[0043] Reference Figure 1As shown, it discloses a socket for a relay according to an embodiment of the utility model. The socket for a relay includes a mounting housing 10 and an ejection assembly 20, a terminal assembly, a circuit board assembly 50 and a lighting assembly 60 arranged inside the mounting housing 10. In order to accommodate and install the above-mentioned several electrical components, the mounting housing 10 is provided with an installation chamber. Considering the convenience of operation, the ejection assembly 20 is arranged at one end of the mounting housing 10 to facilitate driving the relay a to complete the ejection action.
[0044] Figure 2 This is a schematic cross-sectional structure diagram of a relay socket according to an embodiment of the present utility model. Figure 1 as well as Figure 2 As shown, considering the operability of electrical connection, the terminal assembly of the utility model includes an input terminal unit 30 and an output terminal unit 40. The input terminal unit 30 includes a first input terminal 31 and a second input terminal 32, and the first input terminal 31 and the second input terminal 32 are both arranged on one side of the mounting housing 10. The output terminal unit 40 includes a first output terminal 41, a second output terminal 42 and a third output terminal 43, and the first output terminal 41, the second output terminal 42 and the third output terminal 43 are all arranged on the other side of the mounting housing 10.
[0045] like Figure 2 and Figure 4 As shown, the circuit board assembly 50 is accommodated in the installation chamber of the installation housing 10 and is close to the input terminal unit 30. The lighting assembly 60 is arranged in the installation chamber of the installation housing 10 adjacent to the circuit board assembly 50, and includes a light-emitting member 61 and a light-guiding channel 62. The light-emitting member 61 is arranged at one end of the circuit board assembly 50. The light-guiding channel 62 is connected to the light-emitting head of the light-emitting member 61 and extends toward the outer surface of the installation housing 10.
[0046] It is worth pointing out that referring to Figure 2 and Figure 3As shown, the ejection assembly 20 of the utility model includes an operating handle 21, a driving part 22 and an ejection part 23. Exemplarily, the operating handle 21 has a movable end and a connecting end 212, and the connecting end 212 is used to connect to the mounting housing 10. One end 221 of the driving part 22 abuts against the connecting end 212 of the operating handle 21. Specifically, the driving part 22 and the operating handle 21 are connected in a contact connection manner, that is, the connecting end 212 of the operating handle 21 transmits the driving force toward the end 221 of the driving part 22 by surface contact. The ejection part 23 extends vertically to the side along the end of the driving part 22 and is pivotally connected to a predetermined position of the mounting housing 10. The relay a is accommodated in a accommodating chamber formed by the operating handle 21, the driving part 22 and the ejection part 23. The ejection part 23 pushes the relay a to move by the ejection contact surface 231 set at its end, which can better protect the protective shell of the relay a and increase the reliability of the drive. By adopting the above-mentioned design of the ejection assembly of the utility model, the force arm of the ejection part 23 is further increased, so the operating force of the ejection action can be effectively reduced, and the wear on the outer wall of the relay a can be reduced, so its mechanical service life can be increased.
[0047] According to a preferred embodiment of the utility model, a sheet hinge 24 with a predetermined elasticity is formed between the driving part 22 and the ejection part 23, and a preset chamber 241 is also formed in the middle of the sheet hinge 24, so as to realize the automatic reset after the deformation of the driving part 22 under the action of elastic force after the driving displacement occurs, thereby avoiding the generation of reverse force on the relay. In an optional implementation, exemplarily, the driving part 22, the ejection part 23 and the sheet hinge 24 adopt an integrated elastic rod structure with a roughly L-shaped layout.
[0048] Reference Figure 3 It is worth pointing out that the pivot point p of the ejector 23 connected to the mounting housing 10 maintains a predetermined straight-line distance d from the axis of the driving part 22, and the range of the straight-line distance d is about 5mm to 7mm. It can be understood that in different embodiments, the value of the straight-line distance d selected by those skilled in the art according to the actual design requirements of the product is not unique. For example, the straight-line distance d can be any value between 5mm to 6mm, 5.5mm to 6.5mm or 6mm to 7mm, etc., and these specific values are within the above protection scope of the present utility model. Through the above structural design, since the pivot point p of the ejector 23 maintains the above predetermined straight-line distance d from the axis of the driving part 22, the driving force arm of the ejector 23 can be effectively increased, and the ejection force can be effectively reduced by increasing the force arm, thereby enhancing the efficiency of the drive and ensuring the reliability of the drive.
[0049] Furthermore, in order to achieve a more stable and reliable positioning effect, the movable end of the operating handle 21 of the utility model is provided with a snap portion 211, and a snap-in groove 101 is provided at the corresponding position of the mounting shell 10. The operating handle 21 is arranged straightly at a position located at the top of the relay a, and can completely cover the relay a on the inner side of the operating handle 21 to better protect the relay.
[0050] In an optional implementation, the light emitting element 61 is an LED light source, which is fixed to the circuit board assembly 50 by a patch connection method. The patch fixing method can achieve a more secure positioning effect, effectively save the internal space of the socket, and further optimize the installation steps.
[0051] like Figure 4 As shown, in an optional implementation, the light guiding channel 62 is a vertical light guiding strip extending outward along the light scattering direction of the LED light source. Since the light transmission loss is small, a better light guiding effect can be achieved.
[0052] In an optional implementation, a lighting indication module 12 is also provided on the mounting shell 10, and the lighting indication module 12 is adjacent to the operating handle 21. The lighting indication module 12 has a lighting display window 120, which is flush with the outer surface of the mounting shell 10, and the end of the light guide channel 62 is connected to the lighting display window 120.
[0053] The lighting indication module 12 is embedded in the corner of the mounting shell 10. In this implementation, the lighting display window 120 includes a first lighting display window 121 embedded on the top wall of the mounting shell 10, and a second lighting display window 122 embedded on the side wall of the mounting shell 10. Through the above design, the light-emitting area of the outer wall of the relay socket is larger, and the visible range and angle of light are wider, which effectively improves the user's operating experience.
[0054] To sum up, the socket for relay of the utility model has better structural reliability and more stable and efficient driving effect. At the same time, due to the more ingenious design of the light guide channel and the light source, the light guide efficiency is greatly improved, and the luminous indication area of the outer wall is larger, which effectively improves the operational convenience during user use.
