Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment, and in particular to a connector. Background Art

[0002] As a conductive structure between two devices or systems, the connector plays an important role in the field of current transmission or signal transmission. For example, the connection between energy storage battery packs adopts a plug-in connection, which generally consists of two ends, usually one end is fixed on the battery pack mounting plate, and the other end is a floating end. The two ends are plugged together to realize the electrical connection of the battery pack.

[0003] In order to facilitate the connection, guide structures are usually processed separately on both sides of the plug, such as guide posts and guide holes, so as to reduce the possibility of misalignment between the two bodies when they are connected. However, the battery pack is heavy and cannot be installed completely vertically during assembly, resulting in collision force between the guide posts and the guide holes, which makes the guide posts easy to break, resulting in failure of the guide function. Summary of the invention

[0004] The purpose of the present invention is to provide a connector that solves the problem in the prior art that the battery pack is relatively heavy and cannot be installed completely vertically during assembly, resulting in collision force between the guide column and the guide hole when they are installed, and the guide column is easily broken, resulting in failure of the guide function.

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0006] A connector, comprising a first plug and a second plug. The first plug is used to connect to a first device, and the second plug is used to connect to a second device. The first plug comprises: a first body and a guide shell. The guide shell is arranged on the first body, and a female plug for mounting a male pin is arranged inside the guide shell. The second plug comprises: a second body and an assembly shell. The assembly shell is arranged on the second body and plugged with the guide shell, and a male plug for plugging with the female plug is arranged inside the assembly shell.

[0007] Optionally, the cross-sectional area of ​​the assembly shell is larger than that of the guide shell, and a guide gap for inserting the guide shell is formed between the inner side of the assembly shell and the male plug-in tube, and the inner side wall of the assembly shell is slidably fitted with the outer side wall of the guide shell.

[0008] Optionally, the outer side wall of the guide shell is provided with a guide inclined surface that slidably cooperates with the assembly shell.

[0009] Optionally, the outer side wall of the guide shell is provided with a plurality of grooves, and a guide rib is formed between two adjacent grooves.

[0010] Optionally, an inner side wall of the assembly shell is provided with an assembly inclined surface that is slidably matched with the guide shell.

[0011] Optionally, a sealing groove for installing a sealing ring is provided on the outer side wall of the guide shell, and the sealing ring abuts against the inner side wall of the assembly shell to seal a gap between the assembly shell and the guide shell.

[0012] Optionally, the first body is integrally formed with the female insert, and the second body is integrally formed with the male insert.

[0013] Optionally, the first ferrule can float relative to the first device within a set gap range, and the set gap is ±3.2 mm.

[0014] Beneficial effects of the present invention:

[0015] By setting the guide shell and the assembly shell, when the first device is connected to the second device, it is only necessary to make the first body correspond to the second body and plug the guide shell into the assembly shell. Under the guiding effect of the guide shell and the assembly shell, the first plug core can be plugged and matched with the second plug core. In this way, when the first plug core is plugged into the second plug core, the plugging is quickly completed by using the guiding relationship between the guide shell and the assembly shell. The guide shell and the assembly shell are respectively formed by the protruding extensions of the first body and the second body, so that the first plug core and the second plug core do not need to be provided with a separate guide structure, thereby effectively ensuring the guiding effect of the guide structure, reducing the possibility of failure of the guide function, and being conducive to ensuring the functional stability of the connector and extending the service life of the connector.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0026] An embodiment of the present invention provides a connector which does not require a separate guide structure, and can achieve plug-in mating of the plug core through the guidance of its own body, thereby reducing the overall volume of the connector and the material used. This can not only reduce the production cost of the connector, but also improve the utilization rate of the material.

[0027] Reference Figure 1 and Figure 2As shown, the connector includes a first ferrule 1 and a second ferrule 2. The first ferrule 1 is used to connect to a first device, and the second ferrule 2 is used to connect to a second device. The first ferrule 1 includes a first body 11 and a guide shell 12. The guide shell 12 is arranged on the first body 11, and a female plug 112 for mounting a male pin is arranged inside the guide shell 12. The second ferrule 2 includes a second body 21 and an assembly shell 22. The assembly shell 22 is arranged on the second body 21 and plugged with the guide shell 12, and a male plug 25 for plugging with the female plug 112 is arranged inside the assembly shell 22.

[0028] Specifically, the first ferrule 1 is connected to the first device through a plurality of fasteners, and can float relative to the first device so as to be aligned with the second ferrule 2. The guide shell 12 is formed by the first body 11 protruding and extending from the side away from the first device, and its cross section can be a polygon such as a rectangle, or a circular arc. One end of the female plug 112 passes through the first body 11 and extends into the guide shell 12, and the other end is located in the first device and is electrically connected to the circuit system in the first device.

[0029] The second ferrule 2 is fixedly connected to the second device through a plurality of fasteners, and an eccentric screw hole may be provided on the second ferrule 2 to prevent it from being installed upside down. The assembly shell 22 is formed by the second body 21 extending from one side away from the second device. The shape of the assembly shell 22 is designed according to the shape of the guide shell 12, and it can be guided and matched with the guide shell 12. The male plug 25 is arranged in the same manner as the female plug 112, and will not be described in detail here.

[0030] When the connector is used, the first ferrule 1 is first aligned with the second ferrule 2, and then the guide shell 12 is plugged into the assembly shell 22. Under the guiding effect of the guide shell 12 and the assembly shell 22, the first body 11 can be plugged and matched with the second body 21. In this way, when the first body 11 and the second body 21 are plugged, the plugging is quickly completed by using the guiding relationship between the guide shell 12 and the assembly shell 22. The guide shell 12 and the assembly shell 22 are respectively formed by the protrusions and extensions of the first body 11 and the second body 21, so that the first ferrule 1 and the second ferrule 2 do not need to be provided with a separate guide structure, thereby effectively ensuring the guiding effect of the guide structure, reducing the possibility of failure of the guide function, and being conducive to ensuring the functional stability of the connector and extending the service life of the connector.

[0031] Reference Figure 2 As shown, in some embodiments of the present invention, the cross-sectional area of ​​the assembly shell 22 is larger than the cross-sectional area of ​​the guide shell 12, and a guide gap 23 for inserting the guide shell 12 is formed between the inner side of the assembly shell 22 and the male plug-in tube 25, and the inner wall of the assembly shell 22 is slidably fitted with the outer wall of the guide shell 12.

[0032] Specifically, the cross-section of the assembly shell 22 and the cross-section of the guide shell 12 are both rectangular, and the length and width of the inner side of the assembly shell 22 are greater than the length and width of the outer side of the guide shell 12. The male plug 25 is located in the middle of the assembly shell 22, and the end face of the male plug 25 can be flush with the end face of the assembly shell 22, and a certain distance is maintained between the male plug 25 and the inner side wall of the assembly shell 22 to form the above-mentioned guide gap 23. The end face of the female plug 112 can also be flush with the end face of the guide shell 12, so that the guide shell 12 can be fully inserted into the assembly shell 22.

[0033] By forming the guide gap 23, when the female plug 112 is plugged into the male plug 25, the guide shell 12 is inserted into the guide gap 23 in the assembly shell 22, and the outer wall of the guide shell 12 slides and fits with the inner wall of the assembly shell 22, thereby generating a guiding effect. As the guide shell 12 is gradually inserted into the assembly shell 22, the female plug 112 can be smoothly plugged into the male plug 25.

[0034] Reference Figure 3 As shown, in some embodiments of the present invention, the outer side wall of the guide shell 12 is provided with a guide inclined surface 121 that is slidably matched with the assembly shell 22 .

[0035] Specifically, the opening end of the guide shell 12 is chamfered to form a guide slope 121, which is disposed toward the assembly shell 22. The inclination angle thereof can be designed according to the requirements of the plug-in fit, such as 45° or 30°.

[0036] By providing the guide slope 121, the cross-sectional area of ​​the end of the guide shell 12 inserted into the assembly shell 22 can be reduced, so as to facilitate the insertion of the guide shell 12 into the assembly shell 22. At the same time, the guide slope 121 can also play a guiding role. When the guide shell 12 and the assembly shell 22 are plugged in, the guide slope 121 can slide and fit with the inner side wall of the assembly shell 22, so that the guide shell 12 can slide smoothly into the assembly shell 22.

[0037] Reference Figure 3 As shown, in some embodiments of the present invention, a plurality of grooves are provided at intervals on the outer wall of the guide shell 12, and a guide convex rib 122 is formed between two adjacent grooves.

[0038] Specifically, the groove extends in the vertical direction, and the plurality of grooves are evenly spaced along the circumference of the guide shell 12 to form a plurality of guide ribs 122. The end of the guide rib 122 close to the guide inclined surface 121 can be connected to the guide inclined surface 121 and also provided with an inclined surface of a corresponding inclination angle. The guide rib 122 can also be fixed to the outer wall of the guide shell 12 by bonding or welding. In this case, an annular groove can be separately provided on the outer wall of the guide shell 12 for the installation of the guide rib 122.

[0039] By providing the groove, the material used for the guide shell 12 can be further reduced, and the formed guide rib 122 can effectively fill the gap of the guide shell 12 in the insertion guide gap 23, so that the guide shell 12 and the assembly shell 22 are stably plugged together and are not prone to shaking. At the same time, the provision of the guide rib 122 can also improve the strength of the guide shell 12 and reduce the possibility of damage to the guide shell 12 during the plugging process of the guide shell 12 and the assembly shell 22.

[0040] Reference Figure 4 As shown, in some embodiments of the present invention, the inner side wall of the assembly shell 22 is provided with an assembly inclined surface 221 that is slidably matched with the guide shell 12 .

[0041] Specifically, a chamfer is processed on the inner side wall of the assembly shell 22 to form an assembly bevel 221, and its inclination angle can be designed according to the guide bevel 121 of the guide shell 12, and the assembly bevel 221 can be matched with the guide bevel 121. By setting the assembly bevel 221, the opening area of ​​the assembly shell 22 is increased, which facilitates the smooth insertion of the guide shell 12 into the assembly shell 22. The assembly bevel 221 cooperates with the guide bevel 121, which can also play a role in limiting and guiding the insertion of the guide shell 12. As the guide bevel 121 fits with the assembly bevel 221, the guide shell 12 and the assembly shell 22 can be pushed to keep aligned, reducing the possibility of offset between the guide shell 12 and the assembly shell 22.

[0042] Reference Figure 3 As shown, in some embodiments of the present invention, a sealing groove 123 for installing a sealing ring (not shown in the figure) is provided on the outer wall of the guide shell 12, and the sealing ring abuts against the inner wall of the assembly shell 22 to seal the gap between the assembly shell 22 and the guide shell 12.

[0043] Specifically, the sealing groove 123 is arranged on the outer side wall of the guide shell 12, and is located below the guide rib 122. The sealing ring is glued into the sealing groove 123, and the sealing ring can be made of rubber, and one side of the sealing groove 123 protrudes to abut against the inner side wall of the assembly shell 22.

[0044] By providing the sealing ring, when the guide shell 12 is inserted into the assembly shell 22 , the sealing ring can effectively seal the gap between the guide shell 12 and the assembly shell 22 , thereby improving the sealing performance between the guide shell 12 and the assembly shell 22 .

[0045] In some embodiments of the present invention, the first body 11 and the female plug-in sleeve 112 are integrally formed, and the second body 21 and the male plug-in sleeve 25 are integrally formed.

[0046] Specifically, the first body 11 and the female plug 112 are integrally formed, that is, during the production process of the first ferrule 1, the first body 11 containing the female plug 112 is directly produced by injection molding or other methods. At this time, the position and installation direction of the female plug 112 in the first body 11 are determined, and then the pin connected with the wire is installed into the female plug 112, and a plug cover 113 is set at one end of the female plug 112 as the positive or negative pole of the first ferrule 1, and the production of the first ferrule 1 is completed. When the operator connects the first ferrule 1 to the first device, the direction and order of the female plug 112 are determined, so that the second ferrule 2 can be installed accordingly. The production method of the second ferrule 2 is the same as that of the first ferrule 1, which will not be repeated here.

[0047] By integrally forming the first body 11 and the female plug 112, and the second body 21 and the male plug 25, when installing the connector, it is only necessary to fix the first body 11 to complete the installation of the first plug 1. According to the installation direction and sequence of the first plug 1, the installation of the second plug 2 can be clearly determined, thereby effectively simplifying the installation process, reducing the difficulty of installation, and reducing the possibility of connector installation errors, so that the installation efficiency of the connector is significantly improved compared with the prior art.

[0048] Reference Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the first ferrule 1 can float relative to the first device within a set gap range, and the set gap is ±3.2 mm.

[0049] Specifically, since there is no need to separately set a guide structure on both sides of the ferrule, the available space of the first body 11 is increased, and a waist-shaped hole can be set on the first body 11 as a fixing hole for the fastener, and the length of the waist-shaped hole is ±3.2mm. Multiple waist-shaped holes are set along the circumference of the first body 11, so that the first body 11 can float within the range of ±3.2mm. Thereby, the first ferrule 1 and the second ferrule 2 can form an assembly and plug-in relationship within a larger tolerance range, which is conducive to improving the adaptability of the connector, increasing the applicable scenarios of the connector, and enabling the connector to be used in different environments. At the same time, the waist-shaped hole can also be an ordinary round hole.

[0050] In some embodiments of the present invention, the first body 11 and the second body 21 both include a plurality of power terminals 111. Specifically, a plurality of female plugs 112 may be provided in the first body 11 and the second body 21 as the power terminals 111, for example, two groups of parallel female plugs 112 are provided, an orange plug cover 113 is provided on the first group of female plugs 112 as the positive pole, and a black plug cover 113 is provided on the second group of female plugs 112 as the negative pole. In this way, the first body 11 can be connected to a plurality of power transmission terminals in the first device, and the second body 21 can be connected to a plurality of power transmission terminals in the second device, thereby effectively improving the adaptability of the connector.

[0051] Reference Figure 4 As shown, in some embodiments of the present invention, the second ferrule 2 has an eccentric mounting hole 24 for mounting a screw connected to the second device.

[0052] Specifically, the cross section of the second body 21 may be rectangular, and in this case, an eccentric mounting hole 24 is provided at the middle position of the left and right sides of the second body 21, and the connecting line of the two eccentric mounting holes 24 is not parallel to any side of the second body 21, so that the two eccentric mounting holes 24 are staggered. It should be understood that when the cross section of the second body 21 is other shapes, the position of the eccentric mounting hole 24 can be adjusted as long as the function of anti-reverse installation can be achieved, and this application does not make specific limitations.

[0053] By staggering the two eccentric mounting holes 24, when installing the second body 21, the two eccentric mounting holes 24 can be aligned with the corresponding threaded holes on the second device only when the second body 21 is installed in the correct installation direction. Otherwise, the eccentric mounting holes 24 cannot be aligned with the corresponding threaded holes on the second device, and installation cannot be performed. This can prevent the second body 21 from being installed upside down, allowing the operator to quickly determine the installation direction of the second body 21, further reducing the difficulty of installation.

[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
