Description

Technical Field

[0001] The utility model relates to the field of connectors, in particular to a stamping type energy storage connector. Background Art

[0002] Energy storage connectors are widely used in many fields, mainly including charging piles for electric vehicles (EV) and hybrid electric vehicles (HEV), solar power generation systems, grid energy storage systems, etc. In electric vehicles and hybrid electric vehicles, energy storage connectors play a key role. They are used to connect battery modules, form battery packs with multiple battery chips, and connect with motors, control units, and charging systems. Energy storage connectors have high current transmission capacity and reliability, ensuring efficient operation and fast charging of electric vehicles. In addition, energy storage connectors also have important applications in solar power generation systems. They are used to connect solar panels and energy storage devices to convert solar energy into electrical energy and store it. In grid energy storage systems, energy storage connectors can be used to connect battery components and inverters, as well as to connect energy storage systems with the main grid. They play an important role in improving the efficiency and stability of power systems. In short, energy storage connectors are widely used in many fields and are of great significance for improving energy utilization efficiency, reducing energy consumption, and promoting sustainable development.

[0003] The terminal structure of the energy storage connector usually includes a plug terminal 1 and a socket terminal 2. Figure 1 and Figure 2 As shown, the plug terminal 1 includes a pin end 101 and a terminal 102. The pin end 101 of the prior art needs to be provided with a limiting outer ring for mating and inserting into the socket, so the pin end 101 is generally completed by lathing. The disadvantage of lathing the plug terminal 1 is low processing capacity and high material cost. Figure 3 As shown, the socket terminal 2 includes a crimping end 201 and a connecting end 202. After the crimping end 201 passes through the punched mounting hole, the insert 203 is riveted along the mounting hole. The insert 203 is connected to the mounting hole by riveting. The riveting connection between the two parts will increase the resistance and there is a risk of falling off. In addition, the insert 203 is made by turning, and the inside of the insert 203 is a socket. The socket needs to be installed with a spring. After the pin end 101 is inserted along the socket, the spring contacts the pin end 101 to achieve electrical connection. The socket terminal 2 has many components as a whole, which not only affects the stability of the connection, but also has a long production cycle and high cost. Utility Model Content

The anti-touch finger is designed as a detachable structure, which requires a slot to be punched, and the anti-touch finger is installed inside the elastic end after the injection molding is completed. The anti-touch finger can prevent the elastic contact piece from closing after being pressed, which affects the conductive performance.

[0011] Furthermore, a limiting plug is provided at one end of the anti-touch finger away from the external threaded joint, the diameter of the limiting plug is larger than the diameter of the elastic end, and the limiting plug is limited to the end of the elastic end away from the waterproof plastic part.

[0012] Furthermore, there are six slots in total, and the six slots evenly separate the elastic ends to form six elastic contact pieces.

[0013] Furthermore, the angle formed by the center extension line of the wire pressing end and the connecting end is a right angle.

[0014] Furthermore, the connection end is punched by a punching needle to form an expanded hole.

[0015] Furthermore, the plug terminal and the socket terminal are both made of copper.

[0016] The beneficial effects produced by the utility model are as follows: both the plug terminal and the socket terminal are produced by a stamping process, with high production efficiency and low production cost; the elastic end of the plug terminal forms an elastic contact piece through a stamping slot; after the elastic end is inserted into the jack, the elastic contact piece will be pressed against the inner wall of the jack under the action of its own elastic force, so the connection is more stable and not easy to loosen after the connection; the jack of the socket terminal is an integrated structure directly completed by stamping, and the risk of falling off can be eliminated after the jack and the elastic contact piece are connected; in addition, the waterproof plastic part formed in the middle of the plug terminal is also connected to an anti-touch finger inside, which can play a role in auxiliary support of the elastic contact piece, so as to avoid the elastic contact piece from closing after being pressed to affect the conductive performance, and ensure that the elastic contact piece is firmly pressed against the inner wall of the jack, thereby forming current conduction.

DETAILED DESCRIPTION

[0031] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] In this embodiment, refer to Figure 4-Figure 12 A stamped energy storage connector specifically implemented includes a plug terminal 1 and a socket terminal 2 for mating and electrical connection. The plug terminal 1 and the socket terminal 2 are both composed of a hollow metal tube, specifically copper.

[0033] Figure 4-Figure 7As shown, the plug terminal 1 includes an elastic end and a wiring terminal 101, the wiring terminal 101 is formed into a flat structure by stamping, and a punching hole 102 for connecting a wire is provided on the wiring terminal 101. Six slots 103 are formed on the elastic end by stamping, and the six slots 103 separate the elastic end into six elastic contact pieces 104 with equal spacing. A waterproof plastic part 105 for waterproofing is formed between the elastic end and the wiring terminal 101, and the waterproof plastic part 105 is wrapped around the inner and outer surfaces between the elastic end and the wiring terminal 101. An internal threaded hole 107 that is conductive to the inside of the elastic end is provided in the middle of the waterproof plastic part 105, and the opening of the internal threaded hole 107 is in the same direction as the opening of the elastic end. An anti-touch finger 106 for auxiliary support of the elastic contact piece 104 is provided inside the elastic end, and an external threaded joint 108 for matching and screwing into the internal threaded hole 107 is provided at one end of the anti-touch finger 106 close to the internal threaded hole 107. The anti-touch finger 106 is designed as a detachable structure. During the production process, the slot 103 needs to be punched first, and the anti-touch finger 106 needs to be injection molded independently. After the injection molding is completed, the anti-touch finger 106 is installed into the inside of the elastic end. The anti-touch finger 106 can prevent the elastic contact piece 104 from closing after being pressed and affecting the conductive performance.

[0034] like Figure 8 and Fig. 9 As shown, the socket terminal 2 includes a wire pressing end 201 and a connecting end 202. A flat bending structure is formed between the wire pressing end 201 and the connecting end 202 by stamping, so that the wire pressing end 201 and the central extension line of the connecting end 202 form an angle. In this embodiment, the angle formed by the central extension line of the wire pressing end 201 and the connecting end 202 is a right angle, which can realize the turning power connection and has stronger applicability. The connecting end 202 of this embodiment is formed by punching a punch needle to form an expanded hole. The connecting end 202 can be connected to other electrical connectors according to the design requirements of the product. The inside of the wire pressing end 201 is reserved with a socket 203 for mating and inserting the elastic end. After the elastic end is inserted into the socket 203, the elastic contact piece 104 will be pressed against the inner wall of the socket 203 under the action of its own elastic force.

[0035] In addition, a stopper plug 109 is provided at one end of the anti-touch finger 106 away from the external threaded connector 108. The stopper plug 109 and the anti-touch finger 106 are an integrally formed structure. The diameter of the stopper plug 109 is larger than the diameter of the elastic end. Figure 6 and Fig.12 As shown, the limiting plug 109 is limited to the end of the elastic end away from the waterproof plastic part 105 . After the elastic end is inserted into the insertion hole 203 , the outer end of the limiting plug 109 abuts against the bottom surface of the insertion hole 203 .

[0036] The plug terminal 1 and the socket terminal 2 of this embodiment are both produced by a stamping process using a hollow metal tube. The stamping process has high production efficiency and low production cost. The elastic end of the plug terminal 1 forms an elastic contact piece 104 through a stamping slot 103. After the elastic end is inserted into the plug hole 203, the elastic contact piece 104 will be pressed against the inner wall of the plug hole 203 under the action of its own elastic force, making the connection more stable and not easy to loosen after connection. Fig.12 As shown, the socket 203 of the socket terminal 2 is an integrated structure that is directly completed by stamping. After the socket 203 is connected to the elastic contact piece 104, the risk of falling off can be eliminated. In addition, the waterproof plastic part 105 formed in the middle of the plug terminal 1 is also connected to the inside with an anti-touch finger 106. The anti-touch finger 106 can play a role in auxiliary support of the elastic contact piece 104, avoiding the elastic contact piece 104 from closing after being pressed and affecting the conductive performance, ensuring that the elastic contact piece 104 is firmly attached to the inner wall of the socket 203, thereby forming current conduction.
