Description

Technical Field

[0001] The invention relates to a separation connector with multi-stage compensation and self-locking functions, which can perform multi-stage compensation during docking and plugging, and can self-lock to prevent rebound after separation, belonging to the technical field of electrical connectors. Background Art

[0002] The separation connector with multi-level compensation and self-locking functions is used for connection within the weapon system. When installed in a certain space, the separation connector needs to have multi-level automatic compensation capabilities and quick locking and separation functions. After unlocking and separating, the separation plug can quickly deviate from the plug-in position, and automatically lock after reaching the limit point to prevent rebound, thereby avoiding collision with the moving body after rebound.

[0003] Compared with the disclosed patent (publication number: CN101494347A) "An error-compensating separation electrical connector", the original patent can only perform single-stage compression compensation and has certain requirements on the size of the operating space. The present patent uses multi-stage compression compensation and a snap-on structure, which can achieve installation and use in a smaller space; secondly, after the original patent is separated, after the pull-out mechanism rotates to the limit point, due to the fast speed, it will rebound when it hits the limit point. The present patent adds a snap-on structure to realize the self-locking function, so that the pull-out mechanism automatically locks after reaching the limit point, and the separated plug is prohibited from rebounding. Summary of the invention

[0004] The object of the present invention is to provide a separable electrical connector which can be used and operated in a narrow space and has multi-level compensation and self-locking functions after separation, so as to overcome the shortcomings of the prior art.

[0005] In order to meet the above purpose, the present invention adopts the following technical solution:

[0006] A separation connector includes a support and pull mechanism, which includes a length compensation structure along its own axial direction. The length compensation structure is composed of at least two length compensation structures connected in series, and when the compensation amount of one of the length compensation structures reaches the compensation limit, the remaining length compensation structures start length compensation in turn.

[0007] Furthermore, the length compensation structure is at least two coaxial and mutually sleeved hollow tubular structures, wherein a spring is arranged inside the hollow tubular structure along the axis direction of the hollow tubular structure. The sleeve connection here means that one hollow tube is inserted into the inside of another hollow tube.

[0008] Furthermore, when the number of the length compensation structures is greater than 3, the outer diameters of the different hollow tubular structures increase or decrease step by step from one end to the other end of the length compensation structure. For example, when there are 3 length compensation structures, the outer diameter of the first length compensation structure is the smallest, the outer diameter of the second length compensation structure is in the middle, and the outer diameter of the third length compensation structure is the largest, so that the series compensation structure formed has higher stability.

[0009] Furthermore, the compensation amounts of different length compensation structures are different, and the compensation amount of the length compensation structure located at the end is the largest.

[0010] Furthermore, the pulling mechanism further comprises a buckle structure, which is activated and fixes the pulling mechanism after the separation socket is separated from the separation plug.

[0011] Further, the buckle structure includes:

[0012] A through hole located on the rotating seat of the pulling mechanism;

[0013] A groove located on the base of the supporting mechanism;

[0014] A buckle is placed in the groove and inserted into the hole after the separation socket is separated from the separation plug.

[0015] Furthermore, a spring mounting column is provided in the groove, a spring is sleeved on the outer side of the spring mounting column, and one end of the spring is connected to the buckle.

[0016] Furthermore, one end of the buckle has a cylindrical hole, and the other end is a head with an arc-shaped surface.

[0017] Furthermore, there are two buckles, which are distributed on a straight line perpendicular to the end surfaces on both sides of the rotating base.

[0018] Furthermore, it also includes an unlocking sleeve, which is located on the side end surface of the rotating seat of the supporting mechanism, and one end of the unlocking sleeve is connected to the rotating shaft of the supporting mechanism; a protrusion is provided on the unlocking sleeve and pointing to the through hole position of the rotating seat of the supporting mechanism, and the outer diameter of the protrusion is smaller than the through hole.

[0019] Compared with the prior art (i.e., the patent publication number is CN101494347A, the publication date is May 2, 2012, and the invention name is an invention patent for an error-compensating separation electrical connector), the advantages of the present invention are as follows:

[0020] a) The present invention uses a multi-stage compensation technology, which has a larger compensation distance under the same external dimensions compared to the single-stage compensation of the connector in the prior art;

[0021] b) The present invention adds a snap structure. After the separable socket and the separable plug are separated, the snap can lock the pulling mechanism to prevent the pulling mechanism from rebounding due to hitting the limit part after rotating to the limit point at high speed.

[0022] c) The snap structure is unlocked by an unlocking sleeve, and other tools are not required to realize the rotation of the pulling mechanism. Description of the Drawings

[0031] The separable connector with multi - stage compensation and self - locking functions of the present invention will be further described in detail below with reference to the accompanying drawings, but the claimed scope of protection is not limited thereto.

[0032] As Figure 1 shown, the separable connector of this embodiment includes a two - stage length compensation structure and a self - locking structure, and the separable connector mainly consists of a separable socket 1, a separable plug 2, a rotating pin 3, a pulling mechanism 4, a cable 5, a tail accessory 6, an adapter plug 7, and an adapter socket 8.

[0033] The separation plug 2 is connected to the adapter plug 7 through a cable 5 to ensure normal signal transmission after docking. The separation plug 2 is connected to the support mechanism 4 through a rotating pin 3, wherein the first-level compensation is achieved by the up and down sliding of the sliding sleeve 10, and the second-level compensation is achieved by the sliding sleeve 10 pushing the positioning sleeve 12 to slide up and down. A first spring 11 is provided in the support mechanism 4, and the first spring 11 is fixed by the spindle structure on the nut 13 to prevent the first spring 11 from shaking in the nut 13, and realize the compensation function of the sliding sleeve 10 and the positioning sleeve 12.

[0034] Specifically, the support agency 4 is as follows Figure 2 and Figure 5 As shown, it is mainly composed of a bracket 9, a sliding sleeve 10, a first spring 11, a positioning sleeve 12, a nut 13, a rotating seat 14, a rotating shaft 15, a screw 16, a torsion spring a 17, an unlocking sleeve 18, a torsion spring b 19, a base 20, a buckle 22 and a second spring 23.

[0035] The support mechanism 4 rotates around the rotating shaft 15. Under the action of the compressed torsion spring a17 and the torsion spring b19, the support mechanism 4 is reset to the lowest limit position. The buckle 22 is pushed by the second spring 23 to extend into the circular through hole of the rotating seat 14 to lock the rotating seat 14 to prevent the support mechanism 4 from rebounding.

[0036] like Figure 1 The unlocking sleeve 18 is connected to the rotating shaft 15 through the screw 16. The unlocking sleeve 18 is pressed down, and the buckle 22 withdraws from the circular through hole of the rotating seat 14 to achieve unlocking, and the pulling mechanism 4 can rotate around the rotating shaft 15 again.

[0037] The separation plug 2 is connected to the adapter plug 7 via a cable 5 , and the tail of the adapter plug 7 is connected to the tail accessory 6 ; the support mechanism 4 is connected to the separation plug 2 via a rotating pin 3 , and is connected to the tail accessory 6 via a rotating seat 14 .

[0038] The separation socket 1 and the transfer socket 8 are fixed ends, and are fixed on the installation panel when in use. The separation plug 2 is directly plugged and locked with the separation socket 1, and the transfer plug 7 is threadedly connected and locked with the transfer socket 8.

[0039] The bracket 9 and the sliding sleeve 10 are fixed together by riveting, wherein the upper and lower error compensation is realized by the sliding sleeve 10 compressing the spring 11 to realize the primary compensation, and the sliding sleeve 10 compresses the spring 11 again and pushes the positioning sleeve 12 to move downward to realize the secondary compensation.

[0040] Figure 4In this state, when the separation socket 1 and the separation plug 2 need to be connected, the pulling mechanism 4 rotates around the rotating shaft 15, the torsion spring a17 and the torsion spring b19 are compressed to store energy, and the pulling mechanism 4 rotates a certain angle and contacts the base 20 and is limited, that is, the pulling mechanism 4 moves to the limit point and cannot continue to rotate, and then the separation socket 1 and the separation plug 2 are connected through multi-stage compensation.

[0041] Figure 3 In the state, when the separation socket 1 and the separation plug 2 need to be separated, the moving body moves to the right with the separation socket 1 and the separation plug 2. Due to the restriction of the pulling mechanism 4, the separation plug 2 can only move in a circle with the rotating shaft 15 as the rotating axis, so that it is gradually pulled away from the separation socket 1 during the movement. After separation, the separation plug 2 obtains the initial speed and acceleration, and the torsion spring a17 and the torsion spring 19b release the compression elastic force. Under the action of the compression elastic force, the separation plug 2 quickly leaves the separation interface under the drive of the pulling mechanism 4, rotates to the lowest point, and returns to Figure 4 In this state, the buckle 22 extends into the circular through hole of the rotating seat 14 under the thrust of the second spring 23, locks the pulling mechanism 4, and restricts it from continuing to rotate or rebounding to realize the self-locking function of the connector.
