Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a connector terminal. Background Technology

[0002] Connector terminals are typically used to connect two wire harnesses. Two wire harnesses extending from a product or device are connected to the male and female terminals of a connector, respectively. The two wire harnesses are then connected by mating the male and female terminals. Connectors are reliably used in electronic equipment, automotive manufacturing, and industrial fields. However, depending on the application of the male and female terminals, their structures and mating methods vary slightly. Common mating methods include mating between the connector shaft and the socket, or mating between the prong and the slot.

[0003] Regardless of whether it is a male or female connector for a pin and socket, or a male or female connector for a blade and slot, users usually conduct random checks on some products after purchase to test whether they can be properly connected. Similarly, operators usually test the reliability of the connection before connecting it to the wiring harness during the installation process.

[0004] However, in existing male and female connector designs, the female connector's slot structure involves a spring-loaded mechanism to clamp the connector. Part of this spring-loaded mechanism involves a bend formed on the back side of the female connector, with the bend abutting against a side of the back side furthest from the female connector. The space between the bends is the slot / interlocking space for connector insertion. However, when using this type of slot, if the purchased female connector (some manufacturers only sell female connectors, specifically designed for existing male connector designs) and the male connector are not... When a manufacturer produces a product, users can conduct a certain amount of testing after receiving it. However, if the thickness of the insert does not match the socket (i.e., exceeds the maximum insertion thickness that the socket can withstand), even if the insert can be inserted normally, the socket will not spring back to its original position after the insert is removed. This is similar to the bent part being deformed by the insert after being subjected to the mismatch. This can lead to damage to the female end. Or, if the user does not find that the socket has been deformed after testing, when it is used in the circuit, data transmission may be intermittent or there may be no power at all, resulting in the connector becoming unreliable. Summary of the Invention

[0005] In view of the above shortcomings, the present invention provides a connector terminal that can reliably connect to the male end and will not affect the data signal transmission due to accidental deformation.

[0006] To achieve the above objectives, this utility model employs a connector terminal, including a crimping portion and a plugging portion. The crimping portion includes a crimping core and a crimping wire. The plugging portion includes a plugging base plate, plugging side plates distributed on both sides of the plugging base plate, and a plugging top plate opposite to the plugging base plate. The plugging portion, through the plugging base plate, the two side plugging plates, and the plugging top plate opposite to the plugging base plate, forms a plug-in interface for inserting an external male terminal. A spring-loaded portion is formed on the plugging portion relative to the plug-in interface. The external male terminal plug inserted into the plug-in interface is stopped and positioned within the connector terminal by the contact of the spring-loaded portion. A support foot is also formed on the plugging portion, which abuts against the spring-loaded portion on the external male terminal plug, thus forming a deformation-resistant stop.

[0007] The present invention is further configured such that the spring-loaded part is a spring-loaded tongue connected to the plug-in base plate and forming towards the plug-in interface. The end of the spring-loaded tongue extending into the plug-in interface abuts against the plug-in top plate relative to the end away from the plug-in base plate. A plug-in space is formed between the spring-loaded tongue and the plug-in top plate for inserting a plug-in piece on the external male end. The support foot extends from the spring-loaded tongue toward the plug-in base plate. A support foot movable gap is formed between the support foot and the plug-in base plate.

[0008] The present invention is further configured such that the spring-loaded part is a spring-loaded tongue connected to the plug-in base plate and forming towards the plug-in interface. The end of the spring-loaded tongue extending into the plug-in interface abuts against the plug-in top plate relative to the end away from the plug-in base plate. A plug-in space is formed between the spring-loaded tongue and the plug-in top plate for inserting a plug-in piece on the external male end. The support foot extends from the plug-in base plate toward the side of the spring-loaded tongue. A support foot movable gap is formed between the support foot and the plug-in base plate.

[0009] The present invention is further configured such that the spring-loaded part is a spring-loaded tongue connected to the top plate of the plug-in interface and extending into the plug-in interface. The end of the spring-loaded tongue that extends into the plug-in interface abuts against the bottom plate of the plug-in interface. A plug-in space is formed between the spring-loaded tongue and the bottom plate of the plug-in interface for inserting a prong from an external male terminal. The support leg extends from the spring-loaded tongue toward the top plate of the plug-in interface. A support leg movable gap is formed between the support leg and the top plate of the plug-in interface.

[0010] The present invention is further configured such that the spring-loaded part is a spring-loaded tongue connected to the top plate of the plug-in interface and extending into the plug-in interface. The end of the spring-loaded tongue that extends into the plug-in interface abuts against the bottom plate of the plug-in interface. A plug-in space is formed between the spring-loaded tongue and the bottom plate of the plug-in interface for inserting a prong from an external male terminal. The support leg extends from the spring-loaded tongue toward the top plate of the plug-in interface. A support leg movable gap is formed between the support leg and the top plate of the plug-in interface.

[0011] The present invention is further configured such that the support feet are vertically distributed on the side facing the plug-in base plate.

[0012] The present invention is further configured such that the support feet are vertically distributed on the side facing the plug-in top plate.

[0013] The beneficial effects of this utility model are as follows: By including a crimping part and a plugging part in the connector terminal, the crimping part includes a crimping core for crimping and limiting wire harnesses with the outer sheath not stripped, and a crimping wire for crimping and limiting wire harnesses with the outer sheath stripped. The plugging part includes a plug interface for inserting a prong into the male end, and a spring-loaded part for clamping the prong after insertion. In addition, the plugging part also includes corresponding support feet. That is, when the prong of the male end is inserted into the plug interface, it is elastically pressed against one side of the prong by the spring-loaded part, and the corresponding support feet can effectively prevent the spring-loaded part from being deformed by excessive pressure from the prong. In cases where the support feet are involved, the space for inserting the prongs into the male terminal of the connector is limited. If the prongs are too thick, exceeding the maximum allowable insertion space, they will be blocked outside the connector. This effectively prevents the spring-loaded part from deforming due to the insertion of an unsuitable prong, thus avoiding damage to the female terminal. Furthermore, if the female terminal connected to the circuit is not found to have deformed insertion slots, data transmission may be intermittent or power failure may occur during use, leading to unreliable connectors.

[0016] Figure 3 yes Figure 2 AA sectional view;

[0017] Figure 4 yes Figure 3An enlarged schematic diagram. Detailed Implementation

[0018] like Figure 1-4 As shown, a specific embodiment of this utility model is a connector terminal, including a crimping part 1 and a plugging part. The crimping part 1 includes a crimping core foot 12 and a crimping wire foot 11. The plugging part includes a plugging base plate 5, plugging side plates 3 distributed on both sides of the plugging base plate 5, and a plugging top plate 2 opposite to the plugging base plate 5. The plugging part forms a plug interface b for inserting an external male terminal through the plugging base plate 5, the plugging side plates 3 on both sides, and the plugging top plate 2 opposite to the plugging base plate 5. A spring-loaded part 4 is formed on the plugging part relative to the plug interface b. The external male terminal plug inserted into the plug interface b is stopped by the spring-loaded part 4, forming a plugging limit in the connector terminal. A support foot 6 is also formed on the plugging part. The support foot 6 is used to abut against the spring-loaded part 4 on the external male terminal plug, forming a deformation-resistant limit.

[0019] The connector terminals include a crimping portion 1 and a mating portion. The crimping portion 1 includes a crimping core 12 for crimping and limiting wire harnesses with unstripped outer sheaths and a crimping wire pin 11 for crimping and limiting wire harnesses with stripped outer sheaths. The mating portion includes a mating interface b for inserting a prong into the male end and a spring-loaded portion 4 for clamping the prong after insertion. A corresponding support foot 6 is also included on the mating portion. When the prong of the male end is inserted into the mating interface b, it is elastically pressed against one side of the prong by the spring-loaded portion 4. The corresponding support foot 6 effectively prevents the spring-loaded portion 4 from being excessively compressed by the prong and deforming. That is, after the support foot 6 is involved, the space for inserting the male terminal in the connector b can be limited. When the thickness of the insert is too thick, such as exceeding the maximum allowable insertion space a after the support foot 6 is involved, the insert will be blocked outside the connector b. This effectively avoids the deformation of the spring part 4 due to the insertion of an unsuitable insert, which would cause damage to the female terminal. At the same time, if the female terminal connected to the circuit is not found to have deformed insertion slot, when it is used, data transmission may be intermittent or there may be no power supply, which will lead to the connector becoming unreliable.

[0020] like Figure 1 , 2As shown in Figure 4, the design of the spring-loaded part 4 is as follows: it can be a spring-loaded tongue connected to the insertion base plate 5 and forming towards the insertion interface b. Simultaneously, the end of the spring-loaded tongue extending into the insertion interface b abuts against the insertion top plate 2 relative to the end furthest from the insertion base plate 5. Between the spring-loaded tongue and the insertion top plate 2, an insertion space a is formed for inserting a prong onto an external male terminal. The support leg 6 is a structure designed to extend from the spring-loaded tongue towards the insertion base plate 5. Simultaneously, a support leg movement gap c is formed between the support leg 6 and the insertion base plate 5. This design is the preferred design scheme. Correspondingly, the spring-loaded part 4 is also a spring-loaded tongue connected to the insertion top plate 2 and forming towards the insertion interface b. The tongue extends into the insertion interface b, and the end of the tongue that is away from the insertion top plate 2 abuts against the insertion bottom plate 5. The insertion space a for inserting the external male end is formed between the tongue and the insertion bottom plate 5. In addition to the above, the support foot 6 can also extend from the tongue toward the insertion top plate 2. Furthermore, the corresponding support foot movement gap c is located between the support foot 6 and the insertion top plate 2. Thus, the setting of the spring pressing part 4 or the support foot 6 can be designed according to the actual situation, which greatly improves the diversity of the design and greatly reduces the limitations.

[0021] like Figure 3-4 As shown, due to the design of the support foot 6, it can be a structural design that extends from the spring tongue toward the side of the insertion base plate 5, or it can be a structural design that extends from the spring tongue toward the side of the insertion top plate 2. However, when the above two schemes are involved, in order to ensure the reliability of the design, the designed support foot 6 must be distributed vertically.
