Description

Technical Field

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

[0002] Connector assemblies consist of male and female plugs and are widely used in various fields, including automotive, communications, computer and other consumer electronics, industrial, and transportation sectors. Applicable vehicle types include new energy vehicles, electric bicycles, electric motorcycles, and electric scooters. As key components, the male and female plugs act as a bridge between circuits, allowing current to flow and enabling the circuit to perform its intended function. Both male and female plugs have wires threaded through their ends, which are soldered to conductive terminals inside the connector. However, when the wires of the male and female plugs are subjected to external tension, the lack of any internal protective structure makes them prone to wire detachment or conductor breakage at the solder joints, leading to poor contact. Utility Model Content

[0003] The purpose of this utility model is to provide a connector and a connector assembly having the aforementioned connector.

[0004] This utility model provides a connector, comprising a first rubber core, a connecting sleeve, a waterproof adhesive, and a rear cover. The first rubber core is provided with a conductive terminal. The connecting sleeve is sealed to one end of the first rubber core. The connecting end of the conductive terminal is housed in the inner cavity of the connecting sleeve, and one end of a conductive wire is connected to the connecting end of the conductive terminal. The waterproof adhesive fills the inner cavity of the connecting sleeve at one end away from the first rubber core, and the waterproof adhesive wraps around the connecting end of the conductive terminal and the conductive wire. The rear cover is connected to the connecting sleeve at the end away from the first rubber core.

[0005] This utility model also provides a connector assembly, the connector assembly including a connector and another connector that mates with the first connector. The connector includes a first core, a connecting sleeve, a waterproof colloid, and a rear cover. The first core is provided with a conductive terminal. The connecting sleeve is sealed to one end of the first core. The connecting end of the conductive terminal is housed in the inner cavity of the connecting sleeve. One end of a conductive wire is connected to the connecting end of the conductive terminal. The waterproof colloid fills the inner cavity of the connecting sleeve at one end away from the first core. The waterproof colloid wraps around the connecting end of the conductive terminal and the conductive wire. The rear cover is connected to the connecting sleeve at one end away from the first core and abuts against the waterproof colloid. The other connector includes a second core. The first core and the second core of the connector are interlocking. The first sealing ring and the second sealing ring of the connector are sealed between the second core and the first core.

[0006] The waterproof colloid in this connector fills the inner cavity of the connecting sleeve and wraps around the connection between the connecting end and the conductive wire. The back cover is connected to the connecting sleeve, so that the back cover abuts against the waterproof colloid. When external tension is applied to the conductive wire, the waterproof colloid prevents the conductive wire from detaching from the connecting end or prevents the conductive wire inside the connector from breaking, thus maintaining good contact between the conductive wire and the conductive terminal. Secondly, compared to the existing male or female plugs with a large gap inside the connecting sleeve, when the existing male or female plugs are in a deep-water working environment, the connecting sleeve may cause water to enter or even burst due to the large pressure difference between the inside and outside. However, the connecting sleeve of this connector is filled with waterproof colloid. When the connector is in a deep-water working environment, the pressure difference between the inside and outside of the connecting sleeve is small or non-existent, thereby avoiding the risk of water ingress and damage to the connector.

[0023] Please see Figure 1 and Figure 3 The first embodiment of this utility model provides a connector assembly 100, which includes a connector 20 and another connector 40. The connector 20 includes a first core 22, a connecting sleeve 23, a waterproof adhesive 24, and a rear cover 25. The first core 22 is provided with conductive terminals 220. Specifically, the conductive terminals 220 include power terminals 2201 and signal terminals 2203, which are respectively disposed on the first core 22. In this embodiment, the conductive terminals 220 include two power terminals 2201 and ten signal terminals 2203. The connecting sleeve 23 is sealed to one end of the first core 22, and the connecting end 2204 of the conductive terminal 220 is accommodated in the inner cavity 25 of the connecting sleeve 23. 30. One end of the conductive wire 101 is connected to the connection end 2204 of the conductive terminal 220. Specifically, one end of the conductive wire 101 and the connection end 2204 can be connected by, but is not limited to, welding, snap-fitting, or screwing. The waterproof colloid 24 fills the end of the inner cavity 230 of the connecting sleeve 23 that is away from the first core 22, and the waterproof colloid 24 seals the connection end 2204 of the conductive terminal 220 and the conductive wire 101. The rear cover 25 is connected to the end of the connecting sleeve 23 that is away from the first core 22, and the rear cover 25 abuts against the waterproof colloid 24. The other connector 40 includes a second core 42, and the first core 22 and the second core 42 can be interlocked to make the connector 20 electrically connected to the other connector 40. One of the connectors 20 and the other connector 40 can be a male plug and the other can be a female plug. In this embodiment, the connector 20 is a male plug and the other connector 40 is a female plug.

[0024] The waterproof colloid 24 of the connector 20 of this application fills the inner cavity 230 of the connecting sleeve 23, and the waterproof colloid 24 covers the connection between the connecting end 2204 and the conductive wire 101. The back cover 25 is connected to the connecting sleeve 23, so that the back cover 25 abuts against the waterproof colloid 24. When an external pulling force is applied to the conductive wire 101, the waterproof colloid 24 can prevent the conductive wire 101 from detaching from the connecting end 2204 or can prevent the conductive wire 101 in the connector 20 from breaking, so that the conductive wire 101 and the conductive terminal 220 maintain good contact. Secondly, compared with the prior art, The internal cavity of the male or female connector sleeve in the present invention has a large gap.

Specifically, the second adhesive core 42 includes a second positioning part 421, a second insertion part 423, and a second connecting part 425. The second positioning part 421 is a second circular block, the second insertion part 423 is a second insertion cylinder connected to one end of the second positioning part 421, and the second connecting part 425... 25 is a second connecting cylinder connected to the other end of the second positioning part 421. The second positioning part 421, the second insertion part 423 and the second connecting part 425 are coaxial. The outer diameter of the second positioning part 421 is larger than the outer diameter of the second insertion part 423 and the outer diameter of the second positioning part 425 is larger than the outer diameter of the second connecting part 425. The outer diameter of the second insertion part 423 may be the same as or different from the outer diameter of the second connecting part 425. The outer circumferential surface of the second connecting part 425 is provided with an external thread, and the inner cavity of the second connecting sleeve 43 is provided with an internal thread at the end near the second rubber core 42. The external thread is screwed into the internal thread. The second connecting portion 425 has a second waterproof flange 4255 at one end opposite to the second insertion portion 423. The second waterproof flange 4255 is coaxial with the second connecting portion 425. The second connecting sleeve 43 has a second waterproof annular groove 433 at one end with an internal thread. The internal thread is located on the inner circumferential surface of the second waterproof annular groove 433. The second waterproof flange 4255 can be inserted into the second waterproof annular groove 433. The other connector 40 also includes a fifth sealing ring 4257, which is housed in the second waterproof annular groove 433 and is sealed and clamped by the inner surfaces of the second waterproof flange 4255 and the second waterproof annular groove 433. One end of the conductive wire 101 is housed in the inner cavity of the second connecting sleeve 43, and the conductive wire 101 is welded to the first conductive cylinder 4252 and the second conductive cylinder 4254.

The second rear cover 45 is connected to the end of the second connecting sleeve 43 away from the second core 42, so that the second rear cover 45 abuts against the second waterproof adhesive 44. When an external pulling force is applied to the conductive wire 101, the second waterproof adhesive 44 can prevent the conductive wire 101 from detaching from the first conductive cylinder 4252 and the second conductive cylinder 4254, and can also prevent the conductive wire 101 in the other connector 40 from breaking, so that the conductive wire 101 and the first The conductive cylinder 4252 and the second conductive cylinder 4254 maintain good contact. Secondly, compared with the female plug in the prior art, which has a large gap inside the middle sleeve, when the female plug in the prior art is in a deep water working environment, the middle sleeve may cause water to enter the female plug or even burst due to the large pressure difference between the inside and outside. However, the inner cavity of the second connecting middle sleeve 43 of the other connector 40 of this application is filled with a second waterproof colloid 44. When the other connector 40 is in a deep water working environment, the pressure inside and outside the second connecting middle sleeve 43 is small or there is no pressure difference, so the other connector 40 is less likely to be water-entered or crushed. Therefore, the other connector 40 can be used in deep water or high pressure environments.

[0040] A second connecting ring 435 protrudes from one end of the second connecting sleeve 43 away from the second rubber core 42. The second connecting ring 435 and the second connecting sleeve 43 are coaxial.

Two second snap-fit ​​holes 452 are opened on the second peripheral wall 455, located at opposite ends of one radial direction of the second peripheral wall 455. When the second rear cover 45 covers the second connecting ring 435, the two second snap-fit ​​blocks 4355 are respectively snapped into the two second snap-fit ​​holes 452.

[0044] like Figures 2-3 and Figure 5As shown, when assembling connector 20, power terminal 2201 and signal terminal 2203 are pressed into the first positioning groove and second positioning groove of first core 22 respectively using a hand press or pneumatic fixture; locking ring 28 is sleeved on first core 22, so that auxiliary rotating ring edge 285 is rotatably accommodated in auxiliary rotating ring groove 2212, and auxiliary rotating ring edge 285 is stopped by stop flange 2214; third sealing ring 2272 is sleeved in receiving ring groove 2252 of first connecting part 225 of first core 22, and fourth sealing ring 2274 is accommodated in waterproof ring groove 233 of connecting sleeve 23; the end of connecting sleeve 23 away from connecting ring 235 is screwed to first connecting part 225, that is, the first internal thread 232 and the first external thread 2254 are screwed together, so that the third sealing ring 2272 and the fourth sealing ring 2274 are respectively sealed and clamped between connecting sleeve 23 and first core 22. Cut the wires, then strip the insulation, tin them, and pass them sequentially through the first through hole 257 of the back cover 25 and the second through hole 262 of the first sealing member 26. Place the wires in the inner cavity 230 of the connecting sleeve 23 and solder them to the connection end 2204 of the power terminal 2201 and the signal terminal 2203. Fill the inner cavity 230 of the connecting sleeve 23 with glue to form a waterproof colloid 24, so that the waterproof colloid 24 seals the connection end 2204 of the conductive terminal 220 and the conductive wire 101. Place the first sealing member 26 in the inner cavity of the connecting ring 235 and contact the first stop 2352. Sleeve the back cover 25 onto the connecting ring 235, so that multiple snap-fit ​​blocks 2355 can snap into multiple snap-fit ​​holes 252 respectively. The first sealing member 26 is sealed between the back cover 25 and the connecting sleeve 23, and the first sealing member 26 is sealed onto the conductive wire 101. The second sealing ring 227 is fitted onto the first insertion part 223 of the first rubber core 22 and contacts the stop ring surface 2216; the two first sealing rings 226 are respectively fitted onto the two positioning ring grooves 2232 of the first rubber core 22.

[0045] The assembly method of the other connector 40 is similar to that of connector 20, and will not be described in detail here.

[0046] like Figure 1 and Figure 6As shown, when connector 20 needs to be plugged into another connector 40, the first core 22 of connector 20 is inserted into the connecting ring groove 420 of the second core 42, so that the two power terminals 2201 are respectively inserted into the two first positioning grooves 436, and the ten signal terminals 2203 are respectively inserted into the ten signal plug holes 437; the locking ring 28 is rotatably sleeved on the connecting cylinder 422, and the second internal thread 282 and the second external thread 4221 are threaded together so that the first core 22 and the second core 42 come closer to each other until the multiple positioning blocks 4224 are respectively engaged in the multiple positioning grooves 284 to prevent the locking ring 28 from loosening or falling off relative to the connecting cylinder 422. At this time, the two power terminals 2201 are respectively inserted into the two first conductive cylinders 4252, and each signal terminal 2203 is inserted into the corresponding second conductive cylinder 4254. The two first sealing rings 226 are sealed between the first insertion part 223 and the second insertion part 423 to form two sealed waterproof structures. The second sealing ring 227 is sealed between the second insertion part 423 and the stop flange 2214 to form one sealed waterproof structure. The sealing ring 41 is sealed between the first insertion part 223 and the second positioning part 421 to form one sealed waterproof structure. Therefore, after the connector 20 is inserted into another connector 40, four sealed waterproof structures are formed between them, which improves the waterproof effect.

[0047] Because the third sealing ring 2272 and the fourth sealing ring 2274 are sealed and clamped between the first rubber core 22 and the connecting sleeve 23, a double-seal waterproof structure is formed between the first rubber core 22 and the connecting sleeve 23, improving the waterproof effect; the inner cavity of the connecting sleeve 23 is filled with waterproof adhesive 24, and the first sealing member 26 is sealed and fitted onto the outside of the conductive wire 101, forming a double-seal waterproof structure between the conductive wire 101 and the power terminal 2201 and the signal terminal 2203, improving the waterproof effect; similarly Since two sealing rings are provided between the second connecting part 425 and the second connecting sleeve 43, two sealing waterproof structures are formed between the second connecting part 425 and the second connecting sleeve 43, improving the waterproof effect; the inner cavity of the second connecting sleeve 43 is filled with the second waterproof colloid 44, and the second sealing member 46 is sealed to the outside of the conductive wire 101, so as to form two sealing waterproof structures between the conductive wire 101 and the first conductive cylinder 4252 and the second conductive cylinder 4254, improving the waterproof effect. When the connector assembly 100 is used in deep water, the connector assembly 100 has a strong waterproof effect due to the multiple sealing and waterproof structures between the connector 20, the other connector 40, and the connector 20 and the other connector 40, preventing water from entering the connector assembly 100. Secondly, since the inner cavity of the connecting sleeve 23 is filled with waterproof colloid 24 and the inner cavity of the second connecting sleeve 43 is filled with second waterproof colloid 44, the pressure inside and outside the connecting sleeve 23 and the second connecting sleeve 43 is small or there is no pressure difference, avoiding the risk of water entering the connector 20 and the other connector 40 and being crushed.

[0048] like Figures 9-11As shown, the structure of the connector assembly 100a provided in the second embodiment of this application is similar to that of the connector assembly 100 in the first embodiment. The difference lies in that the connection relationship and waterproof structure between the connecting sleeve 23 and the first rubber core 22a in the second embodiment are slightly different from those in the first embodiment. Furthermore, the structures of the first sealing element 26a and the rear cover 25a in the second embodiment are slightly different from those in the first embodiment. Specifically, in the second embodiment, in addition to being screwed together, the first connecting portion 225 of the connecting sleeve 23a and the first rubber core 22a is also positioned by the cooperation of a locking block and a locking groove.

Preferably, the outer peripheral surface of the first connecting part 225 is provided with four locking blocks 2255, and the four locking blocks 2255 are arranged in a circle with uniform intervals around the circumference of the first connecting part 225. The inner peripheral surface of the connecting sleeve 23a is provided with multiple locking grooves 236, and the multiple locking grooves 236 are arranged in a circle with uniform intervals around the circumference of the connecting sleeve 23a.

[0049] In other embodiments, the outer peripheral surface of the first connecting portion 225 near the end of the first positioning portion 221 is provided with a plurality of locking grooves, which are arranged in a circle around the circumference of the first connecting portion 225; the inner peripheral surface of the connecting sleeve 23a near the first adhesive core 22a is provided with a plurality of locking blocks, which are arranged in a circle around the circumference of the connecting sleeve 23a; when the connecting sleeve 23a is screwed onto the first connecting portion 225, the plurality of locking blocks are respectively locked into the plurality of locking grooves to prevent the connecting sleeve 23a from retracting and disengaging relative to the first adhesive core 22a.

[0051] Optionally, the end face of the connecting sleeve 23a opposite to the first rubber core 22a is provided with a first positioning ring groove 237, and the first sealing member 26a is a sealing ring housed in the first positioning ring groove 237, which surrounds the waterproof adhesive 24; the rear cover 25a is threadedly connected to the connecting sleeve 23a, and the rear cover 25a compresses the sealing ring. Specifically, the connecting sleeve 23a and the rear cover 25a are threadedly connected, that is, the end of the connecting sleeve 23a opposite to the locking groove 236 has an external thread on its outer circumferential surface, and the inner circumferential surface of the rear cover 25a has an internal thread. The end of the connecting sleeve 23a away from the locking groove 236 is provided with multiple fastening strips. When the rear cover 25a is connected to the connecting sleeve 23a, the rear cover 25a compresses the multiple fastening strips and they move closer together.

[0052] When assembling connector 20a, power terminal 2201 and signal terminal 2203 are pressed into the first positioning groove and second positioning groove of first core 22a respectively using a hand press or pneumatic fixture; one of the first sealing rings 226 is fitted into the first fixing ring groove 2256 of the first connecting part 225; the locking ring 28 is fitted into the first core 22a, so that the locking ring 28 is rotatably fitted into the first core 22a and stopped by the stop flange 2214; the connecting sleeve 23 is then... One end of the connecting sleeve 23a with a locking groove 236 is fitted onto the first connecting part 225, so that the connecting sleeve 23a is screwed onto the first connecting part 225, until multiple locking blocks 2255 are respectively engaged with multiple locking grooves 236 to prevent the connecting sleeve 23a from retracting and detaching relative to the first core 22a. The first sealing ring 226 is sealed and clamped between the connecting sleeve 23a and the first connecting part 225. After cutting the wire, the wire is stripped, tinned, and then passed through the back cover 25a in sequence. The through groove and the wire hole of the first sealing member 26a are used to house the wire in the inner cavity of the connecting sleeve 23a and weld it to the connection end of the power terminal 2201 and the signal terminal 2203; glue is filled into the inner cavity of the connecting sleeve 23a to form a waterproof colloid 24, so that the waterproof colloid 24 seals the connection end of the power terminal 2201 and the signal terminal 2203 and the conductive wire 101; the first sealing member 26a is housed in the first positioning ring groove of the connecting sleeve 23a. 237. The rear cover 25a is fitted onto the end of the connecting sleeve 23a opposite to the first rubber core 22a. The rear cover 25a and the connecting sleeve 23a are screwed together, so that the rear cover 25a presses multiple fastening strips together to secure the first sealing member 26a. The first sealing member 26a is sealed between the rear cover 25a and the connecting sleeve 23a, and the first sealing member 26a is sealed onto the conductive wire 101.

The second sealing ring 227 is fitted onto the first insertion part 223 of the first rubber core 22a and contacts the stop ring surface 2216; the two first sealing rings 226 are respectively fitted into the two positioning ring grooves 2232 of the first rubber core 22.

[0053] In the second example connector 20a, the first sealing ring 226 between the first connecting sleeve 23a and the first adhesive core 22a forms a waterproof structure, and the waterproof adhesive 24 forms a waterproof structure at the front end of the first connecting sleeve 23a. Therefore, two waterproof structures are formed between the connector 20a and the first adhesive core 22a, enhancing the waterproof capability. The end of the connector 20a facing away from the other connector 40a forms two waterproof structures with the waterproof adhesive 24 and the first sealing element 26a, further enhancing the waterproof capability. Furthermore, since the waterproof adhesive 24 fills the inner cavity of the first connecting sleeve 23a and covers the solder joints of the conductive wire and the conductive terminal, when the conductive wire is subjected to external tension, the waterproof adhesive 24 effectively protects the solder joints, reducing the stress on the solder joints and reducing the risk of wire breakage.

[0054] like Figure 9 and Figure 12 As shown, in the second embodiment, in addition to being screwed together, the second connecting part 425 of the second connecting sleeve 43a and the second adhesive core 42a is also positioned by the cooperation of a locking block and a locking groove.

[0056] Optionally, the outer peripheral surface of the second connecting part 425 is provided with a second adhesive ring groove 4256. The second adhesive ring groove 4256 is coaxial with the second connecting part 425 and is located between the locking block and the external thread. The sealing ring sleeve 428 is positioned in the second adhesive ring groove 4256, and both sealing flanges of the sealing ring sleeve 428 protrude from the outer peripheral surface of the second connecting part 425. When the second connecting sleeve 43a is screwed onto the second connecting part 425, the sealing ring sleeve 428 is sealed and clamped between the second connecting sleeve 43a and the second connecting part 425, and the locking block is respectively locked into multiple locking grooves, which not only prevents the second connecting sleeve 43a from retracting relative to the second connecting part 425 but also improves the waterproof effect.

[0057] Optionally, the second connecting sleeve 43a has a second positioning ring groove 438 on its end face opposite to the second rubber core 42a, and the second sealing member 46a is a sealing ring housed in the second positioning ring groove 438, which surrounds the second waterproof adhesive 44; the second rear cover 45a is threadedly connected to the second connecting sleeve 43a, and the second rear cover 45a presses against the sealing ring. Specifically, the second connecting sleeve 43a and the second rear cover 45a are threadedly connected, that is, the end of the second connecting sleeve 43a opposite to the second rubber core 42a has an external thread on its outer circumferential surface, and the inner circumferential surface of the second rear cover 45a has an internal thread. The second connecting sleeve 43a has multiple fastening strips at the end away from the second rubber core 42a. When the second rear cover 45a is connected to the second connecting sleeve 43a, the second rear cover 45a squeezes the multiple fastening strips together to fasten the second sealing member 46a. The second sealing member 46a is sealed between the second rear cover 45a and the second connecting sleeve 43a, and the second sealing member 46a is sealed to the conductive wire 101. This threaded waterproof structure can greatly improve the stability of waterproofing.

[0058] In the second example, the sealing ring 428 between the second connecting sleeve 43a and the second core 42a in the other connector 40a forms a waterproof structure, and the second waterproof adhesive 44 forms a waterproof structure at the front end of the second connecting sleeve 43a. Therefore, two waterproof structures are formed between the other connector 40a and the second core 42a, enhancing the waterproof capability. The end of the other connector 40a opposite to connector 20a forms two waterproof structures with the second waterproof adhesive 44 and the second seal 46a, further enhancing the waterproof capability. Furthermore, since the second waterproof adhesive 44 fills the inner cavity of the second connecting sleeve 43a and covers the solder joints of the conductive wire and the conductive terminal, when the conductive wire is subjected to external tension, the second waterproof adhesive 44 effectively protects the solder joints, reducing the stress on the solder joints and reducing the risk of wire breakage.

[0059] like Figure 12 As shown, after connector 20a and another connector 40a are mated, the interiors of both connector 20a and the other connector 40a are filled with glue to form a solid, which greatly enhances the waterproof capability. This allows connector 20a and the other connector 40a to work in deep water without worrying about the waterproof capability of the connector combination, or the problem of insufficient waterproof capability due to strong underwater pressure or the problem of being squeezed and burst by water pressure.
