Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a plug connector and a connector assembly. Background Art

[0002] When designing chassis and cabinet grounding or shielding, it is necessary to connect the connector of the chassis and cabinet interface to the chassis and cabinet panel so that the shield layer of the cable connected to the connector is connected to the panel, thereby achieving grounding or shielding effect for the entire link.

[0003] The connection form of the connector assembly in the prior art is as follows Figure 1 As shown, the connector assembly includes a plug connector and a socket connector, the socket connector includes a socket conductive shell 200 fixed on the chassis cabinet panel 100, the plug connector includes a plug front conductive shell 300 that is plugged into and conductively matched with the socket conductive shell 200, and a plug sleeve 400 that is threadedly connected to the rear end of the plug front conductive shell 300.

[0004] A cable 700 is fixedly connected to the plug connector. A shielded conductive component is located within the plug sleeve 400. This component comprises a shielding barrel 501 and a shielding block 502 connected to the rear end of the barrel 501. Shielding block 502 is provided with a transverse through-hole, and a screw 600 is mounted on the shielding block 502, extending into the transverse through-hole. Cable 700 comprises a shielding layer 701, which is twisted together to form a stranded cable shield 702. This stranded cable shield 702 is inserted into the transverse through-hole and secured with screw 600.

[0005] When assembling the plug connector, first install the shielding conductive component and the cable 700 into the plug sleeve 400, and then connect the plug sleeve 400 to the plug front end conductive shell 300. Since the shielding channel of the entire connector assembly is shielding layer 701 → shielding block 502 → shielding cylinder 501 → plug front end conductive shell 300 → socket conductive shell 200 → chassis cabinet panel 100, during the process of connecting the plug sleeve 400 to the plug front end conductive shell 300, it is necessary to make the shielding cylinder 501 conductively contact with the plug front end conductive shell 300.

[0006] Combine Figure 1 and Figure 3 As shown, a tightening structure 401 is provided at the rear of the plug sleeve 400, and the tightening structure 401 has a tightening end surface 4011 facing forward, and the shielding block 502 has a shielding block end surface 5021 facing backward. Before the plug sleeve 400 is connected to the conductive housing 300 at the front end of the plug, there is a gap between the tightening end surface 4011 and the shielding block end surface 5021, as shown in FIG. Figure 3 As the plug sleeve 400 is screwed in, the top end face 4011 contacts the shielding block end face 5021, as shown in FIG. Figure 3 As shown in FIG. 2 b, the pressing end surface 4011 can then push the shielding block 502 and the shielding tube 501 to move forward.

[0007] Combine Figure 1 and Figure 2 As shown, the shielding tube 501 has a shielding tube end face 5011 facing forward, the plug front end conductive housing 300 has a conductive housing end face 301 facing backward, the plug front end conductive housing 300 also has a positioning piece 302 extending backward, and the shielding tube 501 is provided with a positioning groove 5012 with an opening facing forward. Before the pressing end face 4011 pushes the shielding tube 501 to move, there is a gap between the shielding tube end face 5011 and the conductive housing end face 301, as shown in FIG. Figure 2 As shown in a. With the push of the top end face 4011, the shielding tube end face 5011 and the conductive shell end face 301 finally come into contact, as shown in FIG. Figure 2 As shown in FIG. 5 b, the positioning piece 302 is inserted into the positioning groove 5012. At this time, the entire shielding conductive component is in close contact with the conductive housing 300 at the front end of the plug.

[0008] It can be seen that in the prior art, a tightening structure is provided in the plug sleeve 400. During the installation of the plug sleeve 400, the tightening structure pushes the shielding conductive component to move, thereby achieving conductive contact with the conductive shell 300 at the front end of the plug.

[0009] Therefore, existing plug connectors must incorporate a tightening structure within the plug sleeve, resulting in a relatively complex plug sleeve structure. Furthermore, because the plug sleeve is threadedly connected to the front conductive housing of the plug, the degree of screwing of the plug sleeve must be carefully controlled during installation. If the screwing is insufficient, close contact between the shielding conductive component and the front conductive housing of the plug cannot be ensured, thereby affecting the grounding or shielding effectiveness of the link. Therefore, existing plug sleeves are difficult to control during installation and have high installation requirements. Summary of the Invention

[0010] The present invention aims to provide a plug connector that solves the problems in the prior art of requiring a tightening structure within the plug sleeve, which results in a complicated plug sleeve structure, and the prior art of using the screwing degree of the plug sleeve to control the close contact between the shielding conductive component and the front conductive shell of the plug, which results in high requirements for plug sleeve installation and difficulty in control. The present invention also aims to provide a connector assembly that solves the problems in the prior art of requiring a tightening structure within the plug sleeve, which results in a complicated plug sleeve structure, and the prior art of using the screwing degree of the plug sleeve to control the close contact between the shielding conductive component and the front conductive shell of the plug, which results in high requirements for plug sleeve installation and difficulty in control.

[0011] To achieve the above objectives, the plug connector in the present invention adopts the following technical solutions:

[0012] A plug connector, comprising:

[0013] Inner conductive shell;

[0014] A tail sleeve connected to the rear end of the inner conductive shell;

[0015] A first insulator is disposed inside the inner conductive housing and the tail sleeve, a power conductive component is mounted inside the first insulator, the power conductive component includes a plug contact extending from the front end of the first insulator, a second insulator and an elastic washer are disposed outside the plug contact, the elastic washer is located on the rear side of the second insulator and engages with the front end surface of the first insulator, and an annular flange is disposed on the outer surface of the first insulator;

[0016] A shielding conductive component is provided inside the tail sleeve, wherein a fixing structure for fixing the cable shielding layer is provided at the rear end of the shielding conductive component, and a conductive sheet is provided at the front end thereof for engaging with the annular flange on the first insulator;

[0017] a clip spring, disposed outside the first insulator and located at the rear side of the conductive sheet;

[0018] Wherein, a stopping step is provided on the inner wall of the inner conductive shell, and the stopping step cooperates with the second insulator in the front-to-back direction to prevent the second insulator from moving forward;

[0019] The inner wall of the inner conductive shell is also provided with an annular groove for the retaining spring to be inserted into. The annular groove is located on the rear side of the stopping step. The spacing between the annular groove and the stopping step satisfies that after the retaining spring is inserted into the annular groove, the elastic gasket is compressed and applies a backward force to the front end face of the first insulator, so that the annular flange on the first insulator presses the conductive sheet against the end face of the retaining spring, so that the retaining spring and the conductive sheet are in close contact, thereby realizing the conduction of the cable shielding layer with the inner conductive shell through the shielding conductive component and the retaining spring.

[0020] The beneficial effect of the above technical solution is that the power conductive component enables power transmission. The power conductive component is installed in a first insulator, and the plug contact at the front end extends through the first insulator. A second insulator and an elastic gasket are provided on the exterior of the plug contact. When assembled into the inner conductive housing, the second insulator engages with a stop step on the inner wall of the inner conductive housing, thereby preventing the second insulator from moving forward and effectively limiting its position. An annular flange is provided on the first insulator, and the conductive sheet at the front end of the shielding conductive component engages with the annular flange to effectively limit the conductive sheet.

[0021] The plug connector also includes a retaining spring located behind the conductive sheet. An annular retaining groove is provided on the inner wall of the inner conductive housing for the retaining spring to engage. The spacing between the annular retaining groove and the stop step ensures that, after the retaining spring engages the annular retaining groove, the elastic gasket is compressed and exerts a rearward force on the front end face of the first insulator, causing the annular flange on the first insulator to press the conductive sheet against the end face of the retaining spring, thereby achieving close contact between the retaining spring and the conductive sheet. The retaining spring, when engaged in the annular retaining groove, is in close contact with the inner conductive housing. This allows the cable shield to be electrically connected to the inner conductive housing via the shielding conductive component and the retaining spring. In other words, the shielding path of the plug connector is cable shield → fixed structure on the shielding conductive component → conductive sheet on the shielding conductive component → retaining spring → inner conductive housing. Consequently, when the plug connector is mated with the receptacle connector, the inner conductive housing can be electrically connected to the shielding conductor on the receptacle connector, thereby achieving electrical connection with the chassis cabinet panel.

[0022] Therefore, the plug connector of the present invention utilizes the second insulator to cooperate with the inner conductive shell to stop, and then utilizes the retaining spring to clamp into the inner conductive shell to compress the elastic gasket, and utilizes the reaction force of the elastic gasket on the first insulator to tightly press the conductive sheet against the retaining spring to realize the formation of a shielding channel.

[0023] It can be seen that the present invention does not need to set a tightening structure on the tail sleeve, which can simplify the structure of the tail sleeve. At the same time, the tail sleeve is no longer used to tighten the shielded conductive component, but a retaining spring, an annular groove, a second insulator and a stopping step are used. During installation, it is only necessary to use a tool to clamp the retaining spring into the annular groove. The installation is relatively convenient and can ensure close contact, thereby ensuring the grounding or shielding effect of the link.

[0024] Furthermore, in order to ensure the contact area and facilitate installation, the conductive sheet is an arc-shaped conductive sheet, and the arc-shaped conductive sheet is C-shaped.

[0025] Furthermore, in order to make the structure compact, the axial width of the annular flange is uneven in the circumferential direction, so that the rear end face of the annular flange has a step structure. The rear end face of the annular flange includes a first stop face at the front and a second stop face at the rear. The front end face of the arc-shaped conductive sheet is engaged with the first stop face, and the arc-shaped conductive sheet is clamped between the first stop face and the retaining spring.

[0026] Furthermore, in order to ensure uniform contact area and force on the retaining spring, the circumferential length of the retaining spring is greater than the circumferential length of the arc-shaped conductive sheet, and the front end surface of the retaining spring is simultaneously engaged with the second stop surface and the rear end surface of the arc-shaped conductive sheet.

[0027] Furthermore, in order to increase the contact area, the outer diameter of the arc-shaped conductive sheet is equal to the outer diameter of the annular flange.

[0028] Furthermore, in order to increase the contact area and facilitate the installation of the arc-shaped conductive sheet, the circumferential length of the arc-shaped conductive sheet exceeds half the circumference, and parallel planes are processed on the inner walls at both ends of the arc-shaped conductive sheet. The distance between the two parallel planes is greater than the outer diameter of the first insulator, so that the arc-shaped conductive sheet can be directly installed to the outside of the first insulator in the up and down directions.

[0029] Furthermore, in order to facilitate the fixation of the cable shielding layer, the fixing structure includes a wire pressing block and a wire clamp, one end of the wire clamp is hinged on the wire pressing block, and the other end is fixedly connected to the wire pressing block by a fastening screw. An installation space is formed between the wire pressing block and the wire clamp for the cable to pass through and clamp the cable shielding layer.

[0030] Furthermore, in order to facilitate the processing, manufacturing, installation and fixation of the shielding conductive components, the shielding conductive components include an intermediate shielding plate, the conductive plate is arranged at the front end of the intermediate shielding plate, the fixing structure is arranged at the rear end of the intermediate shielding plate, and the left and rear sides of the intermediate shielding plate are respectively provided with a hook and an elastic locking plate, the elastic locking plate is located on the front side of the hook, and a sliding groove for the hook to slide back and forth is provided on the first insulator, and a blocking block is provided on the groove wall of the sliding groove for blocking and cooperating with the hook in the up and down directions after the hook slides into place, and a locking block is also provided on the groove wall of the sliding groove, and the locking block is located on the front side of the locking block. The locking block is used to block and cooperate with the elastic locking plate in the front and back directions after the elastic locking plate moves forward into place, and a locking groove for the elastic locking plate to be embedded is formed on the front side of the locking block.

[0031] Furthermore, in order to facilitate the manufacture and installation of shielded conductive components, the intermediate shielding piece is a flat sheet structure, the first insulator is provided with a fitting plane that fits with the intermediate shielding piece, a boss is provided on the fitting plane, and the intermediate shielding piece is provided with an avoidance hole for avoiding the boss.

[0032] To achieve the above objectives, the connector assembly of the present invention adopts the following technical solutions:

[0033] A connector assembly includes a socket connector and a plug connector, wherein the plug connector includes:

[0034] Inner conductive shell;

[0035] A tail sleeve connected to the rear end of the inner conductive shell;

[0036] A first insulator is disposed inside the inner conductive housing and the tail sleeve, a power conductive component is mounted inside the first insulator, the power conductive component includes a plug contact extending from the front end of the first insulator, a second insulator and an elastic washer are disposed outside the plug contact, the elastic washer is located on the rear side of the second insulator and engages with the front end surface of the first insulator, and an annular flange is disposed on the outer surface of the first insulator;

[0037] A shielding conductive component is provided inside the tail sleeve, wherein a fixing structure for fixing the cable shielding layer is provided at the rear end of the shielding conductive component, and a conductive sheet is provided at the front end thereof for engaging with the annular flange on the first insulator;

[0038] a clip spring, disposed outside the first insulator and located at the rear side of the conductive sheet;

[0039] Wherein, a stopping step is provided on the inner wall of the inner conductive shell, and the stopping step cooperates with the second insulator in the front-to-back direction to prevent the second insulator from moving forward;

[0040] The inner wall of the inner conductive shell is also provided with an annular groove for the retaining spring to be inserted into. The annular groove is located on the rear side of the stopping step. The spacing between the annular groove and the stopping step satisfies that after the retaining spring is inserted into the annular groove, the elastic gasket is compressed and applies a backward force to the front end face of the first insulator, so that the annular flange on the first insulator presses the conductive sheet against the end face of the retaining spring, so that the retaining spring and the conductive sheet are in close contact, thereby realizing the conduction of the cable shielding layer with the inner conductive shell through the shielding conductive component and the retaining spring.

[0041] The beneficial effect of the above technical solution is that the power conductive component enables power transmission. The power conductive component is installed in a first insulator, and the plug contact at the front end extends through the first insulator. A second insulator and an elastic gasket are provided on the exterior of the plug contact. When assembled into the inner conductive housing, the second insulator engages with a stop step on the inner wall of the inner conductive housing, thereby preventing the second insulator from moving forward and effectively limiting its position. An annular flange is provided on the first insulator, and the conductive sheet at the front end of the shielding conductive component engages with the annular flange to effectively limit the conductive sheet.

[0042] The plug connector also includes a retaining spring located behind the conductive sheet. An annular retaining groove is provided on the inner wall of the inner conductive housing for the retaining spring to engage. The spacing between the annular retaining groove and the stop step ensures that, after the retaining spring engages the annular retaining groove, the elastic gasket is compressed and exerts a rearward force on the front end face of the first insulator, causing the annular flange on the first insulator to press the conductive sheet against the end face of the retaining spring, thereby achieving close contact between the retaining spring and the conductive sheet. The retaining spring, when engaged in the annular retaining groove, is in close contact with the inner conductive housing. This allows the cable shield to be electrically connected to the inner conductive housing via the shielding conductive component and the retaining spring. In other words, the shielding path of the plug connector is cable shield → fixed structure on the shielding conductive component → conductive sheet on the shielding conductive component → retaining spring → inner conductive housing. Consequently, when the plug connector is mated with the receptacle connector, the inner conductive housing can be electrically connected to the shielding conductor on the receptacle connector, thereby achieving electrical connection with the chassis cabinet panel.

[0043] Therefore, the plug connector of the present invention utilizes the second insulator to cooperate with the inner conductive shell to stop, and then utilizes the retaining spring to clamp into the inner conductive shell to compress the elastic gasket, and utilizes the reaction force of the elastic gasket on the first insulator to tightly press the conductive sheet against the retaining spring to realize the formation of a shielding channel.

[0044] It can be seen that the present invention does not need to set a tightening structure on the tail sleeve, which can simplify the structure of the tail sleeve. At the same time, the tail sleeve is no longer used to tighten the shielded conductive component, but a retaining spring, an annular groove, a second insulator and a stopping step are used. During installation, it is only necessary to use a tool to clamp the retaining spring into the annular groove. The installation is relatively convenient and can ensure close contact, thereby ensuring the grounding or shielding effect of the link.

[0045] Furthermore, in order to ensure the contact area and facilitate installation, the conductive sheet is an arc-shaped conductive sheet, and the arc-shaped conductive sheet is C-shaped.

[0046] Furthermore, in order to make the structure compact, the axial width of the annular flange is uneven in the circumferential direction, so that the rear end face of the annular flange has a step structure. The rear end face of the annular flange includes a first stop face at the front and a second stop face at the rear. The front end face of the arc-shaped conductive sheet is engaged with the first stop face, and the arc-shaped conductive sheet is clamped between the first stop face and the retaining spring.

[0047] Furthermore, in order to ensure uniform contact area and force on the retaining spring, the circumferential length of the retaining spring is greater than the circumferential length of the arc-shaped conductive sheet, and the front end surface of the retaining spring is simultaneously engaged with the second stop surface and the rear end surface of the arc-shaped conductive sheet.

[0048] Furthermore, in order to increase the contact area, the outer diameter of the arc-shaped conductive sheet is equal to the outer diameter of the annular flange.

The locking block 55 is used to cooperate with the elastic locking piece 77 in the front and rear directions after the elastic locking piece 77 moves forward into position. A locking groove 53 is formed on the front side of the locking block 55 for the elastic locking piece 77 to be embedded in.

[0079] In addition, the circumferential length of the arc-shaped conductive sheet 71 exceeds half the circumference, and parallel planes are processed on the inner walls at both ends of the arc-shaped conductive sheet 71. The distance between the two parallel planes is greater than the outer diameter of the column of the first insulator 5, so that the arc-shaped conductive sheet 71 can be directly installed on the outside of the column of the first insulator 5 in the up and down directions.

[0080] like Figure 11 As shown in (a), the entire shielding conductive component 7 is placed above the first insulator 5, and then the shielding conductive component 7 is installed on the first insulator 5 from top to bottom, as shown in FIG. Figure 11 As shown in (b), the hook 76 is now located in the slide groove 54 and staggered with the block 56, the elastic locking piece 77 is located outside the locking block 55, the boss 52 passes through the avoidance hole 78, and the middle shielding piece 70 is in contact with the contact plane 57. Then push the shielding conductive component 7 forward, as shown in FIG. Figure 11 As shown in (c), the hook 76 is moved below the block 56. The block 56 and the hook 76 engage in a vertical blocking motion, preventing the shielding conductive component 7 from dislodging upward. Simultaneously, the elastic locking piece 77 passes over the locking piece 55 and moves into the locking slot 53. The locking piece 55 and the elastic locking piece 77 engage in a forward and backward blocking motion, preventing the shielding conductive component 7 from dislodging backward. Simultaneously, the annular flange 51 contacts and engages with the arcuate conductive piece 71, securing the shielding conductive component 7. Thus, the shielding conductive component 7 and the first insulator 5 are assembled.

[0081] like Figure 6As shown in (a), the power conductive component 9 includes a tightening screw 92 threadedly connected to the power conductive component 9. The tightening screw 92 is used to tighten the cable conductor (not shown in the figure) of the cable 1000 after it passes through the power conductive component 9, thereby fixing the cable conductor and achieving conduction with the power conductive component 9.

[0082] When installing the power conductive component 9 into the first insulator 5, it is necessary to first screw the locking screw 92 into the power conductive component 9 to prevent screw interference and prevent installation. The first insulator 5 is provided with an exposure hole (not shown) corresponding to the locking screw 92, so that a tool can be inserted through the exposure hole to tighten the locking screw 92. After the power conductive component 9 is installed in the first insulator 5, the front plug contact 91 extends out of the first insulator 5, and the elastic washer 4 and the second insulator 3 are sequentially placed on the outside of the plug contact 91, as shown in FIG. Figure 6 As shown in (b), the elastic washer 4 is not squeezed. At the same time, the clamping spring 6 is sleeved on the outside of the first insulator 5 so that the clamping spring 6 is located at the rear side of the arc-shaped conductive piece 71.

[0083] Then the whole composed of the first insulator 5, the shielding conductive component 7, the power conductive component 9, the elastic washer 4, the second insulator 3 and the clamping spring 6 is connected to the inner conductive shell 2, as shown in FIG. Figure 6 As shown in (c), the whole is inserted into the inner conductive shell 2 from back to front, and combined with Figure 9 As shown, a stopping step 22 is provided on the inner wall of the inner conductive shell 2 , and the stopping step 22 cooperates with the second insulator 3 in the front-to-back direction to prevent the second insulator 3 from moving forward, which is equivalent to limiting the second insulator 3 .

[0084] Then push the whole thing forward to compress the elastic washer 4 and combine Figure 8 As shown, the inner wall of the inner conductive housing 2 is also provided with an annular groove 21 for the retaining spring 6 to engage. The annular groove 21 is located behind the stop step 22, so that the retaining spring 6 can be operated with a special tool to engage the annular groove 21. The spacing between the annular groove 21 and the stop step 22 is sufficient to ensure that after the retaining spring 6 is engaged with the annular groove 21, the compressed elastic washer 4 applies a backward force to the front end surface of the first insulator 5, causing the annular flange 51 on the first insulator 5 to press the arc-shaped conductive sheet 71 against the end surface of the retaining spring 6, thereby ensuring close contact between the retaining spring 6 and the arc-shaped conductive sheet 71. Of course, at this time, the retaining spring 6 and the annular groove 21 are engaged in the front-to-back direction, and are in close contact with the inner conductive housing 2, preventing the entire retaining spring 6 from moving backward, thereby achieving a fully engaged retaining assembly on the inner conductive housing 2.

[0085] Combine Figure 7 and Figure 11As shown in (a), the axial width of the annular flange 51 is uneven in the circumferential direction, so that the rear end surface of the annular flange 51 has a stepped structure. The rear end surface of the annular flange 51 includes a first stop surface 511 located forward and a second stop surface 512 located rearward. The front end surface of the arcuate conductive sheet 71 is engaged with the first stop surface 511, and the arcuate conductive sheet 71 is sandwiched between the first stop surface 511 and the retaining spring 6. Furthermore, the circumferential length of the retaining spring 6 is greater than the circumferential length of the arcuate conductive sheet 71, and the front end surface of the retaining spring 6 is engaged with both the second stop surface 512 and the rear end surface of the arcuate conductive sheet 71.

[0086] Figure 6 The integral part shown in (c) is formed after connecting the cable 1000, the tail sleeve 8, and the outer shell 1. Figure 4 Plug connector shown.

[0087] In the plug connector of the present invention, the cable shielding layer 1001 is connected to the inner conductive shell 2 through the shielding conductive component 7 and the clamping spring 6. That is, the shielding path of the plug connector is the cable shielding layer 1001 → the wire clamp 72 and the wire pressing block 73 on the shielding conductive component 7 → the arc-shaped conductive sheet 71 on the shielding conductive component 7 → the clamping spring 6 → the inner conductive shell 2. Figure 12 As shown, when the plug connector is plugged into the socket connector 2000 , the inner conductive shell 2 can be in contact with the socket conductive shell 2001 and then connected to the chassis cabinet panel 3000 through the socket shielding conductive spring 2002 .

[0088] Therefore, the plug connector of the present invention utilizes the second insulator 3 to cooperate with the inner conductive shell 2 to stop, and then utilizes the retaining spring 6 to be clamped into the inner conductive shell 2 to compress the elastic gasket 4, and utilizes the reaction force of the elastic gasket 4 on the first insulator 5 to tightly press the arc-shaped conductive sheet 71 against the retaining spring 6 to form a shielding channel.

[0089] It can be seen that the present invention does not need to set a tightening structure on the tail sleeve 8, which can simplify the structure of the tail sleeve 8. At the same time, the tail sleeve 8 is no longer used to tighten the shielding conductive component, but a retaining spring, an annular groove, a second insulator and a stopping step are used. During installation, it is only necessary to use a tool to clamp the retaining spring into the annular groove. The installation is relatively convenient and can ensure close contact, thereby ensuring the grounding or shielding effect of the link.

[0090] In other embodiments of the connector assembly, the intermediate shielding piece may also be arc-shaped. In this case, there is no need to provide a fitting plane on the first insulator, and there is no need to provide an avoidance hole on the intermediate shielding piece.

[0091] In other embodiments of the connector assembly, the shielding conductive component may also be cylindrical and sleeved and fixed on the outside of the first insulator.

[0092] In other embodiments of the connector assembly, the fixing structure is not a wire clamp and a wire pressing block, but a fixing block and a screw installed on the fixing block. The fixing block is provided with a transverse through-hole. In this case, the cable shielding layer needs to be twisted into a strand to form a stranded cable shield. The stranded cable shield is inserted into the transverse through-hole and tightened by the screw.

[0093] In other embodiments of the connector assembly, the circumferential length of the arc-shaped conductive piece is less than half the circumference, and in this case, there is no need to process a flat surface on the end portion.

[0094] In other embodiments of the connector assembly, the outer diameter of the arc-shaped conductive piece may be smaller than the outer diameter of the annular flange.

[0095] In other embodiments of the connector assembly, the circumferential length of the clamping spring may be equal to the circumferential length of the arc-shaped conductive piece.

[0096] In other embodiments of the connector assembly, regardless of whether the circumferential length of the retaining spring is greater than the circumferential length of the arc-shaped conductive sheet, the front end face of the retaining spring can be simultaneously engaged with the second stop face and the rear end face of the arc-shaped conductive sheet by circumferentially offsetting the retaining spring and the arc-shaped conductive sheet.

[0097] In other embodiments of the connector assembly, the front end surface of the clamping spring may only be engaged with the rear end surface of the arc-shaped conductive sheet, that is, the front end surface of the clamping spring does not contact the second stopping surface.

[0098] In other embodiments of the connector assembly, the axial width of the annular flange can be uniform in the circumferential direction, that is, the rear end face of the annular flange is flat, and the front end face of the arc-shaped conductive sheet directly engages with the rear end face of the annular flange.

[0099] In other embodiments of the connector assembly, the arc-shaped conductive piece may not be C-shaped, but may be a shorter inferior arc shape.

[0100] In other embodiments of the connector assembly, the conductive piece may not be arc-shaped, but may be rectangular or elliptical.

[0101] The embodiment of the plug connector in the present invention is as follows: The specific structure of the plug connector is the same as that of the plug connector in the above connector assembly embodiment, and will not be repeated here.

[0102] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be based on the claims. Any equivalent structural changes made using the description and drawings of the present invention shall be included in the scope of protection of the present invention.
