Connector
A connector includes a housing and a plurality of signal contacts and a plurality of ground contacts. Each contact includes a contact portion that contacts an object, a connection portion mounted on a substrate, and a fixing portion located between the contact portion and the connection portion in the vicinity of the connection portion. The signal contact and the ground contact are aligned and held in the housing, and the fixing portion is fixed to the housing. When the plurality of signal contacts are arranged between the ground contacts, at least two of the ground contacts are coupled and connected integrally or by a separate component, the coupling and connection being made in a section of each ground contact between one end (leading end) of the contact portion and the fixing portion, so that high-frequency transmission characteristics are improved.
1. A connector, comprising:
a plurality of contacts of two types, the plurality of contacts of two types being a plurality of signal contacts and a plurality of ground contacts,
each contact including,
a contact portion having a flat surface that contacts an object,
a connection portion mounted on a substrate, and
a fixing portion located between the contact portion and the connection portion and in a vicinity of the connection portion; and
a housing, wherein the signal contact and the ground contact are aligned and held in the housing and the fixing portion is fixed to the housing,
wherein the contact portion of each contact has a leading end and an end that is proximal to the fixing portion as compared to the leading end, and when the plurality of signal contacts are arranged between the ground contacts, at least two of the ground contacts are coupled and connected integrally with a coupling portion that has a surface extending from the flat surfaces of the contact portion of the ground contacts and is positioned at a section of each ground contact between the leading end of the contact portion and the fixing portion, so that high-frequency transmission characteristics are improved.
2. The connector according to claim 1 , wherein the at least two ground contacts are coupled and connected integrally in a section of each ground contact that is in a vicinity of the contact portion.
3. The connector according to claim 2 , wherein the ground contacts are coupled and connected within a range of 1 mm from a position at which the contact portion contacts an object.
4. The connector according to claim 1 , wherein in a case of integral coupling and connection, the coupling portion is formed by drawing or bending.
5. The connector according to claim 1 , wherein three ground contacts are coupled and connected together and two sets of two of the signal contacts are arranged between the ground contacts.
6. A connector, comprising:
a plurality of contacts of two types, the plurality of contacts of two types being a plurality of signal contacts and a plurality of ground contacts,
each contact including,
a contact portion having a flat surface that contacts an object,
a connection portion mounted on a substrate, and
a fixing portion located between the contact portion and the connection portion and in a vicinity of the connection portion; and
a housing, wherein the signal contact and the ground contact are aligned and held in the housing and the fixing portion is fixed to the housing, the housing comprising an insertion groove configured to receive the fixing portion,
wherein
the contact portion of each contact has a leading end and an end that is proximal to the fixing portion as compared to the leading end, and
when the plurality of signal contacts are arranged between the ground contacts, at least two of the ground contacts are coupled and connected integrally with a coupling portion that has a surface extending from the flat surfaces of the contact portion of the ground contacts and is made in a section of each ground contact between the leading end of the contact portion and the fixing portion, so that high-frequency transmission characteristics are improved.
7. The connector according to claim 6 , wherein the at least two ground contacts are coupled and connected integrally in a section of each ground contact that is in a vicinity of the contact portion.
8. The connector according to claim 7 , wherein the ground contacts are coupled and connected within a range of 1 mm from a position at which the contact portion contacts an object.
9. The connector according to claim 6 , wherein in a case of integral coupling and connection, the coupling portion is formed by drawing or bending.
10. The connector according to claim 6 , wherein three ground contacts are coupled and connected together and two sets of two of the signal contacts are arranged between the ground contacts.
11. The connector according to claim 6 , wherein the fixing portion is press-fit to the housing.
12. The connector according to claim 6 , wherein the insertion groove of the housing is configured to hold the fixing portion on both sides of the fixing portion.
13. The connector according to claim 1 , wherein the fixing portion is press-fit to the housing.
14. The connector according to claim 1 , wherein the housing comprises an insertion groove configured to receive the fixing portion.
