Description

Technical Field

[0001] The utility model relates to the technical field of electronic connectors, in particular to a connector protection device. Background Art

[0002] With the rapid rise and promotion of new energy vehicles, various types of on-board chargers and on-board converter systems have gradually increased, and high-voltage connectors play an irreplaceable role. While the space requirements are becoming more and more stringent, people are also paying more and more attention to safety. High-voltage connectors have added high-voltage interlocking functions to prevent accidents and personal injuries. Due to space and cost considerations, high-voltage interlocking pins are often slender and fragile, and are easily damaged during transportation and use. Due to positioning and other issues, they are easily deformed and collapsed during assembly.

[0003] At present, the main problems of angled shielded connectors on the market are as follows: first, the pins and interlocking terminals are exposed, and the protective function of the protective structure is insufficient, so they are easily knocked crooked during transportation and placement; second, during the assembly process, the pins and interlocking terminals are not sufficiently guided, and the terminals are easily knocked crooked during the mating process, which leads to assembly difficulties and pin collapse.

[0004] Therefore, how to provide a connector protection device with a simple structure and good protection effect is a technical problem that technical personnel in this field currently need to solve. Utility Model Content

[0005] The utility model aims to provide a connector protection device which has a simple structure and can effectively protect the pins of the connector.

[0012] Preferably, both outer side walls of the first limiting portion of the protective sleeve are provided with guide protrusions along the axial direction thereof, and the plug-in interface of the female connector is provided with guide grooves for matching with the guide protrusions.

[0013] Preferably, the insertion interface of the female connector is provided with a chamfered structure to facilitate the insertion of the protective cover.

[0014] Preferably, a plurality of strip-shaped through holes are arranged on the side wall of the protective cover having the first clamping portion, and the strip-shaped through holes are used to increase the elasticity of the protective cover.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] In the description of the present invention, it should be understood that the terms "upper", "lower", "outer" and "inner" etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the position or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation of the present invention.

[0034] The utility model aims to provide a connector protection device which has a simple structure and can effectively protect the pins of the connector.

[0035] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0036] See also Figures 1 to 7 The present embodiment provides a connector protection device, comprising: a protective sleeve 200 sleeved on the interlocking plastic 110 of the male connector 100, the protective sleeve 200 is used to protect the pins installed on the interlocking plastic 110, a first clamping portion 210 is provided on the inner wall of the protective sleeve 200, the first clamping portion 210 is used to clamp with the second clamping portion 111 on the outer wall of the interlocking plastic 110, the protective sleeve 200 includes a first limiting portion 220 arranged along the direction of its axis, the first limiting portion 220 enables the pin to be slidably inserted into the limiting groove 310 in the plug-in interface of the female connector 300, and the sliding insertion direction of the first limiting portion 220 is parallel to the length extension direction of the pin.

[0037] Specifically, when the male connector 100 is connected to the female connector 300, the pins of the male connector 100 need to be inserted into the plug interface of the female connector 300, and the pins of the male connector 100 are fixed on the interlocking plastic 110; the present application provides a protective device, that is, a protective sleeve 200, and the protective sleeve 200 includes a first limiting portion 220 arranged along its axial direction. The protective sleeve 200 can be sleeved on the interlocking plastic 110, and the protective sleeve 200 is fixedly installed by clamping the first clamping portion 210 arranged on its inner wall with the second clamping portion 111 arranged on the interlocking plastic 110. When the protective sleeve 200 is sleeved on the interlocking plastic 110, the first limiting portion 220 will surround the pins. During transportation, the pins of the male connector 100 are easily knocked crooked due to their slender structure, but the setting of the first limiting portion 220 can effectively prevent this from happening. In this case, the pin is not easily touched before the first limiting portion 220 is damaged; in addition, the plug-in interface of the female connector 300 is relatively small, and the pin is not easily inserted into the plug-in interface of the female connector 300. Therefore, a limiting groove 310 that can cooperate with the first limiting portion 220 and engage with it is correspondingly provided in the plug-in interface of the female connector 300. In this way, when the male connector 100 needs to be plugged in, the pin connecting protective cover 200 can be inserted into the plug-in interface together. In this embodiment, the first limiting portion 220 will be inserted into the limiting groove 310 before the pin. When the first limiting portion 220 and the limiting groove 310 are engaged in place, the pin is naturally installed in place. Moreover, since the sliding insertion direction of the first limiting portion 220 is parallel to the length extension direction of the pin, this also effectively prevents the pin from bending during the insertion process. The first limiting portion 220 also has a guiding function.

[0038] Preferably, the first clamping portion 210 is a protruding structure, and the second clamping portion 111 is a groove that can cooperate with the first clamping portion 210 .

[0039] like Figure 2 , Figure 5 and Figure 6 As shown, in this embodiment, a protrusion structure is provided on the inner side wall of the protective cover 200, and correspondingly, a groove is provided on the outer side wall of the interlocking plastic 110, and the groove can be engaged with the protrusion, so that the protective cover 200 will not fall off after being upwardly sleeved on the interlocking plastic 110; it should be noted that in order to facilitate the sleeve of the protective cover 200, the upper end surface of the protrusion can be set at a certain inclination angle, as shown in FIG. Figure 6 As shown, the protective cover 200 can be put upwardly on the interlocking plastic 110 with less effort. Of course, the specific shape of the protrusion can be adjusted according to the actual situation as long as the expected requirements are met.

[0040] Preferably, the inner wall of the protective sleeve 200 is further provided with a third limiting portion 230 , which is used to engage with the fourth limiting portion 112 on the outer wall of the interlocking plastic 110 , and is used to limit the axial movement of the protective sleeve 200 along the interlocking plastic 110 .

[0041] It can be understood that in order to prevent the protective cover 200 from being too high on the interlocking plastic 110 during installation, causing the first limiting portion 220 to fail to protect the pins, a third limiting portion 230 is further provided on the inner wall of the protective cover 200, and a fourth limiting portion 112 is correspondingly provided on the outer wall of the interlocking plastic 110. The position of the fourth limiting portion 112 is exactly the position where the protective cover 200 is installed. In this way, when the protective cover 200 is installed in place, the third limiting portion 230 is engaged with the fourth limiting portion 112, thereby limiting the axial movement of the protective cover 200 along the interlocking plastic 110.

[0042] Preferably, the fourth limiting portion 112 is disposed at the end of the interlocking plastic 110 , and the fourth limiting portion 112 is specifically an angled structure or a step structure, and the third limiting portion 230 is specifically a protrusion that can cooperate with the fourth limiting portion 112 .

[0043] Specifically, Figure 5 and Figure 7 As shown, the fourth limiting portion 112 is preferably configured as an angled structure or a step structure, both of which have abutment surfaces, and the fourth limiting portion 112 is arranged at the end of the interlocking plastic 110 close to the pin, and the third limiting portion 230 is specifically a protruding structure that can abut against the angled structure or the step structure. With this configuration, in conjunction with the first clamping portion 210 and the second clamping portion 111, the protective cover 200 can be firmly installed on the interlocking plastic 110.

[0044] Preferably, the first limiting portion 220 is specifically two plate-like structures arranged opposite to each other at the ends of the protective cover 200 , and the edges and corners of the ends of the first limiting portion 220 away from the protective cover 200 are both provided with chamfered structures to facilitate the first limiting portion 220 to be inserted into the limiting groove 310 .

[0045] In this embodiment, if Figure 2 As shown, the female connector 300 has limit slots 310 on both sides of the plug interface. Correspondingly, the first limit portion 220 in this embodiment is specifically two plate-like structures arranged opposite to each other. Figure 4 and Figure 5 As shown, the first limiting portions 220 of the two plate-like structures are first inserted into the limiting grooves 310 when the male connector 100 is connected to the female connector 300 .

[0046] Furthermore, in order to facilitate the insertion of the first limiting portion 220, the corners of the end portion are as follows: Figure 4 and Figure 5 As shown, a chamfered structure is provided so that the end of the first limiting portion 220 is overall in a constricted shape. Such a configuration allows the first limiting portion 220 to be easily inserted into the limiting groove 310 .

[0047] Preferably, the protective sleeve 200 is provided with a first limiting portion 220 whose two outer side walls are both provided with guide protrusions 221 along the axial direction thereof, and the plug-in interface of the female connector 300 is provided with a guide groove 320 for matching with the guide protrusion 221 .

[0048] See also Figure 7 On the basis of the above embodiment, a strip-shaped guide protrusion 221 is further provided on the side wall of the protective cover 200, and the guide protrusion 221 is provided on the side wall where the first limiting portion 220 is located, so that the guide protrusion 221 can be extended as much as possible, and its guiding effect can be better played. At the same time, two guide grooves 320 are provided in the plug interface of the female connector 300. When the male connector 100 is connected to the female connector 300, the guide protrusion 221 will cooperate with the guide groove 320, and the two are slidably connected, which can further guide the pins.

[0049] Of course, the shape of the guide protrusion 221 can be adjusted according to actual conditions, and is not specifically limited herein. It is only necessary to ensure that the guide groove 320 is compatible with the guide protrusion 221 .

[0050] Preferably, the insertion interface of the female connector 300 is provided with a chamfered structure to facilitate the insertion of the protective cover 200 .

[0051] In addition, in order to further facilitate the insertion of the protective cover 200 and the pins into the upper opening of the plug interface of the female connector 300, a chamfered structure is provided around the periphery. This enlarges the plug interface of the female connector 300 and makes it easier to plug in the protective cover 200.

[0052] Preferably, the protective cover 200 is provided with a plurality of strip-shaped through holes 240 on the side wall of the first clamping portion 210 , and the strip-shaped through holes 240 are used to increase the elasticity of the protective cover 200 .

[0053] It is understandable that when the protective cover 200 is mounted on the interlocking plastic 110 , the protective cover 200 will be deformed due to the first clamping portion 210 . Therefore, in order to increase the elasticity of the protective cover 200 , a plurality of strip-shaped through holes 240 are provided on the side wall where the first clamping portion 210 is provided.

[0054] Preferably, the protective cover 200 is integrally formed by injection molding.

[0055] In this embodiment, the protective cover 200 is preferably integrally formed by injection molding of engineering plastics. Engineering plastics have good mechanical properties. In addition, integrally formed injection molding reduces the difficulty of manufacturing the protective cover 200 and reduces the production cost.

[0056] Preferably, the first clamping portion 210 is a groove structure, the second clamping portion 111 is a protrusion structure that can cooperate with the first clamping portion 210, the protective cover 200 is provided with a first limiting portion 220, and both outer walls thereof are provided with a second guide groove along its axial direction, and the plug-in interface of the female connector 300 is provided with a second guide protrusion for cooperating with the second guide groove.

[0057] In another embodiment, the first clamping portion 210 is set to a groove structure and the corresponding second clamping portion 111 is set to a protrusion structure. At the same time, the guide mechanism on the two side arms of the protective cover 200 is set to a second guide groove, and a second guide protrusion that can cooperate with the second guide groove is set in the plug-in interface of the female connector 300. In this way, the protective cover 200 can also be fixed and guided.

[0058] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0059] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
