Abstract
Description
Technical Field
[0001] This utility model relates to the field of connectors, and more specifically to an improved male connector. Background Technology
[0002] A shielding spring, also known as an EMI shielding spring, is installed on the outside of the insulating body of the Type-C connector. Its function is to form an electromagnetic shielding layer, which isolates the internal circuit from the external environment, effectively reduces the leakage of electromagnetic radiation generated by the Type-C interface and its connection lines, reduces interference to other electronic devices in the vicinity, prevents the impact on wireless communication, broadcasting and television signals, and enables the equipment to comply with relevant electromagnetic compatibility standards.
[0003] Existing shielding springs typically have shielding portions covering the top and bottom of the insulating body, and pins for insertion into both sides of the insulating body. A bend is formed between the shielding portion and the pins. Whether the shielding spring is fixed to the insulating body by interference fit or by clamping it to both sides of the insulating body with the pins, the interference fit between the metal shielding spring and the insulating body can easily damage the soft plastic, leading to failure of the snap-fit. This affects the product's functionality, production cost, and production efficiency. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides an improved male connector, comprising a metal shell and an insulating body enclosed by the metal shell. A terminal assembly is installed within the insulating body, and a receiving cavity is provided within the insulating body. A connection port is formed on one side of the receiving cavity. Shielding plates are respectively provided at the top and bottom of the receiving cavity. Each shielding plate includes a shielding portion, which is respectively disposed at the top and bottom of the receiving cavity. Clamping arms extend from both sides of the shielding portion near the connection port along the sidewall between the top and bottom of the receiving cavity, respectively. A bent portion is formed between the clamping arms and the shielding portion. The clamping arms are interlocked and form a snap-fit fixation in a direction parallel to the sidewall of the receiving cavity.
[0005] Furthermore, when the latching arms intersect each other on the sidewalls of the receiving cavity, the ends of the latching arms away from the bending portion bend outwards to form latching portions, and the latching portions are fixed together by a latch.
[0006] Furthermore, an inclined surface is provided at the end of the latching part, and the inclined surfaces are parallel to each other.
[0007] Furthermore, a groove is provided on the side of the latching arm away from the latching part.
[0008] Furthermore, a protrusion is provided on the end face of the latching arm facing outward, and an abutment is provided on the insulating body opposite to the protrusion. When the latching arm moves towards each other along the side wall of the receiving cavity, the abutment presses against the protrusion, so that the latching arm can squeeze the two sides of the receiving cavity. There is a first redundant space between the latching parts.
[0009] Furthermore, the terminal assembly includes an upper terminal group and a lower terminal group, each of which includes a resilient connecting portion, a main body portion, and a welding portion arranged sequentially, with the resilient connecting portion disposed within a receiving cavity.
[0010] Furthermore, a plurality of receiving grooves are provided at the top and bottom of the receiving cavity, the receiving grooves extending vertically through the top and bottom of the receiving cavity, the number of receiving grooves being the same as the number of terminals in the upper terminal group and the lower terminal group, and the positions of the receiving grooves corresponding vertically to the elastic connecting part.
[0011] Furthermore, a plurality of first elastic portions are provided on the side of the shield near the connection port, and the first elastic portions bend toward the receiving cavity.
[0012] Furthermore, a through groove is provided on one side of the first elastic part, and an insulating shielding plate is covered on the through groove. The insulating shielding plate covers the outside of the receiving groove. Second elastic parts are provided at both ends of the insulating shielding plate. The second elastic parts bend outward toward the receiving cavity, and the second elastic parts then form a second redundant space between the metal shell and the insulating body.
[0013] Furthermore, the insulating shielding plate includes a covering end, a slot is provided at one end of the covering end, a first inclined portion is provided at the top of the slot, an insert plate is provided inside the through slot, and a second inclined portion is provided at the top of the insert plate. When the insulating shielding plate covers the through slot, the insert plate is inserted into the slot, and the first and second inclined portions are in contact. The thickness of the covering end is between 0.08 and 0.12 mm.
[0014] Compared with the prior art, the beneficial effects of the present invention are:
[0015] The bending portion described in this application does not need to be elastic. Therefore, the shielding spring and the insulating body do not need to interfere with each other. When assembling the shielding sheet and the insulating body, it is only necessary to insert the latching arms on both sides of the shielding sheet tightly along the side wall between the top and bottom of the receiving cavity, so that they intersect and are locked in place in a direction parallel to the side wall of the receiving cavity. In this way, the firmness of the fixing between the shielding sheet and the insulating body is independent of the material of the shielding sheet itself. The shielding sheet will not detach from the insulating body due to damage or aging of the insulating body material, thereby greatly improving the electromagnetic shielding performance and reliability of this application.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.
[0030] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0031] The preferred embodiments of this utility model will now be further described with reference to the accompanying drawings. Figure 1 and Figure 2 As shown, an improved male connector includes a metal housing 10 and an insulating body 20 enclosed by the metal housing 10. A terminal assembly 30 is installed within the insulating body 20, and a spacer 33 is provided within the terminal assembly 30. A receiving cavity 21 is provided within the insulating body 20, and a connection port 22 is formed on one side of the receiving cavity 21 for inserting other connector females. Shielding plates 100 are respectively provided at the top and bottom of the receiving cavity 21. Each shielding plate 100 includes a shielding portion 110, which covers the top and bottom of the receiving cavity 21. Clamping arms 120 extend from the sides of the shielding portion 110 near the connection port 22 towards the sidewall between the top and bottom of the receiving cavity 21. A bent portion 130 is formed between the clamping arms 120 and the shielding portion 110. The clamping arms 120 are interlocked and form a latching fixation in a direction parallel to the sidewall of the receiving cavity 21.
[0032] During assembly in this embodiment, the shielding plate 100 is first installed on the top and bottom of the receiving cavity 21. The latching arms 120 on both sides of the shielding plate 100 are then inserted tightly along the side wall between the top and bottom of the receiving cavity 21, so that they intersect and latch in a direction parallel to the side wall of the receiving cavity 21. During this process, the shielding part 110 also covers the top and bottom of the receiving cavity 21, thereby forming an electromagnetic shielding layer for the receiving cavity 21, isolating the interior from the external environment, effectively reducing the leakage of electromagnetic radiation generated by the Type-C interface and its connection lines, reducing interference to other electronic devices in the vicinity, and preventing the impact on wireless communication, broadcast television and other signals.
[0033] Compared to existing technologies, the bending portion 130 in this application does not need to be elastic. Therefore, the shielding spring 100 and the insulating body 20 do not need to interfere with each other. When assembling the shielding sheet 100 and the insulating body 20, it is only necessary to insert the latching arms 120 on both sides of the shielding sheet 100 tightly along the side wall between the top and bottom of the receiving cavity 21, so that they intersect and are locked in place in a direction parallel to the side wall of the receiving cavity 21. In this way, the firmness of the fixation between the shielding sheet 100 and the insulating body 20 is independent of the material of the shielding sheet 100 itself. The shielding sheet 100 will not detach from the insulating body 20 due to damage or aging of the insulating body material, thereby greatly improving the electromagnetic shielding performance and reliability of this application.
[0034] Further, based on the above embodiments, such as Figure 2 As shown, when the latching arms 120 intersect each other on the sidewalls of the receiving cavity 21, the ends of the latching arms 120 away from the bending portion 130 bend outwards to form latching portions 121. The latching portions 121 are fixed together. When the latching arms 120 move outwards along the sidewalls of the receiving cavity 21, the latching portions 121 will abut against each other on the sidewalls of the receiving cavity 21 to form a latching form, thereby ensuring that the shielding sheet 100 and the insulating body 20 will not detach from each other.
[0035] In some embodiments, such as Figure 2 As shown, an inclined surface 121a is provided at the end of the latching part 121. The inclined surfaces 121a are parallel to each other. Since the latching arms 120 are interlocked and fixed, during the assembly process, when the latching arms 120 move towards each other along the side wall of the receiving cavity 21, the latching arms 120 will first come into contact with each other and then deflect in the opposite direction. The inclined surface 121a can help the latching part 121 reduce the angle of deflection during the contact process, thereby preventing the latching arms 120 from deflecting too much during the assembly process and thus avoiding the risk of breakage.
[0036] In some embodiments, such as Figure 2 As shown, a groove 121b is provided on the side of the latching arm 120 away from the latching part 121. Even though a slope 121a is provided at the end of the latching part 121, the latching arm 120 will still deviate during assembly. The groove 121b provided on the side of the latching arm 120 away from the latching part 121 can increase the latching arm 120's resistance to deviating, thereby further improving the safety of assembly.
[0037] Furthermore, based on the above embodiments, and combining Figure 2 and Figure 3As shown, a protrusion 121c is provided on the end face of the latching arm 120 facing outward, and an abutment 23 is provided on the insulating body 20 opposite to the protrusion 121c. When the latching arm 120 moves towards each other along the side wall of the receiving cavity 21, the abutment 23 presses against the protrusion 121c, so that the latching arm 120 can squeeze both sides of the receiving cavity 21. In this way, after the latching arm 120 forms a latching fixation in the parallel direction of the side wall of the receiving cavity 21, the abutment 23 presses against the protrusion 121c, so that the latching arm 120 also clamps the insulating body 20 in the vertical direction of the side wall of the receiving cavity 21, thereby making the fixation between the shielding sheet 100 and the insulating body 20 more secure. Preferably, the latching parts 121 have a first redundant space 122, so that under normal conditions, the latching parts 121 do not contact each other. Preferably, the latching arms 120 also clamp the insulating body 20 in the vertical direction of the side wall of the receiving cavity 21 to ensure the fixation between the shielding sheet 100 and the insulating body 20. When the shielding sheet 100 encounters an external force parallel to the side wall of the receiving cavity 21, its latching parts 121 contact each other to form a latching fixation, thereby providing a second guarantee for the fixation between the shielding sheet 100 and the insulating body 20.
[0038] Further, based on the above embodiments, such as Figure 4 As shown, the terminal assembly 30 includes an upper terminal group 31 and a lower terminal group 32. Both the upper terminal group 31 and the lower terminal group 32 include a resilient connecting part 31a, a main body part 31b, and a welding part 31c arranged sequentially. The resilient connecting part 31a is disposed in the receiving cavity 21. When other connector females are inserted, the resilient connecting part 31a is used to form an electrical connection with other connector females. The welding part 31c is used to weld to the circuit board.
[0039] Further, based on the above embodiments, such as Figure 4 As shown, a plurality of receiving grooves 21a are respectively provided at the top and bottom of the receiving cavity 21. The receiving grooves 21a extend vertically through the top and bottom of the receiving cavity 21. The number of receiving grooves 21a is the same as the number of terminals in the upper terminal group 31 and the lower terminal group 32. The positions of the receiving grooves 21a correspond vertically to the elastic connecting parts 31a. When the elastic connecting parts 31a form an electrical connection with other connector females, the elastic connecting parts 31a will tilt upwards towards the top and bottom of the receiving cavity 21 and be received into the receiving grooves 21a, thereby preventing the elastic connecting parts 31a from being squeezed and broken when in contact with other connector females.
[0040] Furthermore, based on the above embodiments, and combining Figure 3 and Figure 5As shown, a plurality of first elastic portions 111 are provided on the side of the shielding portion 110 near the connection port 22. The first elastic portions 111 bend toward the receiving cavity 21. When other connector females form an electrical connection, the first elastic portions 111 contact the connector females and bend outward, thereby preventing the shielding portion 110 from undergoing a phase change as a whole.
[0041] Further, based on the above embodiments, such as Figure 5 , Figure 6 and Figure 7 As shown, a through groove 112 is provided on one side of the first elastic part 111, and an insulating shielding plate 113 is covered on the through groove 112. The insulating shielding plate 113 covers the outside of the receiving groove 21a. This can prevent the elastic connecting part 31a from being squeezed into the receiving groove 21a and thus avoiding contact with the metal shell 10 through the insulating body 20, thereby preventing a short circuit. Second elastic parts 114 are provided at both ends of the insulating shielding plate 113. The second elastic parts 114 bend outward toward the receiving cavity 21, so that when the metal shell The insulating body 20 is enclosed by the metal outer shell 10. The second elastic part 114 then forms a second redundant space 114a between the metal outer shell 10 and the insulating body 20. In this way, even when the elastic connecting part 31a is squeezed into the receiving groove 21a and comes into contact with the insulating shielding plate 113 through the insulating body 20, the insulating shielding plate 113 still has some space to move upward. This can prevent the elastic connecting part 31a from making excessive contact with the insulating shielding plate 113, thereby avoiding damage to the elastic connecting part 31a and the insulating shielding plate 113.
[0042] In some embodiments, such as Figure 5 , Figure 6 and Figure 7As shown, the insulating shielding plate 113 includes a covering end 113a, a slot 113b is provided at one end of the covering end 113a, a first inclined portion 113c is provided at the top of the slot 113b, an insert plate 112a is provided inside the through groove 112, and a second inclined portion 112b is provided at the top of the insert plate 112a. When the insulating shielding plate 113 covers the through groove 112, the insert plate 112a is inserted into the slot 113b and contacts the first inclined portion 113c and the second inclined portion 112b. Thus, when the elastic connecting portion 31a is squeezed into the receiving groove 21a and passes through the insulating body 20 to contact the insulating shielding plate 113, due to the... When the insert plate 112a is inserted into the slot 113b, the insulating shielding plate 113 will not be lifted up as a whole, but one end will tilt upwards. The tilting angle depends on the angle between the first inclined part 113c and the second inclined part 112b. In this way, when the elastic connecting part 31a is no longer with the insulating shielding plate 113, the insulating shielding plate 113 will still cover the slot 113b without any positional movement. In addition, preferably, the thickness h of the covering end 113a is between 0.08 and 0.12 mm. This size can ensure the insulating shielding effect of the insulating shielding plate 113 and also ensure that the second redundant space 114a has enough space for the insulating shielding plate 113 to tilt upwards.
[0043] The details of the above exemplary embodiments are provided, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all changes falling within the meaning and scope of equivalents of the claims be included within the present invention.
