Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a connector and connector kit. Background Technology

[0002] Energy storage batteries are a crucial component of residential energy storage systems. Connectors are required when connecting batteries to inverters or multiple batteries. Batteries need to provide power, send status information, and receive control commands; therefore, hybrid signal-power connectors are often used for ease of connection. In battery stacking, the connector position is not visible. To accommodate tolerances, blind-mating connectors need to be able to float, thus requiring floating electrical connectors. Floating electrical connectors are those that can move or "float" relatively within a certain range during connection. Their design purpose is to compensate for installation errors between connected components, displacement caused by thermal expansion and contraction, and to ensure reliable connection under complex conditions such as vibration.

[0003] In related technologies, the floating end of a floating connector does not have waterproof performance on its own; it only has waterproof performance when the floating end and the fixed end are connected. Therefore, it cannot achieve both good waterproof performance and floating installation performance. Utility Model Content

One end of the first electrical connection part passes through the housing and is connected to the second electrical connection part, and the other end is connected to the second fixing part. The second fixing part abuts against the housing. The second fixing part is provided with a second annular groove. The first waterproof sealing ring is located in the second annular groove. One end of the first waterproof sealing ring abuts against the housing, and the other end abuts against the groove surface of the second annular groove.

[0018] In some embodiments, the first connector further includes a housing and a second waterproof sealing ring. The first electrical connection portion passes through the housing and is connected to the second electrical connection portion.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] The connector of this invention includes a first connecting seat, a second connecting seat, and a waterproof sleeve. The first connecting seat can serve as a floating end that can move relative to the second connecting seat during the docking process, and the second connecting seat can serve as the fixed end of the connector. The first connecting seat has a cavity and a first electrical connection part disposed within the cavity. One end of the second connecting seat has a second electrical connection part, which extends into the cavity and floats to connect with the first electrical connection part. Therefore, the mating position between the first and second electrical connection parts is located within the cavity. Based on the waterproofing requirements of the second connecting seat, the first waterproof part of the waterproof sleeve is fixedly connected to the first connecting seat, the second waterproof part is fitted around the outer periphery of the second connecting seat, and the third waterproof part covers the gap between the second electrical connection part and the opening. Thus, the waterproof sleeve can seal the gap formed by the floating connection of the first and second electrical connection parts.

[0049] In related technologies, the floating end of a floating connector does not have waterproof performance on its own; it only has waterproof performance when the floating end and the fixed end are connected. Therefore, it cannot achieve both good waterproof performance and floating installation performance.

[0050] In view of this, see Figures 1-11 In an embodiment of this utility model, a connector 100 is provided, which includes a first connector 110, a second connector 120, and a waterproof sleeve 130.

[0051] For details, see Figures 1-6 The first connector 110 has a cavity 111 and a first electrical connection portion 112 disposed within the cavity 111, with an opening 1111 at one end of the cavity 111. Correspondingly, the second connector 120 has a second electrical connection portion 121 at one end, which extends into the cavity 111 and is floatingly connected to the first electrical connection portion 112. The second connector 120 can serve as a floating end that can move relative to the first connector 110 during the docking process, and the first connector 110 can serve as a fixed end of the connector 100, or similarly, it can serve as a floating end that can move relative to the second connector 120 during the docking process. The following description uses the embodiment where the second connector 120 is the floating end and the first connector 110 is the fixed end. In addition, the first electrical connection part 112 and the second electrical connection part 121 are the parts of the first connector 110 and the second connector 120 used for electrical connection, respectively. According to the requirements, the first electrical connection part 112 and the second electrical connection part 121 can be electrically connected in any suitable manner.

[0052] According to the above configuration, the mating position between the first electrical connection 112 and the second electrical connection 121 is located within the cavity 111, while the portion of the opening 1111 protruding between the second electrical connection 121 and the cavity 111 provides a floating allowance for the second electrical connection 121, meaning the second electrical connection 121 can float and mate radially along the opening 1111. Based on the waterproofing requirements of the second connector 120, it is necessary to isolate the gap formed by the floating connection and the portion mating with the electrical connection. Therefore, see... Figures 1-6 as well as Figure 10 Special reference Figure 6 A waterproof sleeve 130 is disposed within the cavity 111 (it may be partially disposed within the cavity 111). The waterproof sleeve 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 connecting seat 110. The second waterproof portion 132 is sleeved on the outer periphery of the second connecting seat 120. The third waterproof portion 133 covers the gap between the second electrical connecting portion 121 and the opening 1111. It can be understood that through the combined action of the first waterproof portion 131, the second waterproof portion 132, and the third waterproof portion 133, the waterproof sleeve 130 can seal the gap formed by the floating connection (e.g., Figure 5 In the illustrated embodiment, the waterproof sleeve 130 prevents water around the sidewall of the first connector 110 from entering the cavity 111 through the opening 1111; it also prevents water around the contact point between the first connector 110 and the second connector 120 from entering the cavity 111 through the opening 1111. To enable the waterproof sleeve 130 to accommodate the floating connection between the second electrical connection 121 and the first electrical connection 112, the second waterproof part 132 is configured to move with the second electrical connection 121. Therefore, the material of the second waterproof part 132 is a soft material (e.g., rubber, silicone, etc.), and it can be that only the material of the second waterproof part 132 is soft, or the entire waterproof sleeve 130 can be made of soft material.

[0053] As can be seen, the connector 100 of this utility model includes a first connecting seat 110, a second connecting seat 120, and a waterproof sleeve 130. The first connecting seat 110 can serve as a floating end that can move relative to the second connecting seat 120 during the docking process, and the second connecting seat 120 can serve as a fixed end of the connector 100. The first connecting seat 110 has a cavity 111 and a first electrical connection portion 112 disposed in the cavity 111. One end of the second connecting seat 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. Therefore, the mating position between the first electrical connection portion 112 and the second electrical connection portion 121 is located in the cavity 111. According to the waterproof requirements of the second connecting seat 120, the first waterproof portion 131 of the waterproof sleeve 130 is fixedly connected to the first connecting seat 110, the second waterproof portion 132 is sleeved on the outer periphery of the second connecting seat 120, and the third waterproof portion 133 covers the gap between the second electrical connection portion 121 and the opening 1111. Therefore, the waterproof sleeve 130 can seal the gap formed by the floating connection between the first electrical connection 112 and the second electrical connection 121. Compared with related technologies that do not have a separate waterproof structure for the floating end, and whose waterproof performance is only achieved after the floating end and the fixed end are connected, the solution of this utility model enables the second connector 120, which serves as the floating end, to have waterproof performance, thus achieving both waterproof effect and floating installation effect. Therefore, the connector 100 of this utility model enables the floating end itself to have better waterproof performance.

[0054] For specific floating connection types, see [link / reference]. Figures 6-8 In some embodiments, the first connecting seat 110 includes a first connecting member 113, and the second connecting seat 120 has a first mounting hole 122. Along a direction perpendicular to the axis of the first mounting hole 122, the maximum size of the first mounting hole 122 is larger than the maximum size of the first connecting member 113. The first connecting member 113 passes through the first mounting hole 122, allowing the second electrical connection portion 121 to float with the first electrical connection portion 112. It is understood that, based on the design that the size of the first mounting hole 122 is larger than the size of the first connecting member 113, the first connecting member 113 can move within the first mounting hole 122, thereby allowing the second connecting seat 120 to move relative to the first connecting seat 110, and achieving electrical connection with the first electrical connection portion 112 within the range of movement. The size difference between the first mounting hole 122 and the first connecting member 113 corresponds to the floating displacement margin of the second connecting seat 120. This value can be set according to requirements; for example, in some embodiments, the second connecting seat 120 can float 2mm on one side.

[0055] It should be noted that the through-hole described in this utility model can be a complete through-hole or a partial through-hole. For example, the first connector 113 can be completely through the first mounting hole 122 or located inside the first mounting hole 122.

[0056] Based on the second connector 120 defined in the above embodiments, see [reference] Figures 1-5 In some embodiments, the first connecting seat 110 further includes a housing 114 and a first fixing part 115. The second connecting seat 120 passes through the housing 114 and the first fixing part 115. Along the axial direction of the opening 1111, the first fixing part 115 abuts against the side of the second connecting seat 120 near the first connecting seat 110. The housing 114 is sleeved on the outer periphery of the first electrical connecting part 112 and the second electrical connecting part 121. The housing 114 and the first fixing part 115 abut against the two sides of the first waterproof part 131, respectively. It can be understood that, on the one hand, the housing 114 can protect the first electrical connecting part 112 and the second electrical connecting part 121, and the first fixing part 115 can limit the axial displacement of the second connecting seat 120. On the other hand, through the above-mentioned abutment arrangement, the first waterproof part 131 can be fixed, so that the position of the waterproof sleeve 130 is more stable and the waterproof performance is better. During the movement of the second connecting seat 120, the first waterproof part 131 can remain stationary relative to the second connecting seat 120.

[0057] The outer casing 114 defined in the above embodiments, in order to achieve a better sealing effect for the waterproof sleeve 130, see [reference needed]. Figure 5 In some embodiments, the inner periphery of the first fixing portion 115 and the outer periphery of the second connecting seat 120 together 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 connecting seat 120 within the first fixing portion 115. By extending the third waterproof portion 133 into the annular cavity 140, the waterproof sleeve 130 can be fixed within the annular cavity 140, limiting the radial displacement of the waterproof sleeve 130, thereby improving the waterproof performance of the waterproof sleeve 130.

[0058] To more stably fix the waterproof sleeve 130 in the axial direction, a first mounting hole 122 is provided in the second connecting seat 120 based on the above embodiment, see [reference]. Figures 7-8In some embodiments, the first waterproof part 131 has a second mounting hole 134, and the first connecting seat 110 has a third mounting hole 1141. The first connecting member 113 of the first connecting seat 110 passes through the first mounting hole 122, the second mounting hole 134, and the third mounting hole 1141 to thread-connect the second connecting seat 120, the first waterproof part 131, and the outer shell 114. More specifically, the outer shell 114 and the first fixing part 115 of the first connecting seat 110 may both be provided with the third mounting hole 1141. The first connecting member 113 includes a screw and a nut. The screw passes through the second connecting seat 120, the first fixing part 115, the first waterproof part 131, and the outer shell 114 in sequence. The nut is disposed inside the outer shell 114 and connects to one end of the screw that protrudes from the outer shell 114, thereby forming the aforementioned threaded connection. In some embodiments, the first connecting member 113 may include multiple different connecting members, which respectively pass through the first mounting hole 122, the second mounting hole 134, and the third mounting hole 1141 to form a bolted connection.

[0059] Corresponding to the floating connection between the first electrical connection 112 and the second electrical connection 121, in order to improve the waterproof performance of the waterproof sleeve 130, see [reference needed]. 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 connecting seat 110 relative to the second connecting seat 120. According to the above requirements, the materials of the second waterproof part 132 and the third waterproof part 133 can both be soft materials such as rubber or silicone. It is understood that since the second waterproof part 132 is sleeved on the outer periphery of the second connecting seat 120, and the third waterproof part 133 is connected to the second waterproof part 132 and located within the floating space (annular cavity 140) of the second connecting seat 120 within the first fixing part 115, the second waterproof part 132 and the third waterproof part 133 can move together with the second connecting seat 120 during the movement of the first connecting seat 110 relative to the second connecting seat 120, thereby ensuring waterproof performance. At this time, the first waterproof part 131 can remain stationary relative to the second connecting seat 120, thus fixing the overall position of the waterproof sleeve 130.

[0060] To further secure the axial position of the waterproof sleeve 130, see [link / reference]. Figure 5In some embodiments, the first connecting seat 110 further includes a first mating portion 119, and the second connecting seat 120 further includes a second mating portion 123. Both the first mating portion 119 and the second mating portion 123 extend radially along the opening 1111. The waterproof sleeve 130 further includes a third mating portion 135, which connects the second waterproof portion 132 and the third waterproof portion 133. One side of the third mating portion 135 abuts against the first mating portion 119, and the other side abuts against the second mating portion 123. It can be understood that the third mating portion 135 can serve as a transition portion between the second waterproof portion 132 and the third waterproof portion 133. The abutments of the first mating portion 119 and the second mating portion 123 against the two sides of the third mating portion 135 can further fix the position of the waterproof sleeve 130 along the axis of the opening 1111, thereby improving the waterproof performance of the waterproof sleeve 130.

[0061] Furthermore, for the specific form of the second waterproof part 132 being fitted onto the second connecting seat 120, please refer to... Figure 5 In some embodiments, the second connecting seat 120 has a first annular groove 124, and the second waterproof part 132 is sleeved in the first annular groove 124. The first annular groove 124 allows the second waterproof part 132 to cooperate with the second connecting seat 120, which helps to fix the axial position of the waterproof sleeve 130, thereby improving the waterproof performance of the waterproof sleeve 130.

[0062] In addition to using a waterproof sleeve 130 to improve the waterproof performance of the second connector 120, other waterproof structures can be provided for the first connector 110. For details, see [link to relevant documentation]. Figure 9 In some embodiments, the first connecting seat 110 further includes a second fixing part 116 and a first waterproof sealing ring 117. One end of the first electrical connection part 112 passes through the outer shell 114 and connects to the second electrical connection part 121, and the other end connects to the second fixing part 116. It is understood that while the first electrical connection part 112 passes through the outer shell 114 and connects to the second electrical connection part 121, the second fixing part 116 abuts against the outer shell 114 to limit the axial displacement of the first connecting seat 110, or further to fix the first connecting seat 110. Based on this, in order to seal the area where the second fixing part 116 abuts against the outer shell 114, in some embodiments, the second fixing part 116 is provided with a second annular groove 1161, and the first waterproof sealing ring 117 is located in the second annular groove 1161. One end of the first waterproof sealing ring 117 abuts against the outer shell 114, and the other end abuts against the groove surface of the second annular groove 1161. The provision of the first waterproof sealing ring 117 ensures the waterproof performance of the first connecting seat 110 alone.

[0063] Additionally, see Figure 9 and Figure 11In some embodiments, the first connecting seat 110 further includes a second waterproof sealing ring 118, and the first electrical connection portion 112 is provided with a third annular groove 1121. The second waterproof sealing ring 118 is located in the third annular groove 1121, with one end of the second waterproof sealing ring 118 abutting against the second connecting seat 120 and the other end abutting against the groove surface of the third annular groove 1121. The provision of the second waterproof sealing ring 118 ensures the waterproof performance of the first connecting seat 110 and the second connecting seat 120 after they are connected.

[0064] In addition, see Figure 9 and Figure 11 In some embodiments, the first electrical connection portion 112 includes a first pin 1122 and a third waterproof sealing ring 1123, the third waterproof sealing ring 1123 being sleeved on the outer periphery of the first pin 1122. The first pin 1122 is a lead for electrical connection of the first electrical connection portion 112. Depending on the requirements, the first pin 1122 can be any suitable type of pin, such as a power pin, which can transmit higher power electrical energy to provide sufficient operating power support for connected devices or circuit modules. The third waterproof sealing ring 1123 increases the waterproof performance of the electrical connection of the first pin 1122. To further enhance waterproof performance, the first pin 1122 can be provided with a sealing ring groove that fits the third waterproof sealing ring 1123, so that the third waterproof sealing ring 1123 is sleeved within the sealing ring groove. For the second electrical connection portion 121, a similar sealing structure can also be provided, that is, the second electrical connection portion 121 includes a second pin 1211 and a fourth waterproof sealing ring 1212, the fourth waterproof sealing ring 1212 being sleeved on the outer periphery of the second pin 1211. 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 in the above embodiment, and will not be repeated here. In some embodiments, the connector 100 also includes signal pins respectively connected to the first connector 110 and the second connector 120. The signal pins can use waterproof sealing rings similar to those of the first pin 1122 and the second pin 1211 to ensure waterproof performance. The signal pins are pins in the electrical connector 100 specifically used for transmitting electrical signals. Their core function is to realize information interaction between various electronic devices and circuit modules, accurately transmitting control signals, data signals, etc., between different components to ensure the coordinated and orderly operation of the entire electronic system.

[0065] Based on the waterproof structural designs of the above embodiments, firstly, the waterproof sleeve 130 can ensure the waterproof performance around the gap formed by the floating connection of the second connector 120; secondly, the fourth waterproof sealing ring 1212 can ensure the waterproof performance at the second pin 1211 of the second connector 120; thirdly, the first waterproof sealing ring 117 can ensure the waterproof performance at the outer periphery of the first connector 110; fourthly, the third waterproof sealing ring 1123 can ensure the waterproof performance at the first pin 1122 of the first connector 110; and fifthly, the second waterproof sealing ring 118 can ensure the waterproof performance after the first connector 110 and the second connector 120 are connected. Through these five waterproof structural designs, the connector 100 can have strong waterproof performance whether it is in a connected or disconnected state.
