[0028] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0029] Please combine Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a multi-contact male and female connector structure 10 includes: a male connector 100 and a female connector 200, the male connector 100 includes a male base 110 and a male terminal 120, the male terminal 120 is arranged on the male base 110, one end of the male terminal 120 is bent to form a first connecting arm 121 and a second connecting arm 122, and a plurality of elastic abutting blocks 121a are arranged on the first connecting arm 121; the female connector 200 includes a female base 210 and a female terminal 220, the female terminal 220 is arranged on the female base 210, one end of the female terminal 220 is bent to form a first clamping arm 221 and a second clamping arm 222, and a clamping cavity 223 is formed between the first clamping arm 221 and the second clamping arm 222; when the male terminal 120 is inserted into the clamping cavity 223, each elastic abutting block 121a is respectively abutted against the first connecting arm 121, and the second connecting arm 122 is abutted against the second clamping arm 222.

[0030] It should be noted that a first connecting arm 121 and a second connecting arm 122 are formed by bending the male terminal 120, and a first clamping arm 221 and a second clamping arm 222 are formed by bending the female terminal 220, and a clamping cavity 223 is formed between the first clamping arm 221 and the second clamping arm 222, so that the male terminal 120 can be inserted into the clamping cavity 223 to form a connection with the female terminal 220. Furthermore, a plurality of elastic abutment blocks 121a are provided on the first connecting arm, so that multi-point contact is formed between the first connecting arm 121 and the first clamping arm 221, and a contact point is also formed between the second clamping arm 222 and the second connecting arm 122. In this way, multi-point contact can be formed between the male terminal 120 and the female terminal 220. In this way, compared with the existing connector with only a single contact point, by increasing the contact points, signal transmission can be better and current transmission can be more stable, so that the conductivity between the male connector 100 and the female connector 200 is better.

[0031] Specifically, when the male connector 100 is plugged into the female connector 200, since one end of the male terminal 120 is bent to form the first connecting arm 121 and the second connecting arm 122, and the first connecting arm 121 and the second connecting arm 122 are overall U-shaped structures, when the male terminal 120 is squeezed into the clamping cavity 223, the first connecting arm 121 and the second connecting arm 122 are compressed and approach each other. At the same time, the female terminal 220 is squeezed, so that the first clamping arm 221 and the second clamping arm 222 are separated from each other, so as to increase the opening end of the clamping cavity 223, thereby making the male terminal The male terminal 121 can be smoothly inserted into the clamping cavity 223. After the male terminal 120 and the female terminal 220 are plugged in, the first connecting arm 121 and the first clamping arm 221 rebound, so that the elastic abutment block 121a on the first connecting arm 121 can be tightly abutted against the first clamping arm 221. Similarly, the second connecting arm 122 and the second clamping arm 222 rebound and tightly abut against each other. In this way, by increasing the number of contact points and the effect of the rebound force, not only can metal fatigue be prevented, but also the transmission signal can be better and the transmission current can be more stable, and the conductivity can be better. It should also be noted that the male terminal 120 is provided with two groups, each group of male terminals is arranged in an array, and correspondingly, the female terminals 220 that are matched with the male terminal 120 are also provided with two groups, each group of female terminals 220 is arranged in an array, so that the conductivity between the female connector 200 and the male connector 100 can be further enhanced.

[0032] Specifically, see Figure 3 and Figure 6 As shown, one end of the elastic supporting block 121a is disposed on the first connecting arm 121, and the other end of the elastic supporting block 121a extends in a preset circumferential direction, so that the elastic supporting block 121a has an arc-shaped structure.

[0033] It should be noted that the other end of the elastic supporting block 121a extends in a preset circumferential direction, and at the same time, the extended position is at a certain preset distance from the first connecting arm 121, so that the elastic supporting block 121a can have a certain space to retract inward in the direction close to the first connecting arm 121 when it is squeezed. That is, the elastic supporting block 121 can have elastic force, so when the male terminal 120 is squeezed into the female terminal 220, the elastic supporting block 121a can retract under pressure. After being installed in place, the elastic supporting block 121a rebounds and fits tightly with the first clamping arm 221 to improve the conduction performance.

[0034] For further information, see Figure 3 and Figure 8 As shown, a side surface of the first clamping arm 221 facing the first connecting arm 121 is provided with an escape groove 221 a , and each elastic supporting block 121 a is accommodated in the escape groove 221 a .

[0035] It should be noted that, by providing an avoidance groove 221a on the first clamping arm 221 and accommodating the elastic abutting block 121a in the avoidance groove 221a, the avoidance groove 221a plays a certain limiting role on the elastic abutting block 121a, so that the first connecting arm 121 and the second connecting arm 122 on the male terminal 120 can be prevented from retracting and disengaging from the clamping cavity 223 of the female terminal 220 to a certain extent, so that the connection stability between the male connector 100 and the female connector 200 can be further improved. Furthermore, in order to facilitate the male terminal 120 to quickly enter the avoidance groove 221a or to make the male terminal 120 quickly disengage from the avoidance groove 221a, the two sides of the avoidance groove 221a are guide inclined structures.

[0036] See also Figure 3 , Figure 8 and Fig. 9 As shown, in one embodiment, one end of the second clamping arm 222 is connected to the first clamping arm 221 , and the other end of the second clamping arm 222 is folded inward toward the clamping cavity 223 to form an abutment portion 222a , which abuts against the second connecting arm 122 .

[0037] It should be noted that the other end of the second clamping arm 222 is folded inwardly toward the clamping cavity 223 to form an abutment portion 222a. The inward folding method is adopted to ensure that the second clamping arm 222 has sufficient abutment strength to ensure the assembly stability between the male terminal 120 and the female terminal 220.

[0038] Furthermore, a supporting protrusion 122 a is provided on a side surface of the second connecting arm 122 facing the supporting portion 222 a , and the supporting protrusion 122 a is in contact with the second connecting arm 122 .

[0039] It should be noted that in order to further increase the number of contact points between the male terminal 120 and the female terminal 220, so as to further enhance the transmission signal and improve the stability of current transmission, the other end of the second clamping arm 222 is folded inward toward the clamping cavity 223 to form an abutment portion 222a, and at the same time, a supporting protrusion 122a is provided on the second connecting arm 122, and the end of the abutment portion 222a abuts against each other, thereby further increasing the contact points, so that there are two contact points between the second connecting arm 122 and the second clamping arm 222, thereby improving the signal and current conduction performance.

[0040] See also Figure 7 As shown, a limiting groove 122b is defined on one side surface of the second connecting arm 122 facing the abutting portion 222a, and a portion of the abutting portion 222a abuts against the limiting groove 122b.

[0041] It should be noted that, by providing the limiting groove 122b to abut against the abutting portion 222a, the limiting groove 122b can limit the abutting portion 222a, thereby preventing the male terminal 120 from retracting and separating from the female terminal 220, thereby ensuring the connection stability between the male terminal 120 and the female terminal 220. Furthermore, the side walls around the limiting groove 122b are guiding inclined surfaces, thereby increasing the opening space of the limiting groove 122b, and enabling the abutting portion 222a to quickly enter the limiting groove 122b.

[0042] See also Figure 8 and Fig. 9 As shown, one end of the female terminal 220 away from the first clamping arm 221 is bent to form a female terminal foot 224 , and a stepped structure 224 a is provided on the upper surface of the female terminal foot 224 .

[0043] It should be noted that the female terminal pin 224 is connected to the PCB board 300 by welding. In order to improve the tin-climbing ability of the female terminal pin 224 during welding, that is, to make the tin-applying ability of the female terminal pin 224 stronger and the solder paste can adhere more to the female terminal pin 224, a step structure 224a is added to the upper surface of the female terminal pin 224. In this way, the quality of welding can be further improved.

[0044] Furthermore, the end of the female terminal pin 224 is provided with a plurality of protrusions 224b, and each protrusion 224b is provided at intervals. That is, by providing a plurality of protrusions 224b, the area of ​​soldering is further increased, that is, the contact area between the solder paste and the female terminal pin 224 is made larger, so that the effect of transmitting signals and transmitting current can be better. In this embodiment, the structure of the male terminal pin on the male terminal 120 is the same as the structure of the female terminal pin 224. Further, in this embodiment, the step structure 224a is provided on the upper surface of the protrusion 224b.

[0045] In one embodiment, please refer to Figure 3 and Figure 5 As shown, a female base grounding plate (not shown) is provided on the female base 210, and the lower surface of the female base grounding plate extends away from the lower surface of the female terminal foot 224 to form a preset distance between the lower surface of the female base grounding plate and the lower surface of the female terminal foot 224.

[0046] It should be noted that the female base grounding plate is arranged at the bottom of the female base 210, and the female base grounding plate guides the static electricity to the ground, so as to prevent electrostatic injury. At the same time, a preset distance is formed between the lower surface of the female base grounding plate and the lower surface of the female terminal pin 224, that is, the female base grounding plate is higher than the lower surface of the female terminal pin 224, so that the female base connecting plate can be inserted into the PCB board 300 (the PCB board has a corresponding positioning hole), then, before the female base connector 200 is soldered to the PCB board, the female base grounding plate is first inserted into the PCB board 300 to form a pre-positioning operation for the female base connector 200, and then during soldering, the female base connector 200 can be prevented from deviating, so even if a slight vibration occurs during the soldering process, the female base connector 200 will not be offset, so that the problem of the female base connector 200 being offset and causing poor signal transmission can be avoided. Furthermore, it should be noted that the mother socket grounding plate is a circular structure, and there are two mother socket grounding plates, which are symmetrically arranged at the bottom of the mother base 210, so even if the mother socket connector 200 is rotated 180 degrees before being soldered to the PCB board, it can still be installed normally without affecting the function; in addition, it should be noted that the depth of the positioning hole opened on the PCB board needs to take into account the embedding depth of the mother socket grounding plate and the thickness of the required amount of solder paste after being flattened.

[0047] For further information, please refer to 2. Figure 4 and Figure 5 As shown, a male base 110 is provided with a male grounding plate 111. The male grounding plate 111 guides static electricity to ground to avoid static electricity breakdown; at the same time, a positioning groove 211 is provided on the side of the female base 200 away from the female grounding plate. Correspondingly, part of the male grounding plate 111 is connected to the male base 100, and part of the male grounding plate 111 extends in a direction away from the male grounding plate 111. After the male connector 100 and the female connector 200 are connected, the part of the male grounding plate 111 extending out is inserted into the positioning groove 211 on the female base 200, thereby positioning the male connector 100, making the position more accurate when pressing the male connector 100, which is conducive to the automated CCD alignment assembly. Similarly, there are two male grounding plates 111, and they are circular structures. At the same time, the two male grounding plates 111 are symmetrically arranged, so they can be connected normally even if they are rotated 180 degrees.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
