Description

Technical Field

[0001] This invention relates to connectors for transmitting signals and power, and more particularly to a connector socket. Background Technology

[0002] Connectors are a common component in electronic engineering technology, used to connect two active devices to transmit current or signals. A connector consists of two parts: a plug and a socket. The socket part mainly includes a socket housing, and power pins or signal pins are fixed inside the socket housing by a mounting plate assembly to transmit power / signal.

[0003] With the pursuit of miniaturization of devices, people hope that connectors can transmit both current and signals in a smaller space. Currently, a large number of connectors that can transmit both signals and power have appeared on the market. These connectors are installed in devices with a small number of components and can transmit power and signals well. However, when there are many electrical components in a narrow space, the quality of signal and power transmission is poor. Summary of the Invention

[0004] In view of the above-mentioned shortcomings in the prior art, the connector socket provided by the present invention solves the problem of poor anti-interference performance between signals when multiple signals are mixed and transmitted in the same socket.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows:

[0006] A connector socket is provided, comprising a socket housing, wherein a mounting cavity is provided through the socket housing, characterized in that the mounting cavity is divided into two independent chambers by a partition, and a plurality of power contacts and a plurality of signal contacts are respectively fixedly mounted in the two chambers by a mounting plate assembly, and at least two radio frequency components are floatingly mounted on the mounting plate assembly where the signal contacts are located by a floating member;

[0007] Both chambers have at least two annular grooves on their inner surfaces that mate with the external plug. A shielding ring is installed in the annular groove away from the mounting plate assembly, and a waterproof sealing ring is installed in the remaining annular grooves. The upper surface of the waterproof sealing ring extends out of the annular groove. The inner surfaces of both chambers away from the external plug mate are provided with strip-shaped slots, and anti-reverse strips are installed in the strip-shaped slots to prevent the mounting plate assembly from sliding out of the chamber.

[0008] Furthermore, a reinforcing post is provided at each of the four corners of the socket housing and the side where it connects with the external plug. A rotation identification sleeve is installed in one of the reinforcing posts on one diagonal line. The outer surface of the top of the rotation identification sleeve is provided with multiple recessed grooves that are recessed toward its center. A screw is provided on the reinforcing post next to the recessed groove to cooperate with the recessed groove and restrict the rotation of the rotation identification sleeve.

[0009] The holes on the indexing sleeve have a chamfered surface on the opening side and an inclined surface inside; the reinforcing column on the other diagonal line has a steel wire threaded sleeve embedded in it, and the socket housing between the reinforcing columns has several mounting holes.

[0010] Furthermore, the radio frequency assembly includes a radio frequency housing and at least two radio frequency pins fixed within the radio frequency housing by a mounting block. The outer surface of the radio frequency pins is provided with a plurality of bosses and grooves that limit and fix the mounting block. The outer surface of the radio frequency housing is provided with an annular boss that cooperates with a floating component to limit the sliding of the radio frequency assembly in the mounting hole of the mounting plate assembly.

[0011] Furthermore, the mounting block is a two-step shaft, wherein the smaller step is a solid body with RF pin mounting holes, and the outer surface of the smaller step is provided with multiple protrusions that fit into the RF housing; the larger step is an annular body with a strip groove that fits into the RF housing.

[0012] Furthermore, the floating component is a metal sleeve that fits tightly with the mounting holes on the mounting plate assembly. One end of the sleeve has multiple spring pieces that are axially inclined toward its center. After the RF component is fitted into the floating component, it floats and fits with the mounting plate assembly.

[0013] Furthermore, the mounting plate assembly includes a first mounting plate, a second mounting plate, and a third mounting plate connected in sequence. The first mounting plate is installed in the upper cavity of the chamber and covers the entire bottom surface of the upper cavity, and is partially located within the socket housing and the partition.

[0014] The second mounting plate is located in the lower cavity of the chamber, and its edge is provided with an annular platform that limits and cooperates with the inner surface of the socket housing. Multiple slots are provided on its lower surface. The surface of the third mounting plate that cooperates with the second mounting plate is provided with an extension that is embedded in the slot of the second mounting plate. The edge of the lower surface of the third mounting plate is provided with an annular platform that cooperates with the anti-reverse strip.

[0015] Furthermore, the first mounting plate is made of a flexible waterproof material.

[0016] Furthermore, the anti-reverse strip includes a strip-shaped block and multiple arc-shaped protrusions integrally formed with the strip-shaped block. The strip-shaped block is installed in the strip-shaped slot and partially extends out of the strip-shaped slot to cooperate with the annular platform on the third mounting plate. An arc-shaped groove is opened on the outer surface of the lower part of the annular platform of the third mounting plate, and the arc-shaped protrusions are embedded in the arc-shaped groove.

[0017] Furthermore, an annular groove is provided at the junction of the socket housing away from the external plug mating side and the outer wall edge of the mounting cavity, and a waterproof sealing ring is installed in the annular groove here.

[0018] The beneficial effects of this invention are as follows: By dividing the mounting cavity into two independent chambers, one chamber is used for the installation of power pins and the other is used for the installation of signal pins and radio frequency pins. Since the signal and power transmission are arranged in different chambers, the mutual interference between power and signal can be reduced.

[0019] In addition, this solution also has a shielding ring installed in the chambers on the power and signal input sides. The shielding ring can further shield the signal in the other chamber to ensure that this solution can achieve interference-free mixed transmission of multiple signals such as power, photoelectric, and radio frequency.

[0020] The waterproof sealing ring in this design can prevent external water and dust from entering the cavity, causing short circuits in the connector socket and affecting the operation of the equipment. Since part of the sealing ring extends into an annular groove, it can flexibly contact the external plug, allowing the external plug to have a certain range of vertical movement after insertion.

[0021] The anti-reverse strip in this design can stably limit the mounting plate assembly within the socket housing, preventing it from sliding within the cavity due to external vibrations, which could cause the plug to loosen and interrupt power and signal transmission.

[0033] The specific embodiments of the present invention are described below to enable those skilled in the art to understand the present invention. However, it should be understood that the present invention is not limited to the scope of the specific embodiments. For those skilled in the art, various changes are obvious as long as they are within the spirit and scope of the present invention as defined and determined by the appended claims. All inventions utilizing the concept of the present invention are protected.

[0034] like Figures 1-5 As shown, the connector socket 1 of this solution includes a socket housing 11, and a mounting cavity is provided through the socket housing 11. The mounting cavity is divided into two independent chambers 111 by a partition 14. Each chamber 111 is divided into an upper chamber 1111 and a lower chamber 1112. The width of the upper chamber 1111 is greater than the width of the lower chamber 1112.

[0035] like Figure 1 and Figure 3 As shown, reinforcing posts 12 are provided at the four corners of the socket housing 11 on the side where it mates with the external plug. The reinforcing posts 12 can greatly improve the strength of the socket housing 11, making the connector socket 1 suitable for collision plugging between chassis and cabinets, and protecting the contact parts.

[0036] An indexing identification sleeve 121 is installed inside a reinforcing post 12 on one diagonal of the connector housing. The top outer surface of the indexing identification sleeve 121 is provided with a plurality of recessed grooves 1211 that are recessed toward its center. In this embodiment, eight recessed grooves 1211 are preferably provided. A screw 122 is provided on the reinforcing post 12 next to the recessed grooves 1211 to cooperate with the recessed grooves 1211 and restrict the rotation of the indexing identification sleeve 121.

[0037] The hole on the indexing sleeve 121 has a chamfered surface on the opening side and an inclined surface 1212 inside; a steel wire threaded sleeve 123 is embedded in the reinforcing column 12 on the other diagonal, and several mounting holes are provided on the socket housing 11 between the reinforcing columns 12.

[0038] The setting of the indexing sleeve 121 enables the connector socket 1 to achieve 64 (8×8) indexing identifications. Since the threads of the socket housing 11 are prone to stripping and loosening under strong vibration after being tightened, the embedded steel wire thread sleeve 123 improves the strength of the threads and can effectively prevent the threads from loosening and stripping under strong vibration after tightening.

[0039] Refer again Figure 2 and Figure 5 In the two chambers 111, a number of power contacts 15 and a number of signal contacts 16 are fixedly installed in the mounting plate assembly 13 respectively. At least two radio frequency components 18 are floatingly installed on the mounting plate assembly 13 where the signal contacts 16 are located via floating members 17.

[0040] This design, through the partition 14, places the power contact 15, signal contact 16, and RF component 18 in different chambers 111, thus avoiding interference when multiple signals are transmitted together. Preferably, this design consists of 24 #12 power contacts 15, 81 #22 signal contacts 16, and 2 #8 quad coaxial contacts (RF contacts), with all contacts using straight-wire termination.

[0041] Both chambers 111 have at least two annular grooves on their inner surfaces that mate with the external plug. A shielding ring 112 is installed in the annular groove away from the mounting plate assembly 13. The shielding ring 112 can further shield the signal of the other chamber 111 to ensure that the connector socket 1 of this solution can achieve interference-free mixed transmission of multiple signals such as power, photoelectric, and radio frequency.

[0042] Waterproof sealing rings 113 are installed in the remaining annular grooves, and the upper surface of the waterproof sealing rings 113 extends out of the annular grooves; the waterproof sealing rings 113 can prevent external water and dust from entering the chamber 111, causing the connector socket 1 to short circuit and affecting the operation of the equipment; since part of the sealing ring extends out of the annular groove, it makes flexible contact with the external plug, so that the external plug can have a certain range of vertical floating after being plugged in.

[0043] The inner surfaces of the two chambers 111 away from the external plug mating side are provided with strip-shaped grooves, and anti-reverse strips 114 are installed in the strip-shaped grooves to prevent the mounting plate assembly 13 from sliding out of the chambers 111. The unique anti-reverse strips can effectively prevent the mounting plate assembly 13 from sliding out of the chambers 111 during the plug and socket mating process, ensuring the reliability of the head and socket mating.

[0044] When in use, the connector socket 1 of this solution can achieve three-level guidance and floating blind mating. The three-level guidance are as follows: the reinforcing post 12 achieves the first-level guidance; the guide surface set at the end of the socket housing 11 achieves the second-level guidance; and the pinholes of the power contact 15, signal contact 16 and radio frequency contact installed on the mounting plate assembly 13 achieve the third-level guidance.

[0045] In one embodiment of the present invention, the mounting plate assembly 13 includes a first mounting plate 131, a second mounting plate 132 and a third mounting plate 133 connected in sequence. The first mounting plate 131 is installed in the upper cavity 1111 of the chamber 111 and covers the entire bottom surface of the upper cavity 1111, and is partially located in the socket housing 11 and the partition 14.

[0046] The first mounting plate 131 of the above structure can fully seal the two upper cavities 1111 to prevent external water from entering the connector; in addition, the first mounting plate 131 is preferably made of flexible material, so that when the connector plug is inserted into the connector socket 1, it can play a certain buffering role to protect the connector plug and the connector socket 1.

[0047] The second mounting plate 132 is located in the lower cavity 1112 of the chamber 111. Its edge is provided with an annular platform 1331 that limits and cooperates with the inner surface of the socket housing 11. Its lower surface is provided with multiple slots. The surface of the third mounting plate 133 that cooperates with the second mounting plate 132 is provided with an extension that is embedded in the slot of the second mounting plate 132. The edge of the lower surface of the third mounting plate 133 is provided with an annular platform 1331 that cooperates with the anti-reverse strip 114.

[0048] Refer again Figure 2 The anti-reverse strip 114 includes a strip block 1141 and a plurality of arc-shaped protrusions 1142 integrally formed with the strip block 1141. The strip block 1141 is installed in the strip groove and partially extends out of the strip groove to cooperate with the annular platform 1331 on the third mounting plate 133. The outer surface of the lower part of the annular platform 1331 of the third mounting plate 133 is provided with an arc groove, and the arc protrusions 1142 are embedded in the arc groove.

[0049] The anti-reverse strip 114 of the above structure is simple in structure and easy to process. The extended strip groove structure cooperates with the annular platform 1331 to achieve positioning. The cooperation between the arc-shaped protrusion 1142 and the arc-shaped groove increases the depth of the anti-reverse strip 114 in the third mounting plate 133 and increases the contact surface, so that even under a large insertion force, the cavity will not be retracted.

[0050] like Figure 6 and Figure 7As shown, the radio frequency assembly 18 includes a radio frequency housing 181 and at least two radio frequency pins 182 that are fixed inside the radio frequency housing 181 by mounting blocks 183. The outer surface of the radio frequency pins 182 is provided with a plurality of bosses and grooves that limit and fix them to the mounting blocks 183, so as to improve the stability of the radio frequency pins 182 after installation and prevent the radio frequency assembly 18 from loosening under external vibration, thus affecting the stable transmission of radio frequency signals.

[0051] The outer surface of the RF housing 181 is provided with an annular boss 1811, which cooperates with the floating member 17 to limit the sliding of the RF component 18 in the mounting hole of the mounting plate assembly 13. After the floating member 17 cooperates with the annular boss 1811, it can not only make the RF component 18 float in the mounting hole of the mounting plate assembly 13, but also limit the RF component 18 from the cavity, thus ensuring reliable RF transmission.

[0052] like Figure 7 As shown, the mounting block 183 is a two-step shaft, with the smaller step being a solid body and having mounting holes for the RF pin 182. The solid body structure can support the middle of the RF pin 182, improving the stability of the installation. The larger step is an annular body, which allows for a certain amount of floating space during insertion, ensuring accurate alignment during blind insertion.

[0053] The outer surface of the small end step is provided with multiple protrusions that cooperate with the RF housing 181 for positioning; the large end step is provided with a strip groove that is also positioned with the RF housing 181. The protrusions and strip grooves ensure the stability of the mounting block 183 fixed in the RF housing 181, and further ensure the stability of the RF pin 182.

[0054] Refer again Figure 7 The floating component 17 is a metal sleeve 171 that fits tightly with the mounting holes on the mounting plate assembly 13. One end of the sleeve has multiple spring pieces 172 that are inclined toward its center. After the radio frequency assembly 18 is fitted into the floating component 17, it floats and fits with the mounting plate assembly 13.

[0055] The floating member 17 of the above structure can realize the installation of RF components 18 with a large diameter range. Since the spring 172 is a thin sheet with great elasticity, it can ensure the stability of RF components 18 with different diameters after installation. Furthermore, during blind insertion, the elastic force provided by the spring 172 can make the RF component 18 float within a certain size range to achieve the stability of blind insertion of the RF component 18. After the spring 172 cooperates with the annular boss 1811 of the RF housing 181, it forms a barb-like connection structure, which can limit the RF component 18 from the cavity.

[0056] like Figure 5As shown, an annular groove is formed at the junction of the socket housing 11 away from the external plug mating side and the outer wall edge of the mounting cavity. A waterproof sealing ring 113 is installed in this annular groove. The waterproof sealing ring 113 can prevent the socket housing 11 from being sealed at the mounting position, thus preventing water from entering the device at the connector socket 1 mounting position.

[0057] In summary, the connector socket 1 of this solution enables the mixed transmission of multiple signals without interference between them during transmission, thus ensuring the quality of all transmitted signals.
