Description

Technical Field

[0001] The invention belongs to the technical field of connection terminals, and in particular relates to a quick connection terminal. Background Art

[0002] Quick-connect terminals are a type of connector device used to quickly connect wires. They are usually used in situations where wires need to be frequently removed and reconnected. Their advantage is that they can significantly improve the efficiency of installation and maintenance while ensuring the reliability of the connection. They are currently widely used in industrial automation, electronic equipment, lighting systems, household appliances and other fields.

[0003] Traditional quick-connect terminals only rely on plug plates and slots to be connected to each other. When subjected to external force impact, they are easily separated from each other and have poor stability. To solve this problem, a patent document with announcement number CN118380798A discloses a quick-connect terminal that is easy to use in combination. Vertical slots and vertical plug plates are respectively provided on both sides of the terminal body. A mounting groove and a horizontal slot are provided at the bottom of the terminal body. A horizontal plug plate is movably connected in the mounting groove. When multiple terminal bodies are used in combination, the vertical plug plates are inserted into the vertical slots, and the horizontal plug plates are inserted into the horizontal slots to fix the terminal bodies in both horizontal and vertical directions.

[0004] However, the orientation of the wiring holes of the combined terminal bodies is consistent, that is, the orientation of the wires they can connect is also consistent. In actual use, since the terminal bodies that are combined with each other are independent of each other, the wires they connect are naturally independent of each other. When the orientations of the wires to be connected to different terminal bodies are inconsistent, some of the wires may need to be significantly bent, which will affect the stability and reliability of the connection of these wires when used for a long time. Summary of the invention

[0005] The existing quick-connect terminals can only be connected in the same direction when used in combination, which may require some wires to be bent significantly, affecting the stability of the wire connection during long-term use. To solve this problem, the following invention is proposed:

[0006] A quick-connect terminal comprises a terminal body, wiring holes are provided at both ends of the terminal body, connecting grooves and connecting sleeves are respectively provided on both sides of the terminal body, connecting grooves are provided with connecting columns and a first snap-fitting opening, and the connecting sleeve is provided with a first snap-fitting plate. After the first snap-fitting plate is inserted into the connecting groove, the connecting sleeve is movably connected to the connecting column to combine different terminal bodies. After the terminal body rotates around the connecting column, the first snap-fitting plate rotates in the connecting groove and is blocked by the first snap-fitting opening to prevent horizontal movement between the terminal bodies. A plurality of arc-shaped positioning sockets are provided at the bottom of the terminal body, and a horizontally movable positioning column is provided in one of the positioning holes. After the positioning column is inserted into any one of the positioning holes on the other terminal bodies, relative rotation between the terminal bodies is prevented.

[0007] Furthermore, a plurality of positioning arms arranged in an arc are provided at the bottom of the terminal body, and positioning holes are provided on the positioning arms, wherein a column hole is provided on the inner side of one of the positioning holes, and a positioning column that can be moved horizontally is movably provided in the column hole. The positioning column is inserted into different positioning holes to combine and fix the terminal bodies with the wiring holes in different directions, thereby reducing the bending amplitude required for connecting part of the terminal body to the wires.

[0008] Furthermore, a board card slot connected to the column socket is provided on one side, and a toggle plate is provided on the positioning column. After the toggle plate is rotated, it is inserted into the board card slot to prevent the positioning column from moving horizontally, prevent the positioning plug from moving arbitrarily due to external force, and cause the fixed combination between the terminal bodies to fail, thereby improving stability during use.

[0009] Furthermore, a first limit plate is provided in the connecting groove. When the first engaging plate rotates in the connecting groove, it is blocked by the first limit plate and its rotation angle is limited within a certain range, thereby preventing excessive rotation between the terminal bodies, making it inconvenient to use them in combination with each other, and also facilitating the terminal bodies to be released from the combination by reverse rotation.

[0010] Further, the connecting column is provided with an inner slot, the opening of the inner slot is provided with a second snap-fitting opening, the connecting sleeve is provided with a sleeve hole matched with the connecting column, the sleeve hole is provided with an inner plug-in column, the inner plug-in column is provided with a second snap-fitting plate, when the connecting sleeve is movably sleeved on the connecting column, the second snap-fitting plate is inserted into the inner slot, after the terminal body rotates, the second snap-fitting plate rotates in the inner slot and is blocked by the second snap-fitting opening to prevent the terminal bodies from being separated in the horizontal direction. The second snap-fitting plate and the second snap-fitting opening form a double snap-fitting fixing structure with the first snap-fitting plate and the first snap-fitting opening, further improving the stability of the connection when the terminal bodies are used in combination.

[0011] Furthermore, a second limit plate is provided on the inner side of the inner slot. During the rotation of the second locking plate in the inner slot, the second limit plate is blocked by the second limit plate and its rotation angle is limited within a certain range. The functions of the second limit plate and the first limit plate and the first locking plate are similar, that is, they prevent the terminal bodies from rotating excessively with respect to each other and facilitate the release of the combination between the terminal bodies.

[0012] The present invention proposes a quick-connect terminal, which has the beneficial effect that after a plurality of terminal bodies are combined and fixed in the horizontal direction by a first clamping plate and a first clamping opening, different terminal bodies rotate relative to each other, and the terminal bodies cooperate with different positioning holes through the positioning pins at the bottom, so that the terminal bodies can be combined and fixed to each other with different wiring holes facing each other, reducing the bending amplitude required for connecting wires on some terminal bodies, thereby improving the stability and reliability of the connection between the terminal body and the wire.

[0022] The technical solution of the present invention will be clearly and completely described below in conjunction with embodiments.

[0023] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work should fall within the scope of protection of this application.

[0024] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so as to describe the embodiments of the present application described herein.

[0025] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0026] In the present application, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inner", "outer", "middle", "vertical", "horizontal", "lateral", "longitudinal" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings. These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0027] like Figure 1-Figure 4 and Figure 7As shown, it is a preferred embodiment of the present invention, a quick-connect terminal, including a terminal body 1, with wiring holes 11 and toggle switches 12 at both ends of the terminal body 1, the wiring holes 11 are inserted with interconnected wires, and the wires are locked in the wiring holes 11 after the toggle switch 12 is pressed. A connecting groove 2 is provided on one side of the terminal body 1, and a connecting sleeve 3 is provided on the other side. A connecting column 22 and a first engaging opening 21 are provided in the connecting groove 2, and a sleeve hole 32 and a first engaging plate 31 are provided on the connecting sleeve 3. The sleeve hole 32 is located at the center of the connecting sleeve 3 and is movably matched with the connecting column 22. The first engaging plate 31 extends from the connecting sleeve 3 in a certain direction and matches with the first engaging opening 21. A plurality of arc-arranged positioning holes 4 are provided at the bottom of the terminal body 1, and a horizontally movable positioning column 5 is provided in one of the positioning holes 4, and the end of the positioning column 5 matches the positioning hole 4.

[0028] like Figure 5 As shown, when two terminal bodies 1 need to be combined with each other, the connection sleeve 3 of one terminal body 1 needs to be inserted into the connection groove 2 of the other terminal body 1. For the convenience of description, the wiring terminal providing the connection groove 2 is referred to as the main terminal, and the wiring terminal providing the connection sleeve 3 is referred to as the auxiliary terminal. The main terminal remains stationary, and the auxiliary terminal moves horizontally, and the first clamping plate 31 on it is inserted into the first clamping opening 21, and the connecting column 22 is inserted into the sleeve hole 32 accordingly, so that the connection sleeve 3 is movably sleeved on the connecting column 22. The auxiliary terminal can rotate relative to the main terminal. After the auxiliary terminal is rotated, the first clamping plate 31 rotates to the inside of the connection groove 2 and is blocked by the first clamping opening 21, so that the two terminal bodies 1 cannot be separated from each other in the horizontal direction. The auxiliary terminal continues to rotate until the positioning column on it is on the same axis as one of the positioning sockets 4 on the main terminal. After the horizontally moving positioning pin 5 is inserted into the positioning socket 4, the terminal bodies 1 are prevented from rotating, that is, the two terminal bodies 1 are combined and fixed with each other. When the terminal body 1 needs to be separated, the positioning pin 5 is horizontally moved until it is disengaged from the positioning hole 4, and the auxiliary terminal is rotated until the first engaging plate 31 is not blocked by the first engaging opening 21, so that the terminal body 1 can be horizontally separated.

[0029] Since there are multiple positioning sockets 4, the positioning pins 5 can cooperate with the positioning sockets 4 at different positions to allow the terminal bodies 1 to be fixedly connected to each other with the plug holes in different directions, so that the terminal bodies 1 can directly connect to wires in different directions without significantly bending the wires, thereby improving the stability of the wire connection. It should be particularly noted that there is an initial matching angle between the first snap plate 31 and the first snap opening 21, which is the angle difference between the directions of the wiring holes 11 between the auxiliary terminal and the main terminal when the auxiliary terminal has not rotated relative to the main terminal. In this embodiment, the angle difference is 90°, that is, the two are in a mutually perpendicular state, and the operator can change the initial matching angle as needed.

[0030] like Figure 3-Figure 4 As shown, in this embodiment, Figure 4 As shown, three positioning arms 41 arranged in an arc are provided at the bottom of the terminal body 1, and a positioning socket 4 is provided on the positioning arm 41. A strip groove 44 and a column socket 42 are also provided on the positioning arm 41 in the middle. One end of the column socket 42 is connected to the positioning socket 4, and the other end passes through the positioning arm 41. The positioning column 5 passes through the positioning socket 4 and is horizontally inserted into the column socket 42; a board slot 43 connected thereto is provided on one side of the column socket 42, as shown in FIG. Figure 6 As shown, the positioning plug 5 is also provided with a toggle plate 51 and an arc plate 52, the arc plate 52 matches the shape of the bottom of the positioning arm 41, and the toggle plate 51 is movably inserted into the strip groove 44. After the toggle plate 51 is pushed to move horizontally in the strip groove 44 and is fully inserted into the positioning socket 4, the toggle plate 51 can be pressed to rotate and insert into the board card groove 43 to prevent the positioning plug 5 from moving horizontally, thereby improving the stability and reliability of the terminal body 1 after being connected to each other. At this time, the arc plate 52 blocks the outside of the board card groove 43.

[0031] Specifically, the positioning arms 41 are arranged at an interval of 30° from each other, and a first limiting plate 25 is provided in the connecting groove 2. During the rotation of the first engaging plate 31 in the connecting groove 2, the first limiting plate 25 blocks the rotation angle thereof and limits the rotation angle thereof to a certain range. In the present embodiment, the first engaging plate 31 is taken as the initial angle when entering the connecting groove 2, and the first limiting plate 25 limits the rotation angle thereof to 0°-120°. The terminal body 1 rotates within this angle range, and the positioning pin 5 can just cooperate with all the positioning sockets 4. In addition, the provision of the first limiting plate 25 also facilitates the operator to quickly rotate the first engaging plate 31 to a state where it is not blocked by the first engaging opening 21, so that the operator can separate the terminal bodies 1 from each other.

[0032] Furthermore, if Figure 1 and Figure 7As shown, an inner slot 23 is provided at the center of the connecting column 22, a second snap-fitting opening 24 is provided at the opening of the inner slot 23, an inner plug-in column 33 is provided in the sleeve hole 32, and a second snap-fitting plate 34 extending to one side is provided on the inner plug-in column 33. In the present embodiment, the extension directions of the first snap-fitting plate 31 and the second snap-fitting plate 34 are perpendicular to each other. After the connecting sleeve 3 is movably sleeved on the connecting column 22, the second snap-fitting plate 34 is inserted into the inner slot 23. After the terminal body 1 is rotated, the second snap-fitting plate 34 rotates to the inner side of the inner slot 23 and is blocked by the second snap-fitting opening 24 to further prevent the terminal bodies 1 from being separated in the horizontal direction.

[0033] A second limiting plate 26 is provided on the inner side of the inner slot 23. When the second engaging plate 34 rotates in the inner slot 23, it is blocked by the second limiting plate 26 and its rotation angle is limited within a certain range. Similarly, in this embodiment, the second limiting plate 26 also limits the rotation angle of the second engaging plate 34 to 0°-120°.

[0034] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
