Description

Technical Field

[0001] This utility model relates to the field of signal adapter box technology, specifically a modular conductive and insulated signal adapter box structure. Background Technology

[0002] A signal transfer box is a device that leads electrical signals to a test panel. Signal transfer boxes are enclosures used for the centralized management, distribution, or transfer of various signals (such as electrical signals, optical signals, network signals, etc.), and are commonly found in fields such as communications, power, transportation, and security.

[0003] A continuity-insulated signal adapter box is a specially designed signal transfer device primarily used to achieve electrical isolation or insulation while ensuring signal conduction, preventing signal distortion or equipment damage caused by interference, grounding loops, or potential differences. It is widely used in power systems, rail transportation, industrial automation, and other fields, and is particularly crucial in high-voltage, high-electromagnetic-interference (EMI) scenarios or those requiring safe isolation. However, traditional continuity-insulated signal adapter boxes typically lack modular design, making it difficult to lock and fix multiple boxes together according to requirements, and thus unable to flexibly adapt to different scenarios. Utility Model Content

[0004] The purpose of this invention is to provide a modular conductive and insulated signal transfer box structure, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular conductive insulated signal transfer box structure, including a transfer box body, wherein a passive locking member and a main body locking member are provided on the side of the transfer box body, and the passive locking member is located below the active locking member.

[0006] The passive locking component includes a locking block, which is fixed to the main body of the adapter box. A slot is provided on the top of the locking block, and a locking screw hole is provided in the middle of the locking block. The slot and locking screw hole are used to cooperate with the active locking component to fix two or more adapter box main bodies together.

[0007] The active locking component includes a hinge base, a hinge shaft rotatably connected to the inner side of the hinge base, a positioning plate fixed on the hinge shaft, a locking block that mates with a locking slot fixed at the top of the positioning plate, and a positioning hole that mates with a locking screw hole near the positioning block. The positioning hole and the locking screw hole are aligned and fixed together by bolts. The two adapter box bodies are fixed together by bolts for easy disassembly and assembly later.

[0008] As a preferred embodiment of this utility model, a mounting plate is fixed on the side of the adapter box body near the front. The mounting plate has mounting holes and is used to fix the adapter box body in a specific position with screws.

[0009] As a preferred embodiment of this utility model, a handle is fixed on the mounting plate, and the handle is mainly for the convenience of picking up the main body of the adapter box.

[0010] As a preferred embodiment of this utility model, the locking block and the adapter box body, as well as the hinge seat and the adapter box body, are all detachably installed to facilitate disassembly and assembly and allow for flexible use.

[0011] As a preferred embodiment of this invention, the back of the adapter box body is provided with a cascading expansion connection port. This cascading expansion connection port allows for the connection of several adapter box bodies, enabling the equipment to be cascaded by connecting the instrument ports on the rear panel, thus achieving equipment scalability.

[0012] In a preferred embodiment of this invention, the adapter box body is equipped with a first insulation signal and a second insulation signal. The first insulation signal is located near the front of the adapter box body, and the second insulation signal is located near the back of the adapter box body. The first insulation signal is an "insulation +" signal, and the second insulation signal is an "insulation -" signal. This improves the insulation between positive and negative signals during insulation testing and physically isolates them during the design phase.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention employs a dual locking design with both active and passive components. The passive locking component includes a locking block with a slot and a locking screw hole, while the active locking component drives the locking block and positioning hole via a hinge shaft, achieving rapid alignment and bolt fixing. All locking components are detachable, supporting multi-box stacking assembly to meet flexible disassembly and assembly needs. This enhances the overall quality of the device.
