Description

Technical Field

[0001] This utility model belongs to the field of wire harness module technology, and particularly relates to medical centrifuge wire harness module. Background Technology

[0002] Medical centrifuge wiring harness modules are electrical connection components specifically designed for medical testing equipment (such as blood centrifuges and pathology sample separators). Their core function is to establish circuitry between the centrifuge main unit and external power supplies, control modules, sensors, and other components. Through mechanical fixation and protection, they ensure stable operation of the equipment under high-speed rotation conditions. These modules typically consist of sockets, plugs, conductive lines, and protective structures. Their reliability directly affects the centrifuge's separation accuracy and safety, making them a critical foundational component of medical equipment electrical systems.

[0003] However, existing medical centrifuge wiring harness modules have the following drawbacks in actual use: Firstly, they employ a plug-in connection structure, relying on elastic clips or friction to secure the plug and socket. However, the high-frequency vibrations generated during centrifuge operation can cause the plug and socket to gradually loosen. Furthermore, the elastic clips are prone to plastic deformation under prolonged stress, leading to increased contact resistance and circuit interruptions. Secondly, the power transmission lines and conductive posts in existing medical centrifuge wiring harness modules often use rigid connections such as welding or crimping. When a single line fails due to aging or external damage, the entire wiring harness module must be disassembled or even replaced. Additionally, the integral rubber sheath on the outside of the lines requires damage for repair, making it difficult to restore sealing performance.

[0004] Therefore, it is essential to invent a medical centrifuge wiring harness module. Utility Model Content

[0005] To address the above problems, this utility model proposes a medical centrifuge wiring harness module, and the technical solution used is as follows:

[0006] A medical centrifuge wiring harness module includes a socket, conductive lines, a plug, conductive posts, a locking mechanism, a terminal block, a power transmission line, and a sealing strip. Both ends of the power transmission line are electrically connected to corresponding terminal blocks, and the outer surface of the power transmission line is wrapped with a sealing strip, the two ends of which are fixed to corresponding plugs. The terminal blocks are fixed to corresponding plugs. One end of each plug is fixed with a conductive post, which is electrically connected to the corresponding terminal port of the terminal block via a data cable. A locking mechanism is rotatably mounted on the outer surface of the plug, and the socket has a locking hole adapted to the locking mechanism. The socket is fixed to the corresponding position of the medical centrifuge housing by bolts, and the socket is electrically connected to the corresponding electrical components of the medical centrifuge via the conductive lines. A conductive sleeve is fixed on the conductive line inside the socket, the inner diameter of which is the same as the diameter of the conductive post. The socket has a groove corresponding to the plug. Both the conductive lines and the power transmission line consist of a conductor and an insulating layer, with the conductor fixed inside the insulating layer.

[0007] Furthermore, the locking mechanism includes a turntable, a locking cylinder, and a handle. The turntable is rotatably mounted on the outer side of the plug, and the locking cylinder is integrally formed on the side of the turntable. The locking cylinder is connected to the locking hole on the socket by thread engagement. The handle is fixed on the side of the turntable away from the locking cylinder. This arrangement can prevent the plug from detaching from the socket (medical centrifuges will generate a certain degree of vibration during operation).

[0008] Furthermore, the connector includes a base body, a conductive plate, a pressure plate, and screws. The base body is fixed to the plug by bolts, and a pressure plate is slidably installed inside the base body. The upper side of the pressure plate is rotatably connected to the screw, which passes through the base body through thread engagement. Conductive plates are fixed to the lower side of the pressure plate and the inner wall of the base body below the pressure plate. The conductive plates are electrically connected to the conductive posts through data lines. A sealing strip is fixed on the base body. This configuration allows the power line to be electrically connected to the plug when the power line is damaged, and allows the power line to be separated from the plug when needed.

[0009] Furthermore, the sealing strip includes an upper strip body, a lower strip body, a groove, a locking block, and a locking slot. The lower side of the upper strip body and the upper side of the lower strip body are fitted together, and both the lower side of the upper strip body and the upper side of the lower strip body are provided with corresponding grooves, each groove containing a power transmission line. Several locking blocks are fixed to the lower side of the upper strip body, and several locking slots corresponding to the locking blocks are provided on the upper side of the lower strip body. Both ends of the upper and lower strip bodies are fixed to corresponding terminal blocks. This arrangement can seal the power transmission line and facilitates the individual replacement of the corresponding power transmission line.

[0010] Furthermore, both ends of the upper and lower belts are fixed with baffles, which are respectively fixed to the corresponding terminals and the baffles are designed to block the terminals of the corresponding terminals. This design can prevent the terminals of the terminals from being interfered with by external factors.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The locking mechanism of this utility model can drive the turntable and locking cylinder to rotate through the handle, so that the locking cylinder is fixed inside the locking hole, thereby preventing the plug from detaching from the socket (medical centrifuges will generate a certain degree of vibration during operation). Secondly, when it is necessary to separate the plug from the socket, the locking cylinder can be separated from the socket by rotating the turntable and locking cylinder.

[0013] 2. The terminal block of this utility model allows the power transmission line to be placed between two conductive plates. Then, the two conductive plates are pressed against the power transmission line by screws. Through the cooperation of the conductive plates and the data line, the power transmission line is electrically connected to the conductive post. When the power transmission line is damaged, it can be replaced by rotating the screws.

[0014] 3. The sealing strip of this utility model can be assembled together with the upper and lower strip bodies through the cooperation of the locking block and the locking groove to seal the power transmission line. When the power transmission line is damaged and needs to be replaced, the upper and lower strip bodies can be separated to facilitate the replacement of one of the power transmission lines individually.
