Description
Technical Field
[0001] This utility model relates to the field of electrical components technology, and in particular to a photoelectric storage connector that can prevent incorrect insertion of positive and negative terminals. Background Technology
[0002] With the rapid development of the energy storage industry, the wire assembly in the energy storage system carries the transmission of large currents inside the system. The plug in the wire assembly can be used with the socket to realize the quick connection in the system, which has the technical advantages of high efficiency and reliability. However, with the rapid development of the industry, there are also specific usage requirements for the wire assembly under different situations.
[0003] Currently, the 70A to 200A specifications of optical storage connectors on the market can be used as both positive and negative connectors. The two have the same structure. However, during use, since the cross-section of the socket on the plug and the pin on the socket is circular, and the positive and negative markings on the plug are usually not very obvious, it is easy to misinsert the positive and negative terminals. This will cause the circuit to malfunction or damage the electrical equipment. Therefore, it is necessary to improve the optical storage connector to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide an optical storage connector that can avoid incorrect insertion of positive and negative terminals, making it safer and more convenient to use.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a photoelectric storage connector for use as a positive or negative connector, comprising a socket and a plug. The socket includes a mounting base and a first conductive element disposed in the middle of the mounting base. One end of the mounting base is provided with a socket sleeve. The first conductive element is provided with a pin extending into the socket sleeve. The plug includes a plug socket and a second conductive element disposed within the plug socket. The plug socket is provided with a plug sleeve for engaging with the socket sleeve. The second conductive element is provided with a conductive sleeve extending into the plug sleeve. The pin engages with the conductive sleeve to form an electrical connection. The outer circular surface of the socket sleeve has a plurality of protrusions arranged in a circumferential array. The inner circular surface of the plug sleeve has a plurality of mating grooves, corresponding to the number of protrusions, for the corresponding protrusions to slide into. The number of protrusions when the photoelectric storage connector is used as a positive connector is different from the number of protrusions when the photoelectric storage connector is used as a negative connector.
[0006] By adopting the above technical solution, the number of protrusions and mating slots when the optical storage connector is used as a positive connector is different from that when it is used as a negative connector. This prevents the positive plug from mating with the negative socket or the negative plug from mating with the positive socket, thus avoiding incorrect positive and negative insertion. This makes the use safer and more convenient, and avoids situations where incorrect positive and negative insertion can cause the circuit to malfunction or damage to electrical equipment.
[0007] The present invention is further configured such that the socket sleeve includes a sleeve body and a detachable bushing mounted on the sleeve body, and the protrusion is disposed on the outer circular surface of the bushing.
[0008] By adopting the above technical solution, the socket sleeve body can be universally used. When the number of protrusions needs to be changed, only the bushing with a different number of protrusions needs to be replaced. It has good versatility and can significantly reduce production costs.
[0009] The present invention is further configured such that an annular groove is provided on the outer periphery of the sleeve body, and the upper end of the sleeve body corresponding to the annular groove serves as a limiting part, and a plurality of locking blocks for engaging into the annular groove are provided on the inner circular surface of the bushing.
[0010] By adopting the above technical solution, the sleeve body and the bushing are connected together by a snap-fit method, which not only makes the assembly operation very convenient, but also makes the connection structure firm and reliable.
[0011] The present invention is further configured such that the upper end of the outer circular surface of the limiting part is provided with a tapered guide surface, and the lower end of the card block is provided with a guide slope.
[0012] By adopting the above technical solution, during installation, the guide slope on the bushing block first engages with the tapered guide surface on the limiting part of the bushing body, and then the bushing is pressed down. Through tapered guidance deformation, the block passes over the limiting part and is engaged in the annular groove, making the engagement operation of the bushing and the bushing body easier and more convenient.
[0013] The present invention is further provided in that the limiting part of the sleeve body is provided with a plurality of vertically extending partition grooves along the circumferential direction.
[0014] By adopting the above technical solution and setting the partition groove, the limiting part can deform inward when squeezed, reducing the outer diameter, so that the locking block can more easily pass over the limiting part and lock into the annular groove.
[0015] The present invention is further configured such that a plurality of positioning blocks are arranged circumferentially on the inner circular surface of the bushing, the lower end of the positioning block abuts against the upper end of the limiting part, and the upper end of the locking block abuts against the upper end of the annular groove.
[0016] By adopting the above technical solution, the stability of the connection structure between the bushing and the sleeve body can be improved, and axial shaking can be avoided after the two are fitted together.
[0017] The present invention is further configured such that the upper end of the protrusion is provided with a tapered guide portion, and the lower end of the docking groove is provided with a flared opening.
[0018] By adopting the above technical solutions, the design of the tapered guide on the protrusion and the design of the flared groove greatly facilitate the operation of inserting the protrusion into the groove, making the operation of the two more convenient.
[0019] The present invention is further provided that the outer side of the tapered guide portion is provided with a guide slope that gradually tapers inward from bottom to top.
[0020] By adopting the above technical solution, the operation of inserting the protrusion into the docking groove is further facilitated.
[0021] The present invention is further provided that the plug socket is provided with a support sleeve for covering the outer periphery of the conductive sleeve, the outer circular surface of the support sleeve is in contact with the inner circular surface of the socket sleeve, and a sealing ring for forming a sealing fit with the inner circular surface of the socket sleeve is installed on the outer circular surface of the support sleeve.
[0022] By adopting the above technical solution, the support sleeve can support the conductive sleeve, and the design of the sealing ring on the support sleeve can prevent water from entering the optical storage connector, which could cause signal transmission interruption or instability.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Example: As attached Figures 1-7 The optical storage connector shown is used as a positive or negative connector, including a socket 1 and a plug 2. The socket 1 includes a mounting base 3 and a first conductive element 4 disposed in the middle of the mounting base 3. The first conductive element 4 is injection molded onto the mounting base 3. A socket sleeve 5 is integrally provided at one end of the mounting base 3. The first conductive element 4 is provided with a pin 6 extending into the socket sleeve 5. The plug 2 includes a plug socket 7 and a second conductive element 8 disposed within the plug socket 7. The second conductive element 8 is injection molded onto the plug socket 7. The plug socket 7 is integrally provided with... A plug sleeve 9 is provided for engaging with the socket sleeve 5. The second conductive member 8 has a conductive sleeve 10 that extends into the plug sleeve 9. The pin 6 engages with the conductive sleeve 10 to form an electrical connection. The outer surface of the socket sleeve 5 has a plurality of protrusions 11 arranged in a circumferential array. The inner surface of the plug sleeve 9 has a plurality of mating grooves 12, corresponding to the number of protrusions 11, for the corresponding protrusions 11 to slide into. The number of protrusions 11 when the optical storage connector is used as a positive connector differs from the number when it is used as a negative connector. This difference in the number of protrusions 11 and mating grooves 12 when the optical storage connector is used as a positive connector prevents the positive plug 2 from mating with the negative socket 1, or vice versa. This avoids incorrect positive or negative insertion, making it safer and more convenient to use, and preventing circuit malfunctions or damage to electrical equipment caused by incorrect positive or negative insertion.
[0033] In this embodiment, when the optical storage connector is used as the positive electrode connector, as shown in the attached... Figure 6 As shown, there are 12 protrusions 11 and 12 mating slots; when the optical storage connector is used as the negative connector, as shown in the attached diagram. Figure 7 As shown, there are 18 protrusions 11 and 18 mating grooves 12.
[0034] As attached Figure 2 and attached Figure 3As shown, the socket sleeve 5 includes a sleeve body 13 and a detachable bushing 14 mounted on the sleeve body 13. The outer circular surface of the bushing 14 is equivalent to the outer circular surface of the sleeve body 13, and the protrusion 11 is disposed on the outer circular surface of the bushing 14. This configuration allows the socket sleeve 5 body 13 to be universal; if the number of protrusions 11 needs to be changed, only the bushings 14 with different numbers of protrusions 11 need to be replaced. This provides good versatility and significantly reduces production costs.
[0035] Alternatively, the sleeve body 13 and the bushing 14 can also be an integral structure.
[0036] As attached Figure 2 and attached Figure 3 As shown, the outer periphery of the sleeve body 13 is provided with an annular groove 15, and the upper end of the sleeve body 13 corresponding to the annular groove 15 serves as a limiting part 16. The inner circular surface of the bushing 14 is provided with multiple locking blocks 17 for engaging with the annular groove 15. The sleeve body 13 and the bushing 14 are connected together by a snap-fit method, which not only makes the assembly operation very convenient, but also ensures a firm and reliable connection structure.
[0037] As attached Figure 2 and attached Figure 3 As shown, the upper end of the outer circular surface of the limiting part 16 is provided with a tapered guide surface 18 that is smaller at the top and larger at the bottom, and the lower end of the locking block 17 is provided with a guide slope 19. During installation, the guide slope 19 on the locking block 17 of the bushing 14 first engages with the tapered guide surface 18 on the limiting part 16 of the sleeve body 13, and then the bushing 14 is pressed down. Through tapered guided deformation, the locking block 17 passes over the limiting part 16 and is locked into the annular groove 15, making the engagement operation of the bushing 14 and the sleeve body 13 easier and more convenient.
[0038] As attached Figure 3 As shown, the limiting part 16 of the sleeve body 13 is provided with a plurality of vertically extending partition grooves 20 along the circumferential direction. The partition grooves 20 can be provided so that the limiting part 16 can deform inward when squeezed, reducing the outer diameter, so that the locking block 17 can more easily pass over the limiting part 16 and be locked into the annular groove 15.
[0039] As attached Figure 2 and attached Figure 3 As shown, multiple positioning blocks 21 are also arranged circumferentially on the inner circular surface of the bushing 14. The multiple positioning blocks 21 are distributed in a circumferential array. The lower end of the positioning block 21 abuts against the upper end of the limiting part 16, and the upper end of the locking block 17 abuts against the upper end of the annular groove 15. This design can improve the stability of the connection structure between the bushing 14 and the sleeve body 13 and avoid axial shaking after the two are engaged.
[0040] As attached Figures 1-4As shown, the upper end of the protrusion 11 is provided with a tapered guide portion 22, such as a triangle or an isosceles trapezoid, and the lower end of the mating groove 12 is provided with a flared opening 23 that is smaller inside and larger outside. The design of the tapered guide portion 22 on the protrusion 11 and the design of the flared opening 23 on the mating groove 12 greatly facilitates the operation of inserting the protrusion 11 into the mating groove 12, making the operation of the two more convenient.
[0041] As attached Figure 1 As shown, the outer side of the tapered guide portion 22 is provided with a guide slope 24 that gradually tapers inward from bottom to top. This design further facilitates the insertion of the protrusion 11 into the mating groove 12.
[0042] As attached Figure 5 As shown, the plug socket 7 is also provided with a support sleeve 25 for covering the outer periphery of the conductive sleeve 10. The outer circular surface of the support sleeve 25 fits against the inner circular surface of the socket sleeve 5, and a sealing ring 26 for forming a sealing fit with the inner circular surface of the socket sleeve 5 is installed on the outer circular surface of the support sleeve 25. Specifically, the outer circular surface of the support sleeve 25 has an annular sealing groove for positioning the sealing ring 26. The support sleeve 25 can support the conductive sleeve 10, and the design of the sealing ring 26 on the support sleeve 25 can prevent water from entering the optical storage connector, which could cause signal transmission interruption or instability.
