Description

Technical Field

[0001] The utility model relates to a structure of an electric connector shielding shell with improved stabilization effect. Background Art

[0002] The most commonly used electrical connector interfaces at present are Universal Serial Bus (USB for short), which is smaller in size and easier to carry and is widely used in various consumer electronic products and corresponding transmission lines for docking with them. Among them, the interface size of the USB Type-C electrical connector is smaller than the interface size of the current USB-A specification, so the terminals and cable diameters used by the Type-C electrical connector are also smaller and thinner than those of other specifications of USB connectors.

[0003] However, the above USB Type-C electrical connector does have the following problems and deficiencies when in use and needs to be improved:

[0004] The USB Type-C electrical connector is a relatively thin structure, so when it is set in a vertical position, it will be more prone to bending and deformation, which will cause the setting angle to shift and make it impossible to use normally. In particular, when the user uses abnormal means to shake it for a long time to plug and unplug it, it is more likely to cause the USB Type-C electrical connector to open.

[0005] Therefore, how to solve the above-mentioned conventional problems and deficiencies is the direction that the applicant of the utility model and related manufacturers engaged in this industry are eager to study and improve. Utility Model Content

[0006] The main purpose of the present invention is to provide a structure of an electrical connector shielding shell which can prevent the electrical connector from tilting, shaking and other problems by means of a reinforcement portion formed by extending the shielding shell. Specifically, by utilizing the design of the balancing portion, when the shielding shell shakes due to abnormal plugging and unplugging actions, the shielding shell can be effectively balanced and supported to minimize the degree of shaking. At the same time, by using the technology of inserting and fixing the positioning portion downward, the shielding shell can not only reduce the degree of shaking to a minimum, but can even be almost completely fixed and unable to shake. It can be seen that the reinforcement portion is particularly important for the fixing effect of the present invention.

[0007] In order to achieve the above main purpose, the utility model provides a structure of an electrical connector shielding shell, which is characterized by comprising:

DETAILED DESCRIPTION

[0038] See also Figures 1 to 4 As shown, it is a three-dimensional diagram of the first preferred embodiment of the utility model. Figure 1 As for the insertion side perspective view, it can be clearly seen from the figure that the utility model includes:

[0039] A transmission conductor set 1 conforming to the USB TYPE-C communication protocol, comprising a contact portion set 11, a base portion set 12 extending downward from the contact portion set 11, and a welding portion set 13 extending from one end of the base portion set 12 away from the contact portion set 11;

[0040] An insulating colloid 2 covering the transmission conductor set 1 has a tongue plate 21 for setting the contact portion set 11 and a fixing base 22 for fixing the base portion set 12, and the contact portion set 11 and the welding portion set 13 are exposed to the outside;

[0041] A shielding shell 3 covering the insulating colloid 2 and accommodating the insulating colloid 2, having a front end portion 31 for surrounding the tongue plate 21, and a middle end portion 32 for covering the fixing base 22 for fixing, the middle end portion 32 having two first side edges 321 and two second side edges 322 located on different sides of the first side edges 321 and having a lateral length shorter than the first side edges 321, and one of the first side edges 321 extending away from the front end portion 31 to form at least one fixing portion 323;

[0042] A reinforcing portion 324 is extended to form each of the second side edges 322, and the reinforcing portion 324 has a connecting portion 3241 connected to the middle end portion 32, a balancing portion 3242 extended from the end of the connecting portion 3241 away from the middle end portion 32 to the two side edges, and a plurality of positioning portions 3243 extended downwardly from both ends of the balancing portion 3242, and each of the positioning portions 3243 is respectively located at the outer side of the second side edge 322 of the middle end portion 32 in the length direction.

[0043] The transmission conductor group 1 is a terminal group.

[0044] The welding part group 13 is arranged in a single row. The single row arrangement can effectively shorten the welding time and simplify the process when the electrical connector of the utility model is connected to the circuit substrate 4, thereby increasing the manufacturing speed and reducing the cost.

[0045] The soldering portion assembly 13 is formed by bending to be combined with the circuit substrate 4 by surface-mount technology (SMT).

[0046] The insulating colloid 2 is integrally formed.

[0047] The base assembly 12 is embedded in the fixing base 22 to form a fixed shape.

[0048] The shielding shell 3 is integrally formed by stamping.

[0049] The connecting portion 3241 is formed by the second side edge 322 extending vertically downward directly, and then horizontally extending to the left and right sides to form the balancing portion 3242 , and finally vertically extending downward from the left and right ends of the balancing portion 3242 to form the positioning portion 3243 .

[0050] The positioning portions 3243 are located at the outer sides of the second side edges 322 of the middle end portion 32 in the length direction. Figure 4 It can be seen that the two edges of the middle end portion 32 located on the second side 322 define a second side imaginary line A, and the outer edges of the two positioning portions 3243 define a positioning portion imaginary line B. It can be clearly seen that the positioning portions 3243 are arranged on the two outer sides of the middle end portion 32. Through this technical feature, the electrical connector can be effectively stabilized so that it is not easy to shake or tilt and deform.

[0051] When the opponent electrical connector and the electrical connector of the present invention are plugged into each other, the contact portion group 11 of the transmission conductor group 1 can be differentially connected to the opponent electrical connector. At this time, the electrical signal will be transmitted to the circuit substrate 4 through the base group 12 and the welding portion group 13 in sequence to form electrical conduction. The transmission conductor group 1 complies with the USB TYPE-C communication protocol, so the electrical connector of the present invention is faster than the general USB TYPE-A electrical connector in transmission speed, transmits more power, and is smaller in size. For this reason, the reinforcement portion 324 must be used to prevent the user from using an incorrect plugging and unplugging posture to cause damage to the electrical connector.

[0052] Even though the transmission conductor assembly 1 has a certain stability effect through the tongue plate 21 of the insulating colloid 2 and the fixing base 22, the overall stability of the electrical connector, especially the lateral force during plugging and unplugging, still needs to rely on the reinforcement portion 324 to enhance the stability.

[0053] In other words, Figure 4 When the lateral force is generated, since the positioning portion 3243 is inserted into the circuit substrate 4 and the lower side of the balancing portion 3242 is against the upper surface of the circuit substrate 4, the lateral force will be supported by the balancing portion 3242, effectively preventing the shielding shell from tilting. In particular, each of the positioning portions 3243 is respectively located on the outer side of the second side edge 322 of the middle end portion 32 in the length direction, thereby forming an effect of a wider supporting fulcrum, which increases the supporting area like a crane.

[0054] Furthermore, the fixing portion 323 not only increases the grounding channel, but also helps to assist the supporting effect of the shielding shell 3, especially in terms of the supporting force of the first side 321, which has the advantage of enhancing stability.

[0055] See also Figure 5 As shown, it is a schematic diagram of the implementation of the second preferred embodiment of the utility model. It can be clearly seen from the figure that the difference between this embodiment and the aforementioned embodiment lies in that each positioning portion 3243 of this embodiment is respectively provided with a perforated portion 3244. Through the design of the perforated portion 3244, the solder can be contained inside, which effectively improves the bonding force between the solder and the positioning portion 3243 and enhances the fixing effect of the positioning portion 3243.

[0056] See also Figure 6 and Figure 7As shown, it is a combined three-dimensional schematic diagram and an exploded diagram of the third preferred embodiment of the utility model. It can be clearly seen from the figure that the difference between this embodiment and the aforementioned first preferred embodiment is that the middle end portion 32 of this embodiment is located at each second side 322 and is respectively provided with a latch portion 325, and the fixed base 22 is provided with a plurality of docking portions 222 that are latched and fixed with the latch portion 325, and a coupling portion 223 that can be mutually coupled with the first side 321, wherein the latch portion 325 in this embodiment is an example of a spring clip buckle, the docking portion 222 in this embodiment is an example of a groove, and the coupling portion 223 in this embodiment is an example of a flange. Accordingly, when the shielding shell 3 is combined with the insulating colloid 2, the elastic characteristics of the latch portion 325 can be docked and engaged with the docking portion 222, so that the insulating colloid 2 will not fall off downward, and the coupling portion 223 can contact the edge of the first side 321, so that the insulating colloid 2 will not fall off upward, and the coupling force between the insulating colloid 2 and the shielding shell 3 is effectively stabilized.

[0057] See also Figure 8 and Fig. 9 The figure is a three-dimensional perspective view of the fourth preferred embodiment of the utility model. Figure 1 and Stereoscopic Perspective Figure 2 As can be clearly seen from the figure, the difference between this embodiment and the aforementioned first preferred embodiment is that the fixed base 22 of this embodiment is provided with a plurality of limiting portions 221 at the side close to the front end portion 31, and the front end portion 31 is provided with a joint portion 311 which can be correspondingly combined with each limiting portion 221, wherein the limiting portion 221 in this embodiment is a groove as an example, and the joint portion 311 in this embodiment is a convex portion as an example. Accordingly, when the shielding shell 3 is combined with the insulating colloid 2, it can be accommodated in the limiting portion 221 through the joint portion 311, resulting in the limitation in the left and right direction (the length direction of the first side 321) and the rear direction (the direction of the contact portion group 11 toward the welding portion group 13), effectively enhancing the combination and fixing effect of the insulating colloid 2 and the shielding shell 3.

[0058] See also Fig.10 As shown, it is a schematic diagram of the implementation of the fifth preferred embodiment of the utility model. It can be clearly seen from the figure that the difference between this embodiment and the aforementioned first preferred embodiment is that a fixing through hole 3231 is provided on the fixing portion 323 of this embodiment. Through the design of the fixing through hole 3231, solder can be contained inside, which effectively improves the bonding force between the solder and the fixing portion 323 and enhances the fixing effect of the fixing portion 323.

[0059] See also Fig.11As shown in the figure, it is a stereoscopic view of the sixth preferred embodiment of the utility model. It can be clearly seen from the figure that the difference between this embodiment and the aforementioned first preferred embodiment is that a gradually expanding guide portion 312, also known as a bell mouth, is provided on the front end portion 31 of the present embodiment, so that when the hand electric connector is plugged in, it can pass through the gradually expanding guide portion 312. Even if the plug-in position is slightly deviated, it can also be guided by the guide portion 312 to enter the front end portion 31 and dock with the contact portion group, thereby achieving the advantage of quick plug-in without the need for precise alignment.

[0060] See also Fig.12 As shown, it is a stereoscopic view of the seventh preferred embodiment of the utility model. It can be clearly seen from the figure that the difference between this embodiment and the aforementioned first preferred embodiment is that a plurality of reinforcing ribs 33 are provided on the shielding shell 3 of this embodiment. Through the design of each reinforcing rib 33, the strength of the shielding shell 3 can be effectively enhanced to prevent the shielding shell 3 from being deformed due to the backward force generated by the plugging process of the opponent electrical connector. In other words, when the opponent electrical connector is inserted into the electrical connector, if it hits the front end 31 of the shielding shell 3 for a long time, deformation is likely to occur between the front end 31 and the middle end 32 to form a convex state. Therefore, through the design of the reinforcing ribs 33, the structural strength of the shielding shell 3 can be enhanced.

[0061] See also Fig.13 , which is a schematic diagram of the enhanced grounding of the eighth preferred embodiment of the utility model. The difference between this embodiment and the aforementioned first preferred embodiment is that the balancing portion 3242 of this embodiment extends between each positioning portion 3243 to form a grounding portion 3245, wherein the grounding portion 3245 in this embodiment is a convex piece as an example, and is integrally formed with the reinforcement portion 324. Accordingly, through the design of the grounding portion 3245, the grounding venting channel can be effectively increased, thereby improving the advantage of suppressing noise interference.

[0062] See also Fig.14 and Fig.15As shown, it is a three-dimensional view and an exploded view of the ninth preferred embodiment of the utility model. It can be clearly seen from the figure that the difference between this embodiment and the aforementioned first preferred embodiment is that this embodiment is further provided with a perforated portion 3244 on the positioning portion 3243, a latch portion 325 is provided at each second side 322 of the middle end portion 32, a plurality of docking portions 222 that are latched and fixed with the latch portion 325 and a combining portion 223 that can be combined with the first side 321 are provided on the fixed base 22, a plurality of limiting portions 221 are provided on the side of the fixed base 22 close to the front end portion 31, and a correspondingly combined with each limiting portion 22 is provided on the front end portion 31. 1, a fixing through hole 3231 is provided on the fixing portion 323, a gradually expanding guide portion 312 is provided on the front end portion 31, and a plurality of reinforcing ribs 33 are provided on the shielding shell 3. That is, the utility model can combine the above-mentioned through hole 3244, the latch portion 325, the docking portion 222, the connecting portion 223, the limiting portion 221, the connecting portion 311, the fixing through hole 3231, the guide portion 312, and the reinforcing ribs 33 and other technical features on the electrical connector of the utility model, so that the electrical connector of the utility model can have the advantages achieved by the above structure at the same time. The advantages of the above structure have been set forth in the above-mentioned embodiment, so they are not repeated here.

[0063] Therefore, the structure of the shielding shell of the electrical connector of the present invention is to improve the conventional technology.

[0064] First, the design of the reinforcing portion 324 formed by extending the shielding shell 3 can prevent the electrical connector from being skewed or shaken when being plugged in or out.

[0065] Secondly, the design of the balancing portion 3242 can effectively balance and support the shielding shell 3 when the shielding shell 3 is shaken due to an abnormal plugging and unplugging action, so as to minimize the degree of shaking.

[0066] Thirdly, by using the technology of inserting and fixing the positioning portion 3243 downward, the shielding shell 3 can not only reduce the shaking degree to the minimum, but also be almost completely fixed and unable to shake.

[0067] Fourthly, through the design of the through-hole portion 3244 , the solder can be contained therein, thereby effectively improving the bonding force between the solder and the positioning portion 3243 , and enhancing the fixing effect of the positioning portion 3243 .

[0068] Fifth, the elastic characteristics of the latch portion 325 engage with the docking portion 222 to prevent the insulating colloid 2 from detaching downward, and the coupling portion 223 abuts against the edge of the first side 321 to prevent the insulating colloid 2 from detaching upward, thereby effectively consolidating the coupling force between the insulating colloid 2 and the shielding shell 3.

[0069] Sixth, by accommodating the joint portion 311 in the limiting portion 221 , limiting in the left-right direction and the rear direction is generated, thereby effectively strengthening the combination and fixing effect of the insulating colloid 2 and the shielding shell 3 .

[0070] Seventh, through the design of the fixing through hole 3231 , the solder can be contained therein, thereby effectively improving the bonding force between the solder and the fixing portion 323 , and enhancing the fixing effect of the fixing portion 323 .
