Description

Miniaturized connector

Technical Field

The utility model belongs to the field of connectors, and particularly relates to a miniaturized connector.

Background

With the unprecedented growth of data demands of communication networks such as 5G, data centers, etc., how to achieve higher rate and capacity transmission in limited space is a continuing challenge for each network equipment provider, high-density deployment is the most straightforward solution, i.e., connectors, adapters, optical modules are reduced in size, the number of cores is increased, and more modules and connectors are deployed in limited space.

In the current communication system, LC, duplex LC fiber optic connectors (as shown in fig. 1, 2 LC connectors are used to secure together) are the most widely used.

As shown in fig. 3, the principle of plugging the LC type adapter and duplex connector (hereinafter described as a plug) is as follows:

(1) Plug insertion locking process: the LC connector 1 has wings 3, and by pushing the plug into the adaptor, bosses 4 on the wings 3 compress resiliently downward and then spring automatically into steps 5 on the LC adaptor; at the moment, the plug cannot be directly pulled out, so that automatic locking is formed;

(2) The plug unlocking and pulling-out process comprises the following steps: the pressure plate 6 of the LC connector must be pressed by hand to compress the boss 4 on the wing 3 downward and away from the step 5 of the adapter, releasing the locking of the LC adapter and the plug, and pulling the plug by hand at the same time, the plug and the adapter are smoothly separated.

The disadvantages of the above prior art are:

1. the plug is inserted into the adapter by pushing in directly by hand, pulling out the pressing plate 6 which is necessary to press the plug, and simultaneously pinching the plug to pull out the plug. The pressing plate 6 must be pressed to ensure a certain distance, the amplitude is too small, and unlocking cannot be realized; the operation is inconvenient.

2. The wing for locking moves in the vertical direction and is inconvenient to operate: the plug is inserted into the adapter by pushing in directly by hand, pulling out the pressing plate 6 which is necessary to press the plug, and simultaneously pinching the plug to pull out the plug. Pressing the press plate 6 by hand must ensure a certain operation space, and the connector cannot be deployed at high density. Typically, achieving locking and unlocking requires that the connector be provided with an active space of not less than 6.8mm in the vertical direction, such as 7.25mm in fig. 3.

3. The two optical fibers of the duplex LC connector are respectively provided with a shell, so that the distance between the two optical fibers is 6.25mm (as shown in fig. 2), the distance is larger, a certain transverse direction space is occupied, and the requirement of high-density deployment cannot be well met.

Disclosure of Invention

The utility model aims to provide a miniaturized connector, which realizes the butt joint of two or more optical fiber ferrules by improving the structure, wherein the distance between the two optical fiber ferrules is less than or equal to 3.1mm, and simultaneously the push-pull plug of the tail part is realized by a push-pull locking structure without occupying the vertical space, so that the size of the connector is smaller, and the installation and operation space of the connector is greatly saved.

In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: a miniaturized connector comprises a front shell, a rear shell, a tail sheath and a pin component, wherein a first accommodating hole, a second accommodating hole and a third accommodating hole are formed in the front side and the rear side of the front shell at intervals; a slide way for unlocking the connector and the adapter is arranged in the front shell at the first accommodating hole; the front section of the rear shell is provided with two elastic arms which extend outwards in an inclined mode, the contact pin component is assembled between the two elastic arms, the tail end of each elastic arm is provided with a locking spring claw which can be matched with a locking hole of the adapter for use, the locking spring claw is exposed out of the front shell through a first containing hole, and the rear section of the rear shell is provided with a convex claw which is used for being clamped in the second containing hole; and a connecting piece matched with the third accommodating hole is arranged on the tail sheath.

The side of locking spring claw sets up the sliding key, in the unblock in connector and adapter, the slide extrusion sliding key makes the elastic arm to the connector inboard deformation.

The slideway is arranged at the front section of the first accommodating hole and is positioned at one side or two sides of the first accommodating hole.

The rear section of the rear shell is provided with a deformation groove, so that an elastic plate capable of deforming inwards is formed on the side face of the rear section of the rear shell, and the convex claw is arranged on the elastic plate.

And an unlocking pull ring is further arranged on the tail sheath.

At least two contact pin parts are arranged and are arranged in the assembly grooves of the rear shell side by side.

A polarity member mounting shaft for mounting the polarity adjusting member is arranged in the front housing.

The polar piece installation shafts are arranged on two sides of the front end opening of the front shell.

The side face of the polarity adjusting part is opened so as to be convenient to assemble and disassemble on the polarity part mounting shaft.

The beneficial effects of the utility model are as follows: 1. the connector provided by the utility model can be directly locked and unlocked with the adapter through pushing and pulling, and only the connector is required to be pushed forward during insertion; when the device is pulled out, the tail sheath or the pull ring can be pulled out directly from the tail, so that the operation space in the height direction is saved, and the device is convenient for high-density deployment and narrow space operation.

2. The connector has the advantages that the size is reduced, the distance between the two pins is less than or equal to 3.1mm, and the high-density deployment is convenient.
