The projection of the outer surface 233-2 of the waterproof ring 230 on the xz plane is a ring shape, and the projection of the ring shape includes an inner edge and an outer edge, for example, if the projection of the ring shape is a circular ring, the radius of the inner edge of the circular ring can be referred to as the inner diameter of the circular ring, the radius of the outer edge of the circular ring can be referred to as the outer diameter of the circular ring, and the difference between the outer diameter and the inner diameter is the distance between the inner edge and the outer edge of the circular ring.
Illustratively, to facilitate sealing between the outer surface 233-2 of the waterproof ring 230 and the casing 101, a distance L2 may be spaced between the socket 101-1 and the inner edge 101-2A of the annular region 101-2.
Alternatively, the waterproof ring 230 may be a silicone ring. In other words, the material of the waterproof ring 230 is silicone. The material of the waterproof ring can also be ultraviolet curing UV glue (UV glue for short). In this embodiment, the material of the waterproof ring is not limited.
Referring to fig. 2, the tongue 240 is provided inside the inner case 210, and the tongue 240 penetrates the inner case 210, the outer case 220, and the waterproof ring 230 in a direction (i.e., y-direction) extending from one end of the outer case 210 to the other end.
In the present embodiment, the structure of the outer shell 220 may be various, and accordingly, the first structure formed by the waterproof ring 230 formed on the first surface 211 of the inner shell 210 and the first surface 221 of the outer shell 220 has different shapes, and for example, the specific structure of the waterproof ring 230, the inner shell 210, the outer shell 220, and the first structure formed by the waterproof ring 230 formed on the first surface 220 of the inner shell 210 and the first surface 221 of the outer shell 220 will be described in detail below.
Structure 1
In one possible implementation, the first surface 211 of the inner shell 210 and the first surface 221 of the outer shell 220 are in a first structure, the second surface 212 of the inner shell 210 and the second surface 222 of the outer shell 220 are connected (as shown in fig. 5C), the waterproof ring 230 includes a first inner surface 232-1, a second inner surface 232-2 and an outer surface 233-2 (as shown in fig. 6A and 6B), the first inner surface 232-1 and the second inner surface 232-2 of the waterproof ring 230 enclose a second structure, the second structure is matched with the first structure enclosed by the first surface 220 of the inner shell 210 and the first surface 221 of the outer shell 220 (as shown in fig. 3), and the first structure is a concave structure and the second structure is a convex structure.
Referring to fig. 5A and 5B, a first structure may be formed at an interface of the first surface 211 of the inner housing 210 and the first surface 221 of the outer housing 220 of the female connector 200, and with continued reference to fig. 5C, the first structure includes the first surface 211 of the inner housing 210 and the first surface 221 of the outer housing 220, and the first structure formed by the two interfaces may be referred to as a glue receiving groove for receiving the first inner surface 232-1 and the second inner surface 232-2 of the waterproof ring 230.
Thus, the first structure is formed on the first surface of the inner shell and the first surface of the outer shell of the female connector, and the waterproof ring is formed on the first structure through glue dispensing. The glue can be liquid silica gel, ultraviolet light polymerization glue or other materials capable of forming a waterproof ring. On one hand, compared with the formed waterproof ring which is directly assembled, the waterproof ring formed in a dispensing mode can be better attached to the inner shell and the outer shell of the female connector, glue overflow can be formed at the junction of the first surface of the inner shell and the first surface of the outer shell, and the possibility of water inflow of a gap between the inner shell and the outer shell is reduced; on the other hand, water can be through waterproof circle and inner shell, in the regional infiltration of shell contact goes into electronic equipment, form waterproof circle on first structure through the point is glued, can increase waterproof circle and inner shell, the area of contact of shell, in order to increase the distance that water flows through, for example, water need pass through the first surface of inner shell or the first surface of shell in proper order, just finally probably get into electronic equipment's inside, like this, the inside degree of difficulty of water infiltration electronic equipment has been increased in the intangible, thereby, electronic equipment's waterproof stability has been improved, electronic equipment's water-proof effects has been improved.
As a refinement of the present embodiment, the inner and outer shells 210 and 220 may be made of a metal material, such as iron. The inner and outer shells 210 and 220 may be formed by stamping, and then the inner and outer shells 210 and 220 may be assembled by spot welding.
In a conventional socket connector, in a process of forming the socket connector, an inner shell and an outer shell forming a glue receiving slot are integrated into a whole, and are formed by metal powder injection molding (i.e., MIM process technology), and the MIM process is generally used to realize fabrication of extremely complex geometric components. The specific process comprises the following steps: the injection molding raw material is prepared by mixing, heating, granulating and other processes by utilizing ultrafine metal powder and a binding agent, has fluidity, is molded into a green blank through a high-precision special mold (an injection molding machine), and is subjected to processes of dewaxing, sintering and the like to prepare the metal part with a complex shape. Thus, the cost of using this prior art is high.
The utility model provides a female seat connector makes inner shell, shell respectively through using comparatively simple technology (like the punching press), assembles it again (like spot welding), and the first surface of inner shell and the first surface of shell are connected and are formed first structure, form waterproof circle on this first structure through the point is glued for the surface of the waterproof circle that does not contact with the first surface of inner shell and the first surface of shell and electronic equipment's casing sealing fit, in order to realize end face seal. On one hand, the end face between the outer surface of the waterproof ring and the shell of the electronic equipment is sealed, and the first surface of the inner shell of the female connector and the gap between the first surface of the outer shell and the shell of the electronic equipment can be sealed to prevent water from permeating into the electronic equipment, so that the waterproof performance of the electronic equipment is improved; on the other hand, because the inner shell and the outer shell are manufactured respectively by using a simpler process and then assembled into a whole, the outer shell with the first structure is manufactured without adopting an MIM process technology with high cost and complex process, firstly, the cost caused by the process complexity of manufacturing the outer shell by the MIM process technology can be reduced, and secondly, compared with a structure for realizing radial sealing between the side surface of the waterproof ring and the shell of the electronic equipment, the end surface sealing is realized between the outer surface of the waterproof ring and the shell of the electronic equipment, the size of the female connector in the thickness direction can be reduced, so that the size of the electronic equipment in the thickness direction is reduced, and the size of the socket configured on the electronic equipment in the thickness direction is favorably reduced.
The waterproof ring 230 may have various shapes, which is not limited in the embodiment of the present application. Specifically, the embodiment of the present application does not limit the shape of the outer end surface 233-2 of the waterproof ring 230. For example, with continued reference to FIG. 6, the outer surface 233-2 of the waterproof ring 230 may be curved, alternatively, the outer surface 233-2 may also be planar.
Structure 2
In one possible implementation, as shown in fig. 7, the first surface 211 of the inner shell 210 and the first surface 221 of the outer shell 220 enclose a first structure, the second surface 212 of the inner shell 210 and the second surface 222 of the outer shell 220 are connected, the waterproof ring 230 includes a first inner surface 232-1, a second inner surface 232-2, and an outer surface 233-2 (as shown in fig. 8A and 8B), the first inner surface 232-1 and the second inner surface 232-2 of the waterproof ring 230 enclose a second structure, and the second structure matches the first structure enclosed by the first surface 220 of the inner shell 210 and the first surface 221 of the outer shell 220
Unlike the structure 1, the first surface 221 of the outer case 220 in the structure 2 is perpendicular to the first surface 211 of the inner case 210. Specifically, as shown in fig. 7A, the outer shell 220 may be formed by metal powder injection molding (i.e., MIM process technology) to form an MIM outer shell, and the inner shell 210 may be formed by stamping to form a metal inner shell. Compared with the inner shell and the outer shell which are both formed by the MIM process technology, the composite material still has the effect of lower cost. Alternatively, as shown in fig. 7B, for example, after the bent metal outer shell 220 is formed by stamping (e.g., 220 in fig. 5), the bent portion of the outer shell 220 is combined with the plastic outer shell 223, for example, the outer shell is placed in a mold that can be injection molded, so that the first surface 221 of the outer shell 220 is perpendicular to the first surface 211 of the inner shell 210, and the inner shell 210 can still be formed into a metal inner shell by stamping. Still alternatively, as shown in fig. 7C, for example, the outer shell 220 may be formed by stamping a metal material, so that the first surface 221 of the outer shell 220 is perpendicular to the first surface 211 of the inner shell 210, and the inner shell 210 may still be formed by stamping.
Therefore, the female seat connector of this application embodiment sets up the first surface into the first surface of perpendicular to inner shell through the first surface with the shell for after female seat connector and quick-witted shell terminal surface are sealed, the atress between the first internal surface of waterproof circle and the first surface of shell is more even, and the shell is more firm to the support of waterproof glue, thereby, can further improve electronic equipment's waterproof performance.
It should be noted that in other embodiments, the first surface 221 of the outer shell 220 and the first surface 211 of the inner shell 210 may be approximately perpendicular, or, not necessarily, perpendicular, and may form other angles (e.g., 110 °, 70 °). That is to say, as long as the inclination angle of the shell is matched with (for example, parallel to) the inclination angle of the chassis, the waterproof device can have the effects that after the female connector is sealed with the end face of the chassis, the stress between the first inner surface of the waterproof ring and the first surface of the shell is more uniform, and the shell supports the waterproof glue more stably.
It should be understood that the above structures 1 and 2 are only illustrative and should not be construed as limiting the embodiments of the present application, and any structure that can form the first structure at the interface of the first surface of the inner shell and the first surface of the outer shell is within the scope of the embodiments of the present application.
Further, in the first structure enclosed by the first surface of the inner case and the first surface of the outer case, if the molded rubber ring is directly sleeved on the first structure, a gap may be left between the first surface of the inner case and the first surface of the outer case, and this possible gap is also a way for water to penetrate into the electronic device, so in order to seal this possible gap, the embodiments of the present application further provide the following structure to further improve the sealing effect.
Specifically, the waterproof ring is formed on the first structure in a dispensing manner, and the waterproof ring can also be composed of a first part and a second part. Illustratively, the first portion 250 may be an adhesive layer and the second portion 260 may be a molded rubber ring. Fig. 9A is a schematic structural view of a partial area a of the female connector in the yz plane, wherein the partial area a can be understood as an area where the first structure formed by the inner shell and the outer shell and the waterproof ring are matched with each other by referring to the label of fig. 3.

The first portion 250 includes a first inner surface 232-1, a second inner surface 232-2, and a third inner surface 252-1, and the second portion 260 includes a fourth inner surface 264-1, a fifth inner surface 264-2, and an outer surface 233-2. The third inner surface 252-1 of the first portion 250 mates with the fourth inner surface 264-1 and the fifth inner surface 264-2 of the second portion, and the first inner surface 232-1 and the second inner surface 232-2 closely fit with the first structure formed by the first surface 211 of the inner casing 210 and the first surface of the outer casing 220.
In the process of manufacturing the female connector, the first portion 250 of the waterproof ring 230 may be formed by dispensing on the first surface 211 of the inner shell 210 and the first surface 221 of the outer shell 220, and then the molded second portion 260 may be pressed on the first portion 250.
Therefore, the first part of the waterproof ring is arranged between the second part of the waterproof ring and the first surface of the inner shell and between the second part of the waterproof ring and the first surface of the outer shell, the first part can be a viscous layer formed by dispensing, and a gap of a first structure formed by the first surface of the inner shell and the first surface of the outer shell in a surrounding mode can be effectively sealed, so that the waterproof effect of the electronic equipment is further improved. Furthermore, the first portion of the flashing ring may also improve the adhesion between the flashing ring and the first structure to better secure the flashing ring to the first structure.
Illustratively, the adhesive material of the waterproof ring first portion 250 may be an ultraviolet light curing (UV) glue. In the process of assembling the waterproof ring 230 on the first structure formed by the first surfaces 211 and 220 of the inner and outer housings 210 and 220 of the female connector, UV glue may be coated on the first surfaces 211 and 221 of the inner and outer housings 210 and 220, and the first portion 250 is formed by ultraviolet irradiation and curing, so as to closely adhere the first and second inner surfaces 232-1 and 232-2 of the waterproof ring 230 to the first structure formed by the first surfaces 211 and 220 of the inner and outer housings 210 and 220.
If the outer shell 220 is configured in the shape of the structure 2 (as shown in fig. 7A and 7B), i.e. the first surface 221 of the outer shell 220 is perpendicular to the first surface 211 of the inner shell 210, it can be referred to fig. 9B that the first portion 250 of the waterproof ring 230 is an adhesive layer and the second portion 260 is a molded rubber ring. The first portion 250 includes a first inner surface 232-1, a second inner surface 232-2, and a third inner surface 252-1, and the second portion 260 includes a fourth inner surface 264-1, a fifth inner surface 264-2, and an outer surface 233-2. The third inner surface 252-1 of the first portion 250 mates with the fourth inner surface 264-1 and the fifth inner surface 264-2 of the second portion, and the first inner surface 232-1 and the second inner surface 232-2 closely fit with the first structure formed by the first surface 211 of the inner casing 210 and the first surface of the outer casing 220.
In the process of manufacturing the female connector, the first portion 250 of the waterproof ring 230 may be formed by dispensing on the first surface 211 of the inner shell 210 and the first surface 221 of the outer shell 220, and then the molded second portion 260 may be pressed on the first portion 250.
Therefore, the first part of the waterproof ring is arranged between the second part of the waterproof ring and the first surface of the inner shell and between the second part of the waterproof ring and the first surface of the outer shell, the second part can be a viscous layer formed by dispensing, and a gap of a first structure formed by the first surface of the inner shell and the first surface of the outer shell in a surrounding mode can be effectively sealed, so that the waterproof effect of the electronic equipment is further improved. Furthermore, the first portion of the flashing ring may also improve the adhesion between the flashing ring and the first structure to better secure the flashing ring to the first structure.
Illustratively, the adhesive material of the waterproof ring first portion 250 may be an ultraviolet light curing (UV) glue. In the process of assembling the waterproof ring 230 on the first structure formed by the first surfaces 211 and 220 of the inner and outer housings 210 and 220 of the female connector, UV glue may be coated on the first surfaces 211 and 221 of the inner and outer housings 210 and 220, and the first portion 250 is formed by ultraviolet irradiation and curing, so as to closely adhere the first and second inner surfaces 232-1 and 232-2 of the waterproof ring 230 to the first structure formed by the first surfaces 211 and 220 of the inner and outer housings 210 and 220.
In the process of realizing data transmission or charging through the female connector, because the male connector is metal, if the inner shell and the outer shell of the female connector are also metal, electromagnetic waves may be generated by the metal of the male connector and the metal of the inner shell and the outer shell, and when the antenna is arranged at a position close to the female connector, the electromagnetic waves generated by the female connector may affect the performance of the antenna.
Therefore, the inner and outer shells 210 and 220 may be plastic inner and outer shells. In other words, the material of the inner and outer shells 210 and 220 is plastic.
Like this, through setting up inner shell, the shell with female connector into plastic inner shell, plastic shell, realizing data transmission or the in-process that charges through female connector, can avoid metallic shell and public head to produce the electromagnetic wave to reduce the influence to the antenna performance, improve electronic equipment's antenna performance.
