Description

Uninterrupted power connector

Technical Field

The utility model belongs to the technical field of power connector technique and specifically relates to an uninterrupted power connector.

Background

A power connector is a commonly used type of connection component in electronic devices, and is generally used to connect two active devices and transfer current or signals between the two. The prior art power connector mainly includes the following two forms.

Chinese patent document CN 209249750U discloses a pogo pin connector that can be quickly detached and replaced. Its structure is as shown in figure 1, including syringe needle, needle tubing, tension spring and base, syringe needle and needle tubing, tension spring riveting are as an organic whole, and the setting of syringe needle and tension spring activity is in the needle tubing, the base sets up on PCB, and the lower extreme detachable of needle tubing sets up on the base, and the lower terminal surface of syringe needle sets up to the inclined plane, and tension spring is connected with needle tubing with the needle tubing respectively, and the needle tubing setting is stretched out to the upper end of syringe needle, and the axial concertina movement of needle tubing can be followed to the syringe needle. The technical scheme of the utility model can realize the change of spring probe connector on same base, need not whole change spring probe connector to simplify the operation of changing the connector, convenient and fast has improved efficiency, the cost is reduced.

Chinese patent document CN 209183822U discloses a spring probe connector structure without a needle tube. The structure of the needle shaft is as shown in fig. 2, and the needle shaft comprises a metal conductor, and a plurality of needle shafts and tension springs which are arranged in the metal conductor, wherein the tension springs are respectively connected with the needle shafts and the metal conductor, the upper end of each needle shaft extends out of the metal conductor, and the needle shafts move in a telescopic manner along the height direction of the metal conductor. The technical scheme of the utility model can be with the direct assembly of needle axle in metal conductor, do not need solitary needle tubing, it is more convenient to assemble, and save material has improved work efficiency simultaneously to simple structure, design benefit, the equipment of spring probe connector is convenient, and production efficiency is high, and this spring needle connector's conducting current is big, satisfies the requirement that the heavy current charges, and the practicality is strong, is fit for popularizing and applying.

However, the prior art power connectors are all in the form of an innerspring. The needle is indirectly connected with the base through a spring or is connected with the base through a friction surface between the needle and the base. According to the structure, the two connecting points are added due to the indirect connection of the spring, so that the internal resistance is increased and unstable, the spring is annealed due to heating caused by electrification and loses elasticity, and the good contact between the needle head and a measured point cannot be ensured. Further, the friction surface connection increases the gap and also increases the internal resistance after a long time use, and the connection reliability is lowered.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an uninterrupted power connector for solve the technical problem who improves the connection reliability.

The utility model provides a technical scheme that its technical problem adopted is:

an uninterrupted power connector comprises a needle shaft, a spring and a base, wherein the base is provided with a base hole which is through up and down; the needle shaft is connected with the base through a spring.

Furthermore, an insulating sliding sleeve is arranged in the base hole, and the needle shaft penetrates through the insulating sliding sleeve.

Further, the spring is arranged between the upper part of the needle shaft and the upper part of the insulating sliding sleeve.

Furthermore, the insulating sliding sleeve is connected with the base through a fixing screw.

Furthermore, the lower part of the needle shaft is connected with the insulating sliding sleeve through a locking ring.

Furthermore, the locking ring is connected in a riveting or bonding manner.

The effects provided in the contents of the present invention are only the effects of the embodiments, not all the effects of the present invention, and the above technical solutions have the following advantages or beneficial effects:

the spring and the needle shaft are arranged externally, the head of the needle shaft is in contact with a measured point, the tail of the needle shaft can adopt a tubular terminal or a welding connection wire, the middle of the needle shaft is reduced in connection media and contact points, internal friction and spring contact points do not exist, and connection reliability is improved.

Detailed Description

In order to clearly illustrate the technical features of the present invention, the present invention is explained in detail by the following embodiments in combination with the accompanying drawings. It should be noted that the components illustrated in the figures are not necessarily drawn to scale. Descriptions of well-known components and techniques are omitted so as to not unnecessarily limit the invention.

As shown in fig. 1, an uninterruptible power supply connector includes a needle shaft 1, a spring 2, an insulating sliding sleeve 3, a base 4, a locking ring 5, and a fixing screw 6. The base 4 is provided with a plurality of base holes which are communicated up and down, and the insulating sliding sleeves 3 are respectively arranged in the base holes. The side of the base 4 is provided with a fixing screw hole communicated with the base hole, and the fixing screw 6 is installed in the fixing screw hole in a matching way and used for jacking and fixing the insulating sliding sleeve 3 in the base hole. The needle shaft 1 is vertically arranged on the base 4 through the insulating sliding sleeve 3, and the spring 2 is sleeved between the upper part of the needle shaft 1 and the upper end of the insulating sliding sleeve 3; the locking ring 5 is arranged between the lower part of the needle shaft 1 and the lower end of the insulating lantern ring 3; the locking ring 5 is riveted or bonded on the needle shaft 1.

When the device is used, the head of the needle shaft 1 is used for contacting a measured point, the tail of the needle shaft 1 is connected with a soft lead through a tubular terminal or welding, and when the head of the needle shaft 1 is subjected to axial pressure, the needle shaft 1 slides in the insulating sliding sleeve 3 and under the elastic action of the spring 2, so that the needle shafts 1 can be ensured to be in good contact with the measured point, and current or voltage signals are transmitted.

In addition to the technical features described in the specification, the technology is known to those skilled in the art.

Although the specific embodiments of the present invention have been described with reference to the drawings, the present invention is not limited thereto, and various modifications or variations that can be made by those skilled in the art without inventive labor are still within the scope of the present invention.
