Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

It should be noted that the terms "disposed" and "connected" should be interpreted broadly, and may be, for example, directly disposed or connected, or indirectly disposed or connected through intervening elements or intervening structures.

In addition, in the embodiments of the present invention, if there are terms of orientation or positional relationship indicated by "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., it is based on the orientation or positional relationship shown in the drawings or the conventional placement state or use state, and it is only for convenience of description and simplification of the description, but does not indicate or imply that the structures, features, devices or elements referred to must have a specific orientation or positional relationship, nor must be constructed and operated in a specific orientation, and therefore, should not be construed as limiting the present invention. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

The various features and embodiments described in the embodiments may be combined in any suitable manner, for example, different embodiments may be formed by combining different features/embodiments, and in order to avoid unnecessary repetition, various possible combinations of features/embodiments in the present invention will not be further described.

Referring to fig. 1 and 2, a male connector of a battery connector according to an embodiment of the present invention includes a plastic body 1 and a connection terminal 20, the connection terminal 20 is connected to the plastic body 1, wherein a connection groove 12 is disposed on a front surface of the plastic body 1, and the connection groove 12 can be used for being connected to a female connector. The connecting terminal 20 includes a connecting portion 201 and an extending portion 202, and the connecting portion 201 is connected to the plastic body 1 and is used for contacting with a connecting terminal of a female connector to realize conduction between the male connector and the female connector. Referring to fig. 3, one end of the extending portion 202 is connected to the connecting portion 201, the other end of the extending portion 202 extends outward and protrudes out of the back surface of the plastic body 1, and the outward extending end of the extending portion 202 is used for welding the male connector to the terminal body. So, when welding the male connector, because the one end of extension 202 extends to the outside and makes the welding position of male connector can avoid the bottom of plastic body 1 (be the region between the back of plastic body 1 and the terminal body), molten tin cream flows into the bottom of plastic body 1 when effectively preventing to weld, avoids plastic body 1 to be heightened by the tin cream, leads to the slope of male connector, guarantees welding quality. Meanwhile, the extending portion 202 protrudes from the back surface of the plastic body 1, so that a certain gap is formed between the back surface of the plastic body 1 and the terminal body, even if solder paste carelessly enters the bottom of the plastic body 1 during welding, due to the existence of the gap, the solder paste cannot raise the male connector, and the male connector is further prevented from inclining. In the concrete application, on the terminal of all kinds of electrified ponds, all need use the battery connector, especially to on the less mobile terminal of size volume, for example, the cell-phone, panel computer etc., the inside integrated level of this kind of product is higher, the inner space is effective, battery connector among the prior art is when the welding, because the size of battery connector is less, be subject to the welding precision, the tin cream gets into the bottom of plastic body 1 easily, make a certain position of public connector by bed hedgehopping, and then lead to the slope to appear in the public connector, influence and female connector between be connected, the condition such as contact failure appears easily, influence the normal use of equipment.

Referring to fig. 2 and fig. 3, as an optional implementation manner in this embodiment, the connection portion 201 may be an "n" shaped structure, and one end of the extension portion 202 away from the connection portion 201 is bent and extended in a direction away from the back surface of the plastic body 1, so that the end protrudes from the back surface of the plastic body 1. Thus, the extending portion 202 can form a certain gap between the back surface of the plastic body 1 and the terminal body, thereby facilitating subsequent welding.

Referring to fig. 4, as an alternative embodiment of the present invention, the plastic body 1 includes two side portions 11 and two fixing portions 10, the side portions 11 are located at two sides of the connecting groove 12, the fixing portions 10 are located at two ends of the connecting groove 12, and the side portions 11 and the fixing portions 10 surround to form the connecting groove 12. The side portion 11 and the fixing portion 10 are provided with a mounting groove 13, the connecting portion 201 can extend into the mounting groove 13, and after the connecting portion 201 is connected to the mounting groove 13, the connecting portion 201 can be exposed out of the surfaces of the side portion 11 and the fixing portion 10 to facilitate connection with the female connector.

Specifically, the plastic body 1 may be rectangular, the fixing portions 10 may be located at two ends of the plastic body 1 in the length direction, and two ends of the side portion 11 are respectively connected to the two fixing portions 10, so as to form the connecting groove 12. In the concrete application, can adopt between plastic body 1 and the connecting terminal 20 to inlay injection moulding, can be earlier respectively with connecting terminal 20 stamping forming, plastic body 1 injection moulding, connect connecting terminal 20 on the mounting groove 13 of plastic body 1 afterwards, the rethread is moulded plastics and is filled the reinforcement with the space between connecting terminal 20 and the plastic body 1 to make connecting terminal 20 can firmly be connected on plastic body 1.

With reference to fig. 4, preferably, the height of the fixing portion 10 may be higher than that of the side portion 11, and the thickness of the fixing portion 10 may be greater than that of the side portion 11, and compared with the side portion 11, the fixing portion 10 has higher structural strength, and when being connected with the female connector, the fixing portion 10 located on the plastic body 1 directly contacts with the female connector, so as to prevent the side portion 11 from being damaged due to connection abrasion.

Referring to fig. 1 again, as an optional implementation manner in this embodiment, the edges of the front surfaces of the side portions 11, the edges of the front surfaces of the fixing portions 10, and the edges of the connecting portions 201 exposed out of the plastic body 1 are provided with rounded chamfers, and when the female connector is connected, the rounded chamfers can guide the connection and the matching of the two, so that the connection between the two is smoother, and the wear caused by the connection jam is prevented.

As an optional implementation manner in this embodiment, the connection terminals 20 are provided in plural, and the plural connection terminals 20 are divided into two groups, and the two groups of connection terminals 20 are symmetrically connected to two sides of the plastic body 1.
