Description

Technical Field

[0001] This utility model relates to the field of waterproof connector structure technology, and specifically to a waterproof connector. Background Technology

[0002] A PIN probe connector is an electronic component used to transmit current or signals. Its core component is a PIN pin made of metal. When the mating contact surface of a PIN probe connector lacks a drainage structure, if the connector is in a humid environment or comes into contact with water, there is a risk of water accumulation on the mating contact surface, leading to short circuits or even complete short circuits in the PIN pins. To address this, some manufacturers have adopted measures such as adding small drainage holes to the mating contact surface and insulating the solder joints on the PIN pin soldering surface. However, this measure requires a high level of waterproofing at the solder joints. If there are gaps in the insulation protection of the solder joints, liquid can flow along the small drainage holes to the PIN pin solder joints, causing a short circuit.

[0003] Chinese invention patent document (CN104993298B) discloses a socket contact and connector assembly for underwater conductivity. The contact body has a through channel connecting the socket and the outside of the contact, serving as a drainage channel. However, the through channel of the socket contact is located on the socket wall and radially penetrates the wall, situated at the bottom of the socket. In other words, as shown in the accompanying drawings of this invention patent document, the drainage hole is located on the upper and lower sides of the contact body. This results in a weaker drainage effect for water accumulation in the middle, relying more heavily on the sealing and insulating component mentioned in the invention patent document to isolate the PIN pin from the liquid. Utility Model Content

[0004] This invention provides a waterproof connector to solve the problem that existing connectors have poor drainage performance in the middle of the mating contact surface.

[0005] To solve the above-mentioned technical problems, the present invention provides a waterproof connector, which includes: a connector base, a PIN pin group, a baffle, a water guiding part, and a drainage part.

[0006] The connector includes a first connector and a second connector that cooperate with each other, wherein the first connector is configured with a contact surface and a drainage surface on both sides along a first direction, respectively; the PIN pin group includes a plurality of PIN pins that pass through the first connector along the first direction; the baffle protrudes from the contact surface and divides the PIN pin group into at least two rows.

[0007] The water guiding part is located on the upper side of the baffle along the second direction, and includes a first guide protrusion and a second guide protrusion spaced apart along the third direction, wherein there is a gap between the first guide protrusion and the second guide protrusion and the baffle; the drainage part includes a drainage channel penetrating the first connecting seat along the first direction, wherein the first guide protrusion and the second guide protrusion are located on both sides of the drainage channel.

[0008] The beneficial effects of the technical solution provided by this utility model compared to the prior art are as follows:

[0009] By protruding baffles on the contact surface to isolate the PIN pin assembly, two physically separated drainage areas are formed for independent drainage. Specifically, water flow in the space occupied by the upper row of PIN pins can be guided laterally along the baffle. Due to the gap between the first and second guide protrusions and the baffle in the second direction, water flow can smoothly flow along the edge of the baffle, passing through the first or second guide protrusion and entering the drainage channel. When the waterproof connector is in normal use, water flow in the space occupied by the lower row of PIN pins can naturally flow out under gravity.

[0010] Compared to current connector drainage methods, the aforementioned arrangement, which concentrates the drainage structure (including the water guide and drainage sections) in the middle section of the connector, facilitates the rapid and effective drainage of water accumulated in the middle of the connector along the drainage channel. Furthermore, the water guide section, with its first and second guide protrusions working in tandem, guides the water flow longitudinally, assisting it to flow along either the first or second guide protrusion to the drainage channel and then to the drainage surface. By guiding all water flow to the drainage section, water accumulation at the solder joints of the PIN pins, preventing short circuits, is avoided. In other words, compared to conventional drainage structures, this design not only prevents short circuits caused by water accumulation at the PIN pins but also eliminates the need for additional special protection after soldering the PIN pins.

[0011] In some embodiments, the drainage section further includes a drainage column protruding from the drainage surface along the first direction, wherein the drainage channel sequentially passes through the first connector and the drainage column along the first direction. Further, the height of the drainage column protruding from the drainage surface along the first direction is greater than the height of any of the PIN needles protruding from the drainage surface along the first direction.

[0012] By adopting the above technical solution, the drainage channel is extended by the water guide column, so that when the water flows to the drainage surface (the back of the first connector), the water guide column can ensure that the water is discharged smoothly while avoiding the risk of water accumulating on the drainage surface, so as to prevent the water from flowing back and contaminating the solder joint of the PIN body.

[0013] In some embodiments, the water guiding part further includes a third guiding protrusion disposed at a distance between the first guiding protrusion and the second guiding protrusion along the third direction; wherein the third guiding protrusion forms a water guiding groove with the first guiding protrusion and the second guiding protrusion respectively, and the water guiding groove is connected to the drainage channel.

[0014] Using the above technical solution, the gaps between the water inlet groove and the adjacent PIN needles correspond, while the first and second guide protrusions can effectively utilize capillary action to adsorb the water film or water flow to the water inlet groove and then guide it to the drainage channel. Furthermore, the design of three guide protrusions allows for a larger design width of the drainage channel, thereby enhancing the drainage effect.

[0015] In some embodiments, the height of the third guide post protruding from the contact surface along the first direction is less than the height of the first guide post and the second guide post protruding from the contact surface along the first direction. Further, the third guide post at least partially embeds one of the PIN needles.

[0016] By adopting the above technical solution, water can be discharged from the gaps on both sides of the third guide post at the same time. Furthermore, the third guide post has a low height and is embedded with a PIN needle, which ensures that there is no space on the third guide post that could block water accumulation, thereby guaranteeing the drainage effect.

[0017] In some implementations, the baffle is at least partially embedded with a plurality of the PIN needles.

[0018] In some embodiments, the baffle protrudes above the contact surface in the first direction by a greater height than any of the PIN pins protrudes above the contact surface in the first direction.

[0019] By adopting the above technical solution, when the baffle is higher than the PIN body, the baffle of the first connector will first touch the second connector when the operator fastens the first connector and the second connector. In other words, adding a baffle can prevent the PIN body from being hit during the assembly process.

[0020] In some embodiments, the projection shapes of the first guide post and the second guide post along the first direction are L-shaped. Using the above technical solution, the L-shaped first and second guide posts can simultaneously guide the water flow in both the longitudinal and transverse directions.

[0021] In some embodiments, the first connector further includes a plurality of injection molding grooves corresponding one-to-one with the PIN needle body, wherein the PIN needle body passes through the corresponding injection molding groove, such that the injection molding groove can at least partially cover the PIN needle body. By injection molding to encapsulate the PIN needle body, deformation of the PIN needle body can be effectively prevented, and the structural strength of the PIN needle body can be improved.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0035] For ease of subsequent description, this application will first combine [the following descriptions] before describing the specific structure of the waterproof connector. Figure 1 A first direction (X), a second direction (Z), and a third direction (Y) are defined. The first direction is the length direction of the waterproof connector during normal use, such as the X direction; the second direction is the height direction of the waterproof connector during normal use, such as the Z direction; and the third direction is the width direction of the waterproof connector during normal use, such as the Y direction. In this application, the first direction (X), the second direction (Z), and the third direction (Y) are perpendicular to each other.

[0036] It is understood that the mutual perpendicularity in this application is not absolute perpendicularity. Approximate perpendicularity due to processing errors and assembly errors (e.g., the included angle between two structural features is 89.9°) is also within the scope of mutual perpendicularity in this application.

[0037] See Figures 1 to 3 As shown, Figure 1 This application provides a three-dimensional structural schematic diagram of an embodiment of a waterproof connector. Figure 2 This application provides a three-dimensional structural schematic diagram of an embodiment of the first connector 11 of a waterproof connector. Figure 1 ; Figure 3 This application provides a three-dimensional structural schematic diagram of an embodiment of the first connector 11 of a waterproof connector. Figure 2 ;in, Figure 1 The first connecting seat 11 and the second connecting seat 12 are in a locked state.

[0038] In some embodiments, the waterproof connector includes: a connector 10, a pin assembly 20, a baffle 30, a water-guiding portion 40, and a drainage portion 50. The connector 10 includes a first connector 11 and a second connector 12 that cooperate with each other, wherein the first connector 11 has a contact surface 110 and a drainage surface 111 respectively configured on both sides along a first direction; the pin assembly 20 includes a plurality of pin bodies 21 that penetrate the first connector 11 along the first direction; the baffle 30 protrudes from the contact surface 110 and divides the pin assembly 20 into at least two rows.

[0039] The water guiding part 40 is located on the upper side of the baffle 30 along the second direction, and includes a first guide protrusion 41 and a second guide protrusion 42 spaced apart along the third direction, wherein there is a gap between the first guide protrusion 41 and the second guide protrusion 42 and the baffle 30; the drainage part 50 includes a drainage channel 51 that passes through the first connecting seat 11 along the first direction, wherein the first guide protrusion 41 and the second guide protrusion 42 are located on both sides of the drainage channel 51.

[0040] In this embodiment of the application, combined with Figure 2 As shown, by protruding a baffle 30 on the contact surface 110 to isolate the PIN pin assembly 20, two physically separated drainage areas are formed for independent drainage. Exemplarily, water accumulated in the space where the upper row of PIN pins 21 is located can be laterally guided along the baffle 30. Because there is a gap between the first guide post 41 and the second guide post 42 and the baffle 30 in the second direction, water can flow smoothly along the edge of the baffle 30, passing through the first guide post 41 or the second guide post 42, and entering the drainage channel 51. Since the waterproof connector is affected by gravity during normal use, water accumulated in the space where the lower row of PIN pins 21 is located can naturally flow out under gravity.

[0041] The water guiding section 40 is equipped with a first guide protrusion 41 and a second guide protrusion 42. These protrusions effectively utilize capillary action to attract nearby water films, guiding the water flow longitudinally to the area above the baffle 30 and along the drainage channel 51 to the drainage surface 111. This prevents water accumulation at the solder joints of the PIN needle 21, which could cause short circuits. Compared to conventional drainage structures, this design not only avoids short circuits due to water accumulation in the PIN needle 21 but also eliminates the need for additional special protection (such as adding a sealing structure at the solder joint) after soldering the PIN needle 21.

[0042] In some embodiments, the first connector 11 further includes a plurality of injection molding grooves 112 corresponding one-to-one with the PIN needle body 21, wherein the PIN needle body 21 passes through the corresponding injection molding groove 112, so that the injection molding groove 112 can at least partially cover the PIN needle body 21. By injection molding to cover the PIN needle body 21, deformation of the PIN needle body 21 can be effectively prevented, and the structural strength of the PIN needle body 21 can be improved.

[0043] In some embodiments, the drainage section 50 further includes a drainage column 52 protruding from the drainage surface 111 along a first direction, wherein the drainage channel 51 sequentially passes through the first connecting seat 11 and the drainage column 52 along the first direction. Exemplarily, combined with... Figure 4 As shown, Figure 4 This illustration shows a top view of an embodiment of a first connector base 11 of a waterproof connector provided in this application. The height of the drainage column 52 protruding from the drainage surface 111 in a first direction is greater than the height of any PIN pin 21 protruding from the drainage surface 111 in the first direction.

[0044] In this embodiment, the drainage channel 51 is extended by the water guide column so that when the water flows to the drainage surface 111 (i.e. the back side of the first connector 11), the water guide column can ensure that the water is discharged smoothly while avoiding the risk of water accumulating on the drainage surface 111, so as to prevent the water from flowing back and contaminating the soldering point of the PIN needle body 21.

[0045] In some implementation schemes, combined Figure 4 As shown, the height of the baffle 30 protruding from the contact surface 110 in the first direction is greater than the height of any PIN pin protruding from the contact surface 110 in the first direction.

[0046] In this embodiment, when the baffle 30 is higher than the PIN needle body 21, the baffle 30 of the first connecting seat 11 will preferentially contact the second connecting seat 12 when the operator fastens the first connecting seat 11 and the second connecting seat 12. In other words, adding the baffle 30 can prevent the PIN needle body 21 from being hit during the assembly process, thereby improving the service life of the PIN needle body 21.

[0047] See Figures 5 to 6 As shown, Figure 5 A front view of an embodiment of a first connector 11 of a waterproof connector provided in this application is shown; Figure 6 for Figure 5 The flow guidance diagram; among which, Figure 5 The arrows in the diagram indicate the direction of water flow.

[0048] In some embodiments, the first guide post 41 and the second guide post 42 have an L-shaped projection along the first direction. In the embodiments of this application, the L-shaped first guide post 41 and the second guide post 42 can simultaneously guide the water flow in both the longitudinal and transverse directions, combined with Figure 6 As shown, the L-shaped first guide post 41 and second guide post 42 can also match the edge shape of the drainage channel 51.

[0049] In some embodiments, the water guiding part 40 further includes a third guiding protrusion 43 disposed at a distance in a third direction between the first guiding protrusion 41 and the second guiding protrusion 42; wherein the third guiding protrusion 43 forms a water guiding groove 44 with the first guiding protrusion 41 and the second guiding protrusion 42 respectively, and the water guiding groove 44 is connected to the drainage channel 51.

[0050] For example, Figure 5 The diagram shows PIN needles 21 numbered 1 to 6, and PIN needles 21 located on either side of PIN needles 21 numbered 1 to 6. PIN needles 21 numbered 1 to 6 can be signal PINs, and the PIN needles 21 located on either side of the signal PINs can be power PINs. In this embodiment, the water channel 44 corresponds to the gap between adjacent PIN needles 21. Simultaneously, the first guide protrusion 41 and the second guide protrusion 42 can effectively utilize capillary action to adsorb the water film or water flow to the water channel 44 and then guide it to the drainage channel 51.

[0051] In some application scenarios, the water channel 44 can also be represented as the gap between the first guide post 41 and the baffle 30, and the gap between the second guide post 42 and the baffle 30. The design of three guide posts can make the designable width of the drainage channel 51 larger, so as to enhance the drainage effect.

[0052] See Figure 7 As shown, Figure 7 This application provides a three-dimensional structural schematic diagram of an embodiment of the first connector 11 of a waterproof connector. Figure 3 ;in, Figure 7 The PIN needle 21 has been hidden.

[0053] In some embodiments, the height of the third guide protrusion 43 protruding from the contact surface 110 along the first direction is less than the height of the first guide protrusion 41 and the second guide protrusion 42 protruding from the contact surface 110 along the first direction. Further, the third guide protrusion 43 at least partially embeds a PIN needle body 21.

[0054] In this embodiment, by setting the third guide post 43 to a lower height, it can better match the embedded PIN needle 21, thus eliminating any space in the third guide post 43 that could block water accumulation and ensuring drainage. Furthermore, the PIN needle 21 is at least partially embedded in the third guide post 43, which can wrap around one side of the PIN needle 21, improving its structural strength. Exemplarily, the first guide post 41 and the second guide post 42 also at least partially embed the PIN needle 21, so that the sides of the corresponding PIN needle 21 are wrapped, thereby improving the structural strength of the corresponding PIN needle 21.

[0055] In some embodiments, the baffle 30 is at least partially embedded with a plurality of PIN pins 21. Different PIN pins 21 are embedded in the baffle 30, the first guide post 41, the second guide post 42, and the third guide post 43 respectively to ensure the structural strength of any PIN pin 21, thereby avoiding deformation of the PIN pin 21 and improving the service life of the connector.

[0056] See Figures 8 to 9 As shown, Figure 8 This invention provides a three-dimensional structural schematic diagram of an embodiment of the second connector 12 of a waterproof connector. Figure 9 A cross-sectional view of a waterproof connector provided in this application is shown.

[0057] For example, the second connector 12 is provided with a plurality of pin slots 120 that match the PIN pin body 21, so that when the first connector 11 and the second connector 12 are interlocked, signal and electrical conduction is achieved. Wherein, as Figure 9 As shown, when the first connecting seat 11 and the second connecting seat 12 are engaged, the water accumulated on the contact surface 110 can be guided by the water guiding part 40 and flow out along the drainage channel 51.

[0058] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, should be included within the protection scope of this utility model.
