Description

Technical Field

[0001] The invention relates to the technical field of connectors, and in particular to a conductive connector for energy equipment. Background Art

[0002] Connectors are indispensable components in electronic devices. Their function is to build a bridge of communication between blocked or isolated circuits within a circuit, thereby allowing current to flow and the circuit to achieve its intended function.

[0003] With the differences in application objects, frequencies, powers, application environments, etc., various connectors have been born. For example, a Chinese reference document with authorization announcement number CN219717280U discloses a straight-through terminal that is easy to install. When using the straight-through terminal that is easy to install, first align the wire with the plug-in hole, and then insert the wire until it contacts the clamping block. As the wire is further inserted, the clamping block will be elastically deformed away from the wire by external pressure so that the wire can be plugged into place. When the wire is plugged into place, the external force applied to the wire is removed. At this time, the clamping block will be squeezed and fit against the surface of the wire under the action of its own elastic force, and the wire will be limited and fixed; at the same time, the anti-slip ring will be squeezed against the outer surface of the wire, further enhancing the tight pressure between the plug-in hole and the wire, and ensuring the stability of the wire fixed on the wiring piece.

[0004] However, after long-term use, the existing connectors are prone to falling off and breaking contact due to internal factors or external factors, resulting in poor contact between the electrical connector and the docking connector, affecting the normal transmission of signals. Summary of the invention

[0005] Based on this, it is necessary to provide a conductive connector for energy equipment to address the problem of unstable signal transmission in current connectors.

[0010] Furthermore, the first clamping portion includes a plurality of first clamps arranged along the circumferential direction, one end of the first clamp is elastically hinged on the terminal, and the other end is suspended; when the plurality of first clamps clamp the wire, the suspended ends thereof tend to move closer to each other.

[0014] Furthermore, the conductive connector of the energy device also includes a rotating part, and the rotating part is configured to drive the terminal to rotate so as to twist and gather the exposed part of the wire.

[0015] Furthermore, the rotating part includes two spiral holes and two spiral pieces, the two spiral holes and the two slots are arranged in a one-to-one correspondence, and are all opened on the side wall surfaces of the slots; the two spiral pieces and the two terminals are arranged in a one-to-one correspondence, and are all spirally wound on the outer peripheral walls of the terminals. When in use, the spiral pieces are inserted into the spiral holes, and the matching direction between the spiral holes and the spiral holes is spiral matching.

[0016] Furthermore, the two slots are symmetrically arranged; and the spiral holes in the two slots have opposite rotation directions.

[0017] Furthermore, a puncture portion is provided on a side of the second clip facing the wire, and the puncture portion is configured to partially penetrate or pierce the insulation of the wire.

[0018] Furthermore, the puncture portion is configured as a cone-shaped structure.

[0019] The beneficial effects of the present invention are:

[0021] Furthermore, by providing a rotating part, during use, the rotating part drives the terminal to rotate, and the terminal synchronously drives the first clamping part to rotate, so as to twist and gather the exposed part of the wire, while making the exposed part of the wire contact more closely, and maintaining the contact between the wire and the first clamping part in a rotational manner, which helps to improve the stability of the electrical connection between the wire and the first clamping part.

[0033] like Figures 1 to 5 As shown, the conductive connector of the energy device provided by the present invention is used for electrically connecting the wires. In this embodiment, the conductive connector of the energy device is configured to include a shell 1 and two terminals 2. Specifically, the shell 1 is configured to be a box structure, and a strip-shaped mounting hole is opened through the side wall surface of the shell 1. The mounting hole extends along the length direction of the shell 1, and a strip-shaped conductive sheet 13 is inserted in the mounting hole; more specifically, the conductive sheet 13 is configured to be made of a conductive material, such as copper, silver, aluminum, etc.; the two terminals 2 are both inserted in the shell 1 and are electrically connected. Specifically, as shown in FIG. Figure 2 and Figure 3 As shown, the terminal 2 is configured as a ring structure; each terminal 2 is provided with a first clamping portion and a second clamping portion, and the first clamping portion is configured to be able to elastically clamp the wire and be able to be electrically connected to the wire.

[0034] It is understandable that the housing 1 can be made of a transparent material, such as plastic, glass, etc., so that the connection between the wire and the connector can be observed at any time.

[0035] In this embodiment, the first clamping portion is configured to include a plurality of first clamping pieces 21 arranged along the circumferential direction, one end of the first clamping piece 21 is elastically hinged on the terminal 2, and the other end is suspended. Specifically, Figure 2 As shown, the right end of the first clamp 21 is elastically hinged on the left end face of the terminal 2 when installed, and the left end is suspended; more specifically, in order to facilitate the provision of a driving force for the elastic rotation of the first clamp 21, the first clamping portion is configured to also include a torsion spring whose number is equal to the number of the first clamps 21, and the torsion springs and the first clamps 21 are arranged in a one-to-one correspondence, and when installed, one end is fixedly connected to the left end face of the terminal 2, and the other end is fixedly connected to the first clamp 21; when the multiple first clamps 21 clamp the wire, the suspended ends thereof have a tendency to move closer to each other, and specifically, under the action of the torsion springs, the first clamp 21 has a tendency to swing toward the axial direction close to the terminal 2, so as to clamp the wire; for example, the number of the first clamps 21 can be set to four, and they are arranged circumferentially on the left end face of the terminal 2.

[0036] It is understandable that the plurality of first clamping pieces 21 may be arranged evenly along the circumferential direction, so as to improve the stability of the first clamping portion when clamping the wire by balancing the force on the wire when clamping the wire.

[0037] The second clamping portion is configured to rigidly clamp the conductor.

[0038] In this embodiment, two slots 11 are provided inside the housing 1, and the two terminals 2 and the two slots 11 are provided in a one-to-one correspondence. A guide surface is provided inside the slot 11. Specifically, Figure 3 As shown, the guide surface is set as an inclined surface, and is inclined from outside to inside and from high to low along the length direction of the shell 1; more specifically, a guide bar is set on the outer peripheral wall of the terminal 2, the guide bar extends along the axial direction of the terminal 2, and is set corresponding to the guide surface, and a guide hole is opened between the slot 11 and the mounting hole. The guide bar is inserted into the guide hole when in use, and can slide along the guide hole and be electrically connected to the conductive sheet 13; more specifically, the guide bar, the terminal 2 and the first clip 21 are all set to be made of conductive materials, such as copper, silver, aluminum, etc., so as to electrically connect the two terminals 2 through the conductive sheet 13.

[0039] The second clamping portion is configured to include a plurality of second clamps 23 arranged along the circumferential direction. The second clamps 23 are inserted into the terminal 2 and can slide in the radial direction to move toward the direction close to the wire under the pushing action of the guide surface. Specifically, Figure 2 As shown, the second clip 23 is tilted during installation, and a preset angle is formed between its left side and the axis of the terminal 2; more specifically, as shown Figure 3As shown, in order to facilitate the installation of the second clip 23, a plurality of mounting seats 24 are obliquely arranged on the right end surface of the terminal 2, and the plurality of mounting seats 24 are arranged along the circumferential direction. The mounting seat 24 is set as a square-shaped block structure, and the left side is fixedly connected to the right end surface of the terminal 2. The second clip 23 and the mounting seat 24 are set one by one, and are inserted into the square-shaped through hole of the corresponding mounting seat 24, and can slide along the through hole; as shown Figure 2 As shown, a plurality of spring protrusions 231 are arranged in parallel on the front and rear side surfaces of the second clip 23 and along the height direction of the second clip 23. The spring protrusions 231 can undergo elastic deformation, so that when the second clip 23 slides along the through hole on the mounting seat 24, the friction between the second clip 23 and the mounting seat 24 is increased through the deformation of the spring protrusions 231, so that the second clip 23 can better clamp the wire; more specifically, the number of guide surfaces is set to be equal to the number of second clips 23, so as to guide the movement of the corresponding second clips 23 respectively; for example, the number of second clips 23 can be set to two, and they are arranged circumferentially on the right end face of the terminal 2.

[0040] It is understandable that the plurality of second clamping pieces 23 may be arranged evenly along the circumferential direction, so as to improve the stability of the second clamping portion when clamping the wire by balancing the force on the wire when clamping the wire.

[0041] During use, if Figure 3 and Figure 5 As shown, taking the terminal 2 on the left as an example, firstly, a part of the conductive end of the wire is stripped, and then the wire is driven to pass through the terminal 2 coaxially from left to right in the horizontal direction. During the wire passing process, the conductive end firstly pushes open the multiple first clamps 21 synchronously, and is elastically clamped by the multiple first clamps 21 at the same time, so that the conductive end is electrically connected to the conductive sheet 13 through the first clamps 21, the terminal 2 and the guide strip in sequence; when the conductive end is clamped by the first clamp 21, the wire is continuously pushed to synchronously drive the terminal 2 to move horizontally from left to right. During the movement of the terminal 2, the conductive end is electrically connected to the conductive sheet 13 through the first clamps 21, the terminal 2 and the guide strip in sequence. Under the pushing action of the surface, the second clamp 23 moves toward the direction close to the wire, and then rigidly clamps the wire. During the movement of the second clamp 23, multiple elastic protrusions 231 undergo elastic deformation in turn, so that the second clamp 23 can better rigidly clamp the wire, thereby ensuring the connection stability between the wire and the terminal 2 while reducing the elastic fatigue caused by the first clamping part clamping the wire when the wire is disturbed by external force, ensuring that the wire and the terminal 2 are always in good contact, and ensuring the stability of signal transmission; the way the terminal 2 on the right clamps the wire is similar and will not be repeated.

[0042] When the first clamps 21 on the two terminals 2 clamp the conductive ends of the wires, the two wires are electrically connected through the conductive sheet 13 to perform normal signal transmission.

[0043] In other embodiments, in order to further improve the stability during signal transmission, the number of guide bars and conductive sheets 13 is equal, and multiple guide bars and conductive sheets 13 are provided in a one-to-one correspondence, thereby avoiding the situation in which the electrical connection between the two wires is unstable due to being limited to only one guide bar and one conductive sheet 13 during use; for example, the number of guide bars and conductive sheets 13 can be four, and they can be evenly arranged along the circumference.

[0044] It can be understood that the number of guide holes and mounting holes is also set to be multiple, so as to place multiple guide strips and multiple conductive sheets 13.

[0045] In other embodiments, when connecting a single multi-strand wire, the wire is prone to become loose, which in turn leads to poor contact between the wire and the connector. To solve this problem, the conductive connector of the energy device is configured to also include a rotating part, and the rotating part is configured to drive the terminal 2 to rotate so as to twist and gather the exposed part of the wire.

[0046] In this embodiment, no guide strip is provided on the outer peripheral wall of the terminal 2, and no guide hole is provided between the slot 11 and the mounting hole; the rotating portion is provided to include two spiral holes 12 and two spiral sheets 22, and the two spiral holes 12 and the two slots 11 are provided one-to-one, and are both opened on the side wall surface of the slot 11, specifically, as Figure 3 As shown, the spiral hole 12 connects the mounting hole and the slot 11, and the slot 11 is configured to be composed of a coaxially arranged truncated cone structure and a cylindrical structure, wherein the circumferential side wall surface of the truncated cone structure is configured as a guide surface; two spiral pieces 22 and two terminals 2 are arranged one by one, and are all spirally wound on the outer circumferential wall of the terminal 2. The spiral piece 22 is inserted into the spiral hole 12 when in use, and the matching direction between the spiral hole 12 is spiral matching. Specifically, the spiral piece 22 is configured to be made of a conductive material, such as copper, silver, aluminum, etc., so as to be electrically connected to the conductive piece 13.

[0047] During the movement of the terminal 2, the terminal 2 rotates around its own axis under the spiral cooperation between the spiral hole 12 and the spiral sheet 22, thereby twisting and gathering the exposed part of the wire, making the exposed part of the wire contact more closely, while maintaining the contact between the wire and the first clamping part in a rotational manner, which helps to improve the stability of the electrical connection between the wire and the first clamping part.

[0048] It can be understood that since the first clamping portion is configured to be able to elastically clamp the wire, when clamping a wire with a smaller diameter, the deflection amount of the first clamp 21 is smaller, and the deformation amount of the corresponding torsion spring is smaller, but the torsion spring can be set to have a suitable elastic modulus to ensure that the first clamp 21 can clamp and twist the wire; similarly, when clamping a wire with a larger diameter, the deflection amount of the first clamp 21 is larger, and the deformation amount of the corresponding torsion spring is larger, thereby ensuring that the first clamp 21 can clamp and twist the wire, thereby improving versatility.

[0049] In a further embodiment, the two slots 11 are symmetrically arranged, specifically, as Figure 3 As shown, the two slots 11 are arranged symmetrically about the center line of the long side of the housing 1; the spiral holes 12 in the two slots 11 have opposite rotation directions. Specifically, as Figure 3 As shown, the rotation direction of the spiral hole 12 in the left slot 11 is set to be spirally arranged from left to right and in a clockwise direction along the length direction of the shell 1, and the rotation direction of the spiral hole 12 in the right slot 11 is set to be spirally arranged from left to right and in a counterclockwise direction along the length direction of the shell 1.

[0050] During use, when the terminal 2 on the left side has a tendency to move outward under the drive of the wire, the terminal 2 on the left side has a tendency to drive the shell 1 to rotate in the counterclockwise direction, and the shell 1 simultaneously drives the terminal 2 on the right side to move inward. At this time, since the terminal 2 on the right side is at the extreme position, it cannot continue to move inward, thereby limiting the terminal 2 on the left side from escaping from the shell 1; similarly, when the terminal 2 on the right side has a tendency to move outward under the drive of the wire, the terminal 2 on the right side has a tendency to drive the shell 1 to rotate in the clockwise direction, and the shell 1 simultaneously drives the terminal 2 on the left side to move inward. At this time, since the terminal 2 on the left side is at the extreme position, it cannot continue to move inward, thereby limiting the terminal 2 on the right side from escaping from the shell 1, thereby improving the connection stability between the terminal 2 and the shell 1.

[0051] In other embodiments, a puncture portion 232 is provided on a side of the second clip 23 facing the wire, and the puncture portion 232 is configured to partially penetrate or pierce the insulation of the wire.

[0052] In this embodiment, the puncture portion 232 is configured as a cone-shaped structure, specifically, as shown in FIG. Figure 4 As shown, the puncture portion 232 can be set as a pyramidal structure, and then during the movement of the terminal 2, the second clamp 23 moves toward the direction close to the wire under the pushing action of the guide surface until the puncture portion 232 partially penetrates or pierces the insulation of the wire, thereby better rigidly clamping the wire.

[0053] It is understandable that the depth of the puncture portion 232 piercing the wire can be changed by changing the length of the busbar of the truncated cone structure in the slot 11 and changing the pushing distance of the guide surface to the second clamp 23 .

[0054] It can be understood that when the puncture portion 232 is configured to pierce the insulation of the wire, it can drive the wire to continue to move inward, and then the insulation can be elastically deformed under the blocking effect of the puncture portion 232, so that the insulation exerts a pre-tightening force on the terminal 2, further improving the connection stability between the terminal 2 and the connector.

[0055] It is understandable that the puncture portion 232 may also be configured as a conical structure.

[0056] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
