Description

Technical Field

[0001] This utility model relates to the field of spring clip technology, and in particular to a novel AC contact spring clip. Background Technology

[0002] AC stands for alternating current. AC contact spring clips are used in chargers, power supplies, adapters, etc., to connect the electronic circuit board and AC plug to conduct AC power. They are soldered to the circuit board through plugs to connect the power plug and the circuit board and conduct power.

[0003] Currently, the commonly used AC contact springs are inserted into circuit boards manually or using a custom-made spring insertion machine. This custom-made spring insertion machine must be used in conjunction with a commercially available automated AI insertion machine; using it alone results in extremely low efficiency. The automated AI insertion machine, on the other hand, does not require a custom-made spring insertion machine. The following two assembly and processing methods have significant drawbacks:

[0004] 1) Manual insertion is extremely slow, requires a large amount of manpower, and involves applying considerable force, leading to fatigue and even skin irritation to workers' fingers (see appendix for details). Figure 6 );

[0005] 2) Currently, the dedicated spring inserting machine is also unstable in operation because the size of the AC contact spring clip structure is inconsistent in batches. It still requires manual operation, and the efficiency has not been significantly improved. Moreover, it is difficult for employees to debug it themselves. It still requires professional technicians to debug it, which often leads to machine downtime and waiting for professional technicians to come to debug it. Therefore, the efficiency has not been significantly improved.

[0006] Therefore, we propose a new type of AC contact spring clip that can be used with existing automated tape and reel machines or customized dedicated automated tape and reel machines. Users can use existing automated AI insertion machines on the market without the need for customized dedicated automated AI insertion machines. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology. After the product is improved, it can be used with existing automated tape-making machines on the market or customized automatic tape-making machines to directly tape the tapes and deliver them to customers. Customers can use existing automated AI insertion machines on the market to insert the tapes, without the need to customize a dedicated automatic AI insertion machine, thus saving on equipment customization costs and maintenance costs.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A novel AC contact spring clip includes an AC contact spring clip body, which is composed of an upper connecting crossbar, a middle connecting crossbar, a lower connecting crossbar, a working section, pins, and a tape section. The AC contact spring clip is formed into an integral structure by continuous stamping and bending of a flat strip.

[0010] The working section is connected between the upper connecting crossbar and the middle connecting crossbar, the pin is connected between the middle connecting crossbar and the lower connecting crossbar, and the tape section is connected to the lower connecting crossbar away from the pin end.

[0011] The working section consists of two symmetrical shaped bending pieces, with different widths at both ends of the two shaped bending pieces, forming an insertion port and a clamping port.

[0012] Furthermore, the upper connecting crossbar, the middle connecting crossbar, and the lower connecting crossbar all have rectangular cross-sections, with one end open and the open ends facing the same direction, and the included angle away from the open end is chamfered.

[0013] Furthermore, the number of pins is two symmetrically arranged, and the two ends of the two pins are respectively connected to the symmetrical sides of the middle connecting crossbar and the lower connecting crossbar. The two ends of the formed bending piece are respectively connected to the symmetrical sides of the upper connecting crossbar and the middle connecting crossbar.

[0014] Furthermore, the center point of the formed bending piece extends to one end, and the extended end expands outward to form an insertion port; the center point of the formed bending piece tightens to the other end, and the extended end expands outward to form a clamping port.

[0015] Furthermore, the center point of the formed bending piece extends to one end, forming a guide opening opposite the slots of the upper connecting crossbar and the middle connecting crossbar.

[0016] Furthermore, the width of the insertion port and the guide port is greater than the thickness of the pin, and the width of the clamping port is less than the thickness of the pin.

[0017] Furthermore, the pin is 10mm long.

[0018] Furthermore, the braiding segment is used by the braiding machine to bond between the paper carrier tape and the adhesive tape.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] By improving the AC contact spring clip structure, automated insertion into the circuit board can be achieved without jamming, ensuring stable operation, reducing downtime for debugging, and eliminating the need for manual insertion into the circuit board. The automatic insertion of tape and reel is 5 times more efficient than manual insertion, which can significantly reduce labor costs and greatly improve production efficiency.

[0032] Example 1

[0033] like Figure 1-4 As shown, this utility model provides a technical solution: a novel AC contact spring clip, comprising an AC contact spring clip body, which is composed of an upper connecting crossbar 1, a middle connecting crossbar 2, a lower connecting crossbar 3, a working section 4, pins 5, and a tape section 6. The AC contact spring clip is formed into an integral structure by continuous stamping and bending of flat strip material, without welding or riveting processes; the working section 4 is connected between the upper connecting crossbar 1 and the middle connecting crossbar 2, and the pins 5 (plugs or pins) are connected between the middle connecting crossbar 2 and the lower connecting crossbar 3, ensuring that the distance between the two pins is stable and does not deform or skew during stamping, electroplating, tape bonding, and insertion processes; the tape section 6 is connected to the lower connecting crossbar 3 at the end away from the pins 5.

[0034] Through the above embodiments, the working section 4, pin 5 and tape section 6 are connected in the same direction with the crossbar to form the new AC contact spring clip.

[0035] Furthermore, the working section 4 consists of two symmetrical forming bending pieces 41, with different widths at both ends of the two forming bending pieces 41, forming an insertion port 42 and a clamping port 43.

[0036] Correspondingly, the cross-sections of the upper connecting crossbar 1, the middle connecting crossbar 2, and the lower connecting crossbar 3 are all rectangular, with one end open and the open ends facing the same direction, and the included angle away from the open end is chamfered.

[0037] To enable the working section 4 and pin 5 to connect with the upper connecting crossbar 1, the middle connecting crossbar 2 and the lower connecting crossbar 3, and to form a guide opening 44, the number of pins 5 is symmetrically two. The two ends of the two pins 5 are respectively connected to the symmetrical sides of the middle connecting crossbar 2 and the lower connecting crossbar 3. The two ends of the formed bending piece 41 are respectively connected to the symmetrical sides of the upper connecting crossbar 1 and the middle connecting crossbar 2.

[0038] Example 2

[0039] like Figure 1-4As shown, the center point of the forming bent piece 41 extends to one end, and the extended end expands outward to form an insertion port 42. The center point of the forming bent piece 41 tightens to the other end, and the extended end expands outward to form a clamping port 43. The center point of the forming bent piece 41 extends to one end and forms a guide port 44 opposite to the slots of the upper connecting crossbar 1 and the middle connecting crossbar 2.

[0040] The insertion port 42 and guide port 44 are wider than the pin thickness, which facilitates smooth assembly of the finished product and provides guidance. The clamping port 43 is narrower than the pin thickness, forming a clamping opening to clamp the assembled pin and ensure reliable conductivity.

[0041] It should be noted that pin 5 is approximately 10mm long;

[0042] The braiding segment 6 is used by the braiding machine to bond between the paper carrier tape and the bonding tape, ensuring that the braiding is stable, does not deviate, and is tightly bonded without falling off or skewing. It can be used with general market braiding machines or customized special braiding machines. It is not needed during the insertion process (the braiding segment 6 is cut off).

[0043] The working process of this utility model (installation of the AC contact spring clip and circuit board): First, the components are conveyed to the tape guide rail (automatic tape feeding) via a vibratory feeder or other means. This can be done using a general market tape feeding machine or a customized dedicated tape feeding machine. The tape segment 6 is then bonded between the paper carrier tape and the bonding tape, and fed into the automatic AI insertion machine (automatic insertion machine for reducing feet and inserting components). A general market automatic AI insertion machine does not require a separately customized insertion machine (e.g., ...). Figure 5 (as shown);

[0044] The automated AI insertion machine process involves two lead trimming steps:

[0045] ① Automatic insertion machine lead trimming: The first lead trimming leaves a lead length of about 7.0mm to 9.0mm. Remove the unnecessary tape carrier and excess length of pin 5 (pin or pin). Hold the 7.0mm pin 5 (pin or pin) until it is inserted into the circuit board station;

[0046] ② Automatic insertion machine for cutting leads and inserting leads: The automatic AI insertion machine automatically inserts leads into the circuit board. The second lead cutting is done after insertion into the circuit board. The insertion machine bends the spring contact pin 5 (pin or PIN) that passes through the circuit board to ensure that it is firmly attached to the circuit board and does not fall off. At the same time, it cuts off the excess length of pin 5 (pin or PIN). Finally, the length of pin 5 (pin or PIN) on the spring contact on the inserted circuit board is about 3.0 to 4.0 mm.

[0047] It should be added that pin 5 (pin or connector) needs to be extended during the tape and reel manufacturing process.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
