Detailed Description

The technical solutions in the embodiments of the present application will be described clearly below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present disclosure.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one.

The socket and the connector provided in the embodiments of the present application are described in detail with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

As shown in fig. 1, the socket disclosed in the related art includes a first central PIN 710, an internal mesh 740, and a first insulator 750, wherein the first central PIN 710 and the internal mesh 740 are both metal conductive parts, and the first insulator 750 is a rubber core. As shown in fig. 4, the plug disclosed in the related art includes a second center PIN 810, a housing 820, and a second insulator 830, wherein the first center PIN 710 and the housing 820 are both metal conductive portions, and the second insulator 830 is disposed between the second center PIN 810 and the housing 820.

As shown in fig. 2, which is a schematic diagram of the plug and the socket in the related art, the first PIN 710 contacts the second PIN 810 to electrically connect the two PINs, and the outer shell 820 of the plug contacts the inner mesh 740 of the socket to electrically connect the two PINs. The electrical connection comprises positive connection and negative connection, wherein the contact between the first central PIN 710 and the second central PIN 810 is positive electrical connection, and the contact between the outer shell 820 of the plug and the inner mesh 740 of the socket is negative electrical connection. Therefore, in this case, although the plug and the socket can be electrically connected by fitting, it is not possible to recognize whether or not the plug and the socket are electrically connected.

To solve the above problem, as shown in fig. 3, another socket disclosed in the related art includes a first center PIN 710, a ground PIN 720, a detection PIN 730, an internal network 740, and a first insulator 750. Wherein, first center PIN needle 710, ground PIN needle 720 and detection PIN needle 730 are metal conductive part, and first center PIN needle 710 is located the jack of socket, and ground PIN needle 720 and detection PIN needle 730 all set up outside the casing of socket, and ground PIN needle 720 ground connection detects PIN needle 730 and is connected with external processing platform to can detect the level change that detects PIN needle 730 through external processing platform, finally feed back to the user.

Also, ground PIN 720 and test PIN 730 are electrically connected by wiring within the housing. Therefore, in the case that the plug is not inserted into the jack, the ground PIN 720 and the detection PIN 730 are in an electrically conductive state, and since the detection PIN 730 is grounded, the external processing platform detects that the detection PIN 730 is at a low level.

After the plug is inserted into the jack, the first central PIN needle 710 is in contact with the second central PIN needle 810 to achieve positive electrical connection, meanwhile, the shell of the plug is in contact with the internal network 740 of the socket to achieve negative electrical connection, the ground PIN needle 720 and the detection PIN needle 730 are disconnected and electrically connected, the detection PIN needle 730 is in a suspended state, the level of the detection PIN needle 730 is clamped at a high level by means of a pull-up resistor, and therefore in the state, the external processing platform detects that the detection PIN needle 730 is at the high level.

Thus, if the external processing platform detects that the PIN 730 changes from low level to high level, it indicates that the plug has been inserted into the jack and is electrically connected to the socket; if the detection level is continuously low, namely no change exists, the plug and the socket are not electrically connected. Therefore, it is possible to recognize whether the plug and the socket are electrically conducted according to the process of detecting the level change of the PIN 730.

However, neither of the two socket solutions disclosed in the related art can identify the inserted plug.

Referring to fig. 5-8, the present application discloses a socket for connecting a first plug 610 or a second plug 620, wherein the first plug 610 and the second plug 620 are of different kinds. The socket comprises a socket body 100 and a first conductive part 200, wherein the socket body 100 is provided with a jack, the first conductive part 200 is arranged in the jack, the first conductive part 200 is used for being electrically connected with a first plug 610 or a second plug 620, and the first conductive part 200 can be connected with an external processing platform so as to detect the electric signal change of the first conductive part 200 through the external processing platform.

Specifically, the external processing stage may detect the level of the first conductive part 200, i.e., the external processing stage may be a level detector. Under the condition that the first plug 610 or the second plug 620 is not inserted into the jack or is not electrically connected with the first conductive part 200, it is described that the first conductive part 200 is in a suspended state, and at this time, the external processing platform detects that the level of the first conductive part 200 is a low level; when the first conductive part 200 is electrically connected to the first plug 610 or the second plug 620, it is described that the first conductive part 200 is in an electrically conductive state, and the external processing platform detects that the level of the first conductive part 200 is a high level.

The external processing platform may also sense current at the first conductive portion 200, in which case the external processing platform may be an ammeter or other current sensing device. Similarly, when the first plug 610 or the second plug 620 is not inserted into the jack or is not electrically connected to the first conductive part 200, it is described that no current passes through the first conductive part 200, and the current of the first conductive part 200 detected at this time is zero; when the first conductive part 200 is electrically connected to the first plug 610 or the second plug 620, the detected current of the first conductive part 200 passes through, and the current value is greater than zero.

In this embodiment, the external processing platform is a device for detecting the level. Of course, the external processing platform may be other devices or apparatuses, and in short, the user may know the change of the electrical signal of the first conductive part 200 through the external processing platform.

In the technical solution of the present application, in the process of inserting the first plug 610 into the jack, the electrical connection state of the first conductive part 200 and the first plug 610 changes; in the process of inserting the second plug 620 into the jack, the first conductive part 200 is continuously electrically connected with the second plug 620, i.e. the electrical connection state between the first conductive part 200 and the second plug 620 is unchanged.

Specifically, in the process of inserting the first plug 610 into the jack, the first conductive part 200 may be electrically connected to the first plug 610 first, and then the first conductive part 200 is electrically disconnected from the first plug 610; the first conductive part 200 may be electrically disconnected from the first plug 610, and then the first conductive part 200 is electrically connected to the first plug 610. Of course, during the process of inserting the first plug 610 into the jack, the electrical connection state between the first conductive part 200 and the first plug 610 may be another variation process as long as it is different from the continuous electrical connection process between the second plug 620 and the first conductive part 200.

In the present embodiment, when the first plug 610 is not inserted into the jack, the first conductive part 200 is in a suspended state; when the first plug 610 is partially inserted into the jack, the first plug 610 is electrically connected to the first conductive part 200; when the first plug 610 is fully inserted into the jack, the first plug 610 is electrically disconnected from the first conductive part 200. That is, the level of the first conductive part 200 is changed to a low level-high level-low level by the external processing platform during the period from the first plug 610 is not inserted into the jack to the first plug 610 is inserted into the jack.

When the second plug 620 is not inserted into the jack, the first conductive part 200 is also in a suspended state; in the case where the second plug 620 is partially or fully inserted into the jack, the second plug 620 is electrically connected to the first conductive part 200. That is, the level of the first conductive part 200 is changed to the low level to the high level by the external processing platform during the period from the time when the second plug 620 is inserted into the jack to the time when the second plug is inserted into the jack.

With such an arrangement, whether the inserted plug is the first plug 610 or the second plug 620 can be determined according to the process of changing the electrical connection state of the first conductive part 200, thereby achieving the purpose of identification.

In an alternative embodiment, as shown in fig. 5-8, the socket includes the second conductive part 300, the second conductive part 300 is also disposed in the jack, and in case one of the first plug 610 and the second plug 620 is partially inserted into the jack, the first plug 610 or the second plug 620 is electrically disconnected from the second conductive part 300, i.e. the first plug 610 or the second plug 620 is not in contact with the second conductive part 300; in a case where all of the second plug 620 and the second plug 620 are inserted into the jack, the first plug 610 or the second plug 620 is electrically connected to the second conductive part 300, that is, the first plug 610 or the second plug 620 is in contact with the second conductive part 300. The relative position of the second conductive part 300 and the first conductive part 200 is not limited as long as the above process can be implemented.

With this arrangement, in addition to identifying the plug through the first conductive part 200, the socket can be electrically connected to the plug through the electrical connection between the second conductive part 300 and the plug, so that the socket can be normally put into use.

In this embodiment, the second conductive part 300 may also be externally connected to an external processing platform, and the external processing platform may detect the change of the electrical signal of the second conductive part 300. Alternatively, the external processing platform may be a device capable of detecting a level, such as a level detector, a device capable of detecting a current, such as an ammeter, or other equipment or apparatus, and in short, the user may know the change in the electrical signal of the second conductive part 300 through the external processing platform.

In this way, when the external processing platform for detecting the level is externally connected to the second conductive part 300, if the first plug 610 or the second plug 620 is electrically connected to the second conductive part 300, the level of the second conductive part 300 detected by the external processing platform is high; if the first plug 610 or the second plug 620 is electrically disconnected from the second conductive part 300, it indicates that the second conductive part 300 is in a floating state, and the level of the second conductive part 300 detected by the external processing platform is a low level.

Therefore, it is possible to determine whether or not the second conductive part 300 is electrically connected to the corresponding plug based on the level of the second conductive part 300 detected by the external processing platform, thereby realizing the insertion detection function.

In summary, in the technical solution of the present application, when the first plug 610 is partially inserted into the jack, the first plug 610 is electrically connected to the first conductive part 200; when the first plug 610 is fully inserted into the jack, the first plug 610 is electrically connected to the second conductive part 300. In a case where the second plug 620 is partially inserted into the jack, the second plug 620 is electrically connected to the first conductive part 200; when the second plug 620 is inserted into the jack, the second plug 620 is electrically connected to both the first conductive part 200 and the second conductive part 300.

Optionally, the first conductive part 200 is a cylindrical body, and the second conductive part 300 is a cylindrical body, wherein the cylindrical body and the cylindrical body are both disposed along an axis of the insertion hole, the cylindrical body is sleeved on an outer circumference of the cylindrical body, the cylindrical body extends from a first port of the cylindrical body, and the first port is a port of the cylindrical body close to an inlet end of the insertion hole. That is, in the process of inserting the first plug 610 or the second plug 620 into the jack, both the first plug 610 and the second plug 620 contact the first conductive part 200 to achieve electrical connection, and then contact the second conductive part 300 to achieve electrical connection.

In this embodiment, the first conductive part 200 and the second conductive part 300 are both located at the center of the insertion hole, but the first conductive part 200 and the second conductive part 300 may be disposed at other positions in the insertion hole.

Further, each of the first conductive part 200 and the second conductive part 300 may be a columnar body or a cylindrical body, and may be arranged in order along the axial direction of the insertion hole, and the first conductive part 200 may be positioned on the side of the second conductive part 300 close to the inlet end of the insertion hole. In this way, during insertion into the receptacle, the plug can be electrically connected to the first conductive part 200 in contact therewith and then electrically connected to the second conductive part 300 in contact therewith.

With such an arrangement, the first conductive part 200 is close to the inlet end of the jack relative to the second conductive part 300, so that the plug can contact the first conductive part 200 first and then contact the second conductive part 300 in the process of being inserted into the jack; in addition, the first conductive part 200 and the second conductive part 300, both being cylindrical or cylindrical, are provided with contact surfaces along the circumferential direction of the axis of the insertion hole, increasing the probability of contact with the plug and reducing the requirement for the insertion angle of the plug.

In an optional embodiment, the socket further comprises a connecting piece, the connecting piece is arranged between the cylindrical body and the cylindrical body, the connecting piece is connected with both the cylindrical body and the cylindrical body, and the connecting piece is made of an insulating material. Specifically, the connecting piece can be insulating glue which is adhered to the outer surface of the cylindrical body and the inner wall surface of the cylindrical body; the connecting piece can also be an insulating rubber core which is contacted with the outer surface of the cylindrical body and the inner wall surface of the cylindrical body.

Thus, the first conductive part 200 and the second conductive part 300 are separated by the insulated connector, so that the first conductive part 200 and the second conductive part 300 are prevented from being directly electrically connected to form a short circuit.

In this embodiment, the connector is an insulation rubber core, and the connector includes an insulation cylinder 400, an inner wall surface of the insulation cylinder 400 contacts with the cylindrical body, and an outer wall surface of the insulation cylinder 400 contacts with the cylindrical body. As shown in fig. 6 to 8, the connector further includes an insulating main body, the insulating main body and the insulating cylinder 400 are integrated, and the insulating main body is clamped on an inner wall surface of the insertion hole, so as to fix the insulating cylinder 400 between the cylindrical body and the cylindrical body, the first conductive portion 200 penetrates through the insulating cylinder 400 and the insulating main body along an axial direction of the insertion hole, and the second conductive portion 300 is sleeved on an outer periphery of the insulating cylinder 400.

With this arrangement, the insulating cylinder 400 arranged in the circumferential direction separates the cylindrical body from the cylindrical body to a greater extent, thereby further avoiding the risk of short circuit caused by contact between the first conductive part 200 and the second conductive part 300.

In a further technical solution, as shown in fig. 6, the socket includes a third conductive portion 500, the third conductive portion 500 is disposed in the jack, the first plug 610 and the second plug 620 each include a fourth conductive portion 611, and in a case where the first plug 610 or the second plug 620 is inserted into the jack, the third conductive portion 500 is in contact with and electrically connected to the fourth conductive portion 611.

In this embodiment, the third conductive part 500 may be a metal conductive part provided on the inner wall surface of the insertion hole, and the third conductive part 500 is in a mesh shape, and the third conductive part 500 protrudes from the inner wall surface of the insertion hole; the fourth conductive portion 611 is a metal case, and the third conductive portion 500 is in contact with an outer surface of the metal case when the first plug 610 or the second plug 620 is inserted into the jack. Of course, in other embodiments, the third conductive part 500 may be disposed at other positions in the jack, or may be a metal conductive part with other structures, and may be in contact with the first plug 610 or the second plug 620 to achieve electrical connection.

With such an arrangement, in the process of inserting the first plug 610 or the second plug 620 into the jack, the raised meshed metal conductive part is easily contacted with the metal shell, so that electrical connection is realized.

In the present embodiment, first conductive part 200 corresponds to sense PIN 730 in the related art, second conductive part 300 corresponds to first center PIN 710 in the related art, third conductive part 500 corresponds to inner mesh 740 in the related art, and fourth conductive part 611 corresponds to housing 820 in the related art, so that the electrical connection between first conductive part 200 and second center PIN 810 of the plug is a positive electrical connection, and the electrical connection between third conductive part 500 and fourth conductive part 611 is a negative electrical connection.

Thus, while first conductive portion 200 is electrically connected to second center PIN 810 of the plug, third conductive portion 500 is electrically connected to fourth conductive portion 611, enabling electrical connection of the jack to first plug 610 or second plug 620.

In an alternative embodiment, the third conductive portion 500 may be a metal elastic member. The metal elastic element can be a spring or other metal elastic elements. In a case where the first pin 610 is inserted into the jack, the metal elastic member is compressed between the inner wall surface of the jack and the first pin 610; likewise, in the case where the second header 620 is inserted into the socket, the metal elastic member is compressed between the inner wall surface of the socket and the second header 620.

With such an arrangement, the first plug 610 or the second plug 620 is abutted against the second conductive part 300 by the elastic acting force of the metal elastic part, so that the first plug 610 or the second plug 620 is fixed relative to the socket, and the first plug 610 or the second plug 620 is prevented from being separated from the jack in the using process.

In the technical solution of the present application, as shown in fig. 7 and fig. 8, each of the first plug 610 and the second plug 620 includes two insertion portions 612, an insertion gap 613 is formed between the two insertion portions 612, and the insertion gap 613 is used for the first conductive part 200 and the second conductive part 300 to extend into. The two insertion portions 612 may be an integral structure, the two insertion portions 612 are both located in the metal housing, and a protrusion is disposed on a side of the two insertion portions 612 facing each other, and contacts with the first conductive portion 200 or the second conductive portion 300 through the protrusion.

Specifically, in a case where the first plug 610 is partially inserted into the jack, the first conductive part 200 extends into the insertion gap 613, and both the insertion parts 612 are in contact with the first conductive part 200; as shown in fig. 7, when the first plug 610 is fully inserted into the jack, the first conductive part 200 and the second conductive part 300 both extend into the plug gap 613, and both plug parts 612 contact the second conductive part 300.

In the present embodiment, the two insertion parts 612 of the first plug 610 have the same size along the axial direction of the jack, and the two insertion parts 612 have the same structure. Of course, in other embodiments, the size and structure of the two insertion portions 612 may be different, as long as the insertion process is implemented to contact the first conductive part 200 before the second conductive part 300.

Specifically, when the second plug 620 is partially inserted into the jack, one of the mating parts 612 contacts the first conductive part 200, and the other mating part 612 contacts neither the first conductive part 200 nor the second conductive part 300. As shown in fig. 8, when the second plug 620 is fully inserted into the jack, the first conductive part 200 extends into the plug gap 613, the plug portion 612, which was in contact with the first conductive part 200, moves to the position of the second conductive part 300 and contacts the second conductive part 300, and the plug portion 612, which was in a suspended state, contacts the first conductive part 200, that is, the two plug portions 612 contact the first conductive part 200 and the second conductive part 300 respectively to achieve electrical connection, and at this time, the first conductive part 200 and the second conductive part 300 are shorted.

In the present embodiment, the two insertion parts 612 of the second plug 620 have different sizes along the axial direction of the insertion hole, and the size of the first insertion part is smaller than that of the second insertion part. When the second plug 620 is inserted into the jack, the first mating part is the mating part 612 contacting the first conductive part 200, and the second mating part is the mating part 612 contacting the second conductive part 300.

In an alternative embodiment, first conductive portion 200 is an elastic conductive portion. Specifically, in order to facilitate the first conductive part 200 to extend into the insertion gap 613 and simultaneously achieve the contact between the first conductive part 200 and the insertion part 612, the distance between the two protrusions is usually smaller than the diameter of the cylindrical body, otherwise, the distance between the two protrusions is too large, and the protrusions are not easily contacted with the insertion part 612, so that the first conductive part 200 has an elastic property, and the first conductive part 200 can be elastically deformed to be squeezed between the two protrusions, thereby facilitating the extension into the insertion gap 613 and contacting with the protrusions of the insertion part 612.

Based on the socket of the present application, the embodiment of the present application further discloses a connector, the disclosed connector includes at least one of the first plug 610 and the second plug 620, and the socket of the above embodiment, and the first plug 610 and the second socket can be inserted into the jack of the socket respectively.

While the present embodiments have been described with reference to the accompanying drawings, it is to be understood that the invention is not limited to the precise embodiments described above, which are meant to be illustrative and not restrictive, and that various changes may be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
