Abstract
Description
Technical Field
[0001] This invention relates to the field of heavy-duty connector technology, and more specifically to a quick assembly structure for a heavy-duty connector adapter. Background Technology
[0002] Heavy-duty connectors are used as accessories for connecting electrical products and are widely used in equipment requiring electrical and signal connections, such as construction machinery, textile machinery, packaging and printing machinery, tobacco machinery, electric locomotives, and petrochemical electrical equipment. There are two types of cable exit methods for heavy-duty connectors: side exit and top exit. Due to the nature of the cable exit method, once determined, it cannot be changed. This means that multiple sets of molds are required to meet the needs of both operating conditions, resulting in high mold costs. The large amount of material required for the two types of cable exits also increases material management costs. Furthermore, this limits the customer's usage options.
[0003] Therefore, how to provide a heavy-duty connector adapter quick assembly structure that can flexibly adjust the two cable output methods is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0004] In view of this, the present invention provides a quick assembly structure for a heavy-duty connector adapter, which can change the cable outlet method (direction) according to installation needs. The product has strong versatility, can reduce production and use costs, and a single set of molds (shell + adapter cable outlet) can meet production and use needs, resulting in low investment costs.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a heavy-duty connector adapter quick assembly structure, comprising:
[0006] A heavy-duty connector housing, wherein the heavy-duty connector housing is provided with a connection port at an angle; The adapter cable outlet has through-type adapter interfaces and cable outlets on both sides. The adapter interface of the adapter cable outlet is rotatably engaged with the connection port and has multiple rotation restriction points in the circumferential direction. There is an angle between the cable outlet and the rotation axis of the adapter cable outlet. Based on the multiple rotation restriction points of the adapter cable outlet, the cable outlet has multiple cable outlet directions.
[0007] The beneficial technical effects of this invention are: the adapter cable outlet can be rotatably located at the connection port of the heavy-duty connector housing, and it has multiple rotation restriction points, providing installation conditions for different cable outlet forms. There is an angle between the cable outlet on the adapter cable outlet and the rotation direction of the adapter cable outlet. Thus, with multiple rotation restriction points on the adapter cable outlet, there will be multiple cable outlet directions to meet the connection and cable outlet needs of different devices, and the product has strong usability.
[0008] Preferably, the inner wall of the heavy-duty connector housing corresponding to the connection port is provided with an anti-rotation protrusion, and the inner side of the adapter cable outlet near the adapter port is provided with a wedge-shaped block. The anti-rotation protrusion is used to limit the rotation tendency of the wedge-shaped block. The outer side of the heavy-duty connector housing near the connection port is provided with a limiting groove, and the bottom of the adapter cable outlet near the adapter port is provided with a stop block. The limiting groove can engage the stop block and limit the continued rotation of the adapter cable outlet in the connection port. Based on the cooperation of the anti-rotation protrusion and the wedge-shaped block, as well as the cooperation of the stop block and the limiting groove, the adapter cable outlet can be rotatably positioned in the connection port of the heavy-duty connector housing.
[0009] The resulting technical effect is that the rotational positioning of the adapter cable outlet at the heavy-duty connector housing connection port is achieved based on two sets of mating structures. It can be understood that the mating of the anti-rotation protrusion and the wedge block, as well as the mating of the stop block and the limiting slot, restricts the positioning in both forward and reverse rotation, thereby achieving the rotational positioning of the adapter cable outlet. The rotational restriction point of the adapter cable outlet at the connection port is a prerequisite for ensuring the reliable setting of a specific cable outlet direction.
[0010] Preferably, there are two sets of anti-rotation protrusions arranged symmetrically on the two inner sidewalls of the connection port. The anti-rotation protrusions are provided with inclined surfaces and stop end faces. The wedge block is located inside the connection port and can rotate over the inclined surface. The wedge block can limit the rotation tendency under the action of the stop end face.
[0011] The resulting technical effect is that the anti-rotation protrusions are symmetrically arranged on the two inner side walls of the connection port, so as to achieve the same locking effect under different rotation points of the adapter cable head.
[0012] Preferably, it also includes a sealing ring, wherein the heavy-duty connector housing has an annular groove on the outer side wall corresponding to the connection port, and the sealing ring is disposed in the annular groove and can seal the inner side wall of the adapter.
[0013] The resulting technical effect is that the sealing ring can ensure a sealed connection between the connector and the adapter, thus providing a waterproof seal.
[0014] Preferably, the outer side wall of the heavy-duty connector housing corresponding to the connection port is provided with multiple protrusions, and the inner side wall of the adapter cable outlet corresponding to the adapter port is provided with a relief groove. The protrusion has a circumferential rotation stroke in the relief groove, and the middle of the side wall of the relief groove is provided with an anti-pull-out stop. When the adapter cable outlet rotates to the rotation restriction point, the anti-pull-out stop abuts against the protrusion and can restrict the adapter cable outlet from disengaging from the connection port.
[0015] The resulting technical effect is that, with the cooperation of the anti-pull-out stop, the protrusion can restrict the disconnection of the adapter cable head from the connector, the clearance groove can prevent the protrusion from entering, and the protrusion has a circumferential rotation stroke in the clearance groove. It can be understood that the rotating cable head is not continuously rotated 360 degrees at the connector, but is adjusted within a certain circumferential range. There are rotation restriction points for the adapter cable head within this rotation range.
[0016] Preferably, the connection port is inclined at 45 degrees on the top of the heavy-duty connector housing, and there is a 45-degree angle between the outlet and the rotation axis of the adapter outlet. The adapter outlet has a first rotation restriction point and a second rotation restriction point on the connection port of the heavy-duty connector housing. The first rotation restriction point and the second rotation restriction point are 180 degrees apart in the circumferential direction. The outlet of the adapter outlet has a side outlet state when it is at the first rotation restriction point, and the outlet of the adapter outlet has a top outlet state when it is at the second rotation restriction point.
[0017] The resulting technical effect is that the connection port is tilted at 45 degrees. Similarly, there is a 45-degree angle between the outlet and the rotation axis of the adapter outlet, which allows the adapter outlet to have two outlet methods: side outlet and top outlet, when the adapter outlet is at different rotation restriction points.
[0018] Preferably, the stop blocks are provided in two sets and have an L-shaped structure. The stop blocks are rotationally symmetrically arranged on the bottom periphery of the adapter cable head, and the limiting groove is L-shaped and adapted to the outer contour shape of the stop blocks.
[0019] The resulting technical effect is that the stop block, in conjunction with the limiting slot, limits the rotation angle of the adapter cable head when it rotates in the forward direction. It should be noted that the combination of the L-shaped stop block and the limiting slot also has the effect of resisting pull-out.
[0020] Preferably, both the heavy-duty connector housing and the adapter cable outlet are made of plastic.
[0021] The resulting technical advantage is that the heavy-duty plastic connector housing is suitable for scenarios requiring stable and reliable transmission of high current or high-power signals, such as large machinery, power systems, and rail transportation. Its biggest difference from ordinary connectors is its ability to withstand harsh environments such as high vibration, extreme temperatures, and electromagnetic interference, ensuring safe equipment operation.

Detailed Implementation
[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0025] See the appendix of this invention. Figures 1 to 8 According to an embodiment of the present invention, a heavy-duty connector adapter quick assembly structure includes: The heavy-duty connector housing 1 has a circular connection port 11 at a 45-degree angle on the top. The adapter cable outlet 2 has a through-type adapter interface 21 and a cable outlet 22 on both sides. The adapter interface 21 of the adapter cable outlet 2 is rotatably engaged with the connection port 11 and has two rotation restriction points in the circumferential direction. This is beneficial because when the connection port 11 of the heavy-duty connector housing 1 rotates, the adapter cable outlet 2 can restrict the rotation position at 180 degrees and at 360 degrees. It should be noted that this rotation engagement is not a continuous 360-degree circumferential rotation engagement, but a rotation engagement within a limited angle. There is an angle between the cable outlet 22 and the rotation axis of the adapter cable outlet 2, specifically an angle of 45 degrees. Based on the two rotation restriction points of the adapter cable outlet 2, the cable outlet 22 has two cable outlet methods: side outlet and top outlet.
[0026] In other embodiments, the inner wall of the heavy-duty connector housing 1 corresponding to the connection port 11 is provided with an anti-rotation protrusion 12, specifically a triangle. The adapter cable head 2 is provided with a wedge block 23 on the inner side near the adapter port 21. The wedge block 23 is arranged in an arc shape. In order to improve the fit between the connection port and the adapter port, an arc-shaped block plate is arranged on the circumferential path where the wedge block 23 is located. The outer wall of the arc-shaped block plate can fit tightly with the inner wall of the connection port. The anti-rotation protrusion 12 is used to limit the rotation tendency of the wedge block 23. The heavy-duty connector housing 1 has a limiting groove 13 on the outer side near the connection port 11, and the adapter cable head 2 has a stop block 24 near the bottom of the adapter port 21. The limiting groove 13 can engage the stop block 24 and restrict the adapter cable head 2 from continuing to rotate in the connection port. Based on the cooperation of the anti-rotation protrusion 12, the wedge block 23 and the stop block 24 and the limiting groove 13, the adapter cable head 2 can be positioned at the connection port of the heavy-duty connector housing 1 at the design point in the circumferential direction (both forward and reverse rotation directions are restricted).
[0027] In other embodiments, there are two sets of anti-rotation protrusions 12, which are rotationally symmetrically arranged on the two inner sidewalls of the connection port 11. The anti-rotation protrusions 12 are provided with inclined surfaces and stop end faces. The wedge block 23 is located inside the connection port 11 and can rotate over the inclined surface. Under the action of the stop end face, the wedge block 23 can limit the rotation tendency. It can be understood that the adapter cable outlet has the same snap-fit positioning effect whether it is in the side cable outlet installation state or the top cable outlet installation state.
[0028] To ensure sealing and waterproofing, a sealing ring 3 is also included. The outer wall of the heavy-duty connector housing 1 corresponding to the connection port 11 is provided with an annular groove 14. The sealing ring 3 is located in the annular groove 14 and can seal the inner wall of the connection adapter 21.
[0029] To improve the anti-detachment effect (pull-out resistance) of the adapter cable outlet, the outer wall of the heavy-duty connector housing 1 corresponding to the connection port 11 is provided with multiple protrusions 15. The protrusions are located below the sealing ring and will not affect the sealing connection effect between the adapter and the connection port. The inner wall of the adapter cable outlet 2 corresponding to the adapter port 21 is provided with a relief groove 211. The protrusions 15 have a circumferential rotation stroke in the relief groove 211, which prevents the adapter cable outlet from continuously rotating at the connection port. The middle of the side wall of the relief groove 211 is provided with an anti-pull-out stop 212. When the adapter cable outlet 2 rotates to the rotation limit point, the anti-pull-out stop 212 abuts against the protrusions 15 and can limit the detachment of the adapter cable outlet 2 from the connection port 11.
[0030] Specifically, the adapter cable outlet 2 has a first rotation restriction point and a second rotation restriction point on the connection port of the heavy-duty connector housing 1. The first rotation restriction point and the second rotation restriction point are 180 degrees apart in the circumferential direction. When the cable outlet of the adapter cable outlet 2 is at the first rotation restriction point, it has a side cable outlet state. (Refer to the attached document.) Figure 3In Embodiment 1, the outlet of the adapter 2 has a top-out state when it is at the second rotation restriction point, as shown in the attached figure. Figure 5 Example 2.
[0031] In some other embodiments, the stop block 24 is provided in two sets and has an L-shaped structure. The stop block 24 is rotate symmetrically disposed on the bottom periphery of the adapter cable head 2, and the limiting groove 13 is L-shaped and adapted to the outer contour shape of the stop block 24.
[0032] Both the heavy-duty connector housing 1 and the adapter cable outlet 2 are molded from plastic. It is used in scenarios requiring stable and reliable transmission of high current or high-power signals, such as large machinery, power systems, and rail transportation. Its biggest difference from ordinary connectors is its ability to withstand harsh environments such as high vibration, extreme temperatures, and electromagnetic interference, ensuring safe equipment operation.
[0033] When assembling and using the side-out cable configuration, first roughly rotate the adapter cable head to the designated installation angle area in the side-out cable direction, then press the adapter cable head into the connection port of the heavy-duty connector housing, and then rotate it slightly to assemble it into place. Refer to the attached document. Figure 4 .
[0034] When assembling and using the top-out cable method, first rotate the adapter cable head roughly to the designated installation angle area in the top-out cable direction, then press the adapter cable head into the connection port of the heavy-duty connector housing, and then rotate it slightly to assemble it into place. Refer to the attached document. Figure 6 .
[0035] This invention can significantly reduce mold costs by using an adapter for the cable outlet; it allows for free switching between side and top cable outlets during production assembly; and customers can switch the cable outlet direction themselves to meet usage requirements based on actual working conditions and with the available tools.
[0036] The apparatus and methods disclosed in the embodiments are described simply because they correspond to the methods disclosed in the embodiments. For relevant details, please refer to the method section.
