Description

Technical Field

[0001] The utility model relates to a protective shell, in particular to a core inserting protective shell which is convenient for use in a small space. Background Art

[0002] The ferrule, also known as the socket, is a conductive component used to connect the circuit board and the electronic component. The ferrule is generally composed of a socket body, a contact body and a pin. Signal transmission is carried out through the contact between the pin and the socket body. In order to prevent the ferrule from being affected by external conditions, such as dust, water, etc., a protective shell is usually set on the outside of the ferrule, especially at the connection between the two ferrules. In order to ensure the stability of the connection, a ferrule protective shell must be set.

[0003] The existing plug-in shell is divided into two structures, an upper shell and a lower shell, and the two shells are connected together by an external connection structure. However, in order to ensure the connection effect, the connection structure is often arranged more complicated, resulting in a larger size of the connection structure. However, this results in a large space occupied by the entire plug-in shell, and it cannot be used in some small spaces, which limits the use scenarios of the shell. In addition, the entire batch of shells also occupies a larger position during transportation, which is inconvenient to transport and greatly increases the cost of transportation.

[0004] Therefore, this case aims to provide a plug-in protective shell that is easy to use in a small space, and the connection structure of the upper shell and the lower shell will not exceed the range covered by the shell when they are locked together, so that the entire protective shell can fit tightly without occupying excess space. Utility Model Content

[0005] The utility model provides a plug-in protective housing which is convenient for use in a small space and can effectively solve the above-mentioned problem.

[0006] The utility model is achieved in this way:

[0007] A plug protection housing convenient for use in a small space, comprising: an upper shell and a lower shell for accommodating the plug, wherein the upper shell is provided with a side buckle structure for restraining the lower shell;

[0008] The side buckle structure includes a middle fulcrum riveted to the upper shell, a snap-on button is provided on the outer side of the lower shell, a fastening plate is hingedly mounted on the middle fulcrum, the fastening plate is fastened to the snap-on button when rotating, and the projection positions of the head and tail ends of the fastening plate do not exceed the two sides of the upper shell and the lower shell when rotating.

[0009] As a further improvement, the fastening plate is provided with a middle rotating block which cooperates with the snap-on button, the middle rotating block is eccentrically provided with an eccentric hole which cooperates with the snap-on button, a prying portion is integrally formed on the upper part of the middle rotating block, and a clamping portion which cooperates with the snap-on button is integrally formed on the lower part of the middle rotating block.

[0010] As a further improvement, an arc-shaped slot is provided on the middle rotating block, and a limit button fixedly connected to the outer side of the upper shell is provided at the upper end of the middle fulcrum. The limit button is located in the arc-shaped slot. When the fastening plate rotates, the arc-shaped slot is limited by the limit button.

[0011] As a further improvement, a square receiving bucket is provided on the inner side of the upper shell, and a square sheet is provided on the inner side of the lower shell. When the lower shell is matched with the upper shell, the square sheet of the lower shell is inserted into the receiving bucket of the upper shell.

[0012] As a further improvement, a first sealing strip is provided on the bottom side of the upper shell, and a second sealing strip is provided on the top of the lower shell. When the fastening piece clamps the clamping button, the first sealing strip and the second sealing strip squeeze each other.

[0013] The beneficial effects of the utility model are:

[0014] The existing clamping structures are all clamped and fixed by relatively bloated clamping structures, which not only expands the volume of the entire protective shell and reduces the applicable scope of the shell, but also increases the transportation cost. Therefore, the utility model adds a side buckle structure. First, it is arranged on the side of the entire upper shell and the lower shell, and does not directly expand the front and back areas of the upper shell and the lower shell, thereby reducing the space occupied by the shell. Secondly, during the operation, whether it is clamping the lower shell or loosening the lower shell, since the middle part is hinged on the middle fulcrum, the head and tail sides will not exceed the sides of the upper shell and the lower shell. Therefore, it can also be used when installed in some narrow spaces. As long as the entire upper shell and the lower shell can be placed in the installation space, the side buckle structure can be used normally.

[0015] When in use, the entire fastening piece is manually pried open by the prying part to make the clamping part and the clamping button clamp or loosen, so as to achieve the purpose of matching or loosening the upper shell and the lower shell. It can be operated even in a small space, just need to lift up or press down the prying part.

[0016] In order to prevent the bendable part from becoming loose during operation and to allow its movement to follow a certain trajectory and not exceed the areas on both sides of the upper shell and the lower shell after the movement, the utility model further provides an arc-shaped slot on the middle rotating block and a limit button on the upper shell. Therefore, during the operation of the bendable part, the entire side buckle structure actually moves within the area of ​​the arc-shaped slot, thereby limiting the range of movement of the side buckle structure, so that it will not occupy too much space during transportation due to lack of restraint.

[0017] The utility model is further provided with a accommodating bucket and a square sheet on the inner side of the upper shell and the lower shell, so that on the basis of the upper and lower side limitations of the upper shell and the lower shell by the side buckle structure, the upper shell and the lower shell are limited in the left and right directions by the accommodating bucket and the square sheet, thereby making the gap between the upper shell and the lower shell smaller, thereby improving the strength and waterproof effect of the entire outer shell.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0028] Reference Figure 1 to Figure 6 As shown, a plug-in protective shell that is convenient for use in a small space includes: an upper shell 10 and a lower shell 20 for accommodating the plug-in, the upper shell 10 is provided with a side buckle structure 30 for restraining the lower shell 20; the side buckle structure 30 includes a middle fulcrum 31 riveted to the upper shell 10, a snap button 33 is provided on the outer side of the lower shell 20, a fastening piece 34 is hingedly installed on the middle fulcrum 31, the fastening piece 34 is fastened to the snap button 33 when rotating, and the projection positions of the head and tail ends of the fastening piece 34 do not exceed the two sides of the upper shell 10 and the lower shell 20 when rotating.

[0029] In this embodiment, a round hole for the plug to be inserted is provided on the top of the upper shell 10, and a square hole for the socket to be inserted is provided on the bottom of the lower shell 20, so that the two can be docked within the entire shell, and the docking position is protected by the protective shell.

[0030] The existing clamping structures are all clamped and fixed by relatively bulky clamping structures, and most of them are arranged in a surrounding manner in the four directions of the outer shell. Although the same connection restriction effect can be achieved, it not only expands the volume of the entire protective outer shell and reduces the applicable scope of the outer shell, but also increases the transportation cost. Therefore, the present embodiment adds a side buckle structure 30. First, it is arranged on the side of the entire upper shell 10 and the lower shell 20, and does not directly expand the front and back areas of the upper shell 10 and the lower shell 20, thereby reducing the space occupied by the shell. Secondly, during the operation, whether it is clamping the lower shell 20 or loosening the lower shell 20, since the middle part is hinged on the middle fulcrum 31, the head and tail sides will not exceed the sides of the upper shell 10 and the lower shell 20, so it can also be used when installed in some narrow spaces. As long as the entire upper shell 10 and the lower shell 20 can be placed in the installation space, the side buckle structure 30 can be used normally.

[0031] As can be seen from the figure, in order to avoid excessive friction between the side buckle structure 30 and the upper shell 10 and the lower shell 20, a gasket is set on the inner side of the middle fulcrum 31, so as to prevent the fastening plate 34 from directly rubbing against the upper shell 10 and the lower shell 20 during rotation.

[0032] Specifically, the fastening piece 34 is provided with a middle rotating block 341 that cooperates with the snap button 33, and the middle rotating block 341 is eccentrically provided with an eccentric hole 3411 that cooperates with the snap button 33. The upper part of the middle rotating block 341 is integrally formed with a prying portion 342, and the lower part of the middle rotating block 341 is integrally formed with a clamping portion 343 that cooperates with the snap button 33. When in use, the entire fastening piece 34 is manually prying the prying portion 342 to allow the clamping portion 343 to be clamped or loosened with the snap button 33, thereby achieving the purpose of cooperating or loosening the upper shell 10 and the lower shell 20. It can be operated even in a small space by just lifting or pressing the prying portion 342.

[0033] The upper and lower parts of the upper and lower parts of the lower part of the lower part are fixed with the upper and lower parts of the lower part, so that the upper and lower parts of the lower part of the lower part of the lower part of the lower part of the lower part of the lower part of the lower part of the lower part of the lower part of the lower part of the lower part of the lower part of the lower part of the lower part.

[0034] On the inner side of the upper shell 10 and the lower shell 20, a square receiving bucket 11 is provided on the inner side of the upper shell 10 of the present embodiment, and a square sheet 21 is provided on the inner side of the lower shell 20. When the lower shell 20 is matched with the upper shell 10, the square sheet 21 of the lower shell 20 is inserted into the receiving bucket 11 of the upper shell 10. The receiving bucket 11 and the square sheet 21 are provided so that the upper shell 10 and the lower shell 20 are limited in the upper and lower sides by the side buckle structure 30. The receiving bucket 11 and the square sheet 21 are used to limit the upper shell 10 and the lower shell 20 in the left and right directions, thereby making the gap between the upper shell 10 and the lower shell 20 smaller, thereby improving the strength and waterproof effect of the entire outer shell.

[0035] In order to improve the sealing effect between the upper shell 10 and the lower shell 20, a first sealing strip is provided on the bottom side of the upper shell 10, and a second sealing strip is provided on the top of the lower shell 20. When the fastening plate 34 clamps the snap button 33, the first sealing strip and the second sealing strip are squeezed against each other, so that the sealing degree is higher when the upper shell 10 and the lower shell 20 are matched.

[0036] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
