Example

[0034] This embodiment provides an underwater detachable connector 100, referring to Figure 1 As shown, it includes a plug 110 , a socket 120 and a transition assembly 140 .

[0035] Among them, Figure 2 and Figure 3 As shown, the side of the socket 120 facing the plug 110 is recessed with a first receiving groove 121. The adapter assembly 140 is placed in the first receiving groove 121 and is detachably connected to the bottom of the first receiving groove 121. An annular slot 141 is formed between the outer side of the adapter assembly 140 and the wall of the first receiving groove 121. The side of the plug 110 facing the socket 120 is protruding with an annular plug-in portion 111 for plugging into the annular slot 141. The plug-in portion 111 surrounds the second receiving groove 112. When the header is plugged in, the adapter assembly 140 fits into the second receiving groove 112, and the plug-in portion 111 fits into the first receiving groove 121, forming an overlapping plug-in connection, which significantly improves the tightness of the plug-in connection.

[0036] In addition, if Figure 2 and Figure 4As shown, the adapter assembly 140 has a plurality of first wire spring positioning holes 142 on the side facing the first receiving groove 121. A plurality of first pins 122 are provided through the bottom of the first receiving groove 121, which engage with the first wire spring positioning holes 142. The plurality of first wire spring positioning holes 142 correspond one-to-one with the first pins 122. The adapter assembly 140 has a plurality of second wire spring positioning holes 143 on the side facing the second receiving groove 112. A plurality of second pins 113 are provided through the bottom of the second receiving groove 112, which engage with the second wire spring positioning holes 143. The plurality of second wire spring positioning holes 143 correspond one-to-one with the second pins 113. The plurality of first wire spring positioning holes 142 and the plurality of second wire spring positioning holes 143 are electrically connected in a one-to-one correspondence. In the prior art, the adapter assembly 140 is typically connected to the plug 110 using a combination of wire springs and pins, while the adapter assembly 140 and the receptacle 120 are connected by metal key end-face contact. This end-face contact method, however, places high demands on the secure connection between adapter assembly 140 and socket 120, typically employing a threaded connection for locking. This connection method, however, can easily become loose as the device ages, leading to electrical failure between adapter assembly 140 and socket 120. To address this issue, the present invention incorporates wire springs on both sides of adapter assembly 140. This effectively maintains electrical continuity between the two components, even if they become loose, ensuring a reliable connection.

[0037] Furthermore, if Figure 3 and Figure 5 As shown, the socket 120 includes a first glass disc 123 and a first guide pin 124. A first mating hole 1211 is provided through the center of the bottom of the first accommodating groove 121, into which the first glass disc 123 is embedded. A second mating hole is provided in the center of the first glass disc 123, into which the first guide pin 124 is embedded. The first guide pin 124, the first glass disc 123, and the wall of the first mating hole 1211 are sintered integrally. Due to this structural design, during processing and production, the housing of the socket 120 and the first guide pin 124 are separate and independent parts. They are only connected and formed during the sintering process to form the first glass disc 123. Furthermore, the housing of the socket 120 only requires simple hole drilling, which greatly simplifies processing difficulty, reduces processing costs, and is more conducive to large-scale production. The plurality of first pins 122 extend through the first glass disc 123 along its axis and are evenly distributed around the first guide pin 124. The plurality of first pins 122 are integrally sintered with the first glass disc 123. During the sintering process, the plurality of first pins 122 are secured.

[0038] like Figure 4 and Figure 5 As shown, first guide pin 124 includes a fixed end 1241 connected to first glass disc 123 and a free end 1242 extending into first receiving groove 121. A positioning hole 144 is recessed inwardly on the side of adapter assembly 140 facing first glass disc 123, into which free end 1242 fits. The outer circumference of free end 1242 is provided with a first flat surface 1242a, and the interior of positioning hole 144 is provided with a second flat surface 1441 corresponding to the flat surface. During installation, adapter assembly 140 is quickly installed by inserting free end 1242 into positioning hole 144. Due to the design of the first flat surface 1242a and the second flat surface 1441, the first guide pin 124 can be smoothly inserted into the positioning hole 144 only when the first flat surface 1242a and the second flat surface 1441 are aligned. After insertion, the first guide pin 124 and the adapter assembly 140 can no longer rotate relative to each other, thereby completing the rotation angle positioning of the adapter assembly 140 and the first guide pin 124.

[0039] Furthermore, if Figure 6 As shown, free end 1242 is provided with a screw hole 1243, which is arranged along the axis of first guide pin 124. Connector receptacle 120 also includes a screw 150 that is threadedly engaged with screw hole 1243. The bottom of positioning hole 144 is provided with a through hole 145 for screw 150 to pass through. After first guide pin 124 is inserted into positioning hole 144, screw 150 is tightened to secure adapter assembly 140 to first guide pin 124.

[0040] On the side of adapter assembly 140 facing away from first glass disc 123, a circular groove 146 is provided to accommodate the nut portion of screw 150. The bottom of groove 146 communicates with positioning hole 144 via through-hole 145. The depth of groove 146 is greater than the thickness of the nut portion of screw 150. After screw 150 is tightened, the nut portion will be embedded in groove 146, preventing the nut portion from protruding from the surface of adapter assembly 140 and hindering the insertion of socket 120 and plug 110. A nut 147 is disposed between free end 1242 and the bottom of positioning hole 144. Nut 147 can threadably engage screw 150, thereby securing screw 150.

[0041] like Figure 4 and Figure 5As shown, first glass disc 123 also has a first guide post 125 disposed along its axis, eccentrically positioned between first guide post 125 and first glass disc 123. Adapter assembly 140 is provided with a guide hole 148 for plugging with first guide post 125. The eccentrically positioned first guide post 125 creates a new connection point beyond first guide pin 124, further ensuring the correct installation position of adapter assembly 140. Guide hole 148 extends through adapter assembly 140 along its axis. This allows air to quickly escape from the other end during insertion of first guide post 125, preventing air resistance and ensuring a smooth insertion process.

[0042] Likewise, if Figure 7 and Figure 8 As shown, plug 110 includes a second glass disc 114 and a second guide pin 115. A third mating hole is provided in the middle of the bottom of the second accommodating groove 112, into which the second glass disc 114 is inserted. A fourth mating hole is provided in the middle of the second glass disc 114, into which the second guide pin 115 is inserted. The second guide pin 115, the second glass disc 114, and the wall of the fourth mating hole are sintered integrally. This design also reduces the difficulty of manufacturing the plug 110 housing and the second guide pin 115, further facilitating large-scale production. Multiple second pins 113 extend through the second glass disc 114 along its axis and are evenly distributed around the second guide pin 115. The multiple second pins 113 are sintered integrally with the second glass disc 114. In addition, when designing the circular groove 146 , its depth is intentionally designed to be greater than the thickness of the nut. The extra space is just enough for the second guide pin 115 to be inserted, thereby utilizing the second guide pin 115 to form a positioning effect.

[0043] Furthermore, second glass disc 114 also has a second guide post 116 disposed along its axis, eccentrically positioned between second glass disc 114. The position of second guide post 116 corresponds to guide hole 148 and allows for insertion and mating with guide hole 148. When the header is inserted into the socket, second guide post 116 is inserted into guide hole 148 to help position plug 110 for insertion. It is important to note that the overall length of guide hole 148 is greater than the combined length of the inserted portions of first and second guide posts 125, 116, to ensure smooth insertion of plug 110 and socket 120.

[0044] In addition, Figure 4 and Figure 9As shown, the outer surface of the adapter assembly 140 is provided with an inwardly recessed positioning groove 149, which extends axially through the adapter assembly 140. A positioning block 117 is provided protruding from the wall of the second accommodating groove 112 and slidably engages with the positioning groove 149. The cooperation between the positioning groove 149 and the positioning block 117 further ensures that the plug 110 is inserted at the correct angle, allowing the multiple second pins 113 to be smoothly inserted into the multiple second wire spring positioning holes 143.

[0045] It's worth noting that, to prevent the adapter assembly 140 and the receptacle 120 from disengaging, existing connectors typically reinforce the adapter assembly 140 by adding a fixing structure to the walls of the first receiving groove 121. This approach consumes the outer surface of the adapter assembly 140, reducing its contact area with the second receiving groove 112 and weakening the tightness of the insertion. However, the adapter assembly 140 of the present application utilizes a double-sided coil spring structure. To accommodate the coil springs on both sides, it is already thicker than a typical adapter assembly 140. Furthermore, without the need for external fixings, the contact area between the adapter assembly 140 and the second receiving groove 112 is significantly increased. Similarly, this ample contact area allows the inventors to more conveniently design air storage spaces on the walls of the second receiving groove 112 and the first receiving groove 121 to store air. These air storage spaces reduce the reaction force generated by the air during the insertion and removal of the plug 110 and the receptacle 120, making the insertion and removal process smoother.

[0046] Alternatively, as Figure 1 and Figure 2 As shown, the groove wall of the first accommodating groove 121 is provided with at least one first annular groove, and the groove wall of the second accommodating groove 112 is provided with at least one second annular groove 126; when the head seat is plugged in, the first annular groove and the outer surface of the plug-in portion 111 form a first air storage chamber 131 for storing air; the second annular groove 126 and the outer surface of the adapter assembly 140 form a second air storage chamber 132 for storing air. In this embodiment, there is one first annular groove, which is located near the bottom of the first accommodating groove 121. In addition, a sealing groove 127 is provided at a position away from the bottom of the first accommodating groove 121, and a sealing ring 128 is installed in the sealing groove 127 to increase air tightness. At the same time, this embodiment is provided with two second annular grooves 126, which can form two second air storage chambers 132 when the head seat is plugged in to better store gas.

[0047] Furthermore, if Figure 4 and Figure 9As shown, the adapter assembly 140 includes a first cylindrical body 1401 and a second cylindrical body 1402 connected to each other. The first cylindrical body 1401 is arranged toward the bottom of the first accommodating groove 121. The first cylindrical body 1401 and the second cylindrical body 1402 are arranged coaxially, and the diameter of the first cylindrical body 1401 is smaller than that of the second cylindrical body 1402. When the head seat is inserted, one of the second annular grooves 126 is exactly oriented toward the first cylindrical body 1401. Through this arrangement, the second cylindrical body 1402 abuts against the first cylindrical body 1401, ensuring a tight connection. However, due to its smaller diameter, the first cylindrical body 1401 forms a gap with the groove wall of the second accommodating groove 112. This gap is connected to the second annular groove 126, which is equivalent to expanding the gas storage space of the second annular groove 126.

[0048] At least one third air storage chamber 133 is recessed inwardly on the outer surface of the adapter assembly 140, and the third air storage chamber 133 extends through the adapter assembly 140 along the axial direction of the adapter assembly 140. In this embodiment, the third air storage chamber 133 is disposed on the outer side of the second cylinder 1402, and extends through the second cylinder 1402 along the axial direction of the second cylinder 1402, connecting the two second air storage chambers 132. There are multiple third air storage chambers 133, and the multiple third air storage chambers 133 are spaced apart along the circumference of the second cylinder 1402. Specifically, in this embodiment, a total of four third air storage chambers 133 are provided, and a protrusion is formed between two adjacent third air storage chambers 133 to abut against the wall of the second accommodating groove 112. The third air storage chamber 133 can both expand the air storage space and connect the two second air storage chambers 132 to ensure the flow of gas.

[0049] In summary, an embodiment of the present invention provides an underwater detachable connector 100, comprising a plug 110, a socket 120, and an adapter assembly 140. A first receiving groove 121 is recessed on the side of the socket 120 facing the plug 110. The adapter assembly 140 is disposed within the first receiving groove 121 and is removably connected to the bottom of the first receiving groove 121. An annular slot 141 is formed between the outer side of the adapter assembly 140 and the wall of the first receiving groove 121. A ring-shaped plug-in portion 111 is protruded from the side of the plug 110 facing the socket 120, which is configured to engage with the annular slot 141. The plug-in portion 111 forms a second receiving groove 112. This staggered plug-in arrangement significantly enhances the tightness of the plug-in arrangement. Furthermore, the adapter assembly 140 utilizes a double-sided wire spring that engages with the pins on the plug 110 and the socket 120, respectively. This connection maintains effective electrical continuity between the plug 110 and the socket 120 even if the connection becomes loose over time, significantly increasing the reliability of the connection. The underwater detachable connector 100 has a novel structure, is easy to use, and has a longer service life.

[0050] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
