Description
- The invention relates to an electrical connector with a housing containing contacts attached to the electrical conductors of a cable, and in particular to a cap which can be mounted to a cable end of the housing to surround the cable tightly in order to protect the cavity from the ingress of dust and water.
- In the manufacture of electrical connectors it is common practice to provide connectors with housings having contact cavities for the accommodation of electrical contacts and with the corresponding contacts for making connection with the electrical conductors of a cable. Additionally, it is also known to provide the connector with caps that are fitted to the cable end of the housing that fit tightly around the trailing cable in order to protect the cavity from the ingress of dust and water. The employment of such caps in the motor vehicle industry is particularly beneficial. In addition to the protective function the cap can also fulfil a guiding function for the electrical conductors of the cable, and furthermore provide a strain-relief for the cable. An electrical connector with such a cap is, for instance, disclosed in US 5,762,520 (& EP-A-805 522).
- It is also generally known that the electrical contacts in the contact cavities of the housing should be secured. Such securing keeps the contact safely in the contact cavity even if there is a pull on the cable. Brazilian Patent Application PI 9501343-1A discloses an electrical connector which is provided with a contact securing device at the cable end. The contact securing device snaps into the housing and fits into the contact accommodating cavity around the electric conductor and behind the contacts, possibly behind a single wire seal, thus securing the contacts in the cavity. The contact securing device does not, however, protect from the ingress of dust and water into the housing.
- From US 4,372,634 a connector is known having a housing with contact cavities for electrical contacts attached to electrical conductors of a cable, and a cap that can be mounted on the housing at a cable end of the housing. The cap includes an integrated contact securing device for securing the contacts in the cavities and consists of two parts which can be joined together perpendicular to the plugging direction.
- Starting from this prior art, the objective of this invention is to provide a connector with a protection from the ingress of dust and water as well as a structure for securing the contacts therein, that is surely mounted when the cap is mounted.
- The objective is achieved by an arrangement with the features of
claim 1, whereby the special design of the cap ensures that when the cap is mounted to the housing the integrated contact securing device is also brought into its final position. This is achieved by joining the two parts of the cap to the housing by a positive guiding arrangement which operates in the plugging direction when moving the contact securing device into its final position. This positively guided arrangement is achieved by sliding slots incorporated in the cap parts and sliding blocks in the housing. Advantageous developments are stated in the respective dependent claims. - It is particularly advantageous that in addition to the housing only one other part is required, a cap, in order to both secure the contacts in their cavities and to protect the housing against the ingress of dust and water.
- It is particularly advantageous that the cap comprises two parts interconnected in a flexible manner, which ensures that the two parts can be handled as one part and not as separate entities.
- It is of further particular advantage that the cap is provided with a mechanical strain-relief for the cable.
- It is of further particular advantage that the ingress of dust and water is made more difficult. This is achieved by providing a dust protection lip which fits tightly around the cable.
- Referring to the figures, an embodiment of this invention will now be explained by way of example.
- Figure 1 is an isometric view of the claimed connector housing showing a housing and a cap in a position in which sliding blocks of the housing can be inserted into the corresponding sliding slots of the cap;
- Figure 2 is an isometric view corresponding to figure 1 taken from a different viewpoint of a side wall and the cable end;
- Figure 3 is also an isometric view corresponding to figure 1 taken essentially from the cable end of the connector housing;
- Figure 4 is a cross-sectional view through the connector housing shown in figure 1 to 3 with the electrical contacts being schematically indicated;
- Figure 5 is a cross-sectional view through figure 4 along the section line A-A;
- Figure 6 is an isometric view of the connector housing, essentially from its side with the sliding blocks at the housing already in the sliding slots of the cap;
- Figure 7 is a corresponding isometric view from the cable end;
- Figure 8 is an isometric view essentially from one side wall onto the claimed connector housing with fully mounted cap;
- Figure 9 is a corresponding isometric view of a housing with a fully mounted section of a cap;
- Figure 10 is a cross-sectional view through the housing with the cap fully mounted and the contacts indicated schematically; and
- Figure 11 is a cross-sectional view along the section line B-B of figure 10.

- Referring to figures 1 to 5, the general construction of the connector will now be explained. The claimed electrical connector includes a
connector housing 1 which, in turn, consists of two parts: ahousing 2 and acap 3. Thehousing 2 comprises two parallel rows of fourcontact cavities 4. Thecontact cavities 4 accommodateelectrical contacts 5, indicated schematically in figures 4 and 5. - The
cap 3 is pushed onto thehousing 2 fromcable end 7. Thecap 3 comprises twoparts parts semi-circular cable end 14. In when thesplit shells semi-circular parts 14 form a circular end which will tightly surround a cable (not shown). Within thesemi-circular end 14, a sealinglip 15 is formed to provide a seal around the cable, thus affording protection from dust and water. At the same time, thecable end 14 with itsdust protection lip 15 can function as a mechanical strain-relief. - The two
parts plastic bands 16. Theplastic bands 16 are flexible, thereby allowing the parts to be moved in relation to each other. - Within each of the
split shell parts contact securing device 17 is included. The contact securingdevice 17 takes the form of a comb-shaped rib configured to embrace a number of conductors of the cable when thecap 3 is joined together. Thecontact securing device 17 is provided withsemi-circular apertures 18 to accommodate respective electrical conductors. In addition, thecontact securing device 17 is provided with arib 19 that engages in acavity 4 when the cap is shifted in a longitudinal direction away from the cable end. - To lock the two
parts cap 3 together, eachpart corresponding latching arrangement part 12 of thecap 3 is provided with at least onelatching lug 21 whereas theother part 13 on the corresponding facing side is provided with alatching arm 20 having a latch opening 22. Latching arms with latching openings are also provided at the housing end of thecap 3. Theselatching elements 23 interact with thecorresponding latching lugs 11 at thehousing 3. - In addition to the elements discussed, the
housing 2 is provided with a pair of slidingblocks 24 at opposite sides near thecable end 7. In eachpart cap 3, a correspondingsliding slot 25 is located on facing sides. When thecap 3 is mounted to thecable end 7 of thehousing 2, thesliding blocks 24 in thesliding slots 25 are inserted first. If now an attempt is made to join theparts parts cap 3 will shift on thehousing 2 in the plugging direction. The twohalves ribs 19 of thecontact securing device 17 enter into thecavities 4. When the end position is reached, the twoparts complementary latch elements cap 3 has been pushed towards thehousing 2 in the plugging direction so that thelatching elements 23 also are latched with thecomplementary latching elements 11. Theribs 19 engage into thecavities 4 thus securing the contacts in thecavities 4. This arrangement is illustrated in figures 8 to 11. - Figures 1, 4 and 9 show clearly that adjacent to the sealing
lip 15 thecircular end 14 is provided with a furthersemi-circular rib 26. This rib can, for example, be employed as strain-relief.
