Description

Technical Field

[0001] The utility model relates to the field of electronic components, in particular to a wiring terminal assembly. Background Art

[0002] A terminal block is a device used to connect wires, which usually contains a metal head and a fixing nut. The main function of a terminal block is to connect wires to electrical equipment or circuits in order to pass current.

[0003] In view of the diversity of copper cores of wires, there are copper cores composed of multiple copper wires, and there are also single copper core wires. Since there is only one copper core, the single copper core wire is relatively hard. In the process of fixing the wire, it is necessary to consider the high fit between the terminal and the copper core in order to achieve a more stable fixation. In addition, since the size of multiple copper wires is small and the mobility is greater, similar to the single copper core wire, it is also necessary to consider the high fit between the terminal and the communication to ensure good connectivity of the circuit. For this reason, we propose a terminal block assembly. Utility Model Content

[0033] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] In order to address the shortcomings of the existing technology, such as Figure 2 , 3 As shown, the utility model provides a terminal block assembly, in which a connector 2 is insulated and fixedly connected to the inside of a housing 1 .

[0035] It should be noted that in the process of connecting the wires, the connector 2 is adaptively adjusted depending on the type of wire to be connected, whether it is a whole copper core or a copper core composed of several copper wires. After the connector 2 is adjusted to adapt to the type of copper core of the current wire to be connected, the copper core of the wire is then inserted into the interior of the connector 2, and then the copper core of the wire is fixed to the connector 2 by screws 3.

[0036] Specifically, Figure 4As shown, a connector 2 for a terminal assembly includes a base 21, and four pressing blocks 22 movably connected thereto are arranged inside the base 21 for flipping the pressing blocks 22 to change the crimping state of the pressing blocks 22 on the copper core. The four pressing blocks 22 are distributed on the left and right sides of the base 21 in groups of two.

[0037] It should be noted that the utility model is a terminal block assembly, which is provided with a connector 2. During the process of adjusting the connection state of the connector 2, two pressing blocks 22 are rotated inside the base 21 so that the two pressing blocks 22 are suitable for facing one side of the copper core of the current wire to be connected.

[0038] Among them, two pressing blocks 22 are adjusted inside the base 21. The two pressing blocks 22 can select a suitable crimping method according to the type of copper core of the wire to be connected, such as a whole copper core wire or a copper core composed of multiple copper wires.

[0039] Furthermore, if Figure 1 , 5 As shown, a base 21 in a connector 2 for a terminal block assembly, a fitting groove 1 222 and a fitting groove 223 are distributed at the upper and lower ends of the base block 221, a connecting block 224 is fixedly connected to the center of the tail end of the base block 221, or is integrally formed by the base block 221, and a stopper 225 is formed at the inner end of one side of the base block 221 on which the fitting groove 1 222 is formed.

[0040] Furthermore, if Figure 1 , 6 As shown, a pressing block 22 in a connecting piece 2 for a terminal assembly, a slide groove 212 is provided in the middle of one side where the conductive seat 211 is connected with the connecting block 224, and two rotation grooves 213 are respectively provided by upper and lower side sections of the slide groove 212;

[0041] The thread groove 214 is threadably connected to the screw 3 .

[0042] It should be noted that the utility model is a terminal block assembly, which is provided with a base 21 and a pressure block 22. During the process of adjusting the state of the base 21, the base block 221 is slid inside the conductive seat 211, and the base block 221 is moved to the inside of the rotating groove 213 where the connecting block 224 attached thereto is located. In this state, the base block 221 can be rotated inside the conductive seat 211 through the connecting block 224 and based on the corresponding rotating groove 213. After the base block 221 is rotated 180°, the clamping surface of the base block 221 can be replaced.

[0043] Then, the copper core of the wire to be connected is inserted into the inner side of the two base blocks 221. If the entire copper core is to be clamped, the two base blocks 221 are in a state where the two first fitting grooves 222 attached thereto are opposite to each other. If the copper wire is to be clamped, the two second fitting grooves 223 attached thereto are opposite to each other.

[0044] When the copper core of the wire to be connected is located between the two base blocks 221, the screw 3 can be screwed in based on the threaded groove 214 to press the screw 3 onto one of the base blocks 221 located above. During the pressing process, the two base blocks 221 slide inside the slide groove 212 based on the connecting blocks 224 attached thereto. When the screw 3 is tightened, the two base blocks 221 are indirectly pressed and fixed to the wire to be connected.

[0045] As a preferred embodiment, limiting balls 224-1 are provided on both sides of the connecting block 224 that are attached to the slide groove 212, and a limiting slide groove 212-1 is provided on the inner side of the slide groove 212 corresponding thereto, so that the limiting slide groove 212-1 and the limiting ball 224-1 are combined to limit the sliding of the connecting block 224 and the conductive seat 211, so as to avoid the connecting block 224 from falling off in the axial direction during the sliding process, and indirectly affecting the pressing of the copper core.

[0046] The structure of the second fitting groove 223 is opened with reference to the conventional size of the copper wire, while the first fitting groove 222 is opened with reference to the size of the entire copper core, so that the structure of the base block 221 can be matched to the size of the copper core of the wire to be connected to the greatest extent, indirectly ensuring the fastening stability of the two base blocks 221 to the copper core of the wire to be connected;

[0047] The stopper 225 serves to block the copper core of the wire, and can better fix the wire during the crimping process of the copper core of the wire, thereby ensuring the maximum contact stability between the copper core of the wire and the two base blocks 221.

[0048] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
