Description

Technical Field

[0001] The present invention relates to the field of electrical connectors, and in particular to an electrical connector that is easy to operate. Background Art

[0002] An electrical connector (or terminal block) is a device frequently used in the field of electric power. An existing electrical connector comprises a first insulating shell and a second insulating shell that are assembled together, wherein the first insulating shell is provided with a wiring hole for inserting a conductive wire, and the second insulating shell is provided with a conductor. A clamping spring is also provided in the space formed after the first insulating shell and the second insulating shell are assembled, and one end of the clamping spring is fixed on the conductor. When wiring is required, an external tool is used to apply downward pressure to the clamping spring directly or indirectly, so that the clamping spring undergoes elastic deformation and moves downward after being subjected to force, and then the conductive wire is passed through the wiring hole and the space formed by the downward movement of the clamping spring. After the downward pressure on the clamping spring is released, the clamping spring moves upward under the elastic restoring force to clamp the conductive wire, thereby achieving an electrical connection between the connected conductive wire and the conductor.

[0003] Chinese invention patent CN101562282B discloses an electrical connector, comprising at least two insulating bases, a welding piece, a spring and a button spliced ​​together, the base being provided with a wiring hole for inserting a conductive wire, the welding piece being fixedly arranged in the base, the spring being connected to the welding piece, the spring comprising a free end and a fixed end, the free end having a tendency to always abut against the welding piece, the fixed end being fixedly connected to the welding piece; the button being connected to the upper part of the base, the bottom end of the button abutting against the free end of the spring, and the welding piece further comprising a current-carrying main board, the lower part of the current-carrying main board protruding with a support sheet that can abut against the bottom of the fixed end, the upper edge of the current-carrying main board being folded outward to form a rib that can abut against the top of the free end, the current-carrying main board, the support sheet and the rib of the welding piece forming a C-shaped cross section, and the bottom of the welding piece also being integrally formed with two welding feet respectively located on both sides of the support sheet and staggered front and back. Compared with the prior art, the soldering piece of the present invention has a larger current-carrying area, which improves the conductive performance of the soldering piece; the soldering feet are staggered front and back, which increases the creepage distance, thereby increasing the voltage resistance value of the electrical connector and further improving the electrical strength of the product.

[0004] However, during actual use of the electrical connector in the above-mentioned invention patent CN101562282B, when the spring is deformed by the movement of the button and is in the open state, even if the spring has formed a sufficient insertion gap for the connected conductive wire, the spring cannot remain in the position corresponding to the current open state. That is, the spring cannot stop in the open position, and the user must continue to apply force to the spring through the button, which is inconvenient for wiring the conductive wire.

[0005] Chinese invention patent CN107078414B discloses a terminal having the following features: a) at least one insulating material housing, b) at least one contact plug at least partially arranged in the insulating material housing, the contact plug having at least one contact piece and at least one clamping spring, c) wherein the contact piece and the clamping spring form at least one conductive wire clamping location for an electrically conductive wire to be contacted by means of the terminal, the electrically conductive wire being capable of being loaded with the spring force of the clamping spring at the conductive wire clamping location, d) at least one operating lever pivotably supported in the insulating material housing, the operating lever being used to operate the clamping spring, the operating lever being capable of pivoting relative to the insulating material housing and / or the contact piece from a closed position to an open position and vice versa, and at least in the open position, the electrically conductive wire introduced into the terminal is not loaded with the spring force of the clamping spring at the conductive wire clamping location, e) wherein the operating lever is floatingly supported and at least partially supported on the contact piece at least in the open position.

[0006] However, in the wiring terminal of the above-mentioned invention patent CN107078414B, if the user manually operates the joystick, the joystick will generate a large impact force when resetting, which is very easy to injure the user's hand and is inconvenient for wiring operations. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide an easy-to-operate electrical connector for the above-mentioned prior art.

[0008] The technical solution adopted by the present invention to solve the above technical problems is: an easy-to-operate electrical connector, comprising:

[0009] The first insulating housing has a wiring hole for inserting the conductive wire;

[0010] a second insulating shell, assembled with the first insulating shell;

[0011] At least one operating member is provided on the first insulating housing;

[0012] At least one electrical conductor is located in a space formed by assembling the first insulating housing and the second insulating housing and corresponds to the wiring hole;

[0013] and at least one elastic clamping member located in a space formed by assembling the first insulating housing and the second insulating housing; wherein the elastic clamping member comprises a fixed portion and an elastic free portion connected together, the fixed portion being fixed on the electrical conductor;

[0014] It is characterized in that the operating member is movably arranged on the first insulating shell, and when the operating member moves under force, the operating member presses the elastic free portion of the elastic clamping member, so that a gap is formed between the elastic free portion and the electrical conductor for the conductive wire passing through the wiring hole to pass through; wherein, the electrical connector has a limiting structure for limiting the maximum moving stroke of the operating member; when the operating member moves to the maximum moving stroke, the operating member maintains an open state under the action of the first insulating shell, the second insulating shell and the elastic clamping member.

[0015] When the electrical connector of the invention needs to be wired, the user applies force to the operating member to move the operating member relative to the first insulating shell. The moving operating member applies a top pressure to the elastic free portion of the elastic clamping member, causing the elastic free portion of the elastic clamping member to be forced to move downward, and as the operating member moves to its maximum movement stroke, the gap formed between the elastic free portion of the elastic clamping member and the electrical conductor also changes to the maximum. At this time, the electrical connector is in an open state, and the operating member is limited to the current maximum movement stroke state by the limiting structure of the electrical connector. At this time, the operating member maintains an open state under the action of the first insulating shell, the second insulating shell and the elastic clamping member. The user does not need to apply force to the operating member to keep the electrical connector in an open state, thereby making it convenient for the user to connect the external conductive wire to the interior of the electrical connector or to remove the conductive wire that has been connected to the interior of the electrical connector.

[0016] Specifically, in the electrical connector of the present invention, the operating member includes:

[0017] A force-bearing portion located outside the first insulating shell;

[0018] a rotating portion rotatably disposed on the first insulating housing;

[0019] The pressing portion is located on the inner side of the first insulating shell and contacts the elastic free portion of the elastic clamping member when the operating member is not subjected to an operating force.

[0020] In addition, as a way to realize the rotation setting of the rotating part on the first insulating shell, in the electrical connector of this invention, one end of the force-bearing part is extended to form at least one force-applying arm, the end of the force-applying arm has the pressing part, and the force-applying arm has a moving axis, and the first insulating shell is formed with a track groove for placing the moving axis for movement and rotation; wherein, the moving axis is the rotating part.

[0021] In order to facilitate the user to manually operate the operating member, in the electrical connector of the invention, the track groove is formed on the top of the first insulating shell.

[0022] Furthermore, in the electrical connector of this invention, the second insulating housing cooperates with the track groove on the first insulating housing to form a limiting structure that limits the maximum travel of the operating member. Thus, when the operating member moves due to a force, the motion axis moves along the track groove, and after being limited by the limiting structure, the operating member is now moved to its maximum travel under the action of the pulling force, and the elastic free portion of the elastic clamping member is also pressed to its maximum downward position by the force applied by the operating member. At this point, the electrical connector is in an open state, and the user can connect an external conductive wire to the interior of the electrical connector or remove a conductive wire that has already been connected to the electrical connector without the need for operating tools.

[0023] In addition, in the electrical connector of the present invention, the electrical conductor includes:

[0024] The electric conductor body is vertically arranged in a space formed by assembling the first insulating shell and the second insulating shell;

[0025] An electrical contact portion is formed at the upper end of the electrical conductor body, and the electrical contact portion is located at the upper end of the elastic free portion of the elastic clamping member;

[0026] The pair of plug-in assembling parts are formed on the electrical conductor body and located below the electrical contact part. The pair of plug-in assembling parts are arranged in the second insulating shell; wherein the fixing part of the elastic clamping member is fixed on the pair of plug-in assembling parts.

[0027] To facilitate assembly of the two insulating housings and ensure a secure fit after assembly, in this invention, the first and second insulating housings are assembled together using a cooperating snap-fit ​​structure. For example, the first insulating housing may have a first locking member, and the second insulating housing may have a first slot formed therein that locks with the locking member; or / and the first insulating housing may have a second slot formed therein, and the second insulating housing may have a second locking member that locks with the slot. Of course, the first and second locking members may have the same structural form, and accordingly, the first and second slots may also have the same structural form.

[0028] Compared with the prior art, the advantages of the present invention are:

[0029] First, when the user needs to connect or remove wires, the user applies force to the operating part of the electrical connector to move the operating part. The moving operating part applies a top pressure to the elastic free part of the elastic clamping part, so that the elastic free part of the elastic clamping part is forced to move downward, and as the operating part moves to its maximum movement stroke, the gap formed between the elastic free part of the elastic clamping part and the electrical conductor also changes to the maximum. At this time, the electrical connector is in an open state for the conductive wire to be connected or removed, and after the operating part is limited by the limiting structure, the operating part maintains the open state under the action of the first insulating shell, the second insulating shell and the elastic clamping part. The user does not need to apply force to the operating part to put the electrical connector in an open state, and does not need to use any operating tools, thereby facilitating the user to connect or remove the conductive wire.

[0030] Secondly, during the wiring operation of the electrical connector, the operating member will not generate impact force when resetting, and thus the user's hand will not be injured by the impact force of the operating member. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0044] like Figures 1 to 10 As shown, this embodiment provides an electrical connector that is easy to operate, including:

[0045] The first insulating housing 1 has a wiring hole 10 for inserting a conductive wire;

[0046] The second insulating housing 2 is assembled with the first insulating housing 1 through a mutually cooperating snap-fit ​​structure;

[0047] An operating member 3 is provided on the first insulating housing 1;

[0048] The electrical conductor 4 is located in the space formed by assembling the first insulating housing 1 and the second insulating housing 2 and corresponds to the wiring hole 10. The electrical conductor 4 includes an electrical conductor body 40, an electrical contact portion 41, and a plug-in assembly portion 42. The electrical conductor body 40 is vertically arranged in the space formed by assembling the first insulating housing 1 and the second insulating housing 2. The electrical contact portion 41 is formed at the upper end of the electrical conductor body 40. The plug-in assembly portion 42 is formed on the electrical conductor body 40 and is located below the electrical contact portion 41. The plug-in assembly portion 42 is arranged in the second insulating housing 2.

[0049] The elastic clamping member 5 is located in the space formed after the first insulating shell 1 and the second insulating shell 2 are assembled; wherein, the elastic clamping member 5 has a fixed portion 51 and an elastic free portion 52 connected together, and the fixed portion 51 is fixed on the electrical conductor 4; wherein, the fixed portion 51 of the elastic clamping member 5 is fixed on the plug-in assembly portion 42 of the electrical conductor 4, and the electrical contact portion 41 of the electrical conductor 4 is located at the upper end of the elastic free portion 52 of the elastic clamping member 5.

[0050] In this embodiment, the operating member 3 is movably disposed on the first insulating housing 1. When the operating member 3 is moved by a pulling force, the operating member 3 applies force to the elastic free portion 52 of the elastic clamping member 5, thereby forming a gap between the elastic free portion 52 and the electrical contact portion 41 of the electrical conductor 4 for the conductive wire to pass through. The second insulating housing 2 cooperates with the first insulating housing 2 to form a limit structure that limits the maximum travel of the operating member 3. When the operating member 3 moves to its maximum travel, it remains in an open state under the action of the first insulating housing 1, the second insulating housing 2, and the elastic clamping member 5.

[0051] See also Figures 3-5 As shown, specifically, the first insulating shell 1 of this embodiment has a first locking member 6, and the second insulating shell 2 is formed with a first card slot 7 that is locked with the first locking member 6. The first insulating shell 1 and the second insulating shell 2 are assembled together through the lock fit between the first locking member 6 and the first card slot 7. Of course, according to actual design requirements, the first insulating shell 1 can also have a second card slot 7', and the second insulating shell 2 can be formed with a second locking member 6' that is locked with the second card slot 7'. The first locking member 6 and the second locking member 6' are preferably set to the same structural form, and correspondingly, the first card slot 7 and the second card slot 7' are also set to the same structural form. In this way, through the cooperation of the two sets of locking structures, the first insulating shell 1 and the second insulating shell 2 can be firmly assembled together.

[0052] See also Figures 6-11 As shown, the operating member 3 of this embodiment includes a force-bearing portion 31 and a pressing portion 32. The force-bearing portion 31 is located on the outside of the first insulating shell 1, and two symmetrical force-applying arms 33 are formed at one end of the force-bearing portion 31. The force-applying arms 33 are movably arranged on the first insulating shell 1. The end of each force-applying arm 33 has the above-mentioned pressing portion 32. The pressing portion 32 is located on the inner side of the first insulating shell 1, and when the operating member 3 is not subjected to a pulling force, it contacts the elastic free portion 52 of the elastic clamping member 5. Among them, the force-bearing portion 31 in this embodiment is configured as a pulling member structure for the user to apply a pulling force. The force-applying arm 33 here has a moving shaft 331, and a track groove 11 for placing the moving shaft 331 is formed on the top of the first insulating shell 1. The moving shaft 331 can move along the formation direction of the track groove 11 and rotate in the track groove 11. In this way, the operating member 3 can be movably arranged on the first insulating housing 1 through the cooperation between the moving shaft 331 and the track groove 11, so that the force-bearing portion 31 moves toward the second insulating housing 2 through the movement and rotation of the moving shaft 331 in the track groove 11, thereby causing the pressing portion 32 to gradually apply a pressing force to the elastic free portion 52 of the elastic clamping member 5. Figure 11 and Figure 12 As shown, in this embodiment, the cross section of the movement shaft 331 has an edge line forming an angular edge and an arc edge connected to the edge line.

[0053] In addition, in this embodiment, as one implementation of the aforementioned position-limiting structure, a stop portion can be formed on the second insulating housing 2 to limit the travel of the force-applying arm 33 of the operating member 3. That is, when the operating member 3 moves toward the second insulating housing 2 along with the movement of the motion shaft 331, once the force-applying arm 33 contacts the stop portion of the second insulating housing 2, the operating member 3 cannot continue to move toward the second insulating housing 2. The operating member 3 is now blocked by the stop portion of the second insulating housing 2, and the operating member 3 is limited to the current open state. The stop portion is positioned at the position corresponding to the maximum travel of the operating member 3.

[0054] It should be noted that the operating member 3 in this embodiment has two symmetrical pressing portions 32. By pressing the elastic free portion 52 of the elastic clamping member 5 through these two pressing portions 32, it can be ensured that the operating member 3 can more stably open the gap between the elastic free portion 52 and the electrical contact portion 41 of the electrical conductor 4. Unlike traditional electrical connectors, there is no need to use tools to press the operating member on the operating portion to open the gap between the elastic free portion and the electrical conductor. This ensures that the electrical connector in this embodiment is more convenient to operate.

[0055] That is to say, when the operating member 3 is pulled, the moving shaft 331 can move and rotate along the track groove 11, and after the operating member 3 contacts the second insulating shell 2 due to the movement of the moving shaft 331 (the movement here includes both movement and rotation), the second insulating shell 2 and the first insulating shell 1 at this time jointly form a limiting structure to limit the moving shaft 331 so that it cannot continue to move. At this time, the operating member 3 is just moved to its maximum moving stroke under the action of the pulling force, and the elastic free portion 52 of the elastic clamping member 5 is also just pressed to the maximum downward position by the force of the operating member. At this time, the electrical connector is in an open state, so that the external conductive wire can be connected to the interior of the electrical connector or the conductive wire that has been connected to the interior of the electrical connector can be removed without the help of an operating tool.

[0056] In addition, in traditional electrical connectors, some traditional electrical connectors must form a wall opening for the extension of the elastic free portion of the elastic clamping member to pass through and a partition on the electrical conductor body, so that when opening the above-mentioned gap, the operating member needs to press the elastic free portion. The elastic free portion can easily collide with the wall opening of the electrical conductor body during the downward pressing process, affecting the opening effect of the above-mentioned gap and the user's experience. Moreover, the setting of the partition will also increase the structural complexity of the electrical conductor body and increase the production complexity of the electrical conductor body. In order to avoid the above-mentioned situation of traditional electrical connectors, the electrical connector of this embodiment does not need to specially form the above-mentioned wall opening on the electrical conductor body, nor does it need to form the above-mentioned partition on the electrical conductor body. The electrical conductor body is directly formed by the electrical conductor body 40, the electrical contact part 41 and the plug-in assembly part 42. In this way, the elastic free part of the elastic clamping part can be pressed under the action of the top pressure applied by the operating part. The implementation structure and assembly operation of the electrical conductor body are simpler, and the above-mentioned collision situation does not occur, which improves the opening effect of the above-mentioned gap and the user's experience. Moreover, because there is no partition, the structure of the electrical conductor body can be simplified, and the production efficiency of the electrical conductor body and the assembly efficiency of the entire electrical connector can be improved.

[0057] The following describes the wiring operation of the electrical connector in this embodiment:

[0058] When the electrical connector of this embodiment needs to be wired, when the user manually applies a pulling force to the force-bearing portion 31, the operating member 3 gradually moves relative to the first insulating housing 1, and the force-bearing portion 31 is gradually pulled up. The moving shaft 331 of the operating member 3 moves and rotates in the track groove 11 of the first insulating housing 1 along the direction formed by the track groove 11. The pressing portion 32 of the operating member 3 continuously applies a pressing force to the elastic free portion 52 of the elastic clamping member 5, causing the elastic free portion 52 to deform and move downward. As the pulling force is continuously applied to the force-bearing portion 31, the moving shaft 331 continues to move along the track groove 11, and the elastic free portion 52 also continues to move downward under the action of the pressing force of the pressing portion 32.

[0059] When the moving shaft 331 moves in the track groove 11 to be limited by the above-mentioned limiting structure, the operating member 3 is moved to its maximum moving stroke under the action of the pulling force and is roughly in a vertical state, and the elastic free portion 52 of the elastic clamping member 5 is also pressed to the maximum downward position by the force applied by the operating member. At this time, the electrical connector is in an open state, and a gap for the conductive wire to pass through is formed between the elastic free portion 52 and the electrical contact portion 41 of the electrical conductor 4. The external conductive wire can be connected to the interior of the electrical connector to make the conductive wire electrically contact with the electrical contact portion 41 of the electrical conductor 4.

[0060] Then, the user manually applies a reverse pulling force to the force-bearing part 31, so that the moving shaft 331 is no longer limited by the above-mentioned limiting structure. At this time, the pressing part 32 of the operating part 3 will not continue to apply downward pressing pressure to the elastic free part 52 of the elastic clamping part 5. The elastic free part 52 deforms again under the action of the elastic restoring force and squeezes the conductive wire, thereby ensuring that the connected conductive wire maintains good electrical contact with the electrical conductor.

[0061] Of course, if it is necessary to remove the conductive wire that has been connected to the inside of the electrical connector, it is necessary to apply a pulling force to the force-bearing part 31 again to move the operating part 3 to its maximum moving stroke, and the electrical connector is in an open state, so that the connected conductive wire can be removed from the inside of the electrical connector without the need for operating tools.

[0062] It can be seen that when performing wiring operations on the electrical connector of this embodiment, the user does not need to use operating tools to put the electrical connector into an open state, and at this time the user does not need to continue to apply pulling force. The elastic clamping member of the electrical connector can pause at the position corresponding to the current open state to maintain the open state of the electrical connector, which facilitates the user's operation.

[0063] Furthermore, during the wiring operation of the electrical connector, the operating member will not generate any impact force when resetting, and thus the user's hand will not be injured by the impact force of the operating member.
