Description

Technical Field

[0001] This utility model relates to the field of communication equipment, and more specifically to a pressing device for IDC assembly. Background Technology

[0002] IDC (Insulation Displacement Connector) is a type of connector that features piercing terminals. These terminals pierce the enameled wire sheath to establish a connection between the terminal and the conductor, or they can be directly plugged into a PCB to connect the terminal to the PCB. IDC connectors are widely used in various electronic products, such as in communication equipment, where they are commonly used in network communication interfaces. Because network communication interfaces use different protocols, different connectors need to be developed for different protocols or specific devices. These different connectors have different structures, such as different PCB traces, resulting in different terminal positions. In the laboratory development and design of connectors, several components need to be assembled into a whole to verify whether the connector's function and performance meet the design requirements. During assembly, the terminals need to be inserted into the corresponding positions on the PCB. Traditionally, this is done manually using tools such as pliers to insert the terminals one by one into the designated positions on the PCB. However, this insertion process requires considerable force, and manual operation can easily lead to misalignment, deviation, deformation, damage to the surface plating, or even damage to the PCB. There are already devices on the market that can perform automatic pin insertion. Although existing pin insertion devices may be modified to adapt to the insertion of the terminals of the aforementioned connectors, the number of test samples assembled during the laboratory development and design process is not large and does not involve large-scale product assembly, so the cost of using automatic pin insertion devices is too high. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a pressing device for IDC assembly.

[0004] This utility model is achieved using the following solution:

[0005] A pressing device for IDC assembly includes a base, a guide post vertically mounted on the base, a pressing mechanism and a pressing guide mechanism connected to the guide post, a positioning fixture mounted on the base, and a pressing drive mechanism mounted on the base for driving the pressing mechanism to press down. The pressing mechanism is located above the pressing guide mechanism. The pressing guide mechanism includes a first connecting seat connected to the guide post, a guide seat connected to the first connecting seat, and an auxiliary positioning block connected to the guide seat. The auxiliary positioning block has a plurality of positioning guide holes for placing terminals and is located above the positioning fixture. The pressing mechanism has a pressing member located above the auxiliary positioning block.

[0006] Furthermore, the pressing mechanism also includes a second connecting seat connected to the guide post and a lower pressing seat connected to the second connecting seat, wherein the lower pressing member is connected to the lower pressing seat.

Detailed Implementation

[0023] To facilitate understanding of this utility model by those skilled in the art, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0024] Reference Figures 1 to 5This utility model provides a pressing device for IDC assembly, including a base 1, a guide post 11 vertically arranged on the base 1, a pressing mechanism 2 and a pressing guide mechanism 3 connected to the guide post 11, a positioning fixture 4 arranged on the base 1, and a pressing drive mechanism 5 arranged on the base 1 for driving the pressing mechanism 2 downward. The pressing mechanism 2 is located above the pressing guide mechanism 3. The pressing mechanism 2 and the pressing guide mechanism 3 can move vertically along the guide post 11. The positioning fixture 4 is used to place the PCB, and the pressing drive mechanism 5 is used to drive the pressing mechanism 2 downward to press the terminals into the PCB on the positioning fixture 4. In this embodiment, at least two guide posts 11 are provided to ensure that the pressing mechanism 2 and the pressing guide mechanism 3 do not shift during movement.

[0025] The pressing and guiding mechanism 3 includes a first connecting seat 31 connected to the guide post 11, a guide seat 32 connected to the first connecting seat 31, and an auxiliary positioning block 33 connected to the guide seat 32. The auxiliary positioning block 33 is provided with a plurality of positioning guide holes 34 for placing terminals. The auxiliary positioning block 33 is located above the positioning fixture 4. The pressing mechanism 2 has a lower pressing member 21, which is located above the auxiliary positioning block 33. The positioning guide holes 34 on the auxiliary positioning block 33 can be set according to the position of the terminals of the product to be processed. When performing terminal insertion operations for products of different specifications, the corresponding auxiliary positioning block 33 can be replaced. When inserting terminals, the terminals can be first inserted into the preset positioning guide holes 34. Then, the pressing mechanism 5 drives the pressing mechanism 2's pressing member 21 to move downward. After the pressing member 21 contacts the top of the terminal, it continues to move downward until the terminal is inserted into the preset hole of the PCB. During the downward movement of the pressing member 21, the top of all terminals contacts the bottom surface of the pressing member 21. Therefore, one pressing can press all terminals into the PCB at the same time.

[0026] The pressing mechanism 2 further includes a second connecting seat 22 connected to the guide post 11 and a lower pressing seat 23 connected to the second connecting seat 22. The lower pressing member 21 is connected to the lower pressing seat 23. The lower pressing seat 23 is specifically a guide sleeve, which makes the pressing mechanism 2 move more smoothly.

[0027] A positioning post 12 is provided on the base 1. Locking components 6 are provided on both the first connecting seat 31 and the second connecting seat 22. Each locking component 6 includes a locking seat 61 and a locking fastener 62 movably connected to the locking seat 61. The positioning post 12 passes through the locking seat 61 and the locking fastener 62. The positioning post 12 has several locking grooves 13 that mate with the locking fastener 62. Multiple locking grooves 13 can be provided according to actual needs, such as at positions where the pressing mechanism 2 or the pressing guide mechanism 3 needs to be fixed. The locking fastener 62 has a locking hole with a diameter larger than that of the positioning post 12. When the locking fastener 62 moves to a position corresponding to the locking groove 13, pushing the locking fastener 62 towards the locking groove 13 allows the wall of the locking hole to be inserted into the locking groove 13. Thus, the engagement of the locking groove 13 and the locking fastener 62 limits the movement of the first connecting seat 31 / second connecting seat 22.

[0028] The bottom of the locking seat 61 is provided with a groove 63, and the locking fastener 62 is inserted into the groove 63. The groove 63 plays a guiding and limiting role for the locking fastener 62, ensuring that the lock hole wall of the locking fastener 62 can be accurately inserted into the buckle groove 13.

[0029] One end of the locking fastener 62 is provided with a push plate 64, which allows the user to push and pull the locking fastener 62 to quickly lock or release it.

[0030] A support column is provided on the base 1, and a top plate 15 is provided on the top of the support column. The top ends of the guide column 11 and the positioning column 12 are both connected to the bottom of the top plate 15. In this embodiment, two support columns are provided, and the support columns and the top plate 15 form a fixing frame to ensure the stability of the guide column 11 and the positioning column 12.

[0031] The pressing drive mechanism 5 includes a column 51 mounted on the base 1 and a pressure rod 52 rotatably connected to the top of the column 51 at one end. The pressure rod 52 is located above the lower pressure member 21. A pressing part 53 is provided on the bottom surface of the pressure rod 52 corresponding to the lower pressure member 21. When the pressure rod 52 presses down, the pressing part 53 contacts the lower pressure member 21 of the pressing mechanism 2, pushing the lower pressure member 21 downwards. When the pressing part 53 contacts the lower pressure member 21, the column 51 and the pressure rod 52 form a lever structure, making the pressing process more effortless.

[0032] The positioning fixture 4 includes a positioning base 41 and several support portions 42 disposed on the positioning base 41 for positioning the PCB. Since the PCB used in the assembly process of this application is rectangular, four support portions 42 are provided, corresponding to the four corners of the PCB respectively. Each support portion 42 has a recessed portion at its top to accommodate the PCB and to limit its movement while supporting it.

[0033] During assembly, the pressing mechanism 2 and pressing guide mechanism 3 are positioned above the guide post 11 and locked by the locking component 6, thus creating space for the circuit board. The PCB is then placed onto the positioning fixture 4. Next, the pressing guide mechanism 3 is unlocked and moved downwards, allowing the guide seat 32 to reach above the PCB (the positioning post 12 can have a corresponding slot 13). The terminals are then inserted into the pre-set guide holes 34 of the auxiliary positioning block. After all terminals are inserted into the guide holes 34, the pressing mechanism 2 is unlocked and moved downwards, causing the lower pressing member 21 to contact the top of the terminals. The pressure rod 52 is then pressed downwards, causing the lower pressing member 21 to continue moving downwards, simultaneously pressing all terminals into their corresponding positions on the PCB, completing the terminal insertion. Finally, the pressing mechanism 2 and pressing guide mechanism 3 are reset, and the PCB can be removed. The terminal insertion process is straightforward, and with the help of the auxiliary positioning block, accurate positioning is achieved without damaging the terminals or the PCB.

[0034] The process of using this utility model mainly relies on manual operation and does not involve automated structures, which makes the processing and manufacturing cost of this utility model relatively low and suitable for assembling test samples during laboratory development and design.
