DETAILED DESCRIPTION

[0039] An embodiment of the present application provides a connector 1 for a humidifier.

[0040] It can be understood that a humidifier can be used as a part of a medical ventilation device. The humidifier has a humidification function and can humidify the respiratory gas to deliver gas with suitable temperature and humidity to the patient.

[0041] An embodiment of the present application provides a humidifier, comprising the connector 1 of any embodiment of the present application.

[0042] It is understandable that medical ventilation equipment can be medical equipment such as ventilators and oxygen therapy devices that maintain breathing and ensure ventilation for patients with respiratory failure. Medical ventilation equipment includes humidifiers, which deliver gases with appropriate temperature and humidity to patients to replace the body's autonomous ventilation function. Medical ventilation equipment can be used for respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support therapy, and emergency resuscitation.

[0043] The humidifier has an air inlet interface and an air outlet interface, wherein the air inlet interface is used to introduce breathing gas, and the air outlet interface is used to connect the breathing tube. The air outlet interface is provided with a temperature detection terminal, which is used to detect the temperature of the breathing gas flowing through the air outlet interface.

[0044] Specifically, the medical ventilation device may also include a host, the host is provided with a gas outlet, a humidifier is installed on the host, an air inlet interface is connected to the gas outlet, the breathing gas enters the air inlet interface through the gas outlet, the gas output from the gas outlet is dry gas or gas with low relative humidity, and the humidifier humidifies the breathing gas to increase the humidity of the gas. In this way, the breathing gas output from the air outlet interface is a gas with high relative humidity, which is delivered to the patient through the breathing circuit to increase the patient's breathing comfort. The temperature detection terminal detects the breathing gas output from the air outlet interface so as to provide the patient with gas with suitable temperature and humidity.

[0045] The electrical terminal 102 of the connector 1 is pluggable with the temperature detection terminal.

[0046] Specifically, one end of the connector 1 away from the temperature detection terminal can be connected to the terminal device, so that the temperature detection terminal establishes an electrical connection with the terminal device. In this way, the temperature signal detected by the temperature detection terminal can be transmitted to the terminal device through the connector 1, so that the user can know the temperature change waveform of the breathing gas output from the air outlet interface, thereby controlling the temperature and humidity of the breathing gas output from the air outlet interface.

[0047] The electrical terminal 102 of the connector 1 is pluggable with the temperature detection terminal, that is, when it is necessary to obtain the temperature signal, the connector 1 can establish a connection with the temperature detection terminal by plugging, and when it is not necessary to obtain the temperature signal, the connection between the connector 1 and the temperature detection terminal can be cancelled by pulling. In this way, the connection method between the connector 1 and the temperature detection terminal is simple and convenient for users to operate.

[0048] For example, see Figures 1 to 7The connector 1 includes an electrical terminal structure 10 , a cable 11 , an inner mold structure 13 , a mesh tail 14 and a housing assembly 15 .

[0049] The electrical terminal structure 10 includes a fixing base 101 and an electrical terminal 102 fixed on the fixing base 101 .

[0050] The electrical terminal 102 is used to establish an electrical connection. For example, one end of the electrical terminal 102 can be connected to a temperature detection terminal provided on the humidifier, and the other end can be connected to a terminal device, so as to obtain the temperature change waveform of the humidified gas, thereby providing gas with a suitable temperature for the patient.

[0051] The fixing seat 101 can be used as a bearing component. The fixing seat 101 carries the electrical terminal 102 , so as to increase the connection stability between the electrical terminal 102 and other components and increase the structural reliability of the connector 1 .

[0052] It is understandable that the number of electrical terminals 102 is not limited, and may be one or more, and is not limited here.

[0053] One end of the cable 11 is electrically connected to the electrical terminal 102 through the wire 12. That is, the wire 12 connects the electrical terminal 102 and the cable 11, the wire 12 transmits electrical signals, and the cable 11 can be connected to a terminal device. Specifically, one end of the wire 12 is connected to the electrical terminal 102, and the other end is connected to the cable 11. It should be noted that the cable 11 has one or more core wires inside, and the core wires are connected to the electrical terminal 102 through the wire 12.

[0054] The connection between the electrical terminal 102 and the wire 12 may be by welding or other connection methods, which are not limited here.

[0055] It should be noted that a single electrical terminal 102 may be an integrated structure, for example, the electrical terminal 102 passes through opposite ends of the fixing seat 101. A single electrical terminal 102 may also be formed by electrically connecting multiple components, for example, the electrical terminal 102 includes a pin and an adapter, the pin and the adapter are connected, the pin is used for electrical plugging and unplugging, and the adapter is used to connect to the wire 12.

[0056] It is understandable that in the related art, when the connector shakes, moves, or is subjected to external force, the connection between the electrical terminal and the wire is prone to cracking, causing problems such as internal circuit breaking, which affects the service life of the connector.

[0057] Therefore, the connector 1 of this embodiment is provided with an inner mold structure 13. The inner mold structure 13 at least wraps the connection part between the wire 12 and the electrical terminal 102. That is, the connection part between the wire 12 and the electrical terminal 102 is located in the space defined by the inner mold structure 13.

[0058] For example, in some embodiments, the electrical terminal 102 and the wire 12 are welded, the connection between the wire 12 and the electrical terminal 102 is a welding point, and the inner mold structure 13 wraps the welding point. In this way, the inner mold structure 13 can protect the connection between the wire 12 and the electrical terminal 102. When the connector 1 shakes, moves, or is subjected to external force, the inner mold structure 13 and the fixing seat 101 bear the force, reducing the probability of the wire 12 and the electrical terminal 102 being directly pulled, thereby reducing the probability of cracking at the connection between the electrical terminal 102 and the wire 12, and increasing the service life of the connector 1.

[0059] The tail 14 is wrapped around the outer periphery of one end of the cable 11 close to the electrical terminal structure 10, and the inner mold structure 13 connects the fixing seat 101 and the tail 14. A part of the tail 14 is accommodated in the housing assembly 15, and another part of the tail 14 extends out of the housing assembly 15.

[0060] Specifically, the shell assembly 15 can serve as an appearance component of the connector 1 , and the shell assembly 15 can provide a storage space for a portion of the net tail 14 , while another portion of the net tail 14 extends out of the shell assembly 15 to withstand the pulling force. In addition, the net tail 14 protects the cable 12 .

[0061] It is understandable that the electrical terminal structure 10 can be fully accommodated in the shell assembly 15, or only part of the electrical terminal structure 10 can be accommodated in the shell assembly 15. For example, the end of the electrical terminal 102 away from the cable 12 can extend out of the shell assembly 15 to facilitate electrical connection with other components. This is not limited here.

[0062] Exemplarily, the inner mold structure 13 is entirely contained within the housing assembly 15 .

[0063] In the related art, a connector is provided with a mesh tail, and the mesh tail wraps the outer circumference of the tail of the connector, so that the overall volume of the connector is large and the size is relatively large.

[0064] In the connector 1 provided in the embodiment of the present application, the inner mold structure 13 at least wraps the connection portion between the wire 12 and the electrical terminal 102, thereby reducing the probability of the connection portion between the wire 12 and the electrical terminal 102 being cracked and causing the internal circuit to be broken, thereby increasing the service life of the connector 1. When the connector 1 needs to be pulled to disconnect the connector 1 from other components, the overall structure formed by the mesh tail 14, the inner mold structure 13 and the fixing seat 101 withstands the pulling force, thereby reducing the probability of the cable 11 being bent and damaged due to the pulling force. The wire 12 and the connection portion between the wire 12 and the electrical terminal 102 are hardly subjected to the pulling force. In addition, part of the structure of the mesh tail 14 is arranged in the shell assembly 15, and the mesh tail 14 does not need to wrap the outer peripheral surface of the shell assembly 15, thereby effectively protecting the cable 11 while also making the overall size of the connector 1 smaller, so as to facilitate the miniaturization design of the connector 1.

[0065] The inner mold structure 13 may be formed in any manner, for example, by injection molding or by curing with glue.

[0066] The connection method between the mesh tail 14 and the inner mold structure 13 is not limited.

[0067] For example, in some embodiments, the net tail 14 is injection molded onto the inner mold structure 13 and the cable 11 .

[0068] That is to say, the net tail 14 is connected to the inner mold structure 13 and the cable 11 by injection molding. Specifically, after the inner mold structure 13 is connected to the electrical terminal structure 10 and the cable 11, part of the structure is placed in the mold, and the net tail 14 is molded on the inner mold structure 13 and the cable 11 by injection molding. In this embodiment, the net tail 14 is molded by injection molding, which is convenient to mold, does not require additional auxiliary connecting structure, reduces the connection process, and can be connected with the inner mold structure 13 and the cable 11. Stable.

[0069] In some other embodiments, the net tail 14 and the inner mold structure 13 are separate structures and are connected to each other.

[0070] It can be understood that the split structure of the net tail 14 and the inner mold structure 13 means that the net tail 14 and the inner mold structure 13 are separately formed structures, and the net tail 14 and the inner mold structure 13 are independent of each other.

[0071] In this embodiment, the net tail 14 and the cable 11 may be connected together first, for example, the net tail 14 and the cable 11 may be injection molded together, and then the net tail 14 may be connected to the inner mold structure 13 .

[0072] The connection method of the mesh tail 14 and the inner mold structure 13 is not limited. For example, the mesh tail 14 and the inner mold structure 13 can be connected by gluing, welding, etc.

[0073] In some embodiments, in a plane projection perpendicular to the extension direction of the electrical terminal 102 , the projection range of the mesh tail 14 does not exceed the projection range of the inner mold structure 13 .

[0074] That is to say, the projection range of the net tail 14 completely falls within the projection range of the inner mold structure 13, that is, the projection of the part of the net tail 14 extending into the shell assembly 15 and the part of the net tail 14 outside the shell assembly 15 are both located within the projection of the inner mold structure 13. In this way, the size of the net tail 14 outside the shell assembly 15 can be smaller, thereby increasing the appearance reliability of the connector 1.

[0075] In some embodiments, the housing assembly 15 , the mesh tail 14 , and the inner mold structure 13 are all circular in cross-sectional shape in a direction perpendicular to the extension direction of the electrical terminal 102 , and are coaxially arranged.

[0076] The coaxial arrangement of the shell assembly 15 , the net tail 14 and the inner mold structure 13 means that after the shell assembly 15 , the net tail 14 and the inner mold structure 13 are assembled, the axes of the shell assembly 15 , the net tail 14 and the inner mold structure 13 coincide with each other.

[0077] In this embodiment, the shape setting of the shell assembly 15, the net tail 14 and the inner mold structure 13, on the one hand, facilitates the docking of the shell assembly 15, the net tail 14 and the inner mold structure 13, increases the connection convenience of the various components of the connector 1, and increases the appearance of the connector 1. On the other hand, when plugging and unplugging the connector 1, it is convenient for the operator to hold the net tail 14 for plugging and unplugging operations.

[0078] For some examples, see Figure 2 , Figure 4 and Figure 5 The inner mold structure 13 includes a main body section 131 and a connecting section 132. The connecting section 132 is located at one end of the main body section 131 close to the net tail 14. The outer diameter of the connecting section 132 is smaller than the outer diameter of the main body section 131. A step surface is formed at the connection between the connecting section 132 and the main body section 131. One end of the net tail 14 surrounds the outer circumference of the connecting section 132.

[0079] Specifically, the net tail 14 cooperates with the connecting section 132 to achieve docking with the inner mold structure 13. One end of the net tail 14 surrounds the outer circumference of the connecting section 132, that is, the outer diameter of the net tail 14 at the place where it cooperates with the connecting section 132 is larger than the outer diameter of the connecting section 132, so that the area of ​​the connection surface between the net tail 14 and the inner mold structure 13 can be increased, and the reliability of the combination of the two can be improved.

[0080] In some embodiments, the mesh tail 14 is connected to the step surface, so that the connection reliability between the mesh tail 14 and the inner mold structure 13 can be further improved.

[0081] The material of the inner mold structure 13 and the material of the net tail 14 can be the same or different.

[0082] For example, in some embodiments, the inner mold structure 13 is a hard plastic structure. The hard plastic structure has sufficient hardness and strength and is not easily deformed. The inner mold structure 13 can better wrap the connection part between the electrical terminal 102 and the wire 12, reduce the probability of damage to the connection part between the electrical terminal 102 and the wire 12, and increase the structural stability of the connector 1.

[0083] The net tail 14 is a soft plastic structure. The soft plastic structure is soft and can be deformed by force. When the connection between the connector 1 and other components needs to be disconnected, a force is applied to the net tail 14. The soft plastic structure can be appropriately bent and deformed under the pulling action while being convenient for the operator to hold the net tail 14, thereby reducing the probability of bending and breaking of the cable 11. For example, the net tail 14 can be made of thermoplastic polyurethane elastomer.

[0084] In some other embodiments, the inner mold structure 13 and the net tail 14 are an integrated soft plastic structure.

[0085] That is to say, the inner mold structure 13 and the mesh tail 14 can adopt an integrated structure, which further reduces the molding process of the connector 1 and increases the structural simplicity of the connector 1.

[0086] For some examples, see Figure 2 The shell assembly 15 has an installation opening 15a, the net tail 14 and the cable 11 are inserted into the installation opening 15a, and the outer diameter of the part of the net tail 14 located inside the shell assembly 15 is larger than the outer diameter of the installation opening 15a.

[0087] Specifically, the cable 11 is inserted into the installation opening 15a, the net tail 14 is covered on the outer periphery of one end of the cable 11 close to the electrical terminal structure 10, and is inserted into the installation opening 15a, and the outer diameter of the net tail 14 inside the shell assembly 15 is larger than the outer diameter of the installation opening 15a. When a force is applied to the net tail 14 toward one side of the cable 11 to disconnect the connector 1 from other components, the net tail 14 and the shell assembly 15 are subjected to force, reducing the probability of the inner mold structure 13 and the cable 11 being subjected to force. In addition, the part of the net tail 14 inside the shell assembly 15 cannot escape from the installation opening 15a, thereby increasing the structural reliability of the connector 1.

[0088] The outer diameter of the net tail 14 decreases in the direction away from the fixing seat 101. That is, the outer diameter of the net tail 14 inside the housing assembly 15 is greater than the outer diameter of the net tail 14 outside the housing assembly 15. In this way, while improving the pulling effect of the connector 1, the size of the part of the net tail 14 exposed to the outside can also be made smaller, which is more convenient for the miniaturization design of the connector 1 and improves the overall appearance performance of the connector 1.

[0089] For some examples, see Figure 1 and Figure 2 The housing assembly 15 includes a first shell 151 and a second shell 152. The first shell 151 and the second shell 152 are split structures. The first shell 151 and the second shell 152 are distributed along a first direction and clamp the overall structure formed by connecting the fixing seat 101, the inner mold structure 13, and the net tail 14 to achieve the fixation of the overall structure, wherein the first direction is parallel to the extension direction of the electrical terminal 102.

[0090] Specifically, the first shell 151 and the second shell 152 are split structures, that is, the first shell 151 and the second shell 152 are manufactured separately, and the first shell 151 and the second shell 152 can clamp the overall structure formed by the fixing seat 101, the inner mold structure 13, and the net tail 14 from both sides in the first direction to fix the overall structure, so that the overall structure and the shell assembly 15 are tightly matched along the first direction, and relative movement along the first direction will not occur. In addition, since the first shell 151 and the second shell 152 can be fixed when connected, no other connecting parts are needed to connect the shell assembly 15 and the overall structure, and the assembly is simple and reliable.

[0091] For some examples, see Figure 2 and Figure 4 The first shell 151 includes an outer shell 1511 and an inner shell 1512 arranged in the outer shell 1511. One end of the second shell 152 is inserted into the outer shell 1511 and connected to the inner shell 1512. The electrical terminal structure 10 and the inner mold structure 13 are accommodated in the inner shell 1512 and the second shell 152.

[0092] In this embodiment, through the cooperation of the outer shell 1511 and the inner shell 1512, while completing the docking with the second shell 152, the inner shell 1512 and the second shell 152 jointly provide a housing space for the electrical terminal structure 10 and the inner mold structure 13, so as to increase the housing reliability of the electrical terminal structure 10 and the inner mold structure 13, thereby increasing the structural stability of the connector 1.

[0093] The specific structure of the outer shell 1511 is not limited.

[0094] For some examples, see Figure 1 , Figure 2 and Figure 4The outer shell 1511 includes an insertion section 1511a and a receiving section 1511b. The outer diameter of the receiving section 1511b is larger than the outer diameter of the insertion section 1511a. The side wall of the insertion section 1511a is provided with a notch 1511c. The outer circumferential surface of the inner shell 1512 is provided with a stop hook 1512a. The stop hook 1512a extends to the outside of the side wall of the insertion section 1511a through the notch 1511c. The outer circumferential surface of the inner shell 1512 and the inner circumferential surface of the receiving section 1511b are spaced apart and form an annular groove 151a. One end of the second shell 152 extends into the annular groove 151a and is connected to the inner shell 1512.

[0095] In this embodiment, the setting of the stop hook 1512a can reduce the first shell 151 when docking with the second shell 152 and the overall structure formed by the electrical terminal structure 10, the inner mold structure 13 and the mesh tail 14, thereby increasing the docking stability. The outer diameter of the accommodating section 1511b is larger than the outer diameter of the plug-in section 1511a, which is convenient for providing an insertion space for the second shell 152 so that the second shell 152 can be inserted into the annular groove 151a between the inner shell sleeve 1512 and the accommodating section 1511b, so that one end of the second shell 152 can be confined between the inner shell sleeve 1512 and the accommodating section 1511b, thereby increasing the docking stability of the first shell 151 and the second shell 152.
