Description

TECHNICAL FIELD

[0001] The utility model relates to the terminal structure of elastic clamping wire, especially a kind of terminal structure with simple structure, material saving and can effectively reduce overall volume and produce stable movable clamping wire. BACKGROUND

[0002] As Figures 1-2 As shown, it is a kind of traditional terminal device with the function of elastic clamping wire, which is mainly composed of multiple terminal units C connected with each other and a side cover;Wherein the terminal unit C includes: terminal assembly 3 and terminal seat 4, the terminal assembly 3 is composed of a terminal 31 and a metal spring 32, the terminal 31 middle section is provided with a vertical stop portion 311, the stop portion 311 one end is connected with a vertical bending foot portion 313 through a connecting bending portion 312, the stop portion 311 other end both sides are connected with a positioning portion 315 extending bending towards foot portion 313 through a bending side limiting portion 314, so that the space 317 can be formed between the two side limiting portions 314, and the positioning portion 315 is provided with a convex point 316 on one side of the receiving space 317.

[0003] The metal spring 32 is arranged in the receiving space 317, the metal spring 32 middle section is provided with a bending portion 321, the metal spring 32 one end forms a positioned end 322, the positioned end 322 is provided with a hook portion 324, which can be hooked on the convex point 316 and combined on the positioning portion 315, the metal spring 32 other end extends towards the stop portion 311 to form a carding end 323 with elastic activity, so that the carding end 323 can cooperate with the inner edge of the stop portion 311 to form a structure capable of clamping wire.

[0004] The terminal seat 4 is provided with a containing space 41 capable of containing the terminal assembly 3, the containing space 41 is at least communicated with outside through a channel 42 and a wire insertion hole 43, an operation hole 44;Wherein the channel 42 is used for the foot portion 313 of the terminal 31 to protrude outward, and the wire insertion hole 43 is corresponding to the outer edge of the carding end 323 of the metal spring 32, so that the wire is inserted between the carding end 323 and the stop portion 311 to form clamping and positioning, and the operation hole 44 is used for tool to enter to release the clamping of the carding end 323 to the wire.

[0005] However, the above structure has the following disadvantages in actual application:

[0006] A. Since the terminal 31 comprises the abutted positioning portion 315, the side limiting portion 314, the stop portion 311, the connecting bent portion 312 and the pin portion 313, the structure is complicated and the length is long, which consumes more material. Meanwhile, the accommodation space 317 (hollow portion) between the two side limiting portions 314 produces a large area of waste, which makes the overall material and manufacturing cost difficult to reduce.

[0007] B. Since the overall volume of the terminal 31 after forming is large, the terminal seat 4 accommodating the terminal 31 also needs to maintain a large volume, which is not conducive to the development of product miniaturization.

[0008] C. Since the two side limiting portions 314 can only cross the two sides of the clamping end 323 of the metal spring 32 to form point contact, the clamping end 323 cannot be stably guided and laterally limited in a large section, which is easy to cause the metal spring 32 to deviate and skew during movement. Therefore, the metal spring 32 must use the surrounding portion of the accommodation space 41 of the terminal seat 4 (plastic material) to limit the movement of the metal spring 32, which is easy to cause wear and damage.

[0009] D. Since the shape structure of the stop portion 311 in the terminal 31 limits the pin portion 313 to be arranged on the side away from the stop portion 311, and each terminal seat 4 is arranged with the channel 42 on a single side of the accommodation space 41 for the stop portion 311 to pass through and protrude outward, in order to meet the insulation requirement between the pin portions 313, a sufficient distance must be maintained between the pin portions 313, which makes it difficult for each terminal unit C to meet the trend of small and exquisite products.

[0010] In view of the above-mentioned shortcomings of the conventional terminal device in actual application, the inventor has researched and improved the device, and finally the present utility model is produced. Utility model content

[0122] In this embodiment, the base 110 is respectively provided with two opposite first ends 1111, second ends 1112 and two opposite first sides 1113, second sides 1114 on the outer circumferential side of the receiving portion 111, the pin portion is arranged close to the outer side of the first end 1111 and forms a first pin 114, and a first positioning end 116 with a larger width is arranged between the first pin 114 and the first end 1111.

[0123] The metal elastic sheet 12 has a bending part 121 in the middle section, and a positioning part 122 at one end, which is combined with the positioning part 112 to form a positioning, and the other end of the metal elastic sheet 12 is obliquely inserted into the accommodating part 111 to form a clamping end 123, which is away from the positioning part 112, and the accommodating part 111 has limiting parts 113 at the edges other than the positioning part 112, which extend along the extending direction of the clamping end 123, and the limiting parts 113 are formed by the edges of the accommodating part 111 and the base 110, so that the clamping end 123 can be elastically clamped with the inner edge of the accommodating part 111 (away from the positioning part 112) and the limiting parts 113.

[0124] The terminal seat 2 has a receiving space 21 on one side surface, which receives the first terminal assembly 1, and the receiving space 21 has a positioning column 213 inside, which is stopped in the bending part 121 of the metal elastic sheet 12 to form a positioning, and the receiving space 21 has a first channel 211, a second channel 212, a wire insertion hole 22, and an operation hole 23, which are connected to the outside; the first channel 211 and the second channel 212 correspond to the outer ends of the first end part 1111 and the second end part 1112 of the accommodating part 111, so that the first pin 114 can extend to the outside of the terminal seat 2 through the first channel 211, the wire insertion hole 22 extends between the outer edge of the clamping end 123 of the metal elastic sheet 12 and the inside of the accommodating part 111, and the operation hole 23 extends between the clamping end 123 and the bending part 121.

[0127] Compared with the terminal 31 of the conventional terminal assembly 3, the first terminal 11 only has the main structures such as the accommodating portion 111 and the first pin 114 (pin portion), so that the overall height is greatly reduced and the structure is simpler, and the material and production cost can be saved; meanwhile, the limiting portion 113 formed at the edge of the accommodating portion 111 can effectively reduce the waste generated in the production process, so as to improve the overall economic benefit; in addition, the limiting portion 113 and the clamping end 123 are respectively formed in line contact, which can not only stably guide and laterally limit the movement of the clamping end 123 in a large section, so as to effectively avoid the deviation and skew of the metal spring 12 during the movement, but also can reduce the abnormal contact between the surrounding of the accommodating space 21 and the metal spring 12, so as to cause the abnormal wear and damage of the terminal seat 2.

[0128] As shown in Figure 7 As shown in

[0129] As shown in Figures 8-9 As shown in

[0130] In the embodiment, the pin portion is arranged close to the outer side of the second end portion 1112 and forms a second pin 115a; and a second positioning end portion 117a with a larger width is arranged between the second pin 115a and the second end portion 1112.
