Abstract
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 the core components of electronic connectors used to achieve electrical connections and are responsible for transmitting current or signals. According to their structure, connector terminals mainly include pin-type, socket-type, blade-type, spring-loaded terminals, and IDC terminals. Among them, the socket-type, designed with a groove or elastic structure to clamp the pin, is a widely used electrical connector terminal structure.
[0003] In existing technologies, terminals typically employ a one-time locking structure. After the pin is inserted, pressing the one-time lock secures it firmly. These terminals usually consist of a bent square tube with an internally bent spring-loaded tab. There can be one or two spring-loaded tabs. The pin is secured by the stress between the spring-loaded tabs or the stress between the spring-loaded tab and the bottom wall, and then locked in place by a surface one-time lock to prevent loosening. In these terminals, the one-time lock is usually located at the top. Because the initial bending position requires the formation of the internal spring-loaded tab, after the top one-time lock is formed, a notch is created on the side, exposing the internal spring-loaded tab structure, making it extremely vulnerable to damage under external force.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0032] like Figure 1-3 As shown, the connector terminal proposed in this utility model includes:
[0033] A crimping part 100 and a slot 200 are provided; the crimping part 100 and the slot 200 are connected as a whole; in this utility model, the crimping part 100 and the slot 200 are integrally formed, and are formed by cutting and bending; wherein, the crimping part 100 includes a first connecting part 101 and a second connecting part 102; the first connecting part 101 clamps the conductive wire to ensure the stability of the conductive wire; preferably, the first connecting part 101 is composed of several rounded triangles arranged opposite each other; when the conductive wire is placed in the first connecting part 101, the several rounded triangles are bent to press the conductive wire; the second connecting part 102 includes crimping pieces arranged opposite each other; wherein, the crimping pieces can be rectangular; the conductor at the front end of the conductive wire is clamped by the relatively arranged crimping pieces, thereby ensuring the conductor connection strength; of course, the number of rounded triangles and the number of crimping pieces are subject to the actual situation, and this utility model will not further explain them.
[0034] like Figure 1 and Figure 3As shown, the slot 200 includes a winding structure formed by sequential bending; a first spring piece 201 and a second spring piece 202 are respectively provided on the winding structure, and the first spring piece 201 and the second spring piece 202 are placed inside the winding structure; specifically, after the winding structure is formed by processes such as stamping, the first spring piece 201 and the second spring piece 202 are placed inside the winding structure after being formed by bending and cutting; the winding structure protects the first spring piece 201 and the second spring piece 202; a primary lock 300 is formed on the winding structure, and in the pressed state, the primary lock 300 contacts the second spring piece 202; when the pin is inserted... After the pin enters the winding structure, it contacts the first spring piece 201. At this time, the primary lock 300 is operated to press the second spring piece 202 and make the second spring piece 202 contact the first spring piece 201. The pin is fixed by the cooperation of the primary lock 300, the second spring piece 202 and the first spring piece 201. It should be noted that a limiting shell can be set at the position of the pin. When the pin is inserted into the winding structure, the winding structure enters the limiting shell. After the limiting shell contacts the primary lock 300, the primary lock 300 moves to the position of the second spring piece 202, thereby squeezing the second spring piece 202.
[0035] The technical solution of this utility model forms a slot 200 by bending and winding a structure, which is then connected to the pin. A locking mechanism 300 is used to press the first spring 201 and the second spring 202 together, thus securing the pin stably inside the winding structure. The first spring 201 and the second spring 202 are placed inside the winding structure, protecting them during use. Compared with existing technologies, the first spring 201 and the second spring 202 are not exposed. When there is external force, it is blocked by the winding structure, preventing contact with the first spring 201 and the second spring 202, thus improving their stability and further increasing the overall stability.
[0036] like Figure 1 and Figure 2 As shown, the winding structure includes a first side 203, a second side 204, a third side 205, a fourth side 206, a fifth side 207, and a sixth side 208; and the first side 203, the second side 204, the third side 205, the fourth side 206, the fifth side 207, and the sixth side 208 are bent into shape in sequence.
[0037] The first spring 201 is disposed on the first side 203; the second spring 202 is disposed on the second side 204. Specifically, the first side 203 is bent and is in a horizontal state, while the first spring 201 is placed on the first side 203, and the end of the first spring 201 away from the first side 203 is provided with a curved section. When the pin is inserted, the first spring 201 contacts it, and under the action of the curved section, the first spring 201 always tends to be in the direction of the pin.
[0038] The second side 204 is bent to a vertical position and includes a connecting section 241, a cut section 242, and a supporting bottom edge 243. One end of the connecting section 241 is connected to the first side 203. The cut section 242 is formed on the connecting section 241. The supporting bottom edge 243 is located at the other end of the connecting section 241, and the third side 205 is connected to the supporting bottom edge 243. The second spring piece 202 is located on the connecting section 241 and is adjacent to the cut section 242. Figure 3 As shown, after the second spring piece 202 is formed, it is placed above the first spring piece 201. This allows the first spring piece 201 to be compressed by the second spring piece 202 when the primary lock 300 is operated. Furthermore, the second spring piece 202 includes a first arc-shaped segment 221 and a second arc-shaped segment 222, with opposite bending directions. In this invention, the curved segment on the first spring piece 201 is adapted to the second arc-shaped segment 222. This ensures that the second arc-shaped segment 222 contacts the curved segment when the second spring piece 202 is pushed by the primary lock 300, improving the stability of the first and second spring pieces 201 during operation. The opposite directions of the first and second arc-shaped segments 221 and 222 prevent excessive deformation of the second spring piece 202. Specifically, a first gap 400 exists between the second arc-shaped segment 222 and the first spring piece 201. The first gap 400 ensures that the first spring piece 201 has sufficient operating space after the pin is inserted.
[0039] The third side 205 is bent into a horizontal position and is parallel to the first side 203; there is a distance between the first side 203 and the third side 205; together with the second side 204 and the fourth side 206, they form an insertion space for inserting pins;
[0040] The fourth side 206 is bent to a vertical position, and the fourth side 206 is parallel to the second side 204; for example Figure 2 As shown, a fixing hole 261 is provided on the fourth side 206. In the connected state, the first side 203 is inserted into the fixing hole 261. Specifically, a protrusion adapted to the fixing hole 261 is provided on the first side 203. The protrusion on the first side 203 is inserted into the fixing hole 261, thereby enabling the first side 203 to be supported by the cooperation of the second side 204 and the fourth side 206, ensuring the stability of the first side 203, and thus ensuring the stability of the first spring piece 201.
[0041] In addition, a first anti-mistake protrusion 262 is provided on the fourth side 206; when inserting the conductive wire, the position of the first anti-mistake protrusion 262 can be used to determine whether the insertion direction of the conductive wire is correct, thus avoiding incorrect insertion direction of the conductive wire; at the same time, an observation hole 263 is provided on the fourth side 206; after production is completed or before use, the status of the first spring 201 and the second spring 202 can be obtained through the observation hole 263.
[0042] After being bent and formed, the fifth side 207 is in a horizontal state, and it is parallel to the first side 203 and the third side 205. A primary lock 300 is disposed on the fifth side 207, and in this invention, the primary lock 300 is positioned close to the second side 204 to ensure that the primary lock 300 corresponds to the second spring 202. After being bent and formed, the sixth side 208 is in a vertical state, and in this invention, the sixth side 208 is located within the cut section 242 on the second side 204, and... The second side 204 and the sixth side 208 are in the same plane. In this utility model, the second side 204 is cut and bent to form the second spring piece 202, and the cut position of the second side 204 forms a cut segment 242. When the sixth side 208 is formed, the cut segment 242 is filled, and the second side 204 is sealed by the sixth side 208. In turn, the second spring piece 202 is shielded by the sixth side 208, thereby protecting the second spring piece 202 and avoiding accidental contact with the second spring piece 202.
[0043] In addition, a second anti-mistake protrusion 281 is provided on the sixth side 208; the second anti-mistake protrusion 281 determines the insertion direction of the conductive wire; and when used in conjunction with the first anti-mistake protrusion 262, it can better prevent incorrect insertion direction of the conductive wire.
[0044] like Figure 2 As shown, the primary lock 300 is disposed on the fifth side 207 and the sixth side 208, and a second gap 500 exists between the primary lock 300 and the fifth side 207 and the sixth side 208; specifically, the primary lock 300 is formed at the connection between the fifth side 207 and the sixth side 208; in this utility model, the primary lock 300 is formed by cutting the fifth side 207 and the sixth side 208. Since the primary lock 300 has a right-angle structure after being formed, the primary lock 300 has greater strength; and due to the existence of the second gap 500, sufficient space can be provided for the movement of the primary lock 300.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
