Embodiment
It is understandable to enable above-mentioned purpose of the present utility model, feature and beneficial effect to become apparent, below in conjunction with the accompanying drawings
Specific embodiment of the utility model is described in detail.
As shown in Fig. 1 to 2, the utility model embodiment provides a kind of D-Sub connectors, and D-Sub connectors include connection
Device housing 2 and D-Sub lock pins 1.D-Sub lock pins have lock pin body 11 and the connecting portion 12 being connected with lock pin body 11, wherein,
The both sides of connecting portion 12 have through hole, and bolt 3 coordinates with the bolt hole on connector shell 2 to be fixedly connected, passes connecting portion 12
On through hole, a diameter of 2.4~4.2mm on the head 31 of bolt 3.Perisporium 23 of the D-sub lock pins 1 along connector shell 2 is circumferential
The both sides in direction are equipped with bolt 3.
Inventor has found, because the clear size of opening of D-Sub lock pins is the unified size of standard, thus on connector shell with
The screwed hole size that through hole coordinates on D-Sub lock pins is fixed.Wherein, in the screw thread being screwed into bolt on connector shell
Kong Shi, the head of its bolt plays a part of screwing terminal positioning, when the end face of bolt and screwed hole periphery offsets, it is impossible to after
It is continuous to be screwed, bolt installation.
When the bolt used head diameter it is oversized if, head can be supported with the perisporium of connector shell
Touch, cause bolt not to be placed into screwed hole；And when the head diameter of bolt that use it is undersized if, head can not
The end face on bolt hole periphery is propped up, during bolt is screwed, it may occur that the head of bolt is screwed into screwed hole, then after
Continuous screw is dropped from screwed hole；In addition, when bolt head is undersized, because contact area is too small when tightening bolt, meeting
Cause screwdriver easily to be come off in the process tightened, made troubles to installation.
In the present embodiment, the diameter on the head of bolt 3 is arranged in the range of 2.4mm~4.2mm, bolt is ensure that
The diameter on head will not be excessive, will not be contradicted with the perisporium of connector shell, bolt can be placed into the spiral shell of connector shell
In pit；The diameter on the head of bolt also will not be too small, and head can prop up bolt hole, and bolt will not be from the spiral shell of connector shell
Dropped in pit, contact area is suitable when tightening bolt, and screwdriver is difficult for drop-off in the process tightened, easy for installation.
As shown in figure 3, the connecting portion 12 of D-Sub lock pins 1 is plate-like, the center of connecting portion 12 has D type holes, lock pin body
11 are inserted in formation D-Sub lock pins in D type holes.
As shown in figure 4, bolt 3 includes threaded portion 33, polished rod portion 32 and head 31, polished rod portion 32 is located at head 31 and screw thread
Between portion 33.With reference to shown in Fig. 1, bolt 3 insert connector shell 2 screwed hole in after, threaded portion 33 a part stretching
Screwed hole, for connecting D-Sub lock pins 1；Polished rod portion 32 is entirely located in screwed hole；Head 31 then props up screwed hole, prevents spiral shell
The fully extended screwed hole in line portion 33, bolt entirely slides from bolt hole.In the present embodiment, bolt 3 is with threaded portion, polished rod portion
With the bolt on head.Bolt 3 is also not necessarily limited to such a bolt, can be the only bolt with head and threaded portion.
As shown in figure 1, connector shell 2 includes perisporium 23, bottom plate 22 and cover plate 21, wherein perisporium 23, bottom plate 22 and lid
Plate 21 surrounds accommodating chamber.With reference to shown in Fig. 2, accommodating chamber is stretched into one end of D-Sub lock pins 1, and the other end stretches out connector shell 2.
There is perisporium 23 breach 23a, breach 23a to run through perisporium 23 along bottom plate 22 to the direction of cover plate 21.With reference to Fig. 2 institutes
Show, lock pin body 11 is inserted in breach 23a.
There is bottom plate 22 slit 22a, slit 22a to have two sides in breach 23a one end, and one of side is week
A part for wall 23, opposite side is outlying from perisporium 23, is set on the side away from perisporium 23 along bottom plate 22 to the direction of cover plate 21
Raised 22b, for blocking D-sub lock pins, prevents D-Sub from being come off from slit 22a.Slit 22a is passed through on its length direction
It is logical.With reference to shown in Fig. 2, the direction of the connecting portions 12 of D-sub lock pins 1 along cover plate 21 to bottom plate 22 is plugged in slit 22a.Its
In, the side that a side is not limited to a part for perisporium 23 or set outside perisporium.
Connector shell 2 has top 2a and afterbody 2b, and top 2a both sides are protruded out relative to afterbody 2b both sides.Connection
Device housing 2 is overall to look like the box body that one is T-shape, and top 2a accommodating chamber is used to accommodate D-Sub lock pins, afterbody 2b's
Accommodating chamber is used to accommodate the wire harness being connected with D-Sub lock pins.Wherein, 2a both sides in top are relative to the part that afterbody 2b both sides are protruded out
It is then the position for setting the screwed hole of connector shell 2, can so make it that the distance of screwed hole will not be long, it is ensured that with
The length for the bolt 3 that screwed hole coordinates will not be long.
As shown in Fig. 2 D-Sub connectors also include wiring clip shell 41, wiring clip shell 41 is located at the afterbody of connector shell 2
2b；With wire clamp cover plate 42, wire clamp cover plate 42 is connected by screw and wiring clip shell 41, and wire clamp cover plate 42 and wiring clip shell 41 are formed
Accommodate the cavity of wire harness.The side installing plate 41a of wiring clip shell 41 is inserted on afterbody 2b and D-Sub along cover plate 21 to the direction of bottom plate 22
In mounting groove 2c on the relative side of lock pin, it is fixedly connected with connector shell 2.
The multiple wire harness being connected with D-Sub lock pins are polymerized to an entirety in the top 2a of connector shell 2, via connector
The afterbody 2b of housing 2, is passed from wiring clip shell 41 and the cavity of the formation of wire clamp cover plate 42.Wire harness is set by a wire harness shroud, line
Beam tube has two layers, and the outer layer of wire harness pipe is insulating barrier, and internal layer is provided with screen layer, and screen layer can be formed by woven wire cloth, with
Play shielding action.
Include boss 51 in the accommodating chamber of connector shell 2, boss 51 is located at the afterbody 2b of connector shell 2；Shading ring
52, shading ring 52 is arranged on boss 51 by screw；With water conservancy diversion terminal 53, water conservancy diversion terminal 53 is arranged on boss 51 by screw
On.
The other end of water conservancy diversion terminal 53 is fixed on connector shell 2 and contacted with connector shell 2.Specifically, can be by
A tuftlet is drawn in screen layer, the end of screen layer is connected with water conservancy diversion terminal 53, and is enclosed outside screen layer as insulating barrier
Heat-shrink tube, to avoid disturbing between wire harness.
Thus, screen layer is by water conservancy diversion terminal 53 and the mediate contact of connector shell 2 and is electrically connected, even if shading ring 52
Loosening can not play shielding action, can ensure screen layer contact with connector shell 2 by water conservancy diversion terminal 53, so as to ensure
The shielding properties of D-Sub connectors.
Although the utility model is disclosed as above, the utility model is not limited to this.Any those skilled in the art,
Do not depart from spirit and scope of the present utility model, can make various changes or modifications, therefore protection domain of the present utility model
It should be defined by claim limited range.
