Description

Technical Field

[0001] The present application relates to the technical field of electrical connectors, and more specifically, to sockets, connectors and devices. Background Art

[0002] Connectors are electrical connection components commonly found on agricultural machinery, automobiles, engineering machinery and other equipment or devices. They are used to connect line ports to ports on circuit boards. Connectors generally include plugs and sockets. The sockets are generally located on circuit boards, and the plugs are generally located on line ports. With the improvement of electrical integration, wiring harnesses composed of multiple ports can be combined to form an interface, and the plugs and sockets of the interface can form a connector.

[0003] During the operation of mechanical devices such as agricultural machinery and automobiles that operate or work outdoors, there may be impurities such as water and dust in the working environment. These impurities may enter the electrical interface of the connector and may cause faults such as short circuits. Therefore, these connectors will include some sealing structures or perform certain sealing treatments to prevent water and dust from entering. However, the sealing structure between the plug and the socket will increase the resistance of the plug to plug and unplug, which may make it difficult to plug and unplug the plug.

[0004] In view of this, how to reduce the plug-in and pull-out resistance of a connector with a waterproof function and reduce the plug-in and pull-out difficulty phenomenon is an issue that needs to be solved urgently. Summary of the invention

[0005] The present application provides a socket, a connector and a device, which can reduce the resistance during the plug-in and plug-out process.

In addition, since there is no need to consider the difficulty of plug-in and pull-out, a higher level of sealing can be designed between the plug and the socket, further reducing the possibility of the connection column inside the socket being exposed to external impurities such as water and dust, thereby improving the waterproof performance of the connector.

[0013] The technical solution provided in the present application provides a relatively optimal aspect ratio of the socket protrusion, which can make the socket protrusion have a certain strength, thereby reducing the probability of the socket protrusion breaking.

[0016] In combination with the first aspect, in some implementations of the first aspect, a ratio of a cross-sectional area of ​​an inner cavity of the socket to a cross-sectional area of ​​a through hole of the socket is less than or equal to 500 and greater than or equal to 20.

[0017] The technical solution provided in the present application limits the ratio range of the cross-sectional area of ​​the inner cavity of the socket to the cross-sectional area of ​​the through hole of the socket, which can ensure lower resistance when the plug is plugged in and out, and reduce the possibility of water, dust, etc. entering the inner cavity of the device through the through hole of the socket, thereby improving the sealing of the device.

[0044] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0045] In the present application, the methods, situations, categories and divisions of the embodiments in each application embodiment are only for the convenience of description and should not constitute special limitations. The features of various methods, categories, situations and embodiments can be combined without contradiction.

[0046] It should be understood that "multiple" in the application embodiments refers to two or more. The term "and / or" is used to describe the association relationship of associated objects, indicating that three relationships may exist; for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0047] The directional terms mentioned in the embodiments of the present application, such as "up", "down", "left", "right", "inside", "outside", etc., are only references to the directions of the drawings. Therefore, the directional terms used are for better and clearer description and understanding of the embodiments of the present application, rather than indicating or implying that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application. "Along the direction of..." is not in a strict sense, but within the tolerance range.

[0048] In the description of the embodiments of the present application, the term "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article, or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article, or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or device including the element.

[0049] The present application relates to the technical field of electrical connectors. The socket may be an electrical connector with waterproof or dustproof function, and may be a plug-in wire-to-board connector, an elastic contact wire-to-board connector, a lead wire-to-board connector, a spring wire-to-board connector, etc. The socket may be applied to a variety of fields and scenarios. As an example, the socket may be a socket for electrical connection of equipment or devices such as agricultural machinery, automobiles, and engineering machinery. These equipment or devices require certain waterproof or dustproof treatments for their electrical components and connectors, such as wire-to-board connectors, to prevent impurities in the working environment from entering the equipment or contacting the electrical components or connectors, thereby affecting the operation of the electrical components.

[0050] An embodiment of the present application provides a socket, which is arranged on a connecting plate of a device, and the connecting plate is provided with a connecting plate through hole, including a socket through hole, an isolation shell and a connecting column.

[0051] Figure 1 and Figure 2 A socket provided in an embodiment of the present application is shown. Figure 2 yes Figure 1 A cross-sectional view of a socket is shown. Figure 2 As shown, the socket includes a socket through hole 111, which connects the socket inner cavity 113 and the connecting plate through hole; an isolation shell 112, which is used to abut against the plug through the isolation shell inner wall 114 facing the socket inner cavity 113 to isolate the socket inner cavity 113 from the outside; a connecting column 115, which is located inside the socket 110, and is used to electrically connect the circuit interface of the device with the plug.

[0052] For better expression Figure 1 and Figure 2 The socket in Figure 3 The figure shows the assembly diagram of the socket, plug and device. Figure 3 As shown, the plug 120 is connected with the socket 110, wherein the plug 120 may include an isolation ring 121, and the isolation shell inner wall 114 inside the isolation shell 112 abuts against the isolation ring 121 surrounding the plug 120 to isolate the socket inner cavity 113 of the socket 110 from the outside. The socket 110 is connected with the device 130, wherein a connection plate through hole 131 is provided in the connection plate on the upper side of the device 130, and the connection plate through hole 131 is coaxially connected with the socket through hole 111, so as to connect the socket inner cavity 113 with the inner cavity of the device 130. The connection column 115 is used to connect the plug 120 with the circuit interface inside the device 130.

[0053] When the plug 120 is inserted into the socket 110, the air in the socket cavity 113 flows to the inner cavity of the device 130 through the socket through hole 111 and the connecting plate through hole 131, which can reduce the insertion resistance caused by the compression of the air in the socket cavity 113; when the plug 120 is pulled out of the socket 110, the air in the inner cavity of the device 130 flows to the socket cavity 113 through the connecting plate through hole 131 and the socket through hole 111, which can reduce the pull-out resistance caused by the decrease in air pressure in the socket cavity 113.

[0054] The technical solution of the embodiment of the present application opens a through hole on the connection plate of the socket and the device, connects the inner cavity of the socket with the inner cavity of the device, and allows the air in the inner cavity of the socket to flow through the through hole during the plug insertion and removal process, thereby reducing the resistance during the plug insertion and removal process. In addition, since there is no need to consider the difficulty of plugging and removal, a higher level of sealing can be designed between the plug and the socket, further reducing the possibility of the connection column inside the socket contacting external impurities such as water and dust, thereby improving the waterproof performance of the connector.

[0055] Optionally, the socket further includes a socket protrusion, the socket through hole is located in the middle of the socket protrusion, the socket protrusion is located in the connecting plate through hole of the connecting plate, and the socket is connected to the connecting plate through hole of the device via the socket protrusion.

[0056] Figure 4 is a partial cross-sectional view of a socket provided by the present application. Figure 4 As shown, the socket 410 has a socket protrusion 412 below, and the middle of the socket protrusion 412 is a socket through hole 411. The connecting plate of the device 420 has a connecting plate through hole 421. The socket protrusion 412 is located in the connecting plate through hole 421 to connect the socket 410 with the connecting plate through hole 421.

[0057] The technical solution provided in the embodiment of the present application can achieve the positioning and / or fixation of the socket and the device through the matching connection between the socket protrusion and the connecting plate through hole, and the socket protrusion can also seal around the connecting plate through hole, thereby improving the waterproof and dustproof performance of the device.

[0058] Optionally, a ratio of a height of the socket protrusion of the socket to an outer diameter of the socket protrusion is less than or equal to 5.

[0059] Figure 4 The height of the socket protrusion 412 is H, and the outer diameter of the socket protrusion is D. When the ratio of H to D is greater than 5, the strength of the socket protrusion 412 is reduced, and the socket protrusion 412 is easily broken under the action of external force. When the ratio of H to D is less than or equal to 5, the strength of the socket protrusion 412 is relatively sufficient, which can reduce the probability of the socket protrusion 412 breaking under the action of external force.

[0060] The technical solution provided in the embodiment of the present application provides a relatively optimal aspect ratio of the socket protrusion, which can make the socket protrusion have a certain strength, thereby reducing the probability of the socket protrusion breaking.

[0061] Optionally, the socket is connected to the protrusion on the connecting plate through the socket through hole, the protrusion is located in the socket through hole, and the connecting plate through hole is located in the middle of the protrusion.

[0062] Similarly, Figure 4 The raised portion shown in the embodiment may also be located at the upper part of the device connection plate. For example, the connection plate may be provided with a connection plate raised portion, the connection plate through hole is located in the middle of the connection plate raised portion, the socket is connected to the connection plate raised portion through the socket through hole, and the connection plate raised portion is located in the socket through hole. The connection plate raised portion at the upper part of the connection plate may have similar features to the above-mentioned socket raised portion, and may have similar technical effects to the above-mentioned socket raised portion.

[0063] The technical solution provided in the embodiment of the present application connects the socket and the device connecting plate through a protruding structure located on the socket or on the device connecting plate, thereby realizing the positioning and / or fixing of the socket and the device, and can also seal around the through hole of the connecting plate, thereby improving the waterproof and dustproof performance of the device.

[0064] Optionally, a diameter of the socket through hole of the socket is greater than or equal to 0.8 millimeters (mm).

[0065] Figure 4 The aperture of the socket through hole 411 is d. When d is greater than or equal to 0.8 mm, the speed of air flowing through the socket through hole 411 is moderate, and the difficulty of processing or manufacturing the socket through hole 411 is low. When d is less than 0.8 mm, the speed of air flowing through the socket through hole 411 is slow, the resistance of plugging and unplugging the plug is large, and the difficulty of processing or manufacturing the socket through hole 411 is high.

[0066] The technical solution provided in the embodiment of the present application limits the aperture of the socket through hole, and can provide a socket through hole with less resistance when the plug is inserted and removed and with lower processing or manufacturing difficulty.

[0067] Optionally, a ratio of a hole depth to a hole diameter of the socket through hole of the socket is less than or equal to 5.

[0068] Figure 4 The hole depth of the socket through hole 411 is h. When the ratio of h to d is less than or equal to 5, the processing or manufacturing difficulty of the socket through hole 411 is relatively low. When the ratio of h to d is greater than 5, the processing or manufacturing difficulty of the socket through hole 411 is large, and the resistance of air flowing through the socket through hole 411 is relatively large.

[0069] The technical solution provided in the embodiment of the present application limits the ratio of the hole depth to the hole diameter of the socket through hole, which can reduce the difficulty of processing or manufacturing the socket through hole, and can reduce the resistance of air flowing through the socket through hole, thereby reducing the plug-in and plug-out resistance.

[0070] Optionally, the ratio of the cross-sectional area of ​​the socket inner cavity to the cross-sectional area of ​​the socket through hole is less than or equal to 500 and greater than or equal to 20. The socket inner cavity cross-sectional area is a cross-sectional area perpendicular to the plug insertion direction of the socket inner cavity, and the socket through hole cross-sectional area is a cross-sectional area perpendicular to the socket through hole and the extension direction of the socket through hole.

[0071] Figure 5 This is a view of a socket provided by the present application along the plug insertion direction. For example, Figure 5 Can be Figure 1 The top view of the socket shown in FIG. The direction of the socket through hole can be parallel or non-parallel to the direction in which the plug is inserted into the socket. For ease of expression, Figure 5The direction of the socket through hole is parallel to the direction in which the plug is inserted into the socket. When the plug is inserted into the socket, the air in the socket cavity 512 flows to the device cavity through the socket through hole 511. When the speed at which the plug is inserted into the socket is fixed, the larger the ratio of the cross-sectional area of ​​the socket cavity to the cross-sectional area of ​​the socket through hole, for example, the ratio increases from 500 to 2000, the slower the flow rate of air through the socket through hole 511, and the greater the resistance of the plug to the socket. The smaller the ratio of the cross-sectional area of ​​the socket cavity to the cross-sectional area of ​​the socket through hole, for example, the ratio decreases from 20 to 5, the larger the cross-sectional area of ​​the socket through hole, and it is easier for water, dust, etc. to enter the device cavity through the socket through hole, which may cause problems such as short circuits.

[0072] The technical solution provided in the embodiment of the present application limits the ratio range of the cross-sectional area of ​​the inner cavity of the socket to the cross-sectional area of ​​the through hole of the socket, which can ensure lower resistance when the plug is plugged in and out, and reduce the possibility of water, dust, etc. entering the inner cavity of the device through the through hole of the socket, thereby improving the sealing of the device.

[0073] Optionally, an isolation ring is provided on the plug, and the socket abuts against one or more isolation ring protrusions on the isolation ring through the isolation shell.

[0074] Figure 6 A socket and a plug connected therewith provided in an embodiment of the present application are shown. Figure 6 As shown, the plug is surrounded by an isolating ring 610. The isolating ring 610 has one or more isolating ring protrusions 611. When the plug is inserted into the socket, the isolating ring protrusions 611 are squeezed and deformed, and under the action of the internal stress generated by the deformation, they abut against the inner wall of the socket isolation shell and are pressed tightly, thereby isolating and sealing the inner cavity of the socket from the outside. The isolating ring protrusions 611 may include one or more circles. The plug also has an interface inside to electrically connect with the connecting column inside the socket.

[0075] The technical solution provided in the embodiment of the present application isolates the inner cavity of the socket from the outside world by isolating the inner cavity of the socket from the outside world through one or more circles of protrusions on the isolation shell and the isolation ring, thereby reducing the possibility of water and dust entering the inner cavity of the socket, reducing the probability of faults such as short circuits in the connector, and improving the operating stability and electrical connection safety of the connector.

[0076] Optionally, the isolation ring may be made of rubber material.

[0077] Optionally, a plug flange protruding in a radial direction is provided on the plug, and when the socket is connected to the plug, an edge of the isolation shell of the socket abuts against the plug flange.

[0078] Figure 7 The present application shows a socket and a plug that is connected thereto. Figure 7As shown, the socket 710 includes an isolation shell 711, and the plug 720 includes a plug flange 721. The edge 712 of the isolation shell 711 is parallel to and opposite to the lower side 722 of the plug flange 721. When the socket 710 and the plug 720 are connected, the edge 712 abuts against the lower side 722 to isolate the inner wall of the isolation shell from the outside.

[0079] The technical solution of the embodiment of the present application isolates the inner wall of the isolation shell from the outside world through the plug flange, reduces the possibility of water or dust entering the inner cavity of the socket during the plugging and unplugging process, and further improves the sealing performance of the connector.

[0080] Optionally, the socket and the plug are connected by a snap-fit ​​connection.

[0081] For example, the socket may include a female buckle to snap-fit ​​with a male buckle of the plug.

[0082] Figure 8 A socket and a plug connected therewith provided in an embodiment of the present application are shown. Figure 8 As shown, the outer wall of the isolation shell of the socket 810 is provided with a female buckle 811, and the plug is provided with a male buckle 821. When the socket 810 is connected with the plug 820, the female buckle 811 and the male buckle 821 are snap-connected to fix the socket 810 and the plug 820.

[0083] The technical solution of the embodiment of the present application connects the socket and the plug by means of a snap connection, which can improve the stability of the connection.

[0084] Optionally, the socket and the plug can be connected by means of a lock, a threaded structure, etc., or after being connected, they can be fixed by means of a lock, a threaded structure, etc.

[0085] In order to improve the waterproof performance, the device may be sealed. After the sealed device is connected to the connector, the inner cavity of the device is isolated from the outside world. When the circuit inside the device is running and heating up, the air pressure in the inner cavity of the device will increase due to the temperature rise, which may generate pressure or thrust on the plug in the socket through the socket through-hole, causing the plug to tend to be pushed outward.

[0086] In order to reduce the problem of pressure increase of the air in the inner cavity of the above-mentioned device due to temperature increase, the socket may optionally further include a switch structure, and when the switch structure is closed, the through hole of the socket is closed.

[0087] Optionally, the function of the switch structure can be implemented by a variety of structures. For example, the switch structure can be a switch pin.

[0088] Fig. 9 A socket with a switch structure provided by the present application is shown. Fig. 9As shown, the socket includes a switch pin 912 as a switch structure. When the switch pin 912 completely enters the socket through hole 913, that is, the switch structure is closed, the switch pin 912 closes the socket through hole 913, and the air cannot flow between the socket inner cavity 911 and the through hole outlet 914 through the socket through hole 913. When the switch pin 912 withdraws from the socket through hole 913, that is, the switch structure is opened, the socket through hole 913 is opened, and the air can flow between the socket inner cavity 911 and the socket through hole outlet 914 through the socket through hole 913.

[0089] During the plug insertion and removal process, the switch pin 912 is pulled out to open the socket through hole 913. When the plug is connected to the socket, the switch pin 912 can be pushed into the socket to close the switch structure, so that air cannot circulate through the socket through hole 913. When the device is running, the air pressure inside the closed device will increase due to the heat generated by the internal circuit. At this time, if the switch structure is closed, the air entering the socket cavity 911 through the socket through hole 913 can be reduced, reducing the force on the plug that pushes the plug outward. When the plug is not connected to the socket, the socket cavity 911 is exposed to the outside. At this time, the switch structure can be closed to reduce water or dust from entering the lower device through the socket through hole 913.

[0090] The technical solution of the embodiment of the present application can control the opening or closing of the through hole by introducing a switch structure. When the device is running and heating up, the switch structure can prevent the plug from being pushed out of the socket due to the thermal expansion of the air inside the device. The switch structure can also reduce the entry of water or dust into the device from the inner cavity of the socket.

[0091] Optionally, in some technical solutions provided in the embodiments of the present application, a groove structure is provided on the side of the switch pin.

[0092] For example, the switch pin can be Fig. 9 The middle switch pin 912 has a groove on the side. When the switch structure needs to be opened, the switch pin 912 can be pulled out through the groove structure.

[0093] In this way, it is convenient to take out the switch pin to open the switch structure and open the socket through hole.

[0094] Optionally, the switch structure of the socket can be automatically turned off after the socket is connected to the plug.

[0095] For example, in some technical solutions provided in the embodiments of the present application, the bottom of the switch pin serving as the switch structure may have a spring, and when the socket is connected to the plug through a snap-fit, the snap-fit ​​presses the switch pin in to close the switch structure.

[0096] Fig.10 is a schematic structural diagram of a socket with a switch structure that automatically turns off after connection provided by an embodiment of the present application. Fig.10 As shown, the socket 1020 includes a female buckle 1021, which is used to connect with the male buckle structure 1011 of the plug connection structure 1010. When the socket 1020 is connected to the plug, the female buckle 1021 and the male buckle structure 1011 are snap-connected. The connection structure 1010 also includes a pressing structure 1012. When the plug is connected, the pressing structure 1012 presses the switch pin 1022 to close the socket through hole.

[0097] When a plug is inserted into the socket 1020, the switch structure may be automatically opened. Fig.11 yes Fig.10 A partial enlarged view of the switch structure in FIG. Fig.11 As shown, the socket through hole includes a spring groove 1024, and the spring groove 1024 contains a spring 1025. When the plug is connected, the pressing structure 1012 abuts against the pressing surface 1023 on the top of the switch pin 1022, pressing the switch pin 1022 in to close the switch structure. When the plug is not connected, the spring 1025 pushes the switch pin 1022 outward from the socket, thereby opening the switch structure and opening the socket through hole.

[0098] The technical solution of the embodiment of the present application can automatically close the socket through hole when the socket is connected to the plug, thereby simplifying the operation.
