However, this wiring method depends on flexible wires, which must have a large bending allowance; otherwise, wiring becomes difficult or even impossible, especially when the connector's installation position cannot be changed.

[0003] If rigid conductors (such as copper busbars) are used, and the length of the rigid conductors is exactly the preset wiring length after installation, then the conductors need to be stretched during actual wiring, the operation remains unchanged, and the conductors may become loose or break when exposed to vibration; if a longer slack conductor is reserved, wiring is convenient, but the conductors cannot straighten naturally after wiring, or cannot be routed according to the predetermined wiring path, resulting in bent sections that affect the aesthetics.

[0004] Therefore, this application proposes a retractable connector that facilitates wiring. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please see Figure 1-5 The present invention provides the following technical solution: a retractable connector, including an insulating shell 1, a main terminal 2 and a secondary terminal 3, wherein the insulating shell 1 is rectangular; the insulating shell 1 includes a base 11 and a housing 12, wherein the bottom end of the housing 12 is provided with a buckle 14 for the base 11 to be detachably connected, and the main terminal 2 is detachably connected to the housing 12 through a pin 5; The main terminal 2 is installed in the middle of the housing 12. The two auxiliary terminals 3 are U-shaped and engaged at both ends of the main terminal 2. The upper and lower end faces of the two auxiliary terminals 3 are provided with sliders 32. The housing 12 and the base 11 are provided with grooves 13 that can accommodate the sliders 32. The sliders 32 are slidably connected in the grooves 13. The sliding direction of the sliders 32 is the engagement direction of the auxiliary terminals 3 on the main terminal 2. Both secondary terminals 3 are provided with a first wiring port 31 in the sliding direction, and the sliding direction of the secondary terminals 3 is aligned with the wiring direction of the first wiring port 31; the housing 12 is provided with an opening 121 that exposes the side of the secondary terminals 3 near the first wiring port 31. The main terminal 2 and the auxiliary terminal 3 are provided with a first contact piece 4. The first contact piece 4 includes a first base plate 41 and a number of first spring pieces 42 that are elastically connected to the first base plate 41. The main terminal 2 or the auxiliary terminal 3 is provided with a first slot 21 that cooperates with both sides of the first base plate 41. Both ends of the first slot 21 penetrate the side wall of the main terminal 2 or the auxiliary terminal 3.

[0021] Usage and working principle: The first connection port 31 is a common threaded hole. When wiring, put the hole on the rigid wire (such as a copper busbar) onto the screw, and then screw the screw onto the first connection port 31 to connect the wire. After wiring and when the circuit is closed, electrons migrate from one end of the wire to a connected secondary terminal 3, and then from the secondary terminal 3 through the main terminal 2 to another secondary terminal 3, and then out through the other end of the wire.

[0022] As an optional implementation of this utility model, since the secondary terminal 3 can slide in the insulating shell 1 along the wiring direction, when wiring on the first wiring port 31, the secondary terminal 3 can be pulled out to allow the wire to have more length slack, which facilitates the wiring operation. Moreover, after wiring, the secondary terminal 3 can be retracted into the shell 12, so that the wire is in a tension-free straight state or in a tension-free distribution state according to the predetermined wiring path, which is more aesthetically pleasing. When encountering vibration in the usage environment, the sliding of the secondary terminal 3 can also adapt to the tension of the wire and extend or retract, thus avoiding the wire breakage.

[0023] Furthermore, the independent first springs 42 on the first contact piece 4 not only form an elastic contact between the main terminal 2 and the secondary terminal 3, which can buffer vibration, but also ensure that each independent spring is not affected by processing. When the secondary terminal 3 is engaged with the surface of the main terminal 2, a stable pressure contact can be formed, so that the current carrying performance is not affected. The first slot 21 facilitates the installation of the first contact piece 4. During installation, the first base plate 41 is simply inserted into the first slot 21 from the side. After installation, the first slot 21 and the housing 12 limit the movement, preventing the first contact piece 4 from detaching from the first slot 21.

[0024] This implementation method combines the convenience of installation and operation with the aesthetics of the finished product, and also has seismic resistance, making it less likely for rigid wires to break due to vibration.

[0025] Furthermore, the housing 12 is also provided with a second wiring port 122 at the edge of the opening 121, and the interior of the second wiring port 122 extends to the position of the main terminal 2. This allows for wiring using existing long, flexible wires. During wiring, the terminal of the wire is inserted into the second wiring port 122, and a screw is screwed into the screw hole 1221 on the housing 12 perpendicular to the depth direction of the second wiring port 122 (e.g., ...). Figure 4 As shown in the diagram, the screw is pressed into or passes through the terminal in the second connector 122 to secure the flexible wire. This makes this embodiment compatible with both flexible and rigid wire connections.

[0026] Furthermore, there are two main terminals 2, and each main terminal 2 is also provided with an interface 2223 for plug insertion. Each main terminal 2 has one interface 2223, or one interface 2223 is provided at the position where the two main terminals 2 face each other as in embodiment 2; alternatively, there may be only one main terminal 2, which does not have a switching function and is only used for wiring.

[0027] Example 2: Please see Figure 1-6 The present invention provides the following technical solution: a retractable connector, including an insulating shell 1, a main terminal 2 and a secondary terminal 3, wherein there are two main terminals 2 and the two main terminals 2 do not contact each other, and both main terminals 2 are fixedly connected to the insulating shell 1 by means of pins 5; Each of the two main terminals 2 has a protrusion 22 at one of its facing ends, and the two protrusions 22 are in the same direction. The insulating shell 1 has a fork-shaped part 123 that matches the two protrusions 22. The insulating shell 1 also has a partition between the two main terminals 2. The two protrusions 22 are slidably connected in the fork-shaped part 123. The top of the facing surfaces of the two protrusions 22 is provided with a second slot 221. Both ends of the second slot 221 penetrate the side wall of the protrusion 22. The second slot 221 is provided with a second contact piece 222. The second contact piece 222 includes a second base plate 2221 and a number of second spring pieces 2222 that are elastically connected to the second base plate 2221. The pop-out directions of the second spring pieces 2222 on the two second contact pieces 222 are opposite, and an interface 2223 for plug insertion is formed between the two second contact pieces 222. After the plug is inserted into the interface 2223, the two main terminals 2 are closed. Two secondary terminals 3 respectively contact the upper and / or lower surfaces of both ends of the main terminal 2, and both secondary terminals 3 are slidably connected in the insulating housing 1. Both secondary terminals 3 are provided with a first wiring port 31 in the sliding direction. The sliding direction of the secondary terminals 3 is aligned with the wiring direction of the first wiring port 31. The insulating housing 1 is provided with an opening 121 that exposes the side of the secondary terminal 3 near the first wiring port 31.

[0028] As an optional implementation of this utility model, compared with Embodiment 1, this embodiment further defines the design of interface 2223 as an electrical connector with a switching function. During wiring or maintenance, the connector can be disconnected by removing the plug, ensuring the safety of the operator.

[0029] The plug is a sheet-like conductor. When it is inserted into the interface 2223, because the second springs 2222 on the second contact piece 222 are also independent of each other, a stable pressure contact can be formed, and there will be no high or low pin phenomenon, ensuring a stable electrical connection. Furthermore, this structure does not have such high requirements for precision and raw materials, so it is easy to process and the manufacturing cost will not be too high.

[0030] Furthermore, the outer surface of the fork-shaped part 123 is also provided with a shielding plate 6, which is made of existing metal material and is generally used to shield the influence of the surrounding magnetic field on the transmission of internal electrical signals.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
