With such PIN needles 120 and housing 110 being integrally molded by injection molding, when adjustment of PIN needles 120 (e.g., changing the position, number, etc. of PIN needles 120) is required, a different mold needs to be newly prepared.

In order to solve the above problems, the present application provides a connector including a housing and a connection structure including a first connector and a second connector, wherein the first connector has a socket end, the second connector is disposed on an inner peripheral wall of the housing, and the second connector has a socket hole, and the first connector and the second connector are detachably connected through the socket end and the socket hole.

According to the connector disclosed by the application, the second connecting piece with the plug hole is arranged on the inner peripheral wall of the shell, and the first connecting piece can be detachably connected with the plug hole of the second connecting piece through the plug end of the first connecting piece, so that the first connecting piece in the connector can be adjusted without preparing different dies, and the connector has the advantages of high efficiency, low cost and the like.

In addition, the first connecting piece and the second connecting piece belong to cold connection in a mode of detachable connection through the plug end and the plug hole, and compared with hot connection modes such as injection molding connection, welding and the like, the cold connection has higher safety, higher connection efficiency, lower cost and better environmental protection performance.

In the following description, for a thorough understanding of the present utility model, detailed steps and structures will be presented in order to illustrate the technical solution presented by the present utility model. Preferred embodiments of the present utility model are described in detail below, however, the present utility model may have other embodiments in addition to these detailed descriptions.

A connector according to an embodiment of the present application is described below with reference to fig. 3 to 5. As shown in fig. 3 to 5, the connector includes a housing and a connection structure including a first connection member 220 and a second connection member 230, wherein the first connection member 220 has a socket end 221, the second connection member 230 is disposed on an inner peripheral wall of the housing, and the second connection member 230 has a socket hole 231, and the first connection member 220 and the second connection member 230 are detachably connected through the socket end 221 and the socket hole 231.

Taking the position adjustment of the first connector 220 in the connector as an example, the first connector 220 is inserted into the second connector 230 at the corresponding position on the housing, so that the connector with multiple pin positions can be provided.

Taking the number adjustment of the first connectors 220 in the connector as an example, connectors having a plurality of pin numbers can be provided by inserting the first connectors 220 into a corresponding number of the second connectors 230 on the housing, respectively.

Of course, the foregoing is merely an example of adjusting the position and the number of the first connecting members 220 in the connector, and the present application does not exclude that other properties of the first connecting members 220, such as the shape, the material, etc. of the first connecting members 220, may be adjusted, which is not limited thereto.

Based on this, the present application provides a connector that facilitates adjustment of the first connector 220. According to the connector of the application, the second connecting piece 230 with the inserting hole 231 is arranged on the inner peripheral wall of the shell, and the first connecting piece 220 can be detachably connected with the inserting hole 231 of the second connecting piece 230 through the inserting end 221 of the second connecting piece, so that the first connecting piece 220 in the connector can be adjusted without preparing different dies, and the connector has the advantages of high efficiency, low cost and the like.

In addition, it should be noted that, in the present application, the first connection member 220 and the second connection member 230 are detachably connected through the plugging end 221 and the plugging hole 231, and compared with the hot connection method such as injection molding connection and welding, the cold connection has higher safety, higher connection efficiency, lower cost and better environmental protection performance.

In one example, the second connection member 230 may be inserted into a cavity of a mold at the time of processing, and then the housing is injection molded by closing the mold such that the second connection member 230 and the housing are integrally molded by injection molding.

Compared to the manner of integrally molding the PIN and the housing by injection molding, the embodiment only integrally molds the second connector 230 and the housing by injection molding, and the first connector 220 can be inserted into the insertion hole 231 of the second connector 230 through the insertion end 221 or removed from the insertion hole 231 of the second connector 230, so that the connector capable of conveniently adjusting the first connector 220 can be provided by only one pair of dies.

In one example, the inner peripheral wall of the housing may include only one inner side wall, or may include a plurality of inner side walls connected in sequence, which is not limited.

Taking the case that the inner peripheral wall of the housing includes only one inner side wall, one or more second connectors 230 may be disposed on the inner side wall, and one or more second connectors 230 may be plugged with corresponding first connectors 220, where the positions, the number, and other properties of the first connectors 220 may be adjusted according to actual requirements.

Taking the case that the inner peripheral wall of the housing includes a plurality of inner side walls connected in sequence as an example, one or more second connectors 230 may be disposed on each inner side wall, and one or more second connectors 230 on each inner side wall may be plugged with a corresponding first connector 220 (without excluding the case that one or more second connectors 230 on a certain inner side wall are not plugged with the first connectors 220), where the position, number and other properties of the first connectors 220 may be adjusted according to actual requirements.

In one example, the mating end 221 and the mating hole 231 are interference connected after the first connector 220 is assembled with the second connector 230. Through interference fit, after the plugging end 221 of the first connector 220 is plugged into the plugging hole 231 of the second connector 230, the first connector 220 and the second connector 230 can be reliably and tightly matched and connected without additional fixing components.

Moreover, the interference connection between the first connector 220 and the second connector 230 may also have a better contact resistance, and may provide a stable electrical connection while also being able to withstand higher currents and voltages.

In one example, the socket end 221 includes an elastic portion that elastically deforms when the socket end 221 is fitted into the socket hole 231; after the plug end 221 and the plug hole 231 are assembled and connected, the plug end 221 is in interference connection with the plug hole 231 through the elastic portion.

In a specific assembly process, the plugging end 221 of the first connector 220 may be aligned with the plugging hole 231 of the second connector 230, and then a pressure is applied to the first connector 220 to press the plugging end 221 into the plugging hole 231, and in the press-in process, the elastic portion elastically deforms and provides a low contact resistance, so that the plugging end 221 and the plugging hole 231 can be reliably and tightly connected in a matching manner.

In addition, since the elastic portion has a certain elastic range, the elastic portion can be deformed to a certain extent when receiving an external stress, thereby releasing the stress.

In one example, the material of the elastic portion may be an elastic metal (such as spring steel or nickel-copper alloy), an elastic plastic, or the like, which is not limited.

In one example, as shown in fig. 4, an end of the first connector 220 away from the socket end 221 is an electrical connection end 222, and the first connector 220 may be electrically connected to an electronic component such as a circuit board through the electrical connection end 222.

In one example, the first connector 220 may be a press-fit terminal that makes an electrically conductive connection through press-fit contact. The press-fit contact means that the two metal contact surfaces are brought into close contact due to elastic deformation of the metal after being pressed, thereby achieving conductive connection. The connection mode has higher contact resistance and mechanical strength, and can be suitable for higher current and voltage application.

The press-fit terminal may include a root portion, two elastic portions, and a pin portion, wherein the elastic portions are in a circular arc shape, and the two elastic portions are disposed opposite to each other to form a fisheye hole. When the connector is mounted, the elastic part is easily elastically contracted by being pressed, so that the elastic part is perfectly matched with the insertion hole 231 on the second connector 230.

In one example, the press-fit terminal may preferably be a fish eye terminal. A fisheye terminal is a special type of press-fit terminal, and its contact portion has a shape similar to a fisheye, and is thus named. The fish-eye terminal has the advantages of larger contact area, smaller contact resistance, higher mechanical strength, suitability for application of higher current and voltage, convenience in assembly, reliability in connection, difficulty in relaxation and the like.

In one example, the first connector 220 may be a PIN needle.

Of course, the present application does not exclude that the first connector 220 may be other types of connectors for connectors other than press-fit terminals, PIN PINs.

In one example, the socket hole 231 includes a guide hole and a clamping hole connected to each other, and the aperture of the clamping hole is smaller than the aperture of the guide hole.

When the first connecting piece 220 and the second connecting piece 230 are assembled, the inserting end 221 of the first connecting piece 220 is pressed into the guide hole, the inserting end 221 can be pressed into the clamping hole only by small pressure under the guide action of the guide hole, and the clamping hole can apply clamping force to the inserting end 221, so that reliable and tight matching connection between the inserting end 221 and the clamping hole can be realized. Thus, a larger clamping force can be obtained with a smaller pressure.

In an example, the end of the second connection piece away from the jack 231 may be connected with a power module through a wire, where the type of the power module may be selected according to practical needs, for example, an IGBT (Insulated Gate Bipolar Transistor ) module, a MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) module, a SiC (Silicon Carbide) module, or the like, which is not limited.

According to another aspect of the application, an electronic device is also provided. The electronic device includes a connector.

The connector may be implemented as a connector in the above embodiments, and reference may be made to the above description, which is not repeated herein.

In one example, the electronic device further includes a circuit board electrically connected to the first connector.

The Circuit board may be, but not limited to, a flexible Circuit board (Flexible Printed Circuit, FPC), a rigid Circuit board (RIGID PRINTED Circuit, RPC), a Hybrid PCB, a thick film Circuit board (THICK FILM Circuit, TFC), a thin film Circuit board (Thin Film Circuit, TFC), or the like. The first connecting piece can be electrically connected with the circuit board through the electric connecting end of the first connecting piece.

For example, the circuit board may be provided with a conductive hole, and the electrical connection end of the first electrical connector may be inserted into the conductive hole, so that the circuit board and the first connector are electrically connected. Of course, the circuit board may have other structures to be connected to the electrical connection end of the first electrical connector, which is not limited.

In summary, according to the connector and the electronic device provided by the embodiments of the present application, the second connecting piece having the plugging hole is disposed on the inner peripheral wall of the housing, and the first connecting piece can be detachably connected with the plugging hole of the second connecting piece through the plugging end of the first connecting piece, so that different molds are not required to be prepared, and the first connecting piece in the connector can be adjusted, which has the advantages of high efficiency, low cost, and the like.

In addition, the first connecting piece and the second connecting piece belong to cold connection in a mode of detachable connection through the plug end and the plug hole, and compared with hot connection modes such as injection molding connection, welding and the like, the cold connection has higher safety, higher connection efficiency, lower cost and better environmental protection performance.
