Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a cable connection structure of a transducer. Background Art

[0002] Medical ultrasound imaging has been widely used due to its advantages such as good real-time performance and no ionizing radiation. During the installation process, most of the transducer cables are fixed by gluing, screws and riveting, which are easy to fall off. Therefore, cable sheaths are designed on the market to enhance the installation stability of the cable. Before the transducer is integrated into the cable bundle in the cable sheath, the cores with different functions are separated from each other. The market often adopts the method of wrapping the core with copper sheets to constrain it and then insert it into the cable for integration. Because the outer contour after wrapping is poorly matched with the internal space of the cable sheath, it is easy to shake in the cable sheath, and the structure is unstable.

[0003] For example, a Chinese utility model patent discloses a transducer and its cable sheath [application number: CN201721072904.0]. The utility model provides a transducer and its cable sheath, the cable sheath comprising: a metal body, a cable line, a sleeve and an outer shell. The metal body has an axially through-going connecting hole; the cable line is arranged through the connecting hole of the metal body; the sleeve is integrally formed on the periphery of the metal body, and the sleeve extends from the periphery of the metal body in a direction away from the metal body and wraps around the periphery of the cable line, and the sleeve and the metal body together constitute the cable sheath body; the outer shell is sleeved on the periphery of the cable sheath body. The sleeve of the cable sheath of the utility model is integrally formed on the periphery of the metal body and wraps around the periphery of the cable line, and the sleeve and the metal body together constitute the cable sheath body, and the sleeve, the metal body and the cable line are firmly connected to each other, which effectively solves the problem of the cable sheath body falling off and cracking from the cable line, and improves the reliability of the transducer tail.

[0004] Although the utility model solves the problem of the cable sheath body falling off and cracking from the cable to a certain extent by forming the sheath integrally on the periphery of the metal body and wrapping it around the periphery of the cable, it still does not solve the problem of the connection stability of the dispersed wire cores relative to the cable sheath body before the cable is integrated in the cable sheath. Summary of the invention

[0005] The purpose of the utility model is to provide a cable connection structure of a transducer in view of the above problems.

[0006] The utility model provides a cable connection structure of a transducer, comprising a sheath, a cable harness and a metal tube body, wherein the cable harness passes through the sheath and into the interior of the metal tube body, and is characterized in that the cable harness comprises a protective layer and a wire core sheathed in the protective layer, and the metal tube body is also provided with a locking structure for fastening the wire core, and one end of the locking structure is pressed on the wire core to stabilize the connection between the wire core and the metal tube body.

[0008] Preferably, the first locking assembly includes a first contact portion and a first locking structure, and the first locking structure is used to push the first contact portion and the wire core against each other.

[0009] Specifically, the first locking assembly includes a metal bolt and a bolt hole penetrating the metal tube body, and the first contact portion is connected to one end of the metal bolt.

[0010] Preferably, the first contact portion is an arc-shaped wire protection sheet structure that can fit with the inner wall of the metal tube.

[0011] To achieve the grounding function, the first contact part is a conductive material, and the grounding wire in the wire core is electrically connected to the first contact part. As a common means, the insulation layer of the grounding wire can be stripped off and then each wire core can be wrapped and fixed with copper foil. The metal wire in the grounding wire directly contacts the copper foil, and the first contact part fits the outside of the copper foil.

[0012] As another solution, the first locking structure includes a clamp, the clamp buckle of the clamp is arranged outside the metal tube body, one end of the first contact part is connected to the metal tube body, one end of the clamp band of the clamp is connected to the first contact part, and the other end passes through the metal tube body from the inside to the outside, and the clamp band is tightened to make the first contact part close to the cable harness. That is, the metal band is contracted to tighten the wire core and the clamp buckle is used to lock the metal band outside the metal tube to maintain the state.
