Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the utility model to those skilled in the art.

In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.

Referring to fig. 1 and 2, a press-fit connector is provided according to an embodiment of the present utility model, which includes a male and a female end 200 that are matched.

Specifically, the male has at least one male pin 110, and the male pin 110 may be made of a conductive material, such as copper. The female end 200 has a jack adapted to at least one male pin 110, i.e., one male pin 110 corresponds to one jack. Each jack is provided with a conductive component 210, the conductive component 210 is electrically connected with the cable, and the conductive component 210 can move along the radial direction of the jack when the male pin 110 is inserted into the bottom of the jack, so that the conductive component 210 is in contact with the male pin 110 to form electrical connection. In an embodiment, the number of the male pins 110 and the number of the jacks are two, so that connection of the positive electrode and the negative electrode can be satisfied or connection can be performed through the two male pins 110 and the jacks, and connection stability can be ensured.

Therefore, when the male pin 110 is initially inserted into the jack, the conductive component 210 does not move, so that the male pin 110 can be inserted in a large gap, resistance and friction are reduced, and the service life of the connector is prolonged, while when the male pin 110 is inserted into the bottom of the jack, the conductive component 210 can move along the radial direction of the jack to be in contact with the male pin 110 to form electrical connection, and the tightening pressure between the conductive component and the male pin is ensured, so that the male head and the female end 200 can be stably connected.

Referring to fig. 2 and 4, in an embodiment of the present utility model, the mounting base 220 further includes a cylindrical structure, such as a cylinder or a square cylinder, for example. The mounting base 220 is disposed in the jack and is disposed coaxially with the jack. The conductive assembly 210 includes at least one pair of mating crimping tabs 211 and a compression bar 212, wherein the crimping tabs 211 are disposed on a sidewall of the mounting base 220 and can reciprocate along a radial direction of the mounting base 220. Specifically, the sidewall of the mounting seat 220 may be provided with a through hole through which the pressure bonding pad 211 passes, and the pressure bonding pad 211 may protrude from the inner surface of the mounting seat 220 under the action of external force so as to contact with the outer surface of the male pin 110 to form an electrical connection.

The crimp piece 211 may have any shape, and may be matched with the male pin 110, for example, a semicircular shape, a bar shape, or the like. In an example, the pressing piece 211 may be plate-shaped, and the shape of the side surface of the pressing piece may be adapted to the outer surface of the male pin 110, so as to ensure the fit between the pressing piece 211 and the outer surface of the male pin 110, and ensure the contact area between the pressing piece 211 and the outer surface of the male pin 110. In addition, the crimp tab 211 may be made of a conductive material, such as copper, and electrically connected to the cable.

Referring to fig. 2 and 3, the pressure lever 212 includes a pressure connection portion 212-a and an abutting portion 212-B connected at an angle, the connection portion of the pressure connection portion 212-a and the abutting portion 212-B is hinged on a side wall of the mounting seat 220, the abutting portion 212-B is located at the bottom of the mounting seat 220, the pressure connection portion 212-a is located at a side of the pressure connection piece 211 away from a central axis of the jack, and an included angle between the pressure connection portion and the abutting portion is opened towards the center of the jack. Thus, when the male pin 110 is not inserted to the bottom of the insertion hole, the crimp 212-a does not give pressure to the crimp piece 211, so that the male pin 110 can be inserted with a large clearance, reducing resistance and friction. When the male pin 110 is inserted into the bottom of the insertion hole, the male pin 110 contacts the abutting portion 212-B, and the press-connection portion 212-a can move towards the central axis of the insertion hole under the driving of the abutting portion 212-B to contact the press-connection piece 211, so that the press-connection piece 211 contacts the outer surface of the male pin 110 to form an electrical connection, and the attaching force between the press-connection piece 211 and the outer surface of the male pin 110 is ensured, so that the male head and the female end 200 can be stably connected.

It should be noted that, the compression bar 212 may have other shapes, so long as the movable compression tab 211 is moved toward the male pin 110 when the male pin 110 is inserted.

In one embodiment of the present utility model, the conductive component 210 further includes at least one elastic member (not shown), and two ends of the elastic member are respectively abutted against the crimping portion 212-a and the inner sidewall of the socket. Therefore, the elastic member can provide relatively constant elastic force to the compression bar 212 without being too rigid, so that the contact surface of the compression joint piece 211 and the male pin 110 can be attached by itself according to different angles, and the current carrying capacity of surface contact is fully obtained.

In another example, the number of the elastic members is two, and besides being disposed between the pressing portion 212-a and the inner sidewall of the insertion hole, two ends of the other elastic member may be abutted between the abutting portion 212-B and the bottom of the insertion hole, and the elastic members are disposed corresponding to the hinge positions of the pressing rod 212, so that the two elastic members may cooperate with each other to provide a relatively constant elastic force to the pressing rod 212, so as to ensure the contact quality between the pressing tab 211 and the male pin 110. In one example, the elastic member may be a counter-top wave spring.

In one embodiment of the present utility model, the conductive component 210 includes two pairs of matched crimping pieces 211 and a pressing rod 212, and the two pairs of crimping pieces 211 and the pressing rod 212 are respectively disposed at two sides in the jack, so that the two crimping pieces 211 can better attach to the male pin 110, and further ensure the stability of the connection between the male head and the female end 200. Meanwhile, the two pairs of crimping pieces 211 and the compression bar 212 are symmetrically arranged, so that the deviation of the male head can be prevented, and the occurrence of the conditions of virtual connection or unconnected state and the like caused by the deviation of the male head can be avoided.

It should be noted that, in other embodiments, the conductive component 210 may also include more than two pairs of press-fit tabs 211 and press-fit rods 212 to further ensure the stability of the connection between the male and female terminals 200, which is not limited in particular.

In one embodiment, the crimping piece 211 is electrically connected to the cable at the rear end through the flexible cable, so that the crimping piece 211 at the front end can be ensured to be freely movable within an allowable range, and any error of mounting precision does not have systematic influence on the conductive connection of the crimping piece 211. Since the press-contact pieces 211 are independently suspended in the through holes of the mounting seat 220 without pressure, the press-contact pressure is raised instantaneously by the press-contact before the final press-contact action is performed, and the press-contact pieces 211 can be quickly attached to the outer surface of the male pin 110 without friction during insertion, the influence of abrasion on the shape and service life of the electrical conductor (such as the male pin 110 or the press-contact pieces 211) can be greatly reduced.

In one embodiment, the surface of the crimp 212-a that contacts the crimp 211 is a cambered surface so that friction loss between the crimp 212-a and the crimp 211 can be reduced. And when the crimping part 212-a extrudes the crimping piece 211, the cambered surface can act on the centroid of the crimping piece 211, so that the crimping piece 211 can integrally move towards the male pin 110, and the contact area of the crimping piece 211 and the male pin is ensured.

In an embodiment, the head of the male pin 110 and the inlet of the jack are provided with guiding surfaces, so that the guiding function can be achieved when the male pin 110 is inserted into the jack, the insertion of the male pin 110 is facilitated, friction between the male pin 110 and the inlet of the jack can be reduced, and the service lives of the male pin 110 and the female end 200 are prolonged.
