[0039] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0040] See Figure 1-Figure 5 This embodiment discloses a high-speed connector female end structure, including a female end body 101 and a female end conductor assembly 102 fixedly disposed within the female end body 101. The female end body 101 is used to connect with the male end body 103 so that the male end conductor assembly 104 in the male end of the connector and the female end conductor assembly 102 can cooperate with each other to achieve communication. The female end conductor assembly 102 includes a conductor unit 105 and a jacket 106 for covering the conductor unit 105.

[0041] The conductor group unit 105 includes:

[0042] An inner core 107 , the inner core 107 being connected to the cable 129 and the male conductor assembly 104 ;

[0043] An insulator 108 is provided with a mounting hole, and the inner core 107 is fixedly disposed in the mounting hole of the insulator 108;

[0044] an inner conductor 109 , the inner conductor 109 being press-fitted onto one end of the insulator 108 ;

[0045] The outer conductor 110 is used to cover the insulator 108 and then press-fit it onto the inner conductor 109;

[0046] The pressure ring 111 is press-fitted to the cable 129 and then crimped and fixed to the inner conductor 109;

[0047] The surfaces of the inner conductor 109, the outer conductor 110 and the pressure ring 111 are all provided with depressions, and a limiting protrusion is provided on the outer conductor 110, which contacts the end of the outer sleeve 106, and insulating glue 112 is filled between the outer sleeve 106 and the conductor unit 105. The provided insulating glue 112 is used to bond the conductor components and form an integrated structure after solidification.

[0048] In actual use, the present invention is to cover the insulator 108 with the outer conductor 110 and press it onto the inner conductor 109, and then press the inner core 107 and the cable 129 with the pressure ring 111 and the cable 129, and then press the pressure ring 111 and the inner conductor 109 to form an integrated structure. The inner conductor 109, the outer conductor 110 and the pressure ring 111 are all provided with depressions on the surface of the pressure ring 111, so that the injected insulating glue 112 can enter the depression and solidify to form an anti-slip structure. The component is wrapped to achieve the purpose of protection, so that the conductor component and the jacket 106 are connected to form an integrated structure; at the same time, a support plate 114 is provided on the side of the jacket 106, and a side groove connected to the first mounting hole 113 is provided on the female end body. After the conductor unit 105 is installed in the first mounting groove 124, the support plate is located in the side groove, so that the jacket 106 is locked and fixed to prevent it from falling out. The conductor component is wrapped with an insulating layer formed by the insulating glue 112, which can effectively solve the technical problem of loose connection of the cable 129 and affecting signal transmission.

[0049] Furthermore, a first mounting hole 113 and a threaded hole connected to the first mounting hole 113 are provided on the female end body. A screw is provided in the threaded hole. After the end of the screw contacts the outer sleeve 106, it is used to press the outer sleeve 106 into the first mounting hole 113.

[0050] In actual use, the insulating glue 112 can also be used to bond and fix the female end conductor assembly, so that the female end conductor assembly and the outer sleeve 106 are fixed as one, thereby improving the anti-slip effect and avoiding the cable 129 from loosening.

[0051] In some preferred implementation cases, a support plate is provided on the side of the sleeve 106, and a side groove connected to the first mounting hole 113 is provided on the female end body. After the conductor unit 105 is installed in the first mounting groove 124, the support plate is located in the side groove.

[0052] The side grooves and guide plate 114 can play a guiding role, making it more convenient to install the female conductor assembly 102. At the same time, since the outer sleeve 106 is fixed by screws, the side grooves can support the guide plate 114.

[0053] Furthermore, in actual use, an elastic tube 115 is provided at one end of the female end body 101 close to the cable 129. The elastic tube 115 can buffer the cable 129, preventing the cable 129 from bending and affecting the transmission of signals.

[0054] In some preferred embodiments, a sealing sleeve 116 is connected to the end of the elastic tube 115. The diameter of the sealing sleeve 116 gradually decreases away from the elastic tube 115 and forms a sealing contact with the cable 129. This can seal the cable 129 and further provide buffer protection for the cable 129.

[0055] Furthermore, the sealing sleeve 116 has a telescopic portion 117 in the middle thereof, and the telescopic portion 117 is a continuously bent structure. The bent portion can further improve the supporting effect and the effect of buffering and preventing the cable 129 from bending.

[0056] In addition, the present application also discloses a high-speed connector, including a male end and a female end. The male end includes a male end body 103 and a male end conductor assembly 104 fixedly installed in the male end body 103. The female end is the high-speed connector female end structure described above. After the male end body 103 and the female end body 101 are plugged together, the male end conductor assembly 104 and the female end conductor assembly 102 cooperate with each other to achieve communication. The female end body 101 is provided with an anti-mock protrusion 119, and the male end body 103 is provided with a guide groove 118 that matches the anti-mock protrusion 119. The guide groove 118 and the anti-mock protrusion 119 can ensure the insertion of the connector.

[0057] Furthermore, the male body 103 and the female body 101 are locked by a locking unit 120. In this embodiment, the locking unit 120 includes a locking arm 121, a torsion spring and a latch. A mounting groove 124 is provided on the side of the female body 101. The locking arm 121 is hinged in the mounting groove 124 through the latch, so that the locking arm 121 can rotate around the mounting groove 124 of the latch. The torsion spring is installed on the latch, and under the action of the torsion spring, the locking arm 121 moves toward the direction close to the female body 101. A locking portion 125 is provided at the end of the locking arm 121, and a groove 126 is provided on the male body 103 to cooperate with the locking arm 121. A locking groove 127 matching the locking portion 125 is provided in the groove 126.

[0058] In this way, in actual use, after the male end body 103 and the female end body 101 are plugged in, the locking portion 125 on the locking arm 121 is matched with the locking groove 127 under the action of the torsion spring, thereby realizing the locking of the male end body 103 and the female end body 101.

[0059] Furthermore, in actual use, since the torsion spring is prone to accidental contact, the locking unit 120 also includes a sliding sleeve 114 and a spring 128. The female body 101 is provided with a first protrusion 123. The sliding sleeve 114 is slidably mounted on the female body 101. The female body 101 is provided with a first groove 122. The spring 128 is mounted in the first groove 122 and one end of the spring is connected to the sliding sleeve 114. Under the action of the spring 128, the sliding sleeve 114 contacts the first protrusion 123 and limits one end of the locking arm 121 to the groove 126.

[0060] When inserting, press the end of the locking arm 121 so that the locking arm 121 is located in the groove 126. At this time, the sliding sleeve 114 presses the locking arm 121. After the male end body 103 and the female end body 101 are inserted and installed, the sliding sleeve 114 is pushed to move so that the sliding sleeve 114 is separated from the locking arm 121. At this time, the locking arm 121 is under the action of the torsion spring, so that the locking arm 121 cooperates with the locking groove 127 to achieve locking. Then release the sliding sleeve 114, and the sliding sleeve 114 will be reset under the action of the spring 128 and contact the inclined surface provided at the end of the locking arm 121 to support the locking arm 121; the sliding sleeve is provided to ensure the smoothness during assembly. At the same time, the locking arm 121 is supported after locking, which prevents accidental touch and achieves the purpose of secondary locking, and has the advantage of simple structure.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
