As mentioned in the background art, for agricultural unmanned equipment (e.g. unmanned aerial vehicle, unmanned aerial vehicle), the electric connector is an important component, for example, for unmanned aerial vehicle, the working environment is very bad, the battery and the machine body are two independent devices, the battery is pulled out from the machine body when needing to be charged, and is plugged back into the machine body after being charged, and the plug connection of the battery and the machine body needs to be by means of the electric connector.

In the prior art, the number of times of plugging and unplugging the electric connector between the battery and the machine body reaches more than one thousand times, and the number of times of plugging and unplugging is more because the electric connector has a plug-in stroke, and the terminals of the electric connector are worn, so that the overcurrent capacity of the electric connector is affected.

Meanwhile, due to the fact that grooves or holes exist in the connecting mode of plugging, impurities are easy to enter, butt joint of the connector of the battery of the electric connector and the machine body connector is affected, and due to the fact that strong vibration exists in the unmanned aerial vehicle working environment, mutual vibration exists between the battery and the machine body easily, and service life of the electric connector is affected.

In view of this, please refer to fig. 1-4, the electrical connector 1000 and the agricultural unmanned device provided in the embodiment of the present utility model can solve this problem, which will be described in detail below.

The embodiment of the utility model provides an agricultural unmanned equipment (not shown), which can be an unmanned vehicle, an unmanned plane and the like, can be applied to agricultural scenes, and can be provided with various operation equipment in the field of plant protection so as to realize operations of spraying medicaments, sowing seeds, powder and the like.

The unmanned vehicle can walk on land, can be applied to agro-farming industry, and is used for performing plant protection operation activities such as pesticide spraying or water sprinkling irrigation on crops.

The unmanned aerial vehicle can be applied to farming plant protection operation, can spray crops, and can spray liquids such as pesticides, water and the like.

Referring to fig. 1 and 2, in the present embodiment, the agricultural unmanned aerial vehicle may be understood as an agricultural unmanned aerial vehicle, the agricultural unmanned aerial vehicle includes a body 2000, a battery 3000, and an electrical connector 1000, the electrical connector 1000 includes a first electrical connection terminal 100 and a second electrical connection terminal 200, the first electrical connection terminal 100 is disposed on the battery 3000 of the agricultural unmanned aerial vehicle, the first electrical connection terminal 100 includes a first housing 110 and a first electrode 120, the first electrode 120 is connected with the first housing 110, the first electrode 120 has a first pressure contact surface 111, the second electrical connection terminal 200 is disposed on the body 2000 of the agricultural unmanned aerial vehicle, the second electrical connection terminal 200 includes a second housing 210 and a second electrode 220, the second electrode 220 is connected with the second housing 210, and the second electrode 220 has a second pressure contact surface 221.

It should be noted that, the first electrical connection terminal 100 and the second electrical connection terminal 200 may be understood as a battery 3000 terminal connector and a body 2000 terminal connector, that is, the first electrical connection terminal 100 and the battery 3000 are electrically connected, and the second electrical connection terminal 200 and the body 2000 are electrically connected.

When the battery 3000 needs to be mounted on the body 2000, that is, when the battery 3000 of the agricultural unmanned aerial vehicle is mounted on the body 2000 of the agricultural unmanned aerial vehicle, the first press-contact surface 111 is press-contacted with the second press-contact surface 221, and the first electric connection terminal 100 and the second electric connection terminal 200 are electrically connected by press-contact of the first press-contact surface 111 and the second press-contact surface 221, instead of the manner of electrically connecting by plugging in and out in the prior art.

At the same time, there is no mutual friction between the first and second crimp surfaces 111, 221, avoiding wear on the first and second electrodes 120, 220, i.e. reducing wear of the electrical connector 1000 itself, avoiding affecting the overcurrent capability of the electrical connector 1000.

Here, the first electrode 120 and the second electrode 220 may be understood as butt terminals for electrically connecting the battery 3000 and the body 2000, the first electrode 120 is fixed to the first case 110, and the first electrode 120 is also electrically connected with the circuit board 500.

Specifically, in order to facilitate crimping of the first crimp face 111 of the first electrode 120 and the second crimp face 221 of the second electrode 220, in the present embodiment, the first crimp face 111 protrudes from the first housing 110 and the second crimp face 221 protrudes from the second housing 210, so that the first crimp face 111 and the second crimp face 221 are in crimping contact.

Meanwhile, it is easily understood that the first and second crimp surfaces 111 and 221 are both planar, and the first crimp surface 111 is parallel to the second crimp surface 221 so that the first crimp surface 111 can be crimped on the second crimp surface 221 when the first housing 110 is depressed.

In this way, the first electrode 120 and the second electrode 220 are butted without passing through the grooves or holes, and impurities are prevented from affecting the butting of the connector of the battery 3000 of the electric connector 1000 and the connector of the body 2000.

Further, in order to avoid that the foreign matter stays on the first pressure contact surface 111 and the second pressure contact surface 221, a part of the wall surface of the first pressure contact surface 111 is convex, and a part of the wall surface of the second pressure contact surface 221 is convex, at this time, the foreign matter (for example, dust) more easily falls from the first pressure contact surface 111 or the second pressure contact surface 221.

Specifically, for example, a part of the wall surface of the second pressure-bonding face 221 is convex, that is, the middle of the second pressure-bonding face 221 is convex, and is higher than the entire periphery of the second pressure-bonding face 221, for example, a spherical face or an arc face, at which time, the impurity easily slides out of the second electrode 220 from the second pressure-bonding face 221.

Of course, in other embodiments, a portion of the wall surface of the first pressure contact surface 111 may be raised, or a portion of the wall surface of the second pressure contact surface 221 may be raised.

In order to ensure that the first press-contact surface 111 and the second press-contact surface 221 can be in close contact, the second electrical connection end 200 further includes an elastic member 290, the elastic member 290 is elastically abutted against the second housing 210 and the second electrode 220 at the same time, in this embodiment, the elastic member 290 is a spring, the elastic member 290 is sleeved on the outer side of the second electrode 220, and in the process of abutting the first electrical connection end 100 and the second electrical connection end 200, the elastic member 290 can be in a compressed state, so as to ensure that the first press-contact surface 111 and the second press-contact surface 221 can always maintain a sufficient contact pressure.

Specifically, the second electrode 220 is movably disposed on the second housing 210, the second housing 210 has an inner cavity 2121, the elastic member 290 is disposed in the inner cavity 2121, the second electrode 220 has a limiting portion 222, the limiting portion 222 is disposed in the inner cavity 2121, and the elastic member 290 elastically abuts against the second housing 210 and the limiting portion 222.

During the mating of the first electrical connection terminal 100 and the second electrical connection terminal 200, the second electrode 220 moves downward and compresses the elastic member 290.

Since the second electrode 220 is movably disposed on the second housing 210, a certain gap may exist, and in order to ensure the dustproof capability of the electrical connector 1000, the second electrical connection terminal 200 further includes a first dustproof member 250, and the first dustproof member 250 is simultaneously in sealing connection with the second electrode 220 and the second housing 210, and the first dustproof member 250 is made of silica gel, so as to better achieve the sealing dustproof effect.

In order to facilitate accurate crimping of the first and second crimp surfaces 111 and 221, the first housing 110 is provided with a positioning post 310, the second housing 210 is provided with a positioning groove 320, and the positioning post 310 may be adapted to the positioning groove 320, i.e. positioning between the first housing 110 and the second housing 210 is achieved.

Meanwhile, in order to secure the fastening connection of the first housing 110 and the second housing 210, the electrical connector 1000 further includes a locking mechanism 400, the locking mechanism 400 being provided at the first housing 110, the locking mechanism 400 being used to lock the first housing 110 and the second housing 210 from relative movement, or the locking mechanism 400 being used to unlock the first housing 110 and the second housing 210 so as to be separated from the first housing 110 and the second housing 210, so as to facilitate the removal of the battery 3000 from the body 2000.

In this embodiment, the locking mechanism 400 may be understood as a movable buckle, however, in other embodiments, the locking mechanism 400 may be an electromagnet, the first housing 110 and the second housing 210 may be detachably connected through the electromagnet, and in addition, the first housing 110 and the second housing 210 may be fastened through a screw or a bolt.

In order to suppress vibration of the body 2000 from being transmitted to the electrical connector 1000 and to improve the life of the electrical connector 1000, the second electrical connection terminal 200 further includes a damper housing 230 and a plurality of damper members 240, which may be understood as damper gels, for example, made of silicone rubber or rubber.

The second housing 210 is movably disposed in the damper housing 230, the plurality of damper members 240 are disposed in the damper housing 230, and the plurality of damper members 240 simultaneously connect the second housing 210 and the damper housing 230, it should be noted that the damper members 240 have a certain length, and herein the length of the damper members 240 may be understood as a length dimension of the damper members 240 in a direction in which the first electrode 120 approaches the second electrode 220.

Thus, the vibration damping member 240 can ensure a certain range of motion of the second housing 210 in a plurality of directions (X-axis, Y-axis, and Z-axis) in space, thereby improving the vibration damping capability.

In addition, since the shock absorbing member can be elastically deformed, the second housing 210 can be driven to approach the first housing 110, that is, the second electrode 220 approaches and contacts the first electrode 120, and even if the positioning post 310 and the positioning groove 320 are not aligned, the first press-contact surface 111 and the second press-contact surface 221 can still be ensured to be press-contacted, so that the electrical connection between the battery 3000 and the body 2000 is ensured, and meanwhile, the positioning post 310 is prevented from directly striking the second housing 210, and the electrical connector 1000 is prevented from being damaged.

Since the second housing 210 is movably disposed in the shock-absorbing shell 230, the second electrical connection terminal 200 further includes the second dust-proof member 260, and the second dust-proof member 260 is simultaneously and sealingly connected to the shock-absorbing shell 230 and the second housing 210, the second dust-proof member 260 may also be made of silica gel, so as to achieve better sealing and dust-proof effects.

In addition, for convenience, each power module 2200 on the main body 2000, such as a propeller power module, a spraying system power module, etc., please refer to fig. 3 in combination with fig. 2.

The second electrical connection terminal 200 further includes a shunt electrode 270 and a flexible connection wire 280, the shunt electrode 270 and the shock-absorbing housing 230 are fixedly connected, and the second electrode 220 is electrically connected to the shunt electrode 270 through the flexible connection wire 280.

The shunt electrode 270 is electrically connected to each of the power consumption modules 2200 through the power consumption module electrode 2100, specifically, the power consumption module electrode 2100 is an OT terminal through a conventional electrical connection line 2300 between the power consumption module 2200 and the power consumption module electrode 2100.

While the flexible connection wire 280 is used between the second electrode 220 and the shunt electrode 270, the flexible connection wire 280 employs a special flexible wire, such as a copper braid, to improve the vibration resistance of the electrical connector 1000, it is easy to understand that the conventional electrical connection wire 2300 is used, and the wire is hard, so that the deformation capability of the vibration damper 240 is not only affected, but also the wire may be broken or crushed due to vibration.

Referring to fig. 4, in some embodiments, the number of the second electrodes 220 of the electrical connector 1000 may be plural, and the plural second electrodes 220 are simultaneously electrically connected to one shunt electrode 270 through plural flexible connection wires 280. Thus, even if a part of the second electrodes 220 cannot normally contact the first electrodes 120, only one well-contacted second electrode 220 can ensure the overcurrent capability, and the more well-contacted second electrodes 220, the stronger the overcurrent capability.

In some embodiments, the plurality of first electrodes 120 may be respectively contacted with the plurality of second electrodes 220, or one first electrode 120 may be simultaneously contacted with the plurality of second electrodes 220, or the plurality of shunt electrodes 270 may be plural, for example, one shunt electrode 270 may be simultaneously electrically connected with three second electrodes 220.

Referring again to fig. 2, when the battery 3000 is to be assembled on the body 2000, the positioning posts 310 of the first electrical connection terminal 100 and the positioning grooves 320 of the second electrical connection terminal 200 are adapted, and the positioning grooves 320 act as guides until the first press-contact surface 111 of the first electrode 120 starts to contact the second press-contact surface 221 of the second electrode 220, the elastic member 290 outside the second electrode 220 starts to compress, and the second electrode 220 moves relative to the second housing 210.

Meanwhile, the first housing is continuously pressed down, the first housing and the second housing 210 start to contact, after the first press-contact surface 111 completely contacts the second press-contact surface 221 of the second electrode 220, the first housing and the second housing 210 are locked by the locking mechanism 400, where, since the elastic member 290 is in a compressed state, the first press-contact surface 111 and the second press-contact surface 221 can be ensured to be firmly contacted, and meanwhile, since the electric connector 1000 is provided with the vibration absorbing member 240 and the flexible connecting wire 280, vibration between the battery 3000 and the body 2000 is not easily transmitted to the first electrode 120 and the second electrode 220, so that mutual sliding friction between the first press-contact surface 111 and the second press-contact surface 221 is avoided, abrasion is reduced, and meanwhile, the condition of current instantaneous break is prevented.

The first electrical connection end 100 and the second electrical connection end 200 are electrically connected by crimping the first crimping surface 111 and the second crimping surface 221 instead of the electrical connection mode by plugging in and out in the prior art, meanwhile, no mutual friction force exists between the first crimping surface 111 and the second crimping surface 221, abrasion to the first electrode 120 and the second electrode 220 is avoided, namely, abrasion of the electrical connector 1000 is reduced, and overcurrent capacity of the electrical connector 1000 is prevented from being influenced.
