[0038] Please refer to Figures 1 to 4 This utility model provides a connector female socket, including a female socket plastic body 10, a switch spring 30 disposed on the female socket plastic body 10, and a plurality of female end terminals 20 arranged on the female socket plastic body 10; the female end terminal 20 includes a solder end 22, a free end 23, and a terminal body 21 connected between the solder end 22 and the free end 23;
[0039] At least two female terminals 20 have protrusions 231 on their free ends 23, which are used to abut against the male terminal when the male terminal is inserted.
[0040] The connector female socket includes a female socket plastic body 10, which is a hollow structure with multiple female terminals 20 evenly arranged inside. The multiple female terminals 20 are arranged linearly along the width direction of the insulating plastic body.
[0041] In this embodiment, a detection pair is formed in the female terminal 20 by providing a protrusion 231 on the surface of the free end of at least two female terminal 20.
[0042] When the male terminal is not inserted, the female terminal 20 is in its natural state, and the female terminal 20 with the protrusion 231 is conductive with the switch spring 30, thus short-circuiting the female terminal 20. When the male terminal is inserted, the male terminal first contacts the protrusion 231, and the female terminal 20 with the protrusion 231 is disconnected from the switch spring 30, thereby triggering a detection signal. It can be understood that this detection signal can also be used in practical applications to send instructions to the downstream circuit to execute the next operation.
[0043] In summary, the female terminal 20 provided in this embodiment can achieve fast and accurate insertion status recognition without increasing assembly difficulty.
[0044] Specifically, the female terminal 20 includes a first layer structure and a second layer structure, which are spaced apart, and the first layer structure and the second layer structure have a connecting and fixing part in the middle to ensure the relative position of the two layers structure is stable.
[0045] In both the first and second layer structures, the welding end 22 is an L-shaped bend relative to the terminal body 21, which enables the female terminal 20 to be firmly welded to the PCB, enhancing the reliability of the connection.
[0046] The welding ends 22 in the first and second layer structures are staggered. This staggered arrangement helps to avoid mutual interference during welding and improves welding efficiency and quality.
[0047] Furthermore, in both the first and second layer structures, the bending angle of the free end 23 relative to the terminal body 21 is the same; specifically, the bending angle is an acute angle.
[0048] Understandably, a uniform bending angle helps ensure the consistency and stability of the female terminal 20.
[0049] In addition, in both the first and second layer structures, the connection between the free end 23 and the terminal body 21 is a rounded transition part. The rounded transition part is conducive to dispersing stress and avoiding breakage due to external force during use.
[0050] In this embodiment, optionally, one of the free ends 23 of the first layer structure and the second layer structure is provided with a protrusion 231; in addition, each female terminal 20 in the connector socket includes at least one pair of detection pairs, and each pair of detection pairs includes two female terminals 20 provided with protrusions 231. It is understood that the pair of detection pairs is used to form a conduction circuit with the switch spring 30 in the female connector.
[0051] Specifically, the switch spring 30 is provided with a first abutting part 322. When the female terminal 20 is in a free state, the protrusion 231 abuts against the first abutting part 322 to form a closed circuit.
[0052] The male terminal has a second abutment 41 at the insertion end. When the male terminal is inserted, the second abutment 41 abuts against the protrusion 231, causing the female terminal 20 with the protrusion 231 to disconnect from the switch spring 30.
[0053] For example, when the female terminals 20 arranged in the female plastic body 10 are arranged as one PIN per layer, when there are 8 PINs, the second PIN and the seventh PIN are a layer in the female terminal 20 with a protrusion 231. That is, the second PIN and the seventh PIN are used to abut against the conduction switch spring 30 when the male terminal is not inserted, and abut against the male terminal through the protrusion 231 when the male terminal is inserted.
[0054] In practical applications, the female terminal 20 with the protrusion 231 can be connected to a signal light; when the female terminal 20 is in contact with the switch spring 30, the female terminal 20 is short-circuited, so the signal light does not light up; when the male terminal is inserted, the female terminal 20 with the protrusion 231 is disconnected from the switch spring 30, so the female terminal 20 becomes conductive and the signal light lights up.
[0055] Please refer to the reference. Figures 1 to 5 This utility model also provides a connector, including a female connector and a male connector 40.
[0056] The connector female socket includes a female socket plastic body 10, a switch spring 30 disposed on the female socket plastic body 10, and a plurality of female terminals 20 arranged on the female socket plastic body 10; the female terminal 20 includes a solder end 22, a free end 23, and a terminal body 21 connected between the solder end 22 and the free end 23.
[0057] At least two female terminals 20 have protrusions 231 on their free ends 23, which are used to abut against the male terminal when the male terminal is inserted.
[0058] The connector female socket includes a female socket plastic body 10, which is a hollow structure with multiple female terminals 20 evenly arranged inside. The multiple female terminals 20 are arranged linearly along the width direction of the insulating plastic body.
[0059] The switch spring 30 is provided with a first abutting part 322. When the female terminal 20 is in a free state, the female terminal 20 with the protrusion 231 abuts against the first abutting part 322 to form a closed circuit.
[0060] The male terminal has a second abutment 41 at the insertion end. When the male terminal is inserted, the second abutment 41 abuts against the protrusion 231, causing the female terminal 20 with the protrusion 231 to disconnect from the switch spring 30.
[0061] For example, when the female terminals 20 arranged in the female plastic body 10 are arranged as one PIN per layer, when there are 8 PINs, the second PIN and the seventh PIN are a layer with a protrusion 231 in the protrusion. That is, the second PIN and the seventh PIN are used to abut against the conduction switch spring 30 when the male terminal is not inserted, and abut against the male terminal through the protrusion 231 when the male terminal is inserted.
[0062] It is understandable that, due to the protrusion 231, the male terminal does not need to be structurally adjusted, and any male terminal structure can be adapted to the female terminal 20 in this embodiment and achieve the effect of insertion detection.
[0063] Furthermore, the female plastic body 10 is provided with a switch spring 30. One end of the switch spring 30 is connected to the female plastic body 10 through a fixing piece 31, and the other end of the switch spring 30 is bent to form a hanging ear 32. The hanging ear 32 includes a first abutting part 322. When the female terminal 20 is in a free state, the hanging ear 32 is pressed towards the fixing piece 31 by the female terminal 20 which is provided with a protrusion 231.
[0064] In this embodiment, when the female terminal 20 is in a free state, the lug 32 is pressed against the female terminal 20 and pushed towards the fixing piece 31. When the male terminal is inserted, the second abutting part 41 abuts against the protrusion 231, causing the female terminal 20 to disconnect from the switch spring 30.
[0065] In practical applications, the female terminal 20 with the protrusion 231 can be connected to a signal light; when the female terminal 20 is in contact with the switch spring 30, the female terminal 20 is short-circuited, so the signal light does not light up; when the male terminal is inserted, the female terminal 20 with the protrusion 231 is disconnected from the switch spring 30, so the female terminal 20 becomes conductive and the signal light lights up.
[0066] Furthermore, the first contact portion 322 has a hook-shaped structure. The arc portion formed by the hook-shaped structure abuts against the free end 23, which helps to increase the contact area, make the connection more stable, ensure the conduction effect, and improve the detection accuracy when the male seat is inserted.
[0067] In addition, the surface of the switch spring 30 is provided with a recess 321, which can increase the elasticity and deformation capability of the switch spring 30, ensuring that the switch spring 30 can work normally during the insertion and removal of the male terminal, and accurately realize the switching of conduction and disconnection.
[0068] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
