Detailed Description

In order to make the technical problems solved, the technical solutions adopted and the technical effects achieved by the present application more clear, the technical solutions of the embodiments of the present application are described in further detail below, and it is obvious that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

In the description of the present application, unless explicitly stated and limited otherwise, the terms "connected," "secured" and "fixed" are to be construed broadly, as for example, they may be fixedly connected, detachably connected, or integrated; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communicated with the inside of two elements or the interaction relationship of the two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

In this application, unless expressly stated or limited otherwise, a first feature "above" or "below" a second feature may include both the first and second features being in direct contact, and may also include the first and second features not being in direct contact but being in contact with each other by way of additional features therebetween. Moreover, a first feature being "above," "over" and "on" a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature is higher in level than the second feature. The first feature being "under", "below" and "beneath" the second feature includes the first feature being directly under and obliquely below the second feature, or simply means that the first feature is less level than the second feature.

In the unmanned vehicle scene, the charging process of the electric vehicle is often independently completed by the vehicle, and the scheme which is relatively commonly used in the industry at present is that the male contact and the female contact exposed in a large area are closely contacted, and the scheme can be well balanced in terms of the butting precision, the electric control difficulty and the cost. In the existing charging plug-in structure, in order to ensure that the contact pieces on the male plug and the female socket can be fully contacted, the contact pieces are generally arranged to be elastic pieces, and certain interference exists between the contact pieces at the installation position, so that the contact pieces can be tightly contacted by utilizing the elastic force of the contact pieces after the plug-in. Therefore, in the plugging process, relative friction exists between the contact pieces of the male plug and the contact pieces of the female socket all the time, so that the abrasion of the contact pieces is accelerated to a certain extent.

In order to solve the above technical problems, as shown in fig. 1-11, the present embodiment provides a socket 100, which can be used for plug connection with a plug 200, and includes a socket contact 2 and an ejection mechanism 3, wherein:

the socket contact 2 is used for contacting and energizing with the side part of the plug 200; specifically, referring to fig. 6, the plug 200 includes a plugging guide post 201 and a plug contact 202 disposed on a peripheral portion of the plugging guide post 201, and when plugging, the plugging guide post 201 extends to an inner side of the socket contact 2, and the plug contact 202 contacts the socket contact 2, so as to achieve the butt joint of the socket 100 and the plug 200.

The ejection mechanism 3 can push the socket contact 2 away from the position of contact with the plug 200; and can cooperate with the plug 200, the ejector mechanism 3 is pushed to move by the plug 200, so that the ejector mechanism 3 drives the socket contact 2 to enter a position contacting with the plug 200.

Specifically, the socket contact 2 is in contact with the plug contact 202 at the side of the plugging guide post 201 to realize conduction, the direction of the plug 200 when plugged is taken as the axial direction, and in the process that the plug 200 is not plugged or plugged, the ejection mechanism 3 pushes the socket contact 2 away in the radial direction, so that friction between the plug contact 202 and the socket contact 2 can not occur in the plugging process; after the plug 200 is plugged in place, i.e. the plug contact 202 is opposite to the socket contact 2, the plug 200 can be contacted and push the ejection mechanism 3, and the ejection mechanism 3 drives the socket contact 2 to be radially close to the plug contact 202, so that the socket 100 and the plug 200 are connected.

In summary, according to the structure of the socket 100 of the present embodiment, the ejector mechanism 3 capable of being matched with the insertion and extraction of the plug 200 is provided, and in a separated state, the ejector mechanism 3 can push the socket contacts 2 away from the position contacting the plug 200, so that the plug 200 will not contact the socket contacts 2 during the insertion and extraction process, and further the problem of friction and abrasion between the plug 200 and the socket contacts 2 during the insertion and extraction process is reduced or avoided; after the plug 200 is inserted in place, the ejection mechanism 3 can be pushed to move, so that the ejection mechanism 3 drives the socket contact 2 to contact the plug 200, and contact electrification between the socket 100 and the plug 200 is realized.

In one embodiment, the ejector mechanism 3 includes a linkage assembly 31 and a first reset member 32, where the first reset member 32 is configured to push the socket contacts 2 away from a position contacting the plug 200; the linkage assembly 31 may be matched with the plug 200, and the plug 200 with the front end crossing the socket contact 2 may push against the linkage assembly 31 to move, so that the linkage assembly 31 drives the socket contact 2 into a position contacting with the side of the plug 200.

In a specific application, the front end of the plug 200 may be directly matched with the linkage assembly 31, or an intermediate transmission member may be disposed in the socket 100, and the intermediate transmission member is pushed by the inserted plug 200 and then transmits the driving force to the linkage assembly 31. Since the plug contacts 202 are disposed at the side of the plugging guide posts 201, the front end of the plug 200 passes over the socket contacts 2, and then the plug 200 can be pushed against the linkage assembly 31, so that the socket contacts 2 can be kept away from the plug contacts 202 in most of the moving paths of the plug 100, and the socket contacts 2 and the plug contacts 202 are kept in a larger inserting range.

In particular, and in comparison with fig. 6-8, in this embodiment, referring to fig. 6, in the unplugged state, the receptacle contacts 2 are offset from contact with the header contacts 202; referring to fig. 7, after the plugging guide post 201 is inserted into the socket 100, until the front end of the plugging guide post 201 passes over the socket contact 2, the socket contact 2 is kept still, so that the socket contact 2 is not contacted with the plugging guide post 201 and the plug contact 202 all the time in the process, and friction and abrasion during the insertion process can be avoided; referring to fig. 8, after the front end of the plugging guide post 201 passes over the socket contact 2, the sealing cover 41 will push the linkage assembly 31 to move, and the linkage assembly 31 drives the socket contact 2 to enter a position contacting the plug contact 202, so that the socket contact 2 can contact the plug contact 202 to realize power-on. In contrast, during the process of pulling out the plug 200, the first reset member 32 gradually pushes the linkage assembly 31 to reset, when the front end of the plugging guide post 201 enters between the socket contacts 2, the linkage assembly 31 pushes the socket contacts 2 to be separated from the position contacting with the plug contacts 202, so that the plug contacts 202 have no interference friction between the socket contacts 2, and therefore, during the process of pulling out the plug 200, only a small distance from just pulling out is generated between the plug contacts 202 and the socket contacts 2, and no friction exists between the plug contacts 202 and the socket contacts 2 in the main process, so that the problem of mutual abrasion between the plug contacts 202 and the socket contacts 2 is avoided to a large extent.

Regarding the implementation of the first reset element 32, in an embodiment, the first reset element 32 is connected to the linkage assembly 31, and the direction in which the linkage assembly 31 moves when the plug 200 is inserted and pushed into the linkage assembly 31 is taken as a positive direction, and the first reset element 32 pushes the linkage assembly 31 to move in a reverse direction, so as to drive the socket contact 2 to be away from a position contacting with the side portion of the plug 200.

The first reset piece 32 is connected with the linkage assembly 31, and the structure of the linkage assembly 31 is utilized to push the socket contact 2 back to reset, so that the effect of fully utilizing the use function of the linkage assembly 31 is achieved, the setting of the first reset piece 32 can be facilitated, and the structure inside the socket 100 is simplified.

Preferably, the first restoring member 32 is a spring, which has the advantage of being simple in structure and low in cost.

In an embodiment, to provide support and protection, the socket 100 of this embodiment further includes a socket housing 1, a jack hole 11 is provided on one side of the socket housing 1, a jack channel 12 coaxial with the jack hole 11 is formed inside the socket housing 1, the socket contact 2 is disposed on a side portion of the jack channel 12 in the socket housing 1, and the ejector mechanism 3 pushes the socket contact 2 to enter or depart from a position contacting with the plug 200 by pushing the socket contact 2 to approach or depart from the jack channel 12.

Specifically, during the plugging process of the plug 200, the plugging guide post 201 axially moves in the plugging channel 12, when the socket contact 2 is far away from the plugging channel 12, the socket contact 2 will not contact the plug 200, and when the socket contact 2 enters the plugging channel 12, the socket contact 2 can contact the plug 200, i.e. the purpose that the socket contact 2 enters or is far away from the contact position with the plug 200 during the plugging process is achieved.

With respect to the implementation of the linkage assembly 31, in an embodiment, referring to fig. 1-8, the plug 200 pushes the linkage assembly 31 axially, so that the linkage assembly 31 drives the socket contacts 2 to move in the axial insertion direction and the radial inward direction at the same time, so as to achieve that the socket contacts 2 approach the jack channels 12.

That is, during the insertion process, the moving direction of the socket contact 2 gradually approaches the plugging guide post 201 radially, and simultaneously, can also move axially along with the insertion of the plug 200, and the process is a gradual process that gradually approaches, which is smoother than the sudden ejecting manner. Importantly, taking the direction shown in fig. 8 as an example, during the process of pulling out, the socket contact 2 moves leftwards, and also moves leftwards, and meanwhile, gradually moves away from the socket contact 201, so that friction between the socket contact 2 which can move leftwards and the socket contact 201 is smaller, that is, abrasion of the initial stage of pulling out the plug 200 can be greatly reduced.

Based on the above scheme, in an embodiment, the linkage assembly 31 includes a first slider 311 and a link member 312, where the first slider 311 is slidably mounted in the socket housing 1, one end of the link member 312 is connected to the first slider 311, and the other end of the link member 312 is connected to the socket contact 2, and the first slider 311 is pushed to move axially by the plug 200, so that the first slider 311 drives the link member 312 to swing, and then the link member 312 drives the socket contact 2 to move along the axial direction and the radial direction at the same time.

Specifically, in this embodiment, based on the axial sliding of the first slider 311, the connection rod 312 drives the socket contact 2 to move along the axial direction and the radial direction, taking the angle shown in fig. 6-8 as an example, the plug 200 is inserted into the socket 100 from left to right, after the plug guide post 201 pushes the first slider 311, the first slider 311 is continuously pushed to move to the right, and the first slider 311 drives the socket contact 2 to move towards the direction close to the plug guide post 201 and to the right through the connection rod 312, i.e., in this process, the movement of the socket contact 2 is a gradual process of following the movement of the plug guide post 201 to the right and gradually approaching.

In one embodiment, the link member 312 includes a first link 3121 and a second link 3122 that are hinged, wherein an end of the first link 3121 away from the second link 3122 is hinged to the first slider 311, and an end of the second link 3122 away from the first link 3121 is hinged to the socket contact 2.

The use of both ends combined by the first link 3121 and the second link 3122 makes the link transmission structure, which makes the pushing process of the socket contact 2 smoother and softer.

In an embodiment, one end of the first reset element 32 is fixed in the socket housing 1, and the other end is connected to the first slider 311, and the first slider 311 is pushed by the first reset element 32 to move towards the direction of pulling out the plug 200, so that the link element 312 pushes the socket contact 2 away from the jack channel 12.

In this structure, only the first restoring member 32 needs to be set to have a restoring force opposite to the insertion force of the plug 200, so that the setting of the first restoring member 32 can be facilitated. In the structure shown in fig. 3, two sides of the plugging channel 12 are respectively provided with a socket contact 2, a first slider 311 is disposed between the two socket contacts 2, and the two socket contacts 2 are simultaneously pushed to move by sliding of the first slider 311, so that only one side of the first slider 311 is provided with a first reset piece 32, and the two socket contacts 2 can be simultaneously pushed to be far away from the plugging channel 12.

In an embodiment, the socket contact 2 is hinged with a first swing rod 23 and a second swing rod 24 that are parallel to each other, and one ends of the first swing rod 23 and the second swing rod 24, which are far away from the socket contact 2, are both rotatably connected in the socket housing 1, so that the socket contact 2 is always kept parallel to the axial direction in the process of driving the socket contact 2 to move by the link member 312.

Specifically, the first supporting points and the second supporting points for supporting the first swing rod 23 and the second swing rod 24 are arranged in the socket shell 1 at intervals along the axial direction, so that a parallelogram structure is formed among the socket contact 2, the first swing rod 23, the area between the first supporting points and the second supporting points, and the second swing rod 24, and therefore, in the process that the connecting rod piece 312 drives the socket contact 2 to move, the socket contact 2 is always parallel to the axial direction, namely, the overall contact or separation between the socket contact 2 and the plug 200 is completed instantly, and the stability of the contact process of the socket contact 2 and the plug 200 can be ensured.

Optionally, a set of first swing rods 23 and second swing rods 24 are respectively arranged on two opposite sides of the socket contact 2, so as to improve the stability of the movement of the socket contact 2.

In another embodiment, referring to fig. 9-11, the linkage assembly 31 includes an ejector spring 314 and a second slider 313, the second slider 313 is slidably mounted in the socket housing 1, and the socket contacts 2 are limited by the second slider 313, so that the socket contacts 2 are far away from the plugging channels 12; one end of the ejection spring 314 is fixed in the socket housing 1, the other end is connected with the socket contact 2, and the ejection spring 314 can push the socket contact 2 to approach the plugging channel 12; the second slider 313 is pushed to move axially by the plug 200, so that the second slider 313 abuts against or is separated from the socket contact 2, so that the socket contact 2 moves along the radial direction, and the socket contact 2 is further moved close to or away from the plugging channel 12.

Compared with the connecting rod type structure, the linkage assembly 31 of the structure has the advantages of simple structure and low cost.

In this way, the ejection of the socket contact 2 is achieved by the ejection springs 314, i.e. when the inner side of the socket contact 2 is out of limit, the ejection springs 314 eject the socket contact 2 so that the socket contact 2 can contact the header contact 202. In this structure, the ejection process of the socket contact 2 is a snap process, and a large impact is easily generated between the socket contact 2 and the header contact 202. Moreover, during the pulling-out process, before the second slider 313 pushes the socket contact 2 open, the socket contact 2 is always kept in close contact with the header contact 202, and the friction therebetween is large.

In a further aspect, the linkage assembly 31 further includes a sliding pushing block slidably mounted in the socket housing 1, the sliding pushing block may axially slide in the plugging channel 12, a guide roller 411 is disposed on a side portion of the sliding pushing block, and the socket contact 2 is propped open by the guide roller 411, so that the second slider 313 can be pushed out to a position limiting the socket contact 2.

Specifically, referring to fig. 9, in the unplugged state, the slide push block abuts the receptacle contact 2 from the top side, and the second slider 313 abuts the receptacle contact 2 from the bottom side, so that the receptacle contact 2 is held in a position deviated from contact with the header contact 202; in the insertion process, after the sliding push block abuts against the second slider 313, the second slider 313 is pushed to move continuously until the second slider 313 and the sliding push block are completely separated from the limit of the socket contact 2, and the socket contact 2 can automatically pop up to contact the plug contact 202. Conversely, when the socket is pulled out, under the action of the second reset piece 42, the sliding push block is pushed upwards, and simultaneously the socket contact 2 is propped open by the sliding push block, and simultaneously under the action of the first reset piece 32, the second slider 313 is pushed to a position limiting the socket contact 2, so that the purpose of propping open the socket contact 2 is achieved.

Since the ejector spring 314 always gives the socket contact 2 an elastic force pressing against the slide block, the provision of the guide roller 411 at the side portion of the slide block can avoid sliding friction between the slide block and the socket contact 2. Moreover, based on the arrangement of the guide roller 411, the sliding push block can easily pass over the corners of the socket contacts 2 and enter between the socket contacts 2 when the plug 200 is pulled out.

In an embodiment, a sealing cover 41 and a second reset member 42 are further disposed in the socket housing 1, and the second reset member 42 can push the sealing cover 41 to tend to seal the jack hole 11, so as to seal the jack hole 11; the sealing cover 41 may be matched with the insertion end of the plug 200, and the plug 200 inserted into the socket housing 1 may automatically push the sealing cover 41 away from the jack 11, so as to open the jack 11.

Based on the arrangement of the sealing cover 41, under the condition of being separated from the plug 200, the sealing cover 41 can cover and seal the plug hole 11, namely, the socket shell 1 and the sealing cover 41 together enclose a sealing shell, the socket contact 2 in the sealing shell is isolated from the external environment, the problem that the socket contact 2 is damaged rapidly due to the fact that the socket contact 2 is fully contacted with the external air can be avoided, and the service life of the socket contact 2 is prolonged.

Importantly, the sealing cover 41 is opened by the insertion and pushing of the plug 200, and the sealing cover 41 can be automatically closed after the plug 200 is pulled out, so that the method can be applied to the field of automatic charging, and the sealing cover 41 can be automatically controlled based on the insertion and pulling of the plug 200 without manual intervention.

In one embodiment, the sealing cover 41 is slidably mounted in the socket housing 1, and the sealing cover 41 can move in the axial direction in the plugging channel 12; a supporting seat 44 opposite to the plugging hole 11 is arranged in the socket shell 1, one end of the second resetting piece 42 is fixed on the supporting seat 44, and the other end is connected with the sealing cover 41; the socket contact 2 is disposed in the area between the support base 44 and the plugging hole 11, so that the plug 200 located at the side of the plug 200 can contact with the plug 200 after the plug 200 pushes the sealing cover 41 to pass over the socket contact 2.

Specifically, since the header contacts 202 are disposed on the side portions of the mating posts 201, the header contacts 202 are only contacted by the header contacts 2 in the header housing 1 from the side portions of the mating posts 201 in the mated state. The receptacle contacts 2 are disposed on the sides of the mating channels 12 and are capable of contacting the inserted header contacts 202. On the basis, the sealing cover 41 moves axially in the plugging channel 12 and does not interfere with the socket contact 2, so that the fixed supporting seat 44 is arranged in the socket shell 1, the supporting seat 44 is arranged at a position opposite to the plugging hole 11, the second reset piece 42 arranged on the supporting seat 44 can provide forward support for the sealing cover 41, and the stability of the sealing cover 41 and the second reset piece 42 in the moving process of the sealing cover 41 is improved.
