[0025] In the related art, the floating end of the floating docking connector does not have waterproof performance alone, and has waterproof performance only when the floating end and the fixed end are docked, thereby failing to achieve both good waterproof effect and floating installation effect.

[0026] In view of this, see Figure 1-Figure 11 In an embodiment of the present invention, a connector 100 is provided. The connector 100 includes a first connection seat 110, a second connection seat 120 and a waterproof cover 130.

[0027] For details, see Figure 1-Figure 6 The first connection base 110 has a cavity 111 and a first electrical connection portion 112 disposed in the cavity 111, and one end of the cavity 111 is provided with an opening 1111. Correspondingly, one end of the second connection base 120 is provided with a second electrical connection portion 121, which extends into the cavity 111 and is floatingly connected to the first electrical connection portion 112. The second connection base 120 can be used as a floating end that can move relative to the first connection base 110 during the docking process, and the first connection base 110 can be used as a fixed end of the connector 100 or the first connection base 110 can also be used as a floating end that can move relative to the second connection base 120 during the docking process. The following embodiments are described in which the second connection seat 120 is a floating end and the first connection seat 110 is a fixed end. In addition, the first electrical connection portion 112 and the second electrical connection portion 121 are respectively the parts of the first connection seat 110 and the second connection seat 120 used for electrical connection. According to requirements, the first electrical connection portion 112 and the second electrical connection portion 121 can be electrically connected in any suitable manner.

[0028] According to the above configuration, the mating position between the first electrical connection part 112 and the second electrical connection part 121 is located in the concave cavity 111, and a portion of the opening 1111 leaking between the second electrical connection part 121 and the concave cavity 111 can provide a floating margin for the second electrical connection part 121, that is, the second electrical connection part 121 can float and dock along the radial direction of the opening 1111. According to the waterproof requirement of the second connection seat 120, it is necessary to isolate the gap formed by the floating connection and the portion mating with the electrical connection. Therefore, see Figure 1-Figure 6 as well as Fig.10 , with particular reference to Figure 6The waterproof cover 130 is disposed in the concave cavity 111 (may be partially disposed in the concave cavity 111), and the waterproof cover 130 includes a first waterproof portion 131, a second waterproof portion 132, and a third waterproof portion 133 connected to each other. The first waterproof portion 131 is fixedly connected to the first connection seat 110, the second waterproof portion 132 is sleeved on the outer periphery of the second connection seat 120, and the third waterproof portion 133 covers the gap between the second electrical connection portion 121 and the opening 1111. It can be understood that through the joint action of the first waterproof portion 131, the second waterproof portion 132, and the third waterproof portion 133, the waterproof cover 130 can block the gap formed by the floating connection (for example Figure 5 In the illustrated embodiment, the waterproof cover 130 can prevent water around the side wall of the first connection seat 110 from entering the concave cavity 111 through the opening 1111; it can also prevent water around the position where the first connection seat 110 and the second connection seat 120 abut against each other from entering the concave cavity 111 through the opening 1111). In order to enable the waterproof cover 130 to adapt to the floating connection between the second electrical connection part 121 and the first electrical connection part 112, the second waterproof part 132 is configured to move together with the second electrical connection part 121, so that the material of the second waterproof part 132 is a soft material (such as rubber, silicone, etc.), and only the material of the second waterproof part 132 can be a soft material, or the material of the entire waterproof cover 130 can be a soft material.

[0029] It can be seen that the connector 100 of the present invention includes a first connection seat 110, a second connection seat 120 and a waterproof cover 130. The first connection seat 110 can be used as a floating end that can move relative to the second connection seat 120 during the docking process, and the second connection seat 120 can be used as a fixed end of the connector 100. The first connection seat 110 has a concave cavity 111 and a first electrical connection portion 112 disposed in the concave cavity 111. One end of the second connection seat 120 is provided with a second electrical connection portion 121, which extends into the concave cavity 111 and is floatingly connected to the first electrical connection portion 112. Therefore, the mating position between the first electrical connection portion 112 and the second electrical connection portion 121 is located in the concave cavity 111. According to the waterproof requirement of the second connection seat 120, the first waterproof portion 131 of the waterproof cover 130 is fixedly connected to the first connection seat 110, the second waterproof portion 132 is sleeved on the outer periphery of the second connection seat 120, and the third waterproof portion 133 covers the gap between the second electrical connection portion 121 and the opening 1111. Thus, the waterproof cover 130 can block the gap formed by the floating connection between the first electrical connection part 112 and the second electrical connection part 121. Compared with the related art that does not have a separate waterproof structure for the floating end, and has waterproof performance only when the floating end and the fixed end are connected, the solution of the present invention can make the second connection seat 120 as the floating end have waterproof performance, taking into account both the waterproof effect and the floating installation effect. Therefore, the connector 100 of the present invention can make the floating end itself have better waterproof performance.

[0030] For specific floating connection forms, see Figure 6-Figure 8 In some embodiments, the first connection seat 110 includes a first connection member 113, and the second connection seat 120 has a first mounting hole 122. In the direction perpendicular to the axis of the first mounting hole 122, the maximum size of the first mounting hole 122 is greater than the maximum size of the first connection member 113. The first connection member 113 is inserted into the first mounting hole 122 so that the second electrical connection portion 121 is connected to the first electrical connection portion 112 in a floating manner. It can be understood that according to the design that the size of the first mounting hole 122 is greater than the size of the first connection member 113, the first connection member 113 can be moved in the first mounting hole 122, so that the second connection seat 120 can move relative to the first connection seat 110, and can achieve electrical connection with the first electrical connection portion 112 within the above range of movement. The size difference between the first mounting hole 122 and the first connection member 113 corresponds to the floating displacement margin of the second connection seat 120, and the value can be set according to the needs. For example, in some embodiments, the second connection seat 120 can float 2mm on one side.

[0031] It should be noted that the penetration described in the present invention may be a full penetration or a partial penetration. For example, one end of the first connecting member 113 passing through the first mounting hole 122 may completely penetrate the first mounting hole 122 or be located inside the first mounting hole 122.

[0032] Based on the second connection socket 120 defined in the above embodiment, see Figure 1-Figure 5 In some embodiments, the first connection seat 110 further includes a housing 114 and a first fixing portion 115, the second connection seat 120 is inserted through the housing 114 and the first fixing portion 115, along the axial direction of the opening 1111, the first fixing portion 115 abuts against a side of the second connection seat 120 close to the first connection seat 110, the housing 114 is sleeved on the outer periphery of the first electrical connection portion 112 and the second electrical connection portion 121, and the housing 114 and the first fixing portion 115 abut against two sides of the first waterproof portion 131 respectively. It can be understood that, on the one hand, the housing 114 can protect the first electrical connection portion 112 and the second electrical connection portion 121, and the first fixing portion 115 can limit the axial displacement of the second connection seat 120; on the other hand, through the above-mentioned abutment setting, it can be used to fix the first waterproof portion 131, so that the position of the waterproof cover 130 is more stable and the waterproof performance is better, and during the movement of the second connection seat 120, the first waterproof portion 131 can be stationary relative to the second connection seat 120.

[0033] In order to make the waterproof cover 130 have a better sealing effect, the housing 114 defined in the above embodiment is Figure 5In some embodiments, the inner periphery of the first fixing portion 115 and the outer periphery of the second connection seat 120 jointly form an annular cavity 140, and the third waterproof portion 133 extends into the annular cavity 140 along the axial direction of the opening 1111. A portion of the annular cavity 140 corresponds to the floating space of the second connection seat 120 in the first fixing portion 115. By extending the third waterproof portion 133 into the annular cavity 140, the annular cavity 140 can be used to fix the waterproof cover 130, limit the radial displacement of the waterproof cover 130, and thus help improve the waterproof performance of the waterproof cover 130.

[0034] In order to more stably fix the position of the waterproof cover 130 along the axial direction, the first mounting hole 122 is provided on the second connecting seat 120 according to the above embodiment. Figure 7-Figure 8 In some embodiments, the first waterproof part 131 has a second mounting hole 134, the first connection seat 110 has a third mounting hole 1141, and the first connector 113 of the first connection seat 110 is penetrated through the first mounting hole 122, the second mounting hole 134 and the third mounting hole 1141 to thread the seat body, the waterproof structure and the housing 114. More specifically, the housing 114 and the first fixing part 115 of the first connection seat 110 can both be provided with the third mounting hole 1141, and the first connector 113 includes a screw and a nut, the screw passes through the second connection seat 120, the first fixing part 115, the first waterproof part 131 and the housing 114 in sequence, and the nut is disposed in the housing 114 and connected to one end of the screw passing through the housing 114, thereby forming the above-mentioned threaded connection. In some embodiments, the first connector 113 may include a plurality of different connectors, and the first mounting hole 122, the second mounting hole 134 and the third mounting hole 1141 are respectively penetrated to form a bolt connection.

[0035] Corresponding to the floating connection between the first electrical connection portion 112 and the second electrical connection portion 121, in order to make the waterproof performance of the waterproof cover 130 better, see Figure 5 In some embodiments, the second waterproof part 132 and the third waterproof part 133 are configured to deform during the movement of the first connection seat 110 relative to the second connection seat 120. According to the above requirements, the materials of the second waterproof part 132 and the third waterproof part 133 can be soft materials such as rubber and silicone. It can be understood that since the second waterproof part 132 is sleeved on the outer periphery of the second connection seat 120, the third waterproof part 133 is connected to the second waterproof part 132 and is located in the floating space (annular cavity 140) of the second connection seat 120 in the first fixing part 115, the second waterproof part 132 and the third waterproof part 133 can move together with the second connection seat 120 during the movement of the first connection seat 110 relative to the second connection seat 120, thereby ensuring the waterproof performance. At this time, the first waterproof part 131 can be stationary relative to the second connection seat 120, so that the overall position of the waterproof cover 130 is fixed.

[0036] In order to further fix the position of the waterproof cover 130 along the axial direction, see Figure 5 In some embodiments, the first connection seat 110 further includes a first matching portion 119, the second connection seat 120 further includes a second matching portion 123, the first matching portion 119 and the second matching portion 123 both extend along the radial direction of the opening 1111, and the waterproof cover 130 further includes a third matching portion 135, the third matching portion 135 is connected between the second waterproof portion 132 and the third waterproof portion 133, one side of the third matching portion 135 abuts the first matching portion 119, and the other side abuts the second matching portion 123. It can be understood that the third matching portion 135 can serve as a transition portion between the second waterproof portion 132 and the third waterproof portion 133, and the first matching portion 119 and the second matching portion 123 respectively abut the two sides of the third matching portion 135, which can further fix the position of the waterproof cover 130 along the axis of the opening 1111, thereby facilitating the improvement of the waterproof performance of the waterproof cover 130.

[0037] In addition, for the specific form of the second waterproof portion 132 being sleeved on the second connecting seat 120, see Figure 5 In some embodiments, the second connection seat 120 has a first annular groove 124, and the second waterproof portion 132 is sleeved in the first annular groove 124. The first annular groove 124 is used to make the second waterproof portion 132 cooperate with the second connection seat 120, which is beneficial to fix the axial position of the waterproof cover 130, thereby improving the waterproof performance of the waterproof cover 130.

[0038] In addition to using the waterproof cover 130 to improve the waterproof performance of the second connection base 120, other waterproof structures can also be provided on the first connection base 110. Fig. 9 In some embodiments, the first connection seat 110 further includes a second fixing portion 116 and a first waterproof sealing ring 117. One end of the first electrical connection portion 112 is inserted through the housing 114 and connected to the second electrical connection portion 121, and the other end is connected to the second fixing portion 116. It can be understood that while the first electrical connection portion 112 is used to be inserted through the housing 114 and connected to the second electrical connection portion 121, the second fixing portion 116 abuts against the housing 114 to limit the displacement of the first connection seat 110 in the axial direction, or further plays a role in fixing the first connection seat 110. Based on this, in order to seal the part where the second fixing portion 116 abuts against the housing 114, in some embodiments, the second fixing portion 116 is provided with a second annular groove 1161, and the first waterproof sealing ring 117 is located in the second annular groove 1161, and one end of the first waterproof sealing ring 117 abuts against the housing 114, and the other end abuts against the groove surface of the second annular groove 1161. By setting the first waterproof sealing ring 117, the independent waterproof performance of the first connection seat 110 can be guaranteed.

[0039] Also, see Fig. 9 and Fig.11 In some embodiments, the first connection seat 110 further includes a second waterproof seal ring 118, the first electrical connection portion 112 is provided with a third annular groove 1121, the second waterproof seal ring 118 is located in the third annular groove 1121, one end of the second waterproof seal ring 118 abuts against the second connection seat 120, and the other end abuts against the groove surface of the third annular groove 1121. By providing the second waterproof seal ring 118, after the first connection seat 110 and the second connection seat 120 are connected, the waterproof performance of the two can be guaranteed after the two are connected.

[0040] In addition, see Fig. 9 and Fig.11 In some embodiments, the first electrical connection portion 112 includes a first pin 1122 and a third waterproof sealing ring 1123, and the third waterproof sealing ring 1123 is sleeved on the outer periphery of the first pin 1122. The first pin 1122 is a pin of the first electrical connection portion 112 for electrical connection. According to requirements, the first pin 1122 can be any suitable type of pin, for example, the first pin 1122 can be a power pin, which can be responsible for transmitting relatively high power electrical energy, aiming to provide sufficient working power support for the device or circuit module connected thereto. The provision of the third waterproof sealing ring 1123 can increase the waterproof performance of the electrical connection of the first pin 1122. In order to further increase the waterproof performance, the first pin 1122 can be provided with a sealing ring groove adapted to the third waterproof sealing ring 1123, so that the third waterproof sealing ring 1123 is sleeved in the sealing ring groove. For the second electrical connection part 121, a similar sealing structure can also be provided, that is, the second electrical connection part 121 includes a second pin 1211 and a fourth waterproof sealing ring 1212, and the fourth waterproof sealing ring 1212 is sleeved on the outer periphery of the second pin 1211. Among them, the arrangement of the second pin 1211 and the fourth waterproof sealing ring 1212 can refer to the first pin 1122 and the third waterproof sealing ring 1123 of the above-mentioned embodiment, and will not be repeated here. In some embodiments, the connector 100 also includes a signal pin connected to the first connection seat 110 and the second connection seat 120 respectively, and the signal pin can use a waterproof sealing ring similar to the first pin 1122 and the second pin 1211 to ensure waterproof performance. The signal pin is a pin in the electrical connector 100 specifically used for transmitting electrical signals.
