Abstract
The utility model relates to electrical connector technical field, in particular to a welding wire type terminal assembly structure, which comprises a terminal and an insulation main body for terminal assembly. The terminal has a contact part, a fixation part and a welding wire part; a connection section is arranged between the contact part and fixation part have; the fixation part is fixed outside the terminal hole of insulation main body. At this moment, the insulation main body is provided with a fixed groove at the external side of terminal hole. The fixed groove and terminal fixation part are coordinated to be installed; the width of connection section is more than the contact part and the formed stage is just clamped in the terminal hole during assembly. The utility model fixes up the terminal fixation part outside, widens the connection section so that stage formed in the connection section is just clamped in the terminal hole during assembly to cover the terminal hole without reserving any back and forth through clearance. The structure is not only convenient in the assembly, but also effectively stops the welding materials from expanding to the terminal contact part. Therefore, the normal operation of terminal is guaranteed.
Description
Technical field:
The utility model relates to technical field of electric connectors, refers in particular to wire welding type terminal group assembling structure.
Background technology:
Traditional electric connector, the terminal fixed part embeds in the terminal hole of insulating body, and utilizes the hangnail blocking of fixed part side, forms fixing assembling; This structural design, the width that the terminal fixed part occurs have the gap less than terminal hole after the assembling, when bonding wire connects, scolder easily takes place spread in the termination contact portion by the gap, influence terminal and electrically touch, and cause the connector quality to descend.
Summary of the invention:
It is a kind of simple in structure, easy to assembly that the purpose of this utility model is to provide, and the wire welding type terminal group assembling structure that can effectively stop scolder to spread.
For achieving the above object, the utility model adopts following technical scheme:
Wire welding type terminal group assembling structure, comprise terminal and the insulating body of assembling for terminal, terminal has contact site, fixed part and bonding wire portion, have one to be connected section between contact site and the fixed part, fixed part is fixed in outside the terminal hole of insulating body, at this moment insulating body is provided with holddown groove in the terminal hole outside, and holddown groove cooperates installation with the fixed part of terminal; Be connected the width of the width of section greater than contact site, the step of formation is equipped in the terminal hole when assembling just.
Holddown groove take shape in that the insulating body rear end protrudes out after on the section of prolonging, be spill; The terminal fixed part is provided with hangnail, and hangnail is equipped in the holddown groove; The terminal fixed part is in the straight insertion holddown groove.
The utility model is external fixing with the terminal fixed part, and corresponding widening is connected section, make the step that is connected section formation when assembling, be equipped in the terminal hole just, reach and be connected section covering terminal hole, the gap that connects before and after not staying, such structure is not only quite convenient in assembling, and can effectively stop scolder to spread to termination contact portion, guarantees the terminal operate as normal.

Embodiment:
Consult shown in Fig. 1～7, wire welding type terminal group assembling structure described in the utility model comprises terminal 10 and the insulating body of assembling for terminal 20.
Shown in Figure 1, terminal has contact site 11, fixed part 12 and bonding wire portion 13, have one to be connected section 14 between contact site 11 and the fixed part 12, be connected the width of the width of section 14 greater than contact site 11, be formed with step 141 thus, fixed part 12 and bonding wire portion 13 extend towards being connected section 14 rears, and width is relatively large, obtain enough structural strengths thus, also make things convenient for the bonding wire operation.Fixed part 12 and bonding wire portion 13 are flat, are connected 14 of sections and do bending relatively, to guarantee that contact site 11 has enough elasticity.Fixed part 12 left and right sides are provided with hangnail 121, to reach fixedly blocking.
Shown in Fig. 2,3, insulating body 20 is provided with terminal hole 21, inserts assembling for terminal; The section of prolonging 23 after insulating body 20 rear ends have also protruded out, after be provided with holddown groove 22 on the section of prolonging 23, holddown groove 22 extends and is communicated with terminal holes 21.
Terminal fixed part 12 is " Z " type structure with the terminal section of linking 14; During assembling, terminal fixed part 12 and linking section 14 blocking respectively are fixed in main body holddown groove 22 and the terminal hole 21, guarantee that " Z " type structure is indeformable.
Shown in Fig. 4～7, during assembling, terminal fixed part 12 is fixed in outside the terminal hole 21 of insulating body 20, cooperate installation with holddown groove 22, holddown groove 22 is a spill, fixed part 12 is in the straight insertion holddown groove 22, limits terminal fixed part 12 relatively and holddown groove 22 upper port also are provided with the cross break limit, prevents to upwarp; Terminal fixed part 12 is provided with hangnail 121, and hangnail 121 is equipped in the holddown groove 22, reaches to be connected.The contact site 11 of terminal passes terminal hole 21, is equipped in just in the terminal hole 21 and be connected section 14 steps 141 that form, and in the top terminals hole 21 corresponding rank, hole, i.e. formation is stopped up relatively; At this moment, be connected section 14 and hide terminal holes 21 relatively, cut off insulating body to being communicated with of socket and rear, like this, when bonding wire is operated, can effectively stop scolder to spread to termination contact portion, assurance terminal operate as normal.
The utility model effectively designs the terminal group assembling structure, not only can obtain well-formed's terminal, and also ease of assembly, and can improve scolder spreads to insulating body the place ahead from the insulating body rear problem, to obtain the connector of better quality.
