Description

Technical Field

[0001] The present invention relates to the technical field of new energy connectors, and in particular to a staggered stacked spring fork assembly. Background Art

[0002] The evolution of automobiles is clear. Since the beginning of the 20th century, there have been endless innovations and progress in the history of automobile development, which has made today's automobile connection technology quite mature and excellent. These progresses have always revolved around engine power and performance, safety, convenience in the driving space, driving quality, fuel source, on-board data relay and in-car entertainment. These data are inseparable from the continuous update of connectors, and high-voltage terminals and connectors are also required to ensure the safety, stability and reliability of data transmission and power transmission between batteries and other voltage devices. Such requirements for current transmission require many contact points to increase the current capacity of the circuit. In addition, the environment in which vehicles are used is becoming more and more harsh, and the standard requirements for connectors are becoming higher and higher. Connectors will be subject to vibration and wear over time. The spring cantilever structure of the terminal may fail, thereby reducing the stability of the entire vehicle system. Therefore, a flexible plug-in and pull-out force is currently needed, but a reliable contact surface, number or contact positive pressure is required. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned background technology and provide a staggered stacking spring fork assembly that can be combined for both small current and large current connectors. It can be suitable for connectors for the whole vehicle system of new energy electric vehicles. It is not only simple to process and assemble, but also has reliable connection performance.

[0004] In order to achieve the above technical effects, the present invention adopts the following technical solutions:

[0005] A dislocated superimposed spring fork assembly, comprising a male terminal, a dislocated superimposed spring sheet assembly, a transfer terminal and a spring sheet connector; the dislocated superimposed spring sheet assembly is composed of a plurality of single-piece spring forks, the appearance of the single-piece spring fork is H-shaped and includes four contact line ends, each contact line end is provided with a spring fork contact, and the two spring fork contacts located at the same end of the single-piece spring fork are arranged opposite to each other, and the spring fork contact adopts a rounded corner design with a smooth transition; the two ends of the dislocated superimposed spring fork assembly are respectively an input power end plugged into the male terminal and an output power end plugged into the transfer terminal, and a plurality of single-piece spring forks are arranged in parallel according to a certain rule and connected through a spring sheet connector, and the spring fork contacts at the same end of two adjacent single-piece spring forks are dislocated with each other; the staggered spring fork contacts can, on the one hand, avoid resonance in harsh vibration environments such as high speed and long-term operation working environments, causing the contact contact to fail to contact with the corresponding terminal, thereby causing a short-term instantaneous disconnection; on the other hand, the positive contact pressure can be reduced to make the plugging and unplugging softer;

[0006] When in use, the current is introduced from the male terminal, and the male terminal is plugged into the power input end of the offset stacked spring clip assembly. After the current flows through the offset stacked spring clip assembly, it flows out from the adapter terminal plugged into the power output end of the offset stacked spring clip assembly. In specific applications, the number of single-piece spring forks stacked in the offset stacked spring clip assembly can be set according to the size of the current flowing through. The more single-piece spring forks are stacked, the greater the overcurrent capacity of the stacked spring clip assembly, and vice versa. Therefore, by adjusting the number of stacked single-piece spring forks, different current level conditions can be met. At the same time, in the offset stacked spring fork assembly of the present invention, a number of staggered elastic contact points (i.e., spring fork contacts) are provided at the power input end and the power output end of the offset stacked spring clip assembly to form an insertion interface that is respectively plugged with the male terminal and the adapter terminal. Not only can flexible contact be achieved and the insertion and removal force be reduced, but even under harsh vibration conditions, the resonance of the elastic contact points can be avoided to cause instantaneous disconnection caused by contact failure, thereby ensuring the stability and safety of the connection.

[0007] Furthermore, the four contact line ends of the single-piece spring fork are connected through the main board, and the four contact line ends are respectively the upper left spring fork, the upper right spring fork, the lower right spring fork and the lower left spring fork in a clockwise direction from the first contact line end on the left side of the main board. The socket between the upper left spring fork and the lower left spring fork constitutes the slot at the left end of the single-piece spring fork, and the socket between the upper right spring fork and the lower right spring fork constitutes the slot at the right end of the single-piece spring fork.

[0008] Furthermore, the upper left spring fork has the same length as the upper right spring fork, the lower right spring fork has the same length as the lower left spring fork, the upper left spring fork has a different length from the lower left spring fork, and the staggered superimposed spring sheet assembly is formed by stacking a number of single-piece spring forks in a positive and negative overlapping manner.

[0009] Furthermore, the upper left spring fork has the same length as the lower left spring fork, the upper right spring fork has the same length as the lower right spring fork, the upper left spring fork has a different length from the upper right spring fork, and the staggered superimposed spring sheet assembly is formed by stacking a number of single-piece spring forks in a positive and negative overlapping manner.

[0010] Furthermore, the single-piece spring fork is divided into a first single-piece spring fork and a second single-piece spring fork, the upper left spring fork, the upper right spring fork, the lower right spring fork and the lower left spring fork of the first single-piece spring fork are all the same length, the upper left spring fork of the second single-piece spring fork is the same length as the lower left spring fork, the upper right spring fork is the same length as the lower right spring fork, and the upper left spring fork is different in length from the upper right spring fork, or the upper left spring fork of the second single-piece spring fork is the same length as the upper right spring fork, the lower right spring fork is the same length as the lower left spring fork, and the upper left spring fork is different in length from the lower left spring fork, and the staggered superimposed spring sheet assembly is formed by the first single-piece spring fork and the second single-piece spring fork being stacked at intervals, and a second single-piece spring fork is provided between two adjacent first single-piece spring forks.

[0011] Furthermore, the spring connecting piece is a pin shaft, and a pin hole cooperating with the pin shaft is provided on the main plate of the single-piece spring fork. Then, by inserting the pin shaft into the pin holes of several single-piece spring forks arranged in parallel, several single-piece spring forks can be connected. Through the connection method between the pin shaft and the pin hole, each single-piece spring fork can have a suitable size tolerance. After the male terminal is inserted, it can meet the use requirements within the tolerance and have better operating comfort.

[0012] Furthermore, the spring connecting piece is a connecting plate, and a plurality of buckles are arranged in parallel on the connecting plate. The upper and lower sides of the single-piece spring fork are provided with matching slots. A plurality of single-piece spring forks are connected between the two connecting plates, that is, by plugging a plurality of single-piece spring forks into the connecting plates respectively, a plurality of single-piece spring forks are finally arranged in parallel. The connecting plate and the single-piece spring fork are connected by buckle slots, so that each single-piece spring fork is matched with the connecting plate respectively, and the rotation of the single-piece spring fork can be limited within a certain range of rotation.

[0013] Furthermore, the spring fork contact is formed by a bending process, and the single-piece spring fork is formed by a stamping process. The spring fork contact of this solution is arranged on the non-punching surface of the single-piece spring fork, and a transitionally smooth fillet is directly formed by a bending process, which can make it smoother when plugging with the corresponding terminal. The single-piece spring fork is formed by a stamping process, which is conducive to further ensuring the consistency of part size and high production efficiency.

[0014] Furthermore, the end face shape of one end of the adapter terminal that is plugged into the offset stacking spring sheet assembly is wavy. When the positive pressure of the single-piece spring fork is constant, the contact timing of the adapter terminal that cooperates with the offset stacking spring sheet assembly and the single single-piece spring fork can be changed, so that the number of effective contact pieces is reduced during the insertion process, thereby changing the resultant force of the positive pressure, thereby further ensuring flexible plugging and unplugging with the offset stacking spring sheet assembly.

[0015] Furthermore, the adapter terminal is also connected to a cable, and the cable and the adapter terminal are crimped or welded. In practice, other suitable cable connection methods can also be selected according to specific circumstances. The adapter terminal can meet the wiring methods at different angles, meeting the requirements of new energy electric vehicles for compact space layout of different vehicles.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0018] At the same time, each single-piece spring fork of the staggered superimposed spring fork assembly of the present invention is provided with four contact points, and multiple single-piece spring forks are arranged in parallel to form line contact, which can ensure the reliability of contact; and the contact points of the staggered superimposed spring sheet assembly of the present invention and the contact ends of the male terminal and the adapter terminal are staggered and overlapped, which can effectively avoid resonance during long-term operation and has the advantage of high anti-vibration strength. At the same time, its spring fork contact adopts a rounded corner design with a smooth transition, which can effectively improve the softness during insertion, and its adapter terminal can meet the line outlet methods of different angles, meeting the requirements of new energy electric vehicles for compact space layout of different vehicles, and has the advantages of being able to combine different current sizes, soft plugging and unplugging, high anti-vibration strength, and high manufacturability, and can be suitable for automated assembly to improve assembly efficiency.

DETAILED DESCRIPTION

[0029] The present invention will be further described and illustrated below in conjunction with the embodiments of the present invention.

[0030] Example:

[0031] Embodiment 1:

[0032] like Figure 1 As shown, a staggered stacked spring fork assembly includes a male terminal 1, a staggered stacked spring sheet assembly 2, a transfer terminal 3 and a spring sheet connector 4.

[0033] Specifically, Figure 2 and Figure 3 As shown, the offset superimposed spring element assembly 2 is composed of a plurality of single-piece spring forks 5. The appearance of the single-piece spring fork 5 is H-shaped and includes four contact line ends. A spring fork contact 56 is provided at the end of each contact line end. The two spring fork contacts 56 located at the same end of the single-piece spring fork 5 are arranged opposite to each other, and the spring fork contact 56 adopts a rounded corner design with a smooth transition.

[0034] The two ends of the staggered superimposed spring fork assembly 2 are respectively the power input end plugged into the male terminal 1 and the power output end plugged into the adapter terminal 3. A plurality of single-piece spring forks 5 are arranged in parallel according to a certain rule and connected by the spring fork connector 4, and the spring fork contacts 56 at the same end of two adjacent single-piece spring forks 5 are staggered with each other. In this embodiment, the staggered spring fork contacts 56 have the following beneficial effects: first, it can avoid the resonance of the staggered superimposed spring fork assembly in a harsh vibration environment such as high speed and a long-term operation working environment, causing the contact contact to fail to contact with the corresponding terminal, thereby causing a short-term instantaneous disconnection; secondly, it can also reduce the positive contact pressure to make the plugging and unplugging more gentle.

[0035] Specifically, in this embodiment, Figure 3As shown, the four contact line ends of the single-piece spring fork 5 are connected through the main board 55 (the main board 55 and the four contact lines are integrally formed), and the four contact line ends are respectively the upper left spring fork 51, the upper right spring fork 52, the lower right spring fork 53 and the lower left spring fork 54 in a clockwise direction from the first contact line end on the left side of the main board 55. The socket between the upper left spring fork 51 and the lower left spring fork 54 constitutes the slot at the left end of the single-piece spring fork 5, and the socket between the upper right spring fork 52 and the lower right spring fork 53 constitutes the slot at the right end of the single-piece spring fork 5. Among them, the upper left spring fork 51 and the lower left spring fork 54 have the same length, the upper right spring fork 52 and the lower right spring fork 53 have the same length, and the upper left spring fork 51 and the upper right spring fork 52 have different lengths, and specifically, the length of the upper left spring fork 51 is less than the length of the upper right spring fork 52. The offset superposition spring sheet assembly 2 is formed by stacking a number of single-piece spring forks 5 in a positive and negative overlapping manner.

[0036] At the same time, in the present embodiment, the spring connector 4 is a pin shaft, and a pin hole 57 cooperating with the pin shaft is provided on the main board 55 of the single-piece spring fork 5. Then, by inserting the pin shaft into the pin holes 57 of several single-piece spring forks 5 arranged in parallel, several single-piece spring forks 5 can be connected. Through the connection method between the pin shaft and the pin hole 57, each single-piece spring fork 5 can have a suitable size tolerance. After the male terminal 1 is inserted, it can meet the use requirements within the tolerance and also have better operating comfort.

[0037] Specifically, the spring fork contact 56 is formed by a bending process, and the single-piece spring fork 5 is formed by a stamping process. The spring fork contact 56 in this embodiment is arranged on the non-punched surface of the single-piece spring fork 5, and the bending process is directly used to form a smooth rounded corner, which can make it smoother when plugging with the corresponding terminal. The single-piece spring fork 5 is formed by a stamping process, which is beneficial to further ensure the consistency of part size and high production efficiency.

[0038] Preferably, in this embodiment, the single-piece spring fork 5 is made of copper material with high conductivity. After multiple insertions and extractions for simulation analysis, the single-piece spring fork 5 does not yield and can still achieve a good contact resistance.

[0039] Preferably, the end face shape of one end of the adapter terminal 3 that is plugged into the offset stacking spring clip assembly 2 is wavy. When the positive pressure of the single-piece spring fork 5 is constant, the contact timing of the adapter terminal 3 that cooperates with the offset stacking spring clip assembly 2 and the single single-piece spring fork 5 can be changed, so that the number of effective contact pieces is reduced during the insertion process, thereby changing the resultant force of the positive pressure, thereby further ensuring the flexible plugging and unplugging of the offset stacking spring clip assembly 2.

[0040] In practice, the adapter terminal 3 is also connected to a cable, and the cable and the adapter terminal 3 are crimped or welded. In practice, other suitable cable connection methods can also be selected according to specific circumstances. The adapter terminal 3 can meet the wiring methods at different angles and can meet the requirements of new energy electric vehicles for compact space layout of different vehicles.

[0041] When in use, the current is introduced from the male terminal 1, which is plugged into the power input end of the offset stacking spring clip assembly 2. After the current flows through the offset stacking spring clip assembly 2, it flows out from the adapter terminal 3 plugged into the power output end of the offset stacking spring clip assembly 2 and the cable connected thereto. In a specific application, the number of single-piece spring forks 5 stacked in the offset stacking spring clip assembly 2 can be set according to the current flowing through. The more single-piece spring forks 5 are stacked, the greater the overcurrent capacity of the stacking spring clip assembly, and vice versa. Therefore, by adjusting the number of stacked single-piece spring forks 5, the overcurrent capacity of the stacking spring clip assembly is increased, and vice versa. The number of spring forks 5 can meet different current level conditions. At the same time, in the staggered stacked spring fork assembly of the present embodiment, a plurality of staggered elastic contact points (i.e., spring fork contacts 56) are provided at the power input end and the power output end of the staggered stacked spring sheet assembly 2 to form a plug interface that is respectively plugged with the male terminal 1 and the adapter terminal 3. Not only can flexible contact be achieved and the plug-in and pull-out force be reduced, but even under severe vibration conditions, resonance of the elastic contact points can be avoided to cause instantaneous disconnection caused by contact failure, thereby ensuring the stability and safety of the connection.

[0042] Embodiment 2

[0043] A staggered stacking spring fork assembly comprises a male terminal 1, a staggered stacking spring sheet assembly 2, a transfer terminal 3 and a spring sheet connector 4, such as Figure 4 As shown, the staggered superimposed spring sheet assembly 2 of this embodiment is composed of another form of single-piece spring fork 5, that is, the difference between the staggered superimposed spring fork assembly of this embodiment and the staggered superimposed spring fork assembly of the first embodiment is that the form of the single-piece spring fork 5 constituting the staggered superimposed spring sheet assembly 2 is different, specifically, the lengths of the four contact line ends are set differently, specifically, as Figure 5 As shown, the upper left spring fork 51 and the upper right spring fork 52 of the single-piece spring fork 5 of this embodiment are the same length, the lower right spring fork 53 and the lower left spring fork 54 are the same length, the upper left spring fork 51 and the lower left spring fork 54 are different in length, and the staggered superimposed spring sheet assembly 2 is composed of a plurality of single-piece spring forks 5 stacked in a positive and negative overlapping manner.

[0044] As another extended form, in practice, the lengths of the four contact line ends of the single-piece spring fork 5 can also be set so that the lengths of the upper left spring fork 51 and the upper right spring fork 52 are different, the lengths of the upper left spring fork 51 and the lower right spring fork 53 are the same, and the lengths of the upper right spring fork 52 and the lower left spring fork 54 are the same. It should be noted that there are many specific setting forms, which will not be described one by one here. In specific applications, corresponding changes can be made according to the central idea of ​​this solution.

[0045] like Figure 6 As shown, as another derivative form of the single-piece elastic fork 5, in practice, corresponding slots 58 can be set on the upper and lower sides of the single-piece elastic fork 5. In this case, the elastic connector 4 is a connecting plate, and specifically, a number of buckles that cooperate with the slots 58 can be set in parallel on the connecting plate, and a number of single-piece elastic forks 5 are clamped between the two connecting plates, that is, by plugging a number of single-piece elastic forks 5 into the connecting plates respectively, a number of single-piece elastic forks 5 are finally arranged in parallel, and the connecting plate and the single-piece elastic fork 5 are connected by the buckle slots 58, so that each single-piece elastic fork 5 cooperates with the connecting plate respectively, which can limit the rotation of the single-piece elastic fork 5 within a certain deflection range.

[0047] A staggered stacking spring fork assembly comprises a male terminal 1, a staggered stacking spring sheet assembly 2, a transfer terminal 3 and a spring sheet connector 4, such as Figure 7 As shown, the staggered superimposed spring sheet assembly 2 of this embodiment is composed of two other forms of single-piece spring forks stacked together, that is, the difference between the staggered superimposed spring fork assembly of this embodiment and the staggered superimposed spring fork assembly of the first embodiment lies in the different forms of the single-piece spring forks constituting the staggered superimposed spring sheet assembly 2. Specifically, the staggered superimposed spring sheet assembly 2 of this embodiment is composed of two single-piece spring forks stacked together at intervals. For the convenience of description and distinction, the two single-piece spring forks are named as the first single-piece spring fork 501 and the second single-piece spring fork 502 in this embodiment, wherein, as Fig. 9 As shown, the lengths of the upper left spring fork 51, the upper right spring fork 52, the lower right spring fork 53 and the lower left spring fork 54 of the second single-piece spring fork 502 are all the same. Figure 8 As shown, the upper left spring fork 51 and the lower left spring fork 54 of the first single-piece spring fork 501 have the same length, the upper right spring fork 52 and the lower right spring fork 53 have the same length, and the upper left spring fork 51 and the upper right spring fork 52 have different lengths, specifically, the upper right spring fork 52 is longer than the upper left spring fork 51. In practice, it can also be transformed into the upper left spring fork 51 and the upper right spring fork 52 have the same length, the lower right spring fork 53 and the lower left spring fork 54 have the same length, and the upper left spring fork 51 and the lower left spring fork 54 have different lengths. The offset superposition spring sheet assembly 2 of this embodiment is formed by the above two single-piece spring forks being superimposed on each other at intervals.

[0048] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
