Description
The utility model is a kind of high density electrical connector, relates in particular to a kind of jockey with high density electrical connector of holding unit.
High development along with information industry, external electromagnetic field density increases, cause influencing each other between each transmission signal easily, so, the surface of exposing electronic device housing at the higher density electric connector all is provided with the metal baffle to prevent phenomenons generations such as cross-talk, distorted signals, and for reaching the ground connection of metal baffle, be provided with jockey, and by this jockey the holding unit group be fixed in to reach on the high density electrical connector and cover and the effect of ground connection one in high density electrical connector.
The holding unit of existing electric connector is mostly via being fixedly welded on the circuit board, the solder technology that it adopted have usually the through hole welding (Through Hole, TH) and the surface adhering welding (SurfaceMounting Technology, SMT).Because the weld part of surface adhering welding (SMT) has a larger area to contact with circuit board, can provide positioning action when terminal welds, help the operation that terminal welds and improve the quality.When surface adhering is welded usually, elder generation is at the surface coated tin cream of the desire welding of circuit board, then electronic component is inserted in set welding position, makes the tin cream fusing via infrared ray heating again, last is on cooling electronic components promptly is welded in both allocations on the circuit board.And what influence surface adhering welding (SMT) processing procedure is the solder side of electronic component and the same flatness of circuit board, and same flatness is high more, and the anchorage after the welding is good more.
See also existing high density electrical connector shown in Figure 1, it includes body 82, be located at the metal baffle 81 of body 82 1 sides and be located at the holding unit 83 of body 82 relative metal baffle 81 opposite sides and member such as jockey 84, wherein body 82 along its lengthwise to the two ends of a side be provided with cylindric through hole 821, and metal baffle 81 is respectively equipped with circular guide hole 811 and trepanning 831 with holding unit 83 relative these through holes 821.And holding unit 83 also is provided with the weld part 832 that docks with circuit board (not shown), and the convergence part 833 that connects weld part 832 and plane, trepanning 831 place.In addition, jockey 84 includes cylindric guide body 841 and the square shape end 842 of being located at guide body 841 1 ends.Pass the trepanning 831 of holding unit 83, the through hole 821 of insulating body 82 and the guide hole 811 of metal baffle 81 by means of the guide body 841 of jockey 84 and rivet afterwards and to this end, thereby make metal baffle 81 and holding unit 83 electrically connect to be grounded protection.Yet, please refer to shown in Figure 2, be not abutted against with the convergence part 833 of holding unit 83 end that is the square shape 842 of this existing jockey 84, and fail off normal spacing and when correcting convergence part 8 33 assemblings, thereby fail effectively to guarantee the weld part 832 of holding unit 83 and the same flatness of circuit board (not shown), and influence weld job and quality.In addition, jockey 84 is before riveted joint not, and existing design does not apply the power of additional location to jockey 84, and can't avoid coming off of jockey 84 in the assembling process, thereby influences packaging efficiency.
Main purpose of the present utility model is to provide the same flatness of a kind of solder side that can guarantee holding unit and circuit board to improve the high density electrical connector of welding quality.
Another purpose of the present utility model is to provide a kind of jockey that can prevent in assembling process to come off to improve the high density electrical connector of packaging efficiency.
The purpose of this utility model is achieved in that this high density electrical connector includes body, metal baffle, holding unit and jockey, wherein body has the terminal module, the metal baffle covers on the aforementioned body, and holding unit is located at the opposite side of body with respect to the metal baffle, the convergence part that it comprises junction, weld part and connects junction and weld part, this weld part is used with circuit board and is connected, and being provided with the solder side that connects with circuit board, the convergence part then is close proximity to the outside of constructing the installing space wall; Jockey is provided with guide body and in the end of one end, and the end that it is characterized in that this electrical connector is provided with on the convergence part that a stop surface is resisted against holding unit at least.
Prior art relatively the utlity model has and is beneficial to welding and avoids the coming off with the advantage of enhancing productivity of jockey in the assembling process.
Below in conjunction with diagram and preferred embodiment, the utility model is described in further detail.
Fig. 1 is the three-dimensional exploded view of existing high density electrical connector.
Fig. 2 is the sectional perspective constitutional diagram of existing high density electrical connector.
Fig. 3 is a three-dimensional exploded view of the present utility model.
Fig. 4 is a sectional perspective constitutional diagram of the present utility model.
See also Fig. 3 and shown in Figure 4, the utility model includes body 2, covers in the metal baffle 1 of body 2 one sides, is mounted on holding unit 3, jockey 4, the terminal module 5 of body 2 relative metal baffle 1 opposite sides and the structures such as positioning seat 6 that match with terminal module 5.Wherein body 2 includes the interface 21 and the composition surface 22 of docking with butt connector (not shown), and be convexly equipped with joint portion 211 in interface 21, and 211 be provided with the plurality of terminals mounting groove 212 that runs through interface 21 and composition surface 22 in the joint portion, in addition, 22 1 sides convex with installing space 221 on the composition surface, and 211 both sides, joint portion are provided with cylindric through hole 213, and these through hole 213 corresponding composition surfaces 22 are provided with a square groove 222.
