[0002] The front insertion type quick socket plays a vital role on the switch cabinet, which is mainly used for connecting the incoming and outgoing line bushings of the switch cabinet and the wall bushing and double-through bushing of the cable branch box, ensuring the full insulation and full sealing connection between the power cable and the switch cabinet or the cable branch box.

[0003] Meanwhile, the existing front insertion type quick socket is generally connected to the bushing socket of the switch cabinet through bolts, and its tail can be directly plugged with an insulating plug, or it can be extended to connect a rear insertion type cable plug or a rear insertion type lightning arrester. By involving the insulating plug or the lightning arrester, the safety and protection capability of the switch cabinet can be further enhanced. By involving the rear insertion type cable plug, the number of the rear insertion type cable plugs can be multiple, i.e., only one incoming and one outgoing can be achieved without involving the rear insertion type cable plug, while similar to one incoming and several outgoing can be achieved after involving the rear insertion type cable plug.

The inside of the connecting bushing and the inside of the quick plug base are penetrated by a conductive sleeve, one end of which extends to the direction of the quick plug plug, i.e., when the front insertion type quick socket is not connected to the cable branch box, the quick plug plug is plugged to play the required safety protection role. The other end of the conductive sleeve is connected to a terminal, and the terminal is similar to a terminal nose structure. In addition, the terminal nose is located in the front insertion rubber sleeve. Thus, when the incoming and outgoing line bushings of the switch cabinet are inserted into the front insertion rubber sleeve, the conductive terminals on the incoming and outgoing line bushings are inserted into the terminal nose and connected through bolts, and the conductive sleeve is limited by a pin.

[0022] As Figures 1-8The utility model discloses a front insertion type quick socket, including the mutual contact of quick plug base 2 and connecting sleeve 3, the inside of quick plug base 2 and the inside of connecting sleeve 3 are penetrated respectively to the front insertion rubber sleeve 64, the quick plug plug that is distributed on quick plug base 2 forms the safety protection, and the front insertion rubber sleeve 64 is connected to the direction of the one end of quick plug plug that extends, the other end of front insertion rubber sleeve 64 is provided with terminal 5, and the terminal 5 is inserted into the front insertion rubber sleeve 64 relative to the one end of front insertion rubber sleeve 64, and forms the installation position 52 that the conductive terminal of the incoming and outgoing line sleeve of external switch cabinet extends, and the sleeve wall 42 of front insertion rubber sleeve 64 is provided with one or more clamping point grooves 41, and the terminal 5 is formed with the protruding 51 that is adapted with clamping point groove 41;

[0023] And the sleeve wall 42 of front insertion rubber sleeve 64 is limited to the sleeve wall 42 of front insertion rubber sleeve 64, and the other end extends towards the direction of the sleeve wall 42 of front insertion rubber sleeve 64, and the terminal 5 is inserted into the front insertion rubber sleeve 64, and the protruding 51 is clamped into the clamping point groove 41, and the elastic clamping action of the clamping spring 7 on the outer surface of the terminal 5, and the installation limit of the terminal 5 in the front insertion rubber sleeve 64.

[0024] The above-mentioned front insertion rubber sleeve 64 and terminal 5 are clamped and limited by the cooperation of clamping point groove 41 and protruding 51, and the clamping spring 7 in the front insertion rubber sleeve 64, so that the terminal 5 is in contact with the clamping spring 7 on the sleeve wall 42 of the front insertion rubber sleeve 64 during insertion into the front insertion rubber sleeve 64, that is, as the terminal 5 is continuously inserted into the front insertion rubber sleeve 64, the clamping spring 7 moves towards the sleeve wall 42 of the front insertion rubber sleeve 64, so that after the terminal 5 is inserted into the front insertion rubber sleeve 64, the clamping spring 7 is in contact with the outer surface of the terminal 5, and the front insertion rubber sleeve 64 and the terminal 5 are limited by the cooperation of clamping point groove 41 and protruding 51, and the contact of the clamping spring 7, which replaces the existing screwing method and greatly simplifies the production and assembly process of the front insertion rubber sleeve 64 and the terminal 5.

[0025] As Figures 1-3, 5, 6, the mating recess 31 is arranged on the connecting sleeve 3 relative to the region in contact with the quick plug base 2, the mating protrusion 21 is arranged on the quick plug base 2 relative to the region in contact with the connecting sleeve 3, the mating recess 31 and the mating protrusion 21 are matched to form the guide of the contact matching position between the quick plug base 2 and the connecting sleeve 3, and constitute the opposite distribution between the quick plug base 2 and the connecting sleeve 3; the fastener setting hole is arranged on the mating recess 31, the fastener setting matching hole is arranged on the mating protrusion 21, the fastener setting hole and the fastener setting matching hole are distributed on the same straight line, the mating protrusion 21 and the mating recess 31 are matched, the fastener setting hole and the fastener setting matching hole are arranged in position, and the installation limiting of the quick plug base 2 and the connecting sleeve 3 is formed through the limiting of the fastener; in the above scheme, the mating protrusion 21 is embedded in the mating recess 31, that is, during the matching process of the connecting sleeve 3 and the quick plug base 2, the connecting sleeve 3 and the quick plug base 2 can be reliably positioned, and then fastened by the fastener, and the connecting sleeve 3 and the quick plug base 2 can be accurately positioned through the mating recess 31 and the mating protrusion 21, avoiding the situation that due to the limit of the existing part, the shape tolerance is in the limit value stage during the subsequent matching process, causing the insertion of the front plug rubber sleeve 64.

[0026] As Figures 1-4 , 6-8, the through region extending from one side of the circumferential surface to the other side of the circumferential surface is arranged on the circumferential surface of the terminal 5, the protrusion 51 is formed in the card-in stage of the card point groove 41 through the through region, the protrusion 51 on the terminal 5 slightly moves inward in the direction of the through region, the preferred design of the through region is the through hole 53 extending from the position of the axis of the terminal on one side of the circumferential surface to the other side, which can make the protrusion 51 on the terminal 5 slightly move inward when the protrusion 51 and the card point groove 41 are matched, that is, when the two are matched, the protrusion 51 on the terminal 5 can move inward to a certain extent in the direction of the waist-shaped hole, so that the matching between the protrusion 51 and the card point groove 41 is more convenient, and the situation that the metal is not easy to be inserted into the metal is avoided; the preferred design of the through hole 53 is a waist-shaped hole, which can avoid the situation that the protrusion 51 slightly moves inward during the card-in process of the protrusion 51 and the card point groove 41, and the stress concentration caused by the excessively protruding corner may affect the strength of the terminal 5.

[0027] As Figures 4-7As shown, a guide portion 54 is provided on the front insert sleeve 64 in the insertion direction relative to the terminal 5. The protrusion 51 on the terminal 5 is designed to pass through the guide portion 54. This avoids the problem of the protrusion 51 on the terminal 5 not being of suitable height, which would affect the insertion into the front insert sleeve 64 and the fit with the locking slot 41, and also ensures the rationality of the design.

[0028] like Figures 4-5 As shown in Figures 7-8, the multiple locking slots 41 and the protrusions 51 on the terminal 5 are arranged in close proximity. The multiple locking slots 41, the protrusions 51, the protrusions 51 and the terminal 5, and the locking slots 41 and the sleeve wall 42 of the front insert sleeve 64 are all provided with arc-shaped angles. This design allows for a more secure fit between the terminal 5 and the front insert sleeve 64 through the interaction of the multiple locking slots 41 and the protrusions 51. The preferred solution is to have only two slots 41 and two protrusions 51. This avoids the problem of too many slots affecting assembly, which could make assembly difficult. In addition, the arc-shaped corner design further ensures that the terminal block 5 and the front insert sleeve 64 will not be difficult to insert or remove due to the angle or top angle, or that the outer surface of the terminal block 5 or the sleeve wall 42 of the front insert sleeve 64 will be scratched during the insertion or removal process.
