Referring to fig. 1 to 15, the socket of the present invention includes a housing 100, an electrical connector 200, and an elastic member 300; the electric connector 200 comprises two clamping pieces 201, the elastic member 300 comprises two clamping arms 301, and the two clamping arms 301 are clamped outside the two clamping pieces 201 to provide clamping force for the two clamping pieces 201 to approach each other.

The two clamping arms 301 of the elastic element 300 are clamped and fixed on the outer sides of the two clamping pieces 201 of the electric connector 200, so that in the assembling process of the socket, the elastic element 300 can be fixed on the electric connector 200 in advance, then the electric connector 200 fixed with the elastic element 300 can be assembled in the socket shell 100, and the elastic element in the prior art is not fixed between the socket shell and the clamping pieces of the electric connector after the electric connector is assembled in the shell. In the prior art, the elastic part needs to be fixed between the clamping piece of the electric connecting piece and the side wall of the shell in assembly, the space is very narrow, the assembly is very inconvenient, and the time consumed by the elastic part is far longer than that consumed by other stations, so that the scheme of the invention can greatly save the labor cost and improve the production efficiency of the whole production line.

In the present invention, there are various specific embodiments of the elastic member 300, and in one specific embodiment, the clamping arm 301 includes a clamping portion 302 and a deformation portion 303, the clamping portion 302 abuts against the outer side of the clamping piece 201, and the deformation portion 303 is connected to one end of the clamping portion 302. The deformation part 303 comprises a first deformation rod 304, and the end of the first deformation rod 304 is connected with the clamping part 302; two first deformation rods 304 of one elastic member 300 are fixedly connected. The deformation portion 303 is used for providing an elastic restoring force for the clamping portion 302, so that the clamping portion 302 can provide an elastic force for the two clamping pieces 201 of the electrical connector 200 to approach each other, thereby obtaining a good electrical contact effect between the clamping pieces 201 and the plug pins, and maintaining a good clamping force for the plug pins after the socket is plugged and unplugged for a plurality of times.

The connection between the two first deformation rods 304 of one elastic member 300 may be directly fixed together or indirectly fixed.

In the direct fixed connection, two first deformation rods 304 of one elastic element 300 share one end, which is the end far from the clamping portion 302. The specific implementation manner of the common end portion may be implemented by adopting a connection manner such as welding, or the like to be fixed as a whole, or may be implemented by adopting a manner that the two first deformation rods 304 of one elastic member 300 are integrally arranged; in an integrated implementation manner, the two first deformation rods 304 of one elastic member 300 may be formed by bending a metal rod.

In the indirect fixed connection, the ends of the two first deformation rods 304 of one elastic member 300, which are far away from the clamping portion 302, are respectively connected to another structural component, and the positional relationship of the two first deformation rods 304 of one elastic member 300 is relatively fixed under the condition of not applying force or restoring to the unstressed state after applying force. That is, the relative fixation between the two first deformation bars 304 of one elastic member 300 is achieved by the common and other fixing members.

In this embodiment, the two first deformation rods 304 of one elastic member 300 provide elastic restoring force to the two clamping pieces 201 of one electrical connector 200 by the clamping portions 302. When one end of the two first deformation rods 304 of one elastic member 300 is connected to the clamping portion 302 and the other end is directly fixed together, the two first deformation rods 304 of one elastic member 300 form a V-shaped elastic arm or a U-shaped elastic arm. In this embodiment, if the two first deformation rods 304 of one elastic member 300 are flat, a V-shaped elastic arm is formed; if the ends of the two first deformation rods 304 of one elastic member 300 far from the clamping portion 302 are bent to be arc-shaped and close to each other, a U-shaped elastic arm can be formed. The "V" and "U" shapes referred to in the present invention are only schematic representations and are not limited to the standard "V" or "U" shapes.

When two first deformation rods 304 of one elastic member 300 are arranged as "V" or "U" resilient arms, the structure of the elastic member 300 itself is relatively simple, which facilitates the processing and forming of the elastic member 300.

In order to maintain good elastic recovery capability under the condition that the structure of the elastic element 300 can be prevented from blocking the insertion of the plug pin, the invention further provides that the included angle between the first deformation rod 304 and the insertion direction of the plug pin is between 0 and 80 degrees. When the included angle is 0 degree, that is, the first deformation rod 304 is parallel to the insertion direction of the pin; when the included angle is 90 degrees, namely the first deformation rod 304 is perpendicular to the insertion direction of the pin; this embodiment defines the included angle between 0 and 80 degrees. When this contained angle is greater than 80 degrees, the angle of deflection undersize (be less than 10 degrees) between deformation pole and the clamping part 302, the clamping-force homogeneity of clamping part 302 centre gripping in the clamping piece outside is relatively poor, be close to the atress of one side of first deformation pole 304 promptly and can be far away from the atress of one side of deformation pole far away, the condition that clamping part 302 can not laminate clamping piece 201 can appear even, unfavorable clamping part 302 provides good elastic restoring force for clamping piece 201, thereby be unfavorable for clamping piece 201 and the good contact of participating in.

The present invention also provides another embodiment, in which, in addition to the first deformation rod 304, the deformation part 303 of one of the elastic members 300 further comprises at least one second deformation rod 305, and the second deformation rod 305 is connected to an end of the first deformation rod 304. In this embodiment, the second deformation rod 305 and the first deformation rod 304 provide an elastic restoring force together.

In one embodiment of this embodiment, one of the elastic members 300 includes two second deformation bars 305, and ends of the two second deformation bars 305 are fixedly connected. The second deformation rod 305 extends towards the inner side of the two clips. In this embodiment, the specific form of fixedly connecting the ends of the two second deformation rods 305 of one elastic member 300 can be multiple, such as directly fixing the two second deformation rods 305 into a whole, or jointly fixing the two second deformation rods 305 of one elastic member 300 to another component, so that the ends of the two second deformation rods 305 of the one elastic member 300 are relatively fixed. Wherein, the direct fixation into a whole includes the integration by welding or the like and the two second deformation rods 305 are formed by an integral component; when directly fixed into a whole, the two second deformation rods 305 of one elastic member 300 form a V-shaped or U-shaped elastic arm.

In this embodiment, the second deformation rod 305 may be implemented in various ways, specifically, referring to fig. 8 to 15, the second deformation rod 305 may also be configured as a torsion spring or an elastic rod. The torsional spring is used as the deformation rod, so that the maximum elastic limit of the elastic piece 300 can be increased, the elastic piece 300 is prevented from generating plastic deformation in the plugging and unplugging process of the pin, and the service life of the elastic piece 300 is prolonged; the use of the elastic rod simplifies the structure of the elastic member 300 and facilitates the fixing of the elastic member 300 to the electrical connector 200. In this embodiment, whether one elastic member 300 is provided with one or two second deformation bars 305, it may be provided as a torsion spring or an elastic bar. In this embodiment, the sources of the elastic restoring force provided by the elastic member 300 include the bending deformation of the first deformation bar 304 and the torsion deformation of the second deformation bar 305.

Specifically, the third morph rod 306 may be configured as a straight line, an arc, a V-shape, or a U-shape.

The third deformation rod 306, besides having a certain elastic recovery function, also has a function of connecting and fixing the two second deformation rods 305. The source of the elastic restoring force of the third deforming rod 306 is the bending deformation of the third deforming rod.

In this embodiment, one of the elastic members 300 includes two clamping portions 302, two first deforming rods 304, two second deforming rods 305, and one third deforming rod 306. The two clamping arms 301 of one elastic member 300 each include a clamping portion 302, a first deformation rod 304, a second deformation rod 305 and a third deformation rod 306, and in this embodiment, the two clamping arms 301 share the third deformation rod 306.

The elastic member 300 may be formed by bending an elastic metal rod, and the whole elastic member 300 is a whole; or a plurality of metal rods can be welded or connected by adopting other connecting modes. In this embodiment, the first deforming rod 304, the second deforming rod 305 and the clamping portion 302 of one clamping arm 301 of one elastic member 300 are fixed, and the three are integrally arranged in a U shape; the two second deformation rods 305 and the third deformation rod 306 of one elastic member 300 are fixed, and the three are integrally arranged in a U shape. The structure of the elastic member 300 of the present embodiment can avoid the mutual interference with the socket housing 100 and the plug pins while providing the extra elastic restoring force for the clamping piece 201 of the electrical connector 200, and ensure that the clamping piece is not interfered by other factors and falls off when being clamped on the clamping piece 201, and can complete the function of providing the elastic restoring force with a smaller structural member, thereby avoiding the socket structure from being too complicated.

In order to further enhance the stability of the elastic member 300 clamped on the clamping pieces 201, the present invention further provides an embodiment, in this embodiment, any two of the clamping pieces 201 are drawn together inward in the direction from inside to outside, and the end portions of the clamping pieces 201 in the direction close to the socket are folded outward, a concave portion 202 is formed on the outer side surface of the clamping piece 201, and a guide portion 203 is formed on the inner side surface of the upper end of the clamping piece 201 to guide the pins of the plug to be inserted into the two clamping pieces 201; the clamping portion 302 clamps the concave portion 202 abutting against the clamping piece 201. The clamping portion 302 is provided as a clamping bar to match the recess 202 of the clamping piece 201.

By forming the concave portion 202 on the outer surface of the holding piece 201 so that the holding portion 302 is held in the concave portion 202, the elastic member 300 can be stably held and fixed to the holding piece 201, and the elastic member 300 can be prevented from being accidentally dropped.

In order to ensure that the elastic element 300 can be stably clamped and fixed on the clamping sheet 201 even if the socket is accidentally dropped or bumped, a further embodiment is further provided in the present embodiment, referring to fig. 3 to 5, in order to better embody the position relationship between the limiting portion 101 and the elastic element 300 and hide an electrical connector 200, in the present embodiment, a limiting portion 101 for limiting the elastic element 300 is disposed in the housing 100 to prevent the elastic element 300 from falling off inside the socket.

When the clamping lever is clamped in the concave portion 202 of the clamping piece 201, the clamping lever is limited and fixed in the inserting and extracting direction of the pin, and the elastic member 300 is limited in all directions by the arrangement of the limiting portion 101, so that the elastic member cannot fall off when the electric connector 200 is installed in the socket housing 100.

In the present invention, the connection between the parts of the elastic member 300 may be integrated, or may be performed by using other connection methods such as welding, bonding, screwing, and clamping between the parts with different functions, which is not limited in the present invention.
