Description

Technical Field

[0001] The utility model relates to the technical field of relay sockets, in particular to a retaining spring for a relay socket and a relay socket. Background Art

[0002] As attached Figure 4 As shown, an existing relay socket is provided with a spring clip 1' for pressing and fixing the relay 3' at the relay assembly position of the relay socket 2'. Specifically, the spring clip 1' is a lever structure, and the spring clip 1' is rotatably connected to the relay socket 2' through a rotating shaft structure. The spring clip 1' takes the rotating shaft position as a rotation fulcrum and has a first lever end and a second lever end opposite to each other. The first lever end is formed with a snap-fitting portion 12' for snapping and positioning with a snap on the relay socket, and the second lever end is provided with an elastic pressing portion 11' for elastically pressing the top of the relay to press and fix the relay on the relay socket. However, in this technical solution, since the elastic pressing portion 11' directly acts on the top position of the relay 3', when the size of the spring clip 1' is fixed, the applicable height size of the relay 3' is limited to a certain range (i.e., within the elastic pressing action range of the elastic pressing portion), and it cannot adapt to relays exceeding the applicable height, that is, the applicable range of the relay socket is limited, and the universal adaptability to relays of different height sizes is poor, and there are limitations in use. Utility Model Content

[0003] In view of the deficiencies of the prior art, the utility model provides a retaining spring for a relay socket, which mainly solves the technical problem that the prior relay socket has poor universal adaptability to relays of different heights and sizes.

[0004] In order to achieve the above object, the utility model is realized by the following technical solutions:

[0005] A retaining spring for a relay socket comprises a main body, on which is formed a rotating connection portion for movably connecting with the relay socket, the main body takes the rotating connection portion as a rotation fulcrum and is formed with a first lever end and a second lever end arranged opposite to each other, the first lever end is formed with a clamping portion for cooperating with a buckle on the relay socket, the second lever end is formed with a stopper, and when the clamping portion forms a buckle fit with the buckle, the stopper is configured to form a pressure limit fit with a protrusion preset on the side of the relay to press and fix the relay at the relay assembly position of the relay socket.

[0006] Furthermore, the stopper comprises an elastic support arm vertically connected to the second lever end and a stopper connected to the bottom of the elastic support arm for pressing against a protrusion on the side of the relay.

[0007] Furthermore, the main body includes two side panels arranged opposite to each other on the left and right, and the spacing between the two side panels is adapted to the width dimension of the relay so that the relay can be correspondingly embedded in the spacing space between the two side panels, and a cross-connecting push rod for lifting the relay from the relay assembly position of the relay socket is provided on the first lever end of the main body, and a pulling operating part connected between the two side panels is provided on the second lever end of the main body.

[0008] Furthermore, two elastic support arms are provided at the bottom of the pull operating part, which are close to the two side plates respectively. A stopper is provided at the bottom of each elastic support arm, and avoidance gaps corresponding to the stoppers are opened on the two side plates. The side ends of the stoppers at the bottom of the two elastic support arms extend laterally into the avoidance gaps of the side plates on the corresponding sides.

[0009] Furthermore, anti-slip teeth are formed on the pull operation part.

[0010] Furthermore, the rotating connection portion is a rotating shaft mounting hole structure opened on the side plate.

[0011] Based on the same inventive concept, the utility model also provides a relay socket, including any of the above-mentioned retaining springs for the relay socket.

[0012] The above technical solution has the following advantages or beneficial effects:

[0013] In the retaining spring and relay socket for the relay socket described in the utility model, a stopper is provided on the main body of the retaining spring, and the stopper is configured to press against the protrusion on the side of the relay. Compared with the technical solution of the existing retaining spring that uses the elastic pressing part to press against the top of the relay, the stopper of the retaining spring acts on the protrusion preset on the side of the relay. Therefore, as long as a protrusion structure that can cooperate with the stopper is preset at the corresponding height position of the relay, the relay can be pressed and fixed at the relay assembly position of the relay socket by utilizing the mutual cooperation between the stopper and the protrusion, and there is no need to consider the height size of the relay, which is conducive to the relay socket equipped with the retaining spring to adapt to more relays of different height sizes.

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0022] Please refer to the attached Figure 1 To Attachment Figure 3 An embodiment of the utility model provides a retaining spring for a relay socket, comprising a main body 1, on which is formed a rotating connection portion 111 for movably connecting with the relay socket 2, the main body 1 takes the rotating connection portion 111 as a rotation fulcrum and is formed with a first lever end and a second lever end arranged oppositely, the first lever end is formed with a clamping portion 15 for cooperating with a buckle 21 on the relay socket 2, and a stopper 14 is formed on the second lever end, and when the clamping portion 15 forms a buckle fit with the buckle 21, the stopper 14 is configured to form a pressure-limiting fit with a protrusion 31 preset on the side of the relay 3 to press and fix the relay 3 at the relay assembly position of the relay socket 2. It can be understood that in the present embodiment, a stopper 14 is provided on the main body 1 of the retaining spring, and the stopper 14 is configured to press against the protrusion 31 on the side of the relay 3. Compared with the technical solution of the existing retaining spring using an elastic pressing portion to press against the top of the relay, the stopper 14 of the retaining spring acts on the protrusion 31 preset on the side (rear side) of the relay 3. Therefore, as long as a protrusion 31 structure that can cooperate with the stopper 14 is preset at the corresponding height position of the relay 3, the relay 3 can be pressed and fixed at the relay assembly position of the relay socket 2 by utilizing the mutual cooperation between the stopper 14 and the protrusion 31, and there is no need to consider the height size of the relay 3, which is conducive to the relay socket 2 equipped with the retaining spring to adapt to more relays 3 of different height sizes.

[0023] Please refer to the attached Figure 1 To Attachment Figure 3 In one preferred embodiment, the stopper 14 includes an elastic support arm 141 vertically connected to the second lever end and a stopper 142 connected to the bottom of the elastic support arm 141 for pressing the protrusion 31 on the side of the relay 3. In this embodiment, the elastic support arm 141 can be bent and deformed, so that the stopper 142 can be elastically pressed against the protrusion 31 on the side of the relay 3. In this way, even if the protrusion 31 on the side of the relay 3 has a certain deviation in specific height due to processing accuracy problems, the elastic force generated by the front and rear bending deformation of the elastic support arm 141 allows the stopper 142 to be elastically pressed against the protrusion 31 on the side of the relay 3, thereby ensuring that the relay 3 is firmly connected to the relay assembly position of the relay socket 2.

[0024] Please refer to the attached Figure 1 To Attachment Figure 3 In one preferred embodiment, the main body 1 includes two side panels 11 arranged opposite to each other, the spacing between the two side panels 11 is adapted to the width of the relay 3, so that the relay 3 can be correspondingly embedded in the spacing space between the two side panels 11, and the first lever end of the main body 1 is provided with a cross-connecting push rod 12 for lifting the relay 3 from the relay assembly position of the relay socket 2, and the second lever end of the main body 1 is provided with a pull operation part 13 connected between the two side panels 11. It can be understood that in this embodiment, the left and right side directions of the relay 3 installed on the relay socket 2 can be limited by the mutual cooperation of the two side panels 11.

[0025] Please refer to the attached Figure 1 To Attachment Figure 3In one preferred embodiment, two elastic support arms 141 are provided at the bottom of the pull operation part 13, and are close to the two side plates 11 respectively. A stopper 142 is provided at the bottom of each of the two elastic support arms 141, and a relief notch 112 corresponding to the stopper 142 is provided on each of the two side plates 11. The side ends of the stopper 142 at the bottom of the two elastic support arms 141 extend into the relief notch 112 of the side plate 11 on the corresponding side. In this way, when the elastic support arm 141 swings and bends forward and backward, the relief notch 112 is relieved by the action of the stopper 142, so that the stopper 142 can better press against the protrusion 31 on the side of the relay 3. More importantly, the avoidance gap 112 can also be used to limit the movement range of the block 142, so that the stopper 14 can not only cooperate with the protrusion 31 to press and fix the relay 3 at the relay assembly position of the relay socket 2, but also, by limiting the movement range of the block 142 by the avoidance gap 112, the stopper 14 itself can correspond to the rear side of the relay 3, and then when the relay 3 swings back and forth relative to the relay socket 2, the rear direction of the relay 3 can be effectively limited, thereby greatly improving the assembly stability of the relay 3 and the relay socket 2, so that it can be better used in high-vibration environments such as rail transit, wind power, and industrial control.

[0026] Please refer to the attached Figure 1 To Attachment Figure 3 In one preferred embodiment, an anti-slip tooth pattern 131 is formed on the pull operation portion 13.

[0027] Please refer to the attached Figure 1 To Attachment Figure 3 In one preferred embodiment, the rotating connection portion 111 is a rotating shaft mounting hole structure opened on the side plate 11.

[0028] Please refer to the attached Figure 1 To Attachment Figure 3 An embodiment of the utility model further provides a relay socket, including the relay socket of any of the above embodiments.

Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some of the technical features therein with equivalents.
