Description

Technical Field

[0001] This utility model relates to the field of terminals, and in particular to an easy-to-plug connection terminal. Background Technology

[0002] With the development of technology and the progress of the times, people have higher requirements for the durability, reliability, compactness, space convenience, and cost control of industrial products. Currently, many electronic products, such as computers, mobile phones, and digital products, often require automotive terminal electrical connectors to connect different system units. To adapt to the specialized technological trends of today's computers, mobile phones, and digital products, the requirements for connection stability, reliability, convenience, and miniaturization of automotive terminal electrical connectors are becoming increasingly stringent.

[0003] Current automotive connectors feature terminals with a three-sided enclosed structure at the rear end, which makes the terminals unstable during soldering, prone to displacement, and resulting in poor soldering accuracy. Furthermore, during insertion with external terminals, excessive interference between the inner wall of the insertion cavity and the external terminals hinders insertion and removal. Therefore, it is necessary to improve the existing connector terminals. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide an easy-to-plug connection terminal, which can effectively solve the problems of existing connection terminals being unable to be stably placed during welding, resulting in poor welding accuracy, and excessive interference between the inner wall of the insertion cavity and the external terminal, which is not conducive to insertion and removal.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An easy-to-plug connector includes a body comprising a first side plate, a second side plate, a third side plate, and a fourth side plate integrally formed in sequence, the first side plate, the second side plate, the third side plate, and the fourth side plate forming a plug-in cavity; a first welding foot extending rearward from the rear end of the first side plate; a first elastic contact piece formed by stamping on the second side plate, the first elastic contact piece extending into the plug-in cavity; a second welding foot extending rearward from the rear end of the third side plate; and a second elastic contact piece formed by stamping on the fourth side plate, the second elastic contact piece extending into the plug-in cavity, an elastic clamping groove forming between the second elastic contact piece and the first elastic contact piece, the elastic clamping groove being directly opposite and communicating with the plug-in cavity.

[0007] As a preferred embodiment, the first side plate includes a first mating part and a second mating part, which are fixed together by the first mating part and the second mating part.

[0008] As a preferred embodiment, the first mating part is provided with a slot, and the second mating part is provided with a buckle, which engages with the slot to secure the mating part.

[0009] As a preferred embodiment, the slot is a dovetail groove and the buckle is a dovetail block. The design of the dovetail groove and the dovetail block makes the engagement of the first mating part and the second mating part more reliable. After the buckle is engaged, the first side plate will not open.

[0010] As a preferred embodiment, the second side plate has a first opening, and a first elastic contact extends rearward from the rear side of the first opening. The length of the first opening is one-eleventh of the length of the second side plate, and the length of the first elastic contact is half of the length of the second side plate. The first opening is designed with a small size, resulting in less insertion and extraction force with the external terminals. The first elastic contact is also designed with a larger size, resulting in a larger current-carrying area, which is more conducive to carrying large currents.

[0011] As a preferred embodiment, the fourth side plate has a second opening, and a second elastic contact extends rearward from the rear side of the second opening. The length of the second opening is one-eleventh of the length of the fourth side plate, and the length of the second elastic contact is one-half of the length of the fourth side plate. The second opening is designed with a small size, resulting in less insertion and extraction force with the external terminals. The second elastic contact is also larger, resulting in a larger current-carrying area, which is more conducive to carrying large currents.

[0012] As a preferred embodiment, a first limiting groove is provided on the rear side of the second side plate, and a second limiting groove is provided on the rear side of the fourth side plate. Both the first limiting groove and the second limiting groove cooperate with the external limiting structure to prevent the position of the terminal from shifting.

[0013] As a preferred embodiment, the front side of the third side plate is provided with an identification part, which is used for identification by automated equipment to prevent the welding direction from being reversed.

[0014] As a preferred embodiment, the elastic clamping groove is funnel-shaped, and the inner diameter of the elastic clamping groove decreases sequentially from front to back.

[0015] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0016] By forming a plug-in cavity by the first side plate, the second side plate, the third side plate and the fourth side plate, the plug-in cavity is designed to be surrounded on all four sides. During welding, the terminal can be placed stably, which effectively improves the welding accuracy. In addition, the second side plate is formed by stamping the first elastic contact piece. Both the first elastic contact piece and the second elastic contact piece extend into the plug-in cavity, which greatly reduces the interference force between the inner wall surface of the plug-in cavity and the external terminal, which is conducive to plugging and unplugging with the external terminal.

[0032] Please refer to Figures 1 to 3 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a body 100, which includes a first side plate 10, a second side plate 20, a third side plate 30 and a fourth side plate 40 integrally formed and connected in sequence, and the first side plate 10, the second side plate 20, the third side plate 30 and the fourth side plate 40 surround and form an insertion cavity 101.

[0033] The rear end of the first side plate 10 extends rearward to form a first welding foot 11. In this embodiment, the first side plate 10 includes a first mating part 12 and a second mating part 13. The first mating part 12 and the second mating part 13 are mated and fixed together. The first mating part 12 is provided with a slot 121, and the second mating part 13 is provided with a buckle 131. The buckle 131 is snapped and fixed together with the slot 121. Specifically, the slot 121 is a dovetail groove, and the buckle 131 is a dovetail block. The design of the dovetail groove and the dovetail block makes the mating of the first mating part 12 and the second mating part 13 more reliable. After the snapping is engaged, the first side plate 10 will not open.

[0034] The second side plate 20 is formed by stamping the first elastic contact piece 21, which extends into the insertion cavity 101. In this embodiment, the second side plate 20 has a first opening 22, and the first elastic contact piece 21 extends rearward from the rear side of the first opening 22. The length of the first opening 22 is one-eleventh of the length of the second side plate 20, and the length of the first elastic contact piece 21 is half of the length of the second side plate 20. The first opening 22 is designed with a small size, resulting in less insertion and extraction force with the external terminal. The first elastic contact piece 21 is also larger in size. After the external terminal is inserted into the insertion cavity 101, the first elastic contact piece 21 fits against the external terminal, resulting in a larger current-carrying area, which is more conducive to carrying large currents. In addition, a first limiting groove 23 is provided on the rear side of the second side plate 20.

[0035] The rear end of the third side plate 30 extends to form a second welding foot 31; in this embodiment, the front side of the third side plate 30 is provided with an identification part 32, which is used for identification by automated equipment to prevent the welding direction from being reversed.

[0036] The fourth side plate 40 is formed by stamping the second elastic contact piece 41. The second elastic contact piece 41 extends into the insertion cavity 101. An elastic clamping groove 102 is formed between the second elastic contact piece 41 and the first elastic contact piece 21. The elastic clamping groove 102 is directly connected to the insertion cavity 101. In this embodiment, the fourth side plate 40 has a second opening 42, and the second elastic contact 41 extends rearward from the rear side of the second opening 42. The length of the second opening 42 is one-eleventh of the length of the fourth side plate 40, and the length of the second elastic contact 41 is one-half of the length of the fourth side plate 40. The second opening 42 is designed with a small size, resulting in less insertion and extraction force with the external terminal. The second elastic contact 41 is larger in size, so that after the external terminal is inserted into the insertion cavity 101, the second elastic contact 41 fits against the external terminal, resulting in a larger current-passing area, which is more conducive to passing large currents. In addition, a second limiting groove 43 is provided on the rear side of the fourth side plate 40. The elastic clamping groove 102 is funnel-shaped, and the inner diameter of the elastic clamping groove 102 decreases from front to back.

[0037] The key design feature of this invention is that by forming a plug-in cavity around the first, second, third, and fourth side plates, the plug-in cavity is designed to be surrounded on all four sides, allowing the terminals to be placed stably during welding, effectively improving welding accuracy. Furthermore, the second side plate is stamped to form a first elastic contact piece, with both the first and second elastic contact pieces extending into the plug-in cavity, significantly reducing the interference force between the inner wall of the plug-in cavity and the external terminals, which is beneficial for plugging and unplugging with external terminals. In addition, the design of the two welding feet makes the welding more stable.

[0038] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
