At present, some connectors applied to the industrial field have the characteristics of more plugging times and large current, and have higher requirements on the connection quality and the service life of the connection terminals. On the one hand, the tighter the conducting strip of the connecting terminal clamps the plug, the higher the quality of connection is, and the working requirement of large current can be adapted more. On the other hand, the friction between the plug and the conducting strip in the plugging process is increased by tight clamping, so that the abrasion of the connecting terminal is aggravated, and the service life of the connector is shortened.

Therefore, the current connector cannot compromise the two problems of connection quality and service life. In view of the above, embodiments of the present application provide a connector with improved connection terminals, which combines the connection quality and the service life of the connector by providing overlapping tooth portions on a conductive sheet.

For the purpose of understanding, the detailed description of the embodiments of the present application is provided below with reference to the accompanying drawings.

Referring to fig. 1 to 3, fig. 1 is a perspective view of a connector with improved connection terminals according to an embodiment of the present disclosure; fig. 2 is a schematic view of a connector with a modified connection terminal provided in an embodiment of the present application after an upper housing is opened; fig. 3 is a schematic diagram of a connection terminal in a connector with an improved connection terminal according to an embodiment of the present disclosure. As shown in fig. 1 to 3, a connector with an improved connection terminal provided in an embodiment of the present application includes: the connecting terminal 20 comprises two oppositely arranged conductive assemblies 100, and the two conductive assemblies 100 are used for clamping power-on plugs of electric equipment from two sides; each conductive assembly 100 comprises at least two conductive sheets, and teeth parts for electric connection are formed at the ends of the conductive sheets; in the same conductive assembly 100, the teeth of at least two conductive sheets are staggered.

In this embodiment, the lower end of the conductive plate is connected to the connector circuit, and the upper end of the conductive plate forms a tooth-shaped portion. When the plug of the electric equipment is inserted, the tooth-shaped part on the conducting strip contacts and clamps the plug, and circuit connection is realized. For the connected mode of traditional conducting strip through the tip centre gripping plug of parallel and level, the beneficial effect of this application embodiment includes:

on the one hand, the clamping force of the tooth-shaped part to the plug in the plugging and unplugging process is smaller, so that the friction loss of the plug to the conducting strip in the plugging and unplugging process is reduced, and the service life is prolonged.

On the other hand, each tooth part comprises a plurality of teeth, and each tooth forms an independent elastic conductive contact point which can be contacted with the plug more firmly. Meanwhile, the tooth parts of at least two conducting strips are overlapped, so that the contact area of the conducting strips and the plug is not reduced relative to the common conducting strips. Thereby ensuring the contact yield of the electrical connection. At the same time, the overlapping of the two teeth results in a more stable grip of the plug.

Furthermore, at least two conducting strips are respectively contacted with the plug through respective tooth parts, and when one conducting strip is in fault, the other conducting strip can still work normally. Therefore, the embodiment of the application reduces the insertion friction between the plug and the conducting strip under the condition of ensuring the contact yield, thereby reducing the use loss of the connecting terminal 20 and prolonging the service life of the connecting terminal 20.

It should be noted that, the number of the conductive sheets included in each group of the conductive assemblies 100 is not limited in the embodiments of the present application, and it can be understood that as the number of the conductive sheets increases, the electrical connection efficiency is higher, but the clamping force increases accordingly. Therefore, the number of conductive sheets in the conductive assembly 100 can be adjusted by those skilled in the art according to actual needs. For ease of understanding, the embodiments of the present application provide a preferred implementation as follows.

Referring to fig. 4, fig. 4 is an exploded view of a connection terminal in a connector with an improved connection terminal according to an embodiment of the present disclosure. As shown in fig. 4, the at least two conductive sheets include a first conductive sheet 110 and a second conductive sheet 120, wherein a first tooth 111 is formed at an end of the first conductive sheet 110, and a second tooth 121 is formed at an end of the second conductive sheet 120; the inner side of the first conductive sheet 110 is used for contacting with an electrical plug, and the second conductive sheet 120 is stacked outside the first conductive sheet 110; the second tooth 121 extends into the inside of the first conductive sheet 110 through the slot of the first tooth 111.

In this embodiment, each conductive assembly 100 includes a first conductive plate 110 and a second conductive plate 120 that are overlapped, and since the second tooth 121 located at the outer side passes through the tooth slot of the first tooth 111 and extends into the inner side of the first conductive plate 110, after the plug is inserted, the second tooth 121 is firstly contacted and pressed outwards, so as to ensure sufficient contact with the second tooth 121. And then contacts with the first dentate part 111, because the first dentate part 111 is positioned at the inner side, the plug can be fully contacted. Therefore, the first tooth-shaped part 111 and the second tooth-shaped part 121 are respectively in full contact with the plug, and the quality of electric connection is improved.

It should be noted that, as an alternative implementation manner, the tooth portion is provided as a tooth structure integrally formed on the conductive sheet, and the specific shape of each tooth on the tooth portion is not limited in the embodiments of the present application. For ease of understanding, a preferred implementation is provided below.

Referring to fig. 3 and 4, at least one of the first tooth 111 or the second tooth 121 has a bending portion bending toward the inner side of the first conductive sheet 110.

In this embodiment, the first tooth portion 111 or the second tooth portion 121 is bent in the following manner: the teeth of the first tooth portion 111 or the second tooth portion 121 are bent inward, thereby obtaining a bent portion. In the specific working process, the bending part can increase the pressure, and the connection quality is ensured by more fully contacting the plug. Meanwhile, the contact area of the tooth-shaped part and the plug is reduced, so that the friction is reduced. Optionally, the teeth of the first tooth portion 111 and the second tooth portion 121 each have a bent portion.

Further, the specific implementation manner that the second tooth portion 121 passes through the slot of the first tooth portion 111 and extends into the inner side of the first conductive sheet 110 is as follows: the bent portion of the second tooth portion 121 extends into the tooth slot of the first tooth portion 111.

While the specific implementation manners of the first conductive sheet 110 and the second conductive sheet 120 are described in detail above, it should be noted that, for the purpose of implementing conductivity, the material of each conductive sheet in the conductive assembly 100 is not limited in the embodiments of the present application. Preferably, the conductive sheet may be made of a material having both conductivity and wear resistance, such as highly conductive copper or copper-silver-titanium alloy. However, such a material is also determined to have insufficient elasticity, and may be deformed by being inserted and removed many times, so that the holding force for the plug cannot be secured. Therefore, to solve this problem, the following technical solutions are further adopted in the embodiments of the present application.

Referring to fig. 3 and 4, a support sheet 200 is disposed on the outer side of each conductive element 100, and optionally, the conductive sheet has higher conductivity and wear resistance than the support sheet 200, and the support sheet 200 has higher elasticity than the conductive sheet. The support sheet 200 elastically presses the conductive sheet.

In this embodiment, optionally, the supporting sheet 200 may be made of a stainless steel material, so that the elastic property of the supporting sheet 200 supports the conductive sheet to prevent the conductive sheet from being deformed due to insertion and extraction. The conducting strip contacts with the plug, so that the advantages of wear resistance and high conductivity are exerted. By the cooperative work of the support sheet 200 and the conductive sheet, the connection terminal 20 having wear resistance, high conductivity, and excellent elasticity is realized.

It should be noted that the support sheet 200 is configured to be located outside the conductive sheet, and for a specific implementation manner, the embodiment of the present application is not limited, and for convenience of understanding, a preferred implementation manner is provided below.

Referring to fig. 3 and 4, the support plate 200 has teeth 210 formed at its ends; the support sheet 200 is stacked on the conductive sheet, and the support teeth 210 abut against the teeth.

In this embodiment, the lower end of the supporting plate 200 is connected to the connector, and the upper end of the supporting plate 200 forms a supporting tooth 210, optionally, the supporting tooth 210 has the same shape as the tooth, and the supporting tooth 210 faces the tooth, so that the supporting tooth 210 supports the tooth to prevent the tooth from deforming during the insertion and extraction process. Alternatively, the support teeth 210 may support at least one of the first tooth 111 or the second tooth 121. Preferably, since the second tooth portion 121 extends into the first tooth portion 111 and is closer to the plug, and the first tooth portion 111 is disposed at the outer side and is more easily deformed away from the plug due to insertion and removal, the number of the supporting teeth 210 is the same as that of the first tooth portion 111, and each of the supporting teeth corresponds to one another, so as to support the first tooth portion 111 by the supporting teeth 210.

The connection terminal 20 improved in the embodiment of the present application is specifically described above, and the connection terminal 20 provided in the embodiment of the present application takes into account both the electrical connection quality and the service life, and the plugging frequency can be increased by more than one time compared with the conventional connection terminal 20. However, when the connection terminal 20 reaches the end of its service life, the entire connector has to be discarded, which causes higher costs in some industrial scenarios requiring high frequency plugging.

Therefore, to solve this problem, the embodiments of the present application further provide the following technical solutions.

Referring to fig. 2 and 5, fig. 5 is an exploded view of a connector with improved connection terminals according to an embodiment of the present disclosure. As shown in fig. 2 and 5, the connector is connected to the cable line 300, the end of the cable line 300 is provided with a cable connector 310 which is electrically conductive, and the connection terminal 20 is detachably connected to the cable connector 310.

In this embodiment, the cable connector 310 is optionally disposed inside the housing 10, and when the connection terminal 20 is connected to the cable connector 310, the circuit connection can be realized. Since the connection between the connection terminals 20 and the cable connector 310 is detachable, when one connection terminal 20 reaches the end of its service life, the connection terminal 20 can be detached from the cable connector 310, and the connection terminal 20 can be used again by replacing it with a new one. Thus, maintenance replacement can be achieved by only replacing a new connection terminal 20 at a time without replacing the entire connector, which greatly saves the use cost of the connector.

Alternatively, as to the detachable connection manner between the connection terminal 20 and the cable connector 310, the embodiment of the present application is not limited, and the connection terminal 20 may be directly connected to the cable connector 310, or the connection terminal 20 may be indirectly connected to the cable connector 310 through another component. For ease of understanding, a preferred implementation is provided below.

Referring to fig. 2 to 5, as shown in fig. 2 to 5, the connector further includes a copper bar 400, the connecting terminal 20 is detachably connected to the cable connector 310 through the copper bar 400, wherein the two conductive elements 100 are respectively connected to a first end of the copper bar 400 from two sides, and a second end of the copper bar 400 is detachably connected to the cable connector 310.

In this embodiment, optionally, the conductive member 100 and the supporting plate 200 are fixedly disposed at the first end of the copper bar 400, for example, are fixed by screwing. The second end of the copper bar 400 is detachably connected to the cable connector 310. Therefore, the connection between the conductive assembly 100 and the support plate 200 and the copper bar 400 is ensured to be stable, the contact area between the copper bar 400 and the cable connector 310 is relatively larger, and the electrical connection quality cannot be influenced due to detachable connection. Alternatively, the copper bar 400 and the cable connector 310 may be detachably connected by means of bolts.

It should be noted that, in order to determine whether the connection terminal 20 reaches the service life and detect the change of the current of the whole circuit, the following technical solutions are further adopted in the embodiment of the present application.

Referring to fig. 2 and 5, a temperature sensor 500 is further disposed in the housing 10, and the temperature sensor 500 is used for detecting the temperature of the connection terminal 20.

In this embodiment, optionally, a specific implementation manner of the temperature sensor 500 may be thermistor or thermocouple sensing, and the embodiment of this application is not limited thereto. Alternatively, the temperature sensor 500 is connected to an external data analysis unit, and the external data analysis unit determines whether the connection terminal 20 has reached the end of its life and whether an abnormality occurs in the operation of the connector, based on the temperature change fed back from the temperature sensor 500. Therefore, accurate and real-time judgment is realized.

The connector with the improved connecting terminal provided by the embodiment of the application has the advantages that the connecting terminal 20 has a better service life, on the basis, the connecting terminal 20 is replaceable relative to the connector, so that the use cost of the connector is further reduced, and further, the connector is also internally provided with the temperature sensor 500 for detecting the service life of the connecting terminal 20.

In this embodiment, the accommodating groove 13 is surrounded by the upper shell 11 and the lower shell 12, and when the connection terminal 20 needs to be replaced, the upper shell 11 only needs to be disassembled to be replaced. The upper shell 11 and the lower shell 12 may be detachably connected by a screw joint, a snap joint, or the like, and the embodiment of the present application is not limited thereto. In the accommodation groove 13, the temperature sensor 500 is brought into close proximity to or in contact with the connection terminal 20 so that the temperature of the connection terminal 20 can be detected more accurately.
