Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of connectors, in particular to an intermediate connector. BACKGROUND

[0002] In the fields of power, communication and many industries, connectors are of great importance as they not only carry the task of current or signal transmission, but also directly relate to the stability and safety of the system. Traditional connector designs often focus on meeting the needs of a single type of connection, either force-bearing connection, mainly used in scenarios that need to bear large mechanical stress, or non-force-bearing connection, mainly focusing on electrical performance and signal transmission quality. However, with the continuous progress of technology and the diversification of engineering applications, the market has an urgent need for a connector that can meet the needs of both force-bearing and non-force-bearing connections. SUMMARY

[0003] The purpose of the present application is to provide a non-force-bearing intermediate connector that can meet the needs of both force-bearing and non-force-bearing connections.

[0004] To achieve the above purpose, the present application provides an intermediate connector, comprising:

[0005] An eccentric anti-falling wheel (1) connected with a center support (2) for providing guidance and anti-falling function when the wire is inserted;

[0006] A center support (2) for serving as a support structure of the intermediate connector;

[0007] A secondary anti-falling locking bolt (3) passing through the center support (2) and cooperating with the eccentric anti-falling wheel (1) for locking the wire after insertion;

[0008] A first connecting wire (4) and a second connecting wire (10) respectively connected with a conductive interface (11) for connecting electrical equipment;

[0009] An insulating shell (5);

[0010] A conductive interface mounting rack (6) fixed at both ends of the center support (2) for mounting the conductive interface (11);

[0011] A conductive interface tension spring (7) mounted on the conductive interface mounting rack (6) for maintaining the contact pressure of the conductive interface (11) with the wire;

[0012] An eccentric wheel spring mounting screw (8) mounted on the center support (2);

[0013] The eccentric tension spring (9) is sleeved on the eccentric spring mounting screw (8) and connected with the eccentric release freewheel (1) at one end, used to provide clamping force when the wire is inserted;

[0014] The same curvature arc surface conductive interface (11) is installed on the conductive interface mounting rack (6) and forms good contact with the wire.

[0015] Preferably, the conductive interface mounting rack (6) is connected with the center support (2) at both ends through screws, and four conductive interface mounting racks (6) are installed at each end.

[0016] Preferably, the eccentric release freewheel (1) is connected with the inside of the center support (2) through a fixing device, and two ends are symmetrically installed.

[0017] Preferably, the secondary anti-loose locking bolt (3) is matched with the inside of the center support (2) through threads, used to further lock the wire after the first connecting wire (4) or the second connecting wire (10) is installed to the predetermined position.

[0018] Preferably, the same curvature arc surface conductive interface (11) is connected with the conductive interface mounting rack (6) through the conductive interface tension spring (7), suitable for different specifications of wires.

[0019] Preferably, the insulating shell (5) is connected with the center support (2) through buckling or bonding.

[0020] The application has the following beneficial effects:

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

[0022] This unique design not only ensures that the wire can be quickly and barrier-free inserted into the connector, but also ingeniously uses the conical guide opening to guide and assist the positioning of the wire. Under the synergistic action of the eccentric wheel and the spring, the wire is tightly and firmly clamped, effectively preventing accidental falling of the wire. This design not only simplifies the installation process, but also greatly improves the efficiency and stability of the installation, truly realizing the goal of quick and reliable installation.

[0023] (2) Double insurance locking structure:

[0024] Based on the eccentric release mechanism, the application further introduces a bolt-driven locking mechanism, forming a double insurance locking structure. Through the tightening action of the threaded bolt, the wire is given additional clamping force, thereby realizing double protection. Even in high-strength 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 adaptive same curvature arc surface conductive interface:

[0026] The conductive interface in the present application adopts a unique cambered surface design, which can be widely adapted to wires with a size ranging from 35 to 240 square millimeters, which means that the same set of connector devices can meet the use requirements of wires with different diameters, without the need to replace different sizes of connectors. This feature not only improves the versatility and flexibility of the connector, but also reduces the maintenance cost and inventory pressure of the user, bringing great convenience and economic benefits to the user.

DETAILED DESCRIPTION

[0031] The detailed description of the drawings is intended as a description of the current embodiments of the present application, and is not intended to represent the only form in which the present application can be implemented. 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] Reference Figs. 1-2 The embodiment of the present application provides an intermediate connector, which comprises:

[0033] The eccentric anti-falling wheel 1 is connected with the center support 2, and is used to provide guiding and anti-falling functions when the wire is inserted;

[0034] The center support 2 is used as a support structure of the intermediate connector;

[0035] The secondary anti-falling locking bolt 3 passes through the center support 2 and cooperates with the eccentric anti-falling wheel 1, and is used to lock the wire after the wire is inserted;

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

[0037] The insulating shell 5;

[0038] The conductive interface mounting frame 6 is fixed at both ends of the center support 2, for mounting the conductive interface 11;

[0039] The conductive interface tension spring 7 is mounted on the conductive interface mounting frame 6, for maintaining the contact pressure of the conductive interface 11 with the wire;

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

[0041] The eccentric wheel tension spring 9 is sleeved on the eccentric wheel spring mounting screw 8, and one end is connected with the eccentric wheel 1, for providing clamping force when the wire is inserted;

[0042] The same curvature arc surface conductive interface 11 is mounted on the conductive interface mounting frame 6, and forms good contact with the wire.

[0043] Further, the conductive interface mounting frame 6 is connected with both ends of the center support 2 through screws, and four conductive interface mounting frames 6 are mounted at each end.

[0044] Further, the eccentric wheel 1 is connected with the inside of the center support 2 through a fixing device, and is symmetrically installed at both ends.

[0045] Further, the secondary anti-loose locking bolt 3 is matched with the inside of the center support 2 through threads, for further locking the wire after the first connecting wire 4 or the second connecting wire 10 is installed to the predetermined position.

[0046] Further, the same curvature arc surface conductive interface 11 is connected with the conductive interface mounting frame 6 through the conductive interface tension spring 7, and is suitable for wires of different specifications.

[0047] Further, the insulating shell 5 is connected with the center support 2 through buckling or bonding.

[0048] Specifically, referring to Figs. 1-2The center support 2 is provided with eight electrically-conductive interface mounting racks 6 (four at one end) at both ends, and four eccentric anti-falling wheels 1 (two at one end, symmetrically installed) are mounted inside the center support 2. The eccentric anti-falling wheels 1 are provided with anti-falling teeth. Four eccentric wheel spring mounting screws 8 are mounted on the center support 2, which are used to fix eccentric wheel tension springs 9, one end of which is connected with the eccentric anti-falling wheels 1. The electrically-conductive interface mounting racks 6 are provided with arc-surface electrically-conductive interfaces 11 of the same curvature at one end (one arc-surface electrically-conductive interface 11 is mounted on each electrically-conductive interface mounting rack 6, and four at one end together form a circle). The arc-surface electrically-conductive interfaces 11 are provided with electrically-conductive interface tension springs 7 at the tail, and the other end of the electrically-conductive interface tension springs 7 is mounted inside the electrically-conductive interface mounting rack 6. The electrically-conductive interface mounting rack 6 is provided with threads, and is provided with secondary anti-falling locking bolts 3, which can directly press the first connecting wire 4 or the second connecting wire 10 through the through holes on the center support 2.

[0049] In the implementation process, the first connecting wire 4 or the second connecting wire 10 is inserted into the connector through any one end of the connector. Under the guidance of the curved surface of the arc-surface electrically-conductive interface 11, the first connecting wire 4 or the second connecting wire 10 passes through the center position of the four-lobed arc-surface electrically-conductive interface 11, and the four-lobed arc-surface electrically-conductive interface 11 clamps the wire together under the action of the electrically-conductive interface tension spring 7 to ensure that the conductive amount of the wire reaches the design requirement. The wire continues to be inserted into the connector, and the wire pushes away the eccentric anti-falling wheel 1. The anti-falling teeth on the eccentric anti-falling wheel 1 tightly contact the wire under the action of the eccentric wheel tension spring 9. When the wire accidentally comes out, the eccentric anti-falling wheel 1 reversely rotates under the driving of the anti-falling teeth. Due to the eccentric design, the rotating radius is increased when the eccentric anti-falling wheel 1 reversely rotates, so as to reduce the rotating space and achieve the purpose of clamping the wire. After the first connecting wire 4 or the second connecting wire 10 is installed to the predetermined position, the secondary anti-falling locking bolt 3 is tightened to further lock the wire and achieve the purpose of secondary anti-loosening.

[0050] The above only discloses the preferred embodiments of the present application, and of course cannot limit the scope of the present application. Therefore, equivalent changes made according to the claims of the present application still fall within the scope of the present application.
