Description

Technical Field

[0001] The utility model relates to a socket, specifically to an electrode terminal assembly of a European socket. Background Art

[0002] The shrapnel terminal has the advantage of convenient operation for disassembling and assembling wires. It is a common terminal in the existing market. It uses the elastic clamping force of the shrapnel to clamp and fix the wire. When in use, the wire is inserted and then pushes open the clamping position to achieve direct insertion and fixation of the wire. The shrapnel is also equipped with an operating component to drive the elastic clamping position to release the wire to complete the wire disassembly operation. However, the electrode terminal assembly on the existing European socket adopts a wire fixing structure of connecting a bolt and a nut block with an electrode socket. The wire is locked by screwing the bolt and the nut block, and there is no technology that combines the wire fixing structure of the shrapnel terminal with the electrode socket. As a result, the wire fixing method of the European socket is single. Therefore, how to combine the shrapnel wire fixing structure onto the electrode socket to realize the application of elastic clamping technology on the European socket is a topic that the applicant needs to study.

[0004] To achieve the above object, the utility model provides the following technical solutions:

[0005] An electrode terminal assembly of a European socket, comprising an electrode socket and a wire fixing terminal structure. The electrode socket includes two socket pieces arranged oppositely to form an insertion socket hole for the plug pin. It is characterized in that: the socket piece extends with a U-shaped connecting piece.

[0006] The wire fixing terminal structure includes a conductive frame. The conductive frame includes a bottom plate. The two lateral sides of the bottom plate turn upwards and extend with side plates. The two side plates are integrally formed and connected to one end of the U-shaped connecting piece in a one-to-one correspondence. The top end of the side plate turns inwards to form a curled ear. The ear groove of the curled ear constitutes a wire threading channel. A gap is formed between the two curled ears.

[0007] And a spring clip. The spring clip is arranged in the conductive frame. The spring clip includes a positioning part. The positioning part is fixed on the bottom plate. One end of the positioning part away from the electrode socket extends with a spring bow part. The spring bow part extends with a clip wire piece body that can swing elastically. The clip wire piece body extends obliquely towards the inside of the wire threading channel and along the wire perforation in the direction of insertion of the wire to be clamped. The free end of the clip wire piece body has a stop clip wire end corresponding in the wire threading channel, and a contact part for being touched to drive the elastic deformation of the clip wire piece body. The contact part corresponds to the gap position. The stop clip wire end and the wall of the wire threading channel cooperate correspondingly to form an elastic clip wire opening.

[0008] Preferably, a wire pressing elastic piece is folded and extended from the other end of the positioning part relative to the end connected to the spring bow part, and the wire pressing elastic piece extends obliquely in the inclined direction of the wire clamping elastic piece. The end of the wire pressing elastic piece is reversely turned and extended to form an arched wire clamping head, and the arc wall of the wire clamping head is correspondingly matched with the wall of the wire threading channel to form an inner wire clamping area.

[0009] Preferably, the middle of the wire pressing elastic piece is formed into two wire pressing elastic piece monomers respectively corresponding to two ear rings through a dividing groove, and the ends of the wire pressing elastic piece monomers both form the wire clamping heads.

[0010] Preferably, the top of the sheet body of the U-shaped connecting piece connected to the side plate is concave to form a notch, and the U-shaped connecting piece forms an avoidance space through the notch and forms a narrow connecting end connected to the side plate.

[0011] Preferably, the bottom edge of the U-shaped connecting piece is stamped inward to form a chuck guiding depression corresponding to the notch position, and the chuck guiding depression has a guiding inclined wall.

[0012] Preferably, a positioning hole is provided at the center of the positioning part, and a positioning convex point protrudes inward on the bottom plate, and the positioning convex point and the positioning hole are in positioning cooperation.

[0013] Preferably, windows are provided on the two side plates, a tongue plate is formed in the windows, the root of the tongue plate is connected to the bottom plate, and the tongue plate is folded inward to the inside of the conductive frame and presses against the positioning part.

[0014] Preferably, the top of the ear ring is arc-shaped.

[0015] By adopting the above technical solutions, an organic combination of a wire fixing terminal structure in the form of an electrode socket and an elastic clip is realized. The side plate of the conductive frame is integrally formed and connected to the socket piece of the electrode socket, and the socket piece and the conductive frame are connected by a U-shaped connecting piece to achieve a more compact structural arrangement. In addition, under the above connection, a wire threading channel for inserting a wire is formed at the top of the side plate of the conductive frame, and the contact part can be touched through the top direction of the conductive frame (i.e., the same as the orientation of the socket body) to press the wire clamping piece body, so as to complete the wire loosening operation, thereby facilitating the operation in the forward direction of the European socket to achieve the wire loosening operation; at the same time, the added wire pressing elastic piece, and the arched wire clamping head on the wire pressing elastic piece allows the direct plugging and unplugging operation of the wire, thereby ensuring the smoothness of the wire disassembly and assembly operation, and elastically clamping and fixing the inner side of the inserted wire again.

Specific embodiments

[0023] See the attached Figures 1 - 5 As shown in the figure, a European-style socket electrode terminal assembly disclosed by the present utility model includes an electrode socket 1 and a wire fixing terminal structure; the electrode socket 1 includes two socket pieces 11 arranged oppositely to form a socket hole for inserting a plug foot, and the socket piece 11 extends with a U-shaped connecting piece 12, that is, the socket piece 11 is located between the two side pieces of the two U-shaped connecting pieces 12. The wire fixing terminal structure includes a conductive frame 2. The conductive frame 2 includes a bottom plate 21. The two lateral sides of the bottom plate 21 are turned upwards and extended with side plates 22. The two side plates 22 are integrally formed and connected to one end of the U-shaped connecting piece 21 in a one-to-one correspondence. In this way, the integral molding connection of the wire fixing terminal structure and the electrode socket 1 is realized, ensuring the electrical conductivity. Using the two side plates to extend to form the U-shaped connecting piece 12 is more convenient and reliable in molding, and the structure is also compact. The top ends of the side plates 22 are turned inwards to form curling ears 23. The ear grooves of the curling ears 23 constitute a wire threading channel 231 to realize the guiding insertion of the wire, and a gap is formed between the two curling ears 23.

[0024] A spring clip 3 is provided in the conductive frame 2. The spring clip 3 includes a positioning portion 31 which is fixed on the bottom plate 21. One end of the positioning portion 31 away from the electrode socket 1 extends with a spring bow portion 32. The spring bow portion 32 extends with a wire clamping piece body 33 which can elastically swing. The wire clamping piece body 33 faces towards the wire threading channel 231 and extends obliquely along the wire perforation in the insertion direction of the wire to be clamped. The free end of the wire clamping piece body 33 has a backstop wire clamping end 331 corresponding in the wire threading channel 231, and a contact portion 332 for being touched and pressed to drive the elastic deformation of the wire clamping piece body 33. The contact portion 332 corresponds to the interval position. The backstop wire clamping end 331 and the wall of the wire threading channel 231 cooperate correspondingly to form an elastic wire clamping opening. In this way, when the wire is inserted into the wire threading channel 231, the wire clamping piece body 33 can be pushed to deform to enter the elastic wire clamping opening. The free end of the wire clamping piece body 33 corresponds to the upper side. The backstop wire clamping end 331 and the contact portion 332 are formed on the free end. The contact portion can be touched and pressed by touching from the top direction of the conductive frame (i.e., consistent with the orientation of the socket body) to press the wire clamping piece body, so as to complete the wire loosening operation, thereby facilitating the operation in the forward direction of the European socket to achieve the wire loosening operation. The top of the ear 23 is arc-shaped; this facilitates the more smooth insertion and extraction operation of the wire. And under the arc-shaped design, the occupied volume is small and the structure is more compact.

[0025] To better realize the forming connection between the U-shaped connecting piece 12 and the side plate 22, the top of the piece body of the U-shaped connecting piece 12 connected to the side plate 22 is recessed to form a notch 121. The U-shaped connecting piece 12 forms an avoidance space through the notch 121 and forms a narrow connecting end connected to the side plate 22. In this way, while ensuring the height dimension of the socket, reliable connection with the side plate 22 can be realized, avoiding the excessive height of the side plate 22 and making the structure more compact. During installation and use, the notch 121 can also be further utilized, such as cooperating with a chuck to realize snap fixation. On the other hand, it can provide position avoidance and provide space for the design of other structures, such as the limiting structure for the end position of the wire inserted into the wire threading channel.

[0026] To better realize the snap fixation and cooperation of the chuck at the notch position, the bottom edge of the U-shaped connecting piece 12 is stamped inward to form a chuck guiding depression 122 corresponding to the notch 121 position. The chuck guiding depression has a guiding inclined wall 1221. In this way, the chuck can be guided to deform through the guiding inclined wall to be better clamped to the wall of the notch.

[0027] At the same time, a chuck 221 is provided on the side plate 22 to cooperate with the corresponding structure on the groove wall of the housing for its installation.

[0028] As another embodiment of the present utility model, a wire pressing elastic piece 34 is folded and extended at the other end of the positioning portion 31 relative to the end connected to the spring bow portion 32. The wire pressing elastic piece 34 extends obliquely in the inclined direction of the wire clamping elastic piece 33, so as to facilitate the insertion of the wire to push the wire pressing elastic piece 34 to deform. The end of the wire pressing elastic piece 34 is reversely flipped and extended to form an arched wire clamping head 341. The arc wall of the wire clamping head 341 cooperates with the wall of the wire threading channel 231 to form an inner wire clamping area. In this way, two-point clamping of the wire is realized in the wire insertion direction, making the clamping and fixing of the wire more reliable, and also providing a position for the wire clamping and electrical connection. While the wire is fixed reliably, the electrical connection points are increased. The wire has reliable fixing and electrical connection. At the same time, due to multi-point fixing along the wire insertion direction, the deep insertion design of the wire can be realized, ensuring reliable wiring. The middle of the wire pressing elastic piece 34 is formed into two wire pressing elastic piece monomers corresponding to the two coil ears 23 respectively through a dividing groove, and the ends of the wire pressing elastic piece monomers both form the wire clamping head 341. Bilateral wire fixing is realized.

[0029] As another embodiment of the present utility model, a positioning hole 311 is provided at the center of the positioning portion 31, and a positioning bump 211 protrudes inward on the bottom plate 21. The positioning bump 211 and the positioning hole 311 are in positioning cooperation to realize the central positioning of the positioning portion 31, prevent the positioning portion 31 from moving on the bottom plate 21, and the positioning structure is simple and easy to process.

[0030] Windows 222 are provided on the two side plates 22. A tongue plate 223 is formed in the windows 222. The root of the tongue plate 223 is connected to the bottom plate 21. After the tongue plate 223 is folded inward into the conductive frame, it presses against the positioning portion 31. The tongue plate presses both sides of the positioning to realize positioning.

[0031] The present utility model provides a combination solution of an electrode socket and a terminal structure in the form of an elastic piece, realizing an elastic clamping and fixing method for wires on a socket, making the wiring operation of the socket more convenient.
