Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and more particularly to a splint-type double-position traceless connector. Background Art

[0002] Many storage products, such as memory modules, M.2 SSDs, mSATA SSDs, E1.S enterprise-class SSDs, and E3.S enterprise-class SSDs, use circuit board gold finger interfaces to connect to devices. While these gold finger interfaces offer high density and excellent electrical performance, they are also susceptible to scratches and wear. In normal use, with minimal plugging and unplugging, these scratches and wear can be ignored. However, during factory testing, repeated plugging and unplugging can leave scratches and wear that seriously affect the appearance.

[0003] Traditional connectors are primarily categorized as vertical or horizontal. Vertical plugging is simpler and saves space, but it also results in significant wear and tear. To mitigate wear and accommodate the increased density of gold fingers, horizontal plug-in connectors were invented. These connectors are inserted at an angle and then pressed flat to lock. While this reduces wear, the spring contacts still slide slightly during the flattening process. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the utility model provides a splint-type double-position seamless connector, which solves the problem that the gold fingers of the circuit board are scratched and worn due to frequent plugging and unplugging during testing of the existing connector, thereby achieving seamless plugging and unplugging and optimizing the user experience.

The second pusher is located between the spring pin inside the first slot and the spring pin inside the second slot.

[0007] The pushing mechanism includes a pressure rod, a metal rod and a metal part; the pressure rod is rotatably connected to the metal rod and is located on one side of the connector body; the metal rod is close to the bottom of the second pushing member; the metal part is fixedly installed at the bottom of the second pushing member and is close to the metal rod.

[0008] In the above structure, a top limiter and a bottom limiter are further provided inside the connector body; the top limiter is fixed to the top of the spring pin, and the first pusher is slidably connected between the top limiter and the bottom limiter.

[0009] In the above structure, a through slot is provided on one side of the bottom stopper close to the first slot / the second slot, and a welding foot is provided at the bottom; the bottom of the spring pin passes through the through slot and is welded to the welding foot.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0021] Reference Figure 1 and Figure 2 As shown, the utility model discloses a splint-type double-position seamless connector, which includes:

[0022] The connector body has a first slot 1 and a second slot 2 at the top, and a spring pin 8, a first pusher 3, and a second pusher 4 inside. The spring pin 8 is located on the inner side of the first slot 1 and the inner side of the second slot 2. The first pusher 3 is close to the side of the spring pin 8 on the outer side of the first slot 1. The second pusher 4 is located between the spring pin 8 on the inner side of the first slot 1 and the spring pin 8 on the inner side of the second slot 2.

[0023] The pushing mechanism includes a pressure rod 5, a metal rod 6 and a metal part 7; the pressure rod 5 is rotatably connected to the metal rod 6 and is located on one side of the connector body; the metal rod 6 is close to the bottom of the second pushing member 4; the metal part 7 is fixedly installed at the bottom of the second pushing member 4 and is close to the metal rod 6.

[0024] It should be noted that, in this embodiment, the connector body is the basic structure of the entire splint-type double-position seamless connector, wherein the first slot 1 and the second slot 2 provided on the top of the connector body are used to install the circuit board and electrically connect with the circuit board; the spring pins 8 are key components for electrically connecting the splint-type double-position seamless connector with the circuit board, and are distributed on the inner sides of the first slot 1 and the second slot 2. They are made of elastic metal material and can generate elastic deformation after the components are inserted to contact with the gold fingers of the circuit board to ensure good electrical connection; the first pusher 3 is used to push The spring pins 8 on the outside of the first slot 1 apply a thrust to help the spring pins 8 on both sides of the first slot 1 contact with the gold fingers of the inserted circuit board; the second pusher 4 is used to apply pressure to the spring pins 8 on the inside of the second slot 2 to help the spring pins 8 on both sides of the second slot 2 contact with the gold fingers of the inserted circuit board; the pushing mechanism is used to apply power to the second pusher 4 so that the second pusher 4 pushes the spring pins 8 on the inside of the second slot 2 to approach the circuit board in the second slot 2; specifically, by applying pressure to the pressure rod 5, the pressure rod 5 rotates, driving the metal rod 6 to push the metal part 7, and then driving The second pushing member 4 pushes the spring pin 8 on the inner side of the second slot 2 to approach the circuit board in the second slot 2; in the specific implementation of the present invention, the user first inserts the gold fingers of the two circuit boards into the first slot 1 and the second slot 2 respectively. Since the spacing between the spring pins 8 on both sides of the first slot 1 and the second slot 2 is slightly larger than the thickness of the circuit board, the gold fingers of the circuit board do not contact the spring pin 8 at this time, and the insertion of the circuit board will not cause scratches on the surface of the gold fingers; then, by pushing the pushing block, the spring pin 8 on the outer side of the first slot 1 is moved closer to the circuit board in the first slot 1, so that the spring pins on both sides of the first slot 1 The spring pin 8 clamps the circuit board in the first slot 1; and by operating the pushing mechanism, that is, by applying pressure to the pressure rod 5, the pressure rod 5 rotates, driving the metal rod 6 to push the metal part 7, and then driving the second pushing part 4 to push the spring pin 8 on the inside of the second slot 2 close to the circuit board in the second slot 2 so that the spring pins 8 on both sides of the second slot 2 clamp the circuit board in the second slot 2; in this process, when inserting the gold finger of the circuit board, the gold finger of the circuit board does not need to rub against the spring pin 8, so as to avoid scratches and wear caused by repeated plugging and unplugging during testing, thereby achieving seamless plugging and unplugging and optimizing the user experience.

[0025] Reference Figure 1 As shown, a top limiter 9 and a bottom limiter 10 are further provided inside the connector body; the top limiter 9 is fixed to the top of the spring needle 8, and the first pusher 3 is slidably connected between the top limiter 9 and the bottom limiter 10.

[0026] It should be noted that, in this embodiment, the top limit member 9 is used to fix the top of the spring needle 8, and the bottom limit member 10 is used to fix the bottom of the spring needle 8; and the top limit member 9 and the bottom limit member 10 located on the outside of the first slot 1 together play the role of upper and lower limits on the first push member 3; the top limit member 9 and the bottom limit member 10 located between the first slot 1 and the second slot 2 together play the role of upper and lower limits on the second push member 4.

[0027] Reference Figure 1 As shown, the bottom limiter 10 is provided with a through slot on one side close to the first slot 1 / the second slot 2 , and a welding foot 12 is provided at the bottom; the bottom of the spring needle 8 passes through the through slot and is welded to the welding foot 12 .

[0028] It should be noted that, in this embodiment, the bottom of the shrapnel needle 8 is a right-angled fold line structure, and the top vertical line of the right-angled fold line passes through the through groove. The bottom L-shaped structure is clamped at the bottom of the bottom limit member 10 and is welded and fixed to the bottom of the bottom limit member 10 with the welding foot 12; in addition, the L-shaped structure at the bottom of the shrapnel needle 8 is staggered and fixed in the front and back, which can reduce the difficulty of welding and indirectly increase the density of the shrapnel needle 8.

At this time, the metal rod 6 is in contact with the metal part 7 and applies a pressure to the metal rod 6 that is close to the second slot 2, so as to drive the second pushing member 4 to move toward the spring needle 8 inside the second slot 2, and push the spring needle 8 inside the second slot 2 close to the circuit board in the second slot 2 so that the spring needles 8 on both sides of the second slot 2 clamp the circuit board in the second slot 2.

[0039] Reference Figure 1 As shown, the first slot 1 and the second slot 2 are arranged parallel to each other, and the size of the first slot 1 is adapted to the size of the second slot 2.

[0040] It should be noted that, in this embodiment, the first slot 1 and the second slot 2 are designed to be parallel to each other to ensure that tilting or misalignment of the circuit board is avoided during the insertion process, and to ensure precise docking between the circuit board and the connector; and the sizes of the first slot 1 and the second slot 2 are adapted to ensure precise contact between the circuit board and the spring pin 8 inside the connector, so as to improve the stability of the connection and reduce the possibility of poor contact.
