Description

Crimp connector and method of manufacturing the same

Technical Field

The present invention relates to a crimp connector, and more particularly, to a crimp connector and a method for manufacturing the same.

Background

Referring to the patent of invention No. CN105098432A published in china, a press-fit connector is disclosed, in which a first spring portion is connected between an upper flat plate portion and a lower flat plate portion, and a second spring portion extending from the lower flat plate portion and located below the upper flat plate portion to support the upper flat plate portion. However, when the upper flat plate part is pressed downwards, the first spring part connected to the side edge of the upper flat plate part firstly bears all the pressure, and after the upper flat plate part presses downwards against the top end of the second spring part, the first spring part and the second spring part bear the pressure together. In this process, the first spring part tends to be subjected to more pressure than the second spring part, so that the first spring part is more vulnerable. Furthermore, the positions of the first spring part and the second spring part which bear the pressure are asymmetric relative to the upper flat plate part, so that the pressures borne by the two spring parts are unbalanced, and the up-and-down movement of the upper flat plate part is not stable enough. Furthermore, the widths of the first spring part and the second spring part in the transverse direction are both larger than the thicknesses of the first spring part and the second spring part in the vertical direction, namely, the first spring part and the second spring part are both vertically arranged structures, and a supporting component for preventing the upper flat plate part from continuously moving downwards is not arranged, so that the stress of the spring parts at the position of the root base part is large, the yield loss state is easy to occur, and the stability of the rebound height is influenced. Furthermore, since the two spring portions are formed by winding the upper flat plate portion in the same direction, the winding process is complicated, and the two elastic portions are easily interfered with each other, which makes the manufacturing difficult.

Therefore, there is a need to provide a new crimp connector to overcome the above-mentioned drawbacks.

The connecting portion 46a of the second elastic arm 45A of the first elastic portion 41 is connected to the left end side edge of the first base plate 21 at a position near the front end. Referring to fig. 1 to 9, the first beam portion 46b of the second elastic arm 45A of the first elastic portion 41 horizontally extends rearward from the rear end edge of the upper end of the connecting portion 46 a. The second beam portion 46c of the second elastic arm 45A of the first elastic portion 41 is bent rightward in the transverse direction from the rear end edge of the first beam portion 46b and extends horizontally. The distance between the front end of the sloping plate part 44b of the first elastic arm 43A of the first elastic part 41 and the upper surface of the first bottom plate 21 in the vertical direction is greater than the distance between the rear end of the sloping plate part 44b and the upper surface of the first bottom plate 21 in the vertical direction, that is, the sloping plate part 44b of the first elastic arm 43A of the first elastic part 41 extends obliquely upward from back to front. The second bent portion 44c of the first elastic arm 43A of the first elastic portion 41 is bent forward from the lower end edge of the second beam portion 46c to connect the lower end of the inclined plate portion 44 b. The first bent portion 44a of the first elastic arm 43A of the first elastic portion 41 is bent rearward from the upper end of the inclined plate portion 44b to connect the left side of the front end side edge of the pressing plate 3.

Referring to fig. 7, the second elastic portion 42 is entirely located on the right side of the contact point 31 of the platen 3 when viewed in the vertical direction. The connecting portion 46d of the second elastic arm 45B of the second elastic portion 42 is connected to the right end side edge of the second base plate 22 at a position close to the rear end. Referring to fig. 1 to 9, the first beam portion 46e of the second elastic arm 45B of the second elastic portion 42 horizontally extends forward from the front edge of the upper end of the connecting portion 46 d. The second beam portion 46f of the second elastic arm 45B of the second elastic portion 42 is bent laterally leftward from the front end edge of the first beam portion 46e and extends horizontally. The distance between the rear end of the sloping plate portion 44e of the first elastic arm 43B of the second elastic portion 42 and the upper surface of the second bottom plate 22 in the vertical direction is greater than the distance between the front end of the sloping plate portion 44e and the upper surface of the second bottom plate 22 in the vertical direction, that is, the sloping plate portion 44e of the first elastic arm 43B of the second elastic portion 42 extends obliquely upward from front to back. The second bent portion 44f of the first elastic arm 43B of the second elastic portion 42 is bent rearward from the lower end edge of the second beam portion 46f to connect the lower end of the ramp portion 44 e.

elastic arms

43A, 43B are surrounded by the two second

elastic arms

45A, 45B when viewed in the up-down direction.

As can be seen from the above description, the first elastic part 41 and the second elastic part 42 of the crimp connector 100 of the present invention have the same structure, but the first elastic part 41 and the second elastic part 42 are located below the pressing plate 3 and spaced apart in the transverse direction, and are oppositely displaced from each other with the pressing plate 3 as the center and are relatively independent, and do not overlap each other in the vertical direction. Therefore, when the rear view of the compression connector 100 of the present invention viewed from the rear to the front is the same as the front view shown in fig. 5, and the right view viewed from the right to the left is the same as the left view shown in fig. 6. The first elastic part 41 and the second elastic part 42 do not interfere with each other in the downward compression process, and the structure is simple.

When the pressing plate 3 is pressed from top to bottom, the pressing plate 3 moves downward and receives a supporting force from the first elastic part 41 and the second elastic part 42 from bottom to top. As the pressing plate 3 moves downward, the two first

elastic arms

43A, 43B and the two second

elastic arms

45A, 45B of the first elastic part 41 and the second elastic part 42 are compressed downward, and the two second

elastic arms

45A, 45B may be inclined inward. In the downward movement degree of the pressing plate 3, the two second

bent portions

44c, 44f of the first elastic portion 41 and the second elastic portion 42 first press against the upper surfaces of the first bottom plate 21 and the second bottom plate 22, so that the two second

elastic arms

45A, 45B of the first elastic portion 41 and the second elastic portion 42 do not continue to be compressed downward and do not further incline inward, and when the pressing plate 3 continues to move downward, the two first

elastic arms

43A, 43B of the first elastic portion 41 and the second elastic portion 42 continue to be compressed downward, so that the stress borne by the two second

elastic arms

45A, 45B is reduced, the lowering amount of the two second

elastic arms

45A, 45B is reduced, and the elastic capacity of the two second

elastic arms

45A, 45B is ensured. When the pressing plate 3 continues to move downward and compresses the two first

elastic arms

43A, 43B downward to approach the preset limit of the present invention, the lower ends of the two ears 32 are pressed downward against the upper surfaces of the first bottom plate 21 and the second bottom plate 22, so that the two first

elastic arms

43A, 43B are no longer compressed downward, thereby reducing the amount of the two first

elastic arms

43A, 43B being taken down, and also protecting the whole press-fit connector 100 from being compressed downward, thereby protecting the elastic capabilities of the two first

elastic arms

43A, 43B and the whole press-fit connector 100, and effectively ensuring that the pressing plate 3 can recover to the preset height position when no longer being pressed downward. It can be seen that the different arrangement directions of the first

elastic arms

43A, 43B and the second

elastic arms

45A, 45B of the elastic portion of the crimp connector 100 according to the present invention can achieve the beneficial effect of protecting the stability of the entire crimp connector 100.

The present invention further provides a method of manufacturing a crimp connector 100: comprises the following steps of (a) carrying out,

in a first step, a metal plate (not shown) is provided, the metal plate (not shown) is punched to form a pressing plate 3 having a contact point 31, a first elastic portion 41 and a second elastic portion 42 respectively connected to opposite side edges of the pressing plate 3, and a strip (not shown) in which the first bottom plate 21 is connected to the first elastic portion 41 and the second bottom plate 22 is connected to the second elastic portion 42.

Referring to fig. 10, in the second step, the

second beam portions

46c and 46f of the two second

elastic arms

45A and 45B of the first elastic portion 41 and the second elastic portion 42 are bent downward, respectively.

Referring to fig. 10, in the third step, the second bent portion 44c of the first elastic arm 43A of the first elastic portion 41 is bent backward, and the second bent portion 44f of the first elastic arm 43B of the second elastic portion 42 is bent forward.

Referring to fig. 12, in the fourth step, the first bent portion 44a of the first elastic arm 43A of the first elastic portion 41 is bent backward, and the first bent portion 44d of the first elastic arm 43B of the second elastic portion 42 is bent forward.

Referring to fig. 12, in the fifth step, the connecting portion 46a of the second elastic arm 45A of the first elastic portion 41 is bent horizontally to the right. The connecting portion 46d of the second elastic arm 45B of the second elastic portion 42 is horizontally bent leftward. The first floor 21 and the second floor 22 are made horizontally coplanar as shown in fig. 1.

While the above description is a preferred embodiment of the method for manufacturing the crimp connector 100 according to the present invention, in other embodiments, the first elastic portion 41 and the second elastic portion 42 may be formed by bending separately.

In the first embodiment of the press-fit connector 100 of the present invention, the lug portions 32 are connected to the other two side edges of the two side edges to which the two elastic portions are connected, respectively. Since the two ear portions 32 have a long up-down length, it is preferable that before the second step, the two ear portions 32 are bent downward respectively so that the two ear portions 32 are perpendicular to the press plate 3. In the second embodiment, when the length of the ear portion 32 'in the up-down direction is small, the two ear portions 32' may be finally bent after the fifth step. Eventually, the two ear portions 32, 32' are located in the gaps 47 between the

respective ramp portions

44b, 44e and the

first beam portions

46b, 46 e.

Compared with the prior art, the invention has the following beneficial effects: the two elastic parts are respectively connected to the two opposite side edges of the pressing plate 3 and are arranged in a staggered manner, so that the structural strength is better, the pressure applied to the pressing plate 3 can be uniformly distributed to the two elastic parts, and the two elastic parts can provide balanced elastic support for the pressing plate 3, so that the stable downward movement of the pressing plate 3 is ensured, and the longer service life of the two elastic parts is also ensured; during manufacturing, the bending step of the elastic part is simple, and the manufacturing is easy.
