Description

Technical Field

[0001] This utility model relates to the field of terminal block unit technology, and more specifically to a novel terminal block unit. Background Technology

[0002] Currently, terminal blocks are accessories or devices used to achieve electrical connections, primarily for bridging disconnected circuits or between isolated circuits. Quick-connect terminals, by featuring plug ports with clamping devices, quickly lock inserted wires in place using a clamping mechanism, enabling convenient and reliable wire insertion and connection. This ensures both ease and efficiency in wire insertion while maintaining the stability of the electrical connection.

[0003] However, the existing technologies mentioned above still have some drawbacks. Currently, terminal blocks mainly adopt two types of plug-in structures: push-button type and rocker arm type. Among them, the rocker arm type plug-in interface can balance convenient operation and stable clamping through the set rotating arm. However, due to the limitations of the mechanical structure, existing products can only deploy a maximum of two rocker arm type plug-in interfaces in a single terminal unit. When used in integrated applications, in order to improve space utilization, multiple push-button interfaces with weaker clamping force must be used. In vibration scenarios such as transportation and heavy equipment, push-button interfaces are prone to faults such as increased resistance and instantaneous circuit breakage due to vibration when connecting wires. This not only affects the stability of equipment operation but also requires frequent shutdowns for maintenance, significantly increasing operation and maintenance costs. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the present invention provides a novel terminal block unit.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a terminal body, which is provided with a series groove A for connecting other terminals in series. The terminal body is also provided with a corresponding terminal socket. The terminal socket includes a housing, a plug-in conductive sheet, and several wiring units. A series foot extends below the housing, connecting to the inner cavity of the housing. The series foot is adapted to the series groove A. The plug-in conductive sheet is bent downwards and extends along the series foot. The conductive sheet inside the terminal body is provided with a connection port A that matches the plug-in conductive sheet. The wiring unit includes a plug interface, an operating arm, and a contact piece. The contact piece abuts against the plug-in conductive sheet, and the operating arm can hook the contact piece away from the conductive sheet.

[0006] The present invention is further configured such that: the conductive sheet is located near the middle of the housing, dividing the inner cavity of the housing into two symmetrical contact cavities, the contact cavities being used to set the wiring unit.

[0007] The present invention is further configured such that: the insertion interface is arranged on the upper end face of the housing, and its position matches the contact cavity; and the operating arm is close to the side of the housing.

[0008] The present invention is further configured such that: a limiting protrusion is provided on the back of the housing, and a limiting groove is provided on the housing accordingly.

[0009] The present invention is further configured such that: the terminal socket is provided with a series groove B, and the plug-in conductive sheet is provided with a connection port B adapted to the series groove B.

[0010] The present invention is further configured such that: the number of series slots A is two, and the number of series feet is two.

[0011] This utility model has the following beneficial effects: by forming a cooperation between the series pin and the series slot A, it ensures good contact between the plug-in conductive sheet and the internal conductive sheet of the terminal body, so that the wiring unit with the operating arm set in the terminal socket is connected in series with each wiring unit of the terminal body. This allows multiple wiring units with operating arms to be deployed on one side of the utility model at the same time, so that the wire connection can obtain a more stable connection state, reduce the occurrence of faults, and reduce the maintenance burden.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] This embodiment discloses a novel terminal block unit, such as Figures 1 to 3The diagram shows a terminal body 1, which has a series groove A11 for connecting other terminals in series. The terminal body 1 also has a corresponding terminal socket 2, which includes a housing 21, a conductive insert 22, and several wiring units 24. A series foot 211 extends below the housing 21, connecting to the inner cavity of the housing 21. The series foot 211 is adapted to the series groove A11. The conductive insert 22 is bent downwards and extends along the series foot 211. The conductive insert inside the terminal body 1 has a connection port A12 that matches the conductive insert 22. The connecting pin 211 and the series slot A11 can form a good plug-in fit. At this time, the plug-in conductive piece 22 can fit with the conductive connection port A12 inside the terminal body 1, so that the terminal body 1 and the terminal socket 2 form a good series relationship. The wiring unit 24 includes a plug interface 241, an operating arm 242, and a contact piece 243. The contact piece 243 abuts against the plug-in conductive piece 22. The operating arm 242 can hook the contact piece 243 away from the conductive piece, so that the wire can be easily inserted when wiring. Reversing the operating arm 242 will stably press the inserted wire.

[0020] like Figure 3 As shown, the conductive sheet, located near the center of the housing 21, divides the inner cavity of the housing 21 into two symmetrical contact cavities 23. These contact cavities 23 are used to house the wiring units 24. The symmetrical contact cavities 23 allow the terminal socket 2 to simultaneously accommodate two sets of wiring units 24. This allows for the connection of more wires within a limited space, significantly improving space utilization.

[0021] Further improvements include the insertion interface 241 being located on the upper surface of the housing 21, its position matching that of the contact cavity 23, and the operating arm 242 being located near the side of the housing 21. The contact opening on the upper surface of the housing 21 allows for vertical connection of wires, resulting in high wiring efficiency; and the wiring area on the upper surface of the housing 21 away from the terminal body 1 is separated in the spatial area, facilitating the differentiation of wiring situations, aiding in wiring planning, and avoiding cross-contamination.

[0022] like Figures 4 to 5 As shown, the back of the housing 21 is provided with a limiting protrusion 212, and the housing 21 is correspondingly provided with a limiting groove 213. When the terminal bodies 1 are stacked, the terminal sockets 2 are also stacked. The limiting groove 213 and the limiting protrusion 212 can cooperate with each other to precisely engage and form a physical limit, preventing lateral sliding between the terminal sockets 2 during stacking. At the same time, the limiting groove 213 and the limiting protrusion 212 achieve self-alignment by cooperating with each other in the stacked state, reducing manual adjustment time.

[0023] like Figure 3As shown, the terminal socket 2 is provided with a series groove B25, and the plug-in conductive piece 22 is provided with a connection port B251 adapted to the series groove B25. The series groove B25 is combined with a matching series busbar, so that the connection port B251 is electrically connected to the series teeth of the series busbar, thereby realizing the series connection between different terminal sockets 2.

[0024] like Figure 2 As shown, there are two series grooves A11 and two series feet 211. The two series grooves A11 and series feet 211 can form a double-fit relationship, which can effectively resist rotational or torsional loads, improve the rigidity of the overall structure, and the double fit can compensate for manufacturing tolerances to a certain extent, reducing the requirements for the machining accuracy of individual series feet 211.

[0025] Working principle of this utility model

[0026] During assembly, the terminal body 1 and terminal socket 2 are stacked neatly, and then the serial pins 211 of the stacked terminal socket 2 are inserted into the serial slot A11. The plug-in conductive sheet 22 will form a good electrical connection with the conductive sheet in the terminal body 1. The serial busbar is combined with the serial slot B25, and the stacked terminal units will be connected in series with each other through the serial busbar.

[0027] In use, rotating the operating arm 242 of the terminal socket 2 will loosen the contact piece 243 of the contact opening, making it easy to insert the wire when wiring. Reversing the operating arm 242 will press the contact piece 243 firmly against the inserted wire, making the wiring secure and reliable.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
