is installed with a same-curvature arc surface conductive interface 11 at one end (each conductive interface mounting frame 6 is installed with a same-curvature arc surface conductive interface 11, and the four at one end together form a circle) A conductive interface tensioning spring 7 is installed at the tail of the same-curvature arc surface conductive interface 11, and the other end of the conductive interface tensioning spring 7 is installed inside the conductive interface mounting frame 6; the conductive interface mounting frame 6 is threaded and is equipped with a secondary anti-slip locking bolt 3, which can pass through the through hole on the center bracket 2 to directly press the first connecting wire 4 or the second connecting wire 10.

[0049] During the implementation process, the first connecting wire 4 or the second connecting wire 10 is inserted into the connector through any end of the connector. Under the guidance of the curved surface of the conductive interface 11 with the same curvature, the first connecting wire 4 or the second connecting wire 10 passes through the center position of the four-petal conductive interface 11 with the same curvature. Under the action of the conductive interface tensioning spring 7, the four-petal conductive interface 11 with the same curvature clamps the wire together to ensure that the conductivity of the wire meets the design requirements; the wire continues to be inserted into the connector, and the wire pushes the eccentric release anti-slip wheel 1. Under the action of the eccentric wheel tensioning spring 9, the anti-slip teeth on the eccentric release anti-slip wheel 1 are in close contact with the wire; when the wire accidentally slips out, the eccentric release anti-slip wheel 1 rotates in the opposite direction under the drive of the anti-slip teeth. Due to its eccentric design, when the eccentric release anti-slip wheel 1 rotates in the opposite direction, the rotation radius will be increased, thereby reducing its rotation space, so as to achieve the purpose of clamping the wire. When the first connecting wire 4 or the second connecting wire 10 is installed to the predetermined position, tighten the secondary anti-slip locking bolt 3 to further lock the wire to achieve the purpose of secondary anti-loosening.

[0050] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
