[0038] The technical scheme of the utility model will be further described below with reference to the drawings and through specific embodiments.

[0039] As Figures 1 to 5 The utility model provides a connector, including shell 1, current pin 2 and signal pin 3, shell 1 includes current connecting portion, signal connecting portion and fixed mounting portion 13, current connecting portion is equipped with the first connecting hole 11 that can supply current pin 2 and insert, signal connecting portion is equipped with the second connecting hole 12 that can supply signal pin 3 and insert, current pin 2 and signal pin 3 are fixedly installed in shell 1, and the both ends of current pin 2 and signal pin 3 stretch out to the both ends of shell 1, fixed mounting portion 13 is used for fixing shell 1, when operating specifically, only need to make fixed mounting portion 13 align the one component that needs to be connected with, and make fixed mounting portion 13 and component fixed connection, can fix shell 1, current pin 2 and signal pin 3 are inserted in the corresponding connecting hole simultaneously, after the fixation of connector, another component that needs to be connected with connector, and the part of current pin 2 and signal pin 3 another end stretch out is inserted in another component, and simultaneously complete high voltage connection and signal connection of large current, simplify installation process, improve stability, and make the structure of connector more compact simultaneously.

[0040] As Figure 4 And Figure 5 Current pin 2 includes first connecting portion 21, second connecting portion 22 and first fixed portion 23, the width of first connecting portion 21 is greater than second connecting portion 22, first fixed portion 23 is arranged between first connecting portion 21 and second connecting portion 22, first fixed portion 23 is equipped with first clamping slot 24, and the protrusion that can be clamped into first clamping slot 24 is correspondingly arranged in first connecting hole 11, signal pin 3 includes third connecting portion 31, fourth connecting portion 32 and second fixed portion 33, the width of third connecting portion 31 is greater than fourth connecting portion 32, second fixed portion 33 is arranged between third connecting portion 31 and fourth connecting portion 32, second fixed portion 33 is equipped with second clamping slot 34, and the protrusion that can be clamped into second clamping slot 34 is correspondingly arranged in second connecting hole 12.In actual installation process, first connecting portion 21 of current pin 2 is inserted into shell 1 from the top of shell 1 along first connecting hole 11, and the protrusion in first connecting hole 11 is clamped into first clamping slot 24, since the width of first connecting portion 21 is greater than second connecting portion 22, current pin 2 cannot continue to move and is fixed in shell 1 at this time, the assembly of current pin 2 is completed, and similarly, signal pin 3 is inserted into shell 1 along second connecting hole 12 and is fixed, at this time, first connecting portion 21 and third connecting portion 31 are located at one end of the connector, and second connecting portion 22 and fourth connecting portion 32 are located at the other end of the connector, facilitating the connection of the connector with external elements.

[0041] For example, a first chamfer 25 is provided between the second connecting portion 22 and the first fixing portion 23. The wall of the first slot 24 near the second connecting portion 22 is perpendicular to the slot bottom. A second chamfer 35 is provided between the fourth connecting portion 32 and the second fixing portion 33. The wall of the second slot 34 near the fourth connecting portion 32 is perpendicular to the slot bottom. The first chamfer 25 can guide the protrusion in the first connecting hole 11 to snap into the first slot 24, making the installation process more labor-saving. At the same time, because the wall of the first slot 24 is perpendicular to the slot bottom, the protrusion in the first connecting hole 11 can only snap into the first slot 24 in one direction and cannot be separated from the first slot 24, preventing the current pin 2 from falling off. Similarly, the second chamfer 35 also serves as a guide, and the second slot 34 can also effectively prevent the signal pin 3 from falling off.

[0042] Furthermore, a plurality of first chamfers 25 are provided between the second connecting portion 22 and the first fixing portion 23, and a plurality of second chamfers 35 are provided between the fourth connecting portion 32 and the second fixing portion 33. Through the multi-level guidance of the plurality of chamfers, the resistance during the installation of the current pin 2 and the signal pin 3 can be reduced, thereby facilitating the assembly of the connector.

[0043] Exemplarily, the outer ends of the first connection portion 21 and the second connection portion 22 are both chamfered structures, and the outer ends of the third connection portion 31 and the fourth connection portion 32 are also chamfered structures, so as to facilitate plugging with external components.

[0044] like Figures 1-3 As shown, the fixed mounting portion 13 is symmetrically arranged on both sides of the housing 1. The fixed mounting portion 13 includes a pin 14 extending toward the bottom of the housing 1. A snap ring 15 is provided on the outer periphery of the pin 14. Both ends of the snap ring 15 are respectively provided with an inclined surface structure for guiding plugging and unplugging. A shrinkage groove 16 is provided in the middle of the pin 14 and passes through the snap ring 15. The snap ring 15 can ensure the stability of the installation connection and prevent the connector from falling off or loosening to cause poor contact. When the connector needs to be disassembled, the snap ring 15 passed through by the shrinkage groove 16 is squeezed close and finally detached from the installation position.

[0045] Exemplarily, a positioning groove 17 is provided on the top of the housing 1, and the positioning groove 17 is used to position the connector and the external connecting element. Furthermore, there are two positioning grooves 17, one of the two positioning grooves 17 is a circular structure, and the other of the two positioning grooves 17 is a waist-shaped structure, which can effectively prevent the connector from rotating and tilting, causing damage to the signal pin 3 and the current pin 2. At the same time, the waist-shaped structure enables it to avoid jamming caused by processing errors.

[0046] Exemplarily, the housing 1 is an integrated structure, and the housing 1 is made of insulating material. In this embodiment, the housing 1 is formed by injection molding. Furthermore, a hollow structure 18 is provided in the middle of the housing 1 to avoid deformation caused by structural stress concentration.

[0047] In addition, the above is only the preferred embodiment of the present application and the applied technical principle. The person skilled in the art can understand that the present application is not limited to the specific embodiments described herein, and various obvious changes, re-adjustments and substitutions can be made by the person skilled in the art without departing from the protection scope of the present application. Therefore, although the present application has been described in more detail through the above embodiments, the present application is not limited to the above embodiments, and more other equivalent embodiments can be included without departing from the concept of the present application, and the scope of the present application is determined by the scope of the appended claims.
