Description

Technical Field

[0001] The utility model relates to the field of medical device connectors, in particular to a protective structure for preventing internal components of a connector from being damaged by pressure. Background Art

[0002] Medical monitoring equipment is a precision medical instrument used to present various indicators of the patient's body in a digital form. For example, an ECG monitor has the functions of collecting, storing, intelligently analyzing and warning ECG information. This type of precision monitoring equipment relies on various connectors to achieve data transmission, and the connectors must have the characteristics of anti-interference and strong connection stability.

[0003] The ECG monitoring equipment connectors currently on the market contain multiple defibrillators, which are not isolated from each other (or the isolation area is small and does not completely cover the defibrillators). During the internal mold injection molding process, the high-speed jet pressure of the liquid rubber during the injection molding process will affect these defibrillators and cause damage. After the final curing, they are affected by the solid colloid stress and are prone to cracking. In addition, due to the lack of a barrier structure, the creepage distance between two adjacent defibrillators is short, which makes it easy for creepage to be conductive.

[0004] In view of this, the present technical solution proposes a protective structure for preventing the internal components of the connector from being damaged by pressure. It does not affect the injection molding stability, but also has protective barrier properties for the internal components, thereby protecting the internal components from being damaged by the pressure of the injection molded parts and extending the service life. Utility Model Content

[0005] The technical solution of the utility model aims to solve at least one of the technical problems in the related art to a certain extent. To this end, the main purpose of the utility model is to provide a protective structure for preventing the internal components of the connector from being damaged by pressure, aiming to solve the problem that the connector structure of the monitoring equipment in the prior art lacks component protection and barrier structure, resulting in the connector being prone to failure, easy to damage and having a short service life.

[0006] To achieve the above-mentioned purpose, the utility model provides a protective structure for preventing the internal components of a connector from being damaged by pressure, comprising a connector body composed of an internal component assembly, an injection mold and an external cover shell.

[0007] The internal component assembly includes a protective plate body, and defibrillators arranged on one side of the protective plate body, the top of the defibrillator is connected to a terminal, and the bottom of the defibrillator is connected to a pin.

[0008] First partitions are arranged in sequence on one side of the protective plate body, and a first groove for placing the defibrillator is formed between adjacent first partitions. Second partitions are arranged on the other side of the protective plate body, and a second groove is formed between adjacent second partitions. The pin passes through one side of the protective plate body and is placed in the second groove.

[0009] The inner injection mold is coated on the outside of the internal component assembly, and the outer cover is coated on the outside of the inner injection mold.

[0010] As a further solution of the utility model, a gap of 0.3-0.5 mm is left between the defibrillator and the protective plate body.

[0011] As a further solution of the present invention, the protective plate body is consistent with the outer contour of the injection inner mold.

[0012] As a further solution of the utility model, support columns for enhancing the fixing strength with the injection inner mold are provided at the corners of the protective plate body.

[0013] As a further solution of the utility model, a socket is sleeved on the top of the terminal.

[0014] As a further solution of the utility model, a latch column which is easy to be fixed to the socket is provided on the top of the protective plate body.

[0015] As a further solution of the present invention, the protective plate body is an integrally injection-molded insulating plastic plate structure.

[0016] The beneficial effects of the utility model are as follows:

[0017] The protective structure for preventing the internal components of the connector from being damaged by pressure is proposed in the utility model. By setting a protective plate body with partitions on both sides, each defibrillator is located in a separate groove, and the pins on the other side are also located in a separate groove, which is used to increase the creepage distance between two adjacent defibrillator devices and pins, and when passing through the injection molding inner mold, the liquid high-temperature rubber flow is disturbed during the molding of the inner mold, buffering the high-speed jet pressure of the liquid rubber during injection molding, and protecting the defibrillator device from being damaged during the injection molding process. The overall protective structure is simple, does not affect the injection molding stability, is easy to assemble and produce, and also has the barrier to the internal components and certain anti-interference characteristics.

[0025] DETAILED DESCRIPTION

[0026] as follows:

[0027] Please refer to the attached Figure 1-4 ,

[0028] The main structure includes a connector body 1 composed of an internal component assembly 10, an injection mold 12 and an external cover 13. The internal component assembly 10 includes a protective plate body 100, and defibrillators 104 arranged on one side of the protective plate body 100. The top of the defibrillator 104 is connected to a terminal 103, and the bottom of the defibrillator 104 is connected to a pin 105. First partitions 101 are arranged in sequence on one side of the protective plate body 100, and a first groove 102 for placing the defibrillator 104 is formed between each adjacent first partition 101. A second partition 106 is provided on the other side of the protective plate body 100, and a second groove 107 is formed between each adjacent second partition 106. The pin 105 passes through one side of the protective plate body 100 and is placed in the second groove 107. The injection mold 12 is coated on the outside of the internal component assembly 10, and the external cover 13 is coated on the outside of the injection mold 12.

[0029] Here’s how it works:

[0030] The main body 100 of the protective plate of the defibrillator 104 is made of nylon and glass fiber plastic materials through injection molding process. A plurality of electrical isolation walls (first partition 101, first groove 102, second partition 106, second groove 107) are designed on both sides of the plastic plate, which have two main functions: first, the adjacent defibrillators 104 and the pins 105 of the defibrillators 104 are separated, which is used to increase the creepage distance between two adjacent defibrillators 104; second, when the inner mold (injection inner mold 12) is formed, the flow of the liquid high-temperature rubber material is disturbed, the high-speed jet pressure of the liquid rubber material during injection molding is buffered, and the defibrillator 104 is protected from being damaged during the injection molding process. In addition, since the protective plate main body 100 and each partition are not in hard contact with the defibrillator 104 and the pins 105, but leave gaps, the internal stress is small after injection molding, and it is not easy to burst and damage.

[0031] Reference Figure 2 A preferred embodiment of the present invention is as follows: a gap of 0.3-0.5 mm is left between the defibrillator 104 and the protective plate body 100 .

[0032] After the defibrillator 104 is installed on the protective plate body 100, a gap of 0.3-0.5mm is left between the defibrillator 104 and the protective plate body 100, so that liquid rubber can fill the gap during inner mold injection to fully wrap the defibrillator 104, so as to protect the defibrillator 104 from breaking under harsh use, transportation, etc.

[0033] Reference Figure 2 , 3 4. A preferred embodiment of the present invention: the outer contour of the protection plate body 100 is consistent with the outer contour of the injection mold 12. A support column 109 is provided at the corner of the protection plate body 100 for enhancing the fixing strength with the injection mold 12.

[0034] The protective plate body 100 is also designed with multiple (generally 4) support columns 109 located at the corners of the protective plate body 100. The support columns 109 are used to stand on the upper and lower model cavities of the mold after the inner mold is closed to keep the entire protective plate body 100 parallel to the injection inner mold 12 with the same contour, and will not be displaced under the high-pressure impact of the high-speed jet liquid rubber.

[0035] Reference Figure 2 A preferred embodiment of the present invention is as follows: a socket 11 is sleeved on the top of the terminal 103 .

[0036] The provided socket 11 is convenient for connection with external equipment.

[0037] Reference Figure 3 A preferred embodiment of the present invention is as follows: a latch post 108 is provided on the top of the protective plate body 100 for easy fixation with the socket 11 .

[0038] The provided latch post 108 is convenient for fixing with the socket 11 .

[0039] In a preferred embodiment of the present invention, the protection plate body 100 is an integrally injection-molded insulating plastic plate structure.

[0040] The protective plate body 100 can be made of nylon and glass fiber plastic material through injection molding process, which not only has high strength and high temperature resistance, but also has good insulation performance and is not easy to age and deform.

[0041] The above are only preferred embodiments of the technical solution of the utility model, and do not limit the patent scope of the technical solution of the utility model. All equivalent structural changes made by using the contents of the technical solution description and drawings of the utility model under the conception of the technical solution of the utility model, or direct / indirect application in other related technical fields are included in the patent protection scope of the technical solution of the utility model.
