As described above, the first fixing member 3 and the second fixing member 3' have the same structure, and as shown in fig. 12, for example, an embodiment of a male connector is used, one end of the second substrate 301 is provided with a second beam 303 forming an included angle with the second substrate 301, and one end of the second fixing slot 302 is exposed out of the second beam 303 to form an open section 3021; the other end of the second fixing socket 302 extends into the second beam 303 and penetrates the second beam 303 to form a semi-closed section 3022.
The second beam 303 is perpendicular to one end of the second substrate 301, and the second beam 303 may be integrally formed with the second substrate 301.
In the embodiment shown in fig. 12, the second fixing slots 302 are arranged at equal intervals, the length of the open section 3021 is greater than that of the semi-closed section 3022, and the bottoms of the open section 3021 and the semi-closed section 3022 are a coherent whole on the second substrate 301. The open section 3021 is mainly used for connecting and protecting the subsequent wiring terminal 2 and the cable, and is convenient for the operation of the subsequent preparation process; the semi-closed section 3022 is used for fixing and positioning the male connection terminal 2 'and protecting the male connection terminal 2' during the process, so as to prevent the terminal from deforming.
In other embodiments, the second beam 303 may not be perpendicular to an end of the second substrate 301, for example, an acute angle or an obtuse angle may be formed between the second beam 303 and the second substrate 301.
In a preferred embodiment, as shown in fig. 13, the second fixing slot 302 may have a longitudinal cross-sectional shape of a semi-closed segment 3022 with a shape of a Chinese character kou. The shape of the slot is a similar shape, that is, a shape formed by combining two sides and upper and lower sides, wherein the specific arrangement of the included angles between the two sides and the lower side is not particularly required, and can be determined according to the design requirement of the connecting terminal 2.
Preferably, as shown in fig. 14, in a preferred embodiment, the longitudinal section of the semi-enclosed section 3022 may be concave, specifically, in order to better fix the inserted male terminal 2', a bump is disposed above the inserted male terminal 2' in the fixing slot of the semi-enclosed section 3022, and the end of the bump can assist in positioning the upper and lower positions of the male terminal 2', so as to better protect the terminal, and further facilitate the operation of the subsequent process and improve the yield.
Further, one end of the bump is fixed to the second beam 303, or directly extends from the second beam 303, and may be integrally formed with the second beam 303, and the other end of the bump contacts the male terminal 2' inserted into the second fixing slot 302, so that the longitudinal section of the fixing slot forms a "concave" shape.
In a part of the preferred embodiments of the present invention, the upper, lower, left and right positions of the male connection terminal 2 'may be positioned in an auxiliary manner by simultaneously providing the guide mechanism and the protruding blocks provided in the semi-closed section 3022, so that the male connection terminal 2' may be positioned very accurately during the installation and preparation process, and may not shake, thereby greatly helping the quality and final yield of the final product, especially in the automatic production.
In some embodiments of the present invention, the longitudinal section of the open section 3021 of the second fixing socket 302 is U-shaped. Specifically, since the upper portion of the open section 3021 has no second beam 303, the u-shape, i.e., the bottom, is a base, and the left and right sides are sides of the second fixing insertion groove 302, which may be in the form of two side shields. The U-shape is a generally similar shape, that is, it is formed by combining two sides and a bottom, wherein there is no specific requirement for a specific arrangement angle between the two sides and the bottom, and the like, and the U-shape can be determined according to the design requirement of the second connection terminal 2'.
The male connection terminal 2 'is inserted into the second fixing slot 302 via the semi-closed section 3022 and reaches the open section 3021, the area where the male connection terminal 2' is inserted into the open section 3021 is a second connection area 202 where the male connection terminal 2 'is connected to the second core wire 5' of the second cable, as shown in fig. 4, the second connection area 202 may be a welding area or a crimping area, and the specific process may be selected and determined according to the actual situation. Of course, in other embodiments, the male terminal 2' may also be the insertion of the open section 3021 of the second fixing socket 302 into the semi-closed section 3022, which has no essential effect on the implementation of the present invention.
The second carrier 4' has a receiving space formed by the second partition 401 corresponding to the position of the second fixing slot 302, so that the male connection terminal 2' is connected to the second core wire 5'. Meanwhile, the carrier second carrier 4' may be manufactured by integral molding.
In some embodiments of the present invention, as shown in fig. 15 and 16, the overall shape of the second fixing member 1 is L-shaped when viewed from the side view of the second fixing member 3', wherein the second base 301 is the long side of L and the second beam 303 is the short side of L. This is only one shape of the second fixing member 3', and in other embodiments, the overall shape of the second fixing member 3' may be any one of rectangle, square, trapezoid, etc. as will be readily apparent to those skilled in the art.
The second fixing member structure shown in fig. 12 to 16 is also applicable to the female connector, that is, the structure corresponding to the first fixing member, and the first fixing member and the second fixing member are only for distinguishing and describing the structures in the male connector and the female connector, and are actually parts with the same structure, and are not used for describing the sequence and the like. Likewise, the first carrier and the second carrier of the present invention are also the same.
The fixing piece provided by the invention is a component which can be independently separated from the cable connector, and can also be of an integrated structure with other components in the cable connector, and the fixing piece can be used for positioning the wiring terminal and playing a good role in protecting the terminal, and meanwhile, the fixing piece can be used for blocking the plastic punching into the main body of the cable connector, so that the problem of plugging of the connection male and female is avoided, and a favorable condition is provided for realizing the large-scale manufacturing automation of the cable connector.
The above preferable technical features can be used singly or in any combination, and the effect is better when the combination is used.
The latch and buckle structure of the present invention can be implemented by adopting the existing structure, so long as the objects of the latch and buckle can be matched, the latch and buckle structure is not limited to specific positions, and only some possible forms of embodiments are shown in the figure. The invention can be used in cable connectors for connection of electric vehicles, medical equipment, displays and the like, can ensure the product quality, and lays a foundation condition for realizing automation of the cable connectors.
