Description

Technical Field

[0001] The utility model relates to the technology of connecting wire field, in particular to a double waterproof connecting wire and an electronic product. Background Art

[0002] Connectors have been widely used. When the male and female connectors are plugged into each other, the waterproof requirements at the plug-in point have always been a focus of attention, especially when they need to be used in humid environments or outdoor environments.

[0003] CN117559160A The invention discloses a line-to-line waterproof connector, which relates to the technical field of connectors, and comprises a data line male head and a data line female head matched with the data line male head. The data line female head is provided with a connecting mechanism, and the connecting mechanism comprises a connecting cylinder, a limiting frame and four connecting pieces, and also comprises a fixing mechanism, and the fixing mechanism comprises a fixing frame, an extrusion frame, a sealing ring and four limiting blocks. The fixing frame is fixed on the outer wall of the data line male head, and the extrusion frame is fixed on the outer wall of one end of the fixing frame, the sealing ring abuts on the outer wall of one side of the extrusion frame, and the sealing ring is sleeved on the outer wall of the data line male head, and the four limiting blocks are respectively fixed on the fixing frame away from the extrusion frame. On one side outer wall, two limit mechanisms are provided on one side of the fixed frame, and the limit mechanisms include a pressing plate, two limit rods, two extrusion rods, two extrusion blocks, two limit cylinders and two return springs, the two limit rods are respectively fixed on the outer walls at both ends of the top of the pressing plate, and the two limit rods respectively penetrate and are slidably installed on the top outer walls of the two limit blocks, the two extrusion rods are respectively fixed on the bottom outer wall of the pressing plate, and the two extrusion blocks are respectively fixed on the outer walls of the bottom ends of the two extrusion rods, the two limit cylinders are respectively fixed on the outer walls of the male head of the data cable, and the two extrusion blocks are respectively slidably installed in the two limit cylinders, and the two return springs are respectively sleeved in the two limit cylinders.

[0004] When the male and female ends of the data cable are assembled, the sealing ring is fixed on the extrusion frame with sealant, and the two pressing plates are pressed with fingers. The pressing plates drive the two extrusion rods to compress the reset spring. At this time, the limit rod drops. After the male and female ends of the data cable are plugged in, the connecting piece overlaps with the limit block, and then the pressing plate is released. The pressing plate and the two limit rods reset the limit rod under the action of the reset spring tension. Then the limit rod is plugged into the connecting piece to fix the connecting tube and the fixing frame, and at the same time fix the male and female ends of the data cable to prevent them from loosening. The fixing frame and the extrusion frame are sleeved in the connecting tube. At this time, the limit frame contacts and squeezes the sealing ring to prevent external moisture from entering the male and female ends of the data cable.

[0005] This structure is relatively complicated, and the operation is troublesome when assembling the male connector of the data cable and the female connector of the data cable.

[0006] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0035] Please refer to Figures 1 to 10 As shown, it shows the specific structure of an embodiment of the utility model.

[0036] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0037] A double waterproof connection cable includes a male data cable 100 and a female data cable 200 which are adapted to be plugged into each other.

[0038] The male data cable 100 includes a male connector 101, a first wire body 102, a first insulating inner mold 103, a first insulating outer mold 104 and a first waterproof sealing ring 105; the male connector 101 is connected to the first wire body 102, the first insulating inner mold 103 is injection molded and fixed at the connection between the male connector 101 and the first wire body 102, and the first insulating outer mold 104 is injection molded and fixed to the outside of the male connector 101, the first insulating inner mold 103 and the first wire body 102; the outer peripheral surface of the first insulating outer mold 104 is concavely provided with an annular mounting groove 1041; the first waterproof sealing ring 105 is located in the annular mounting groove 1041 and protrudes from the outer periphery of the first insulating outer mold 104.

[0039] The female data cable 200 includes a female connector 201, a second wire body 202, a second insulating inner mold 203 and a second insulating outer mold 204; the female connector 201 is connected to the second wire body 202, the second insulating inner mold 203 is injection molded and fixed at the connection between the female connector 201 and the second wire body 202, the second insulating outer mold 204 is injection molded and fixed to the outside of the female connector 201 and the second insulating inner mold 203, and the second insulating outer mold 204 extends beyond the plug-in interface of the female connector 201 to form a sealed cavity 2041.

[0040] The male connector 101 is inserted into the female connector 201, and the second insulating outer mold 204 is wrapped around the outer periphery of the first waterproof sealing ring 105 to form a radial sealing contact, and a second waterproof sealing ring 30 is arranged between the first insulating outer mold 104 and the inner surface of the sealing cavity 2041 to form an axial sealing contact.

[0041] Specifically, Figures 1 to 7As shown, it shows the structure of the first embodiment; a double waterproof connection line, including a male data line 100 and a female data line 200 that are mutually adapted and plugged. In this article, the TYPE-C data line is used as an example for explanation. In actual design and production, it is not limited to this type of data line, and other interface types can also be used.

[0042] The male data cable 100 includes a male connector 101, a first wire body 102, a first insulating inner mold 103, a first insulating outer mold 104 and a first waterproof seal ring 105. During production, the rear PCB board of the male connector 101 is first connected to the first wire body 102, and then the first insulating inner mold 103 is used to wrap the connection part of the PCB board and the first wire body 102 for injection molding, and then the second insulating outer mold 204 is used to fix the connection part of the PCB board and the first wire body 102 for injection molding. 4 is wrapped and fixed to the tail end of the male connector 101, the outside of the first insulating inner mold 103 and the end of the first wire body 102; usually the first insulating inner mold 103 can be made of a harder plastic material, and the first insulating outer mold 104 can be made of a relatively soft plastic material; the first insulating outer mold 104 is used to form a tail buckle part that connects the wire body and the male head in the traditional technology, which plays a better protection role for the first wire body 102, is not easy to break and damage, and does not require a separate process to form the tail buckle part. The male connector 101 includes a hidden section buried in the first insulating outer mold 104 and a plug-in section exposed outside the first insulating outer mold 104. The outer peripheral surface of the first insulating outer mold 104 is concavely provided with an annular mounting groove 1041, and the annular mounting groove 1041 is extended around the outer periphery of the hidden section. The front and rear ends of the first insulating outer mold 104 corresponding to the annular mounting groove 1041 are respectively reserved with a front groove wall and a rear groove wall to play a front and rear limit role for the first waterproof sealing ring 105. The head end of the first insulating outer mold 104 retains an annular pressing end 1042 located at the outer end of the annular mounting groove 1041; usually, the peripheral edge of the annular pressing end 1042 is designed as a guiding slope or a guiding arc surface, which is convenient for the first waterproof sealing ring 105 to be inserted from the head end of the male data cable 100. The first waterproof sealing ring 105 will be enlarged and deformed during the insertion process. When reaching the annular mounting groove 1041, the first waterproof sealing ring 105 falls into the annular mounting groove 1041, recovers the deformation or is slightly enlarged compared to the natural state (that is, the inner hole of the first waterproof sealing ring 105 is slightly enlarged by the inner bottom surface of the annular mounting groove 1041), which is conducive to the first waterproof sealing ring 105 being firmly positioned in the annular mounting groove 1041 and not easy to loosen. The first waterproof sealing ring 105 is located in the annular installation groove 1041. Two or more sealing convex rings 1051 are convexly arranged on the outer periphery of the first waterproof sealing ring 105. The sealing convex rings 1051 are arranged at intervals along the plugging direction, and all the sealing convex rings 1051 are extended around the outer periphery of the hidden section. The sealing convex rings 1051 are exposed on the outer periphery of the first insulating outer mold 104. More than two sealing convex rings 1051 can play a multiple sealing role.

[0043] The female data cable 200 includes a female connector 201, a second wire body 202, a second insulating inner mold 203, a tail buckle 205, a second insulating outer mold 204 and a second waterproof seal ring 30. During production, the rear end PCB board of the female connector 201 is first connected to the second wire body 202, and then the second insulating inner mold 203 is used to wrap the connection part of the PCB board and the second wire body 202 by injection molding, and wraps most of the peripheral area of ​​the female connector 201, at least extending to wrap more than half of the length of the female connector 201, and then the second injection molding is performed, and the tail end of the second insulating inner mold 203 is connected to the second insulating outer mold 204. A tail buckle 205 is formed at the junction of the two wire bodies 202. Here, a stop groove 2031 is provided on the second insulating inner mold 203. When the tail buckle 205 is injection molded at the connection between the tail end of the second insulating inner mold 203 and the second wire body 202, the tail buckle 205 fills the stop groove 2031 and is wrapped around the outside of the second wire body 202. In this way, the bonding strength between the tail buckle 205 and the first insulating inner mold 103 is improved. Furthermore, a stop convex portion 2051 is provided on the periphery of the tail buckle 205. Then, the second insulating outer mold 204 is obtained by the third injection molding. The second insulating outer mold 204 is wrapped around the tail buckle 205, the second insulating inner mold 203 and the periphery of the female connector 201. The second insulating outer mold 204 is limited by the front side of the stop convex portion 2051, which effectively prevents the second insulating outer mold 204 from being displaced and loosened toward the tail end of the second wire body 202. At the head end of the second insulating outer mold 204, the inner wall surface facing the outer end is sequentially provided with the first inner hole wall 1, the second inner hole wall 2 and the third inner hole wall 3. A small length of annular groove 4 is reserved between the first inner hole wall and the outer periphery of the head end of the metal shell of the female connector 201, and the first inner hole wall extends outward beyond the female connector 201. The second inner hole wall is located outside the first inner hole wall, so that an annular step wall 5 is connected between the second inner hole wall and the first inner hole wall, and the third inner hole wall is an outward-expanding conical hole wall. The second waterproof sealing ring 30 is located on the annular step wall. Usually, the outer annular surface of the second waterproof sealing ring 30 is adapted and positioned with the second inner hole wall, while the inner annular surface of the second waterproof sealing ring 30 is flush with the first inner hole wall or slightly exceeds the first inner hole wall toward the middle.Then, the tail buckle 205 is injection molded four times, and the tail buckle 205 is filled in the annular gap 4, and the tail buckle 205 extends integrally along the length direction of the second wire body 202 to wrap a small area, and the tail buckle 205 is exposed outside the second insulating outer mold 204, and plays a role in connecting the inner frame of the tail buckle 205, the second insulating outer mold 204 and the wire body. The structural design of the inner frame of the tail buckle 205 and the second insulating outer mold 204 takes into account the overall structural strength and the anti-breaking requirements at the outlet of the second wire body 202. Usually, the second insulating inner mold 203, the inner frame of the tail buckle 205, and the second insulating outer mold 204 are all made of harder plastic materials, which is conducive to maintaining the shape and size. The second insulating outer mold 204 has a good wrapping and protective effect. After the female data cable 200 and the male data cable 100 are plugged and adapted to each other, reliable positioning and sealing effects can be achieved.

[0044] The male connector 101 is inserted into the female connector 201, and the second insulating outer mold 204 is wrapped around the outer periphery of the first waterproof sealing ring 105, forming a sealed contact with more than two sealing convex rings 1051, playing a multiple sealing role. At the same time, the annular pressing end is pressed on the second waterproof sealing ring 30, thus forming double waterproofing.

[0045] like Figure 8 As shown, it shows a cross-sectional view of the female data cable 200 of the second embodiment; its structure is basically the same as that of the first embodiment, and the main difference is that the cross-section of the second waterproof sealing ring 30 of the second embodiment is L-shaped.

[0046] The second waterproof sealing ring 30 includes a radial portion 31 and an axial portion 32 that are integrally connected. The outer annular surface of the radial portion 31 is adapted to the second inner hole wall 2, and the axial portion 32 extends into the annular groove 4. The outer annular surface of the axial portion 32 is adapted to the first inner hole wall 1. For the second waterproof sealing ring 30 with an L-shaped cross-section, the annular groove can be used to better install and position the second waterproof sealing ring 30.

[0047] like Fig. 9 As shown, it shows a cross-sectional view of the male data cable 100 of the third embodiment; its structure is basically the same as that of the first embodiment, and the main difference is that the second waterproof sealing ring 30 of the third embodiment is sleeved on the plug-in section of the male connector 101.

[0048] like Fig.10As shown, it shows a cross-sectional view of the male data cable 100 of the fourth embodiment; its structure is basically the same as that of the first embodiment, with the main difference being that the second waterproof sealing ring 30 of the fourth embodiment is sleeved on the plug-in section of the male connector 101, and the cross-section of the second waterproof sealing ring 30 is L-shaped, specifically the second waterproof sealing ring 30 described in the second embodiment.

[0049] And, an electronic product is provided, which is applied with a double waterproof connecting line as described in any of the above items.

[0050] The design focus of the present invention is that it is easy to produce and manufacture mainly through the respective structural settings of the male data cable 100 and the female data cable 200. The male data cable 100 and the female data cable 200 are respectively compact integrated data cables. When in use, they are simply plugged in like traditional data cables, and double waterproofing is achieved after plugging in. Moreover, the male connector 101 and the female connector 201 are better protected and are not easily damaged.

[0051] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
