Description

Technical Field

[0001] The invention relates to the technical field of electrical connectors, in particular to a connector plug which is convenient for disassembling and assembling wire terminals. Background Art

[0002] Electrical connectors, also known as headers and sockets, generally refer to electrical connectors. These are devices that connect two active components, transmitting current or signals. The basic performance of connectors can be categorized into three main categories: mechanical, electrical, and environmental. The mechanical performance of connectors, in terms of their connection function, can be referred to as plug-in / pull-out force. This force is divided into insertion force and extraction force (also known as separation force), each with different requirements. The main electrical properties of connectors include contact resistance, insulation resistance, and dielectric strength.

[0003] Taking into account the technological development and actual situation of connectors, connectors can be divided into the following categories based on their versatility and relevant technical standards: low-frequency circular connectors, rectangular connectors, printed circuit connectors, RF coaxial connectors and fiber optic connectors.

[0004] In electrical circuits, wire terminals are often used between the ends of wire harnesses and connectors to separate different sub-wires and prevent interference. Terminal blocks are accessories used to achieve electrical connections and are industrially classified as connectors. With increasing levels of industrial automation and increasingly stringent and precise industrial control requirements, the use of terminal blocks has gradually increased. With the development of the electronics industry, the scope of use of terminal blocks has expanded, and their variety has also increased.

[0005] The patent document with announcement number CN219576001U discloses a connector that limits the female terminal in the female terminal installation groove through a detachably connected female cover and female base. When the female terminal and the male terminal are damaged during long-term plug-in mating, the female cover can be opened for replacement, which is convenient for disassembly and replacement, maintenance and repair, and can also reduce the cost of use.

[0006] The female connector of the patent document with announcement number CN213546626U includes a shell and several terminals, the shell includes an inner hole, the terminal includes a front end and a rear end, and a jack and a locking block are provided on the shell, the jack is connected to the inner hole, the terminal includes a recess located between the front end and the rear end, the recess corresponds to the position of the jack, and the locking block can be inserted into the recess through the jack. Since the limiting groove is connected to the outside of the shell, the ear protruding into the limiting groove can be used by the user to operate to pull out the locking block, thereby ensuring the convenience of terminal disassembly.

[0007] However, in the process of implementing the above technical solution, it was found that the above technical solution had the following technical problems:

[0008] The connector (Announcement No.: CN219576001 U) and the female connector (Publication No.: CN213546626U) both use a locking block similar to a female cover. When the locking block is installed between the wire terminal and the connector body, the connection between the terminal and the connector can be released by removing the locking block. However, in actual application, it is rare for multiple wire terminals to be removed from the inside of the connector at the same time. Removing the locking block (i.e., the form of the female cover) can easily cause multiple terminals to fall out at the same time and then be repeatedly installed. Summary of the Invention

[0009] To overcome the shortcomings of the prior art, the present invention provides a connector plug that facilitates the assembly and disassembly of wire terminals. By placing the plug rod B on the linkage strip in a state of being plugged into the interior of the connector plug B, multiple control boards in a row are made independent of each other. When one end of the control board is controlled to rotate about the shaft within the operating slot or the recessed slot at one end of the control board, the spring plate can be deformed, releasing the support of the outer surface of the spring plate on the end of the upper limit copper plate B of the wire terminal, allowing the wire terminal to pass through the through-slot on the spring plate, thereby facilitating the removal of a single wire terminal and facilitating precise operation.

[0010] By moving the linkage strip toward one end of the multiple control boards, the two plug-in rods B on one side of the linkage strip are withdrawn from the interior of the connector plug B, and the multiple plug-in rods A are respectively plugged into the corresponding control boards, so that the multiple control boards are in a linkage state, and the multiple control boards synchronously control the deformation of the multiple springs, releasing the support of the outer surface of the spring on one end of the upper limit copper sheet B of the wire terminal, so that the multiple wire terminals in the same row can pass through the corresponding slots on the spring, thereby completing the removal and removal of the multiple wire terminals in the same row. The overall controllability is strong, and the technical effect of freely switching between the disassembly of a single wire terminal and the synchronous controlled disassembly of multiple wire terminals is achieved.

[0011] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0013] There are multiple shrapnels arranged in two rows;

[0014] There are multiple wire terminals, which correspond one to one with the multiple springs;

[0015] The two side surfaces of one end of the wire terminal are processed with crimping pieces bent from the edge to the center, the two side surfaces of the middle part of the wire terminal are formed with a limiting copper piece A protruding from the center to the edge, and the middle part of the wire terminal is formed with a limiting copper piece B bent from the top to the bottom; the interiors of the multiple spring pieces are processed with slots, and one end of the multiple spring pieces is provided with a control board, and one end of the multiple control boards in a row at the top and bottom is provided with the same linkage strip;

[0016] Among them, one end of the control board is hingedly connected to the connector plug B part through an axis rod, and one end of the wire terminal is inserted into the interior of the connector plug A part through the slot, so that the limiting copper sheet B is supported on the surface of the spring sheet, and one side of the limiting copper sheet A is supported on the surface of one end of the connector plug A part; the control board rotates around the axis rod, so that the spring sheet corresponding to the control board is deformed, and the limiting copper sheet B in the middle of the wire terminal passes through the interior of the slotted slot, and the linkage strip is connected to one end of multiple control boards located at the top or bottom, controlling the multiple control boards to rotate around the axis rod, so that the spring sheets corresponding to the multiple control boards are deformed synchronously.

[0017] In one possible implementation, the multiple spring sheets arranged in the upper and lower rows are opposite each other and form a V-shape inside the connector plug part B. The ends of the two spring sheets that are close to each other in the facing state are arranged at the connection point of the connector plug part A and the connector plug part B, and the ends that are away from each other are arranged at the end of the connector plug part B away from the connector plug part A.

[0018] In one possible implementation, a supporting rib is integrally formed at the center of one end of the connector plug part A, and one end of the two spring sheets facing each other are cross-plugged into the interior of the supporting rib, and the other end of the spring sheet is adapted to be connected to the middle of the control board to maintain the tilted state of the spring sheet.

[0019] In one possible implementation, the top and bottom of the connector plug part B are processed with multiple operating slots, the interiors of the multiple operating slots are connected to the interior of the connector plug part B, and correspond one-to-one to the multiple control boards, and the surfaces of the middle parts of the multiple control boards are exposed from the interior of the operating slots to the outside of the connector plug part B.

[0020] In one possible implementation, a storage groove is processed on the surface of one end of each of the control panels, and the end of the control panel away from the connector plug part A is snapped onto the inner wall of the connector plug part B through the storage groove, so that the plane of the control panel exposed at the operating slot remains parallel to the surface of the connector plug part B.

[0021] In a possible implementation, an inward-recessed notch is processed at one end of the control board, and the inward-recessed notch is located at the end surface of the connector plug portion B.

[0022] In one possible implementation, both ends of one side of the linkage slat are integrally formed with a plug-in rod B, and the surface of the other side of the linkage slat is integrally formed with multiple plug-in rods A. The linkage slat is movably connected to the inside of a storage slot of a row of control panels, and the two plug-in rods B are plug-connected to the inside of the connector plug B.

[0023] In a possible implementation, a plurality of the plug-in rods A are combined in pairs, and when two plug-in rods B are withdrawn from the interior of the connector plug B, they are respectively plugged into a plurality of control boards arranged in a row.

[0024] In one possible implementation, a notch is machined on one end of the connector plug part B away from the connector plug part A. When the two linkage strips are connected to the connector plug part B, they are respectively located at the two openings to form a blockage, and when connected to multiple control boards in a row, they are movably connected to the notch.

[0025] The beneficial effects of this application are:

[0026] First, in this solution, by making the plug-in rod B on the linkage strip be plugged into the interior of the connector plug B, multiple control boards in a row are made independent of each other. When one end of the control board is controlled to rotate around the shaft rod inside the operating slot or the recessed slot at one end of the control board, the spring piece can be deformed, releasing the support of the outer surface of the spring piece on one end of the upper limit copper piece B of the wire terminal, so that the wire terminal can pass through the through-slot on the spring piece, facilitating the removal of a single wire terminal and facilitating precise operation.

[0027] Secondly, in this solution, by moving the linkage strip toward one end of the multiple control boards, the two plug-in rods B on one side of the linkage strip are withdrawn from the interior of the connector plug B, and the multiple plug-in rods A are respectively plugged into the corresponding control boards, so that the multiple control boards are in a linkage state, and the multiple control boards synchronously control the deformation of the multiple springs, thereby releasing the support of the outer surface of the spring on one end of the upper limit copper sheet B on the wire terminal, so that the multiple wire terminals in the same row can pass through the corresponding slots on the spring, thereby completing the removal and removal of the multiple wire terminals in the same row, and the overall controllability is strong.

[0039] The technical solution in the embodiments of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0040] Example 1:

[0041] This embodiment introduces a specific structure of a connector plug that is convenient for assembling and disassembling wire terminals. Figures 1-10As shown, it includes a connector plug A part 1, a connector plug B part 3 integrally formed at one end of the connector plug A part 1, multiple springs 11 and a wire terminal 2, multiple connector plug B parts 3, both sides of the surface of one end of the wire terminal 2 are processed with a crimping piece 15 bent from the edge to the center, both sides of the middle part of the wire terminal 2 are formed with a limiting copper piece A13 protruding from the center to the edge, and the middle part of the wire terminal 2 is formed with a limiting copper piece B14 bent from the top to the bottom;

[0042] Among them, regarding the arrangement of multiple springs 11 and multiple control boards 7, as shown in FIG. Figures 2 to 7 As shown, the multiple spring pieces 11 are arranged in two rows, one above the other, and the multiple control boards 7 correspond one to one with the multiple spring pieces 11 and are respectively located at one end of the spring pieces 11;

[0043] At the same time, the multiple spring pieces 11 arranged in the upper and lower rows are opposite each other in pairs and form a V-shape inside the connector plug portion B 3 (the ends of the two spring pieces 11 facing each other are arranged at the connection point of the connector plug portion A 1 and the connector plug portion B 3, and the ends away from each other are located at the end of the connector plug portion B 3 away from the connector plug portion A 1);

[0044] In addition, in order to fix one end of the plurality of spring pieces 11 in two rows between the connector plug A part 1 and the connector plug B part 3, as shown in FIG. Figure 3 、 Figure 7 and Figure 8 As shown, a support rib 12 is integrally formed at the center of one end of the connector plug part A 1. By cross-plugging one end of two spring pieces 11 facing each other into the interior of the support rib 12, the two spring pieces 11 facing each other can be arranged in a V-shape with the support rib 12 as the manufacturing point.

[0045] At the same time, by fitting the other end of the spring plate 11 to the middle portion of the control board 7, the spring plate 11 can be maintained in an inclined state (in this state, by forming a receiving groove 17 on the surface of one end of the plurality of control boards 7, the end of the control board 7 away from the connector plug A portion 1 is fastened to the inner wall of the connector plug B portion 3 through the receiving groove 17, so that the surface of the control board 7 exposed at the operating notch 5 can remain parallel to the surface of the connector plug B portion 3).

[0046] Secondly, regarding the manner and state in which the plurality of wire terminals 2 are inserted into the connector plug part A 1 through the connector plug part B 3, as shown in FIG. Figures 2 to 7 As shown, the interiors of the multiple spring pieces 11 are each machined with a through-slot 8. By inserting one end of the wire terminal 2 into the interior of the connector plug A portion 1 through the through-slot 8, the limiting copper sheet B14 can be supported on the surface of the spring piece 11, thereby limiting the movement of the wire terminal 2 in the direction away from the connector plug A portion 1 within the connector plug B portion 3.

[0047] At the same time, one side of the limiting copper sheet A13 is supported on the surface of one end of the connector plug portion A1, which can restrict one end of the wire terminal 2 from continuing to extend into the interior of the connector plug portion A1 through the connector plug portion B3, thereby achieving the effect of fixing the wire terminal 2 between the connector plug portion A1 and the connector plug portion B3;

[0048] Furthermore, regarding the removal operation after the lead terminal 2 is inserted into the connector plug part A 1 through the connector plug part B 3 and locked by the spring 11, as shown in FIG. Figures 1 to 3 、 Figures 5 to 7 As shown, a control board 7 is provided at one end of each of the multiple spring plates 11. One end of the control board 7 is hingedly connected to the connector plug portion B 3 via a shaft 4. When the control board 7 rotates about the shaft 4, the spring plate 11 corresponding to the control board 7 is deformed, which allows the spring plate 11 to eliminate the obstruction of one end of the upper limit copper plate B14 of the wire terminal 2, allowing the wire terminal 2 to pass through the interior of the slot 8 (in this state, the upper limit copper plate A13 can also pass through the interior of the slot 8);

[0049] At the same time, if Figures 5 to 10 As shown, a plurality of control boards 7 in a row at the top and bottom are provided with a same linkage strip 6 at one end. By connecting the linkage strip 6 to one end of the plurality of control boards 7 at the top or bottom, the linkage strip 6 can be used to control the plurality of control boards 7 to rotate around the shaft 4, causing the spring pieces 11 corresponding to the plurality of control boards 7 to deform synchronously, so that the spring pieces 11 eliminate the obstruction of one end of the upper limit copper piece B14 of the wire terminal 2, thereby facilitating the control of the plurality of wire terminals 2 in the same row through the slots 8 of the corresponding spring pieces 11.

[0050] Furthermore, in order to facilitate the control of the control board 7 to rotate around the shaft 4, the support control board 7 applies pressure to one end of the spring 11 to cause deformation, thereby eliminating the obstruction of the spring 11 to the upper limit copper sheet B14 of the wire terminal 2. Figure 2 、 Figure 3 and Figure 7 As shown, the top and bottom of the connector plug portion B 3 are machined with multiple operating notches 5. The interiors of the multiple operating notches 5 are connected to the interior of the connector plug portion B 3 and correspond one-to-one with the multiple control boards 7. The central surfaces of the multiple control boards 7 are exposed from the interior of the operating notches 5 to the exterior of the connector plug portion B 3. By applying pressure to the control board 7 through the operating notches 5, the control board 7 rotates about the shaft 4, and the control board 7 controls the deformation of the spring 11, so that the wire terminal 2 can be withdrawn from the connector plug portion A 1 to the interior of the connector plug portion B 3 and ultimately removed. (Compared to existing dedicated wire terminal removers, this does not require the use of special tools and is more convenient to operate.)

[0051] At the same time, in order to optimize the control mode of the control board 7 rotating around the shaft 4 to the greatest extent, as shown in FIG. Figure 2 and Figure 10 As shown, one end of the control board 7 is machined with a recessed notch 9. By locating the recessed notch 9 at the end surface of the connector plug portion B 3, when one end of the wire terminal 2 is crimped onto the wire via the crimping piece 15, the wire terminal 2 and the wire can be combined. When the wire terminal 2 is inserted into the interior of the connector plug portion A 1 via the connector plug portion B 3, so that one end of the wire is received within the connector plug portion B 3, the control board 7 can be controlled to rotate about the shaft 4 via the recessed notch 9, so that one end of the control board 7 approaches the wire, thereby deforming the spring 11 with the help of the control board 7, allowing the wire terminal 2 to pass through the interior of the through-slot 8 on the spring 11.

[0052] In some examples, both ends of one side of the linkage slat 6 are integrally formed with plug-in rods B16, and the surface of the other side of the linkage slat 6 is integrally formed with multiple plug-in rods A10;

[0053] The linkage strips 6 are movably connected to the storage slots 17 of a row of control boards 7. When both plug-in rods B16 are plug-connected to the inside of the connector plug B part 3, the multiple control boards 7 can be kept rotating independently around the shaft 4.

[0054] At the same time, when the multiple plug rods A10 are combined in pairs and the two plug rods B16 are withdrawn from the connector plug B part 3, the multiple plug rods A10 on one side of the plug rod B16 can be respectively plugged into the multiple control boards 7 in a row. With the help of a linkage strip 6, the multiple control boards 7 are linked to ensure that when controlling the movement of one control board 7 around the shaft 4, all the control boards 7 can be synchronously controlled to rotate around the shaft 4, and finally the multiple spring plates 11 in a row are synchronously deformed, so that the corresponding row of wire terminals 2 can be withdrawn from the slots 8 of the corresponding spring plates 11, which greatly facilitates the overall removal of the multiple wire terminals 2.

[0055] In addition, in order to ensure that the linkage strips 6 link the multiple control boards 7, the control boards 7 can be controlled to rotate around the shaft 4, and there will be no interference between the linkage strips 6 and the connector plug B part 3, such as Figure 2 and Figure 10 As shown, the end of the connector plug part B 3 away from the connector plug part A 1 is processed with a notch. When the two linkage strips 6 are connected to the connector plug part B 3, they are respectively located at the two openings to form a blockage to ensure the beautiful appearance of one end of the connector plug part B 3. When the linkage strips 6 are connected to multiple control boards 7 in a row, they can be movably connected to the notch, and the situation where the connector plug part B 3 blocks the movement of the linkage strips 6 will not occur.

[0056] Specifically, when the connector plug that facilitates the disassembly and assembly of the wire terminal is used to install the wire terminal:

[0057] First, ensure that the multiple spring clips 11 are arranged in two rows inside the connector plug B portion 3, and that the spring clips 11 at the top and bottom correspond to each other without any gaps. After one end of the multiple spring clips 11 is connected to the support rib 12, the other end rests on the middle of the control board 7 without any looseness.

[0058] Then, select a wire with a wire terminal 2, insert the wire terminal 2 into the interior of the connector plug part B 3, and after passing through the slot 8 on the spring piece 11, plug it into the interior of the connector plug part A 1, so that the limiting copper sheet A13 on the wire terminal 2 is supported on the surface of one end of the connector plug part A 1, and one end of the limiting copper sheet B14 on the wire terminal 2 is first elastically deformed, passes through the interior of the slot 8, and then elastically reset and supported on the outer surface of the spring piece 11, which can limit the movement of the wire terminal 2 between the connector plug part A 1 and the connector plug part B 3 toward one end of the connector plug part A 1 and one end of the connector plug part B 3.

[0059] At the same time, when the wire terminal is disassembled using the connector plug that facilitates the disassembly of the wire terminal:

[0060] The plug-in rods B16 at both ends of one side of the linkage strip 6 are in a state of being plugged into the interior of the connector plug B portion 3, and the multiple control boards 7 in a row are independent of each other;

[0061] Method 1: Apply pressure to the corresponding control board 7 at the operating slot 5, causing the control board 7 to rotate about the shaft 4 toward the interior of the connector plug portion B 3. During this movement, the control board 7 applies pressure to one end of the spring plate 11 through its center, causing the spring plate 11 to deform while the other end is connected to the supporting rib 12. This releases the support of the outer surface of the spring plate 11 on one end of the limiting copper plate B14 of the wire terminal 2, allowing the wire terminal 2 (including the limiting copper plates A13 and B14 attached thereto) to pass through the slot 8 of the spring plate 11. This allows the removal of a single wire terminal 2 to be completed without being restricted by the type of tool used.

[0062] Method 2: At one end of connector plug portion B 3, locate the wire connected to the wire terminal 2 to be removed. Using the recessed notch 9, one end of the control board 7 is rotated about the shaft 4, causing the spring 11, while its other end is connected to the support rib 12, to deform. This releases the outer surface of the spring 11 from supporting the upper limit copper plate B14 of the wire terminal 2, allowing the wire terminal 2 to pass through the through-slot 8 in the spring 11, thus completing the removal of the single wire terminal 2.

[0063] Inside the storage slots 17 on the multiple control boards 7 (in a row), the control linkage strip 6 moves toward one end of the multiple control boards 7, so that the two plug rods B16 on one side of the linkage strip 6 are withdrawn from the inside of the connector plug B part 3, and the multiple plug rods A10 are respectively plugged into the corresponding control boards 7, so that the multiple control boards 7 are in a linkage state;

[0064] Approach three: Control one side of the linkage strip 6 so that the linkage strip 6 drives one end of the multiple control boards 7 to move. When the linkage strip 6 moves at the notch at one end of the connector plug B part 3, the multiple control boards 7 rotate synchronously, so that the multiple control boards 7 synchronously control the deformation of the multiple springs 11, and release the support of the outer surface of the spring 11 on one end of the upper limit copper sheet B14 of the wire terminal 2, so that the multiple wire terminals 2 in the same row can pass through the corresponding slots 8 on the spring 11, thereby completing the removal and removal of the multiple wire terminals 2 in the same row, and the overall controllability is strong.

[0065] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all embodiments. However, obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
