Description

Technical Field

[0001] The utility model relates to an improved structure of a waterproof quick connector for a switch device, and in particular to a combination of a connector module, an annular connector and an elastic water-blocking ring, which achieves a technology for quickly connecting a switch assembly (wiring) and an external conductor. Background Art

[0002] Switch devices used in motors, electronics, and automatic control equipment, and which can be assembled on operating panels, distribution boxes, or the like to connect wiring and circuits and / or, in conjunction with the operation of buttons and knobs, control the energization or de-energization of wiring circuits or wires, are already known in the art. For example, Taiwan Patents No. 102209861, "Waterproof Connector for Cables," and No. 109216290, "Waterproof Cable Connector," provide typical embodiments.

[0003] Conventional switchgear wiring and assembly practices, including the wiring modules of switchgear, usually have A contact assembly (or conductive terminal) protrudes from the rear end of the switch device (or switch body); the protruding contact assembly allows personnel to pair or weld external conductive wires (or cables) one by one according to usage requirements to form an electrical connection.

[0004] One of the structural and operational issues with the wiring of the switch device is that the individual pairing and soldering of external conductive wires (or cables) is time-consuming and cumbersome. During maintenance or replacement of the switch, personnel must individually desolder the wires and record the original matching positions of each contact assembly and each external wire. This is not only a cumbersome process, but also time-consuming and cumbersome, and does not improve operational efficiency.

[0005] In particular, although the above embodiment is equipped with a sealing ring (or water-stopping gasket), the tightness between the connector (or switch body) and the cable sleeve and the structural type between the cable connection conductive terminals (or contact components) still cannot achieve a reliable waterproof effect.

[0006] To improve the tightness (or waterproofing) of these components, prior art also discloses connector cable waterproof structures. These utilize a switch device (or switch body) in combination with an outer sleeve, a rubber sleeve, a tightening ring, and a sleeve to provide a tight seal between the cable (or cable) and the switch body, and to establish a form of electrical conductor module that allows personnel to connect the cable to the switch body. For example, Taiwan Patent No. 110145906, "Connector Cable Waterproof Sheathing Structure," provides a viable implementation.

[0007] One of the structural and practical issues with the above-mentioned embodiments is that the conventional switch body structure, which comprises an outer tube, a rubber sleeve, a tightening ring, and a sleeve, is complicated to assemble (and / or requires wiring to be matched one by one) due to the large number of mating components. Furthermore, the components are prone to loosening or detaching in the unlocked position (or loosely mated state).

[0008] In order to improve the situation where the components are loosened or separated, the old method also discloses that specific locking structures are respectively provided on the switch body, the outer cylinder and / or the sleeve cylinder to improve the situation where the components are loosened or separated.

[0009] However, as those skilled in the art are aware, providing specific locking structures on the switch body, outer cylinder, and / or sleeve cylinder not only complicates the structure and manufacturing / processing, but also reflects that each component has a specific structural type and cannot be shared or (repaired) interchanged with other switch devices (or switch components). This situation is not desirable.

[0010] Representatively, these references illustrate the use and structural design of conventional switchgear, connectors, and their associated components. Redesigning the switchgear and connector structures, taking into account the aforementioned application scenarios and adapting them to differ from conventional designs, could alter their usage and enhance their effectiveness, unlike conventional designs.

[0011] For example, taking into account the structure, the simplicity of operation, and the convenience of personnel in performing maintenance operations, the following topics should be included:

[0012] 1. Provide a connector structure that can achieve the function of quickly and stably connecting the switch device and facilitate personnel to release the connection between the quick connector and the switch device, improving the old method of pairing and plugging wires one by one, which is more troublesome and / or has a poor sealing effect between components.

[0013] 2. At the same time, without requiring a specific locking structure for the switch device and / or the mating components, the connection mechanism between the quick connector and the switch device can improve the connector structure in the prior art, which is complicated to assemble due to the large number of mating components and / or the components are prone to loosening (or detaching) in the unlocked position and / or improve the situation in the prior art where the components have a specific structural type and cannot be shared or (repaired) interchanged with other switch devices (or switch components).

[0014] However, these issues are not taught or specifically disclosed in the above-mentioned reference materials. Utility Model Content

DETAILED DESCRIPTION

[0027] See also Figure 1 、 2 and Figure 3 The improved waterproof quick connector structure for a switch device of the present invention includes a connector module and an annular connector assembly, generally indicated by reference numerals 80 and 10, respectively. The waterproof quick connector can be assembled with a switch device 90 to electrically connect the switch device 90 to an external conductive line to control the energization or de-energization of a wiring circuit or conductor.

[0028] The upper end (portion), lower end (portion), bottom end, left side, right side, front end (portion), rear end (portion), outside, inside, etc. mentioned in the following description are based on the directions shown in the drawings as reference directions.

[0029] The switch device 90 shown in the figure includes an operating portion 99 and a housing 98 (or outer shell) incorporating the operating portion 99. Housing 98 houses a conductive module and a contact assembly 96 protruding outward from the rear of housing 98, forming an electrical connection between the contact assembly 96 and the conductive module. Operating portion 99 can be a button, knob, or similar structure, allowing a person to press or rotate operating portion 99 to control the on / off state of switch device 90 (or the conductive module).

[0030] Basically, the switch device 90 is provided with an operating portion 99, a housing 98, a conductive module, a contact assembly 96 and other parts, which belong to the prior art and are therefore not described in detail.

[0031] In the embodiment adopted, at least one leading portion 97 and at least one limiting portion 92 are provided on the housing 98 of the switching device 90, which provide personnel with convenience in identifying and (guiding) operating the switching device 90 and the annular connector 10 to form a correct (position) combination.

[0032] Please refer to Figure 2、 3 and Figure 4 The annular connector 10 is an annular structure that can be assembled or sleeved on the housing 98 of the switch device 90. The annular connector 10 (the other end) is provided with a constricted portion 19; corresponding to the leading portion 97 and the limiting portion 92, the constricted portion 19 is provided with at least one guide groove 17.

[0033] Therefore, when the switch device 90 is combined with the annular coupler 10, a person can easily identify and operate the leading portion 97 and the restricting portion 92 to enter the guide groove 17. Furthermore, after rotating the annular coupler 10 (and / or the switch device 90), the restricting portion 92 is blocked by the constricted portion 19 and cannot be disengaged, thus achieving a combined (or positioning) effect.

[0034] The figure also shows that the annular coupling 10 has an outer wall 11 and an inner wall 12. The outer wall 11 of the annular coupling 10 may be provided with a marking 11a with words and / or patterns indicating unlocked and / or locked, and a circle of striped lines 11b to facilitate identification and operation of the annular coupling 10. Specifically, the marking 11a may indicate an unlocked position and a locked position.

[0035] In a feasible embodiment, the inner wall 12 of the annular connector 10 (adjacent to the lower end area of the necking portion 19) (or the right end area in the figure) is formed with a conical surface structure 13; the conical surface structure 13 is formed on the side of the necking portion 19 facing the inner wall 12. Figure 2 At least one stopper 14 is formed on the inner wall 12 of the annular coupler 10 (or the stopper 14 may be a flange structure and arranged at equal intervals). A combination portion 15 (with a threaded structure) is provided on the inner wall 12 of the annular coupler 10 (or between the lower end region adjacent to the conical structure 13 and the bottom end region of the inner wall 12). Furthermore, at least one positioning portion 18 is provided on the inner wall 12 of the annular coupler 10 in the region adjacent to the lower end of the combination portion 15. Positioning portion 18 may be a plate-like structure or a similar structure.

[0036] In the embodiment, the assembly portion 15 of the annular connector 10 is a structure using a double-thread (or multi-thread) structure; for example, a four-thread structure, so as to increase the speed at which personnel operate the annular connector 10 assembly joint module 80 .

[0037] The figure also depicts an elastic water-blocking ring 40, made of rubber, silicone, or a similar material, in a ring-shaped structure. The elastic water-blocking ring 40 comprises a head region 41 and a tail region 42 connected to the head region 41. At least a portion of the head region 41 forms an inwardly facing annular projection 43, while at least a portion of the tail region 42 forms an outwardly facing annular secondary projection 44. Therefore, the cross-sectional thickness of the annular projection 43 and the secondary projection 44 is greater than the cross-sectional thickness of the rest of the elastic water-blocking ring 40.

[0038] Figure 2 、 3 and Figure 4 The connector module 80 is connected to one end of the switch device 90 to form a ring-shaped secondary connector 60; the connector module 80 also includes a base 20, a covering 30, a wiring assembly 50 and a wire 85. The base 20 and the ring-shaped secondary connector 60 are integrally formed, and the wiring assembly 50 is disposed in the base 20; one end of the wiring assembly 50 and the base 20 together form a conductive slot 25 (indicated by the figure number). Figure 4 、 5 ), the other end of the wiring assembly 50 is electrically connected to the wire 85. The covering body 30 covers the base 20, so that at least a partial area of the wiring assembly 50 and the wire 85 forms a waterproof seal.

[0039] In the embodiment, the annular secondary connector 60 is made of plastic or a similar material, and has an annular structure and a secondary assembly portion 65. A neck portion 64 is formed on one side of the secondary assembly portion 65 of the annular secondary connector 60. The neck portion 64 defines an arcuate switching slot 66. A secondary positioning portion 68 is formed at each end of the arcuate switching slot 66, which defines an unlocked position and a locked position.

[0040] Therefore, the stopper 14 at one end of the inner wall 12 of the annular connector 10 and the positioning portion 18 on one side of the stopper 14 are matched to make the stopper 14 snap-fit with the neck 64, so that the annular connector 10 is pivotally mounted on the annular auxiliary connector 60; the positioning portion 18 is pivotally mounted in the arc-shaped switching groove 66 and can be positioned and rotated between the unlocked position and the locked position.

[0041] At the same time, when the annular connector 10 is combined with the annular sub-connector 60, the annular sub-connector 60 will not easily leave the annular connector 10, so that the annular connector 10 and the annular sub-connector 60 are still combined together to avoid the situation where the components are loosened (or separated).

[0042] The figure also shows that the annular sub-connector 60 has a circle of elastic blades 63 arranged at intervals, and the outer wall of one side of the elastic blades 63 has a sub-assembly portion 65; the sub-assembly portion 65 is formed with multiple threads. The elastic water-blocking ring 40 is accommodated in the annular sub-connector 60, and at least a part of the elastic water-blocking ring (40) is surrounded by the elastic blades 63 of the annular sub-connector 60. The annular connector 10 and the annular sub-connector 60 are assembled so that the conical structure 13 is adjacent to the elastic blades 63. In addition, a shoulder 67 is formed on the inner wall surface of one side of the elastic blades 63 of the annular sub-connector 60; an annular joint surface 69 is formed between the elastic blades 63 and the shoulder 67.

[0043] That is, a sub-assembly portion 65 (with a multi-thread structure) is formed on the outer wall of the annular sub-connector 60 (or the area between the elastic blades 63 and the neck 64), which is used to cause the conical surface structure 13 of the annular connector 10 to press the elastic blades 63 and the elastic water-blocking ring 40 when the sub-assembly portion 65 is assembled with the assembly portion 15 of the annular connector 10, thereby jointly tightening the switch device 90 (and / or the neck portion 19 of the annular connector 10 and the limiting portion 92 of the switch device 90 to form a tightened combination type), thereby achieving a stable and quick wiring effect, improving the wiring, assembly / maintenance troubles of the prior art or the need to apply a specific (or complex) structural combination fixation, etc.

[0044] In the embodiment employed, the structural configuration of the elastic blades 63 helps increase the (elastic) movement (or deformation) of the elastic blades 63 and / or reduces any obstruction between the elastic water-blocking ring 40 and the annular secondary connector 60. Furthermore, a shoulder 67 is provided on the inner edge of the annular secondary connector 60 for positioning or abutting against the tail region 42 of the elastic water-blocking ring 40. The shoulder 67 cooperates with the elastic blades 63 to accommodate the elastic water-blocking ring 40. Furthermore, at least a portion of the elastic water-blocking ring 40 (or the region between the head region 41 and the tail region 42) or the annular secondary protrusion 44 also forms a close (or tight) fit with the annular joint surface 69.

[0045] The figure also shows that the neck 64 of the annular secondary connector 60 forms two secondary positioning portions 68, so that the positioning portion 18 of the annular connector 10 moves and is locked (or engaged) between the two secondary positioning portions 68, thereby correspondingly forming an unlocking / locking mechanism.

[0046] In the embodiment adopted, the base 20 can accommodate the wiring assembly 50; one end of the wiring assembly 50 can clamp the contact assembly 96 of the switch device 90; the other end of the wiring assembly 50 extends from the bottom area of the base 20 for clamping or welding (external) wires 85.

[0047] Figure 4 The diagram depicts the structure of the annular secondary connector 60, which combines the elastic water-blocking ring 40 and the annular connector 10 (in the unlocked position). The elastic water-blocking ring 40 (or the annular secondary protrusion 44) is at least partially in contact with the annular joint surface 69 (and / or the annular protrusion 43 has not yet been deformed by external pressure), allowing the switch device 90 and the connector module 80 (and / or the annular connector 10) to be unlocked, disconnected, or inserted or removed.

[0048] The figure also shows that when the connector module 80 is assembled with the switch device 90, the leading portion 97 and the restricting portion 92 can pass through the guide groove 17 and the constricted portion 19, allowing the contact assembly 96 to be inserted into the conductive slot 25. At least one restricted space 91 is defined between the constricted portion 19, the elastic water-blocking ring 40, and the switch device 90. Furthermore, at least one accommodating space 93 is defined between the elastic water-blocking ring 40, the annular sub-connector 60, and the switch device 90, allowing the leading portion 97 to be accommodated in the accommodating space 93 and the restricting portion 92 to be accommodated in the restricted space 91. When the annular connector 10 is switched to the locked position, the restricting portion 92 is blocked by the constricted portion 19 and cannot escape from the restricted space 91.

[0049] See also Figure 4 、 5 When a person operates the annular coupler 10 (or the combination portion 15) to engage the annular sub-coupler 60 (or the sub-combination portion 65) or rotates the annular coupler 10 toward the locking position, the conical surface structure 13 of the annular coupler 10 presses the elastic blade 63 and the elastic water-blocking ring 40 (or the head region 41 and the annular protrusion 43) to produce a deformation movement, pressing the elastic blade 63 and the elastic water-blocking ring 40 (or the head region 41 and the annular protrusion 43) toward the switch device 90, while maintaining at least a partial area of the annular sub-protrusion 44 of the tail region 42. When the annular joint surface 69 is in contact with the elastic water-blocking ring 40 (or the head region 41 and the annular protrusion 43) responsive to the change between the unlocked position and the locked position, the elastic water-blocking ring 40 (or the head region 41 and the annular protrusion 43) is forced to form a loose fit and a tight fit with the housing 98 of the switch device 90. Furthermore, when the annular connector 10 is rotated to the locked position, the elastic water-blocking ring 40 (or the head region 41 and the annular protrusion 43) is pressed and sealed against the switch device 90 (or the housing 98), thereby effectively preventing the intrusion and accumulation of moisture, dust, or the like.

[0050] It should be noted that the annular connector 10 rotates relative to the annular sub-connector 60 to tighten the elastic water-blocking ring 40 to seal against the switch device 90 (or housing 98), and the friction force generated thereby prevents the switch device 90 and the annular sub-connector 60 (or other components) from separating. This eliminates the need for a specific locking structure to secure the connector module 80 (or the annular sub-connector 60) and the switch device 90.

[0051] It is understood that when personnel rotate the annular connector 10, the tight sealing effect between the annular connector 10, the elastic water-blocking ring 40, the annular auxiliary connector 60 and the switch device 90 can be released, thereby facilitating personnel to carry out loading, unloading and / or maintenance (replacement) operations.

[0052] Typically, this improved structure of waterproof quick connector for switchgear has the following considerations and advantages compared to the old method while meeting the requirements of easy operation:

[0053] 1. The annular connector 10, elastic water-blocking ring 40, connector module 80, and related mating structures have been redesigned. For example, the annular connector 10 features a conical structure 13, a stopper 14, a combination portion 15, and a positioning portion 18; the elastic water-blocking ring 40 includes a head region 41, an annular convex portion 43, a tail region 42, and an annular secondary convex portion 44; and the connector module 80 includes an annular secondary connector 60, which includes a secondary combination portion 65, a neck portion 64 with an arcuate switching groove 66, and a secondary positioning portion 68. Furthermore, the annular secondary connector 60 includes elastic blades 63, an annular joint surface 69, and other structural components. These components are significantly different from conventional designs and alter their use and operation, distinguishing them from the previous method.

[0054] 2. In particular, the waterproof joint structure composed of the annular connector 10, the elastic water-blocking ring 40, and the annular sub-connector 60 of the connector module 80 can obtain a connection mechanism for quickly and stably connecting (or rotating and tightening) the switch device 90, and also facilitates personnel to release the connection state between the quick connector and the switch device 90, thereby improving the old method of pairing and plugging wires one by one, which is cumbersome to operate and / or has a poor sealing effect between components; at the same time, under the premise that the switch device 90 and / or the mating components do not need to be provided with a specific locking structure, the rotational tightening operation between the improved waterproof quick connector structure and the switch device 90 completes their connection mechanism, and also improves the joint structure in the prior art, which has the problem of more mating components, being more cumbersome to assemble and / or each component being easily loosened (or detached) in the unlocked position, and / or improving the situation in the prior art where the components must be provided with a specific locking structure and cannot be shared or (repaired) interchanged with other switch devices (or switch components).

[0055] Therefore, the present invention provides an effective improved structure for a waterproof quick connector for a switch device. Its spatial configuration is different from the technical solutions in the prior art, and it has advantages that are unmatched by the prior art, showing considerable progress and fully meeting the requirements of a utility model patent.

[0056] However, the above description is only a feasible embodiment of the present invention and is not intended to limit the scope of the present invention. In other words, all equivalent changes and modifications made within the scope of the present invention are covered by the scope of the present invention.
