[0001] The utility model relates to the technical field of electrical equipment, in particular to a protective cover for a vertical terminal. Background Art

[0002] In the prior art, circuit boards are usually used in combination with connection terminals such as vertical terminals. However, there are gaps between multiple connection terminals (such as copper vertical terminals) arranged on the circuit board, so there is a high possibility that foreign objects fall into the gaps, causing a short circuit.

[0003] The solution to this problem in the prior art is usually to provide a long insulating cover to cover multiple wiring terminals arranged in the same row on the circuit board, thereby preventing foreign objects from falling in. However, the insulating cover still cannot completely prevent the problem of foreign objects falling in. Since space needs to be reserved on the wiring side of the wiring terminal to facilitate wiring operations, foreign objects usually fall from this side to between the terminals, causing an undesirable short circuit problem.

[0008] In a preferred embodiment, the elastic suspension member further includes a transition portion, which is located between the connecting portion and the suspension portion and is arranged between the side walls at an angle downward from the connecting portion, and the suspension portion is formed by hanging downward from the transition portion.

[0009] In a preferred embodiment, the connecting portion includes: a longitudinal rib, which is arranged longitudinally between a pair of the side walls; and a transverse top plate, which extends from the longitudinal rib to the side away from the crossbeam along a substantially horizontal direction between the pair of side walls to the transition portion.

[0010] In a preferred embodiment, the overhang portion is constructed to be roughly plate-shaped, and the overhang portion includes: an extension section, which extends downward from the transition portion and inwardly toward the accommodating cavity; and a guide section, which bends downward from the extension section and away from the accommodating cavity to form a free end that is roughly curved.

[0026] Now, an exemplary scheme of a protective cover for a vertical terminal according to the utility model is described in detail with reference to the accompanying drawings. The accompanying drawings are provided to present multiple embodiments of the utility model, but the accompanying drawings do not have to be drawn according to the dimensions of the specific embodiments, and certain features may be enlarged, removed or partially cut to better illustrate and explain the disclosure of the utility model. Some components in the accompanying drawings can be adjusted in position according to actual needs without affecting the technical effect. The phrase "in the accompanying drawings" or similar terms appearing in the specification do not necessarily refer to all drawings or examples.

[0027] definition:

[0028] The terms "first", "first", "second", "second" and the like in the present invention do not indicate any order, quantity or importance, but are used to distinguish one component from other components.

[0029] In this specification, the terms "inside", "outside", "lower", "bottom", "upper" and "top" refer to directions determined relative to a fully constructed and upright protective cover. Unless otherwise specified, the directional terms described in this specification are basically in accordance with the conventional directions understood by those skilled in the art.

[0030] With respect to structural terms, the terms “disposed” or “provided with” are used herein to indicate that one or more elements are located in a particular place or position as a macroscopic integral structure with other elements or as a separate element joined to another element.

[0031] As used herein, the term "connected" includes configurations in which an element is directly secured to another element by attaching it directly to the other element, as well as configurations in which an element is indirectly secured to another element by attaching it to an intermediate member which is in turn attached to the other element.

[0032] As used herein, the term "comprising" refers to various components, ingredients or steps that can be combined and applied in the process of implementing the present invention. Therefore, the term "comprising" is an open-ended term and includes the more restrictive terms "essentially consisting of..." and "consisting of..."

[0033] As used herein, the terms “substantially” or “approximately” mean that the referenced parameters or values ​​do not need to be achieved precisely, but deviations or variations (including, for example, tolerances, measurement errors, measurement precision limitations, and other factors known to those skilled in the art) may occur in an amount that does not interfere with the effect desired to be provided by the described features.

[0034] Figure 1 It is a schematic diagram of the protective cover 1 provided by the utility model being applied to the vertical terminal 2 on the circuit board 3; Figure 2 is from Figure 1 A three-dimensional view of the protective cover 1 observed from the side and rear, wherein the protective cover 1 is partially removed to show the vertical terminal 2.

[0035] like Figures 1 to 2As shown, there are shown a circuit board 3, a vertical terminal 2 arranged on the circuit board 3, and a protective cover 1 clamped on the circuit board 3 to cover the vertical terminal 2. The protective cover 1 can prevent foreign objects from falling into the vertical terminal 2 and causing unnecessary short circuit risks. Other additional components arranged on the circuit board 3 are not explained here.

[0036] from Figures 1 to 2 As can be seen in the figure, after the plurality of protective covers 1 cover the vertical terminals 2 respectively, the protective covers 1 of the adjacent vertical terminals 2 are close to each other so that foreign objects are prevented from falling therebetween. The protective cover 1 can be detachably fixed relative to the circuit board 3 to cover the vertical terminals 2 or expose them as needed.

[0037] Figure 3 1 is a three-dimensional diagram of the protective cover 1 provided by the present invention. The description of the direction of the vertical terminal 2 and the protective cover 1 mounted on the circuit board 3 is based on the orientation of the horizontally placed circuit board 3. Figure 3 As shown, the protective cover 1 includes a pair of side walls 10, an elastic suspension member 12 and a snap-fit ​​member 14. The pair of side walls 10 are arranged opposite to each other and are connected to each other through a crossbeam 16 arranged therebetween, so that the pair of side walls 10 and the crossbeam 16 jointly define a receiving cavity 100 (mainly defining the boundaries of the side and rear of the receiving cavity 100), and the receiving cavity 100 is roughly in a cube-like or rectangular shape for accommodating the vertical terminal 2. The protective cover 1 can be made into an integral structure through a molding process, but in order to facilitate the description of the specific structure of the protective cover 1, the protective cover 1 is divided into multiple parts for introduction so that those skilled in the art can better understand its structure.

[0038] See again Figure 3 The elastic suspension member 12 is between the pair of side walls 10 and a portion of it defines the top of the accommodating cavity 100. The elastic suspension member 12 has a first state and a second state. When the operator performs the operation of covering the vertical terminal 2, it is in the first state of deformation, and when the operator completes the covering operation, it is in the second state of deformation restoration. The specific changes and functions of the elastic suspension member 12 in different states will be described in detail below.

[0039] The engaging member 14 of the protective cover 1 is located at the lower part of the side wall 10. Specifically, a bottom plate 18 is arranged between the side walls 10 (see Figure 6 ), the engaging member 14 extends obliquely downward from the bottom plate 18 toward one side of the elastic suspension member 12, and then at least partially bends a hook at the free end of the engaging member 14. The hook is used to be caught under the circuit board 3 when the protective cover 1 completely covers the vertical terminal 2, so as to position the protective cover 1 relative to the circuit board 3.

[0040] Figure 4It is another three-dimensional diagram of the protective cover 1 provided by the utility model, such as Figure 4 As shown, the elastic suspension member 12 is arranged between a pair of side walls 10. Specifically, the elastic suspension member 12 includes a connecting portion 120, a hanging portion 122, and an optional transition portion 124. The connecting portion 120 is located between the pair of side walls 10 and connects the two. The connecting portion 120 is at a certain distance from the crossbeam 16 to reserve a space 120c for wiring to be introduced. After the wiring is introduced into the space 120c, it can be in close contact with the crossbeam 16 and the connecting portion 120 and basically fill this space 120c, thereby preventing foreign matter from entering therein and affecting the normal function of the vertical terminal 2.

[0041] The connection portion 120 is located at the front portion of the pair of side walls 10 (relative to the rear crossbeam 16). Specifically, the connection portion 120 is located at the upper portion of the accommodating cavity 100 (close to the top of the side wall 10) to separate the accommodating cavity 100 from the external environment, thereby shielding the vertical terminal 2 to be accommodated therein, thereby preventing foreign objects falling from above the vertical terminal 2 from affecting circuit safety.

[0042] The overhanging portion 122 hangs downward from the connecting portion 120, thereby defining the front of the accommodating cavity 100. The overhanging portion 122 has a first state in which it is deformed during the operation of covering the vertical terminal 2 and a second state in which it is deformed and reset after the covering operation is completed. In the first state, the operator can adopt an inclined orientation when putting the protective cover 1 on the vertical terminal 2, so that the overhanging portion 122 abuts against the front end of the side wall 10 of the vertical terminal 2 and deforms (expands outward to increase the space 120c of the accommodating cavity 100), while in the second state, the operator has covered the protective cover 1 on the vertical terminal 2 and the protective cover 1 has been installed in place in a vertical orientation. At this time, the overhanging portion 122 no longer abuts against the front end of the side wall 10 of the vertical terminal 2, but resets under the action of its own elasticity, and then the side of the overhanging portion 122 abuts against the side wall 10 of the vertical terminal 2, thereby clamping the vertical terminal 2 so that the protective cover 1 can be relatively firmly positioned on the vertical terminal 2.

[0043] See again Figure 2 Preferably, the vertical distance between the free end of the overhanging portion 122 and the surface of the circuit board 3 on which the vertical terminal 2 is installed is not greater than 0.5 mm. Such a distance setting can better prevent foreign matter from passing through the protective cover 1 into the space 120c where the vertical terminal 2 is located and affecting the normal function of the vertical terminal 2.

[0044] Preferably, the transition portion 124 can be located between the connecting portion 120 and the overhanging portion 122 to meet the structural design of the transition from the horizontal arrangement to the vertical arrangement of the elastic overhanging member 12. The transition portion 124 is arranged between the side walls 10 at an angle downward from the connecting portion 120, and the overhanging portion 122 is formed by hanging downward from the transition portion 124. The inclined design of the transition portion 124, on the one hand, helps the protective cover 1 to be demoulded after the molding process is completed, and on the other hand, it also avoids the structural change from horizontal to vertical between the connecting portion 120 and the overhanging portion 122 affecting the strength of the elastic overhanging member 12.

[0045] See again Figure 4 The engaging member 14 includes a first section 140 and a second section 142. The first section 140 is configured as a plate-shaped member (see Figure 5 ), which is formed by extending downwardly obliquely from the bottom plate 18 between a pair of side walls 10, and the second section 142 is located at the side end of the first section 140 and is formed by bending after extending along the longitudinal direction of the side wall 10 to a certain distance. The inclination angle of the first section 140 is preferably between 90° and 135°. The second section 142 includes a base and a hook, wherein the base is inclined like the first section 140, and the hook is bent forward from the base (i.e., close to the side of the overhanging portion 122) to position the protective cover 1 relative to the circuit board 3 after the protective cover 1 is covered on the vertical terminal 2. The hook is formed into a structure with a substantially rectangular notch (those skilled in the art can understand that other possible shapes of notches can also be selected by the present invention), that is, the side surface of the hook contacting the circuit board 3 is substantially parallel to the bottom surface of the side wall 10, so that the notch can match the shape and / or thickness of the circuit board 3 so that the protective cover 1 can be easily engaged with the circuit board 3. The depth of the hook (i.e., the distance from the front end of the hook of the second section 142 along the lateral direction of the side wall 10 where the hook is located to the base of the second section 142) is substantially equal to the deformation distance of the overhang 122. Such a design can simultaneously meet the requirements of the circuit board 3 being engaged and the overhang 122 being deformed (avoiding the vertical terminal 2).

[0046] Figure 5 is from Figure 4 A three-dimensional view of the protective cover 1 obtained by looking down from the top. Figure 5As shown, the connecting portion 120 includes a longitudinal rib 120a and a transverse top plate 120b, wherein the longitudinal rib 120a is arranged between a pair of side walls 10, and in the figure, it is roughly arranged along the longitudinal direction of the side wall 10 at the middle of the longitudinal direction of the side wall 10. The (optional) arrangement of the longitudinal rib 120a helps to improve the strength of the protective cover 1. The transverse top plate 120b is located between the pair of side walls 10 and on the side of the longitudinal rib 120a away from the crossbeam 16. As can be seen from the figure, the transverse top plate 120b (which blocks about half of the top space 120c) is spaced a certain distance from the crossbeam 16, and the remaining space 120c is used to introduce the wiring mentioned above.

[0047] Continue to see Figure 5 , the figure shows a protective cover 1, wherein the overhanging portion 122 of the protective cover 1 is constructed as a roughly plate-like structure. Specifically, the overhanging portion 122 includes an extension section 122a and a guide section 122b. Among them, the extension section 122a is a section extending downward from the transition section 124 and inwardly inclined toward the side of the accommodating cavity 100, while the guide section 122b is a section extending downward from the extension section 122a and bending outward toward the side away from the accommodating cavity 100. That is, the guide section 122b forms a structure with a roughly curved surface, and the guide section 122b also constitutes the free end of the overhanging portion 122. The setting of the guide section 122b, especially the design of its curved surface, is conducive to guiding the movement of the protective cover 1 when the protective cover 1 is sleeved on the vertical terminal 2 and is convenient for the shielding operation of the protective cover 1.

[0048] Figure 6 is from Figure 4 A three-dimensional view of the protective cover 1 observed from the rear. The figure shows a crossbeam 16 located between a pair of side walls 10, a bottom plate 18, and a snap-fitting member 14 extending from the bottom plate 18. Preferably, an opening 180 is also provided on the bottom plate 18, and the opening 180 can be used for a cable tie to pass through, and other required parts to be connected can be tied to the cable tie. Further optionally, a positioning flange is also provided between the side walls 10 along the longitudinal direction of the side wall 10 corresponding to the position of the crossbeam 16 (the positioning flange can also be regarded as extending from the bottom plate 18 along the longitudinal direction of the side wall 10 between the side walls 10), and the positioning flange has a groove, which can cooperate with the opening 180 on the bottom plate 18 for the cable tie to pass through, thereby limiting the position of the cable tie to avoid undesired movement of the cable tie.

[0049] The utility model provides a protective cover for a vertical terminal, which effectively and firmly covers the vertical terminal through the novel design of an elastic suspension piece and a clamping piece, and stably clamps relative to a circuit board. The elastic suspension piece also provides a top shield to prevent external foreign matter from falling into the vertical terminal and affecting the normal function of the vertical terminal during operation.
