The connecting portion 120 is a flat plate-shaped structure that is vertically disposed, and the first elastic piece 130 and the second elastic piece 140 are fixed to a first end (i.e., the top in the figure).

Referring to fig. 1, the first elastic sheet 130 is a continuously bent plate-shaped structure and includes a first bending section 131, a first connecting section 132 and a first abutting section 133 connected in sequence. One end of the first bending section 131 is connected to the first end of the connecting portion 120 in an inclined manner, and the other end extends upward and rearward, and is connected to a first connecting section 132. The first connecting section 132 is entirely parallel to the connecting portion 120, and has one end connected to the first bending section 131 and the other end extending away from the connecting portion 120. One end of the first abutting section 133 is connected to one end of the first connecting section 132 away from the first bending section 131 in an inclined manner, and the other end extends upward and rearward. It is understood that the first connecting section 132 is not necessarily parallel to the connecting portion 120, and the first connecting section 132 may also be at an angle to the connecting portion 120.

The first abutting section 133 is used for abutting against an external counter insert to realize conductive connection, and further, a first supporting section 134 is further arranged between the first connecting section 132 and the first abutting section 133. One end of the first supporting section 134 is obliquely connected with the tail part of the first connecting section 132, and the other end extends forwards and upwards and is connected with the first abutting section 133, so that a Z-shaped structure is formed among the first connecting section 132, the first supporting section 134 and the first abutting section 133.

The second connecting section 142 is entirely parallel to the connecting portion 120, and has one end connected to the second bending section 141 and the other end extending away from the connecting portion 120. One end of the second abutting section 143 is connected to one end of the second connecting section 142 away from the second bending section 141 in an inclined manner, and the other end extends upward and forward. That is, the inclination directions of the ends of the second elastic sheet 140 and the first elastic sheet 130 close to the connecting portion are opposite to the inclination directions of the connecting portion 120; the end of the abutting section of the second elastic sheet 140 and the first elastic sheet 130 far away from the connecting end extends back to back. It is understood that the second connecting section 142 is not necessarily parallel to the connecting portion 120, and the second connecting section 142 may also have an angle with the connecting portion 120.

The second abutting section 143 is configured to abut against an external counter insert to achieve an electrically conductive connection, and further, a second supporting section 144 is further disposed between the second connecting section 142 and the second abutting section 143. One end of the second supporting section 144 is connected to the tail of the second connecting section 142 in an inclined manner, and the other end extends rearward and upward and is connected to the second abutting section 143, so that an inverted "Z" shaped structure is formed among the second connecting section 142, the second supporting section 144 and the second abutting section 143. When the external counter insert abuts against the end of the second abutting section 143, the second abutting section 143 is bent downward, and the second supporting section 144 can provide a reverse elastic force to the second abutting section 143, so as to prevent the second abutting section 143 from being easily disabled due to no support in the long-term abutting process.

In this embodiment, the first elastic sheet 130 and the second elastic sheet 140 are formed by tearing and bending the plate-shaped structure integrally connected to the connecting portion 120 for multiple times in the back and front directions, and the two elastic sheets are bent at the same position, and at this time, the intersecting lines of the two elastic sheets and the connecting portion are collinear. It can be understood that, in other embodiments of the present invention, the two elastic pieces can be bent at different positions, and the intersecting lines of the two elastic pieces and the connecting portion are parallel; or the two elastic sheets are respectively bent towards the right front direction and the left rear direction, and a certain included angle is formed between the intersection lines of the two elastic sheets and the connecting part at the moment. It should be understood that "side-by-side" in the above-described embodiments means aligned in a row along the direction in which the above-described intersecting lines extend, and "offset" in the above-described embodiments means offset along the direction of the intersecting lines; in other embodiments of the present invention, "side by side" may also mean that the lines are arranged in a row along a direction perpendicular to the intersection line, and correspondingly, "staggered" may also mean that the lines are staggered along a direction perpendicular to the intersection line.

Referring to fig. 1, the fixing portion 110 is fixed to a second end of the connecting portion 120 away from the first end, and is generally cylindrical and perpendicular to the connecting portion 120. The fixing portion 110 is used to fix the terminal 100 on the insulating body, and is electrically connected to a circuit board (not shown) as a signal input terminal.

When the external plug-in unit is connected to the first connecting section 133 and the second connecting section 143, the signal output from the circuit board is transmitted to the connecting section 120 through the fixing section 110, and then separately transmitted to the plug-in unit through the first elastic sheet 130 and the second elastic sheet 140, so as to realize signal transmission.

Compare with the U-shaped terminal on the existing market, two shell fragments of the terminal that this embodiment provided all extend the formation from the first end slope of connecting portion, have saved crossbeam structural part on the one hand, do benefit to reduce cost, and on the other hand has also reduced the whole space that occupies of terminal.

It can be understood that, even though the relative connection portion of the first elastic sheet and the second elastic sheet in the above embodiment is bent in opposite directions, in other embodiments of the present invention, the first elastic sheet and the second elastic sheet may be bent in the same direction, that is, the inclination directions of the first elastic sheet and the second elastic sheet relative to the connection portion are the same; the ends of the abutting sections of the two elastic sheets far away from the connecting section can also extend oppositely.

The utility model also provides an electric connector, this electric connector includes insulator and foretell terminal. A plurality of the terminals are arranged in parallel in a lateral direction (i.e., a direction in which the intersection extends) and in a vertical direction (i.e., a direction perpendicular to the intersection). In some embodiments, the bending directions of the elastic pieces of the terminals are the same, and the terminals are often formed in the same batch, that is, generally, the left elastic piece of each terminal is formed into the same structure with the same parameters, and the right elastic piece of each terminal is formed into the same structure with the same parameters; if the molding of the left and right spring plates in the molding process has differences, the stress of the terminals is unbalanced when the plug-in connector is matched with the electric connector, so that the plug-in connector is easy to be wholly upwards or downwards dislocated. Further, in order to avoid the above situation, the terminals in the electrical connector provided by this embodiment include two types of terminals, and the bending directions of the spring pieces of the two types of terminals are just opposite.

Referring to fig. 3 to 5, which respectively show a perspective view of the electrical connector in two directions and a partially enlarged view at a position a, the insulating body 200 is a square block, and a plurality of terminals 100 are fixed to the insulating body 200, and are arranged on the insulating body 200 along a straight line and sequentially arranged in at least one row. The terminals 100 distributed in the same row along the transverse direction (and the direction in which the intersection extends) include the

terminals

100a and 100b, and the

terminals

100a and 100b are arranged at intervals. The main differences between the terminal 100a and the terminal 100b are: the left spring plate of the terminal 100a is bent upward, the right spring plate is bent downward, the left spring plate of the terminal 100b is bent downward, and the right spring plate is bent upward; the terminal 100a and the left spring plate of the terminal 100b are formed to have the same structure by the same parameters, and the terminal 100a and the right spring plate of the terminal 100b are formed to have the same structure by the same parameters.

In this embodiment, the

terminals

100a and 100b are arranged at intervals in a manner that one terminal 100a and one terminal 100b are arranged, and between adjacent terminals in the same row, two elastic pieces located inside are inclined in the same direction relative to the connecting portion, and the inclination direction of two elastic pieces located outside relative to the connecting portion is opposite to that of the two elastic pieces inside.

Through the arrangement mode, the two sides of the connecting part are provided with the same terminal structures, and even if the two elastic sheets of the same terminal are molded to have differences, the stress of each elastic sheet is uniform, so that the integral dislocation of the plug-in unit can be effectively avoided.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; within the idea of the invention, also technical features in the above embodiments or in different embodiments can be combined, steps can be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
