Referring to fig. 3, the present embodiment provides a connection terminal, which includes an insulating housing 10, the insulating housing 10 at least includes one wire inlet hole 11, each wire inlet hole 11 corresponds to a terminal pin 20, a pushing member 30, an elastic member 40 and a plurality of baffles 50, the terminal pin 20 and the elastic member 40 are installed inside the insulating housing 10, and the terminal pin 20 and the elastic member 40 are respectively located at two sides along a direction in which the wire inlet hole 11 extends, while the terminal pin 20 is in contact with the elastic member 40, the pushing member 30 is installed at a position in the insulating housing 10 adjacent to the wire inlet hole 40, so that the pushing member 30 can move to the inside of the insulating housing 10 along a direction parallel to the direction in which the wire inlet hole 11 extends at a position adjacent to the wire inlet hole 11, and further act on the elastic member 40, particularly, the plurality of baffles 50 are located at a side of the pushing member 30, and one end of the baffle 50 is fixed on the insulating housing 10, the other end is not lower than the end face of the pushing member 30, and a groove 31 is provided on the end face of the pushing member 30.

According to the wiring terminal provided by the embodiment, the plurality of baffles 50 are arranged on the side surface of the pushing element 30, and one end of each baffle 50 is not lower than the end surface of the pushing element 30, so that when a worker performs maintenance, the hand or tool of the worker may touch the pushing element 30 unintentionally and instead touch the baffle 50 on the outer side of the pushing element 30, and thus, the baffle 50 protects the pushing element 30, and further, the groove 31 is arranged on the end surface of the pushing element 30, and the groove 31 is recessed inwards, so that the probability that the hand or tool of the worker accidentally touches the pushing element 30 is further reduced, and thus, the wiring terminal avoids the phenomenon that the pushing element 30 accidentally touches the pushing element 30, and the phenomenon that the pushing element 30 accidentally pushes the elastic element 40, and thus the problem that the wire clamped between the elastic element 40 and the terminal pin 20 is loosened due to the elastic element 40 being accidentally pushed, and further, the normal use of the equipment is not influenced, and more importantly, the potential safety hazard and the like caused by the interruption of the electrical connection are eliminated.

It should be noted that, referring to fig. 3 to 5, the wire holes 11, the terminal pins 20, the elastic members 40, and the pushing members 30 in the wiring terminal are correspondingly arranged one by one to implement independent control of the wires in each wire hole 11, in this embodiment, each group of wire holes 11, terminal pins 20, elastic members 40, and pushing members 30 is referred to as a sub-wiring terminal 101, and a plurality of sub-wiring terminals 101 may be sequentially arranged.

Referring to fig. 3 and 4, in the present embodiment, it is preferable that the plurality of blocking plates 50 corresponding to each pushing member 30 include a first blocking plate 51 and a second blocking plate 52, the first blocking plate 51 is located on the side of the pushing member 30 away from the wire inlet hole 11, the second blocking plate 52 is located on the side adjacent to the side of the pushing member 30 away from the wire inlet hole 11, and the second blocking plate 52 is connected to the first blocking plate 51. When the connection terminal includes a plurality of sub-connection terminals 101, the second shutter 52 is located between the pressing members 30 of each sub-connection terminal 101 so as to make the pressing members 30 independent from each other, so that even if the number of the pressing members 30 is large, the pressing members 30 are not easily touched because the area formed by the end surfaces of the plurality of pressing members 30 is too large.

In this preferred embodiment, since the baffle 50 is disposed on each of three sides of the pushing element 30, the pushing element 30 is protected, and thus the baffle 50 can be omitted on the side of the pushing element 30 adjacent to the wire inlet 11 in consideration of reducing the processing cost and the processing difficulty.

In fact, when the wire releasing and taking actions are not performed, no force is applied between the pushing element 30 and the elastic element 40, and when the pushing element 30 pushes the elastic element 40, the pushing element 30 needs to move a certain distance to generate a force on the elastic element 40, in the prior art, in order to reserve the distance and facilitate manual operation, the pushing element 30 is usually higher than the end surface of the insulating housing 10, compared with the prior art, the baffle 50 of the wiring terminal in the embodiment structurally makes the pushing elements 30 compact, effectively utilizes the installation space, and when maintenance is performed, only when a tool (such as a screwdriver) is placed in the groove 31 of the pushing element 30, the pushing element 30 can be moved to play a role in preventing idle running, and not only the groove 31 and the compact pushing element 30 are designed, but also the whole size of the wiring terminal is reduced, the installation space is saved.

Referring to fig. 4, in order to further save the installation space, the size of the terminal may be reduced as much as possible without affecting the protection of the pushing member 30, for example, the end of the baffle 50 away from the insulating housing 10 may be flush with the end surface of the pushing member 30.

Referring to fig. 3, in order to reduce the number of processing steps and increase the strength of the baffle 50 during the processing, the baffle 50 may be integrally formed with the insulating housing 10, and preferably, a processing process in which the baffle 50 is integrally formed with the insulating housing 10 may be used.

In the present embodiment, the structure of the pushing element 30 can be in various forms, and the main functions thereof are: the end face of the pushing member 30 can be manually pressed by a worker or pressed by a tool, and one end of the pushing member 30 opposite to the end face can be moved to the elastic member 40 in the insulating housing 10 while pressing. With reference to fig. 6, in this regard, preferably, the structure of the pushing element 30 may be an L-shaped structure, wherein the L-shaped structure includes two parts perpendicular to each other, one part is a pressure receiving part 301 for pressing, an end surface of the pressure receiving part 301 is an end surface of the pushing element 30, the other part is an acting part 302 for acting on the elastic element 40, and an end of the acting part 302, that is, an end thereof far from the pressure receiving part 301, may act on the elastic element 40 in the insulating housing 10, such a structure of the pushing element 30 can achieve the function of the pushing element 30 and reduce the material consumed by the pushing element 30 as much as possible. In combination with the above-described arrangement in which the edge of the shutter 50 is flush with the end surface of the pushing member 30, the end surface of the pressure receiving portion 301 may be flush with the edge of the shutter 50.

Alternatively, referring to fig. 3 and 6, the end face of the pressure receiving portion 301 is rectangular, and correspondingly, a channel 12 with a rectangular cross section may be provided on the insulating housing 10 for the pushing member 30 to move in the insulating housing 10.

In this embodiment, when the pushing element 30 acts on the elastic element 40, the elastic element 40 will also provide a reaction force to the pushing element 30, because the pushing element 30 is provided with the baffle 50 only in three directions, and there is a high possibility that the pushing element 30 will incline under the action of the reaction force, thereby affecting the use of the pushing element 30, and in order to solve this problem, referring to fig. 7, an opening 111 may be provided on the hole wall of the wire feeding hole 11 adjacent to the pushing element 30, so that two guide rails 112 are formed on the hole wall on both sides of the opening 111, and the pushing element 30 can move along the guide rails 112, thereby the movement track of the pushing element 30 is limited, and the inclination phenomenon is avoided. In particular, based on the pushing element 30 having the L-shaped structure, the acting portion 301 of the pushing element 30 can move along the hole wall corresponding to both sides of the opening 111.

Of course, if necessary, the guide rail 112 may be formed on the hole wall on the opening 111 side, and the movement locus of the pushing member 30 may be limited as well. Therefore, it is conceivable that the number of the guide rails 112 is not particularly limited in the present embodiment, but there is at least one guide rail 112.

In order to ensure good contact of the wires after the wires are inserted into the connection terminal of the present embodiment and further ensure good connection between the devices, thereby reducing the number of processes such as maintenance, reconnection, and the like, referring to fig. 6, it is preferable that a through hole 32 is provided on the pushing member 30, the through hole 32 communicates the outside and the inside of the insulating housing 10, and the straight line of the through hole 32 intersects with the elastic member 40, and the through hole 32 is provided for testing the connection condition of the wires inserted into the connection terminal. The principle of the test is as follows: after the lead wire is clamped between the elastic member 40 and the terminal pin 20, a probe pin can be inserted into the through hole 32, the probe pin penetrates through the through hole 32 and extends to the elastic member 40 along the straight line of the through hole 32, at this time, the probe pin, the elastic member 40, the lead wire and the terminal pin 20 are connected, and if the elastic member 40 can conduct current signals and the like, the current signals and the like are communicated among the probe pin, the elastic member 40, the lead wire and the terminal pin 20, so that the lead wire is well connected as long as the probe pin can detect the current signals and the like. Wherein, the elastic member 40 can be a metal spring. The through hole 32 may be provided in the pressure receiving portion 301 in combination with the pressing tool 30 having the L-shaped structure.

When the operator operates the pushing member 30, the operation is usually performed by using a tool, and the size of the connecting terminal is small, so that the operation is inconvenient, and when the tool is placed in the groove 31 of the pushing member 30 for operation, the tool may slip, and the like, as shown in fig. 6, therefore, in the embodiment, the protrusion 311 is provided at the end of the groove 31 of the pushing member 30, so as to reduce the occurrence probability of the tool slipping, and the like. Preferably, a protrusion 311 may be provided at an end portion near the first shutter 51.

In this embodiment, the structure of the elastic member 40 can be various forms, and for the above-mentioned pushing member 30 with L-shaped structure, the structure of the corresponding elastic member 40 can also be various forms, for example, referring to fig. 8, the elastic member 40 can include a first fixing portion 41 and a clamping portion 42 connected, the first fixing portion 41 is fixedly installed inside the insulating housing 10, a free end 421 of the clamping portion 42 is in contact with the terminal pin 20, where the free end 421 refers to an end of the clamping portion 42 away from the first fixing portion 41, and an end of the acting portion 302 of the pushing member 30 can move onto the clamping portion 42, so that the free end 421 and the terminal pin 20 are loosened or separated.

Referring to fig. 8, based on the above-mentioned solution including the guide rail 112, while the pushing element 30 moves along the guide rail 112, the acted elastic element 40 also moves correspondingly, and in order to make the elastic element 40 move along the guide rail 112 in accordance with the movement of the pushing element 30, a limiting groove 422 matching with the guide rail 112 may be provided on the clamping portion 42 of the elastic element 40, and the limiting groove 422 is matched with the guide rail 112 and can move on the corresponding guide rail 112, and the clamping portion 42 can move in the opening 111.

There are various methods of achieving the contact of the elastic member 40 with the terminal pin 20, and the structure of the corresponding terminal pin 20 includes various methods.

Referring to fig. 3 and 9, the second fixing portion 21 includes a first limiting plate 211 and a second limiting plate 212 which are perpendicular to each other, the first limiting plate 211 and the second limiting plate 212 are not connected together, but a space is left for clamping the elastic member 40, so as to fix the elastic member 40 on the terminal pin 20, and specifically, the first fixing portion 41 of the elastic member 40 is clamped between the first limiting plate 211 and the second limiting plate 212; the second fixing portion 21 further includes a third limiting plate 213, the third limiting plate 213 is used to connect the first connecting plate 211, the second connecting plate 212 and the pin portion 22, meanwhile, the third limiting plate 213 is perpendicular to the first limiting plate 211, the third limiting plate 213 is also perpendicular to the second limiting plate 212, a limiting hole 2131 is provided on the third limiting plate 213, the limiting hole 2131 is used to fix the terminal pin 20 on the insulating housing 10, so as to avoid that the position of the terminal pin 20, which is affected by external force, changes, and the like in the operation process, correspondingly, refer to fig. 10, a limiter 13 matched with the limiting hole 2131 is installed inside the insulating housing 10, and the limiter 13 is correspondingly installed in the limiting hole 2131. Wherein, the stopper 13 can be a structure such as a buckle.

Referring to fig. 11, in order to facilitate the first fixing portion 41 of the elastic member 40 to be clamped between the first limiting plate 211 and the second limiting plate 212 without affecting the use of the clamping portion 42, it is preferable to provide a U-shaped connecting portion 43 between the first fixing portion 41 and the clamping portion 42, so that the first fixing portion 41 and the clamping portion 42 on both sides of the connecting portion 43 do not interfere with each other, and in combination with the pushing member 30 having the L-shaped structure, the acting portion 301 of the pushing member 30 can contact with the clamping portion 42 without generating an acting force when no wire is inserted, and the space between the pressure receiving portion 301 and the acting portion 302 can provide a moving distance for the pushing member 30, so that the acting portion 302 acts only on the clamping portion 42, thereby achieving the compact structure of the terminal and further reducing the overall size of the terminal. Moreover, when a test is performed using a probe pin, the probe pin can directly contact the connection portion 43, and the test operation is easily completed because the contact area is large.

Referring to fig. 9, the lead portion 22 contacts the free end 421 of the elastic member 40, and a wire can be inserted between the lead portion 22 and the free end 421 of the elastic member 40, preferably, in order to clamp the wire between the elastic member 40 and the lead portion 22 more firmly, the lead portion 22 is provided with a plurality of anti-slip grooves 221 for contacting the wire, so as to increase friction between the wire and the lead portion 22, the anti-slip grooves 221 and the wire insertion direction are at an inclined angle, preferably 45 °, which serves as an anti-slip function, and facilitates the wire insertion.
