Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrical connectors, in particular to a multifunctional integrated electrical connector. BACKGROUND

[0002] The multifunctional integrated electrical connector is an electrical connector integrating multiple functions, which can realize the transmission of power, signal, data and other types in one connector, has the characteristics of high integration, multifunction, miniaturization, etc., and is widely used in electronic, electrical, communication and other fields. In order to ensure the stability of the connection, the electrical connector usually adopts the buckle clamping mode.

[0003] The patent document with publication number CN223462544U discloses an electrical connector assembly, which comprises a first connector and a second connector. The first connector is provided with a shielding connection shell, and a buckle is fixedly arranged at one end of the shielding connection shell. The first electrical connector and the second electrical connector are clamped by the buckle. However, the buckle will deform after long-term use, which will weaken the connection force of the connector and affect the connection strength of the connector. SUMMARY

[0004] Therefore, it is necessary to provide a multifunctional integrated electrical connector to solve the technical problem of weak connection strength of the current connector.

[0005] The above-mentioned purpose is realized by the following technical scheme:

[0006] The multifunctional integrated electrical connector comprises a female connector, a male connector and a pressing piece. The female connector comprises a first conductive shell, a first conductive ring coaxially arranged inside the first conductive shell, a first ring groove coaxially arranged on the inner circumferential surface of the first conductive shell, a second ring groove coaxially arranged on the outer circumferential surface of the first conductive ring, and a first insulating layer arranged between the first conductive shell and the first conductive ring. The male connector comprises a second conductive shell, a second conductive ring coaxially arranged inside the second conductive shell, and a second insulating layer arranged between the second conductive shell and the second conductive ring. The second conductive shell is coaxially provided with a first buckle inside, and the first buckle can slide along the axial direction of the second conductive shell. The second conductive ring is coaxially provided with a second buckle. The pressing piece is located between the first buckle and the second buckle. When the female connector and the male connector are inserted, the second conductive shell is inserted into the first conductive shell, so that the first buckle is clamped into the first ring groove, and the first conductive ring is inserted into the second conductive ring, so that the second buckle is clamped into the second ring groove. The pressing piece can expand in the radial direction of the second conductive shell between the first insulating layer and the second insulating layer, so as to outwardly push the first buckle to press the first ring groove, and inwardly push the second buckle to press the second ring groove.

[0007] Further, the top pressing member is a ring-shaped air bag, and the ring-shaped air bag and the first buckle, the second buckle and the second insulating layer form a sealed chamber. When the female connector is inserted into the male connector, the second conductive shell slides relative to the first buckle to drive the second buckle to slide relative to the first buckle, so that the ring-shaped air bag moves along the axial direction of the second conductive ring to compress the sealed chamber, so that the pressure in the sealed chamber is increased, and then the ring-shaped air bag is driven to expand radially.

[0008] Further, the outer surface of the ring-shaped air bag is provided with a first protrusion and a second protrusion, the inner circumferential surface of the first buckle is provided with a first groove, and the outer circumferential surface of the second buckle is provided with a second groove. The first protrusion is inserted and matched with the first groove, and the second protrusion is inserted and matched with the second groove.

[0009] Further, the inside of the second conductive shell is coaxially provided with an insertion slot extending along the axial direction of the second conductive shell, the first buckle is slidingly arranged in the insertion slot, and a spring is arranged between the first buckle and the insertion slot. The spring has a tendency to make the first buckle extend out of the insertion slot.

[0010] Further, the second conductive shell is provided with an adjusting member, which can change the maximum length of the first buckle extending out of the insertion slot, so as to change the initial volume of the sealed chamber, and then change the radial expansion degree of the ring-shaped air bag.

[0011] Further, the adjusting member includes an adjusting bolt and a stop block. The second conductive shell is provided with a long hole extending along the axial direction thereof. The adjusting bolt can slide along the long hole. The stop block is slidingly arranged in the insertion slot. The end of the first buckle away from the female connector is provided with a stop ring. The stop block and the stop ring are stop-fitted along the axial direction of the second conductive shell. The stop block is provided with a threaded hole. The adjusting bolt is screwed into the stop block through the long hole, so as to limit the position of the stop block in the insertion slot, and then change the maximum length of the first buckle extending out of the insertion slot.

[0012] Further, the stop block is connected to the inner wall of the insertion slot through a flexible sealing member, and the flexible sealing member is a plastic film.

[0013] Further, the first buckle is provided with a one-way valve, which only allows external gas to enter the sealed chamber.

[0014] Further, a plurality of first slits extending along the axial direction are arranged on the circumference of the first buckle, and a plurality of second slits extending along the axial direction are arranged on the circumference of the second buckle. The first slits enable the first buckle to expand radially outward, and the second slits enable the second buckle to contract radially inward.

[0015] Further, the ring-shaped air bag is made of rubber material.

[0016] The beneficial effects of the present application are:

[0017] The multifunctional integrated electrical connector provided by the present application has the following beneficial effects: first, the top pressing part can long-term support the first buckle and the second buckle, so that the first buckle is pressed against the first ring groove and the second buckle is pressed against the second ring groove, thereby ensuring the connection effect of the multifunctional integrated electrical connector.

[0018] Second, the movement of the annular air bag can reduce the sliding resistance between the first buckle and the second buckle, thereby prolonging the service life of the multifunctional integrated electrical connector. Moreover, the annular air bag is pressed to produce radial expansion, so that a seal is formed between the first insulating layer, the second insulating layer, the first buckle and the second buckle, thereby improving the sealing performance of the multifunctional integrated electrical connector and enhancing the dustproof and waterproof effect.

[0019] Third, when the male connector and the female connector are in a harsh environment, the maximum length of the first buckle extending out of the insertion groove can be made longer by the adjusting part, so as to improve the sealing effect of the multifunctional integrated electrical connector. When the male connector and the female connector are in a normal environment, the maximum length of the first buckle extending out of the insertion groove can be made shorter by the adjusting part, so as to meet the normal sealing requirement of the multifunctional integrated electrical connector.

[0033] As Figures 1 to 8As shown, an embodiment of the present application provides a multifunctional integrated electrical connector, which comprises a female connector 100, a male connector 200 and a pressing piece; the female connector 100 comprises a first conductive shell 101, a first conductive ring 102 coaxially arranged inside the first conductive shell 101, a first ring groove 1011 coaxially arranged on the inner circumferential surface of the first conductive shell 101, a second ring groove 1021 coaxially arranged on the outer circumferential surface of the first conductive ring 102, and a first insulating layer 103 arranged between the first conductive shell 101 and the first conductive ring 102; the male connector 200 comprises a second conductive shell 201, a second conductive ring 202 coaxially arranged inside the second conductive shell 201, and a second insulating layer 203 arranged between the second conductive shell 201 and the second conductive ring 202; the second conductive shell 201 is coaxially provided with a first buckle 204 which can slide along the axial direction of the second conductive shell 201, and the second conductive ring 202 is coaxially provided with a second buckle 2021; the pressing piece is arranged between the first buckle 204 and the second buckle 2021; when the female connector 100 is connected with the male connector 200, the second conductive shell 201 is inserted into the first conductive shell 101, so that the first buckle 204 is buckled into the first ring groove 1011, and the first conductive ring 102 is inserted into the second conductive ring 202, so that the second buckle 2021 is buckled into the second ring groove 1021; the pressing piece can expand along the radial direction of the second conductive shell 201 between the first insulating layer 103 and the second insulating layer 203, so as to outwardly push the first buckle 204 to press the first ring groove 1011, and inwardly push the second buckle 2021 to press the second ring groove 1021.

[0034] Specifically, the first conductive shell 101, the first insulating layer 103 and the first conductive ring 102 are fixedly connected. The second conductive shell 201, the second insulating layer 203 and the second conductive ring 202 are fixedly connected. The second buckle 2021 is arranged on the side of the second conductive ring 202 facing the female connector 100.

[0035] Such design enables the pressing piece to long-term support the first buckle 204 and the second buckle 2021, so as to press the first ring groove 1011 by the first buckle 204 and press the second ring groove 1021 by the second buckle 2021, and ensure the connection effect of the multifunctional integrated electrical connector.

[0036] Further, the top pressing piece is a ring-shaped air bag 205, and a sealed chamber 300 is formed between the ring-shaped air bag 205, the first buckle 204, the second buckle 2021 and the second insulating layer 203. When the female connector 100 and the male connector 200 are plugged, the second conductive shell 201 sliding relative to the first buckle 204 can drive the second buckle 2021 to slide relative to the first buckle 204, so that the ring-shaped air bag 205 can move along the axial direction of the second conductive ring 202 to compress the sealed chamber 300, so as to increase the pressure in the sealed chamber 300, and then drive the ring-shaped air bag 205 to expand radially.

[0037] The movement of the ring-shaped air bag 205 can reduce the sliding resistance between the first buckle 204 and the second buckle 2021, and prolong the service life of the multifunctional integrated electrical connector. Moreover, the ring-shaped air bag 205 is pressed to expand radially, so that the first insulating layer 103, the second insulating layer 203, the first buckle 204 and the second buckle 2021 are all sealed, thereby improving the sealing performance of the multifunctional integrated electrical connector and enhancing the dustproof and waterproof effect.

[0038] Further, the outer surface of the ring-shaped air bag 205 is provided with a first protrusion 2051 and a second protrusion 2052, the inner circumferential surface of the first buckle 204 is provided with a first groove, and the outer circumferential surface of the second buckle 2021 is provided with a second groove. The first protrusion 2051 is plugged and matched with the first groove, and the second protrusion 2052 is plugged and matched with the second groove.

[0039] In this way, the first protrusion 2051 and the first groove are used to connect the ring-shaped air bag 205 and the first buckle 204, and the second protrusion 2052 and the second groove are used to connect the ring-shaped air bag 205 and the second buckle 2021, so that the ring-shaped air bag 205 moves in a track type.

[0040] Further, the inside of the second conductive shell 201 is coaxially provided with a plugging groove, the plugging groove extends along the axial direction of the second conductive shell 201, the first buckle 204 is slidingly arranged in the plugging groove, and a spring (not shown in the figure) is arranged between the first buckle 204 and the plugging groove. The spring has a tendency to make the first buckle 204 extend out of the plugging groove.

[0041] As shown in the initial state, Figure 7 the multifunctional integrated electrical connector is in the first state. At this time, the first buckle 204 extends out of the plugging groove, and the spring makes the first buckle 204 close to the female connector 100 relative to the second buckle 2021, so that the first buckle 204 can be first buckled into the first ring groove 1011, and the second buckle 2021 is then buckled into the second ring groove 1021. In this way, the buckling resistance can be reduced.

[0042] Further, the second conductive shell 201 is provided with an adjusting member, which can change the maximum length of the first clasp 204 extending from the insertion slot, so as to change the initial volume of the sealed chamber 300, and further change the radial expansion degree of the annular air bag 205.

[0043] The longer the maximum length of the first clasp 204 extending from the insertion slot, the larger the initial volume of the sealed chamber 300, so that the second clasp 2021 is clamped into the second ring groove 1021, the larger the compressed volume of the sealed chamber 300, and the larger the pressure in the sealed chamber 300, and further the higher the radial expansion degree of the annular air bag 205, so that the sealing effect of the male connector 200 and the female connector 100 is better. In this regard, when the male connector 200 and the female connector 100 are in a harsh environment, the maximum length of the first clasp 204 extending from the insertion slot can be made longer by the adjusting member, so as to improve the sealing effect of the multifunctional integrated electrical connector. When the male connector 200 and the female connector 100 are in a normal environment, the maximum length of the first clasp 204 extending from the insertion slot can be made shorter by the adjusting member, so as to meet the normal sealing requirements of the multifunctional integrated electrical connector.

[0044] Further, the adjusting member includes an adjusting bolt 206 and a stop block 207, the second conductive shell 201 is provided with a long hole extending along the axial direction thereof, the adjusting bolt 206 can slide along the long hole, the stop block 207 is slidably arranged in the insertion slot, the first clasp 204 is provided with a stop ring 2041 at the end away from the female connector 100, the stop block 207 and the stop ring 2041 are in abutting cooperation along the axial direction of the second conductive shell 201; the stop block 207 has a threaded hole, and the adjusting bolt 206 is screwed into the stop block 207 through the long hole, so as to limit the position of the stop block 207 in the insertion slot, and further change the maximum length of the first clasp 204 extending from the insertion slot. This structure is simple and convenient to disassemble.

[0045] Further, the stop block 207 is connected to the inner wall of the insertion slot through a flexible sealing member 2071, and the flexible sealing member 2071 is a plastic film. The flexible sealing member 2071 can prevent foreign matter from entering the insertion slot, and it is easy to deform, so as to facilitate the sliding of the stop block 207 in the insertion slot.

[0046] Further, the first clasp 204 is provided with a one-way valve 208, which only allows external gas to enter the sealed chamber 300.

[0047] When the first latch 204 slides towards the female connector 100 under the push of the spring, outside air enters the sealed chamber 300 through the gap between the first conductive shell 101 and the second conductive shell 201 and through the one-way valve 208, making the pressure inside the sealed chamber 300 consistent with the outside air pressure. When the first latch 204 and the second latch 2021 slide relative to each other, the sealed chamber 300 is compressed. Since the gas cannot be discharged, the pressure inside the sealed chamber 300 increases, which in turn compresses the annular airbag 205, causing the annular airbag 205 to expand radially.

[0048] Furthermore, the first snap fastener 204 has multiple first slits extending axially in its circumferential direction, and the second snap fastener 2021 has multiple second slits extending axially in its circumferential direction. The first slits allow the first snap fastener 204 to expand radially outward, and the second slits allow the second snap fastener 2021 to contract radially inward. This design makes the first snap fastener 204 and the second snap fastener 2021 easier to deform, thereby making it easier to engage with the first annular groove 1011 and the second annular groove 1021.

[0049] Furthermore, the annular airbag 205 is made of rubber material. This gives the annular airbag 205 wear resistance, extending its service life.

[0050] Based on the above embodiments, the usage principle and working process of the embodiments of the present invention are as follows:

[0051] Initially, the male connector 200 and the female connector 100 are not plugged in. At this time, as follows... Figure 7 As shown, the multifunctional integrated electrical connector is in its first state, with the first latch 204 extending from the insertion slot. Then, depending on the environment of the male connector 200 and the female connector 100, the position of the stop block 207 in the insertion slot is adjusted by changing the position of the adjusting bolt 206 in the elongated hole, thereby adjusting the maximum length of the first latch 204 extending from the insertion slot, and thus changing the initial volume of the sealed chamber 300.

[0052] Then, the first conductive shell 101 is aligned with the second conductive shell 201, and the male connector 200 and the female connector 100 are inserted. At this time, as Figure 6As shown, the multifunctional integrated electrical connector is in the second state. As the plugging proceeds, the first buckle 204 is inserted into the first ring groove 1011, and the first conductive ring 102 is inserted into the second conductive ring 202, at this time the second buckle 2021 has not been inserted into the second ring groove 1021. Then continue to push the second conductive shell 201 and the first conductive shell 101 to plug, because the first buckle 204 is prevented by the first insulating layer 103, so the first buckle 204 remains stationary, the second conductive ring 202 and the second conductive shell 201 slide relative to the first buckle 204 at the same time, so that the second buckle 2021 gradually approaches and is inserted into the second ring groove 1021, at this time the annular air bag 205 generates axial movement and gradually compresses the sealing cavity 300, so that the volume of the sealing cavity 300 decreases and the pressure increases.

[0053] When the first buckle 204 is inserted into the first ring groove 1011, and the second buckle 2021 is inserted into the second ring groove 1021. As shown, at this time the multifunctional integrated electrical connector is in the third state. Because the pressure of the sealing cavity 300 increases, and then the annular air bag 205 generates radial expansion to extrude the first buckle 204 and the second buckle 2021, so that the first buckle 204 is pressed against the first ring groove 1011 and the second buckle 2021 is pressed against the second ring groove 1021, realizing the sealing of the male connector 200 and the female connector 100.

To make the description concise, all possible combinations of the technical features in the above embodiments are not described, but as long as the combination of the technical features does not exist contradictory, it should be considered as the scope of the present disclosure.
