Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a medical device harness connector that is convenient for quick plugging and unplugging. Background Art

[0002] In the medical device sector, quick-plug harness connectors are widely used in monitors, surgical instruments, in vitro diagnostic equipment, and other medical devices because they significantly simplify operational processes and improve device connection efficiency. To achieve the convenience of quick plugging and unplugging, current mainstream harness connectors are typically designed to be open and exposed when not connected, with the connection port directly exposed to the external environment.

[0003] While this open structure facilitates operation, it suffers from significant technical drawbacks. In medical environments, dust particles floating in the outside air can easily accumulate on the surface of the connector's metal contacts, forming an insulating layer that affects current conduction. Water vapor adsorption and condensation can cause oxidation of the metal contacts, significantly increasing contact resistance and reducing connection stability. Furthermore, corrosive gases (such as those produced during disinfection) that may be present in medical settings can react chemically with the metal contacts, accelerating corrosion. These issues not only degrade connector transmission performance and cause electrical faults such as signal interruption and data loss, but can also pose safety risks during medical device operation, potentially endangering the patient's life.

DETAILED DESCRIPTION

[0030] The present invention is further described with reference to the following examples.

[0031] Depend on Figures 1 to 7 It can be seen that the medical device harness connector for quick plugging and unplugging described in this embodiment includes a probe body 11 and a harness body 12; the probe body 11 is provided with a first connector 2; the harness body 12 is provided with a second connector 3 that cooperates with the first connector 2;

[0032] The first connector 2 is provided with a plug-in channel 21; a first terminal 22 is provided in the plug-in channel 21; a shielding plate 4 is provided in the plug-in channel 21 along the longitudinal direction thereof in a sealed and sliding manner; the shielding plate 4 is provided with a first opening 41 at a position corresponding to the first terminal 22; a first valve plate is movably provided in the first opening 41;

[0034] The second connector 3 is provided with a driving component for driving the second valve plate to move; a linkage component is provided between the second valve plate and the first valve plate.

[0035] Specifically, in the medical device wiring harness connector that is easy to plug and unplug for quick use described in this embodiment, before the first connector 2 and the second connector 3 are plugged in, the first valve plate covers the first opening 41, and the second valve plate covers the first opening 41, thereby sealing the first terminal 22 in the plug-in channel 21, and sealing the second terminal 32 in the protective shell 5, effectively preventing the external environment from polluting and corroding the first terminal 22 and the second terminal 32, and ensuring that the connector maintains good electrical performance even when it is not connected.

[0036] When the first connector 2 and the second connector 3 need to be plugged in, the protective shell 5 and the second connector 3 are inserted into the plug-in channel 21, and then the driving component drives the second valve plate to move, thereby opening the second opening 51. At the same time, the second valve plate drives the first valve plate to move through the linkage component, thereby opening the first opening 41, so that the first terminal 22 is in contact with the second terminal 32, completing the electrical conduction between the probe body 11 and the wiring harness body 12.

[0037] The present embodiment describes a medical device wiring harness connector that is easy to quickly plug and unplug, wherein the first valve plate includes a first left valve plate 43 and a first right valve plate 44 that abut against each other; the baffle plate 4 is provided with a first sealed cavity 42 that is connected to the first opening 41; the first left valve plate 43 and the first right valve plate 44 are respectively slidably arranged on both sides of the first sealed cavity 42; through the above arrangement, the first opening 41 can be effectively shielded or opened.

[0038] The second valve plate includes a second left valve plate 53 and a second right valve plate 54 that abut against each other; the protective shell 5 is provided with a second sealed cavity 52 that communicates with the second opening 51; the second left valve plate 53 and the second right valve plate 54 are respectively slidably arranged on both sides of the second sealed cavity 52; through the above arrangement, the second opening 51 can be effectively covered or opened.

[0039] The present embodiment describes a medical device harness connector that facilitates quick plugging and unplugging. The drive assembly includes a drive ring 6 that is rotatably mounted on the inner wall of the protective shell 5. The drive ring 6 is slidably mounted on the outer periphery of the plug-in boss 31. A drive pin 61 is provided at one end of the drive ring 6. An arcuate guide groove 56 is provided through the second sealing cavity 52. Both the second left valve plate 53 and the second right valve plate 54 are provided with linear guide grooves 57. The drive pin 61 is provided through the arcuate guide groove 56 and the linear guide groove 57. The present embodiment describes a medical device harness connector that facilitates quick plugging and unplugging. The drive ring 6 includes a rotation pin 62 at the other end. A rotation groove is provided on the outer wall of the plug-in boss 31. The rotation pin 62 is movably mounted in the rotation groove.

[0040] Specifically, through the above-mentioned arrangement, in this embodiment, when relative sliding occurs between the protective shell 5 and the second connector 3, and when the rotating pin 62 moves in the spiral rotating groove 35, the drive ring 6 rotates relative to the protective shell 5, and under the limiting action of the arc guide groove 56 and the linear guide groove 57, the two driving pins 61 drive the second left valve plate 53 and the second right valve plate 54 to approach or move away from each other; that is, when relative sliding occurs between the protective shell 5 and the second connector 3, the second left valve plate 53 and the second right valve plate 54 can be driven to approach or move away from each other, thereby enabling the second opening 51 to be covered or opened.

[0041] The medical device wiring harness connector of this embodiment, which facilitates quick plugging and unplugging, comprises a linkage assembly comprising a slot 72 provided on each of the first left valve disc 43 and the first right valve disc 44, and a block 71 provided on each of the second left valve disc 53 and the second right valve disc 54. The block 71 is configured to engage with the slot 72. This arrangement allows the first left valve disc 43 and the first right valve disc 44 to move away from each other through the engagement of the block 71 and the slot 72.

[0042] In the medical device wiring harness connector for quick plugging and unplugging described in this embodiment, a first sealing spring 45 is provided between the first left valve disc 43 and the first sealed cavity 42, and between the first right valve disc 44 and the first sealed cavity 42. The provision of the first sealing spring 45 facilitates the return of the first left valve disc 43 and the first right valve disc 44 to abut each other.

[0043] The present embodiment describes a medical device harness connector that is easy to quickly plug and unplug, and a first return spring 23 is provided between the shielding plate 4 and the plug-in channel 21; the above arrangement facilitates the reset of the shielding plate 4; a second return spring 36 is provided between the protective shell 5 and the second connector 3; the above arrangement facilitates the reset of the protective shell 5.

[0044] This embodiment describes a medical device wiring harness connector that facilitates quick plugging and unplugging. A buffer spring 81 is provided between the first terminal 22 and the insertion channel 21; this arrangement protects the first terminal 22 and the second terminal 32. The first connector 2 is provided with an airbag 82 that communicates with the insertion channel 21. This arrangement allows air to flow between the insertion channel 21 and the airbag 82 as the shielding plate 4 moves, effectively maintaining a stable internal pressure and preventing excessive pressure from affecting the device.

[0045] The present embodiment describes a medical device harness connector that facilitates quick plugging and unplugging. The inner wall of the insertion channel 21 is provided with a first limiting plane 91; the outer wall of the protective shell 5 is provided with a second limiting plane 92 that cooperates with the first limiting plane 91; the first limiting plane 91 is provided with a locking pin 93 that is movable and retractable; a locking spring 94 is provided between the locking pin 93 and the first connector 2; the outer wall of the first connector 2 is provided with a handle 13; the handle 13 is connected to the locking pin 93; the outer wall of the protective shell 5 is provided with an abutting inclined surface 95 that cooperates with the locking pin 93; the protective shell 5 is provided with a through-hole 96; the second connector 3 is provided with a locking hole 97; the locking pin 93 is locked with the locking hole 97 through the through-hole 96. The above arrangement facilitates locking of the first connector 2 and the second connector 3.

[0046] Specifically, in the medical device wiring harness connector that is easy to plug and unplug for quick use described in this embodiment, before the first connector 2 and the second connector 3 are plugged in, the first valve plate covers the first opening 41, and the second valve plate covers the first opening 41, thereby sealing the first terminal 22 in the plug-in channel 21, and sealing the second terminal 32 in the protective shell 5, effectively preventing the external environment from polluting and corroding the first terminal 22 and the second terminal 32, and ensuring that the connector maintains good electrical performance even when it is not connected.

[0047] When the first connector 2 and the second connector 3 need to be plugged together, the protective shell 5 and the second connector 3 are inserted into the plugging channel 21. Under the action of the abutting inclined surface 95, the locking pin 93 is pushed to retract into the first connector 2, and the second connector 3 is pushed to move into the plugging channel 21, so that the protective shell 5 abuts against the shielding plate 4, and the clamping block 71 abuts against the clamping groove 72.

[0048] By setting the rigidity of the first return spring 23 to be greater than the rigidity of the second return spring 36, the second connector 3 is continuously pushed to move, so that relative sliding occurs between the protective shell 5 and the second connector 3, so that the rotating pin 62 moves in the spiral rotating groove 35, so that the driving ring 6 rotates relative to the protective shell 5. Under the limiting action of the arc guide groove 56 and the linear guide groove 57, the two driving pins 61 drive the second left valve disc 53 and the second right valve disc 54 to move away from each other, thereby opening the second opening 51. At the same time, through the cooperation between the clamping block 71 and the clamping groove 72, the first left valve disc 43 and the first right valve disc 44 are driven to move away from each other, thereby opening the first opening 41; until the rotating pin 6 When the protective shell 5 moves to the end of the second linear rotation slot 34, relative sliding between the protective shell 5 and the second connector 3 cannot occur. Therefore, the second connector 3 is continuously pushed to move into the insertion channel 21, driving the protective shell 5 and the shielding plate 4 to continue to move into the insertion channel 21 until the through-hole 96 and the locking hole 97 move to the position of the locking pin 93. Under the action of the locking spring 94, the locking pin 93 is reset and locked through the through-hole 96 and the locking hole 97. At this time, the first terminal 22 passes through the first opening 41, and the second terminal 32 passes through the second opening 51. The first terminal 22 contacts the second terminal 32, completing electrical conduction between the probe body 11 and the wiring harness body 12.

[0049] When it is necessary to separate the first connector 2 from the second connector 3, it is only necessary to drive the locking pin 93 through the handle 13 so that the locking pin 93 is withdrawn from the through hole 96 and the locking hole 97. Under the action of the first return spring 23, the second return spring 36 and the first sealing spring 45, the first connector 2 and the second connector 3 are reset; and in the process of the shielding plate 4 being reset, the shielding plate 4 sweeps the dust in the plug-in channel 21 to the dust outlet 90,

[0050] In this embodiment, a medical device harness connector for quick plugging and unplugging is described. The inner wall of the insertion channel 21 is provided with a retaining groove 98. The shielding plate 4 is provided with a retaining block 99, which slides within the retaining groove 98. A dust outlet 90 extends through the end of the retaining groove 98 away from the first terminal 22. This arrangement serves to guide and limit the sliding movement of the shielding plate 4 and to sweep dust from the insertion channel 21 into the dust outlet 90.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
