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 are also called joints and sockets, and generally refer to electrical connectors. That is, devices that connect two active devices to transmit current or signals. The basic performance of connectors can be divided into three categories: mechanical performance, electrical performance, and environmental performance. The mechanical performance of connectors can be called plug-in force in terms of connection function. Plug-in force is divided into insertion force and extraction force (extraction force is also called separation force), and the requirements of the two are different. Electrical performance of connectors The main electrical properties of connectors include contact resistance, insulation resistance, and dielectric strength. Electrical performance of connectors 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 wire harness end and the connector to separate different subdivided wires from each other to avoid interference. Terminal blocks are an accessory product used to achieve electrical connections, and are industrially classified as connectors. With the increasing degree of industrial automation and the increasingly stringent and precise requirements for industrial control, 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 there are more and more types.

[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 a 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 reduce the cost of use.

[0006] The female connector of the patent document with announcement number CN213546626U includes a shell and a plurality of 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 arranged on the shell, the jack is connected to the inner hole, the terminal includes a recess between the front end and the rear end, the recess corresponds to the position of the jack, the locking block can be inserted into the recess through the jack, and since the limiting groove is connected to the outside of the shell, the ear protruding into the limiting groove can be operated by the user 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 is found that the above technical solution has the following technical problems:

[0008] The connector (announcement number: CN219576001 U) and the female connector (publication number: 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 that multiple wire terminals are removed from the inside of the connector at the same time. Removing the locking block (i.e., the form of the female cover) is prone to the problem of multiple terminals falling out at the same time and then being repeatedly installed. Summary of the invention

[0009] In order to overcome the shortcomings of the prior art, the embodiment of the present application provides a connector plug that is convenient for the assembly and disassembly of the wire terminal. By making the plug-in rod B on the linkage plate strip be plugged into the inside of the B part of the connector plug, multiple control boards in a row are independent of each other. When one end of the control board is controlled to rotate around the shaft rod inside the operating slot or in the recessed slot at one end of the control board, the spring sheet can be deformed to release the support of the outer surface of the spring sheet on one end of the upper limit copper sheet B of the wire terminal, so that the wire terminal can pass through the inside of the through slot on the spring sheet, which is convenient for removing and disassembling a single wire terminal and is conducive to 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, and release 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, with strong overall controllability, achieving the technical effect of freely switching between the disassembly of a single wire terminal and the synchronous controlled disassembly of multiple wire terminals.

[0016] Among them, one end of the control board is hingedly connected to the B part of the connector plug through an axis rod, and one end of the wire terminal is inserted into the inside of the A part of the connector plug 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 A part of the connector plug; 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 inside of the 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 a possible implementation, the multiple spring sheets arranged in the upper and lower rows are opposite to each other in pairs 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 between 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 a possible implementation, a supporting rib is integrally formed at the center of one end of the connector plug part A, one end of the two spring sheets facing each other vertically 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 A part of the connector plug is buckled to the inner wall of the B part of the connector plug through the storage groove, so that the plane of the control panel exposed at the operating slot remains parallel to the surface of the B part of the connector plug.

[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.

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 inside of the connector plug B part, they are respectively plugged into a plurality of control boards arranged in a row.

[0024] In one possible implementation, a notch is processed on one end of the connector plug part B away from the connector plug part A.

[0025] The beneficial effects of this application are:

[0026] First, in this solution, by making the plug-in rod B on the linkage strip plugged into the inside of the connector plug B, multiple control boards in a row are independent of each other.

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

[0040] Embodiment 1:

[0041] This embodiment introduces a specific structure of a connector plug that is convenient for disassembly and assembly of wire terminals. Figure 1-Figure 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, a plurality of spring pieces 11 and a wire terminal 2, a plurality of connector plug B parts 3, both side surfaces of one end of the wire terminal 2 are processed with a crimping piece 15 bent from the edge to the center, both side surfaces of the middle part of the wire terminal 2 are formed with a limiting copper sheet A13 protruding from the center to the edge, and the middle part of the wire terminal 2 is formed with a limiting copper sheet B14 bent from the top to the bottom;

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

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

[0044] In addition, in order to fix one end of the plurality of spring sheets 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 supporting rib 12 is integrally formed at the center of one end of the connector plug A part 1, and one end of two spring pieces 11 facing each other up and down is cross-inserted into the inside of the supporting rib 12, so that the two spring pieces 11 facing each other can be arranged in a V shape with the supporting rib 12 as the manufacturing point;

[0045] At the same time, by making the other end of the spring sheet 11 fit and connect to the middle of the control board 7, the spring sheet 11 can be kept in an inclined state (in this state, by processing the 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 part 1 is buckled to the inner wall of the connector plug B part 3 through the receiving groove 17, so that the plane of the control board 7 exposed at the operation slot 5 can be kept parallel to the surface of the connector plug B part 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 and fixed therein, as shown in FIG. Figures 2 to 7 As shown, the plurality of spring pieces 11 are all processed with a through slot 8 inside, and by inserting one end of the wire terminal 2 into the inside of the connector plug A part 1 through the through slot 8, the limiting copper sheet B14 can be supported on the surface of the spring piece 11, limiting the wire terminal 2 from moving in the direction away from the connector plug A part 1 inside the connector plug B part 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 A part 1, which can limit one end of the wire terminal 2 from continuing to extend into the interior of the connector plug A part 1 through the connector plug B part 3, thereby achieving the effect of fixing the wire terminal 2 between the connector plug A part 1 and the connector plug B part 3;

[0048] Next, 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 plurality of spring sheets 11, and one end of the control board 7 is hingedly connected to the connector plug B portion 3 through the shaft 4. When the control board 7 is rotated around the shaft 4, the spring sheet 11 corresponding to the control board 7 is deformed, so that the spring sheet 11 can eliminate the obstruction of one end of the upper limit copper sheet B14 of the wire terminal 2, so that the wire terminal 2 can pass through the inside of the slot opening 8 (in this state, the upper limit copper sheet A13 can also pass through the inside of the slot opening 8);

[0049] At the same time, if Figures 5 to 10 As shown, a row of multiple control boards 7 located at the top and bottom is provided with a same linkage strip 6 at one end. By connecting the linkage strip 6 to one end of the multiple control boards 7 located at the top or bottom, the multiple control boards 7 can be controlled to rotate around the shaft 4 with the linkage strip 6, so that the spring pieces 11 corresponding to the multiple control boards 7 are deformed synchronously, so that the spring pieces 11 eliminate the obstruction of one end of the upper limit copper sheet B14 of the wire terminal 2, so as to facilitate the control of the multiple wire terminals 2 in the same row to pass through the inside of the slot opening 8 of the corresponding spring piece 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 B part 3 are processed with multiple operating slots 5, and the interiors of the multiple operating slots 5 are connected to the interior of the connector plug B part 3, and correspond to the multiple control boards 7 one by one. The surfaces of the middle parts of the multiple control boards 7 are exposed from the interior of the operating slots 5 to the exterior of the connector plug B part 3. By applying pressure to the control board 7 through the operating slots 5, the control board 7 is rotated around the shaft 4, and the deformation degree of the spring 11 is controlled by the control board 7, so that the wire terminal 2 can be withdrawn from the connector plug A part 1 to the inside of the connector plug B part 3, and finally removed (compared with the existing wire terminal dedicated nail remover, no specific tools are required, and the operation is more convenient);

[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 Figure 2 and Fig.10 As shown, one end of the control board 7 is processed with a recessed notch 9. By making the recessed notch 9 located at the end surface of the connector plug B part 3, when one end of the wire terminal 2 is crimped onto the wire through the crimping piece 15, the wire terminal 2 and the wire can be combined together. When the wire terminal 2 is inserted into the inside of the connector plug A part 1 through the connector plug B part 3 and one end of the wire is received inside the connector plug B part 3, the control board 7 can be controlled to rotate around the shaft 4 through the recessed notch 9, so that one end of the control board 7 is close to the wire, thereby deforming the spring sheet 11 with the help of the control board 7, so that the wire terminal 2 can pass through the inside of the through-slot 8 on the spring sheet 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 a plurality of plug-in rods A10;

[0053] By making the linkage strip 6 movably connected to the storage strip groove 17 of a row of control boards 7, when the two plug-in rods B16 are plug-in connected to the inside of the connector plug B part 3, the multiple control boards 7 can be kept to rotate around the shaft rod 4 independently of each other;

[0054] At the same time, when the plurality of plug-in rods A10 are combined in pairs and the two plug-in rods B16 are withdrawn from the connector plug B part 3, the plurality of plug-in rods A10 on one side of the plug-in rod B16 can be respectively plugged into the plurality of control boards 7 in a row, and the plurality of control boards 7 can be linked by a linkage strip 6 to ensure that when one control board 7 is controlled to move around the shaft 4, all the control boards 7 can be synchronously controlled to rotate around the shaft 4, and finally the plurality of spring sheets 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 sheets 11, which greatly facilitates the overall removal of the plurality of wire terminals 2;

[0055] In addition, in order to ensure that the linkage strip 6 links 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 strip 6 and the connector plug B part 3, such as Figure 2 and Fig.10 As shown, a notch is processed on one end of the connector plug part B 3 away from the connector plug part A 1. When 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 connector plug part B 3 will not block the movement of the linkage strips 6.

[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 sheets 11 are arranged in two rows in the connector plug B part 3, and the spring sheets 11 at the top and bottom correspond to each other without missing, and after one end of the multiple spring sheets 11 is connected to the supporting rib 12, the other end thereof abuts against 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 B part 3, and after passing through the slot opening 8 on the spring sheet 11, plug it into the interior of the connector plug A part 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 A part 1, and one end of the limiting copper sheet B14 on the wire terminal 2 is elastically deformed first, passes through the inside of the slot opening 8, and then elastically resets and is supported on the outer surface of the spring sheet 11, which can limit the movement of the wire terminal 2 between the connector plug A part 1 and the connector plug B part 3 toward one end of the connector plug A part 1 and one end of the connector plug B part 3.

[0059] At the same time, when the wire terminal is disassembled using the connector plug that facilitates the disassembly and assembly 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 part 3, and the multiple control boards 7 in a row are independent of each other;

[0061] Approach 1: Apply pressure to the corresponding control board 7 at the operation slot 5, so that the control board 7 rotates around the shaft 4 toward the inside of the connector plug B part 3. During the movement of the control board 7, pressure is applied to one end of the spring sheet 11 by means of the middle part thereof, so that the spring sheet 11 is deformed when the other end is connected to the supporting rib 12, and the support of the outer surface of the spring sheet 11 on one end of the upper limit copper sheet B14 of the wire terminal 2 is released, so that the wire terminal 2 (including the limit copper sheet A13 and the limit copper sheet B14 attached thereto) can pass through the inside of the through slot 8 on the spring sheet 11, and the removal of a single wire terminal 2 can be completed without being restricted by the type of tool;

[0062] Method 2: Find the wire connected to the wire terminal 2 to be removed at one end of the connector plug B part 3, and use the recessed notch 9 to control one end of the control board 7 to rotate around the shaft 4, so that the spring 11 is deformed when the other end is connected to the supporting rib 12, and the outer surface of the spring 11 supports one end of the upper limit copper sheet B14 of the wire terminal 2, so that the wire terminal 2 can pass through the through-slot 8 on the spring 11, and the removal of the single wire terminal 2 can be completed;

[0063] Inside the storage slots 17 on the multiple control boards 7 (in a row), the linkage strips 6 are controlled to move toward one end of the multiple control boards 7, so that the two plugging rods B16 on one side of the linkage strips 6 are withdrawn from the inside of the connector plug B part 3, and the multiple plugging 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 multiple springs 11 to deform, 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: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
