[0012] In order to enable those skilled in the art to better understand the technical solution of the utility model, the preferred implementation scheme of the utility model is described below in conjunction with specific embodiments, but it should be understood that these descriptions are only for further illustrating the features and advantages of the utility model, rather than limiting the patent requirements of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0013] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0014] Example 1

[0015] See also Figure 1 and Figure 2 As shown, a medical device wiring harness involved in this embodiment includes a conversion head 1 with a rotary structure, one end of the conversion head 1 has a busbar 2, and the other end has a plurality of sub-wires 3 that are electrically connected to the busbar and distributed in a ring array around an axis, each of the sub-wires 3 is matched with a storage cavity 4 provided on the conversion head 1, a part of the sub-wire 3 is provided in the storage cavity 4, and the storage cavity 4 is provided with a wire hole 5 for leading out the sub-wire 3 and realizing axial positioning.

[0016] Furthermore, a plurality of annular positioning grooves 6 equidistantly arranged along the axial direction are provided on the outer wall of the sub-line 3 , and an elastic locking tongue 7 provided on the hole wall of the line hole 5 is embedded in one of the annular positioning grooves 6 .

[0017] In this embodiment, first, the sub-wire 3 is in the longest effective length state, at which point the storage chamber 4 contains the least sub-wire 3. If the sub-wire 3 is found to be too long during the actual connection process, the exposed part can be held and pressure can be applied toward the storage chamber 4 to shrink the sub-wire 3 into the storage chamber 4 along the wire hole 5, shortening its effective length.

[0018] The annular positioning groove 6 cooperates with the elastic locking tongue 7 to adjust the limit position.

[0019] Example 2

[0020] See also Figure 1 and Figure 2As shown, the medical device wiring harness involved in this embodiment is further configured as follows on the basis of Embodiment 1: the storage cavity 4 is cylindrical; the storage cavity 4 is distributed in a circular array around the axis of the conversion head 1; the axis of the storage cavity 4 is parallel to the axis of the conversion head 1.

[0021] Furthermore, the wire hole 5 is arranged at one end of the storage cavity 4 away from the busbar 2 , and the connection between the sub-wire 3 and the conversion head 1 is arranged at the other end of the storage cavity 4 .

[0022] Furthermore, the wire hole 5 and the connection between the sub-wire 3 and the conversion head 1 are arranged in a non-coaxial line.

[0023] In this embodiment, through the setting of the above-mentioned structure, the wire hole 5 and the connection between the sub-wire 3 and the conversion head 1 are arranged in a non-coaxial line, so that when the sub-wire 3 is subjected to axial force, the sub-wire 3 can be quickly retracted into the storage cavity 4 due to the non-coaxial connection between the wire hole 5 and the connection between the sub-wire 3 and the conversion head 1, which facilitates the adjustment operation.

[0024] The medical device wire harness of the utility model is provided with a storage cavity for adjusting the actual use length of each sub-wire, so that the excessively long sub-wire portion can be retracted into the storage cavity, thereby preventing the sub-wire from being entangled with other sub-wires due to exposure of the sub-wire. The utility model is anti-entanglement, easy to store, has complete overall functions and is highly practical.
