Description

Technical Field

[0001] The utility model relates to the technical field of electric connectors, in particular to a detachable electric connector with a buffer. Background Art

[0002] Separable and detachable electrical connectors are mainly used in aerospace, space transportation and other occasions where automatic separation and detachment are required to provide electricity, gas, liquid, signal and energy for the model. In some special application scenarios, due to the flammable, explosive and highly toxic characteristics of the transmitted medium, there are certain safety hazards in manual operation. During manual operation, due to the weight of the cable and limited space, there may be difficulties in plugging and matching due to axis deviation when the plug and socket are connected. At the same time, when the plug and socket are automatically ejected, due to the elastic force of the separation mechanism, the cable plug and socket will be ejected at a certain initial speed, which may uncontrollably collide with the launcher and model equipment, resulting in adverse effects. Under the new situation, aerospace launch sites have put forward higher requirements for unmanned operation and automation level, so the demand for automatic docking technology of separated and detached electrical connectors is becoming more and more urgent. For the automatic docking technology of separated and detached electrical connectors, most of the current applications use robotic arms to clamp the separated electrical connectors for docking and separation operations, which have shortcomings such as hard contact damage to the electrical connector and low docking and separation accuracy. Utility Model Content

[0003] The utility model aims to provide a detachable electric connector with a buffer, which can effectively solve the problems of hard contact damage of the electric connector and low precision of docking and detaching of the existing detachable electric connector.

[0004] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0005] A buffered detachable electrical connector comprises a connector body, an operator connection seat, a transmission mechanism for driving the connector body to separate, and a drive system for controlling the transmission mechanism, and also comprises a buffer mechanism connected between the connector body and the operator connection seat;

[0006] The buffer mechanism includes a first buffer component, a second buffer component and an elastic component. One of the first buffer component and the second buffer component is fixedly connected to the operator connecting seat, and the other is fixedly connected to the connector body. The elastic component is located between the first buffer component and the second buffer component to play a buffering role when the connector body is separated or docked.

[0007] In the above-mentioned detachable electrical connector with buffer, the first buffer member has a limiting hole along its axis, one end of the second buffer member extends into the limiting hole, and the elastic member is located between the bottom end of the limiting hole and the second buffer member.

[0010] In the above-mentioned detachable electrical connector with buffer, the other end of the second buffer is fixed on a fixing seat, the connector body is also fixed on the fixing seat, and a fixing groove matching with the connector body is formed on the fixing seat.

[0011] In the above-mentioned buffered detachable electrical connector, the transmission mechanism is also fixed on the fixing seat.

[0012] In the above-mentioned buffered detachable electrical connector, the transmission mechanism includes a driving motor, a gear pair and a driving shaft, the driving motor is fixed on the mounting plate, the gear pair is also arranged on the mounting plate, the driving shaft is connected to the driven gear in the gear pair, and the mounting plate is fixed on the fixed seat.

[0013] In the above-mentioned buffered detachable electrical connector, the driving system includes an electrically connected regulator and a controller, the regulator is electrically connected to the transmission mechanism, and the regulator and the controller are both fixed on the operator connection seat.

[0014] Compared with the prior art, the advantages of the utility model are:

[0015] By adding a buffer mechanism, a buffering effect is played when the separated and detached electrical connectors are docked, and the smooth automatic docking and separation of the separated and detached electrical connectors are achieved, providing a stable, sensitive and precise buffer for the docking mechanism, which can avoid hard contact damage between the electrical connector plug and the socket, and can achieve the smooth automatic docking and separation of the separated and detached electrical connectors, providing a new solution for the automatic docking of the separated and detached electrical connectors. The buffer mechanism includes two buffer parts and an elastic part arranged between the two buffer parts. During docking and separation, the elastic part is used to absorb impact to form protection, so as to achieve smooth and smooth docking of the plug and the socket.

[0016] Furthermore, the first buffer has a limiting hole along its axis, one end of the second buffer extends into the limiting hole, and the elastic member is located between the bottom end of the limiting hole and the second buffer. The limiting hole is used to limit the movement of the second buffer, thereby improving the stability and movement accuracy of the second buffer relative to the first buffer.

[0017] Furthermore, a linear bearing is provided between the inner side wall of the limiting hole and the second buffer, so that the second buffer can run more smoothly relative to the first buffer and can better guide the second buffer to move in a straight line.

[0022] Furthermore, the drive system includes an electrically connected regulator and a controller, the regulator is electrically connected to the transmission mechanism, and the regulator and the controller are both fixed on the operator connection seat. The drive system is fixed on the operator connection seat, which reduces the weight that the buffer mechanism has to bear, and can reduce the vibration effect on the drive system when the electrical connector is disconnected or disconnected, so as to maintain the long-term stable operation of the drive system.

[0037] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] See also Figures 1 to 4 This is an embodiment of the utility model of a detachable and detachable electrical connector with buffer, which includes a connector body 100, an operator connection seat 200, a transmission mechanism 300 for driving the connector body 100 to separate, and a drive system 400 for controlling the transmission mechanism 300, and also includes a buffer mechanism 500 connected between the connector body 100 and the operator connection seat 200; the operator connection seat 200 is used to connect with the operating component to fix the relative position of the connector body 100, and the drive system 400 is used to receive instructions and control the movement of the transmission mechanism 300, and the transmission mechanism 300 is connected to the connector body 100 to control the separation of the connector body 100 and other actions. In this solution, a buffer mechanism 500 is added. When the connector body 100 is separated, the buffer mechanism 500 can be used to offset the elastic force received during separation under the action of the separation spring, reduce the movement amplitude of the connector body 100, and avoid hitting other parts. When the connector body 100 is docked, it can also play a buffering role to offset the impact force on the connector body 100 during partial insertion.

[0039] like Figure 2 As shown, the specific buffer mechanism 500 includes a first buffer member 510, a second buffer member 520 and an elastic member 530. The first buffer member 510 is fixedly connected to the operator connection seat 200, the second buffer member 520 is fixedly connected to the connector body 100, and the elastic member 530 is located between the first buffer member and the second buffer member 520. The elastic member 530 plays a buffering role. The elastic member 530 can be a spring, a spring sheet or an elastic rubber. Of course, the positions of the first buffer member 510 and the second buffer member 520 can also be interchanged, which will not affect the buffering effect.

[0040] In order to further control the movement trajectory of the connector body 100 during docking or separation, a limiting hole is opened on the first buffer 510, one end of the second buffer 520 extends into the limiting hole, and the elastic member 530 is also located in the limiting hole, and is located between the bottom end of the limiting hole and the second buffer 520, so that the second buffer 520 can only make repeated movements relative to the axis of the limiting hole, and the limiting hole can also limit the relative position of the elastic member 530. The first buffer 510 is rod-shaped, and the limiting hole is opened along the axis of the first buffer 510 and is a blind hole, so that the limiting hole can be ensured to have sufficient length to provide a certain movement stroke space for the second buffer 520, and the second buffer 520 can also adopt a rod-shaped structure, so that the sufficient length can penetrate into the limiting hole, ensuring that the second buffer 520 has sufficient contact area with the limiting hole to limit the movement trajectory of the second buffer 520 when the second buffer 520 moves relative to the limiting hole.

[0041] On the basis of the above scheme, a linear bearing 540 can be installed between the first buffer 510 and the second buffer 520 to reduce the friction when the second buffer 520 moves relative to the first buffer. Specifically, the linear bearing 540 can be fixedly connected to the first buffer 510, and the linear bearing 540 can be installed in the first buffer 510. The fixed connection between the linear bearing 540 and the first buffer 510 is achieved by setting a step and a clamping ring on the limiting hole in the first buffer 510, and the second buffer 520 passes through the linear bearing 540 and extends into the limiting hole. In addition to reducing the friction between the first buffer 510 and the second buffer 520, the linear bearing 540 can also bear a certain torque load, so that the buffer mechanism 500 is more stable, sensitive and smooth when working.

[0042] The number of first buffer members 510 and second buffer members 520 in the buffer mechanism 500 can be selected according to the load conditions. In this embodiment, four first buffer members 510 are used, and the four first buffer members 510 are arranged in parallel and distributed at the four corners of the rectangle to evenly distribute the load.

[0043] One end of the second buffer member 520 is inserted into the limiting hole of the first buffer member 510, and the other end of the second buffer member 520 is fixed on the fixing seat 600. The connector body 100 is also fixed on the fixing seat 600. The impact received by the connector body 100 can be better transmitted to the second buffer member 520 through the fixing seat 600. In addition, a fixing groove 610 that cooperates with the connector body 100 is opened on the fixing seat 600, which makes it more convenient to fix the connector body 100 and the fixing seat 600.

[0044] like Figure 3As shown, further, the transmission mechanism 300 is also fixed on the fixing seat 600. Specifically, the transmission mechanism 300 includes a driving motor 310, a gear pair 320 and a driving shaft 330. The driving motor 310 is fixed on the mounting plate 340. The gear pair 320 is rotatably connected to the mounting plate 340. The driving motor 310 drives the driving shaft 330 to rotate through the gear pair 320. The driving shaft 330 is responsible for driving the connector body 100 to separate. The mounting plate 340 is fixed on the fixing seat 600. The shape of the fixing seat 600 of this embodiment is determined according to the shape and size of the connector body 100, the transmission mechanism 300 and the buffer mechanism 500, and mainly plays a connecting and fixing role between the three.

[0045] like Figure 4 As shown, the drive system 400 includes an electrically connected regulator 410 and a controller 420. The controller 420 is electrically connected to the transmission mechanism 300 and is used to send an electrical signal to the transmission mechanism 300 and control the movement of the transmission mechanism 300. The regulator 410 and the controller 420 are both fixed on the operator connection seat 200 and do not need to move with the buffer mechanism 500, which also reduces the load of the buffer mechanism 500.

[0046] The detachable electrical connector adopting the above scheme integrates the connector body 100, the operator connection seat 200, the transmission mechanism 300, the drive system 400 and the buffer mechanism 500. The transmission mechanism 300 and the drive system 400 provide the connector body 100 with power for automatic plugging and separation. The buffer mechanism 500 plays a smooth role when the detachable electrical connector is docked, realizing smooth docking of the electrical connector, avoiding hard contact damage to the electrical connector, and realizing smooth rotation docking and separation of the detachable electrical connector, providing a new solution for the automatic docking of the detachable electrical connector. The buffer mechanism 500 includes an elastic member 530, a first buffer member 510 and a second buffer member 520, which can provide a smooth effect with high stability, high sensitivity and high precision, realizing a smooth and smooth docking of the plug and the socket.

[0047] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
