Description

Technical Field

[0001] The utility model relates to the field of medical device connectors, and particularly to a connector with an anti-interference channel transmission structure. Background Art

[0002] Medical monitoring devices are precision medical instruments used to digitally present various physical index data of patients. For example, an electrocardiogram monitor has functions such as acquisition, storage, and intelligent analysis and early warning of electrocardiogram information. Such precision monitoring devices rely on various connectors to achieve data transmission, and the connectors must have the characteristics of anti-interference and strong connection stability.

[0003] In the prior art, data connectors for medical monitoring are prone to being affected by external signals or interference caused by water vapor conduction. The main reasons for the easy crosstalk, short "creepage" distance, and few isolation measures are the main reasons for the easy interference of signals. In addition, even if there is a separately provided anti-interference channel in the current connector, the setting method is to stagger it with the electrical signal channel, that is, an anti-interference channel needs to undertake the anti-interference work of the electrical signal channels on both sides. In this way, the performance of the anti-interference channel is weakened, and after long-term use, the anti-interference channel may act as a "creepage" medium, further increasing the risk of crosstalk.

[0004] In view of this, the technical solution of this application proposes a connector with an anti-interference channel transmission structure, which not only improves the isolation measures, increases the "creepage" distance, but also adopts a single-type single-row arrangement method, and through the separate isolation space set for each contact terminal, the interference received by the signal is minimized, further improving the accuracy of monitoring data. Summary of the Utility Model

[0005] The technical solution of the utility model aims to solve at least one of the technical problems in the related art to some extent. For this reason, the main purpose of the utility model is to provide a connector with an anti-interference channel transmission structure, aiming to solve the problem that the data connector of the medical monitoring device in the prior art lacks an effective signal anti-interference structure, resulting in low data acquisition accuracy.

[0006] To achieve the above purpose, the utility model provides a connector with an anti-interference channel transmission structure, including a connector body composed of each contact terminal and a socket assembly.

[0007] Each of the contact terminals is arranged in a double-row structure corresponding in quantity, and the double-row structure respectively forms a biological electric channel group and a noise reduction channel group located on one side of the biological electric channel group.

[0008] The socket component includes an insulating wall formed by enclosing the bottom and the periphery of each individual contact terminal. An insertion panel is formed on the open side of each insulating wall, and the top of the contact terminal is located below the plane of the insertion panel.

[0009] As a further solution of the present invention, the distance between the top of the contact terminal and the top opening of the insulating wall is at least 1 / 3 of the depth of the insulating wall.

[0010] As a further solution of the present invention, the socket component is an integrally formed insulating plastic housing structure.

[0011] As a further solution of the present invention, the connector body further includes an inner mold shell that covers and fixes the contact terminal and the socket component, and an outer cover shell is provided outside the inner mold shell.

[0012] As a further solution of the present invention, the bottom of the contact terminal passes through the inner mold shell and the outer cover shell and is connected to a wire.

[0013] As a further solution of the present invention, the contact terminal is disposed at the middle position of the insulating wall space.

[0014] As a further solution of the present invention, the number of the biological signal channels and the noise reduction channels provided on the connector body is two groups, and they are arranged side by side.

[0015] The beneficial effects of the present invention are as follows:

[0016] The connector with an anti-interference channel transmission structure proposed by the present invention realizes the barrier after insertion through the insulating wall that "isolates" each contact terminal separately, which can not only prevent external water vapor and dust from entering to form a path, but also increase the "creepage" distance between the contact terminals. The double-row structure separates the biological signal channels from the noise reduction channels, avoiding the interference caused by the staggered structure. The overall structure is simple, and there is no need to set up a complex shielding structure, which can effectively reduce external interference and internal mutual interference. The entire socket component adopts an integrally formed insulating plastic shell structure, which is easy to assemble and mass-produce. Description of the Drawings

[0023] Label Name Label Name 1 Connector body 14 Socket assembly 10 External housing 140 Insulating wall 11 Inner mold shell 141 Plug-in panel 12 Wire 142 Bio-telecommunication channel group 13 Contact terminal 143 Noise reduction channel group Specific embodiments

[0024] Are as follows:

[0025] Please refer to the attached Figures 1-4 ,

[0026] The main structure includes a connector body 1 composed of contact terminals 13 and a plug-in socket assembly 14. The contact terminals 13 are arranged in a double-row structure corresponding in number. The double-row structure forms a biological telecommunication channel group 142 and a noise reduction channel group 143 located on one side of the biological telecommunication channel group 142 respectively. The plug-in socket assembly 14 includes an insulating wall 140 formed by enclosing the bottom and the periphery of each individual contact terminal 13. An opening side of each insulating wall 140 forms a plug-in panel 141, and the top of the contact terminal 13 is located below the plane of the plug-in panel 141.

[0027] The working principle is as follows:

[0028] Through the insulating wall 140 formed by separately enclosing each contact terminal 13, the contact terminals 13 of each channel (noise reduction channel group 143, biological telecommunication channel group 142) are completely isolated, and the height of the contact terminal 13 is lower than the top of the insulating wall 140, which is not only easy for plugging and installation, but also extends the "creepage" distance and weakens the effect of signal crosstalk between each channel. After being plugged and connected to other devices, the insulating wall 140 will form a closed space, further blocking external interference. And the double-row structure set separates the biological telecommunication channel group 142 from the noise reduction channel group 143, avoiding the interference situation generated by the staggered structure.

[0029] Referring to the attached Figure 4 , in a preferred embodiment of the present utility model: the distance between the top of the contact terminal and the top opening of the insulating wall 140 is at least 1 / 3 of the depth of the insulating wall 140.

[0030] If the top of the contact terminal is too close to the top opening of the insulating wall 140, there will still be a certain "creepage" problem. If the distance between the top of the contact terminal and the top opening of the insulating wall 140 is set to be greater than or equal to 1 / 3 of the depth of the insulating wall 140, the "creepage" problem can be eliminated to the greatest extent, and the adaptability to other device interfaces is not affected.

[0031] Refer to the attached drawings of the specification Figure 3 In a preferred embodiment of the present utility model: the socket assembly 14 is an integrally formed insulating plastic housing structure.

[0032] The entire socket assembly 14 adopts an integrally formed insulating plastic housing structure, which is easy to assemble and mass-produce.

[0033] Refer to the attached drawings of the specification Figure 3 In a preferred embodiment of the present utility model: the connector body 1 further includes an inner mold shell 11 that covers and fixes the contact terminal and the socket assembly 14, and an outer cover shell 10 is provided outside the inner mold shell 11.

[0034] The provided inner mold shell 11 is used to fix the internal structure and also has a certain shielding effect on external signals.

[0035] Refer to the attached drawings of the specification Figure 3 In a preferred embodiment of the present utility model: the bottom of the contact terminal 13 passes through the inner mold shell 11 and the outer cover shell 10 and is connected to the wire 12.

[0036] Refer to the attached drawings of the specification Figure 2 In a preferred embodiment of the present utility model: the contact terminal 13 is arranged at the middle position of the space of the insulating wall 140.

[0037] Refer to the attached drawings of the specification Figure 2 In a preferred embodiment of the present utility model: the number of the biological signal channel groups 142 and the noise reduction channel groups 143 on the connector body 1 is two, and they are arranged side by side.

[0038] Each transmission channel can be set to be composed of a standard rectangular channel and a special-shaped channel. In this solution, 10 monitoring points can be set (20 transmission channels, 10 standards and 10 special-shaped ones) to meet the plug-in requirements of various specifications.

[0039] The above are only the preferred embodiments of the technical solution of the present utility model, and do not limit the patent scope of the technical solution of the present utility model. Any equivalent structural transformation made under the inventive concept of the technical solution of the present utility model by using the content of the specification and drawings of the technical solution of the present utility model, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the technical solution of the present utility model.
