When the existing wiring harness is connected to the pin in the male socket or the female socket in the waterproof electrical connector, the wiring harness and the pin are usually connected by tinning. However, during the manual or automatic metal pin soldering process, since the interval between the pins is small, it is easy for two adjacent pins to stick to each other during the soldering process, which will cause the waterproof electrical connector to short-circuit in actual product applications.

[0039] The utility model provides a waterproof electric connector which is used for equipment such as water purifiers.

[0041] The first mounting seat 110 is provided with at least two first plug holes 111, wherein the first mounting seat 110 is provided with a waterproof ring 160 on its outer sleeve, wherein the first mounting seat 110 may be a columnar structure, and for the columnar structure, the first mounting seat 110 may be configured as a cylinder, a prism, or other columnar structures. In other embodiments, the first mounting seat 110 may also be configured as a truncated cone structure. In this embodiment, the specific structure of the first mounting seat 110 is not limited.

[0042] The first isolation seat 120 is fixed to the first mounting seat 110 and is provided with at least two first isolation positions 121, and the first isolation positions 121 are arranged one-to-one with the first plug holes 111; at least two first conductive pins 130 are fixed to the first plug holes 111 one-to-one, and at most one end of the first conductive pin 130 is located outside the first isolation position 121, and the first isolation seat 120 is used to separate the ends of two adjacent first conductive pins 130; in this embodiment, when the first conductive pins 130, the first plug holes 111 and the first When the number of isolation positions 121 is two, the two first conductive needles 130 are fixedly arranged in the first plug hole 111 in a one-to-one correspondence, and at most one end of one first conductive needle 130 is located outside the first isolation position 121, that is, one end of another first conductive needle 130 is located in the first isolation position 121. At this time, the ends of the two first conductive needles 130 can be separated by the action of the two first isolation positions 121. At this time, during the soldering process, the occurrence of tin sticking between the two first conductive needles 130 can be avoided, thereby solving the technical problems existing in the prior art.

[0043] Meanwhile, in the present embodiment, the number of the first conductive pins 130 may be three, four, five, six, etc., and no limitation is made here. The number of the first plug holes 111 and the first isolation positions 121 provided corresponding to the number of the first conductive pins 130 may also be three, four, five, six, etc. Meanwhile, in the present embodiment, there may be a situation where the number of the first plug holes 111 is three, the number of the first isolation positions 121 is two, and the number of the first conductive pins 130 is two, and there may be a situation where the number of the first plug holes 111 is three, the number of the first isolation positions 121 is three, and the number of the first conductive pins 130 is two, that is, the number of the first plug holes 111 and the number of the first isolation positions 121 do not correspond to the number of the first conductive pins 130.

[0044] The technical solution of the present invention is to set a first isolation seat 120 on the first mounting seat 110, and a first isolation position 121 is set in the first isolation seat 120. When two first conductive needles 130 are installed in the first mounting seat 110, at most one end of one first conductive needle 130 is located outside the first isolation position 121, that is, the remaining first conductive needles 130 are all located in the first isolation position 121 in a one-to-one correspondence. At this time, under the action of the first isolation position 121, the ends of two adjacent first conductive needles 130 can be separated. At this time, when the ends of the first conductive needles 130 are connected to the wiring harness by soldering, tin sticking can be avoided, thereby solving the technical problems existing in the prior art.

[0045] In one embodiment, reference Figure 1 , Figure 2 , Figure 3 , the second connection part 200 may adopt the following structure, wherein the second connection part 200 comprises: a second mounting seat 210, a second isolation seat 220 and at least two second conductive needles 230;

The second conductive pins 230 are fixed in a one-to-one correspondence with the second plugging holes 211, and at most one end of the second conductive pin 230 is located outside the second isolation position 221. In this way, when the number of the second conductive pins 230, the second plugging holes 211 and the second isolation position 221 are all two, two second conductive pins 230 are fixed in a one-to-one correspondence with the second plugging holes 211, and at most one end of the second conductive pin 230 is located outside the second isolation position 221, that is, the two ends of another second conductive pin 230 are located in the second isolation position 221. At this time, the ends of the two second conductive pins 230 can be separated by the action of the two second isolation positions 221. At this time, during the soldering process, the two second conductive pins 230 can be prevented from sticking, thereby preventing the second connecting portion 200 from sticking.

[0048] In this embodiment, when the second mounting seat 210 is connected to the first mounting seat 110, the second conductive pins 230 are inserted into the first isolation position 121 one by one, so that the second conductive pins 230 are connected to the first conductive pins 130. At the same time, under the effect of the second connecting portion 200 structure, the situation of tin sticking between the two second conductive pins 230 can be avoided. When the first connecting portion 100 and the second connecting portion 200 are connected to form a waterproof electrical connector, the short circuit of the waterproof electrical connector can be effectively avoided, thereby solving the technical problems existing in the prior art. In this embodiment, the connection between the first conductive pin 130 and the second conductive pin 230 can be a direct connection in the form of contact, or it can be an indirect connection, wherein the indirect connection method is that a conductive member is provided between the first conductive pin 130 and the second conductive pin 230, and the first conductive pin 130 and the second conductive pin 230 are both connected to the conductive member, and the first conductive pin 130 and the second conductive pin 230 are connected through the conductive member.

[0049] In one embodiment, reference Figure 1 The first connection part 100 and the second connection part 200 are plugged into each other, so as to facilitate the installation of the waterproof electrical connector and further improve the assembly efficiency of the waterproof electrical connector when in use.

[0050] In this embodiment, reference Figure 1 , Figure 2, wherein the plug-in structure between the first connecting part 100 and the second connecting part 200 can adopt the following structure, a slot 240 is provided at one end of the second mounting seat 210 away from the second isolation seat 220, and the slot 240 is used for plugging in one end of the first mounting seat 110 away from the first isolation seat 120; in the present embodiment, one end of the second conductive needle 230 away from the second isolation seat 220 is located in the slot 240, and when the first mounting seat 110 and the second mounting seat 210 are plugged in, the end of the second conductive needle 230 away from the second isolation seat is inserted into the first plug hole 111 of the first mounting seat 110, so that the first conductive needle 130 and the second conductive needle 230 are connected.

[0051] In one embodiment, reference Figure 1 , Figure 2 One of the first mounting seat 110 and the second mounting seat 210 is provided with an anti-idiot groove 140, and the other is provided with an anti-idiot block 250 corresponding to the anti-idiot groove 140. The anti-idiot groove 140 is plugged into the anti-idiot block 250. This is to prevent the first mounting seat 110 and the second mounting seat 210 from rotating during the plug-in process, and to prevent the second conductive pin 230 from being twisted and damaged.

[0052] In one embodiment, reference Figure 1 , an anti-idiot groove 140 is provided on the first mounting seat 110, and an exhaust groove 150 is provided at one end of the first mounting seat 110 away from the first isolation seat 120, and the exhaust groove 150 is connected to the anti-idiot groove 140, and the anti-idiot groove 140 is loosely matched with the anti-idiot block 250; under the action of the exhaust groove 150, it is prevented that a lot of gas is accumulated inside the waterproof electrical connector after the first mounting seat 110 and the second mounting seat 210 are assembled, and when the gas pressure is high, the conductive pin (the first conductive pin 130 or the second conductive pin 230) will be oxidized; the specific operation is that when the first mounting seat 110 and the second mounting seat 210 are in the process of plugging, the gas in the two can enter the anti-idiot groove 140 through the exhaust groove 150, and be discharged to the outside of the waterproof electrical connector through the anti-idiot groove 140, thereby preventing air from being accumulated inside the waterproof electrical connector.

[0053] In one embodiment, reference Figure 1 , Figure 2 , the first isolation position 121 includes a first groove opened on the outside of the first isolation seat 120 and a first through hole opened on the first isolation seat 120, wherein at most one end of a first conductive needle 130 is located outside the first isolation position, and is preferably located outside the first through hole;

[0054] And / or, the second isolation position 221 includes a second groove opened outside the second isolation seat 220 and a second through hole opened on the second isolation seat 220, wherein at most one end of a second conductive needle 230 is located outside the first isolation position, and is preferably located outside the second through hole. In this embodiment, the groove facilitates soldering between the connecting wire and the conductive needle, making the product easier to use.

[0055] In one embodiment, reference Figure 4 , the second mounting seat 210 is provided with a threaded section 400 on the outside, and the first mounting seat 110 is rotatably mounted with a nut 300 on the outside, wherein the nut 300 and the first mounting seat 110 can be sealed; the nut 300 is connected to the threaded section 400. In this embodiment, in order to avoid the separation of the first mounting seat 110 and the second mounting seat 210, the first connection part 100 and the second connection part 200 are disconnected. After the first connection part 100 and the second connection part 200 are connected, the nut 300 is connected with the threaded section 400, so that the first connection part 100 and the second connection part 200 can be stably connected together, and at the same time, under the action of the nut 300 and the threaded section 400, a waterproof sealing effect can be achieved on the connection. In this embodiment, after the nut 300 and the threaded section 400 are connected, the second mounting seat 210 in the second connection part 200 will squeeze the waterproof ring 160, so that a seal is formed between the second mounting seat 210 and the waterproof ring 160, thereby achieving a sealing effect.

[0056] In one embodiment, the first connection part 100 and the second connection part 200 are both configured as an integrally formed part, wherein the integrally formed part of the first connection part 100, i.e., the first mounting seat 110, the first isolation seat 120, the first isolation position 121, the first plug hole 111 and the first conductive pin 130 are integrally formed, and the same is true for the integrally formed part of the second connection part 200. In other embodiments, the integrally formed part of the first connection part 100, i.e., the first mounting seat 110, the first isolation seat 120, the first isolation position 121, the first plug hole 111, the first conductive pin 130, the foolproof groove 140 and the exhaust groove 150 are integrally formed.

[0057] In one embodiment, reference Figure 5 The second mounting seat 210 is provided with a limiting portion 500 on the outside. This is to prevent the waterproof electrical connector from self-rotating when the waterproof electrical connector is used in different scenarios. The limiting portion 500 cooperates with other structures to limit the self-rotation of the waterproof electrical connector. The limiting portion 500 can be configured as a flat position provided on the outside of the second mounting seat 210, and a protrusion corresponding to the flat position is provided on other structures, wherein the flat position and the protrusion abut against each other, thereby limiting the waterproof electrical connector from self-rotating.
