Abstract
Description
Technical Field
[0001] This utility model relates to the field of connectors, and in particular to a male connector for medical devices. Background Technology
[0002] With the advancement of technology, medical devices are now widely used in the medical field for treatment. Connectors are inevitably required for power and signal transmission during the use of these devices. Medical connectors need to be able to connect and disconnect quickly, facilitating rapid assembly and disassembly of medical devices, especially in emergencies to save time during treatment. On the other hand, they must also ensure stable connection and transmission. If the connector becomes unstable or even detaches during use, it will cause malfunctions in the medical device, adversely affecting the treatment process.
[0003] To achieve quick connection and disconnection, most medical devices use mating connectors. However, existing male connectors for medical devices typically use a 0.4mm thick nickel-plated iron shell for the front housing and hollow pins for the PINs. The front housing and hollow pins need to be mated with the female connector. With repeated mating, the iron front housing is prone to deformation and rust, affecting connection stability and lifespan. Furthermore, the iron front housing is magnetic, which can interfere with signals from certain instruments, affecting signal transmission stability. The hollow pins, on the other hand, have low overall strength and are prone to bending or even breakage during insertion and removal. Therefore, existing male connectors for medical devices have poor connection stability, resulting in poor power and signal transmission stability, susceptibility to damage, and short lifespan. Consequently, existing male connectors for medical devices cannot meet the requirements of medical device use.
[0004] Therefore, it is necessary to provide a technical solution to address the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a male connector for medical devices that can solve the technical problems of poor connection stability, resulting in poor power and signal transmission stability, easy damage, and short service life of existing male connectors for medical devices.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] A male connector for medical devices includes a front housing and a rear housing connected to each other. The rear housing has a core in which a plurality of solid pins are evenly inserted. The wall thickness of the front housing is 3 to 6 times that of the rear housing, and the wall thickness of the front housing is 1.5 to 2.5 mm.
[0008] Furthermore, the front housing is made of zinc alloy.
[0009] Furthermore, the front housing is formed by die casting.
[0010] Furthermore, the front housing includes a first connecting plate and a plug-in frame located on the side of the first connecting plate away from the rear housing, the rear housing includes a second connecting plate and a receiving frame located on the side of the second connecting plate away from the front housing, the adhesive core is disposed in the receiving frame, and the mating end of the solid PIN extends into the plug-in frame.
[0011] Furthermore, both ends of the first connecting plate are provided with connecting holes, and both ends of the second connecting plate are respectively provided with riveting protrusions that can be inserted into the connecting holes.
[0012] Furthermore, the wall thickness of the riveting protrusion is 2 to 3 times the wall thickness of the rear housing.
[0013] Furthermore, the end of the plug-in frame away from the first connecting plate is provided with an inclined guide surface.
[0014] Furthermore, the cross-sections of the insertion frame, the receiving frame, and the adhesive core are all rounded trapezoidal in shape.
[0015] Furthermore, the receiving frame has an opening at one end away from the front housing, and the rubber core has a protrusion at one end away from the front housing, the protrusion being inserted into the opening.
[0016] The beneficial effects of this utility model are:
[0017] (1) By increasing the wall thickness of the front housing, the strength of the front housing is increased, and the front housing is less likely to deform during insertion and removal, ensuring that the male connector and the female connector can be smoothly inserted, and improving the connection stability and extending the service life of the male connector and the female connector.
[0018] (2) The PIN pins are solid PIN pins. Solid PIN pins have high overall strength and are not easily bent or damaged during insertion and removal, thereby further improving the connection stability of male and female connectors and extending their service life.
[0019] (3) By setting the material of the front housing to zinc alloy, on the one hand, the front housing can be prevented from rusting after a long period of use, and on the other hand, interference with the signals of certain instruments and equipment can be avoided, thus ensuring the stability of signal transmission.
[0020] (4) By providing an inclined guide surface at one end of the plug-in frame away from the first connecting plate, it helps to guide the plug-in end of the female connector into the interior of the plug-in frame during plug-in, thereby improving the plug-in efficiency between the male connector and the female connector.

[0029] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.
[0030] like Figures 1 to 6 As shown, the present invention provides a male connector for medical devices, comprising a front housing 1 and a rear housing 2 connected to each other. The rear housing 2 is provided with a rubber core 3, and a plurality of solid pins 4 are evenly inserted in the rubber core 3. The wall thickness of the front housing 1 is 3 to 6 times the wall thickness of the rear housing 2, and the wall thickness of the front housing 1 is 1.5 to 2.5 mm. Preferably, the wall thickness of the front housing 1 is 2 to 2.2 mm.
[0031] In practical use, since the front housing 1 needs to be plugged into and unplugged from the female connector, while the rear housing 2 does not, the shape and stability of the front housing 1 directly affect whether the male and female connectors can be smoothly plugged in and the stability of the plugging. In this embodiment, the wall thicknesses of the front housing 1 and the rear housing 2 are set differently according to their different usage methods, which can reduce costs while ensuring performance. Specifically, the wall thickness of the front housing 1 is set to 3 to 6 times that of the rear housing 2, thereby increasing the wall thickness and strength of the front housing 1. The front housing 1 is less prone to deformation during plugging and unplugging, ensuring smooth plugging between the male and female connectors, improving the connection stability of the male and female connectors, and extending their service life. In addition, solid PIN pins 4 are used. Compared with hollow PIN pins, solid PIN pins 4 have higher overall strength and are less prone to bending or damage during plugging and unplugging, thereby further improving the connection stability of the male and female connectors and extending their service life.
[0032] Furthermore, the front housing 1 is made of zinc alloy, specifically, the front housing 1 is formed by zinc alloy die casting. Zinc alloy is not easy to rust and is non-magnetic. In this embodiment, the material of the front housing 1 is set as zinc alloy, which can prevent the front housing 1 from rusting after long-term use, and can also avoid interference with the signals of certain instruments and equipment, thus ensuring the stability of signal transmission.
[0033] Furthermore, such as Figure 3 and 4 As shown, the front housing 1 includes a first connecting plate 11 and a plug-in frame 12 located on the side of the first connecting plate 11 away from the rear housing 2. The rear housing 2 includes a second connecting plate 21 and a receiving frame 22 located on the side of the second connecting plate 21 away from the front housing 1. The adhesive core 3 is disposed in the receiving frame 22, and the mating end of the solid PIN 4 extends into the plug-in frame 12. In this embodiment, by providing the first connecting plate 11 and the second connecting plate 21, the connection between the front housing 1 and the rear housing 2 is facilitated. The sides of the first connecting plate 11 and the second connecting plate 21 that are close to each other are both flat, so when the front housing 1 and the rear housing 2 are connected, the sides of the first connecting plate 11 and the second connecting plate 21 that are close to each other are in close contact.
[0034] Furthermore, such as Figure 3 , 4As shown in Figure 6, both ends of the first connecting plate 11 are provided with connecting holes 13, and both ends of the second connecting plate 21 are respectively provided with riveting protrusions 23 that can be inserted into the connecting holes 13. Preferably, the wall thickness of the riveting protrusions 23 is 2 to 3 times the wall thickness of the rear housing 2. When the front housing 1 and the rear housing 2 are connected, the riveting protrusions 23 are inserted into the connecting holes 13, which facilitates the positioning between the front housing 1 and the rear housing 2; in addition, during the connection process of the front housing 1 and the rear housing 2, the connection between the two is achieved by extruding and deforming the riveting protrusions 23; in this embodiment, by increasing the wall thickness of the riveting protrusions 23, the connection strength between the front housing 1 and the rear housing 2 is improved, avoiding the separation of the front housing 1 and the rear housing 2 due to insufficient connection strength during use.
[0035] Furthermore, such as Figure 3 As shown, the end of the plug-in frame 12 away from the first connecting plate 11 is provided with an inclined guide surface 14. In this embodiment, by providing the inclined guide surface 14, it is helpful to guide the plug-in end of the female connector into the interior of the plug-in frame 12 during plugging, thereby improving the plugging efficiency between the male connector and the female connector.
[0036] Furthermore, such as Figure 2 As shown, the cross-sections of the insertion frame 12, the receiving frame 22, and the adhesive core 3 are all rounded trapezoidal. In this embodiment, by setting the cross-sections of the insertion frame 12, the receiving frame 22, and the adhesive core 3 to rounded trapezoidal shapes, a foolproof effect can be achieved during the insertion process.
[0037] Furthermore, such as Figure 5 As shown, the receiving frame 22 has an opening 24 at one end away from the front housing 1, and the glue core 3 has a protrusion 31 at one end away from the front housing 1, with the protrusion 31 inserted into the opening 24. In this embodiment, by providing the opening 24 and the protrusion 31, the position of the glue core 3 within the receiving frame 22 can be positioned.
[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
