Description
- The invention relates to a connector assembly for connecting a shielded cable to a printed circuit board according to the preamble of claim 1.
- Such a connector assembly is disclosed for example in EP-A-0374307. In this known connector assembly the insert of the second connector element projects beyond the metal housing and is received in the housing of the first connector element in the assembled position of the connector assembly. This first connector element keeps the second connector element at a distance from the printed circuit board. Thereby the shielding of the signal conductors is partially interrupted at the location of this first connector element. Due to the ever increasing requirements for the signal transmission in such connector assemblies, this interruption in the shielding is a disadvantage of this known connector assembly.
- The invention aims to provide an improved connector assembly of the above-mentioned type.
- To this end the connector assembly according to the invention is characterized by the features of claim 1.
- In this manner it is obtained that the walls of the metal housing are fully enclosing as a shielding the signal contacts up to the level of the printed circuit board so that there is no interruption at all in this shielding. Moreover the connector assembly according to the invention has the advantage that the signal contacts are enclosed by the walls of the metal housing both in the longitudinal and transverse direction.
- According to a preferred embodiment of the connector assembly according to the invention the first housing at at least one longitudinal side is provided with at least one upright, springy locking pin carrying a locking cam at its free end, while the metal housing at the corresponding longitudinal side(s) has an inwardly directed flange with a passing slot for each locking pin and a locking cam cooperating with the locking cam of the (each) locking pin in the assembled position of the contact assembly.
- Thereby a mechanical locking in the assembled position of the connector assembly is obtained in the first place, whereas in the second place the second connector element has to be brought in the correct position with respect to the first connector element to register each passing slot with the corresponding locking pin, whereby the different contacts of both connector elements will be registered before they contact each other.
- According to a favourable embodiment of the connector assembly according to the invention the metal housing is provided with an inlet element for the cable, said inlet element being mounted rotatably and lockable in the housing. Thereby the cable can be guided into the connector element under a desired angle with respect to the insertion side of the housing.
- The invention further provides a connector element to be used in the described connector assembly, comprising a housing formed of metal and having an insertion side, an insert of insulating material mounted in the housing, rows of female contacts received in the insert and at least one row of female ground contacts, said connector element according to the invention being characterized in that the metal housing is provided at its insertion side with a receiving space for a housing of a complementary connector element, wherein at least at one longitudinal side of the receiving space female ground contacts are provided as contact springs directed obliquely inwardly.
- The invention also provides a connector element, comprising a housing of insulating material with a plurality of rows of openings for receiving male signal contacts, wherein said connector element is characterized in that at at least one longitudinal wall slots are provided for receiving male ground contacts.
- The invention will be further explained by reference to the drawings in which an embodiment of the connector assembly of the invention is shown.
- Fig. 1 shows a perspective view of the connector assembly according to the invention in disengaged position, wherein the second connector element is shown in exploded view.
- Fig. 2 is a central cross section of the connector assembly of fig. 1 in assembled position.
- Fig. 3 is a side view of the second connector element of the connector assembly of fig. 1.
- Fig. 4 shows the inner side of a housing half of the second connector element.
- Referring to the drawings there is shown an embodiment of a connector assembly for connecting a cable 1 schematically shown in fig. 4 to a
printed circuit board 2. As shown in fig. 1, the connector assembly comprises a first connector element 3 having a first housing 4 of insulating material with upright longitudinal walls 5. Between the longitudinal walls 5 there are four rows ofmale signal contacts 6 fixed in a suitable manner in plated through-holes of the printedcircuit board 2, for example by a press-fit connection. The signal contacts 6 pass through fitting openings in the housing 4 and protrude freely in the space between the longitudinal walls 5. - In both upright longitudinal walls 5 there are provided outwardly open slots 7, in which
male ground contacts 8 are received and are accessible from the outside. Theseground contacts 8 are made in the same manner as thesignal contacts 6 and are fixed for example by a press-fit connection in openings of the printedcircuit board 2. In the described embodiment a row ofground contacts 8 is therefore present at both sides of the rows ofsignal contacts 6. - A
second connector element 9 is provided with ahousing 10 formed of metal. Thishousing 10 is assembled of twoidentical housing halves 11. Aninsert 12 of insulating material is mounted within thehousing 10, wherein a projectingedge 13 of theinsert 12 engages in aslot 14 at the inner side of thehousing 10.Female signal contacts 16 are received inopenings 15 of theinsert 12, saidfemale signal contacts 16 being schematically shown in fig. 2. The signal wires of the multi-wire cable 1 indicated in fig. 4 each are connected with afemale signal contact 16 in a usual manner. - As appears from fig. 2 in particular, the
insert 12 lies within thehousing 10, wherein areceiving space 17 is provided at the insertion side of thehousing 10, in which receivingspace 17 the housing 4 of the first connector element 3 can be fully received. Thereby thelongitudinal walls 18 and the transverse walls 19 of thehousing 10 adjoin the printedcircuit board 2 in the assembled position of the connector assembly according to fig. 2. - At the inner side of the
longitudinal walls 18female ground contacts 20 are provided protruding obliquely inwardly as contact springs and contacting themale ground contacts 8 in the assembled position. The cable 1 is guided into thehousing 10 through aninlet element 21 formed of metal, wherein theshielding 22 of the cable 1 is connected with theinlet element 21. - The described connector assembly has the advantage that the shielding extends from the cable 1 upto the level of the printed
circuit board 2 without any interruption. Further the signal contacts in thehousing 10 are fully enclosed both at the longitudinal sides and the transverse sides by thehousing 10 as a shielding. Thereby a high quality of the shielding of the connector assembly is obtained. - In fig. 1 and 4 it is indicated that the
female ground contacts 20 are part of acontact strip 23 attached to the inner side of thelongitudinal walls 18. - In the embodiment shown the housing 4 has at each longitudinal side two upright
springy locking pins 24 carryinglocking cams 25 directed towards each other. Thelongitudinal walls 18 of thehousing 10 are provided at the insertion side with inwardly directedflange edges 26 having a passing opening 27 for eachlocking pin 24. Thelongitudinal walls 18 are inwardly staggered above theinsert 12 through ashoulder part 28 in which a passage opening 29 is also provided for eachlocking pin 24. Alocking cam 30 is formed on theshoulder part 28, which lockingcam 30 is common to both lockingpins 24 of each longitudinal wall 5. In the assembled position shown in fig. 2 and 3, thelocking cams 25 engage behind thelocking cam 30, so that theconnector element 9 is mechanically locked on the connector element 3. Thereby any undesired detaching of theconnector element 9 is not possible anymore. Further the described embodiment with thelocking pins 24 shows the advantage that theconnector element 9 must be aligned with thepassage openings 27 to thelocking pins 24 and can only be slided on the locking pins in the correct position. Thereby thesignal contacts 16 andground contacts 20 of theconnector element 9 are already registered with thesignal contacts 6 andground contacts 8 of the connector element 3 before a connection between the different contacts is made. Deterioration of the contacts is thereby prevented. - In order to facilitate the unlocking of the
locking pins 24 guidingedges 31 are provided on the outer side of thelongitudinal walls 18, which guiding edges facilitate to align a tool for pressing thelocking pins 24 away from each other. These guidingedges 31 carrycams 32 at their end opposite of theshoulder part 28, at which cams a suitable tool for removing theconnector element 9 can engage. - In the embodiment shown in the drawings the
inlet element 21 is provided with acylinder section 33 with atoothing 34 schematically indicated in fig. 1. Thecylinder section 33 carries aninlet tube 35 through which the wires of the cable 1 are guided into thehousing 10.
