Detailed Description

In order to make the objects, technical solutions and advantages of the present application more clear, the present application will be further described in detail with reference to the accompanying drawings.

At present, wearable electronic equipment such as intelligent wrist-watch, intelligent bracelet combines together the function of latest IT technique and traditional equipment to have advantages such as portable, easy to use, function abundance, consequently receive liking of vast consumers deeply. Some conventional wearable electronic devices are large in size, inconvenient to carry, and affect wearing aesthetics.

Referring to fig. 1, taking a smart band as an example, the smart band generally includes a dial and a band. Wherein the span L of the surface plate along the wearing direction is usually between 46 and 50 mm. This span size's intelligent bracelet only is suitable for the user that the wrist is thicker to wear, and the user that the wrist is thin can seriously influence it when wearing and wear the aesthetic property to can influence the experience of wearing of the thin user of this wrist.

At present, electronic equipment 0 adopts the Type C interface as its interface and the signal transmission interface that charge more, and is no exception in wearing equipment such as intelligent wrist-watch, intelligent bracelet. However, when the conventional standardized Type C interface is set, the size of the electronic device 0 cannot be reduced by the limitation of the stacking space of the electronic device 0 as a whole, so that the size of the electronic device 0 as a whole cannot be reduced. In order to solve the above problem, the present application provides a female connector holder 1, and the female connector holder 1 can be disposed on the electronic device 0 to serve as a charging interface and a signal transmission interface of the electronic device. In order to understand the female connector housing 1 provided in the embodiments of the present application, the following detailed description is provided with reference to the accompanying drawings.

Referring to fig. 2, an embodiment of the present application provides a female connector holder 1, where the female connector holder 1 includes a housing 101, a tongue piece 102, and a welding plate 103, the tongue piece 102 is inserted into a cavity of the housing 101, and the welding plate 103 is used for connecting with the housing 101 to fix the tongue piece 102 with the housing 101.

When the tongue 102 is specifically provided, the tongue 102 includes a plurality of terminals 1021, and the plurality of terminals 1021 have contact portions 10211 and soldering portions 10212. Among them, the contact portion 10211 is used for contacting with a terminal of the male connector for signal transmission between the female connector holder 1 and the male connector. The soldering portion 10212 of the tongue piece 102 is used for connecting with a corresponding pin pad on the circuit board 2 (flexible circuit board 2 or printed circuit board 2) of the electronic device 0, so as to realize signal transmission between the connector female housing 1 and the circuit board 2. In order to achieve stable connection of the soldering portions 10212 of the respective terminals 1021 and the pin pads, referring to fig. 2, the soldering portions 10212 of the respective terminals 1021 are arranged side by side at intervals, and end surfaces of the respective soldering portions 10212 for contacting the pin pads are flush.

In the embodiment of the present application, the number of the terminals 1021 in the tongue piece 102 is not specifically limited, and may be set according to the function to be realized by the female connector holder 1. Referring to fig. 4, for example, in one possible embodiment of the present application, the tongue piece 102 may have 12 terminals, and referring to fig. 5, the contact portions 10211 of the 12 terminals may be arranged in two rows, and the soldering portions 10212 of the terminals 1021 may be arranged in one row, so as to simplify the structure of the tongue piece 102. In addition, with continued reference to fig. 5, in some embodiments of the present application, the solder portion 10212 is formed by bending one end of the terminal 1021. In the embodiment of the present application, the contact portion 10211 and the soldering portion 10212 are connected by the connection portion 10213, and the connection portion 10213 is a one-time bending structure, so as to effectively simplify the structure of the terminal 1021.

The connection portion 10213 is a structure in which a portion of the terminal other than the contact portion 10211 and the soldering portion 10212 is bent at one time.

It is understood that, when the female connector holder 1 according to the embodiment of the present invention is connected to the male connector, the number of the terminals 1021 in the female connector holder 1 according to the embodiment of the present invention is generally the same as the number of the terminals in the male connector. In some embodiments of the present application, in conjunction with fig. 2 and 3, some terminals 1021 corresponding to the unusual functions may be omitted to simplify the structure of the tongue 102. In this way, the number of the soldering portions 10212 of the tongue piece 102 arranged side by side can be reduced to facilitate the reduction of the width of the tongue piece 102 (the length of the soldering portions 10212 in the arrangement direction), thereby providing a possibility for the miniaturization design of the female connector housing 1.

The female connector holder 1 has a contact area 11 (see fig. 9) to be brought into contact with the male connector, and the contact portion 10211 of the terminal 1021 of the tongue piece 102 is located in the contact area 11. When the number of the terminals 1021 in the embodiment of the present invention is adjusted, the width of the contact region 11 of the tongue piece 102 can be prevented from being changed, so that the female connector holder 1 in the embodiment of the present invention can be fitted to a large number of standardized male connectors, and the application range of the female connector holder 1 in the embodiment of the present invention is widened.

When the number of the terminals 1021 of the female connector holder 1 of the embodiment of the present application is less than the number of the terminals 1021 of the male connector, referring to fig. 3, the distribution manner of the terminals 1021 on the tongue 102 may be the same as the distribution manner of the terminals 1021 in the male connector for achieving the same function, so that when the male connector is plugged into the female connector holder 1, the terminals at the corresponding positions can be effectively contacted, thereby achieving effective transmission of signals. Since the plurality of terminals of the female connector holder 1 include signal terminals, power terminals and ground terminals, in other embodiments of the present invention, an insulating material may be used to form a barrier 1022 between the power terminals 1021 and the ground terminals 1021, and the barrier 1022 may be, but is not limited to, disposed at the position of the omitted terminals 1021 (e.g., signal transmission terminals). Thus, when the female connector holder 1 is fed with liquid, the risk of short-circuiting the adjacent two terminals 1021 can be reduced. In addition, the number of the blocking parts 1022 may be adjusted according to the arrangement of the terminals 1021, and may be 1, 2, 3 or more.

With continued reference to fig. 3, the tongue 102 is further provided with a first limiting structure 1023, and the first limiting structure 1023 can be used for fixing and limiting a plurality of terminals 1021 of the tongue 102. The first position limiting structure 1023 can be made of plastic insulating material such as plastic. In some embodiments of the present invention, the barrier 1022 may be, but is not limited to, manufactured in a single process with the first limiting structure 1023, which is beneficial to simplify the manufacturing process of the tongue piece 102 and provide the tongue piece 102 with better structural stability.

With reference to fig. 2, when the housing 101 is specifically provided, the housing 101 has a stopping portion 1011, and during the process of installing the tongue piece 102 into the cavity of the housing 101, the stopping portion 1011 acts as a limit for the tongue piece 102, so as to prevent the tongue piece 102 from moving in the direction of installing the tongue piece 102 into the housing 101, thereby improving the structural stability of the female connector housing 1 according to the embodiment of the present application.

In addition, the housing 101 is provided with an escape opening 1012, and the escape opening 1012 opens in the direction opposite to the direction in which the tongue piece 102 is fitted into the housing 101. When the tongue piece 102 is mounted in the case 101, the escape opening 1012 acts to escape the soldering portion 10212 of the terminal 1021 of the tongue piece 102, and thus interference of the case 101 with the soldering portion 10212 can be avoided. In this embodiment, by avoiding the welded portion 10212 through the avoiding port 1012, part or all of the welded portion 10212 can be overlapped with the housing 101, which is advantageous for reducing the length of the assembly of the tongue piece 102 and the housing 101 (the dimension in the direction in which the tongue piece 102 is fitted into the housing 101), thereby being advantageous for realizing the miniaturized design of the female connector housing 1 according to the embodiment of the present application.

With reference to fig. 2, the first positioning pin 1013 is further disposed on the surface of the housing 101, the first positioning pin 1013 is disposed within the contour of the bottom surface of the housing 101 (the bottom surface of the housing 101 is the surface of the housing 101 facing the circuit board when the housing 101 is mounted on the circuit board), and the first positioning pin 1013 and the soldering portion 10212 of the tongue piece 102 are disposed on the same side of the female connector holder 1, so as to avoid the additional increase of the length or width dimension of the female connector holder 1 due to the first positioning pin 1013, which is beneficial to the miniaturization of the female connector holder 1. In addition, to perform the limiting function, the number of the first positioning pins 1013 may be two or more, and exemplarily, the number of the first positioning pins 1013 is three, four, or six, and the like. Referring to fig. 6, taking four first positioning pins 1013 as an example, when the female connector housing 1 according to the embodiment of the present application is installed on the circuit board 2, the circuit board 2 is provided with positioning holes 201, and the first positioning pins 1013 can be inserted into the positioning holes 201 on the circuit board 2 in a one-to-one correspondence manner, so as to define the relative position between the female connector housing 1 and the circuit board 2, thereby being beneficial to improving the connection accuracy between the soldering portion 10212 of the tongue piece 102 and the corresponding pin pad on the circuit board 2, further improving the contact stability thereof, and enabling the first positioning pins 1013 to protect the terminal 1021. In addition, the first positioning pins 1013 can be soldered to the circuit board 2 by filling solder into the positioning holes 201, so as to realize the fixed connection between the connector base 1 and the circuit board 2. It will be appreciated that the flexible circuit board is designed to be smaller in thickness and more flexible in its placement in an electronic device due to its bendable nature. Therefore, in the embodiment of the present application, the circuit board 2 may be selected as a flexible circuit board to facilitate a miniaturized design of the electronic apparatus.

In some embodiments of the present application, referring to fig. 7A and 7B, a support pin 1014 may be further disposed on the housing 101, and the support pin 1014 and the first positioning pin 1013 are disposed on the same side surface of the housing 101. In particular arrangements of the support pins 1014, as can be seen in fig. 7A, the support pins 1014 can be separate structures disposed on the surface of the housing 101. In other embodiments, referring to fig. 7B, a step may be further disposed between the first positioning pin 1013 and the housing 101 as the supporting pin 1014, and in this embodiment, the supporting pin 1014 and the first positioning pin 1013 may be an injection-molded integral structure. Alternatively, a washer can be placed over the first retention pin 1013 to serve as the support pin 1014. Referring to fig. 8, support pins 1014 are raised above the surface of housing 101 by the same height as solder 10212 of tab 102 is raised above the surface of housing 101. When the female connector holder 1 according to the embodiment of the present application is mounted on the circuit board 2, the support pins 1014 and the soldering portions 10212 jointly support the female connector holder 1, so as to prevent the female connector holder 1 from tilting, and to improve the connection reliability between the female connector holder 1 and the circuit board 2.

With continued reference to fig. 2, after the tongue piece 102 is attached to the case 101, the tongue piece 102 may be prevented from falling out of the case 101 by fixing the welding plate 103 to the case 101. When the weld plate 103 is specifically configured, a notch 1031 is formed in the weld plate 103, and the notch 1031 can act as a relief for the weld portion 10212 of the tab 102.

In addition, referring to fig. 2, in the process of mounting the welding plate 103 on the housing 101, in order to position the welding plate 103 and the housing 101, a first positioning structure 1015 may be further disposed on the housing 101, and a second positioning structure 1032 may be further disposed on the welding plate 103, so that the welding plate 103 and the housing 101 are positioned by the matching connection of the first positioning structure 1015 and the second positioning structure 1032. When the first positioning structure 1015 and the second positioning structure 1032 are specifically arranged, for example, the first positioning structure 1015 may be a positioning column arranged on the surface of the housing 101, and the second positioning structure 1032 may be a positioning hole opened on the welding plate 103; alternatively, the first positioning structure 1015 is a positioning hole opened on the welding plate 103, and the second positioning structure 1032 is a positioning column disposed on the surface of the housing 101. Thus, the positioning of the welding plate 103 and the housing 101 can be conveniently realized by matching and inserting the positioning holes and the positioning columns.

In some embodiments of the present application, when the welding board 103 is connected to the housing 101, the welding point 1033 may be formed on the welding board 103 by laser spot welding, so that the welding board 103 is welded to the housing 101 by the welding point. In addition, when the second positioning structure 1032 on the soldering board 103 is a positioning hole, it can be understood that the positioning hole is filled with solder to realize the fixed connection between the soldering board 103 and the housing 101.

In other embodiments of the present application, referring to fig. 2, a protrusion 1024 may be further disposed on a surface of the tongue 102 facing the welding plate 103, and the protrusion 1024 is made of an insulating material having plasticity, such as plastic. In addition, the protrusions 1024 may be, but not limited to, dot-shaped protrusions, rib-shaped protrusions, annular protrusions, or the like. When the projection 1024 is rib-shaped, the extending direction of the projection 1024 may be, but not limited to, a direction perpendicular or parallel to the soldering surface of the terminal 1021. In one possible implementation, the protrusion 1024 may be formed in a single process with the barrier 1022 and the first stop 1023 of the tongue 102, which is advantageous for simplifying the structure of the tongue 102 and improving the structural stability of the tongue 102. In some embodiments of the present disclosure, the height of the protrusion 1024 above the setting surface may be, but not limited to, 0.01mm, 0.02mm, or 0.03mm, and the like, so that, after the tongue 102 is installed in the housing 101, the welding plate 103 presses the protrusion 1024 during the process of fixing the tongue 102 by the welding plate 103, so as to compensate for the gap between the welding plate 103 and the tongue 102 through the deformation of the protrusion 1024, and thus press the tongue 102 to the housing 101, so as to prevent the tongue 102 from shaking in the housing 101, and thus the connector female socket 1 of the embodiments of the present disclosure has better structural stability. In addition, interference between the tongue piece 102 and the welding plate 103 is achieved by providing the tongue piece 102 with a deformable protrusion 1024, which is also beneficial to avoid a large gap between the welding plate 103 and the housing 101.

By performing USB bending simulation on the terminal 1021 of the tongue piece 102 of the female connector holder 1 and the first positioning pin 1013 of the housing 101, it can be known that the maximum principal stress of the terminal 1021 and the first positioning pin 1013 of the female connector holder 1 of the embodiment of the present application is 121.34Mpa, which is smaller than the simulation baseline 200Mpa, and therefore the failure risk is low.

Referring to fig. 9, fig. 9 is a plan view of the female connector housing 1 according to an embodiment of the present application. In one possible embodiment of the present application, the female connector housing 1 further has a welding area 12, and the welding portion 10212 of the terminal is disposed on the welding area 12. Where the length L1 of the contact region 11 of the female connector holder 1 is 4.05mm and the length L2 of the land 12 is 1.05mm, the total length L1+ L2 of the female connector holder 1 of this embodiment is 4.05mm +1.05mm or 5.1 mm.

In this embodiment, the first positioning pins 1013 on the housing 101 of the female connector holder 1 fall within the range of the contact region 11, and in addition, referring to fig. 10, the number of the terminals 1021 in the tongue piece 102 of the female connector holder 1 may be set to 12. Wherein the width of contact zone 11 is D1; the width of the wall thickness regions 13 of the housing 101 on both sides of the contact region 11 in the width direction is D2, and the width D of the female connector holder 1 of this embodiment is D1+2 × D2.

To further illustrate the current capacity of the female connector housing 1 of the present application, it is compared to a conventional female connector housing 1'.

In addition, in the width direction, referring to fig. 10 and 13 together, the width D of the female connector holder 1 of the embodiment of the present application is the sum of the width D1 of the contact region 11 and the width D2 of the wall thickness region 13 of the housing 101 on both sides of the contact region 11, whereas the width D 'of the conventional female connector holder 1' is the sum of the width D1 'of the contact region 11', the width D2 'of the two pin regions 14', and the width D3 'of the two second lands 15' respectively formed by the second positioning pins 1013 'flaring toward the housing 101'. First, in order to make the female connector holder 1 of the embodiment of the present application adaptable to most standardized male connectors, the width D1 of the contact area 11 of the female connector holder 1 of the embodiment of the present application is equal to the width D1 ' of the contact area 11 ' of the conventional female connector holder 1 '. Secondly, the width D2 of the wall thickness region 13 of the housing 101 of the connector female socket 1 of the embodiment of the present application on both sides of the contact region 11 is mainly determined by the wall thickness of the housing, which is much smaller than the sum of the width D2 ' of the two pin regions 14 ' and the width D3 ' of the two second welding regions 15 ' of the conventional connector female socket 1 ' (which includes the wall thickness of the housing). Finally, the number (12) of the terminals 1021 is smaller than the number (18) of the terminals 1021 'of the conventional female connector housing 1', and the width of the soldering portions 10212 of the terminals 1021 arranged side by side does not affect the overall width of the female connector housing 1; in addition, in the embodiment of the present application, the first positioning pin 1013 is disposed to overlap the contact region 11, which does not affect the overall width of the contact socket 1. Therefore, the width D of the connector female housing 1 of the embodiment of the present application can be designed smaller as compared with the width D 'of the conventional connector female housing 1'.
