Description

Technical Field

[0001] This application relates to the technical field of electronic connectors, and particularly to a connector. Background Art

[0002] Connectors are currently widely used in various electrical connection places, especially in large equipment. To ensure the continuous and reliable operation of the equipment, the primary requirement for connectors is a stable connection relationship and not being easily detached. At the same time, these plugs and sockets usually need to be used for a relatively long time, and the connectors are required to be strong and durable. For example, a metal push-pull self-locking connector disclosed in patent application CN118299869A. The plug includes a plug body and a first mating structure member, and the socket includes a socket body and a second mating structure member. The metal sleeve of the plug body is inserted into the metal housing of the socket body, and the elastic pawls at the end of the metal sleeve are elastically received in the keyway of the metal housing. The first mating structure member is inserted into the metal sleeve, and the second mating structure member is inserted into the metal housing, and the first mating structure member and the second mating structure member are mated to form a mating connection structure. Connectors with similar structures can be very commonly used in the connection of various devices.

[0003] With the widespread application of connectors, people have put forward higher requirements for connectors. Currently, the wiring methods of the terminals (pins, or pins and wires) of connectors are mainly welding, board connection, and crimping. These three wiring methods do not have relevant pre-installability and have low error tolerance. Summary of the Invention

[0004] Based on this, in view of the problem that the wiring methods of connectors in the prior art do not have relevant pre-installability and have low error tolerance, it is necessary to provide a connector.

[0005] This application provides a connector, including:

[0006] A socket, including a socket housing and at least one pin disposed at least partially within the socket housing;

[0007] A plug, including a connection ring, a plug housing, a tail housing, a tail nut, a jack assembly, and at least one first screw. The connection ring is fixedly connected to the plug housing, the plug housing is threadedly connected to the tail housing, the tail housing is threadedly connected to the tail nut, the jack assembly is installed in the plug housing, and the jack assembly includes at least one jack corresponding to the pin;

[0008] Wherein, after the plug and the socket are mated and connected, the pin is inserted into the corresponding jack, and the pin is fixed in the jack by the first screw.

[0009] In some embodiments, each of the jacks corresponds to at least one of the first screws;

[0010] After the plug is inserted into the socket, the first screw fixes the pin and the wire in the jack, and the pin contacts the wire.

[0011] In some embodiments, the socket includes a pin assembly disposed in the socket housing. The pin assembly includes a plurality of pins and pin holes, and the pins are disposed in the pin holes.

[0012] The socket further includes a second screw, and the pin is fixed in the pin hole by the second screw.

[0013] In some embodiments, each of the pin holes corresponds to at least one of the second screws;

[0014] The second screw fixes the pin and the wire in the pin hole, and the pin contacts the wire.

[0015] In some embodiments, after the plug is inserted into the socket, the first screw fixes the pin and the wire in the jack, and the pin contacts the wire. The second screw fixes the pin and the wire in the pin hole, and the wire in the pin hole and the wire in the jack are different wires.

[0016] In some embodiments, after the plug is inserted into the socket, the first screw fixes the pin and the wire in the jack, and the pin contacts the wire. The second screw fixes the pin and the wire in the pin hole, and the wire in the pin hole and the wire in the jack are the same wire.

[0017] In some embodiments, the outer surfaces of the connecting ring and the tail nut both include vertical stripe protrusions or vertical stripe grooves parallel to the insertion direction of the plug into the socket.

[0018] In some embodiments, further included is:

[0019] A first sealing ring disposed at the connection between the plug housing and the tail housing and located between the plug housing and the tail housing.

[0020] In some embodiments, further included is:

[0021] A second sealing ring. After the plug is inserted into the socket, the second sealing ring is disposed at the connection between the socket housing and the plug housing and located between the socket housing and the plug housing.

[0022] In some embodiments, the socket housing is a flange structure

[0023] In the embodiments of the present application, after the plug and the socket are inserted and connected, the pin is inserted into the corresponding jack, and the pin is fixed in the jack by a first screw. On the one hand, the first screw fixes the pin in the jack, which helps to prevent the plug and the socket of the connector from separating. On the other hand, compared with the prior art in which the pin is fixed in the jack by welding, plate connection and crimping, by using the first screw, the insertion connection relationship between the pin and the jack can be reconnected or disconnected without destructive disassembly, so that the connection method of the present application has good pre-installability (for example, pre-installed for testing) and high fault tolerance (for example, reinstalled after improper installation). On the third hand, the first screw strengthens the tight contact connection relationship between the pin and the corresponding wire in the jack, reducing the contact resistance.

[0040] This application provides a connector 100, please refer to Figures 1 to 4, the connector 100 includes a socket 10 and a plug 20. The socket 10 includes a socket housing 11 and at least one pin 122 disposed at least partially within the socket housing 11; the plug 20 includes a connection ring 21, a plug housing 22, a tail housing 23, a tail nut 24, a jack assembly 25, and at least one first screw 26. The connection ring 21 is fixedly connected to the plug housing 22. The plug housing 22 is threadedly connected to the tail housing 23. The tail housing 23 is threadedly connected to the tail nut 24. The jack assembly 25 is installed within the plug housing 22. The jack assembly 25 includes at least one jack 251 corresponding to the pin 122. Wherein, after the plug 20 and the socket 10 are inserted and connected, the pin 122 is inserted into the corresponding jack 251, and the pin 122 is fixed within the jack 251 by the first screw 26.

[0041] Exemplarily, after the plug 20 and the socket 10 are inserted and connected, electrical conduction can be achieved between the wire at one end of the socket 10 and the wire at one end of the plug 20.

[0042] Exemplarily, a part of the plug housing 22 and a part of the tail housing 23 are located within the connection ring 21, and a part of the plug housing 22 is located within the tail housing 23; the external thread on the outer surface of the plug housing 22 is connected to the internal thread on the inner surface of the tail housing 23.

[0043] Exemplarily, a part of the tail housing 23 is located within the tail nut 24, and the external thread on the outer surface of the tail housing 23 is connected to the internal thread on the inner surface of the tail nut 24.

[0044] Exemplarily, after the plug 20 and the socket 10 are inserted and connected, a part of the socket housing 11 is located within the connection ring 21, and the external thread on the outer surface of the socket housing 11 is connected to the internal thread on the inner surface of the connection ring 21.

[0045] Exemplarily, after the plug 20 and the socket 10 are inserted and connected, the socket housing 11 and the plug housing 22 are located at both ends within the cavity of the connection ring 21.

[0046] Exemplarily, the jack assembly 25 is installed within the plug housing 22. The jack assembly 25 includes at least one jack 251 corresponding to the pin 122. For example, the jack assembly 25 may include 3 or more jacks 251.

[0047] Exemplarily, the number of pins 122 is the same as the number of jacks 251.

[0048] In an embodiment of the present application, after the plug 20 is inserted and connected to the socket 10, the pin 122 is inserted into the corresponding jack 251, and the pin 122 is fixed in the jack 251 by the first screw 26. On the one hand, the first screw 26 fixes the pin 122 in the jack 251, which helps to prevent the plug 20 and the socket 10 of the connector 100 from separating. On the other hand, compared with the prior art in which the pin 122 is fixed in the jack 251 by welding, board connection and crimping, the insertion connection relationship between the pin 122 and the jack 251 can be reconnected or disconnected without destructive disassembly by the first screw 26, making the connection method of the present application have good pre-installability (for example, pre-installed for testing) and high fault tolerance (for example, reinstalled after improper installation). On the third hand, the first screw 26 strengthens the tight contact connection relationship between the pin 122 and the corresponding wire in the jack 251, reducing the contact resistance.

[0049] In some embodiments, such as Figure 2 and Figure 3 、 Figure 5 and Figure 6 shown, each jack 251 corresponds to at least one first screw 26; after the plug 20 is inserted and connected to the socket 10, the first screw 26 fixes the pin 122 and the wire in the jack 251, and the pin 122 contacts the wire.

[0050] Exemplarily, such as Figure 2 and Figure 3 、 Figure 5 and Figure 6 shown, each jack 251 can be correspondingly provided with one or more first screws 26. For example, the pin 122 is fixed in a jack 251 by 2 first screws 26, which can improve the mechanical strength of the fixed connection.

[0051] Exemplarily, such as Figure 2 and Figure 3 、 Figure 5 and Figure 6 shown, after the plug 20 is inserted and connected to the socket 10, the first screw 26 fixes the pin 122 and the wire in the jack 251, and the pin 122 contacts the wire, realizing the electrical conduction between the pin 122 and the wire, thereby realizing the electrical conduction between the wire at one end of the socket 10 and the wire at one end of the plug 20.

[0052] In some embodiments, such as Figure 4 、 Figure 5 and Figure 6 shown, the socket 10 includes a pin assembly 12, the pin assembly 12 is arranged in the socket housing 11, the pin assembly 12 includes a plurality of pins 122 and pin holes 121, the pins 122 are arranged in the pin holes 121, the socket 10 further includes a second screw 13, and the pins 122 are fixed in the pin holes 121 by the second screw 13.

[0053] Exemplarily, the pin assembly 12 includes one or more pin holes 121, and one end of the pin 122 is fixed in the pin hole 121 by the second screw 13. In the first aspect, compared with the prior art in which the pin 122 is fixed in the pin hole 121 by welding, plate connection and crimping, the insertion connection relationship between the pin 122 and the pin hole 121 can be reconnected or disconnected without destructive disassembly by the second screw 13, so that the connection method of the present application has good pre-installability (for example, pre-installed for testing) and high fault tolerance (for example, reinstalled after improper installation). In the second aspect, the second screw 13 strengthens the tight contact connection relationship between the pin 122 and the corresponding wire in the pin hole 121, and reduces the contact resistance.

[0054] In some embodiments, such as Figure 4 , Figure 5 and Figure 6 shown, each pin hole 121 corresponds to at least one second screw 13; the second screw 13 fixes the pin 122 and the wire in the pin hole 121, and the pin 122 contacts the wire.

[0055] Exemplarily, as Figure 4 , Figure 5 and Figure 6 shown, each pin hole 121 can be correspondingly provided with one or more second screws 13. For example, the pin 122 is fixed in a pin hole 121 by 2 second screws 13, which can improve the mechanical strength of the fixed connection.

[0056] In some embodiments, such as Figure 1 and Figure 5 shown, after the plug 20 and the socket 10 are inserted and connected, the first screw 26 fixes the pin 122 and the wire in the jack 251, the pin 122 contacts the wire, and the second screw 13 fixes the pin 122 and the wire in the pin hole 121. The wire in the pin hole 121 and the wire in the jack 251 are different wires.

[0057] Exemplarily, as Figure 5 shown, after the plug 20 and the socket 10 are inserted and connected, the first screw 26 fixes the pin 122 and the first wire 51 in the jack 251, the pin 122 contacts the first wire 51, and the second screw 13 fixes the pin 122 and the second wire 52 in the pin hole 121. The first wire 51 and the second wire 52 are different wires. The second wire 52, the pin 122, and the first wire 51 are electrically conducted in sequence.

[0058] The wire, the first wire 51, and the second wire 52 can be electric wires.

[0059] In some embodiments, such as Figure 1 andFigure 6 As shown, after the plug 20 and the socket 10 are inserted and connected, the first screw 26 fixes the pin 122 and the wire in the jack 251, the pin 122 contacts the wire, the second screw 13 fixes the pin 122 and the wire in the pin hole 121, and the wire in the pin hole 121 and the wire in the jack 251 are the same wire.

[0060] Exemplarily, as Figure 6 shown, after the plug 20 and the socket 10 are inserted and connected, the first screw 26 fixes the pin 122 and the first wire 51 in the jack 251, the pin 122 contacts the first wire 51, the second screw 13 fixes the pin 122 and the second wire 52 in the pin hole 121, and the first wire 51 and the second wire 52 are the same wire. The same wire and the pin 122 are fixedly and contact-connected in the pin hole 121 through the second screw 13. At the same time, the same wire and the pin 122 are fixedly and contact-connected in the jack 251 through the first screw 26. On the one hand, compared with the prior art by means of welding, plate connection and crimping, through the second screw 13, the insertion connection relationship between the pin 122 and the pin hole 121 and the jack 251 can be reconnected or disconnected without destructive disassembly, so that the connection method of the present application has good pre-installability (for example, pre-installed for testing) and high fault tolerance (for example, reinstalled after improper installation). On the other hand, the simultaneous use of the first screw 26 and the second screw 13 optimally strengthens the tight contact connection relationship between the pin 122 and the corresponding wire in the pin hole 121 and the jack 251, reduces the contact resistance, and increases the connection mechanical strength.

[0061] In some embodiments, as Figure 1 and Figure 2 shown, the outer surfaces of the connecting ring 21 and the tail nut 24 both include vertical stripe protrusions or vertical stripe grooves 231 parallel to the insertion direction of the plug 20 and the socket 10. When the connecting ring 21 and the tail nut 24 are rotated by a finger or the like, the friction force can be increased, and the assembly convenience can be improved.

[0062] In some embodiments, as Figure 1 and Figure 2 shown, the connector 100 further includes a first sealing ring 28, and the first sealing ring 28 is arranged at the connection between the plug housing 22 and the tail housing 23 and is located between the plug housing 22 and the tail housing 23. The sealing performance and waterproof performance inside the connector 100 can be improved.

[0063] In some embodiments, as Figure 1 and Figure 2As shown, the connector 100 further includes a second sealing ring 27. After the plug 20 is inserted into the socket 10 in a mating manner, the second sealing ring 27 is disposed at the connection between the socket housing 11 and the plug housing 22 and is located between the socket housing 11 and the plug housing 22. This can improve the sealing performance and waterproof performance inside the connector 100.

[0064] In some embodiments, as Figure 4 shown, the socket housing 11 is a flange structure, which facilitates the arrangement of a plurality of pins 122 in the pin assembly 12. Fixed by screws, the structure is simple and the assembly is convenient.

[0065] It should be noted that, in some embodiments, the socket housing 11, the connection ring 21, the plug housing 22, the tail housing 23 and the tail nut 24 of the connector 100 are all made of PA66 material (polymerized polyamide resin). The PA66 material has good electrical performance and insulation performance, and characteristics such as fatigue resistance and corrosion resistance, which can improve the waterproof performance of the connector 100. The first screw 26 and the second screw 13 are both made of SUS304 stainless steel, which has the advantages of low price, excellent mechanical properties, processing properties and corrosion resistance.

[0066] It should be noted that, in some embodiments, the first sealing ring 28 and the second sealing ring 27 can be assembled first. The main function of these two sealing rings is to provide sealing, so that the entire connector 100 can reach the waterproof level IP67 after mating; the jack assembly 25 is assembled according to Figure 3 the assembly direction in Fig. (a) Figure 3 (the direction of the arrow in Fig. (a)). After assembly, the jack assembly 25 can be fixed in the plug housing 22 with screws; the third sealing ring 14 can be assembled first or last. The pin assembly 12 is assembled according to Figure 4 the assembly direction in Fig. (a) Figure 4 (the direction of the arrow in Fig. (a)). After assembly, the jack assembly 25 can be fixed in the socket housing 11 with screws. The advantages of this assembly method are: 1. The connector can be pre-installed during equipment verification; 2. It has a high fault tolerance rate. If the wire or cable is assembled incorrectly, it can be disassembled with a screwdriver and will not cause damage to the relevant equipment or the connector; it solves the problems of lack of relevant pre-installability and low fault tolerance rate.

[0067] It should be noted that the socket 10 may further include a tail seal 31 and a fourth sealing ring 32. The tail seal 31 and the fourth sealing ring 32 are used to seal the connection between the tail housing 23 and the tail nut 24, which can improve the sealing performance and waterproof performance inside the connector 100.

[0068] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the various technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.

[0069] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
