[0043] Please see Figures 1 to 5 This embodiment provides a crimping device for a terminal block. This crimping device is used to produce spring-loaded switch terminals 60, that is, to accurately and efficiently press the contact spring 5 into the housing 6.

[0044] like Figure 1 As shown, in this embodiment, the crimping device for the terminal block includes: a display 4, a base 1, and a crimping device 3.

[0045] The upper surface of the base 1 is a flat tabletop. The base 1 can be rectangular or other shapes, and can be made of hard metals such as stainless steel or aluminum alloy. The upper surface of the base 1 serves as the space for terminal block production. The base 1 has a certain height, specifically between 0.8 meters and 1.2 meters. To fully utilize the internal space of the base 1, a storage space is provided inside, and a cabinet door connecting to the storage space is opened on the side of the base 1. To facilitate the movement of the terminal block clamping device, casters can be provided at the four corners of the bottom of the base 1.

[0046] The display 4 is mounted on the base 1 via an L-shaped mounting rod. The display 4 is used to display the control or operating parameters of the terminal pressure head device, and multiple control buttons may also be provided on the display 4, including a power button, a pause button, a setting button, etc.

[0047] The pressing device 3 is disposed on the upper surface of the base 1. The pressing device 3 is used to press the contact spring 5 into the housing 6 of the terminal block. The pressing device 3 includes a feed groove 31, a vertical pressing head 35 and a feeding slider 331.

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, the feed trough 31 is used to transmit the housing 6 of the terminal block, and a first push cylinder 32 is provided at the end. The first push cylinder 32 is perpendicular to the feed trough 31 and is used to send the housing 6 below the vertical pressing head 35.

[0049] The feeding slider 331 is provided with a picking push rod 34, which is used to press the head of the contact spring 5 to remove the contact spring 5; and the feeding slider 331 is connected to a second pushing cylinder 33, which is arranged parallel to the first pushing cylinder 32 and is used to feed the feeding slider 331 into the lower part of the vertical pressing head 35.

[0050] The vertical pressing head 35 includes a horizontal push rod 352, a vertical cylinder 353, and an inverted U-shaped gripper 351 located at the bottom. The width of the two sides of the gripper 351 is equal to the width of the contact spring 5. The vertical pressing head 35 is used to grip the contact spring 5 from the feeding slider 331 and press it into the insertion hole of the housing 6.

[0051] In this embodiment, the width of the feed groove 31 is slightly larger than the length of the housing 6 of the spring-loaded switch terminal 60. The housing 6 is arranged side by side with the feed groove 31 and can slide along the feed groove 31. The housing 6 at the very end of the feed groove 31 can be sent to the bottom of the vertical pressing head 35 by the first push cylinder 32, ready to be inserted into the contact spring 5. In order to facilitate the movement of the housing 6 pushed to the bottom of the vertical pressing head 35, a discharge groove 37 is provided below the vertical pressing head 35. The shape of the discharge groove 37 is the same as that of the feed groove 31. The discharge groove 37 is parallel to the feed groove 31 and located below the vertical pressing head 35; the first push cylinder 32 pushes the housing 6 to the first end of the discharge groove 37; the second end of the discharge groove is provided with a receiving inlet 36 for receiving the terminal block that has been pressed into the contact spring 5, and a container is provided below the receiving inlet 36 to receive the terminal block.

[0052] like Figure 2 and Figure 3 As shown, the contact springs 5 ​​to be assembled are arranged side by side next to the feeding slider 331, with a small portion of each adjacent contact spring 5 adhering together (i.e., a small portion of metal in the middle of the contact spring 5 is not completely broken). Each contact spring 5 has a certain curvature. When the picking push rod 34 presses against the end of the contact spring 5, the contact spring 5 is rotated by a certain angle, thus separating from the adjacent contact spring. It is then pushed by the feeding slider 331 to below the vertical pressing head 35. The picking push rod 34 has a small volume and travel distance, therefore a small cylinder or electromagnetic push rod can be used.

[0053] like Figure 3 and Figure 5 As shown, in this embodiment, a U-shaped bracket is provided at one end of the tablet feeding slider 331 near the vertical tablet pressing head 35. The tablet picking push rod 34 is fixed to the U-shaped bracket, and the movable end of the tablet picking push rod 34 extends through the U-shaped bracket towards the contact spring 5. In other embodiments, the tablet picking push rod 34 can also be fixed to the end of the tablet feeding slider 331 using other commonly used fixing brackets.

[0054] As the name suggests, the vertical pressing head 35 can be driven by the vertical cylinder 353 to press down vertically, and is used to press the contact spring 5 into the insertion hole inside the housing 6. The vertical pressing head 35 can also be driven by the horizontal push rod 352 to move horizontally. After the vertical pressing head 35 presses the contact spring 5 into the insertion hole inside the housing 6, the horizontal push rod 352 can control the vertical pressing head 35 to move horizontally backward by the distance of one housing 6, thereby moving the currently assembled housing 6 forward along the feeding groove so that the feeding groove can receive newly fed housing 6. The horizontal push rod 352 can also be a small cylinder.

[0055] like Figure 3 and Figure 5 As shown, the working process of the crimping device of this terminal block is as follows: the first push cylinder 32 pushes the housing 6 at the end of the feed groove 31 into the discharge groove 37 below the vertical pressing head 35. The second push cylinder 33 controls the feeding slider 331 to move to the initial position (i.e., the position of the spring strip). The picking push rod 34 extends to pick up a contact spring 5 from the spring strip. Then, the second push cylinder 33 pushes the feeding slider 331 and the contact spring 5 on it to the lower part of the vertical pressing head 35. Finally, the vertical pressing head 35 picks up the contact spring 5 on the feeding slider 331 and inserts it into the insertion hole of the housing 6. Finally, the horizontal push rod 352 pushes the housing 6 with the inserted contact spring 5 along the discharge groove 37 to a position. The assembled terminal block exits from the second end of the discharge groove 37 (i.e., the lower part of the feed groove 35). Figure 3 Enter the receiving inlet 36 (top left of center). Repeat the above steps to achieve continuous operation.

[0056] like Figure 4 The diagram shows the structure of the spring-loaded switch terminal 60 produced by the terminal press device in this embodiment after being connected to the wire 61. One end of the contact spring 5 of the spring-loaded switch terminal 60 is provided with a second contact 51, and the other end of the contact spring 5 extends towards the bottom of the housing 6 for connecting the wire 61. There is no first contact 52 on the housing 6 opposite to the second contact 51. When the first contact 52 and the second contact 51 abut against each other, the spring-loaded switch terminal 60 is connected; otherwise, it is disconnected.

[0057] The pressing device of the terminal block in this embodiment can automatically complete the feeding of the housing 6, the picking of the contact spring 5 and the accurate pressing into the housing 6, thus greatly improving the production efficiency and product quality of the spring-type switch terminal 60.

[0058] like Figure 5 As shown, in this embodiment, the outer sides of the ends of the gripping arms on both sides of the gripper 351 taper inwards towards the center, and the thickness of the ends of the gripping arms is less than the thickness of the top. In this embodiment, the outer sides of the gripping arms of the gripper 351 are thinned, thus allowing them to better extend into the housing 6 and reducing interference with other surrounding structures, thereby improving operational stability.

[0059] like Figure 1 and Figure 2As shown, in this embodiment, the terminal pressure head device further includes a liquid injection device 2, which includes a liquid injection gun 23 for injecting lubricating fluid into the socket. The liquid injection gun 23 is movably mounted on a transverse track 22, which is movably mounted on a longitudinal track 21, which is mounted on the base 1. Drive motors are respectively mounted on the transverse track 22 and the longitudinal track 21 to drive the liquid injection gun 23 to move laterally along the transverse track 22 and to drive the transverse track to move longitudinally along the longitudinal track 21. The liquid injection gun 23 is mounted on a lifting bracket and a lifting slider. The lifting bracket is mounted on the transverse track 22, and the lifting slider is vertically slidable on the lifting bracket and is driven by a drive motor for lifting. The injection gun 23 can be moved above the housing 6 to be assembled (i.e., above the feeding groove) via the transverse rail 22 and the longitudinal rail 21. Before inserting the contact spring 5, lubricant is injected into the insertion hole of the housing 6, thereby improving the lubrication of the insertion hole and reducing the insertion resistance of the contact spring 5. The lifting, lateral, and longitudinal movement drive structures of the injection gun 23 all adopt conventional slide rail and drive motor drive structures in the art, and will not be described in detail here.

[0060] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
