Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transportation tools, in particular to a joint protection shell and a vehicle thereof. Background Art
[0002] The connector protection shell is mainly used for the connection, fixation and protection of the vehicle circuit connector. The connector protection shell mainly places the connector in the chamber inside the shell through the snap-fitting effect between the shells, thereby protecting the connection of the connector. However, the existing connector protection shell is easy to fall out or be damaged in an environment where the vehicle vibrates frequently, resulting in snap-fit failure, and the connection and fixation effect of the connector cannot be guaranteed. Utility Model Content
[0003] Based on this, it is necessary to provide a connector protection shell and a vehicle thereof that can prevent buckle failure in a frequent vibration environment and is easy to install.
[0004] In order to solve the above technical problems, this application provides the following technical solutions:
[0005] A connector protective shell, comprising: a first shell; a second shell, which can be enclosed with the first shell to form a chamber for accommodating the connector, and the second shell is provided with a card window; a latch, which is installed on the first shell and can be inserted into the card window and snap-connected with the second shell; a spring sheet, which is provided on the second shell and located at the card window, and the spring sheet can deform relative to the second shell in response to an extrusion force; wherein, after the latch is inserted into the card window, the latch and the spring sheet abut against each other to limit the position.
[0006] It can be understood that, in the present application, a spring sheet is provided, and after the connector protection shell is snap-fitted with the latch and the window and in a vibration environment, the deformable ability of the spring sheet can, on the one hand, absorb vibrations to avoid snap-fit failure caused by breakage or extrusion of the latch; on the other hand, the deformation force provided by the spring sheet can always keep the latch and the second shell in a snap-fit state, thereby improving the stability of the snap-fit between the first shell and the second shell, thereby better protecting the connector located in the chamber.
[0007] In one of the embodiments, the spring sheet is arranged obliquely relative to the axis of the card window, and an insertion channel is formed between the spring sheet and the window wall of the card window; wherein the size of the insertion channel gradually decreases along the insertion direction of the latch.
[0008] It can be understood that by gradually reducing the size of the insertion channel, a larger inclined surface pressure can be formed, thereby increasing the snap-fitting force between the first shell and the second shell.
[0009] In one embodiment, the latch includes a main body and a protrusion, the protrusion is arranged on the side of one end of the main body, and the protrusion, the main body and the first shell together form a slot; after the latch is inserted into the card window, the edge of the card window is inserted into the card slot.
[0010] In one of the embodiments, an inclined surface is disposed on the convex portion, the inclined surface is inclined relative to the axis of the card window, and the inclined direction of the inclined surface is opposite to the inclined direction of the spring sheet.
[0011] It is understandable that the inclined surface on the protrusion can always abut against the edge of the first shell during the insertion of the tongue into the card window, thereby providing guidance for the movement of the second shell, making it easier to insert the tongue into the card window and achieving the snap connection between the tongue and the second shell.
[0012] In one of the embodiments, a limiting groove is further provided on the second shell, and the limiting groove is located at the window of the card window; after the card tongue is inserted into the card window, the protrusion is received in the limiting groove.
[0013] It can be understood that, through the provision of the limiting groove, after the latch tongue is buckled with the second shell, the latch tongue can be limited, thereby effectively improving the stability of the buckling between the latch tongue and the second shell.
[0014] In one embodiment, the latch tongue is integrally formed with the first shell; and / or the spring sheet is integrally formed with the second shell.
[0015] In one of the embodiments, the joint protection shell further includes a connecting block, which is disposed at the connection between the second shell and the spring sheet and is respectively connected to the second shell and the spring sheet.
[0016] It is understandable that the connection block is connected to the second shell and the spring sheet, and can resist the spring sheet when the spring sheet deforms relative to the second shell in response to the squeezing force caused by the vibration of the vehicle, thereby reducing the deformation range of the spring sheet, thereby increasing the pressure when the spring sheet deforms, and providing greater support for the buckling of the connector protection shell. At the same time, the connection block can also strengthen the structural strength of the spring sheet, thereby improving the reliability of the spring sheet abutting the tongue, and further improving the stability of the buckling.
[0017] In one embodiment, the connecting block, the second shell, and the spring are integrated into one piece.
[0018] In one embodiment, a void is provided on the first shell, and the void is communicated with the chamber.
[0019] It can be understood that the first shell is provided with a void so that when the environment in which the vehicle is located changes and generates pressure on the shell, the chamber of the protective shell in the buckled state can be kept at the same pressure as the external environment, thereby reducing the suction force between the first shell and the second shell when the joint protective shell is opened, thereby facilitating the disassembly and installation of the first shell and the second shell.
[0020] This application also provides the following technical solutions:
[0021] A vehicle comprises a connector and a connector protection shell as described in any one of the above embodiments, wherein the connector is accommodated in the connector protection shell.
[0022] It can be understood that the above-mentioned joint and joint protection shell are both used in the field of vehicle protection.
[0023] Compared with the prior art, the connector protection shell and the vehicle thereof are provided with a spring sheet. After the connector protection shell is buckled and connected with the latch tongue and the latch window and in a high-frequency vibration environment, the deformable ability of the spring sheet can absorb vibrations on the one hand to avoid buckling failure caused by breakage or extrusion of the latch tongue; on the other hand, the deformation force provided by the spring sheet can always keep the latch tongue and the second shell in a buckled state, thereby improving the buckling stability between the first shell and the second shell, thereby better protecting the connector located in the chamber.

The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.
[0036] See also Figures 1 to 4 The present application provides a connector protection shell 100, which is used in vehicles such as cars and motorcycles, and is mainly used to protect the connectors at the vehicle engine to prevent the wiring harness from being affected by the vibration of the engine and the vibration during the vehicle's driving, thereby causing the wiring harness to be separated from the engine and affecting the normal use of the vehicle. Of course, here, the connector protection shell 100 is not limited to being used at the connector of the engine, and it can also be used at the connection of other wiring harness connectors, which is not limited here.
[0037] like Figure 1 and Figure 2 As shown, the connector protective shell 100 includes a first shell 10, a second shell 20, a latch tongue 40 and a spring 50. The connector protective shell 100 mainly accommodates the connector through the chamber 30 enclosed by the first shell 10 and the second shell 20. A latch window 21 is provided on the second shell 20, and the latch tongue 40 is installed on the first shell 10, and can be inserted into the latch window 21 and snap-fitted with the second shell 20. The spring 50 is provided on the second shell 20 and located at the latch window 21, and the spring 50 can deform relative to the second shell 20 in response to the extrusion force. Among them, after the latch tongue 40 is inserted into the latch window 21, the latch tongue 40 and the spring 50 are abutted against each other for limiting. It should be explained that when the vehicle is driving in a high-frequency vibration environment, the connector protective shell 100 used to protect the connectors and other components arranged in the vehicle is prone to breakage or extrusion due to bumps, resulting in snap-fit failure, and the connectors and other components cannot be protected. In the present application, the connector protection shell 100 is provided with a spring piece 50. After the connector protection shell 100 is buckled and connected with the latch tongue 40 and the latch window 21 and in a vibration environment, the deformability of the spring piece 50 can absorb vibration on the one hand to avoid the buckling failure caused by the breakage or extrusion of the latch tongue 40; on the other hand, the deformation force provided by the spring piece 50 can always keep the latch tongue 40 and the second shell 20 in a buckled state, thereby improving the buckling stability between the first shell 10 and the second shell 20, thereby better protecting the connector and other components located in the chamber 30.
[0038] Furthermore, when the vehicle is running, the first shell 10 and the second shell 20 maintain a snap-fit connection state, at which time the tongue 40 is inserted into the window 21, and the spring piece 50 provided at the window 21 presses against the tongue 40, and the spring piece 50 reacts to the tongue 40 through the deformation generated by the squeezing force of the tongue 40, so that the contact surface between the spring piece 50 and the tongue 40 is stable and has no gap. When the vehicle is subjected to a high-frequency impact, the spring piece 50 can absorb part of the vibration and then produce a larger deformation to react to the tongue 40 through the squeezing force, so that the joint protective shell 100 always maintains a snap-fit state.
[0039] Preferably, the spring piece 50 is configured to be a high-toughness, wear-resistant and impact-resistant material such as polyamide plastic. In this embodiment, the spring piece 50 is configured to be PA66 material, which is the material with the highest mechanical strength and tensile strength among polyamide plastics, so that the spring piece 50 can absorb more vibrations and generate greater deformation force when the extrusion force of the tongue 40 increases in a high-frequency vibration environment.
[0040] In one embodiment, please refer to Figure 1 and Figure 4 , the first shell 10 is located at the upper end of the connector protective shell 100, the latch 40 is installed on the first shell 10, further, the latch 40 includes a main body 41 and a convex portion 42, the convex portion 42 is arranged on the side of one end of the main body 41, and a slot 13 is formed between the convex portion 42 and the main body 41; after the latch 40 is inserted into the card window 21, the edge of the card window 21 is snapped into the slot 13. It can be understood that the connection between the first shell 10 and the second shell 20 is connected by snapping the latch 40 and the card window 21, that is, the connection of the connector protective shell 100 is to clamp the second shell 20 through the slot 13 formed between the convex portion 42 of the latch 40 and the main body 41, so that the connector protective shell 100 remains in a snapped state.
[0041] Furthermore, an inclined surface 43 is provided on the convex portion 42, and the inclined surface 43 is inclined relative to the axis of the card window 21, and the inclined direction of the inclined surface 43 is opposite to the inclined direction of the spring piece 50. It can be understood that the inclined surface 43 on the convex portion 42 can always abut against the edge of the first shell 10 during the process of inserting the card tongue 40 into the card window 21, thereby providing a guide for the movement of the second shell 20, so as to make it easier to insert the card tongue 40 into the card window 21, and realize the buckling connection between the card tongue 40 and the second shell 20.
[0042] Preferably, the inclination of the inclined surface 43 corresponds to the thickness of the first shell 10. In this embodiment, the length of the right angle formed by the inclined surface 43 and the main body 41 is greater than 1 / 2 of the thickness of the first shell 10 and less than the thickness of the first shell 10, which can increase the contact area between the protrusion 42 and the second shell 20, thereby increasing the buckling force of the joint protection shell 100 during frequent vehicle vibrations, ensuring that the first shell 10 and the second shell 20 are always buckled.
[0043] like Figure 2 and Figure 3 As shown, the tongue 40 and the first shell 10 are provided as an integral body, and a void 12 is provided on the first shell 10, and the void 12 is communicated with the chamber 30. Specifically, the setting of the void 12 can keep the chamber 30 in the same pressure as the external environment in the buckled state when the environment in which the vehicle is located changes and produces pressure on the first shell 10 and / or the second shell 20, making it difficult to open the joint protection shell 100, thereby reducing the suction force between the first shell 10 and the second shell 20 when the joint protection shell 100 is opened, so as to facilitate the disassembly and installation between the first shell 10 and the second shell 20.
[0044] Here, the opening length of the avoidance 12 is smaller than the length of the side of the first shell 10 where the avoidance 12 is provided, so as to ensure the stability of the shell structure of the first shell 10 itself.
[0045] Please refer to Figure 3 The spring piece 50 is arranged obliquely relative to the axis of the card window 21, and the spring piece 50 and the window wall of the card window 21 form an insertion channel 22; wherein the size of the insertion channel 22 gradually decreases along the insertion direction of the latch 40. It can be understood that the spring piece 50 is arranged obliquely relative to the axis of the card window 21, and the size of the insertion channel 22 can be gradually reduced, so that a larger inclined pressure can be formed, thereby increasing the buckling force between the first shell 10 and the second shell 20.
[0046] Preferably, the inclination angle of the spring piece 50 relative to the axis of the card window is greater than 10 degrees and less than 80 degrees. In this embodiment, the inclination angle of the spring piece 50 relative to the axis of the card window is set to 60 degrees.
[0047] Please continue to refer to Figure 3 The second housing 20 is also provided with a limiting groove 23, which is located at the window of the card window 21. After the card tongue 40 is inserted into the card window 21, the protrusion 42 is received in the limiting groove 23. In the present application, by setting the limiting groove 23, after the card tongue 40 is buckled with the second housing 20, the card tongue 40 can be limited, thereby effectively improving the buckling stability of the card tongue 40 and the second housing 20.
[0048] like Figure 2 and Figure 3As shown, a connecting block 60 is also provided on the second shell 20, and the connecting block 60 is provided at the connection between the second shell 20 and the spring sheet 50, and is connected to the second shell 20 and the spring sheet 50. It can be understood that the connecting block 60 is connected to the second shell 20 and the spring sheet 50, and can resist the spring sheet 50 when the spring sheet 50 deforms relative to the second shell 20 in response to the extrusion force caused by the vibration of the vehicle, thereby reducing the range of deformation of the spring sheet 50, thereby increasing the pressure when the spring sheet 50 is deformed, and providing greater support for the buckling of the joint protective shell 100. At the same time, the connecting block 60 can also strengthen the structural strength of the spring sheet 50, thereby improving the reliability of the spring sheet 50 abutting the tongue 40, and further improving the stability of the buckling.
[0049] For further information, please refer to Figure 4 , the connecting block 60, the second shell 20 and the spring sheet 50 are arranged in an integrated manner. It can be understood that the deformation range of the integrated structure is relatively small, and when the first shell 10 and the second shell 20 are buckled, the squeezing force of the connecting block 60 on the spring sheet is increased, thereby increasing the buckling firmness of the joint protection shell, and simplifying the structure of the second shell 20, thereby reducing the production cost of the joint protection shell 100.
[0050] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0051] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several deformations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
