Compared with the prior art, the electrical connection device provided by the embodiment of the utility model has the advantages that the second conductive component 22 is arranged on the insulating support 21, so that the second conductive component 22 and the insulating support 21 jointly enclose to form the rotating part 23, then the rotating part 23 is arranged in the rotating cavity 111, and a certain friction force is formed between the rotating part 23 and the cavity wall of the rotating cavity 111, and the friction force can form a static friction balance state between the rotating part 23 and the cavity wall of the rotating cavity 111, so that the first connection mechanism 10 and the second connection mechanism 20 cannot easily rotate without artificial external force active intervention; when the user needs to adjust the relative angle between the first connecting mechanism 10 and the second connecting mechanism 20, the user rotates the first connecting mechanism 10 or the second connecting mechanism 20 manually to break the balance state, so that the first connecting mechanism 10 or the second connecting mechanism 20 can rotate freely in a large-angle conical three-dimensional space, the rotatable range is extremely wide, the rotation is not limited to 360 degrees in a certain direction, and the use direction of the executing component can be adjusted at any time and in a large range according to the requirement when the user uses the electric product, thereby bringing great convenience to the user and achieving good use experience of the user.

And, by providing the first conductive member 12 on the first connecting mechanism 10, and the second conductive member 22 on the second connecting mechanism 20, so that when the electric product is electrified, the first connecting mechanism 10 and the second connecting mechanism 20 can be electrically connected with each other no matter in relative rest or relative rotation, therefore, invisible electric connection is realized in the rotating cavity 111, the use is convenient and attractive, extra wires do not need to be additionally arranged on an executing part of an electric product to be connected with a power supply, and the extra wires do not need to be additionally arranged between the first connecting mechanism 10 and the second connecting mechanism 20 to be electrically connected, so that the limitation of the exposed wires to the relative rotation between the first connecting mechanism 10 and the second connecting mechanism 20 is avoided, the rotation adjustment between the first connecting mechanism 10 and the second connecting mechanism 20 is facilitated, and the use effect is good.

In one embodiment, as shown in fig. 2 and 3, the first conductive member 12 includes two spaced apart contact conductive members 121, the contact conductive members 121 are mounted on the wall of the rotating chamber 111, and the contact conductive members 121 are configured to abut and make electrical contact with the second conductive member 22. Specifically, two contact conductive members 121 are spaced apart on the insulating base 11 to avoid short circuit due to electrical contact between the two contact conductive members 121. When the contact conductive assembly 121 is installed, an installation cavity can be arranged on the cavity wall of the rotation cavity 111, one end of the contact conductive assembly 121 is installed in the installation cavity and is electrically connected with an electric wire preset on the insulating base 11, and the other end of the contact conductive assembly 121 extends into the rotation cavity 111 to abut against the second conductive assembly 22 and form an electrical contact, so that the second conductive assembly 22 is electrically connected with the first conductive assembly 12 inside the rotation cavity 111. The contact conductive assembly 121 may be a spring thimble commonly used in an electronic test, or an elastic conductive sheet (such as a copper sheet, an iron sheet, etc.) or a conductive ball (such as a copper ball, an iron ball, etc.); when the contact conductive element 121 is a pogo pin commonly used in electronic testing, the pogo pin is elastically abutted against the second conductive element 22 under the action of an inner spring of the pogo pin to form an electrical contact. The electric wire preset on the insulating base 11 is connected to a power supply direction (the power supply direction may be a power supply on a socket, a rechargeable power supply on a portable electric product, or other electric devices), or is connected to an execution component of the electric product, and is set as required. The insulating base 11 is a supporting base made of an insulating material with a certain structural strength, such as hard plastic or other insulating metals.

In one embodiment, as shown in fig. 2, 4 and 7, the second conductive component 22 includes two arc-shaped conductive members 221, the two arc-shaped conductive members 221 are oppositely mounted on the insulating support 21, and the two arc-shaped conductive members 221 are respectively used for abutting and making electrical contact with the two contact conductive components 121. Specifically, the two arc-shaped conductive members 221 may be fixedly mounted on the insulating support 21 by a fastener or other conventional fixing means, and the insulating support 21 not only supports and fixes the two arc-shaped conductive members 221, but also insulates the two arc-shaped conductive members 221 to prevent short circuit between the two arc-shaped conductive members 221 due to electrical contact. Moreover, the two arc-shaped conductive pieces 221 are relatively and fixedly mounted on the insulating support 21, and the rotating piece 23 matched with the rotating cavity 111 is formed between the two arc-shaped conductive pieces 221 and the insulating support 21, so that the two contact conductive components 121 can be electrically contacted with the two arc-shaped conductive pieces 221 in the rotating cavity 111 well, that is, the two contact conductive components 121 and the arc-shaped conductive pieces 221 can be electrically contacted in the rotating cavity 111 well in a relatively rotating state or a relatively static state, so that when a user uses the electric appliance, the user can drive the two arc-shaped conductive pieces 221 to rotate in the rotating cavity 111 by rotating the insulating support 21, and the user can adjust the use direction of the executing component of the electric appliance in a large range according to the needs. The two arc-shaped conductive pieces 221 are respectively connected with an electric wire reserved on the insulating support 21, and the electric wire is connected with a power supply direction (the power supply direction can be a power supply on a socket, and can also be a rechargeable power supply on a portable electric product, or other electric devices); or is connected with an actuating component of the electric product and is arranged as required. Further, the electric wire connected to the arc-shaped conductive member 221 may be disposed inside the insulating support 21 to make the appearance beautiful. And, can connect the extension piece 213 that extends out the opening that rotates the chamber 111 on the insulating support 21, the user can rotate insulating support 21 through rotating extension piece 213 like this, convenient to use, wherein the hookup location between extension piece 213 and the insulating support 21 is under the prerequisite of guaranteeing certain joint strength, and is as little as possible to reduce the influence of extension piece 213 to rotating the angle of rotation 23. The arc-shaped conductive member 221 may be made of a common conductive metal material such as copper or aluminum; the insulating support 21 may be made of a material having a certain structural strength, such as hard plastic or a non-conductive metal.

In one embodiment, as shown in fig. 4, 5 and 7, the insulating support 21 has an insulating surface 211 between two arc-shaped conductive members 221, and the width of the insulating surface 211 is greater than the contact area between the contact conductive member 121 and the insulating surface 211. Specifically, by making the width of the insulating surface 211 larger than the contact area between the contact conductive member 121 and the insulating surface 211, when the contact conductive member 121 is located between two arc-shaped conductive members 221, the two arc-shaped conductive members 221 are not short-circuited, and the electric product is not burned out due to short-circuiting. The insulating surface 211 may be flush with the outer surface between the two arc-shaped conductive members 221, so that the outer surface of the rotating member 23 is smooth, which facilitates the rotating member 23 to rotate smoothly in the rotating cavity 111. Of course, the insulating surface 211 may be disposed not flush with the outer surface between the two arc-shaped conductive members 221, as required.

In one embodiment, as shown in fig. 4, 5 and 6, two separate arcuate slots 212 are provided along the arcuate length of the insulating surface 211, and the contact conducting members 121 can slide into and out of the arcuate slots 212. Specifically, by arranging two independent arc-shaped grooves 212 in the arc-shaped length direction of the insulating surface 211, when the contact conductive assembly 121 slides into the arc-shaped grooves 212, a significant pause can be generated, so that a user knows that the rotating member 23 rotates to a specific position in the rotating cavity 111, and can effectively play a role in positioning, and the contact conductive assembly 121 can also rotate in the arc-shaped grooves 212 in the length direction of the arc-shaped grooves 212, so that a specific required rotating direction can be realized; for example, for safety, the contact conducting member 121 may be slid into the arc-shaped groove 212, so that the contact conducting member 121 cannot electrically contact with the arc-shaped conducting member 221, and therefore the first conducting member 12 and the second conducting member 22 cannot be electrically connected regardless of the rotation of the contact conducting member 121 in the arc-shaped groove 212; when the first conductive assembly 12 and the second conductive assembly 22 are electrically connected, the user slides the contact conductive assembly 121 out of the arc-shaped groove 212 to abut against the arc-shaped conductive member 221, which is convenient and reliable to use. In addition, the contact conductive assembly 121 slides into the arc-shaped groove 212, so that the insulation effect can be better achieved, the short circuit between the two arc-shaped guide pieces at the position of the contact conductive assembly 121 is avoided, and the use is safe.

The arc length direction is the length direction of the elongated arc-shaped insulating surface 211 sandwiched between the two arc-shaped conductive members 221, and the two arc-shaped grooves 212 are arranged on the insulating surface 211 and extend in the same direction as the insulating surface 211. Further, two arc-shaped slots 212 may be symmetrically disposed on the insulating surface 211.

In one embodiment, as shown in fig. 4, 5 and 6, second conductive element 22 further includes two conductive strips 222, wherein conductive strips 222 are disposed at the bottom of arc-shaped slot 212 and extend in the same direction as arc-shaped slot 212, and conductive strips 222 are used for electrically contacting contact conductive element 121. Specifically, the conductive strips 222 are respectively arranged at the bottoms of the two independent arc-shaped grooves 212 to insulate the two conductive strips 222, so that when the two contact conductive assemblies 121 respectively slide into the two arc-shaped grooves 212, the two contact conductive assemblies 121 can be respectively electrically connected with the two conductive strips 222, and thus after the two contact conductive assemblies 121 slide into the arc-shaped grooves 212 with specific positions, the first conductive assembly 12 and the second conductive assembly 22 can be electrically connected to meet specific requirements; also, by having conductive strip 222 extend in the same direction as arcuate slot 212, electrical connection between first conductive member 12 and second conductive member 22 is maintained as contact conductive member 121 rotates within arcuate slot 212 along the length of arcuate slot 212. The conductive strip 222 may be mounted in the arc-shaped slot 212 by conventional fixing means such as fasteners or adhesive bonding, which ensures that the conductive strip 222 can rotate with the rotation of the insulating support 21. The conductive strip 222 may be made of a common conductive metal material such as copper or aluminum.

In one embodiment, as shown in fig. 4, 5 and 7, the walls of the arc-shaped slot 212 are tangent to the outer surface of the conductive strip 222, and the height of the two sides of the conductive strip 222 facing the opening of the arc-shaped slot 212 is lower than the opening of the arc-shaped slot 212. Specifically, the groove wall of arc-shaped groove 212 and the outer surface of conductive strip 222 are both arc-shaped, and by making the groove wall of arc-shaped groove 212 tangent to the outer surface of conductive strip 222, a smooth "U" -shaped groove is formed between the groove wall of arc-shaped groove 212 and conductive strip 222 in the opening direction of arc-shaped groove 212, which is beneficial to sliding contact conductive member 121 into or out of arc-shaped groove 212. Through making the outer surface of conducting strip 222 be the arc form, like this when contact conducting assembly 121 slides in arc groove 212, can increase the electric contact area between contact conducting assembly 121 and the conducting strip 222 effectively to increase the stability of electric contact between contact conducting assembly 121 and the conducting strip 222, excellent in use effect. Through making the both sides of conducting strip 222 be less than the opening of arc wall 212 towards the height of the opening direction of arc wall 212, like this when contact conducting assembly 121 roll-off arc wall 212, alright realize breaking away from the electric contact with conducting strip 222, avoid appearing the short circuit, increase the security of using. The width between the openings of the arc-shaped groove 212 may be set to be equal to, slightly larger than, or slightly smaller than the size of the abutting conductive piece 1212, so as to facilitate the abutting conductive piece 1212 to slide into or out of the arc-shaped groove 212.

In one embodiment, as shown in fig. 2 and 3, contact conducting assembly 121 includes a resilient conducting member 1211 mounted on the wall of rotation chamber 111 at one end of resilient conducting member 1211 and an abutting conducting member 1212 mounted at the other end of resilient conducting member 1211, abutting conducting member 1212 may be resiliently abutted against and brought into electrical contact with arcuate conducting member 221 by resilient conducting member 1211, and abutting conducting member 1212 may be slid into or out of arcuate slot 212 by resilient conducting member 1211. Specifically, the wall of the rotation cavity 111 has a mounting cavity, one end of the elastic conductive element 1211 is mounted in the mounting cavity and electrically connected to the electric wire preset in the insulating base 11, the other end of the elastic conductive element 1211 extends toward the arc-shaped conductive element 221, so that the abutting conductive element 1212 is kept abutting against the arc-shaped conductive element 221 under the elastic force of the elastic conductive element 1211, and the elastic conductive element 1211 itself has a conductive function, so that the abutting conductive element 1212 can always abut against the arc-shaped conductive element 221 and maintain a good electrical contact under the action of the elastic conductive element 1211, thereby ensuring the stability of the electrical contact between the first conductive component 12 and the second conductive component 22, and achieving a good use effect. And by providing resilient conductive member 1211 to facilitate sliding abutting conductive member 1212 into or out of arcuate slot 212, resilient conductive member 1211 springs abutting conductive member 1212 into arcuate slot 212 with its own resilience when abutting conductive member 1212 is slid to the position of arcuate slot 212 and maintains a resilience such that abutting conductive member 1212 makes electrical contact with conductive strip 222; when it is necessary to slide abutting conductor 1212 out of arc-shaped slot 212, the user rotates insulating holder 21, so that abutting conductor 1212 is driven by external force to overcome the elastic force of elastic conductor 1211 and slide out of arc-shaped slot 212, which is convenient and reliable. The elastic conductive element 1211 may be made of a copper or iron elastic element, or a common elastic element plated with a conductive material with good conductivity (such as silver or copper); the abutting conductive element 1212 may be made of a common conductive metal material such as copper or aluminum.

In one embodiment, as shown in fig. 3, resilient conductive element 1211 includes a mounting tube 12111 having one end of mounting tube 12111 mounted to the wall of rotation chamber 111 and the other end of mounting tube 12111 extending toward second conductive component 22, an abutting conductive element 1212 movably mounted to mounting tube 12111 at an end adjacent to second conductive component 22, and a strip spring 12112 disposed within mounting tube 12111 and abutting between mounting tube 12111 and abutting conductive element 1212 to resiliently abut and electrically contact abutting conductive element 1212 to second conductive component 22. Specifically, mounting tube 12111 and/or strip spring 12112 are made of a common conductive material, and mounting tube 12111 and/or strip spring 12112 are electrically connected to a wire preset on insulating base 11, so that good electrical conduction is achieved between the wire on insulating base 11 and abutting conductive element 1212, and electrical contact is achieved while abutting conductive element 1212 against second conductive assembly 22. By movably mounting abutting conductor 1212 on mounting tube 12111 such that abutting conductor 1212 contacts rotor 23, abutting conductor 1212 may move back and forth within mounting tube 12111 along the length of mounting tube 12111 under the combined action of bar spring 12112 and rotor 23 such that the resilient abutment between abutting conductor 1212 and rotor 23 may be maintained. Further, abutting conductive element 1212 may be set to be spherical, so that when rotating element 23 rotates, abutting conductive element 1212 may rotate along with rotating element 23 on mounting tube 12111, so as to reduce the friction force generated when abutting conductive element 1212 and rotating element 23 roll relatively, so that rotating element 23 rotates more smoothly, and the surface scratches of abutting conductive element 1212 and second conductive component 22 may also be better prevented, which effectively prolongs the service life.

In one embodiment, as shown in fig. 3, the contact surface abutting conductor 1212 for contact with rotor 23 is an arcuate surface.
