[0044] Example 1

[0045] Figure 1 and Figure 2The exploded view and structural view of the connector meeting the high pressure and anti-condensation requirements of this embodiment are respectively given. Figure 1 and Figure 2 As shown, this embodiment provides a connector that meets high voltage and anti-condensation requirements. The connector that meets high voltage and anti-condensation requirements includes a male plug 1 and a female plug 2. The male plug 1 and the female plug 2 are plugged together to connect the cable 3 to the board.

[0046] Specifically, Figure 3 and Figure 4 The structural diagrams of the two ends of the male plug 1 are given respectively. Figures 1 to 4 , the male plug 1 is connected to the flat cable 3, and one end of the flat cable 3 is provided with a plurality of contact pieces 31. At the same time, one end of the male plug 1 is a first plug end 110 for connecting with the female plug 2. After the male plug 1 is connected to the flat cable 3, the contact piece 31 is close to the first plug end 110. The first plug end 110 is provided with a plurality of plug male parts 111, and a fence 112 is provided between adjacent plug male parts 111. Different contact pieces 31 are located at different plug male parts 111, and adjacent contact pieces 31 are separated by the fence 112, thereby increasing the creepage distance of the gold finger, thereby meeting the application requirements of high voltage.

[0047] Figure 5 and Figure 6 The structural diagrams of the two ends of the female plug 2 are given respectively. Figure 5 and Figure 6 , the female plug 2 is used to connect with the pad and the circuit board. The female plug 2 includes a female plug body 211 and a plurality of terminals 212 extending along the two ends of the female plug body 211. One end of the female plug 2 is a second plug end 210, which can be used to connect with the first plug end 110. Specifically, the second plug end 210 includes a plurality of snap-fit ​​seats 213. One end of the terminal 212 is a connection end, which is connected to the snap-fit ​​seat 213 and is used to connect with the contact 31 on the flat cable 3. At the second plug end 210, the terminal 212 and the snap-fit ​​seat 213 form a plug-in female part 214. The snap-fit ​​seat 213 is a protrusion from the female plug body 211 toward the second plug end 210. In this embodiment, the connection end of the terminal 212 is located below the snap-fit ​​seat 213, and at the same time, a space is formed below the snap-fit ​​seat 213 to facilitate the plug-in connection of the contact 31 of the flat cable 3. The plug-in female part 214 is adapted to the plug-in male part 111.

[0048] The other end of the female plug body 211 is a welding end 220, and one end of the terminal 212 at the welding end 220 is a welding foot for connecting with a pad and a circuit board. The female plug body 211 is provided with a plurality of baffles 221 at the welding end 220, and the baffles 221 and the terminals 212 are arranged alternately, and the baffles 221 increase the creepage distance of the adjacent terminals at the welding end 220, further improving the high voltage resistance performance.

[0049] Figure 7The schematic diagram of the structure at the welding end after the female plug is connected to the pad is given. Figure 8 and Fig. 9 The cross-sectional views of the connector of this embodiment that meets the requirements of high pressure and anti-condensation at different angles when in use are respectively given. Figure 8 This is a cross-sectional view of a connector that meets high pressure and anti-condensation requirements along the AA section plane. Fig. 9 This is a cross-sectional view of the BB section of the connector that meets high pressure and anti-condensation requirements. Figure 2 , Figure 7 , Figure 8 and Fig. 9 , move the male plug 1 toward the female plug 2, and the snap-fit ​​seat 213 is inserted into the male plug part 111 and snap-fitted to connect, so that the terminal 212 of the female plug 2 is connected with the contact 31 of the male plug 1. It should be noted that after the connection is completed, a plug-in cavity 217 is formed between the snap-fit ​​seat 213 and the partition 112, and the contact point formed by the connection between the terminal 212 and the contact 31 is located in the plug-in cavity 217. The contact point is separated by the snap-fit ​​seat 213 and the partition 112 and is independent of each other. Therefore, when condensed water appears in the connector that meets the high voltage and anti-condensation requirements, the condensed water cannot connect to adjacent contacts under the action of the snap-fit ​​seat 213 and the partition 112, thereby greatly reducing the risk of circuit short circuit or leakage caused by condensed water, and increasing the service life and safety of the connector that meets the high voltage and anti-condensation requirements. Similarly, at the welding end 220 of the female plug 2, the baffle 221 also increases the creepage distance and breakdown distance between adjacent terminals 212, thereby meeting the high voltage requirements and improving the performance of the connector that meets high voltage and anti-condensation requirements.

[0050] It should be noted that, in order to increase the stability of the male plug 1 and the female plug 2 after being plugged in, the connector that meets the requirements of high voltage and anti-condensation in this embodiment further includes a lock 5 and a locking member 6. Among them, the lock 5 and the locking member 6 are arranged on the male plug 1, and the male plug 1 is further fixedly connected to the female plug 2 through the lock 5 and the locking member 6 to prevent the male plug 1 from easily falling off the female plug 2. The lock 5 and the locking member 6 can be a secondary locking structure. For example, in this embodiment, the locking member 6 is a CPA. It can be understood that this is not the only limitation on the locking structure of the male plug 1 and the female plug 2.

[0051] In summary, this embodiment provides a connector that meets the requirements of high voltage and anti-condensation. The connector that meets the requirements of high voltage and anti-condensation realizes the connection between the flat cable 3 and the circuit board through the plug-in connection of the male plug 1 and the female plug 2. The installation method is simple. At the same time, the independently connected terminals 212 and contacts 31 have the functions of anti-condensation and meeting high voltage requirements.

[0052] Example 2

[0053] See also Figures 1 to 9The connector that meets high pressure and anti-condensation requirements of this embodiment is the same as the connector that meets high pressure and anti-condensation requirements in Embodiment 1 as a whole, and is further optimized on the basis of Embodiment 1. The similarities between this embodiment and Embodiment 1 refer to Embodiment 1, and the improvements are further described below.

[0054] See also Fig. 9 In order to further increase the performance of the connector that meets high voltage and anti-condensation requirements, the length of the fence 112 is greater than or equal to the length of the contact piece 31, further increasing the path distance between adjacent contact pieces 31 and improving the anti-condensation function.

[0055] In addition, see Figure 3 , Figure 5 and Figure 8 , the male plug 1 is also provided with a rib 113 between adjacent male plug parts 111, and the female plug 2 is provided with a groove 215 matched with the rib 113 between adjacent female plug parts 214. When the female plug 2 and the male plug 1 are buckled and connected, the rib 113 is limited to the groove 215, further increasing the creepage distance between adjacent terminals 212. The male plug 1 is also provided with a bottom surface 114 connected to the first plug end 110. In this embodiment, the rib 113 extends from the first plug end 110 to the bottom surface 114 of the male plug 1, and the rib 113 is integrally formed with the barrier 112. Of course, this is not the only limitation on the structure of the rib 113 and the barrier 112. In some embodiments, the rib 113 may not extend to the bottom surface 114 of the male plug 1, or the rib 113 may be separated from the barrier 112.

[0057] See also Figures 1 to 9 The connector that meets high pressure and anti-condensation requirements in this embodiment is the same as the connector that meets high pressure and anti-condensation requirements in Embodiment 1, and is further optimized on the basis of Embodiment 1 and Embodiment 2. Please refer to Embodiment 1 and Embodiment 2 for the similarities, and the improvements are further described below.

Furthermore, a plurality of avoidance holes 41 are provided on the soldering pad 4, and the avoidance holes 41 and the terminals 212 are arranged alternately. In this embodiment, the baffle 221 is limited in the middle of the avoidance holes 41. The provision of the avoidance holes 41 can increase the creepage distance of the adjacent terminals 212 at the soldering pad 4. In order to further meet the requirements of high voltage, the length of the avoidance holes 41 is preferably greater than the length of the baffle 221, so as to further increase the creepage distance of the adjacent terminals 212 and improve the performance of the connector that meets the requirements of high voltage and condensation prevention.

[0060] See also Figures 1 to 10 The connector that meets high pressure and anti-condensation requirements of this embodiment is the same as the connector that meets high pressure and anti-condensation requirements in Embodiment 1, and is further optimized on the basis of Embodiment 1, Embodiment 2 and Embodiment 3. For the similarities, please refer to Embodiment 1, Embodiment 2 and Embodiment 3. The improvements are further described below.

[0062] In addition, in order to facilitate the connection between the flat cable 3 and the male plug 1, the other end of the male plug 1 opposite to the first plug end 110 is an insertion end 120, and a guide structure is provided between the insertion end 120 and the flat cable 3. Specifically, the male plug 1 is provided with a guide portion 121 extending from the insertion end 120 toward the first plug end 110, and the flat cable 3 is provided with a guide groove 32 adapted to the guide portion 121. During installation, the guide groove 32 is inserted into the male plug 1 along the guide portion 121, and the contact pieces 31 are separated at different male plug parts 111. In this embodiment, the guide groove 32 is provided between adjacent contact pieces 31, and the guide portion 121 is integrally connected with the partition 112, so that the contact pieces 31 are separated at the same time during the installation of the flat cable 3 and the male plug 1. It can be understood that in some embodiments, the guide portion 121 can also be provided separately from the partition 112.

[0063] The above contents are merely examples and illustrations of the structure of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model.
