Description

Technical Field

[0001] This utility model relates to a modular and expandable pin header connector, belonging to the field of pin header technology. Background Technology

[0002] Pin headers are a type of connector product, often referred to as universal connectors. With increasing competition in the connector market, pin headers are now widely used in PCB circuit boards in electronics, electrical appliances, and instrumentation. They are typically used with female headers to create board-to-board connections, or with electronic wire harness terminals to create board-to-wire connections. They can also be used independently for board-to-board connections. Traditional pin headers lack expandability and have limited shock resistance. Utility Model Content

[0003] The purpose of this invention is to provide a modular and expandable pin header connector to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a modular expandable pin header connector, including a plastic base, pins, a combined stabilizing insert, mating protrusions, mating grooves, locking and damping blocks, and a pin header nut. The plastic base and pins are installed as a single unit. The mating protrusions and mating grooves of the plastic base are integrally injection molded and positioned by the combined stabilizing insert. The locking and damping blocks are installed at both ends of the plastic base and the pin header nut.

[0005] Preferably, the upper end of the plastic base is machined with a mating insertion hole.

[0006] Preferably, the combined stabilizing rod consists of a support rod and threaded anti-slip rubber sleeves, with threaded anti-slip rubber sleeves fitted at both ends of the support rod.

[0007] Preferably, the locking vibration damping block is composed of a U-shaped bracket, locking screws, an inner rectangular buffer groove, anti-slip rubber washers, and a central horizontal stabilizing pad. Locking screws are threaded onto both ends of the U-shaped bracket. Inner rectangular buffer grooves are machined into the inner sides of both ends of the U-shaped bracket. The anti-slip rubber washers installed inside the inner rectangular buffer grooves are positioned and installed by independent rotating shafts and locking screws.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] The plastic seat mating protrusion and mating groove can be combined and installed with a stable plug rod to achieve a modular expansion design and realize a combination adjustment design for different pin specifications.

[0010] The locking vibration damping block consists of a U-shaped bracket, locking screws, an inner rectangular buffer groove, anti-slip rubber washers, and a central horizontal stabilizing pad. After the plastic base is connected to the nut, it is secured by the locking vibration damping block. The locking screws tighten and fix the anti-slip rubber washers. When vibration occurs, the anti-slip rubber washers deform and move slightly up and down in the inner rectangular buffer groove, which has a good positioning, fixing and damping effect.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] like Figures 1-5 As shown, a modular and expandable pin header connector includes a plastic base 1, pins 2, a combination stabilizing insert 3, mating protrusions 4, mating grooves 5, locking and damping blocks 6, and a female connector 7. The plastic base 1 and pins 2 are integrally installed. The mating protrusions 4 and mating grooves 5, which are integrally injection molded on the plastic base 1, are positioned and installed by the combination stabilizing insert 3. The locking and damping blocks 6 are installed at both ends of the plastic base 1 and the female connector 7.

[0019] The upper end of the plastic base 1 is machined with a mating hole 8.

[0020] The combined stabilizing insert 3 consists of a support insert 9 and a threaded anti-slip rubber sleeve 10. The threaded anti-slip rubber sleeve 10 is fitted at both ends of the support insert 9. The support insert 9 is inserted and fixed by inserting through the through hole of the docking protrusion 4 and the docking groove 5. The threaded anti-slip rubber sleeve 10 has good anti-slip performance to prevent the support insert 9 from slipping and loosening.

[0021] The locking and vibration damping block 6 consists of a U-shaped bracket 11, locking screws 12, an inner rectangular buffer groove 13, anti-slip rubber washers 14, and a central horizontal stabilizing washer 15. Locking screws 12 are threaded onto both ends of the U-shaped bracket 11. Inner rectangular buffer grooves 13 are machined into the inner sides of both ends of the U-shaped bracket 11. Anti-slip rubber washers 14 are installed inside the inner rectangular buffer grooves 13 and positioned and installed with the locking screws 12 via independent rotating shafts. Tightening the locking screws 12 secures the anti-slip rubber washers 14. When vibration occurs, the anti-slip rubber washers 14 deform and move slightly up and down in the inner rectangular buffer grooves 13, providing a good positioning, fixing, and vibration damping effect. At this time, the plastic seat 1 and the nut 7 are fixed and stable. The horizontally welded central horizontal stabilizing washer 15 improves the structural strength of the U-shaped bracket 11.

[0022] Specific usage: A modular and expandable pin header connector, the plastic base mating protrusion and mating groove are combined and installed by a combination of stabilizing plug rods to achieve a modular expansion design that allows for the combination and adjustment of different pin specifications. After the plastic base is connected to the pin header, it is connected by a locking shock-absorbing block. The locking screw tightens and fixes the anti-slip rubber washer. When vibration occurs, the anti-slip rubber washer deforms and moves slightly up and down in the inner rectangular buffer groove, which has a good positioning, fixing and shock absorption effect. The central horizontal stabilizing pad is horizontally positioned and welded to improve the structural strength of the locking shock-absorbing block and prevent deformation.

[0023] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
