Small-power multi-core socket device

Technical field

The utility model is related to socket devices, and in particular, to a kind of small-power multi-core socket device.

Background technology

Signal connector used in the small-power encoder for servo motor of existing market is mostly 7 core signal connectors, structure It is inserted into plastic shell after pressing line for crimping terminal, is tangled using the elastic arm on the hook and plastic shell on terminal solid Determine, as shown in Figure 1, this signal connector requires height to terminal crimping, crimping is bad to be influenced outside contact and terminal and plastics The fixation of shell, in addition the fixed form of socket and motor is the structure of interference fit, the problem of because of product tolerance, will produce socket The risk taken off from motor.

The quality problem of signal connector socket, existing market are used on existing market on small-power encoder for servo motor The 7 core socket of signal used has following three：

1：The fixed structure of jack body and motor is the mode of interference fit, by several muscle and electricity on jack body The close-fitting of machine trepanning is fixed, and there are insecure risks, now have existed the problem of socket falls off from motor.

2：Terminal is same as the fixed form of plastic shell unstable, and structure is on hook and plastic shell on terminal The elastic arm of force tangle, there are the failure of the elastic arm of force, reset it is bad lose control of one's feelings needle the case where, in addition also have to terminal crimping higher It is required that as shape crimping is bad, also influences terminal and whether to be in place inserted into, to the more demanding of worker's insertion terminal, such as terminal assembles It is not in place equally to will produce the case where terminal is lost control of one's feelings.

3：Terminal is the structure of 0.2mm plate stampings, and contact area is the mode of two panels superposition, and the tolerance of thickness is larger, Larger to the plug fluctuation of contact, the intensity of terminal is poor, in use by external impacts when be easy crooked, lose Function.

According to a kind of small-power multi-core socket device provided by the utility model, including jack housing and multiple socket ends Son, the jack housing bottom have extended downwardly protrusion；Multiple female terminal one end are coated in the jack housing, another End is pierced by from the protrusion lower surface；The top of the jack housing is provided with multiple connecting holes, and the connecting hole extends to One end of the female terminal.

Preferably, further include screw, the corner of the jack housing is provided with screw through-hole, and the screw is logical by screw Hole and the bottom surface for being pierced by the jack housing.

Preferably, upwardly extend the interconnecting piece for being useful for connection plug at the top of the jack housing, the interconnecting piece it is outer Enclose it is circumferentially arranged have a groove, the first sealing ring is provided in the groove.

Preferably, further include the second sealing ring, second sealing ring is placed on the protrusion and the jack housing bottom The junction in portion.

Preferably, 7 female terminals are coated in the jack housing, 7 female terminals are divided into two rows of settings.

Preferably, the screw bottom is less than at a distance from jack housing bottom outside the female terminal other end and socket The distance of shell bottom.

Compared with prior art, the utility model has following advantageous effect：

1, the utility model by the assembling mode of jack housing and female terminal, it can be achieved that Automated assembly, improves The process efficiency of assembling, reduces product cost；

2, female terminal is directly fixed on outside socket by the utility model using the connection type of jack housing connection motor In shell, the requirement to female terminal crimping is reduced, reduces damage of the female terminal in external impacts.

Specific implementation mode

The utility model is described in detail with reference to specific embodiment.Following embodiment will be helpful to this field Technical staff further understands the utility model, but does not limit the utility model in any form.It should be pointed out that ability For the those of ordinary skill in domain, without departing from the concept of the premise utility, several changes and improvements can also be made. These belong to the scope of protection of the utility model.

As shown in Figures 2 to 4, according to a kind of preferred implementation of small-power multi-core socket device provided by the utility model Example, including the first sealing ring 1, screw 2, jack housing 3, female terminal 4 and the second sealing ring 5, the jack housing 3 are in square The bottom of shape structure, jack housing 3 has extended downwardly protrusion, and the protrusion and the junction of the jack housing bottom cover Equipped with the second sealing ring 5, the second sealing ring 5 is used to ensure leakproofness when small-power multi-core socket device is connected with motor；It inserts 3 top of seat shell upwardly extends the interconnecting piece for being useful for connection plug, and the periphery of the interconnecting piece is circumferentially arranged a groove, The first sealing ring 1 is provided in the groove, the first sealing ring 1 is for when ensureing that small-power multi-core socket device is connected with plug Leakproofness；Female terminal 4 is equipped with 7, and 7 female terminals 4 divide to be arranged for two rows, and a row is provided with 3, and another row is provided with 4, one end of female terminal 4 is coated in the jack housing 3, and the other end is pierced by from the protrusion lower surface；It is described to insert The top of seat shell 3 is provided with multiple connecting holes, and the connecting hole extends to one end of the female terminal 4, small for ensureing Female terminal 4 can be formed with the terminal in plug and be contacted when power multi-core socket device is connected with plug.

Further, four corners of the jack housing 3 are each provided with a screw through-hole, small-power multi-core socket device Further include screw, the screw passes through screw through-hole and is pierced by bottom surface and the motor formation connection of the jack housing 3.The spiral shell Silk bottom is less than 4 other end of the female terminal at a distance from 3 bottom of jack housing at a distance from 3 bottom of jack housing, in this way When so that jack housing 3 being connected on motor, the other end of female terminal 4 can be contacted with the leading wire stabilization in motor.

The jack housing 3 of the utility model is by 4 screw lockings on motor, and motor can make a protrusion cylinder The screw through-hole of jack housing is packed into, protrusion cylinder height can be less than socket flange 0.1mm, can increase screw through-hole in this way Depth, solve the problems, such as that motor housing wall thickness is inadequate.The jack design of the utility model is the welding female terminal of via hole type 4, it eliminates original socket and loses control of one's feelings the hidden danger of terminal, while directly making the thickness of contact part with 0.45 thickness plate cutting Size 0.45mm is very accurate and stablizes, and improves plug power because of the big and unstable problem of dimensional tolerance, while thick with 0.45 The timber intensity of degree has very big promotion than the structure that original 0.2 thickness is superimposed, and is not easy in external impacts using when female terminal 4 Lower deformation.In addition the structure of new female terminal 4 when product volume is big can use automatic assembling, convenient for reduce product at This.

Specific embodiment of the utility model is described above.It is to be appreciated that the utility model not office It is limited to above-mentioned particular implementation, those skilled in the art can make a variety of changes or change within the scope of the claims, This has no effect on the substantive content of the utility model.In the absence of conflict, the spy in embodiments herein and embodiment Sign can be arbitrarily combined with each other.
